Techniques for geographic information for wireless networks are described. According to various embodiments, a connectivity module on a mobile device receives geographic position information for a mobile device from another functionality of the mobile device and independent of a query by the connectivity module for the information. The connectivity module retrieves the geographic position information locally on the device, and utilizes the geographic position information to cause various actions to be performed. For instance, the connectivity module utilizes the geographic position information to identify a wireless network at a particular geographic region, and to cause a wireless scan to be initiated to detect the wireless network.
The detailed description is described with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different instances in the description and the figures may indicate similar or identical items.
Overview
Techniques for geographic information for wireless networks are described. According to various implementations, a connectivity module on a mobile device registers to receive a notification when geographical position information is available on the mobile device. For instance, the connectivity module registers to receive a wake event to wake the connectivity module from an inactive state when the geographic position information is available. Generally, the connectivity module represents a functionality that manages various wireless connectivity tasks for a mobile device.
According to one or more implementations, a connectivity module receives geographic position information for a mobile device independent of a query for the information. For instance, when another functionality of the mobile device (e.g., an application and/or service) retrieves geographic position information, the connectivity module is notified that the information is available locally on the device. According to various implementations, the geographic position information corresponds to an estimated current location of the mobile device, and/or a projected future location estimated based on trajectory and velocity information for the mobile device. The connectivity module retrieves the geographic position information locally on the device, and utilizes the geographic position information to cause various actions to be performed.
For instance, the connectivity module utilizes the geographic position information to identify and select a wireless network that is available at a location that corresponds to the geographic position information. The connectivity module causes a network scan to be performed to identify wireless signal from the wireless network. For instance, the connectivity module schedules a network scan to be performed to detect the wireless network. Alternatively or additionally, the connectivity module instructs a wireless functionality of a mobile device to activate its wireless radio and scan for the wireless network.
According to various implementations, a connectivity module of a mobile device is maintained in an inactive state until a wake event is received in response to geographic position information being available locally on the mobile device. Further, a wireless functionality of a mobile device (e.g., a wireless radio) is maintained in an inactive state (e.g., off) until the connectivity module identifies an available wireless network at a particular location, and causes the wireless functionality to activate and scan for the wireless network. Thus, various resources of a mobile device are conserved, such as battery life, processing resources, wireless communication resources, and so forth.
For instance, instead of causing a wireless radio to perform open scanning in an attempt to identify an available wireless network, the wireless radio is kept in an inactive state until geographical position information is received and correlated to a known available wireless network at a particular location. At such point, the wireless radio is activated to search for the known available wireless network. Various other details of the techniques discussed herein are provided below.
According to various implementations, preparation for connectivity to a wireless network can occur ahead of time, such as prior to the wireless network being detected and/or prior to the wireless network being in-range. For instance, a network profile is loaded for a wireless network that is identified based on geographic position information and prior to the wireless network being detected. Generally, the network profile includes connectivity information such as a network identifier for the wireless network, authentication information for the wireless network, and so forth. Accordingly, the connectivity information is made available such that when the wireless network is detected (e.g., based on a wireless radio scan), the connectivity information is readily available. Thus, connection time and system resource usage are reduced for the connection process.
In the following discussion, an example environment is first described that is operable to employ techniques described herein. Next, a section entitled “Example Procedures” describes some example procedures for geographic information for wireless networks in accordance with one or more embodiments. Finally, a section entitled “Example System and Device” describes an example system and device that are operable to employ techniques discussed herein in accordance with one or more embodiments.

For instance, the connectivity module 110 performs various aspects of techniques for geographic information for wireless networks discussed herein.
According to various implementations, the network DB 112 is representative of functionality to retrieve and store network information about the different networks 120. The network DB 112, for instance, stores network identifiers for individual networks 120, such as service set identifiers (SSID) and other types of network identifiers.
The network DB 112 further correlates individual networks 120 with different location information, such as geographical locations at which the client device 102 may connect to the different networks 120.

