## Background
CROSS REFERENCE TO RELATED APPLICATION(S)
This application is a Divisional Application of pending U.S. application Ser. No. 12/200,583, filed Aug. 28, 2008, the entire content of which is incorporated herein by reference.


BACKGROUND
1. Field
The present application relates generally to wireless communications, and more specifically to techniques for automated configuration of access point base stations for restricted access.
2. Background
Wireless communication systems are widely deployed to provide various types of communication (e.g., voice, data, multimedia services, etc.) to multiple users. As the demand for high-rate and multimedia data services rapidly grows, there lies a challenge to implement efficient and robust communication systems with enhanced performance.
In recent years, users have started to replace fixed line communications with mobile communications and have increasingly demanded great voice quality, reliable service, and low prices. In addition to mobile phone networks currently in place, a new class of small base stations has emerged, which may be installed in a user's home and provide indoor wireless coverage to mobile units using existing broadband Internet connections. Such personal miniature base stations are generally known as an access point (AP) base station, also referred to as Home Node B (HNB) unit, femto cell, femto base station (fBS), base station, or base station transceiver system (BTS). Typically, such miniature base stations are connected to the Internet and the mobile operator's network via a digital subscriber line (DSL) router or cable modem.
AP base stations or femto cells allow for cellular access where normal base station support is weak or unavailable (e.g., indoors, remote locations, and the like). AP base stations may be described as small base stations that connect to wireless service providers via a broadband backhaul link, such as digital subscriber line (DSL), cable internet access, T1/T3, etc., and offer typical base station functionality, such as base transceiver station (BTS) technology, radio network controller, and gateway support node services. This allows an access terminal (AT), also referred to as a cellular/mobile device or handset, or user equipment (UE), to connect to the AP base stations and utilize the wireless service. It is noted that ATs can include, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, navigational devices, PDAs, and/or any other suitable device for communicating over a wireless communication system.
There currently exist AP base stations that by default operate in open access mode, such that they are open to all customers of the network operator or wireless service provider. Such AP base stations may be configured for restricted access, such that only selected ones of the operator customers have access to the network via the femto cell. However, existing approaches for restricted access configuration of AP base stations are prohibitively difficult and time consuming One existing approach is for the base station user/owner to call a customer care center of the network operator to create a list of approved phone numbers. Another approach commonly used in consumer networking equipment, such as Ethernet routers and wireless access points, is to serve Hyper Text Transfer Protocol (HTTP) web pages for the user to enter configuration information via a computer. Such approaches may be burdensome for consumers and may use up significant customer service resources. Accordingly, there is a need for an automated technique for restricted access configuration of AP base stations.
SUMMARY
The following presents a simplified summary of one or more embodiments in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments, and is intended to neither identify key or critical elements of all embodiments nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.
In accordance with one or more embodiments and corresponding disclosure thereof, various aspects are described in connection with controlling or restricting access to access point (AP) base stations. In particular, described herein are method and systems for restricted access configuration of AP base stations. For example, the configuration method may involve receiving a contact list from an access terminal (AT) or mobile device associated with the AP base station. The contact list may include information regarding a mobile device user's saved contacts.
From the received information regarding the contacts, saved contacts associated with the operator may optionally be identified. The method may involve retrieving identifiers for the respective identified contacts, and may yet further involve generating an allowed user list based at least in part on the at retrieved identifiers. The allowed user list may be utilized to restrict, control, or otherwise manage access to the AP base station.
In related aspects, the step of utilizing the allowed user list may involve, in response to a visitor AT or device entering a coverage area of an AP base station, determining whether a visitor identifier of the visitor AT matches at least one entry of the allowed user list. This step may further comprise, in response to the visitor identifier matching the at least one entry of the allowed user list, allowing the visitor AT to access the AP base station. In response to the visitor identifier not matching any entry of the allowed user list, the visitor AT may be denied to access the AP base station.
In further related aspects, the configuration method may involve receiving a calling history for the AT, and may further involve generating the allowed user list based at least in part on information in the calling history. This approach may be in lieu of or in addition to receiving and using the contact list from the AT.
