The present invention relates to methods and apparatus for providing wireless services to user equipment devices located at a customer premises. More particularly, the present invention relates to methods and apparatus for providing services, e.g., broadband services, to subscribers or users located within a customer's premises through the use of a plurality of different wireless communications paths, e.g., 5G wireless communications and WiFi wireless communications. The present invention further relates to method and apparatus for managing, reducing and/or eliminating congestion at a customer premises. The present invention further relates to methods and apparatus for providing services to customer premises equipment devices without the need for a landline connection to the customer premises in which the customer premises equipment devices are located.
In instances where wireless networks are being used to provide broadband services to a customer premises, the capacity of the wireless connection or link to the customer premises may not be the limiting factor but instead congestion on links, connections or communications paths within the customer premises may become a bottleneck for providing services. For example, such problems occur in Citizens Broadband Radio Service networks.
In a Citizens Broadband Radio Service (CBRS) network, Citizens Broadband Radio Service Devices (CBSDs) serve as access points which can support wireless communications with user equipment devices (UEs).
A CBRS network includes a plurality of CBSD devices. The CBSD devices provide wireless services to subscribers' user equipment devices. Spectrum is granted to each of the CBSDs using a centralized system called the Spectrum Access System (SAS), The Spectrum Access System is a central processing and database system that receives and processes spectrum grant requests. In the CBRS network, interference is managed through power management of CBSD devices by the Spectrum Access System (SAS). The SAS stores information regarding which CBSD uses how much spectrum at which location in the CBRS network.
Many customer premises, e.g., homes do not have landline connections or landline connections which can support broadband services. For example, in various geographical areas, e.g., rural areas of the country with sparse populations, it is not economical or practical to connect landlines to all customer premises, in such areas, there is a need for providing services, e.g., broadband services, to the customer premises which do not have landline connections or do not have landline connections which can provide broadband services. Additionally, in urban areas where landline connections can provide broadband services customers may still desire to have services provided via wireless connections in place of or in addition to landline connections.
In CBRS systems wherein broadband services are provided to a plurality of devices at the customer premises, e.g., user equipment devices, using a customer premise equipment that provides WI-FI services at the customer premise equipment, customer premises communications links can become congested affecting the level and quality of service that may be provided to the plurality of devices at the customer premises. While the devices at the customer premises may have the capability, to communicate using different wireless paths there is currently a technological problem of how to use multiple communications paths to send data to a user equipment device requesting the data.
From the above it should be understood that there is a need for new and/or improved methods and apparatus to provide wireless services, e.g., wireless broadband services, to subscribers or users located within a customer premises. There is a further need for new and/or improved methods and apparatus for providing services to devices located at customer premises without a landline connection or a landline connection capable of providing broadband services and/or where a landline is not practicable or economical. Additionally, there is a need for new and/or improved methods and apparatus for managing, reducing and/or eliminating bottleneck conditions which occur at a customer premises. There is also a need for new and/or improved methods and apparatus to solve the technological problem of how to overcome congestion problems when a customer premises does not have the link capacity to provide the requested services for a plurality of devices at the customer premises. Moreover, there is a need for new and/or improved methods of providing additional resources, e.g., bandwidth, to customer premises devices in addition to the landline and current wireless methods available.
The present invention provides a technological solution of how to provide wireless data services, e.g., broadband services to devices located at a customer premises while minimizing and overcoming congestion problems at the customer premises.

While various embodiments have been discussed in the summary above, it should be appreciated that not necessarily all embodiments include the same features and some of the features described above are not necessary but can be desirable in some embodiments. Numerous additional features, embodiments and benefits of various embodiments are discussed in the detailed description which follows.
The current invention is applicable to wireless networks, e.g., Citizens Broadband Radio Service (CBRS) networks, that provide wireless communications services, e.g., broadband services to user equipment devices at customer premises. The present invention solves the network congestion problems at customer premises that are receiving data services via wireless communication. Various embodiments of the present invention are directed to new apparatus and methods for providing wireless services, e.g., broadband data services, to devices located at a customer premises. While the invention is explained using an exemplary Citizens Broadband Radio Service network, it should be understood that the invention is not limited to Citizens Broadband Radio Service networks.
