Referring now to the drawings, in which like numerals represent like elements throughout the several figures, example aspects of location-based WI-FI radio activation and deactivation for mobile devices will be presented.
Referring now to FIG. 1, aspects of an illustrative operating environment 100 for various concepts disclosed herein will be described. It should be understood that the operating environment 100 and the various components thereof have been greatly simplified for purposes of discussion. Accordingly, additional or alternative components of the operating environment 100 can be made available without departing from the embodiments described herein.
The operating environment 100 shown in FIG. 1 includes a mobile device 102. The mobile device 102 may be a cellular telephone, a smartphone, a mobile computer, a tablet computer, or the like. In the illustrated embodiment, the mobile device 102 includes a cellular radio 104 that facilitates wireless communication over a radio/air interface with a mobile telecommunications network 106. The illustrated mobile device 102 also includes a WI-FI radio 108 that facilitates wireless communication over a radio/air interface with a WI-FI network 110.
The mobile telecommunications network 106 includes one or more radio access networks (“RANs”). The mobile telecommunications network 106 can also include a wireless wide area network (“WWAN”), which may, in turn, include a circuit-switched core network (“CS CN”), a packet-switched core network (“PS CN”), and/or an IP multimedia subsystem (“IMS”) core network. The WWAN can utilize one or more mobile telecommunications technology standards to provide voice and/or data services via one or more RANs to a WWAN component of the mobile device 102 such as the cellular radio 104. The mobile telecommunications technology standards may include, but are not limited to, Global System for Mobile communications (“GSM”), Code Division Multiple Access (“CDMA”) ONE, CDMA2000, Universal Mobile Telecommunications System (“UMTS”), Long-Term Evolution (“LTE”), Worldwide Interoperability for Microwave Access (“WiMAX”), and/or the like.
A RAN can utilize various channel access methods (which may or may not be used by the aforementioned standards) including, but not limited to, Time Division Multiple Access (“TDMA”), Frequency Division Multiple Access (“FDMA”), CDMA, wideband CDMA (“W-CDMA”), Orthogonal Frequency Division Multiplexing (“OFDM”), Space Division Multiple Access (“SDMA”), and/or the like to provide an air interface to the mobile device 102. A RAN may be a GSM RAN (“GRAN”), a GSM EDGE RAN (“GERAN”), a UMTS Terrestrial Radio Access Network (“UTRAN”), an E-UTRAN, any combination thereof, and/or the like. The mobile device 102 can communicate with one or more RANs that utilize the same or different radio access technologies. As such, in some embodiments, the mobile device 102 is a multi-mode communications device.
Data communications can be provided by the mobile telecommunications network 106 using General Packet Radio Service (“GPRS”), Enhanced Data rates for Global Evolution (“EDGE”), the High-Speed Packet Access (“HSPA”) protocol family including High-Speed Downlink Packet Access (“HSDPA”), Enhanced Uplink (“EUL”) or otherwise termed High-Speed Uplink Packet Access (“HSUPA”), Evolved HSPA (“HSPA+”), LTE, and/or various other current and future wireless data access standards. The mobile telecommunications network 106 may be configured to provide voice and/or data communications with any combination of the above technologies. The mobile telecommunications network 106 may be configured to or adapted to provide voice and/or data communications in accordance with future generation technologies. The mobile device 102 may also initiate, receive, and/or maintain voice calls with one or more other devices (not shown). The mobile device 102 may also exchange Short Message Service (“SMS”) messages, email, and/or other messages with other devices.
The mobile telecommunications network 106 may be owned and/or operated by one or more mobile telecommunications carriers. In some implementations, the mobile telecommunications network 106 includes a mobile telecommunications carrier's network and one or more partner networks, such as networks owned and/or operated by one or more roaming partners of the mobile telecommunications carrier.
The WI-FI network 110 may operate in accordance with one or more Institute of Electrical and Electronic Engineers (“IEEE”) 802.11 standards such as IEEE 802.11a, 802.11b, 802.11g, 802.11n, and/or future 802.11 standard (referred to herein collectively as “WI-FI”). Draft 802.11 standards are also contemplated. The WI-FI network 110 can include one or more access points that provide a radio/air interface over which the mobile device 102 can send and/or receive data. In some implementations, an access point is a mobile device or other computing device that functions as a WI-FI hotspot. In some implementations, the mobile device 102 is configured to connect to the WI-FI network 110 via one or more secure connections, each of which may utilize an encryption technology such as, but not limited to, WI-FI Protected Access (“WPA”), WPA2, Wired Equivalent Privacy (“WEP”), and/or the like.