According to further related aspects, there is provided a wireless communication apparatus for restricted access configuration of an AP base station, comprising a receiver, a memory, and at least one processor in operative communication with the receiver and the memory. The receiver may be adapted to receive a contact list, calling history, or the like from an AT associated with the AP base station.
The memory may include executable code for the at least one processor to configure restricted access to the AP base station based at least in part on the information of the contact list. The at least one processor may generate an allowed user list based at least in part on retrieved identifiers, and may utilize the allowed user list to control AP access.
To the accomplishment of the foregoing and related ends, the one or more embodiments comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative aspects of the one or more embodiments. These aspects are indicative, however, of but a few of the various ways in which the principles of various embodiments may be employed and the described embodiments are intended to include all such aspects and their equivalents.

DETAILED DESCRIPTION
Various embodiments are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiment(s) can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.
As previously mentioned, existing approaches for restricting access to access point (AP) base stations may be prohibitively difficult and time consuming for customers or require substantial operator customer service resources. The techniques described herein address the need for an automated technique that uses information stored on an AP base stations owner's access terminal (AT) (e.g., contacts lists, calling histories, etc.) to configure the AP base station for restricted access.
AP base stations can be deployed to individual consumers and placed in homes, apartment buildings, office buildings, and the like. An AP base station can communicate wirelessly with an AT in range of the AP base station utilizing a licensed cellular transmission band. Further, AP base stations may be connected to a core cellular network by way of an Internet Protocol (IP) connection, such as a Digital Subscriber Line (DSL, e.g., including Asymmetric DSL (ADSL), High data rate DSL (HDSL), Very high speed DSL (VDSL), etc.), a TV cable carrying Internet Protocol (IP) traffic, a Broadband over Power Line (BPL) connection, or like connection. The connection between the IP line and the cellular network can be a direct connection, or by way of the Internet. An AP base station, therefore, can provide cellular support to an AT or cellular handset and route cellular traffic (e.g., voice, data, video, audio, Internet, etc.) to a macro cellular network through the IP connection. This mechanism can save consumers air time costs and reduce a network provider's cellular network traffic load. Also, cellular coverage inside a home, office building, apartment, etc. can be greatly improved via implementation of AP base stations.
Although an AP base station is capable of forming a cellular link (e.g., a wireless link utilizing one or more licensed radio network frequencies) with multiple ATs, a consumer typically desires only his or her own traffic to be carried by a private IP connection connected to the AP base station. For instance, consumers may wish to preserve IP bandwidth for their own use, rather than for the use of other AT users. As a result, a AP base station is generally associated only with a single AT or group of ATs, and traffic related to such AT(s) is routed over the consumer's IP connection, whereas traffic related to other ATs is blocked. Consequently, although the AP base station can communicate with multiple ATs regardless of subscriber, the AP base station is typically programmed to ignore devices that are not associated with a particular consumer, service plan, and/or the like.
FIG. 1 illustrates an exemplary wireless communication system 100 adapted to support a number of users, in which various disclosed embodiments and aspects may be implemented. As shown in FIG. 1, by way of example, system 100 provides communication for multiple cells 102, such as, for example, macro cells 102a-102g, with each cell being serviced by a corresponding AP base station 104 (such as AP base stations 104a-104g). Each cell may be further divided into one or more antenna groups, also referred to as sectors. Various ATs 106, including ATs 106a-106k may be dispersed throughout the system 100. Each AT 106 may communicate with one or more APs 104 on a forward link and/or a reverse link at a given moment, depending upon whether the AT is active and whether it is in soft handoff, for example. The wireless communication system 100 may provide service over a large geographic region, for example, macro cells 102a-102g may cover a few blocks in a neighborhood.