The network table 200 includes a network identifier (ID) column 202, an authentication information column 204, an authentication protocol column 206, a geographic range column 208, and a network preference column 210. These examples of different network information are presented for purpose of example only, and it is to be appreciated that various other types of network information may be tracked and leveraged in accordance with the implementations disclosed herein.
Generally, the different rows in the network table 200 represent network profiles for different wireless networks. For instance, a network profile 212 represents a network profile for a wireless Network ABC. Examples of information included in the different network profiles is now discussed.
The network ID column 202 includes identifiers for different wireless networks, such as for the networks 120. Various types of identifiers may be employed, such as network names, network SSIDs, internet protocol (IP) addresses, and so forth. Generally, the individual rows of the network table 200 correspond to network profiles for different networks identified in the network ID column 202.
The authentication information column 204 includes authentication information for different networks, such as network keys, passwords, user names, and so forth. The authentication protocols column 206 identifies authentication protocols utilized by different networks, and whether particular networks utilize authentication. For instance, some networks are open and thus may not utilize an authentication protocol.
The geographic range column 208 includes geographic information that identifies geographic regions for the different wireless networks. For instance, the range column 208 includes GPS coordinates and/or other geographic information that describes geographic regions in which connectivity to particular wireless networks is available. As an example, the “ABC_Geographic Coordinates” for the Network ABC may define boundaries of a geographic region within which connectivity to the Network ABC is available and/or is within acceptable signal strength and/or signal quality.
The network preference column 210 identifies whether certain wireless networks are preferred over others. For instance, a particular geographic region may have multiple available wireless networks identified in the network table 200. In such as case, an available network identified in the preference column 210 as being preferred is given preference for network connectivity for a device (e.g., the client device 102) over another available network that is not preferred.
Network preference may be based on various factors, such as historic signal strength (e.g., a network with higher historic signal strength is preferred over a network with lower historic signal strength), historic signal quality (e.g., a network with higher historic signal quality is preferred over a network with lower historic signal quality), cost of connecting to the network (e.g., a network with lower connection cost (e.g., price/rate to connect) is preferred over a network with higher connection cost), whether a network is known to be secure (e.g., a more secure network is preferred over a less secure network), and so forth.
In at least some implementations, network information stored in the network table 200 is retrieved from the network information service 122. For instance, the client device 102 may query the network information service 122 for network information. Alternatively or additionally, the network information service 122 may push network information down to the client device, such as independent of a query by the client device 102 for the network information. Accordingly, in at least some implementations, the connectivity module 110 may purge old data (e.g., stale network information) from the network table 200, and may update the network table 200 with current network information received from the network information service 122.
Having described an example environment in which the techniques described herein may operate, consider now some example procedures in accordance with one or more implementations.
This section describes some example procedures for performing different aspects of techniques for geographic information for wireless networks discussed herein. The procedures described herein may be used separately or in combination with each other, in whole or in part. These procedures are shown as sets of operations (or acts) performed, such as through one or more entities or modules, and are not necessarily limited to the order shown for performing the operation. The example procedures may be employed in the environment 100 of
Step 300 registers to receive a notification that geographic position information is available on a device. For instance, the connectivity module 110 registers with a functionality of the client device 102 (e.g., the operating system 104) to receive notifications when geographical position information is locally available on the client device 102. In at least some implementations, the registering includes requesting that a wake event being communicated to the connectivity module 110 to wake the connectivity module 110 from an inactive state to an active state such that the connectivity module 110 can retrieve geographic position information and cause an action to be performed based on the geographic position information. Thus, the wake event may be configured as an indication that geographic position information is available locally on a device.
Step 302 receives an indication that geographic position information is available on a device. The connectivity module 110, for instance, receives a notification from a functionality of the client device 102 (e.g., the operating system 104) that geographic position information for the client device 102 is available. In at least some implementations, the notification takes the form of a wake event that wakes the connectivity module 110 from an inactive state and notifies the connectivity module that the geographic position information is available.