In some embodiments, the WI-FI network 110 is owned and/or operated by a mobile telecommunications carrier, which may be the same mobile telecommunications carrier that owns and/or operates the mobile telecommunications network 106. The mobile telecommunications carrier may partner with one or more businesses and/or other entities to provide one or more WI-FI access points in locations used to facilitate access to the WI-FI network 110 by mobile devices, such as the mobile device 102. In some other embodiments, the WI-FI network 110 is a WI-FI network operated by or for a business or other entity (e.g., a municipality) without the involvement of a mobile telecommunications carrier. In some other embodiments, the WI-FI network 110 is a user WI-FI network. For example, the WI-FI network 110 may be a WI-FI network 110 setup using one or more WI-FI routers in a home, workplace, or other location of a user of the mobile device 102.
The mobile device 102 can communicate with the mobile telecommunications network 106 and/or the WI-FI network 110 to access a data network 112. The data network 112 can be or can include a packet data network (“PDN”), an internet, the Internet, an intranet, some combination thereof, and/or the like. The mobile device 102 can access the data network 112 via the mobile telecommunications network 106 and/or the WI-FI network 110 to access content such as Websites, streaming media, online video games, downloadable content, and the like. The mobile device 102 can access the data network 112 via the mobile telecommunications network 106 and/or the WI-FI network 110 to conduct voice over Internet protocol (“VoIP”) calls, engage in messaging services, or engage in other communication services provided at least in part via the data network 112.
The mobile device 102 is illustrated in duplication to show the connectivity of the mobile device 102 to both the mobile telecommunications network 106 and the WI-FI network 110. In some implementations, the mobile telecommunications network 106 has a coverage area that encompasses at least a portion of the WI-FI network 110. The mobile device 102 therefore can be simultaneously connected to the mobile telecommunications network 106 and the WI-FI network 110. In the illustrated example, however, the mobile device 102 communicates with the mobile telecommunications network 106 via the cellular radio 104 in an activated or “ON” state, while the WI-FI radio 108 is in a deactivated or “OFF” state. Similarly, the mobile device 102 communicates with the WI-FI network 110 via the WI-FI radio 108 in an activated or “ON” state, while the cellular radio 104 is in a deactivated or “OFF” state. The activation or deactivation of the cellular radio 104 and/or the WI-FI radio 108 can be managed by or for a mobile telecommunications carrier that owns and/or operates the mobile telecommunications network 106. In this manner, the mobile telecommunications carrier can steer the mobile device 102 to connect to the WI-FI network 110 so as to conserve resources of the mobile telecommunications network 106. The selective activation and deactivation of the cellular radio 104 and/or the WI-FI radio 108 can also increase battery life of the mobile device 102.
Although the cellular radio 104 is shown as being in a deactivated or “OFF” state when connected to the WI-FI network 110, the cellular radio 104 alternatively may be in a low-power state in which the cellular radio 104 consumes less power than when in the activated or “ON” state, but more power than when in the deactivated or “OFF” state. Alternatively, the cellular radio 104 may be in an activated or “ON” state when connected to the WI-FI network 110. In this implementation, the mobile device 102 can send and/or receive voice calls or other non-data communications via a connection to the mobile telecommunications network 106 provided by the cellular radio 104, and conduct data communications such as Web browsing, music or video streaming, or the like via a connection to the WI-FI network 110 provided by the WI-FI radio 108.
The operating environment 100 also includes a WI-FI connection management system 114 (hereinafter “WI-FI CMS” in the drawings). The WI-FI connection management system 114 can communicate with the mobile telecommunications network 106 to provide instructions regarding whether or not the mobile device 102 should activate or deactivate the cellular radio 104 and/or the WI-FI radio 108. For example, when the mobile device 102 enters a coverage area provided by the WI-FI network 110, the WI-FI connection management system 114 can generate a trigger 116 that includes instructions useable by the mobile device 102 to activate the WI-FI radio 108, and send the trigger 116 to the mobile device 102 so as to instruct the mobile device 102 to activate the WI-FI radio 108. These instructions may additionally include instructions useable by the mobile device 102 to deactivate the cellular radio 104 or put the cellular radio 104 into another state such as a low-power state.