Referring now to FIG. 2, a wireless communication system 200 is illustrated in accordance with various embodiments presented herein. System 200 comprises a base station 202 that can include multiple antenna groups. For example, one antenna group can include antennas 204 and 206, another group can comprise antennas 208 and 210, and an additional group can include antennas 212 and 214. Two antennas are illustrated for each antenna group; however, more or fewer antennas can be utilized for each group. Base station 202 can additionally include a transmitter chain and a receiver chain, each of which can in turn comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art. Base station 202 can communicate with one or more ATs, such as, for example, AT 216 and AT 222.
As depicted in FIG. 2, AT 216 is in communication with antennas 212 and 214, where antennas 212 and 214 transmit information to AT 216 over a forward link 218 and receive information from AT 216 over a reverse link 220. Moreover, AT 222 is in communication with antennas 204 and 206, where antennas 204 and 206 transmit information to AT 222 over a forward link 224 and receive information from AT 222 over a reverse link 226. In a Frequency Division Duplex (FDD) system, forward link 218 can utilize a different frequency band than that used by reverse link 220, and forward link 224 can employ a different frequency band than that employed by reverse link 226, for example. Further, in a Time Division Duplex (TDD) system, forward link 218 and reverse link 220 can utilize a common frequency band and forward link 224 and reverse link 226 can utilize a common frequency band.
Each group of antennas and/or the area in which they are designated to communicate can be referred to as a sector of base station 202. For example, antenna groups can be designed to communicate to ATs in a sector of the areas covered by base station 202. In communication over forward links 218 and 224, the transmitting antennas of base station 202 can utilize beamforming to improve signal-to-noise ratio of forward links 218 and 224 for ATs 216 and 222. Also, while base station 202 utilizes beamforming to transmit to ATs 216 and 222 scattered randomly through an associated coverage, ATs in neighboring cells can be subject to less interference as compared to a base station transmitting through a single antenna to all its ATs. Moreover, ATs 216 and 222 can communicate directly with one another using a peer-to-peer or ad hoc technology in one example.
Similar functionality of base station 202 can be implemented in AP base stations 228 and 230, which can be deployed in smaller scale locations, such as a residence or office building for example. As mentioned previously, AP base stations are also referred to as femto cells or Home Node B (HNB) units, and can have a broadband backhaul link to a wireless service provider, such as over DSL, cable, T1/T3, etc., and can provide wireless communication service to one or more ATs. As shown, AP base station 228 can communicate with one or more AT(s) 232 over a forward link 234 and receive communication from the AT(s) 232 over a reverse link 236 similarly to the base station 202.
According to an example, AP base station 230 can be deployed to provide wireless service access. AP base station 230 can connect to a wireless service access provider via broadband backhaul link, one or more disparate femto cells or macro cells over-the-air, etc. Upon being deployed, AP base station 230 can optionally self-configure to avoid interference with surrounding femto cells (e.g., AP base station 228) and macro cells (e.g., base station 202 or a sector/cell thereof). In this regard, AP base station 230 can receive signals from the base station 202 and disparate AP base station 228 much like ATs 216, 222, and 232. The signals can be overhead system messages that can be utilized by the AP base station 230 to determine configuration parameters utilized by the disparate AP base station 228 and/or base station 202.
The configuration parameters can be determined by AP base station 230 for similar environment configuration. In addition, the parameters can be determined and utilized to ensure AP base station 230 selects different parameters to mitigate interference. These parameters can include, for example, a channel identifier (e.g., a Code Division Multiple Access (CDMA) channel ID), a pseudo-noise (PN) offset, and/or the like, for AP base station 228, base station 202, and/or substantially any other surrounding transmitters. AP base station 230 can accordingly self-configure its channel identifier, PN offset, etc. so as not to interfere with the surrounding femto cells and macro cells. Additionally, AP base station 230 can utilize this information to build a neighbor list of surrounding femto cells and macro cells to facilitate hard and soft handoffs for devices communicating with AP base station 230. It is noted that AP base station 230 may be adapted to receive RF signals, for example, from AP base station 228 and/or base station 202 to determine timing, location, and/or the like.
