That is to say, there is no need for a built-in cellular communication module in the network access device, and only several communication interfaces for detachable connection with external cellular communication devices need to be reserved. In this way, by providing cellular communication devices with various network standards, it can be realized that one kind of network access device can meet different networking requirements of various customers in various occasions.

In addition, some processes described in the specification, claims and the above-mentioned drawings of the present application include a plurality of operations that appear in a specific order, and these operations may be performed out of the order in which they appear here or in parallel. The sequence numbers of operations, such as 101 and 102, are only used to distinguish different operations, and the sequence numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be performed sequentially or in parallel. It should be noted that the descriptions of “first” and “second” herein are used to distinguish different messages, devices, modules, etc., and do not represent the sequence, nor do they limit that “first” and “second” are different types.
The number of the communication interface 110 on the network access device 11 may be at least one. The number of the cellular communication device 12 may be at least one. The number of the communication interface 110 on the network access device 11 and the number of the cellular communication device 12 may be the same or different, which is not specifically limited in this embodiment of the present application.
The above-mentioned network access device can provide network access function to a user terminal. The network access device may be an electronic device such as CPE (Customer Premise Equipment, customer premise equipment), a gateway device, a wireless router, etc., and can receive a cellular signal (also called a mobile signal) of a base station through the cellular communication device detachably connected thereto, and convert the cellular signal into a WIFI signal or an Ethernet signal. Of course, it can also accept a WIFI signal or a wired signal. The network access device can convert a high-speed 4G or 5G network signal into a WIFI signal or an Ethernet signal to communicate with a terminal, and can be widely used as a wireless network access device in rural areas, cities, hospitals, factories, communities, etc., which can greatly save the cost of laying network lines. Of course, the network access device can also access a cellular signal of 6G or a higher level, which is not limited in this embodiment.
The communication interface includes, but is not limited to, a USB (Universal Serial Bus, universal serial bus) interface, a lightning interface and a firewire interface. The cellular communication device is provided with a communication interface matched with the communication interface. In an instance, the communication interface may be a pluggable communication interface, such as a hot plug communication interface.
The cellular communication device includes a cellular communication module. The cellular communication module is configured to communicate with the base station. Specifically, the cellular communication module is configured to communicate with a subscriber identity card (SIM card) and the base station.
The concrete implementation of the above-mentioned network access device 11 and the cellular communication module 12 and the interaction process between them will be described in detail in the following embodiments.
In the above 101, the cellular communication device includes a cellular communication module. In an instance, the cellular communication device may further include a SIM card slot connected with the cellular communication module, and the SIM card slot is used for inserting an external SIM card. The connection between the SIM card slot and the cellular communication module may include communication connection and power connection. The cellular communication module supplies power to the SIM card inserted in the SIM card slot through the power connection. In practical application, a user may first insert the SIM card into the SIM card slot in the cellular communication device, and then detachably connect the cellular communication device to the communication interface of the network access device.
In another instance, the cellular communication device may further include a virtual SIM card or an embedded SIM card communicating with the cellular communication module. In this embodiment, the virtual SIM card or the embedded SIM card is integrated with the cellular communication device.
In the above two embodiments, the SIM card is provided on the side of the cellular communication device. Of course, the SIM card may also be provided on the side of the network access device. Specifically, the network access device is further provided with at least one SIM card slot, and the at least one SIM card slot is in one-to-one correspondence with the at least one communication interface, where each SIM card slot in the at least one SIM card slot is connected with a corresponding communication interface. In practical application, the SIM card inserted in the SIM card slot communicates with the cellular communication device connected with the communication interface opposite to the SIM card slot.
In the above 101, the at least one communication interface includes a first communication interface. The first communication interface is any one of the at least one communication interface.
In an achievable solution, whether the first communication interface is detachably connected with an external cellular communication device may be detected in the following way: the processor may transmit first detection information to the first communication interface at regular intervals, and if first response information corresponding to the first detection information is received through the first communication interface, it is determined that an external cellular communication device is detachably connected with the first communication interface. A corresponding relationship between the first detection information and the first response information may be pre-stored in the network access device.
In the above 102, according to the detection result of the above 101, a non-idle communication interface which is detachably connected with an external cellular communication device in the at least one communication interface can be determined, and the cellular communication device detachably connected with the non-idle communication interface is determined as an available cellular communication device.
The number of the above-mentioned non-idle communication interface may be at least one, which is one or more. Accordingly, the number of the available cellular communication device is at least one, which is one or more.
In the above 103, the aggregation link refers to a link formed by combining a plurality of sub-links established between the network access device and the target server. The aggregation link includes a first sub-link established between the network access device and the target server based on an available cellular communication device, that is, the plurality of sub-links include the first sub-link. The first sub-link is established based on the cellular network accessed by the available cellular communication device.