In some embodiments, the WI-FI connection management system 114 detects a utilization load of the WI-FI network 110. For example, one or more access points operating within the WI-FI network 110 can provide utilization load information to the WI-FI connection management system 114 upon request from the WI-FI connection management system 114 or periodically. The WI-FI connection management system 114 can determine if the WI-FI network 110 is congested based, at least in part, upon the utilization load. For example, the WI-FI connection management system 114 can maintain threshold parameters for when the WI-FI network 110 should be considered to be congested and when the WI-FI network 110 should be considered to be not congested. The WI-FI connection management system 114 generates the trigger 114 that includes instructions useable by the mobile device 102 to avoid turning on the WI-FI radio 108 even though the mobile device 102 is within the coverage of the WI-FI network 110.
Similarly, when the mobile device 102 leaves a coverage area provided by the WI-FI network 110, the WI-FI connection management system 114 can generate a trigger 116 that includes instructions useable by the mobile device 102 to deactivate the WI-FI radio 108, and send the trigger 116 to the mobile device 102 so as to instruct the mobile device 102 to deactivate the WI-FI radio 108. These instructions may additionally include instructions useable by the mobile device 102 to reactivate the cellular radio 104 or return the cellular radio 104 to an activated or “ON” state from a low-power or other state. Alternatively, when the mobile device 102 leaves a coverage area provided by the WI-FI network 110, the mobile device 102 can automatically deactivate the WI-FI radio 108 in response to a signal received from the WI-FI network 110 that is of a signal strength that at least meets a minimum signal strength threshold, or if no signal is received by the WI-FI radio 108.
The WI-FI connection management system 114 can generate the trigger 116 in response to knowledge of the location of the mobile device 102 being a location served by the WI-FI network 110. The WI-FI connection management system 114 can receive location information, such as latitude/longitude coordinate, cell identity (“CID”), location area identity (“LAI”), physical cell identity (“PCI”), triangulation data, or the like, from a location system 118. In some embodiments, the location system 118 is a mobile location center (“MLC”) operating in a serving or gateway capacity. Moreover, the location system 118 may include multiple MLCs, location registers, and/or other network elements to ascertain the location of the mobile device 102. As such, although the location system 118 is illustrated as being external to the mobile telecommunications network 106, the location system 118 may be part of the mobile telecommunications network 106. The WI-FI connection management system 114 may also be part of the mobile telecommunications network 106 or may be external to the mobile telecommunications network 106 as shown.
As an alternative to location information received from the location system 118, the WI-FI connection management system 114 can request and receive location information from the mobile device 102. In such implementations, the mobile device 102 can utilize a Global Positioning System (“GPS”), the cellular radio 104, and/or the WI-FI radio 108 to ascertain the location of the mobile device 102 utilizing GPS, cellular triangulation, and/or WI-FI triangulation techniques, and provide the location to the WI-FI connection management system 114 in response to the request received therefrom. In other embodiments, the mobile device 102 can provide the location to the WI-FI connection management system 114 periodically, or when the cellular radio 104 and/or the WI-FI radio 108 detects one or more signals originating from the WI-FI network 110.
The illustrated WI-FI connection management system 114 is also in communication with a user profile server 120, which, in turn, is in communication with a user profile database 122. The user profile server 120 can be configured to provide user profiles, including a user profile of a user of the mobile device 102, to the WI-FI connection management system 114 for use in generating the trigger 116 to selectively activate or deactivate the cellular radio 104 and/or the WI-FI radio 108. As used herein, the term “user profile” refers to a collection of data associated with a user that accesses the mobile telecommunications network 106 via a device such as the mobile device 102. A user in this context refers to an individual or other entity. In some embodiments, a user profile includes information regarding a service agreement between a user and a mobile telecommunications carrier that provides a service, at least in part, via the mobile telecommunications network 106 and/or the WI-FI network 110. In some embodiments, a user profile includes WI-FI network access information such as a service set identifier (“SSID”) and, if applicable, authentication credentials for one or more WI-FI networks, such as the WI-FI network 110. The authentication credentials can include, for example, user name, password, encryption key, combination thereof, and/or the like. It is contemplated that a user profile can be updated as the mobile device 102 connects to new WI-FI networks 110. As such, the WI-FI connection management system 114 can have knowledge of one or more WI-FI networks that the mobile device 102 has been connected to.