Citizens Broadband Radio Service networks are networks that include user equipment devices, e.g., mobile or wireless devices such as for example cell phones, smart phones, laptops, tablets, smart TVs, Citizens Broadband Radio Service Devices (CBSDs) which serve as access points/base stations, and Spectrum Access Systems which provides spectrum assignments and manage frequency interference through power management of the CBSDs transmission power. The Citizens Broadband Radio Service network utilizes the 150 megahetz in the 3550-3700 MHz band referred to as the 3.5 GHz Band. One important aspect of the CBRS network is the limitation of interference, e.g., radio transmission, from multiple transmission sources, e.g., multiple CBSD devices located near each other or in close proximity to one another. The CBRS network includes Spectrum Access Systems that obtain information about registered or licensed commercial users in the 3.5 GHz band from FCC databases and information about federal incumbent users of the band from ESC (Environmental Sensing Capability) system and interact directly or indirectly with CBSDs operating in the band to ensure that Citizens Broadband Radio Service users operate in a manner consistent with their authorizations and promote efficient use of the spectrum resource. Among the Spectrum Access System functions as defined in the Amendment of the Commission's Rules with Regard to Commercial Operations in the 3550-3650 MHz Band released Apr. 21, 2015 are that: it determines the available frequencies at a given geographic location and assign them to CBSDs; it determines the maximum permissible transmission power level for CBSDs at a given location and communicates that information to the CBSDs; it registers and authenticates the identification information and location of CBSDs; it enforces exclusion and protection zones, including any future changes to such Zones, to ensure compatibility between Citizens Broadband Radio Service users and incumbent federal operations; it protects Priority Access Licensees (PAL) from impermissible interference from other Citizens Broadband Radio Service users; ensures secure and reliable transmission of information between the SAS, ESC, and CBSDs; and it facilitates coordination and information exchange between SASs. Through the management of the CBSDs power transmission levels in a geographical area the SAS manages the radio interference in the geographical area.
Various embodiments of the present invention describe methods, apparatus, systems and techniques for providing wireless services, e.g., broadband services, to one or more devices at a customer premises. In the present invention, Citizen Broadband Radio Service spectrum, 3.5 GHz frequency spectrum band, is used to serve nomadic and stationary users. The invention is useful to provide broadband services to geographically isolated or remote areas, e.g., rural areas, where wired or optical connections are expensive and not economical given the number of customers to be serviced. The invention is also useful in urban areas where wireless services may be preferred as a replacement for wired connections or in addition to wired connections. In the present invention, a CBRS Customer Premise Equipment device (CPE) is located at a customer's premises inside of a house, business or any place where there are CBRS network users. The CBRS CPE device is coupled or connected to at least one CBRS fixed wireless access (FWA) tower base station (e.g., CBSD) over wireless communications links. The CBRS CPE is typically located in a building such as a home and is coupled to one or more antennas or an antenna array through which the CBRS CPE device transmits to and receives from the antenna(s) of the CBRS FWA tower base station (CBSD) wireless signals over the wireless communications link. These wireless communications links being in the 3.5 GHz frequency spectrum band. The CBRS CPE device in some embodiments includes external antennas. In some embodiments, the CBRS CPE device includes one or more internal antennas. In some embodiments, the CBRS CPE device includes one or more internal antennas and one or more antenna ports to which one or more external antennas are connected. The CBRS CPE device is coupled through a wired connection, e.g., a cable to one or more Wireless Fidelity (Wi-Fi) Access Points. The CBRS CPE device also referred to herein as CPE device or CPE serves the subscribers or users located in its coverage area, e.g., in the house, building, or on the customer's premises. The one or more Wi-Fi access points provide Wi-Fi services to the one or more end point devices or user equipment devices located at the customer premises. The one or more Wi-Fi access points are connected over a cable or wired communications to the CBRS CPE device through which backhaul is provided. One or more of the one or more endpoint devices or user equipment devices are dual mode devices that support both CBRS wireless protocols, e.g., 5G wireless protocols, and Wi-Fi protocols. The dual mode devices, e.g., phones, are both wireless 5G enabled and Wi-Fi enabled with two different radios one for each type of wireless protocol. These dual mode endpoint devices or user devices can connect to both wireless networks at the same time and communicate using the two different wireless protocols, e.g., 5G wireless protocols and Wi-Fi protocols, at the same time with respect to a single packet data stream wherein some packets of the packet stream are routed over a first path (e.g., direct 5G wireless protocol path to the end point device) and other packets of the same packet stream are routed via a second path (e.g., indirect Wi-Fi path) to the endpoint device. The end point device then combines/assemblies the data from the packets received from both paths to obtain the data of the packet stream. In connection with the discussion of 5G wireless protocol, MAC layer and the Packet Data Convergence Protocol, the 3GPP TS 38.323 V15.6.0 (2019 June) (3rd Generation Partnership Project; Technical Specification Group Radio Access Network; NR; Packet Data Convergence Protocol (PDCP) specification (Release 15) is a specification which describes the 5G PDCP and is hereby expressly incorporated by reference in its entirety. The IEEE Std 802.11-2016, IEEE Standard for Information technology—Telecommunications and Information Exchange Between Systems Local and Metropolitan Area Networks−Specific Requirements Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications approved Dec. 7, 2016 describes the WI-FI MAC layer and is hereby expressly incorporated by reference in its entirety.