According to various implementations, geographic position information is retrieved on the client device 102 based on a request from a functionality other than the connectivity module 110. For instance, an application 114 may request location information to determine a geographic location of the client device 102, a direction of movement of the client device 102, a rate of movement of the client device 102, and so forth. In response to the request, the client location module 108 queries a position information system 118 for geographic position information for the client device, such as GPS coordinates, a geographic place name, a physical address, and so forth. The position information system 118 returns the geographic position information to the client device 102 such that the geographic position information is available locally to different functionalities of the client device 102, such as the connectivity module 110.
Accordingly, in at least some implementations, the connectivity module 110 does not initiate direct requests for geographic position information, but is configured to retrieve and utilize geographic position information that is retrieved and made locally available by other functionalities. For instance, the indication that the geographical position information is available is received by the connectivity module 110 independent of a query by the connectivity module 110 for geographical position information.
Step 304 retrieves the geographic position information from a location that is local to the device. For instance, the connectivity module 110 receives the geographic position information from another functionality of the client device 102, such as the client location module 108, the operating system 104, and so forth.
Step 306 performs an action in response to retrieving the geographic position information. Various actions are performable in relation to the selected wireless network, examples of which are detailed in the following procedures.
Step 308 transitions to an inactive state until further geographic position information is received. For instance, after performing and/or initiating various actions in response to retrieving the geographic position information, the connectivity module 110 transitions to an inactive state until a notification of further geographic position information is received. In an inactive state, the connectivity module 110 may be configured to receive wake events to become active, but may not proactively initiate other actions.
As illustrated, the procedure may return to step 302 when an indication of further geographical position information is received, such as a wake event communicated to the connectivity module 110.
Step 400 ascertains whether a device is currently connected to a wireless network. The connectivity module 110, for example, queries the wireless module 106 and/or the operating system 104 to ascertain whether the client device 102 is currently connected to a wireless network.
If the device is not currently connected to a wireless network (“No”), step 402 ascertains whether a wireless network is available at a location identified by geographic position information. For instance, the geographic position information represents position information that is retrieved as described above with reference to
Alternatively or additionally, the connectivity module 110 queries the network information service 122 with the geographic position information. For instance, the connectivity module 110 communicates the geographic position information to the network information service 122, which returns information indicating whether a wireless network is available and if so, information about the available wireless network(s). The connectivity module 110 stores the information about the available wireless network as part of the network DB 112. Thus, in at least some implementations, the client device 102 need not maintain comprehensive wireless network information locally, and may leverage the network information service 122 to provide such information.
If a wireless network is not available at the location (“No”), step 404 maintains a wireless radio of the device in an inactive state. For instance, one or more of the wireless radios 116 of the client device 102 are maintained in an inactive (e.g., off) state. According to one or more implementations, the procedure may return to step 402 as new geographic position information is received to ascertain whether a wireless network is available. For instance, as the client device 102 is moving (e.g., with a user that is traveling), new geographic position information is received indicating different locations of the client device 102.
If a wireless network is available at the location (“Yes”), step 406 selects a wireless network that is available at the location identified by geographic position information. The connectivity module 110, for example, searches the network DB 112 with the geographic position information to identify a wireless network that is available at a location (e.g., a geographic location) identified by the geographic position information. Alternatively or additionally, the connectivity module 110 queries the network information service 122 with the geographical position information, and the network information service 122 returns information identifying one or more available wireless networks, and attributes of the wireless networks.
In at least some implementations, a network profile for the selected wireless network is loaded to enable connection to the wireless network. For instance, the connectivity module 110 retrieves a network profile from the network DB 112, and provides information from the network profile to a functionality such as the wireless module 106 and/or the operating system 104. As referenced above, the network profile includes various information about the selected network, such as a network ID, authentication information for connecting to the wireless network, and so forth. Thus, an entity involved in negotiating a connection to the wireless network utilizes information from the network profile to establish a connection to the wireless network.
According to various implementations, the network profile for the selected network is loaded by the connectivity module 110 prior to the network being detected and/or prior to the client device 102 being in connectivity range of the network. Thus, preparation for upcoming connectivity to a wireless network can occur to expedite the connectivity process.