FIG. 3 provides a block diagram of an exemplary communication system 300 with automated restricted access configuration of an AP base station 310 based at least in part on information from or associated with an AT 302 adapted to communicate on a network of a given network operator. The system 300 may include AP base station 310 in operative communication with a Femto Access Manager (FAM) 314 or the like via a broadband backhaul link 312, such as, for example, DSL, cable internet access, T1/T3, or the like.
It is noted that, while only one AP base station 310 is shown in FIG. 3, the system 300 may include multiple AP base stations, each being installed in a corresponding small scale network environment, such as, for example, in one or more user residences, and being adapted to serve associated, as well as alien, AT(s). It is further noted that, although certain embodiments described herein use 3GPP terminology, the embodiments may be applied to 3rd Generation Partnership Project (3GPP) (Re199, Re15, Re16, Re17) technology, as well as 3GPP2 (1xRTT, 1xEV-DO Rel0, RevA, RevB) technology, and other known and related technologies.
The system 300 may also include a node B or base station 320 in operative communication with a radio network controller (RNC) 322 or the like. The RNC may be in operative communication with a message switching center (MSC) 324 or similar service delivery node responsible for handling voice calls, short message service (SMS), as well as other services (e.g., conference calls, FAX and circuit switched data). The MSC 324 or the like may set up and release the end-to-end connections, handle mobility and hand-over requirements during the call, take care of charging and real time pre-paid account monitoring, etc.
The MSC 324 may include, or otherwise be in communication with, a visitor location register (VLR) 326 or similar temporary database of network subscribers who have entered or roamed into a particular area. The VLR 326 may be in operative communication with a registry 328, which may generally comprise a database that contains details of mobile phone subscribers authorized to use the operator's network. For example, the registry 328 may comprise an HLR in the illustrative context of a Global System for Mobile Communications (GSM) core network.
The MSC 324 may be in operative communication with a public switched telephone network (PSTN) 330 or the like. The system 300 may further include additional MSCs and registries in operative communication with the MSC 324, such as, for example, MSC 324′, VLR 326′, and registry 328′.
The FAM 314 may comprise a computing/network device or server, and may be in operative communication with a database 316. The database 316 may store information including or relating to one or more of AP base station identities, owner identities, owner passwords, allowed identities, or the like.
In related aspects, the customer or user of the AT 302 may add phone numbers to a contact list/phonebook on his/her AT 302. The contact list may be stored as a data file on the AT 302 and/or remotely, such as, for example, at a FAM 314 or registry 328 of the network. It is noted that the AT 302 may comprise one or more contact lists. In one embodiment, the AT 302 may store a single contact list for the mobile device user. In another embodiment, the AT 302 may store multiple contact lists, such as, for example, a general contact list and a restricted access contact list for those contacts that the AT user wishes to provide AP base station access. The restricted access contact list may be a subset of the general contact list. It is noted, however, that the allowed user list generated by the FAM 314 may comprise a subset of the user's restricted access contact list since it is possible that some of the contacts in the user's restricted access contact list may not be customers of the network/service that the user's AP base station 310 is associated with.
For example, the contact list stored on AT 302 may be sent to or retrieved by a network entity, such as, for example, AP base station 310 and optionally FAM 314. This may be accomplished via an application level software on the AT, such as, for example, a BREW-based application. The transmission of the contact list to AP base station 310 may be initiated by the user of AT 302 (e.g., with prompts from the BREW application), and/or by service center personnel associated with the network.
The user of AT 302 may enter a password associated with his/her AP base station 310 to validate his/her ownership of the AP base station 310. For example, the password may comprise a base station/unit/equipment specific password supplied with AP base station 310. In the alternative, or in addition, service personnel may check or cross-reference the identity of AT 302 with the AP base station identity in database 316 to verify there is a match between the mobile device identity and the AP base station identity.
FAM 314 or other network entity may look up the AP base station identity for a given transaction based at least in part on an AT identity (ID), identifier, and/or other related data entered by the AT user. FAM 314 or other network entity may validate the given transaction by using the AT ID and/or the password. For example, FAM 314 may validate the transaction when the AT's ID matches a stored owner's AT ID or the like.