The second set of data packets being transmitted to the CPE device for delivery to the second user equipment device (e.g., UE 2118) in the first wireless protocol format over the wireless connection or link, e.g., link 166, established between the CPE device and wireless base station. The second set of data packets belonging to a packet stream whose packets are sent over a single path to the user equipment device. The packets being received at the CPE device, e.g, CPE 1112, in the first wireless format and being communicated by the CPE device to the Wi-Fi Access Point (e.g., Wi-Fi AP 1122) servicing the second user equipment device (e.g., UE 2118) to which the second set of data packets are being sent. The packets being communicated over the communications link (e.g., link 121) connecting the CPE device (e.g., CPE 1112) and Wi-Fi Access Point (e.g., Wi-Fi AP 1122). The packets being received at the Wi-Fi Access Point. The Wi-Fi Access Point converts the packets into Wi-Fi packets or generates Wi-Fi packets based on the received packets and transmits the converted or generated Wi-Fi packets to the second user equipment (e.g., UE 2118) in Wi-Fi format over the Wi-Fi channel or link (e.g., link 132) connecting the Wi-Fi Access Point (e.g., Wi-Fi AP 1122) to the second user equipment device (e.g., UE 2118). The second user equipment device (e.g., UE 2118) receives each of the packets at its Wi-Fi interface. The second user equipment device checks whether the packet is marked as containing data in Wi-Fi data format and if so processes the data otherwise sends over a link (e.g., a wire or trace) the information in the Wi-Fi MAC data packet unit to another wireless interface at the user equipment device (e.g., an interface handling data in the first wireless format such as a 5G interface if the first wireless format is a 5G wireless format). In this example, each of the packets of the second set of packets are marked as containing a MAC packet data unit containing data in the Wi-Fi data format and the Wi-Fi interface of the second user equipment device processes the received data.
In sub-step 2074, the wireless base station transmits a third set of data packets to the third user equipment device, e.g., UE 1119, in response to the third data service request it received from the third user equipment device. The third set of data packets being transmitted to the CPE device for delivery to the third user equipment device (e.g., UE 3119) in the first wireless protocol format over the wireless connection or link, e.g., link 166, established between the CPE device and wireless base station. The third set of data packets belonging to a packet stream whose packets are sent over a single path to the user equipment device. The packets being received at the CPE device, e.g, CPE 1112, in the first wireless format and being communicated by the CPE device to the Wi-Fi Access Point (e.g., Wi-Fi AP 2124) servicing the third user equipment device (e.g., UE 3119) to which the third set of data packets are being sent. The packets being communicated over the communications link (e.g., link 123) connecting the CPE device (e.g., CPE 1112) and Wi-Fi Access Point (e.g., Wi-Fi AP 2124). The packets being received at the Wi-Fi Access Point. The Wi-Fi Access Point converts the packets into Wi-Fi packets or generates Wi-Fi packets based on the received packets and transmits the converted or generated Wi-Fi packets to the third user equipment (e.g., UE 3119) in Wi-Fi format over the Wi-Fi channel or link (e.g., link 134) connecting the Wi-Fi Access Point (e.g., Wi-Fi AP 1124) to the third user equipment device (e.g., UE 3119). The third user equipment device (e.g., UE 3119) receives each of the packets in the third set of packets at its Wi-Fi interface. The third user equipment device checks whether the packet is marked as containing data in Wi-Fi data format and if so processes the data otherwise sends over a link (e.g., a wire or trace) the information in the Wi-Fi MAC data packet unit to another wireless interface at the user equipment device (e.g., an interface handling data in the first wireless format such as a 5G interface if the first wireless format is a 5G wireless format). In this example, the packets of the third set of packets are marked as containing a MAC packet data unit containing data in the Wi-Fi data format and the Wi-Fi interface of the third user equipment device processes the received data. Operation proceeds from step 2068 via connection node D 2076 to step 2130 shown on
In step 2130, the CPE device monitors for downlink congestion in each of the links between the CPE device and the one or more Wi-Fi Access Points to which it is connected. Step 2130 in some embodiments includes one or more sub-steps 2132 and 2134. In sub-step 2132, the CPE device monitors each of the links connecting a Wi-Fi Access Point to the CPE device for more than a first threshold number of expected data packets in the buffer for the Wi-Fi Access Point for a predetermined period of time. In sub-step 2134, the CPE device monitors each of the downlink buffers for each of the links connecting a Wi-Fi Access Point to the CPE device for a buffer overflow condition. The down link buffers being buffers in the CPE device, memory or registers of the CPE device. In some embodiments, each communications link (e.g., link 121, 123, . . . , 125) between the CPE device and a Wi-Fi Access Point has its own downlink buffer. Operation proceeds from step 2130 to step 2136.