Step 408 schedules a network scan to detect the wireless network. The connectivity module 110, for example, notifies the wireless module 106 to initiate a network scan (e.g., via one or more of wireless radios 116) to detect the selected wireless network. In at least some implementations, the notification instructs the wireless module 106 to initiate the network scan immediately, or at a future time.
For instance, consider a scenario where the client device 102 is in motion, such as with a user that is traveling. Accordingly, the connectivity module 110 ascertains based on the geographic position information that the client device 102 is not currently in range of the wireless network. However, based on a current trajectory and speed of the user, the connectivity module 110 estimates that the client device 102 will likely be in range within a specific period of time. Accordingly, the connectivity module 110 schedules the network scan to be initiated after the specific period of time elapses and/or within a particular time interval. Battery power is thus conserved by delaying the network scan until the client device 102 is in range of a known wireless network. Accordingly, in at least some implementations, scheduling the network scan occurs while the network is not currently detected by the device, such as while a wireless radio of the device is in an inactive state.
Step 410 causes a wireless radio of the device to transition from an inactive state to an active state to scan for the wireless network. In at least some implementations, causing the wireless radio to transition from the inactive state to the active state is a result of the scheduled network scan.
Step 412 retrieves authentication information for the wireless network. Examples of authentication information are detailed above, and generally include one or more authentication factors that may be used to authenticate the client device 102 for access to a particular wireless network. The authentication information, for instance, is retrieved from the network table 200 and/or the network information service 122.
Step 414 communicates the authentication information to be used to connect to the wireless network. For instance, the connectivity module 110 communicates the authentication information to the wireless module 106. The wireless module 106 then communicates the authentication information to the selected wireless network to authenticate and establish wireless connectivity with the selected wireless network. For instance, the wireless module performs a network association procedure to associate with the wireless network such that the client device 102 transmits and receives data wirelessly via the wireless network.
Returning to step 400, if the device is currently connected to a wireless network (“Yes”), step 416 ascertains whether the current wireless network is a preferred wireless network. The connectivity module 110, for instance, compares a network ID for the current wireless network to the network DB 112 to ascertain whether the current wireless network is identified as a preferred wireless network. If the current wireless network is a preferred wireless network (“Yes”), step 418 ascertains that the connection to the current wireless network is to be maintained.
If the current wireless network is not a preferred wireless network (“No”), step 420 ascertains whether a preferred wireless network is available at a location identified by the geographic position information. The connectivity module 110, for instance, searches the network DB 112 and/or queries the network information service 122 with the geographic position information to ascertain whether a preferred wireless network is available at the location. If a preferred wireless network is not available at the location (“No”), the method returns to step 418.
If a preferred wireless network is available at the location (“Yes”), step 422 causes the device to switch from the current wireless network to the preferred wireless network. For instance, the connectivity module 110 instructs the wireless module 106 to disconnect from the current wireless network and to connect with the preferred wireless network. In at least some implementations, the connectivity module 110 retrieves authentication information for the preferred wireless network from the network DB 112 and/or the network information service 122, and communicates the authentication information to the wireless module 106 to be used to connect to the preferred wireless network. Thus, the wireless module 106 proceeds with disconnecting from the current wireless network, and connecting to the preferred wireless network.
Step 500 identifies a wireless network based on geographic position information. For instance, the connectivity module 110 searches the network DB 112 with the geographic position information to identify a wireless network that is capable of providing wireless connectivity in a geographic region identified by the geographic position information. Alternatively or additionally, the connectivity module 110 queries the network information service 122 with the geographic position information and requests information for one or more wireless networks capable of providing wireless connectivity in a geographic region identified by the geographic position information.
In at least some implementations, the wireless network is identified as a wireless network that is currently in-range of the client device 102. For instance, the geographic position information corresponds to a current location of the client device 102. In another implementation, the wireless network is identified as a wireless network that will be in-range of the client device 102 at a future time. As an example, consider that the client device 102 is in motion, such as with a user that is traveling. Accordingly, the geographic information may include speed and trajectory information for the client device 102 which can be used to identify one or more wireless networks that are predicted to be in range at a future time. The future time may be measured in various units, such as seconds, minutes, and so forth.