The collected contact list may optionally be processed by a network entity with access to the network operator's phone number database. Phone numbers belonging to other operators may be eliminated. Valid phone numbers (i.e., those phone numbers belonging to those contacts in the contact list who are customers of the network that AP base station 310 is associated with) may be looked up by the network entity to produce equipment or device IDs, International Mobile Subscriber Identity (IMSI), or other identifiers used to control network/system access.
For example, FAM 314 may process the received contact list and may communicate with the one or more registries 328 to convert the stored phone numbers of the contact list into subscriber identities. It is noted that all, a subset, or sometimes none of the stored phone numbers may correspond to subscribers of the network which AP base station 310 is associated with. With respect to those phone numbers corresponding to the network subscribers, the subscriber identities and/or related information may be gathered and used to generate an allowed user list. The allowed user list may be saved in FAM 314, and FAM 314 may optionally perform restricted access control for AP base station 310 during call setup. In the alternative, or in addition, the allowed user list may be sent to AP base station 310 securely, such that AP base station 310 may perform restricted access control itself
The subscriber identities in the allowed user list may be transmitted and stored in a secure manner, such that it is difficult to read out of or steal such information from AP base station 310. For example, the subscriber identifies in the allowed user list may be of a temporary nature, such as a Temporary Mobile Subscriber Identity (TMSI) or the like. In the alternative, or in addition, one or more secure private networks (SPNs) may be established within backhaul 312 to provided secured communication between FAM 314 and AP base station 310. Each SPN may provide an IP secure tunnel across one or more segments of a public network, which may include one or more public portions of the Internet (e.g., 802.3, DSL, cable, Ethernet, etc.).
The SPNs may be established according to any known technique, such as, for example, via the creation of virtual private networks (VPNs), in which some of the links between nodes are carried by open connections or virtual circuits in a larger network, such as, for example, public portions of the Internet. Link-layer protocols of the virtual network may be tunneled through the larger network. It is noted that the public network may comprise any communication network, wired or wireless, utilizing any known standards, such as, for example, a wide area network (WAN), a campus area networks (CAN), a metropolitan area networks (MAN), a wireless application protocol (WAP), etc. It is further noted that the public network may include a wireless local area network (WLAN), such as, for example, 802.11a, 802.11b, 802.11g, 802.11n, etc. The WAN macro cell may be based on Ultra Mobile Broadband (UMB), Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAx), etc. The system 300 may comprise WAN macro cells and femto cells deployed within the same general geographical area that reuse the same carrier as the WAN system. The WAN system may use legacy technology, such as, for example, UMB, while the femto system may use a new technology, such as, for example, an evolved version of UMB that supports AP base station operation efficiently.
In further related aspects, AT 302 may comprise a data file that may be sent to AP base station 310, FAM 314 or another network entity for the generation of the allowed user list. For example, the data file may comprise a phone or contact list, as explained above. In another example, the data file may comprise a phone's calling history, as generally kept for quick reference by the phone user and/or for billing records within the network. Accordingly, information stored in the data file (e.g., the contact list, the calling history, and variations/combinations thereof) may be used to generate the allowed user list. Again, it is noted that only a subset of the information in the data file may be used to create or be a part of the allowed user list, since some of the contacts or phone numbers in the data file may not correspond to customers who subscribe to or are associated with the AP base station's network. Further, it is noted that the data file may be located on AT 302. In the alternative, or in addition, the data file may be stored remotely, relative to AT 302, such as, for example, at FAM 314, registry 328, or other network entity.
With reference to FIG. 4, there is provided an exemplary system 400 that includes an AP base station 402 with a receiver component/module 410 adapted to receive signal(s) from AT(s) 404 or from other AP base stations (not depicted) through a plurality of receive antennas 406. AP base station 402 may also include a transmitter component/module 426 adapted to transmit to AT 404 or the like through one or more transmit antennas 408. Receiver component 410 may receive information from receive antennas 406 and may further comprise a signal recipient (not shown) that receives uplink data transmitted by the AT(s) 404. It should be appreciated that receiver component 410 and transmission component 426 may both include WLAN, BPL, Ethernet, Universal Mobile Telecommunication System (UMTS) TDD, or WLAN over UMTS TDD spectra communication capabilities to interact with ATs or with other AP base stations.