In step 2136, when the CPE device (e.g., CPE 1112) detects congestion in one or more of the links between the CPE device and the one or more Wi-Fi Access Points to which the CPE device is connected, e.g., via a downlink buffer overflow condition or more than a first threshold number of expected data packets being in the downlink buffer for a predetermined period of time, the CPE device: (i) generates and communicates an Access Point (AP) Data Overload message to the wireless base station (e.g., CBSD 1102) over the wireless communications link (e.g., link 166) connecting the CPE device and the wireless base station in the first wireless protocol format; (ii) requests Wi-Fi Access Points to which the CPE device is connected provide information including AP identification information (e.g., IDs, Medium Access Control (MAC) addresses, Hardware addresses), and identification of user equipment devices to which the Wi-Fi Access Point is providing services; (iii) communicates the Wi-Fi Access Point information to the wireless base station. Operation proceeds from step 2136 to step 2138.
In step 2138, in response to receiving the AP data overload message, the wireless base station, e.g., CBSD 1102, generates a “MAC coordination message”. In some embodiments, the Wi-Fi Access Point information including the Wi-Fi Access Point identification information is included in the AP data overload message. In some embodiments, the Wi-Fi Access Point information is sent in a separate message from the “AP data overload message” in which case it is received and processed as a separate message at the wireless base station in a separate operation from the receipt of and processing of the AP data overload message operations. In some embodiments, the MAC coordination message is generated based on Wi-Fi Access Point information. Operation proceeds from step 2138 to step 2140.
In step 2140, the wireless base station, e.g., CBSD 1102, transmits the generated “MAC Coordination Message” to the CPE device in the first wireless protocol format. Operation proceeds from step 2140 to step 2142.
In step 2142, the CPE device forwards or transmits the “MAC Coordination Message” to the Wi-Fi Access Points to which it is connected (e.g., Wi-Fi AP 1122, Wi-Fi AP 2124, . . . , Wi-Fi AP N 126 in order to start coordination between the wireless base station, the CPE device and Wi-Fi Access Points regarding dual path packet stream delivery to user equipment devices which requires MAC packet layer conversion for data packets which are communicated to a user end device via a Wi-Fi Access Point. Operation proceeds from step 2142 to step 2144.
In step 2144, the Wi-Fi Access Points in response to receiving the MAC Coordination Message switch from operating in a non-MAC coordination mode of operation to operating in a MAC coordination mode of operation. In the MAC coordination mode of operation the Wi-Fi Access Points use a MAC converter layer on top of the MAC layer of a received packet destined for a user equipment device to encode the packet which is in the first wireless protocol format into a Wi-Fi protocol format. Diagram 1100 of
Returning now to step 2144, once the Wi-Fi Access Points have placed them in MAC coordination mode, operation proceeds from step 2144 to step 2146.