Step 502 prepares to connect to the wireless network. The connectivity module 110, for instance, loads connectivity information for the wireless network from a network profile for the wireless network located in the network DB 112. Alternatively or additionally, the connectivity module 110 retrieves connectivity information from the network information service 122. Generally, the connectivity information includes information to enable a wireless connection with the wireless network to be established. Examples of connectivity information are detailed above, and generally include a network ID, authentication information, and so forth.
According to various implementations, the connectivity module 110 provides the connectivity information to a functionality responsible for negotiating a connection to the wireless network, such as the wireless module 106, the operating system 104, and so forth.
Step 504 causes a connection to the wireless network to be established. For example, the connectivity module 110 signals the wireless module 106 that the client device 102 is in-range of the wireless network, and thus the wireless module 106 is to scan for the wireless network. Further, the connectivity module 110 notifies the wireless module 106 to utilize the connectivity information to connect to the wireless network.
Alternatively or additionally, the connectivity module 110 may notify the wireless module 106 that the client device will be in-range of the wireless network at a future time, such as in seconds, minutes, at a particular clock time, and so forth Thus, the wireless module 106 may schedule a scan for the wireless network to be performed at the future time and utilizing the connectivity information.
Thus, implementations discussed herein enable preparations for connectivity to a wireless network to occur in advance, such as before the wireless network is detected and/or before the wireless network is in-range. Accordingly, when the wireless network is detected, the client device 102 is already prepared to connect to the network, thus reducing connection time and resource usage during the connection process.
Step 600 ascertains that multiple wireless networks are identified as being available at a particular location. The connectivity module 110, for instance, searches the network DB 112 and/or queries the network information service 122 with geographical position information, and ascertains that multiple wireless networks are available at a location identified by the geographical position information.
Step 602 selects a network of the multiple wireless networks based on the network being a preferred network. Thus, a particular wireless network may be selected from the multiple wireless networks based on network preference, e.g., a preferred wireless network is selected over a non-preferred wireless network. Example factors considered in determining whether a wireless network is preferred are discussed above with reference to the network table 200.
Step 700 ascertains that network information on a device is for one or more networks that are not available at a current location of the device. For instance, the connectivity module 110 ascertains that network information is stored on the client device 102 for one or more wireless networks that are not available at a current geographic location of the client device 102. The network information, for instance, corresponds to wireless networks that were available at one or more previous (e.g., historic) locations of the client device 102. Thus, the network information may be considered “stale” in that it is not relevant to a current geographic location of the client device 102.
Step 702 deletes the network information from the device. The connectivity module 110, for instance, causes the stale network information to be deleted from the network DB 112. Accordingly, data storage space of the client device 102 is conserved by freeing storage space occupied by stale network information.
Step 800 receives further geographic position information. The connectivity module 110, for instance, retrieves further geographic position information that is different than previously-received geographic position information. According to various implementations, the geographic position information indicates that the client device 102 has moved from a previous geographic location to a different geographic location.
Step 802 ascertains that a suitable wireless network is not available at a location identified by the further geographic position information. For example, the connectivity module 110 searches the network DB 112 and/or queries the network information service 122 with the further geographic position information, and ascertains that a suitable wireless network is not available. In at least some implementations, this indicates that a wireless network is not available at the location.
Alternatively, this indicates that a wireless network is available, but that the wireless network does not meet one or more connectivity criteria for identifying the wireless network as being suitable for connectivity. Examples of such connectivity criteria include minimum network security procedures, minimum signal strength and/or signal quality, a maximum connectivity cost (e.g., a price for network connectivity), and so forth. Thus, a wireless network may be available, but may be determined to be unsuitable due to failure of the wireless network to meet one or more connectivity criteria.
Step 804 causes a wireless radio to transition from an active state to an inactive state. The connectivity module 110, for instance, causes one or more of the wireless radios 116 to transition to an inactive state responsive to ascertaining that a suitable wireless network is not available. Thus, battery power is conserved by inactivating a wireless radio when suitable wireless networks are not available. Otherwise, a wireless radio may continually scan for wireless networks, which reduces battery life of a device.