Receiver component 410 may be operatively associated with a demodulator 412 adapted to demodulate received information. Demodulated symbols may be analyzed by a network processor 422 to generate additional signals (e.g., in the form of transmission and/or routing instructions) modulated by modulator 424 and transmitted by transmitter component 426. Further, processor 422 may be coupled to a memory module/component 420. Memory module 420 may store information pertinent to effectuating wired and/or wireless communication, application modules for maintaining a femto network and routing information between AP base stations and/or with connected ATs, and/or any other suitable information related to performing the various actions and functions set forth herein.
Processor 422 may route at least a portion of traffic associated with a communication link between AP base station 402 and AT 404 to a neighboring AT base station (not depicted) for transfer to a cellular network (e.g., by way of a direct connection to the cellular network, or by way of the Internet). Furthermore, processor 422 may be adapted to direct traffic affiliated with AP base station 402 (e.g., generated by a predetermined AT or group of ATs, for instance) directly to the cellular network by way of an IP upload link 430 (e.g., DSL connection, such as ADSL, VDSL, HDSL etc., cable IP connection, BPL connection). In addition, data may be received from the cellular network via an IP download link 428 (e.g., DSL, cable, BPL) and directed to AT 404 affiliated with the AP base station 402. It is noted that AP base station 402 may comprise one or more processors 422.
Receiver component 410 and transmission component 426 may receive and transmit, respectively, various information to/from a cellular network (e.g., via IP upload 430 and/or IP download 428) or to/from other AP base stations of the femto network by way of an IP router 427 that communicates over unlicensed frequencies or wired connections (e.g., WLAN router, LAN router, or the like). It is noted that the receiver and transmitter components/modules 410, 426 may be part of or replaced with a transceiver module (not depicted) in other embodiments. The depicted receiver 410 and transmitter 426, or alternatively a transceiver, may be adapted to support communication links with a plurality of AP base stations.
In related aspects, memory 420 may contain application modules or applications that generate or comprise code/instructions for configuring AP base station 402 for restricted access. For example, memory 420 may include executable code for processor 422 to retrieve or receive a data file, such as, for example, a contact list or calling history, from AT 404. The contact list and/or calling history may include information (e.g., phone numbers) of the AT user's saved contacts. Memory 420 may further include executable code for processor 422 to configure restricted access to AP base station 420 based at least in part on the contact list and/or calling history from AT 404.
Memory 420 may further include executable code for processor 422 to verify ownership of AP base station 402, such as by receiving a password associated with the AP base station 402. Memory 420 may comprise a password (specific for AP base station 402) supplied with base station 402, which the user of AT 404 should provide to a network entity (e.g., base station 402, the FAM, etc.) to validate his/her ownership of the base station 402. Processor 422 may optionally be adapted to instruct transmitter 426 to send the password to another network entity (e.g., the FAM) upon establishing a secured communication tunnel with the network entity. In the alternative, or in addition, the FAM or the like may comprise or otherwise have access to a database of passwords that are specific to one or more AP base stations.
AP base station 402 may be associated with a network operator, and memory 420 may optionally further include executable code for processor 422 to identify those saved contacts in the contact list (or telephone numbers in the calling history) that are associated with the network operator. Memory 420 may further include executable code for processor 422 to retrieve an identifier for such contacts from the contact list, to generate an allowed user list based at least in part on the retrieved identifier, and to utilize the allowed user list to configure the restricted access to the cellular network via AP base station 402.
In response to a visitor AT entering a coverage area of AP base station 402, processor 422 may be adapted to determine whether a visitor identifier of the visitor AT matches at least one entry of the allowed user list. When the visitor identifier matches at least one entry of the allowed user list, processor 422 may be adapted to allow the visitor AT to access a network via AP base station 402.