In step 2146, the wireless base station determines which packets are transmitted to user equipment devices through which Wi-Fi Access Points connected to the CPE device at the customer premises based on the Wi-Fi Access Point information provided by the CPE device to the wireless base station. Operation proceeds from step 2146 to step 2148 shown on
In step 2148, the wireless base station determines which user devices at the customer premises, e.g., customer premises 1114, are directly connected to the wireless base station via alternative wireless connections/links (e.g., 5G wireless connection, CBRS wireless connection, or cellular wireless connection) using the first wireless protocol. In the example system 100, user equipment device 1116 is connected via wireless communications link 190 to the wireless base station 102, user equipment device 2118 is connected via wireless communications link 191 to the wireless base station 102, user equipment device 3119 is connected via wireless communications link 192 to the wireless base station 102, user equipment device M 120 is connected via wireless communications link 193 to the wireless base station 102. The wireless base station in the exemplary embodiment is using a first wireless protocol, e.g., the 5G wireless protocol, to communicate with the CPE 1112, UE 1116, UE 2118, UE 3119 and UE M 120 over the communications links 166, 190, 191, 192, and 193 respectively. In some embodiments step 2148 includes sub-step 2150.
In sub-step 2150, when a user equipment device directly connects or attaches to the wireless base station, e.g., CSBD 1102, using the first wireless protocol, the wireless base station determines whether there are packets being sent to the user equipment device via the CPE device based on matching the user equipment device's International Subscriber Mobile Identity (IMSI) to the user equipment's MAC ID. Operation proceeds from step 2148 to step 2152.
In step 2152, the wireless base station on receiving confirmation that the CPE device and Wi-Fi Access Points have entered into MAC Coordination mode of operation in response to receiving the MAC Coordination Mode message from the wireless base station, switches from a non-MAC Coordination Mode of operation to a MAC Coordination Mode of operation, said switching from a Non-MAC Coordination Mode of operation to a MAC Coordination Mode of operation including: (i) maintaining the current flow of downlink data packets, e.g., Internet Protocol packets, through the current transmission path including the CPE device, Wi-Fi Access Points, Wi-Fi wireless connections to the user equipment devices; (ii) when a user equipment device request for additional data that is of a different traffic type or traffic types with different Quality of Service (QoS) is received via the CPE device from a user equipment device whose downlink data is determined to be traversing a congested link between the CPE device and the Wi-Fi Access Point supporting the user equipment device making the request and it is determined that the alternative wireless connection between the wireless base station and the user equipment device making the request for additional data has sufficient capacity to support the transmission of the additional data requested, the wireless base station transmits the additional traffic data in response to the request for additional data over the alternative wireless connection or network path established between the user equipment device making the request and wireless base station using the first wireless protocol (e.g., 5G wireless protocol, CBRS wireless protocol or cellular wireless protocol); (iii) when a user equipment device request for additional data that is of a different traffic type or traffic types with different Quality of Service (QoS) is received via the CPE device from a user equipment device whose downlink data is determined to be traversing a congested link between the CPE device and the Wi-Fi Access Point supporting the user equipment device making the request and the alternative wireless connection between the wireless base station and the user equipment device making the request is determined not to have sufficient capacity to support the additional data requested, the wireless base station transmits the additional data to the requesting user equipment device using data transmission coordination, data transmission coordination including transmitting some of the additional traffic data packets in response to the request for additional data over the alternative wireless network path or connection established between the user equipment device making the request and the wireless base station using the first wireless protocol format and transmitting the rest of the packets of the additional data requested over the path including the CPE device and Wi-Fi Access Point to the user equipment device, data packets in the additional traffic flow of additional data being marked to indicate packets which are sent through the alternative wireless network connection, e.g., 5G connection, and which packets are sent over the path including the CPE device and Wi-Fi Access Point to the user equipment device as previously discussed in connection with
In optional step 2154, the wireless base station determines which Wi-Fi Access Points connected to the CPE device provide the best channel conditions for the user equipment devices to which the wireless base station is connected, e.g., via probes based on Wi-Fi channel quality estimation, e.g., in accordance with the Wi-Fi 802.11 protocol. For example, in system 100 the wireless base station 102 is connected to the UE 1116, UE 2118, UE 3119, and UE M 120 via wireless communications links 190, 191, 192 and 193 respectively. The wireless base station can send a command to each of these user equipment devices and request that they perform a probe to determine Wi-Fi channel quality and report back the results to the wireless base station. Operation proceeds from optional step 2154 to optional step 2156.