According to various implementations, the procedure may return to step 302 of
Thus, techniques discussed herein provide multiple performance optimizations for wireless enabled devices. For instance, a functionality configured to manage wireless connectivity (e.g., the connectivity module 110) is maintained in an inactive state until geographic position information is available, thus conserving power and processing resources that would be used to maintain the functionality in an active state. As another example, a scan for an available wireless network is scheduled based on knowledge of available wireless networks at a particular geographic location, thus preventing open scanning in locations where suitable wireless networks are not present. As yet another example, a device's wireless radio may be kept in an inactive state until the device is at a geographic location known to have one or more suitable wireless networks.
Having discussed some example procedures, consider now a discussion of an example system and device in accordance with one or more embodiments.

Accordingly, software, hardware, or program modules and other program modules may be implemented as one or more instructions and/or logic embodied on some form of computer-readable storage media and/or by one or more hardware elements 910. The computing device 902 may be configured to implement particular instructions and/or functions corresponding to the software and/or hardware modules. Accordingly, implementation of modules as a module that is executable by the computing device 902 as software may be achieved at least partially in hardware, e.g., through use of computer-readable storage media and/or hardware elements 910 of the processing system. The instructions and/or functions may be executable/operable by one or more articles of manufacture (for example, one or more computing devices 902 and/or processing systems 904) to implement techniques, modules, and examples described herein.
As further illustrated in
In the example system 900, multiple devices are interconnected through a central computing device. The central computing device may be local to the multiple devices or may be located remotely from the multiple devices. In one embodiment, the central computing device may be a cloud of one or more server computers that are connected to the multiple devices through a network, the Internet, or other data communication link.
In one embodiment, this interconnection architecture enables functionality to be delivered across multiple devices to provide a common and seamless experience to a user of the multiple devices. Each of the multiple devices may have different physical requirements and capabilities, and the central computing device uses a platform to enable the delivery of an experience to the device that is both tailored to the device and yet common to all devices. In one embodiment, a class of target devices is created and experiences are tailored to the generic class of devices. A class of devices may be defined by physical features, types of usage, or other common characteristics of the devices.
In various implementations, the computing device 902 may assume a variety of different configurations, such as for computer 914, mobile 916, and television 918 uses. Each of these configurations includes devices that may have generally different constructs and capabilities, and thus the computing device 902 may be configured according to one or more of the different device classes. For instance, the computing device 902 may be implemented as the computer 914 class of a device that includes a personal computer, desktop computer, a multi-screen computer, laptop computer, netbook, and so on.
The computing device 902 may also be implemented as the mobile 916 class of device that includes mobile devices, such as a mobile phone, a wearable device, portable music player, portable gaming device, a tablet computer, a multi-screen computer, and so on. The computing device 902 may also be implemented as the television 918 class of device that includes devices having or connected to generally larger screens in casual viewing environments. These devices include televisions, set-top boxes, gaming consoles, and so on.
The techniques described herein may be supported by these various configurations of the computing device 902 and are not limited to the specific examples of the techniques described herein. For example, functionalities discussed with reference to the client device 102 and/or the network information service 122 may be implemented all or in part through use of a distributed system, such as over a “cloud” 920 via a platform 922 as described below.
The cloud 920 includes and/or is representative of a platform 922 for resources 924. The platform 922 abstracts underlying functionality of hardware (e.g., servers) and software resources of the cloud 920. The resources 924 may include applications and/or data that can be utilized while computer processing is executed on servers that are remote from the computing device 902. Resources 924 can also include services provided over the Internet and/or through a subscriber network, such as a cellular or Wi-Fi™ network.
The platform 922 may abstract resources and functions to connect the computing device 902 with other computing devices. The platform 922 may also serve to abstract scaling of resources to provide a corresponding level of scale to encountered demand for the resources 924 that are implemented via the platform 922. Accordingly, in an interconnected device embodiment, implementation of functionality described herein may be distributed throughout the system 900. For example, the functionality may be implemented in part on the computing device 902 as well as via the platform 922 that abstracts the functionality of the cloud 920.