The number of the available cellular communication device may be at least one, and accordingly, the aggregation link includes a first sub-link established between the network access device and the target server based on each cellular communication device in at least one cellular communication device. When the number of the available cellular communication device is one, the number of the first sub-link is one; when the number of the available cellular communication device is multiple, the number of the first sub-link is multiple.
In practical application, the aggregation link (or the multiple sub-links) may include not only the first sub-link, but also a second sub-link established between the network access device and the target server based on a wired communication module on the network access device, where the wired communication module is used for providing communication based on a wired network for the network access device. Specifically, the network access device is further provided with a wired wide area network interface; the wired wide area network interface is connected with the wired communication module, and when the wired wide area network interface is plugged with a network cable of a wired network, the wired communication module can provide communication based on the wired network for the network access device. That is, the second sub-link is based on the wired network accessed by the wired communication module.
In an achievable solution, the network access device may further include a wired wide area network interface. The processor is further configured to:
That is, the first sub-link is established based on the cellular network accessed by the cellular communication device, and the second sub-link is established based on the wired network.
In the above 103, “establish, based on the available cellular communication device, a first sub-link for data transmission between the network access device and the target server” is specifically: transmit a link establishment request to the available cellular communication device; the available cellular communication device transmits the link establishment request to the target server through the cellular network that it accesses, so as to establish the first sub-link between the network access device and the target server. In practical application, after the link establishment request is received, the target server may return a link establishment response message to the cellular communication device, and the cellular communication device transmits the link establishment response message to the processor, thus completing the establishment of the first sub-link.
In an instance, the available cellular communication device can automatically perform the operation of accessing the cellular network after detecting that it is detachably connected with the communication interface of the network access device. The specific access process may include: cell search, system information transmission and random access, etc. The specific implementation process of each stage can be found in the prior art and will not be described in detail here.
In another instance, the processor may transmit a network access request to the available cellular communication device; and the available cellular communication device performs the operation of accessing the cellular network after receiving the network access request.
It should be supplemented that the target server may be a service node in a content distribution network; and after startup, the network access device may transmit an aggregate link request to a scheduling center in the content distribution network. After the aggregation link request is received, the scheduling center selects a service node from the content distribution network as the target server according to a preset scheduling strategy, and transmits address information of the target server, such as the IP address, to the network access device. The network access device can subsequently establish an aggregation link with the target server according to the address information of the target server.
Of course, the address information of the target server may be stored in the network access device in advance, for example, the address information of the target server may be configured in a memory of the network access device by default before leaving the factory.
In the technical solution according to the embodiment of the present application, the network access device is provided with several communication interfaces for detachable connection with external cellular communication devices. That is to say, there is no need for a built-in cellular communication module in the network access device, and only several communication interfaces for detachable connection with external cellular communication devices need to be reserved. In this way, by providing cellular communication devices with various network standards, it can be realized that one kind of network access device can meet the different networking requirements of various customers in various occasions.
Optionally, the processor is further configured to:
In the above 104, the list of the available cellular communication device may record device information of the available cellular communication device and/or interface information of the communication interface to which the available cellular communication device is connected. The device information is used to uniquely identify the corresponding available cellular communication device; the interface information is used to uniquely identify the corresponding communication interface. The device information may include, but is not limited to, name and identification information. The interface information may include an interface number. For example, the network access device is provided with three communication interfaces, which may be numbered in advance, such as number 1, number 2and number 3.
In the above 105, when the data to be transmitted is received from the terminal device, the data to be transmitted may be distributed to each available cellular communication device recorded in the list of the available cellular communication device, so that each available cellular communication device transmits the data the available cellular communication device is responsible for transmission to the target server through the respective corresponding first sub-link in the aggregation link.
In an instance, a plurality of available cellular communication devices are recorded in the list of the available cellular communication device, and the data to be transmitted may be distributed to the plurality of available cellular communication devices recorded in the list of the available cellular communication device, so that the plurality of available cellular communication devices transmits the data the plurality of available cellular communication devices are respectively responsible for transmission to the target server through the respective corresponding first sub-links in the aggregation link.
In another instance, at least one available cellular communication device is recorded in the list of the available cellular communication device. In addition, the network access device is further provided with a wired communication module, where the wired communication module has been connected to the wired network. The data to be transmitted may be distributed to the at least one available cellular communication device recorded in the list of the available cellular communication device and the wired communication module provided on the network access device, so that each available cellular communication device transmits the data the available cellular communication device is responsible for transmission to the target server through the respective corresponding first sub-link in the aggregation link, and the wired communication module transmits the data the wired communication module is responsible for transmission to the target server through the second sub-link in the aggregation link.