In optional step 2156, the wireless base station transmits instructions to one or more user equipment devices (e.g., UE 1116, UE 2118, UE 3119, UE M 120) connected to the Wi-Fi Access Points (e.g., WiFi AP 1122, WiFi AP 2124, WiFi AP N 126) at the customer premises (e.g., customer premises 1114) to drop there current Wi-Fi Access Point connection and establish a new Wi-Fi Access Point connection with a Wi-Fi Access Point that will provide a better channel condition (e.g., a Wi-Fi Access Point that does not have a congested link between the CPE device and the Wi-Fi Access Point. For example in connection with system 100, the wireless base station 102 may determine that the link 121 is congested while the link 123 is not congested and may further determine that UE 2118 is able to attach to WiFi AP 2 based on the Wi-Fi channel quality probes. Upon making these determinations the wireless base station sends a command to the UE 2118 to drop the Wi-Fi connection 132 to Wi-Fi AP 1122 and establish a connection with WiFi AP 2124 thereby reducing the downlink congestion on the link 121 as the downlink traffic for UE 2118 will now traverse link 123 instead of link 121. Similarly the other UE devices at the first customer premise may, and in some embodiments are, commanded to change the WiFi Access Points to which they are connected therein the wireless base station is able to manage the traffic routing at the customer premises to reduce traffic congestion and optimize traffic routing at the customer premises. Operation proceeds from optional step 2156 to step 2158. In those embodiments which do not implement optional steps 2154 and 2156 operation proceeds directly from step 2152 to step 2158.
In step 2158, when the additional data traffic flow or session is completed to the user equipment device that requested the additional data, the wireless base station determines with respect to the user equipment device whether to: (i) drop the Wi-Fi connection for a pre-determined period of time to relieve the CPE device to Wi-Fi Access Point downlink congestion and transition all downlink data for the user equipment device through the alternative wireless path, (ii) continue in dual path mode of operation (using alternative wireless connection and Wi-Fi connection path with MAC coordination), or (iii) continue with the CPE device Wi-Fi connection and drop the alternative connection based on the determined quality of the alternative path signaling conditions. In some embodiments, the step 2158 includes one or more sub-steps 2160, 2162, and 2164.
In sub-step 2160, when the quality of the alternative path (e.g., 5G wireless connection, CBRS wireless connection, or cellular wireless connection) downlink signaling conditions between the wireless base station and the user equipment device is very good, e.g., the user equipment device can receive good downlink data packet throughput, then the wireless base station will run a test to check the uplink signal quality and if the uplink signal quality is also very good the wireless base station will instruct the user equipment device to drop the Wi-Fi connection for a predetermined amount of time to relieve the CPE-Wi-Fi Access Point link congestion transitioning any downlink traffic and uplink traffic onto the alternative wireless connection. Whether the downlink signaling conditions on the alternative path are very good is determined by determining if the downlink signaling conditions meet or exceed a downlink threshold. Whether the uplink signaling conditions on the alternative path are very good is determined by determining if the uplink signaling conditions on the alternative path meet or exceed an uplink threshold.
In sub-step 2162, when the signaling conditions between the wireless base station and the user equipment device are average or do not meet an average threshold value, then dual path mode of operation using the alternative wireless connection and the Wi-Fi transmission via Wi-Fi Access Point path will continue wherein the Wi-Fi Access Point performs the MAC layer conversion operation on packets transmitted from the wireless base station to the user equipment device via the Wi-Fi Access Point.
In sub-step 2164, when the signaling conditions between the wireless base station and the user equipment device are experiencing frequent fluctuations, e.g, because the SAS is changing power levels or there is frequency interference, then dual path mode of operation will be terminated and the downlink data will be sent from the wireless base station to the user equipment device via the Wi-Fi Access point path. Operation proceeds from step 2158 to step 2166 shown on
In step 2166, the customer premises equipment device, e.g., CPE 1112, continues to monitor the downlink congestion on the links connecting the customer premises equipment device and Wi-Fi Access Points and when the customer premises equipment device determines that the congestion has been cleared for a predetermined amount of time (e.g., no overflow of the link buffers or the number of packets in the link buffers falls below a threshold value), the customer premises equipment device generates a message indicating that the Wi-Fi Access Point Overload condition no longer exists at the customer premises. The customer premises equipment device then transmits the generated message to the wireless base station. In some embodiments, the operations of monitoring the downlink congestion, determining the overload condition no longer exists, generating the message indicating the Wi-Fi Access Point overload condition no longer exists and the transmission of the message to the wireless base station are separate steps. Operation proceeds from step 2166 to step 2168.
In step 2168, the wireless base station receives the message indicating that the Wi-Fi Access Point overload condition no longer exists at the customer premises. Operation proceeds from step 2168 to step 2170.