The illustrated WI-FI connection management system 114 is also in communication with a WI-FI authentication server 124. In some embodiments, the WI-FI authentication server 124 is configured to provide authentication credentials to users that have subscribed to or otherwise are authorized to access services provided by a mobile telecommunications carrier that owns and/or operates the mobile telecommunications network 106 and the WI-FI network 110. In some embodiments, the WI-FI authentication server 124 can provide authentication credentials to the WI-FI connection management system 114 for inclusion in the trigger 116. In this manner, the mobile device 102 can receive the trigger 116 that includes instructions to activate the WI-FI radio 108 and connect to the WI-FI network 110 utilizing the authentication credentials provided by the WI-FI authentication server 124. In some other embodiments, the WI-FI connection management system 114 can instruct the WI-FI authentication server 124 to negotiate a secure connection to the WI-FI network 110 when the mobile device 102 attempts to connect to the WI-FI network 110 after activating the WI-FI radio 108 in response to the trigger 116.
As explained above, the WI-FI network 110 may be owned and/or operated by the same mobile telecommunications carrier that owns and/or operates the mobile telecommunications network 106. In some embodiments, the mobile device 102 is configured to activate or deactivate the WI-FI radio 108 and/or the cellular radio 104 in response to detecting the WI-FI network 110 based upon a connection policy 126 stored on the mobile device 102. For example, the connection policy 126 may specify the SSID and, if required, the authentication credentials for accessing the WI-FI network 110. When the mobile device 102 detects the WI-FI network 110, the mobile device 102 can activate the WI-FI radio 108 based upon the connection policy 126.
The illustrated mobile device 102 also includes a connection manager 128. The connection manager 128 can be configured to manage all or a portion of the network connections available to the mobile device 102 at a given time, including, for example, connections that can be established via the cellular radio 104 or the WI-FI radio 108. In some embodiments, the network connection manager 128 is included as part of an operating system (not shown) of the mobile device 102 and/or another application stored on the mobile device 102.
It should be understood that some implementations of the operating environment 100 include multiple mobile devices 102, multiple mobile telecommunications networks 106, multiple WI-FI networks 110, multiple data networks 112, multiple WI-FI connection management systems 114, multiple location systems 118, multiple user profile servers 120, multiple profile databases 122, and/or multiple WI-FI authentication servers 124. It also should be understood that some implementations of the mobile device 102 include multiple cellular radios 104, multiple WI-FI radios 108, multiple connection policies 126, and/or multiple connection managers 128. Thus, the illustrated embodiment should be understood as being illustrative, and should not be construed as being limiting in any way.
Turning now to FIG. 2, a flow diagram illustrating aspects of a method 200 for triggering activation of a WI-FI radio of a mobile device will be described, according to an illustrative embodiment. It should be understood that the operations of the illustrative methods disclosed herein are not necessarily presented in any particular order and that performance of some or all of the operations in an alternative order(s) is possible and is contemplated. The operations have been presented in the demonstrated order for ease of description and illustration. Operations may be combined, separated, added, omitted, modified, and/or performed simultaneously or in another order without departing from the scope of the subject disclosure.
It also should be understood that the illustrated methods can be ended at any time and need not be performed in their entirety. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-executable instructions included on a computer-readable storage media, as defined below. The term “computer-executable instructions,” and variants thereof, as used in the description and claims, is used expansively herein to include routines, application programs, software, application modules, program modules, components, data structures, algorithms, and the like. Computer-executable instructions can be implemented on various system configurations, including single-processor or multiprocessor systems, distributed computing systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like. As used herein, “cause a processor to perform operations” includes causing a processor of a computing system or computing device, such as the mobile device 102, the WI-FI connection management system 114, the location system 118, the user profile server 120, or the WI-FI authentication server 124, to perform one or more operations of the operations and/or causing the processor to direct other components of the computing system or computing device to perform one or more of the operations.
Thus, it should be appreciated that the logical operations described herein may be implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
The method 200 begins and proceeds to operation 202, wherein the WI-FI connection management system 114 detects that the mobile device 102 is within a coverage area provided by the WI-FI network 110. The WI-FI connection management system 114 can receive location information from the location system 118 and/or directly from the mobile device 102 and can utilize the location information to determine if the location of the mobile device 102 is within a coverage area provided by the WI-FI network 110. From operation 202, the method 200 proceeds to operation 204, wherein the WI-FI connection management system 114 generates the trigger 116 to instruct the mobile device 102 to activate (e.g., turn ON) the WI-FI radio 108 and connect to the WI-FI network 110.