In practical application, the user can insert a new cellular communication device into an idle communication interface on the network access device at any time according to actual needs, so as to increase the overall bandwidth of the aggregation link. Specifically, the processor is further configured to:
In the above 106, in an instance, interface information of a communication interface to which an available cellular communication device is connected is recorded in the list of the available cellular communication device. Therefore, according to the interface information of the communication interface to which the available cellular communication device is connected recorded in the list of the available cellular communication device, a non-idle communication interface and an idle communication interface can be determined from the at least one communication interface.
In the above 107, when it is detected that the idle communication interface is detachably connected with an external cellular communication device, it means that a new cellular communication device is connected with the idle communication interface, so it is necessary to update the aggregation link between the network access device and the target server based on the cellular communication device detachably connected with the idle communication interface. Specifically, the aggregation link between the network access device and the target server is updated based on the cellular communication device recorded in the list of the available cellular communication device and the cellular communication device detachably connected with the idle communication interface.
In an achievable solution, a new first sub-link may be established between the network access device and the target server based on the cellular communication device detachably connected with the idle communication interface, which is equivalent to adding a new first sub-link in the aggregation link between the network access device and the target server, and the original sub-link in the aggregation link remains unchanged.
In the above 108, a relevant record of the cellular communication device detachably connected with the idle communication interface may be added to the list of the available cellular communication device, for example, device information of the cellular communication device detachably connected with the idle communication interface and/or interface information of the idle communication interface may be added to the list of the available cellular communication device.
In this way, when there is new data to be transmitted later, the processor of the network access device performs data distribution or load balancing according to the updated list of the available cellular communication device, so as to ensure that the newly added cellular communication device can realize data transmission.
Optionally, the processor is further configured to:
When it is detected that the cellular communication device detachably connected with the non-idle communication interface has been detached, the record about the detached cellular communication device may be deleted in the list of the available cellular communication device, for example, the device information of the detached cellular communication device and/or the interface information of the non-idle communication interface may be deleted; alternatively, the record about the detached cellular communication device may be marked as detached in the list of the available cellular communication device.
In this way, when there is new data to be transmitted later, the processor of the network access device performs data distribution or load balancing according to the updated list of the available cellular communication device, so as to avoid the problem of data loss caused by distributing the data to the detached cellular communication device.
In an instance, “distribute data to be transmitted to each available cellular communication device recorded in the list of the available cellular communication device when the data to be transmitted is received from a terminal device, for transmission to the target server by each available cellular communication device through the aggregation link between the network access device and the target server” in the above 105 may be specifically implemented by adopting the following steps:
The aggregation link between the network access device and the target server includes the sub-link corresponding to the available cellular communication device recorded in the list of the available cellular communication device.
In the above 1051, in practical application, a network speed V of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device may be acquired by adopting a network speed measurement algorithm test; a network delay T of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device may be acquired by adopting a network delay algorithm test; and/or, a network jitter D of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device may be acquired by adopting a network jitter algorithm test.
A network quality Q of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device may be determined according to the network speed V, the network delay T and/or the network jitter D of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device.
In an achievable solution, the network quality Q of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device may be determined according to the network speed V, the network delay T and the network jitter D of the first sub-link corresponding to each available cellular communication device recorded in the list of the available cellular communication device.
For example, Q=xV+yT+zD, where the sum of x, y and z is 1. The specific numerical values of x, y and z may be set according to actual needs, which is not specifically limited in the embodiment of the present application.
In the above 1052, in an instance, the transmission amount allocated to the first sub-link corresponding to each available cellular communication device is determined according to the link quality and the total amount of data to be transmitted, where the better the link quality, the greater the allocated transmission amount. The data to be transmitted is distributed to each available cellular communication device recorded in the list of the available cellular communication device according to the transmission amount allocated to the first sub-link corresponding to each available cellular communication device.
Considering the practical application, users are likely to use two or more SIM cards of the same operator at the same time. If the cellular communication devices connected with these two or more SIM cards independently select the cell to be accessed, there will be a problem that the cell with the strongest signal scanned by the cellular communication devices connected with the two or more SIM cards of the same operator in the same place is usually the same, that is, the cellular communication devices connected with the two or more SIM cards of the same operator will access the same cell after selecting preferentially, that is, the cellular communication devices connected with the two or more SIM cards of the same operator will access the same base station. Once this base station fails, the whole network access device will not be able to provide network access for terminal users, and the availability or reliability will be poor.