In step 2170, the wireless base station in response to receiving the message indicating that the Wi-Fi Access Point overload condition no longer exists at the customer premises generates a message to the customer premises equipment device and Wi-Fi Access Points at the customer premises to switch from operating in the MAC coordination mode of operation to the Non-MAC coordination mode of operation which includes no longer performing the MAC layer conversion on packets as dual path mode operation is not performed in Non-MAC coordination mode of operation. Operation proceeds from step 2170 to step 2172.
In step 2172, the wireless base station transmits the generated message to switch from operating in the MAC coordination mode of operation to the Non-MAC coordination mode of operation to the customer premises equipment device. Operation proceeds from step 2172 to step 2174.
In step 2174, the customer premises equipment device receives the message to switch from operating in the MAC coordination mode of operation to the Non-MAC coordination mode of operation and forwards/communicates the message to the Wi-Fi Access Points to which it is connected at the customer premises. Operation proceeds from step 2174 to step 2176.
In step 2176, the customer premises equipment device and the Wi-Fi Access Points send an acknowledgement, e.g., an acknowledgement message, to the wireless base station that they have switched to the Non-MAC coordination mode of operation. Operation proceeds from step 2176 to step 2178.
In step 2178, the wireless base station on receiving the acknowledgement from the customer premises equipment device and Wi-Fi Access Points switches from operating in the MAC coordination mode of operation to the Non-MAC coordination mode of operation thereby ceasing sending packets of a packet stream to the user equipment devices at the customer premises via dual paths. Thus no packets sent to the user equipment devices at the customer premises are marked for MAC layer conversation. Operation proceeds with the wireless base station providing data services to the user equipment devices via the CPE device and Wi-Fi Access Points. Operation proceeds from step 2178 via connection node D 2076 to step 2130 where the CPE device continues to monitor for congestion at the customer premises equipment devices and the method 2000 proceeds as previously described.
Typically, regardless of the mode of operation if the alternative path to the user equipment device is dropped the user equipment device will always default to attaching to a Wi-Fi Access Point and receiving data services over the Wi-Fi Access Point. In this way, even if there is congestion the user equipment device will still receive some level of service.
The method 2000 provides the technological solution of how to provide wireless data services, e.g., broadband services, to devices located at a customer premises while minimizing and overcoming congestion problems at the customer premises. The various embodiments described in connection with method 2000 provide new and novel methods for efficiently and effectively identifying, managing, reducing and/or eliminating congestion, e.g., link congestion, at a customer premises so that data services can be provided to subscribers and/or user equipment devices located at the customer premises via wireless connections.
In some embodiments, the wireless base station selectively determines which Wi-Fi Access Points to command to go into MAC coordination mode of operation based on which Wi-Fi Access Points are being affected by the Wi-Fi Access Point overload condition. For example, Wi-Fi Access Points experiencing downlink congestion are placed in MAC coordination mode of operation in which dual path mode of operation is used to send packets of a packet stream to user equipment devices being serviced by the Wi-Fi Access Point corresponding to the overload conditions while Wi-Fi Access Points which are not experiencing an overload condition remain in the Non-MAC coordination mode of operation.
Various features of the inventions will now be described in connection with

The link 1308 between the CPE device and the Wi-Fi Access Point is limited in its capacity to carry data to all three Wi-Fi enabled user equipment devices UE 9, UE 10, and UE 11. Therefore even though these user equipment devices request data in downlink, the link 1308 in some situation creates a bottleneck, i.e., congestion on the link, limiting the amount of data that can be sent to the user equipment devices UE 9, UE 10, UE 11 which are requesting the data. To compensate for this bottleneck condition, the user equipment devices which are also 5G wireless protocol enabled can receive data through a separate 5G wireless connection between the user equipment devices and the wireless base station 1302. To achieve this the system enters a MAC-coordination mode of operation in which packets of a packet stream are sent over two paths to the user equipment device one path being a direct 5G wireless protocol connection and the other being the path including the Wi-Fi connection. With respect to the path including the Wi-Fi connection, 5G packet data and associated information are sent over the Wi-Fi connection by the Wi-Fi Access Point by performing a MAC conversion layer operation on the received packet.