In order to improve the availability or reliability, the processor in the network access device may decide which cell each cellular communication device accesses, so that the cellular communication devices connected with the two or more SIM cards of the same operator can be actively connected to different base stations of the same operator in a decentralized manner. In this way, when one of the base stations fails, the network access device can still improve the network access capability for the user terminal based on other base stations, which ensures the reliability of communication. Specifically, there are a plurality of available cellular communication devices; and the processor is further configured to:
In the above 111, the wireless network standard refers to the type of the wireless network, which may include, but is not limited to: 2G, 3G, 4G, 5G, Cat1 and Cat4. The operator information may include, but is not limited to: China Mobile, China Telecom and China Mobile. Different cellular communication devices may support different wireless network standards, and similarly, different subscriber identity cards (SIM cards) may support different operator information.
In an instance, the operator information supported by different cellular communication devices may be different, so in the above 111, the operator information supported by each available cellular communication device may further be acquired.
In the above 112, a scan command may be sent to each available cellular communication device in the plurality of available cellular communication devices, so that each available cellular communication device can acquire cell information of an available cell through scanning; each available cellular communication device acquires the cell information of the available cell through scanning and then transmits it to the processor of the network access device.
The cell information may include but is not limited to: base station information, wireless network standard, effective band (Band) and operator information.
In the above 113, cell access indication information of each available cellular communication device in the plurality of available cellular communication devices is determined according to the first acquisition result and the second acquisition result.
Specifically, it is determined whether there are two or more SIM cards belonging to the same operator according to the operator information supported by the subscriber identity card that each available cellular communication device in the plurality of available cellular communication devices is connected with. If there are two or more SIM cards belonging to the same operator, the target cell of the available cellular communication device connected with each SIM card in the two or more SIM cards is determined according to the wireless network standards supported by the available cellular communication devices connected with the two or more SIM cards and the cell information of the available cells obtained through scanning; the cell access indication information of the available cellular communication device connected with each SIM card in the two or more SIM cards is determined according to the cell information of the target cell of the available cellular communication device connected with each SIM card in the two or more SIM cards. The cell access indication information includes the cell information of the target cell, where the cell information of the target cell is used to instruct the corresponding available cellular communication device to access the target cell. The cell access indication information of the available cellular communication device connected with each SIM card of the two or more SIM cards is used to instruct the available cellular communication devices connected with the two or more SIM cards to access different cells, and the base stations corresponding to the different cells are different.
For example, the plurality of available cellular communication devices include a first available cellular communication device and a second available cellular communication device, the SIM cards connected with the first available cellular communication device and the second available cellular communication device belong to China Mobile. The wireless network standards supported by the first available cellular communication device are 4G and 5G, and the available cells obtained through scanning are: 4G cell of China Mobile and 5G cell of China Mobile. The wireless network standard supported by the second available cellular communication device is 4G, and the available cells obtained through scanning are: 4G cell of China Mobile and 5G cell of China Mobile. Therefore, it can be determined that the cell access indication information of the second available cellular communication device is used to instruct the second available cellular communication device to access the 4G cell of China Mobile and the cell access indication information of the first available cellular communication device is used to instruct the first available cellular communication device to access the 5G cell of China Mobile.
For another example, the plurality of available cellular communication devices include a first available cellular communication device and a second available cellular communication device, the SIM cards connected with the first available cellular communication device and the second available cellular communication device belong to China Mobile. The wireless network standards supported by the first available cellular communication device are 4G and 5G, and the available cells obtained through scanning are: 4G cell of China Mobile and 5G cell of China Mobile. The wireless network standards supported by the second available cellular communication device are 4G and 5G, and the available cell obtained through scanning is: 5G cell of China Mobile. Therefore, it can be determined that the cell access indication information of the second available cellular communication device is used to instruct the second available cellular communication device to access the 5G cell of China Mobile, and the cell access indication information of the first available cellular communication device is used to instruct the first available cellular communication device to access the 4G cell of China Mobile.
In practical application, if there is a SIM card belonging to only one operator in the SIM cards connected with the plurality of available cellular communication devices, the available cell with the strongest signal in the available cells obtained through scanning by the available cellular communication device connected with the SIM card belonging to only one operator may be determined as the target cell corresponding to the available cellular communication device.
In the above 114, the cell access indication information of each available cellular communication device of the plurality of available cellular communication devices is sent to the corresponding available cellular communication device, so that each available cellular communication device accesses the corresponding cell according to the received cell access indication information. Each available cellular communication device accesses the target cell indicated by the cell access indication information according to the received cell access indication information.
That is to say, in the embodiment of the present application, the processor of the network access device makes the overall decision on the cell that each available cellular communication device needs to access, instead of deciding by each available cellular communication device itself. By adopting the solution provided in the embodiment of the present application, the plurality of cellular communication devices can be actively and dispersedly connected with different cells, namely different base stations.