In step 1708, the CPE device 1306 generates message 1710 requesting the Wi-Fi AP 1310 to provide details about the Wi-Fi AP 1310 including identification information (e.g., ID, MAC Address, Hardware Address for the Wi-Fi AP 1310) and information, e.g., identification information, about the UEs the Wi-Fi AP is currently servicing which in this case includes UE 9, UE 10, and UE 11. Operation proceeds from step 1708 to step 1712.
Returning to step 1706, in step 1706 the wireless base station 1302 receives and processes the AP overload message 1704 detecting based on the AP overload message that there is overload condition at the customer premises, e.g., congestion on the CPE device to Wi-Fi AP link. Operation proceeds from step 1706 to step 1707. In step 1707, the wireless base station switches from Non-MAC coordination mode of operation to MAC coordination mode of operation.
In step 1712, the Wi-Fi AP 1310 receives and processes the message 1710 requesting Wi-Fi AP 1310's information. Operation proceeds from step 1712 to step 1714. In step 1714, the Wi-Fi AP 1310 generates message 1716 and transmits it to the CPE device 1306. The message 1716 includes the requested Wi-Fi AP 1310 details, e.g., identification information and information about the user equipment devices it is servicing. Operation proceeds from step 1714 to step 1718.
In step 1718, the CPE device 1306 receives and processes the message 1716. Operation proceeds from step 1718 to step 1720.
In step 1720, the CPE device 1306 generates Wi-Fi AP details message 1722 and transmits it to the wireless base station 1302. The Wi-Fi AP details message 1722 includes the information received in the message 1716 from the Wi-Fi AP 1310. Operation proceeds from step 1720 to step 1724.
In step 1724, the wireless base station 1302 receives and processes the Wi-Fi AP details message 1722. Operation proceeds from step 1724 to step 1726.
In step 1726, the wireless base station 1302 generates the MAC coordination message 1728 and transmits it to the CPE device 1306. The MAC coordination message 1728 may include information based on the Wi-Fi AP details received in Wi-Fi AP details message 1722 such as an identification of the Wi-FI AP to be placed in MAC coordination mode of operation. Operation proceeds from step 1726 to step 1730.
In step 1730, the CPE device 1306 receives the MAC coordination message 1728 and processes it. Operation proceeds from step 1730 to step 1732.
In step 1732, the CPE device 1306 generates MAC coordination message 1734 and transmits it to the Wi-Fi AP 1310. The MAC coordination message 1734 is based on the MAC coordination message 1728 received from wireless base station 1302. Operation proceeds from step 1732 to step 1736.
In step 1736, the Wi-Fi AP 1310 receives and processes the MAC coordination message 1734. Upon processing the MAC coordination message 1734 and in response to the MAC coordination message, the Wi-Fi AP 1310 switches from a Non-MAC coordination mode of operation to a MAC coordination mode of operation. Operation proceeds from step 1736 to step 1737. In step 1737, the Wi-Fi AP 1310 turns on MAC layer converter. Packets received marked for MAC layer conversion (e.g., 5G flag set to 1 and Wi-Fi flag set to 1 as described in connection with
In step 1738, the Wi-Fi AP 1310 generates and transmits MAC coordination confirmation message 1740 to the CPE device 1306. The MAC coordination message confirmation indicating that the Wi-Fi AP 1310 has switched to the MAC coordination mode of operation. Operation proceeds from step 1738 to step 1742.
In step 1742, the CPE device 1306 receives and processes the MAC coordination confirmation message 1740. Operation proceeds from step 1742 to step 1744.
In step 1744, the CPE device generates and transmits the MAC coordination confirmation message 1746 to wireless base station 1302. The MAC coordination confirmation message 1746 being based on the MAC coordination confirmation message 1740 and indicating that Wi-Fi AP 1310 has switched to MAC coordination mode of operation. Operation proceeds from step 1744 to step 1748.
In step 1748, the wireless base station receives and processes the MAC coordination confirmation message 1746. Operation proceeds from step 1748 to step 1750.
In step 1750, the wireless base station begins sending a first set of packets from a first data stream through the 5G wireless connection to the UE 91312 and a second set of packets from the first data stream through the Wi-Fi path. The first and second set of packets being different packets. The packets being sent through the Wi-Fi path include an indication or mark included in the packet by the wireless base station indicating the packets are 5G over Wi-Fi packets which the Wi-Fi AP 1310 is to perform a MAC layer conversion operation on in which the 5G PCDP packet information is placed in the MAC PDU of the Wi-Fi frame as shown in diagram 1100 of
