Abstract: Techniques are provided for conserving network resources in a network that initiates data services by communicating push data to a dormant terminal. Selected network resources associated with the dormant terminal are released, and maintained information for reaching the dormant terminal is updated when the point of network attachment of the dormant terminal changes.

Abstract: Method and apparatus for effecting handoff in a system supporting both wireless and packet data service communications. In one embodiment, the serving network provides information to the target network sufficient to establish the Point-to-Point Protocol (PPP) connections for handoff. In an alternate embodiment, the serving network and the target network do not share capabilities with respect to concurrent multiple service instances. When the serving network knows the status of the target network, the serving network takes responsibility for the handoff.

Abstract: A method and apparatus for providing policy control in a wireless communication system. A mobile station generates a resource request for a communication service, where the resource request includes an identifier uniquely identifying a type of communication service. A packet data serving node receives the resource request for the communication service and selects a policy control entity to process the resource request. The selection by the packet data serving node is based at least on the identifier. The selected policy control entity performs policy control on the resource request.

Abstract: A method and apparatus of providing packet data services that includes establishing an over-the-air communication connection between a mobile station and a wireless network infrastructure. The mobile station communicates a version and capability indication of a wireless packet data standard supported in the mobile station to the wireless network infrastructure. The wireless network infrastructure communicates a version and capability indication of the wireless packet data standard supported in the network infrastructure to the mobile station. Operation of the mobile station and wireless network infrastructure are adjusted in accordance with the indicated versions and capabilities.

Abstract: Systems and methods for determining the home network carrier associated with a mobile station and authorizing the provision of services to the mobile station using centralized storage of mobile station and home network information. In one embodiment, when a roaming mobile station attempts to access services, identifying information for the mobile station is used by a local server to query a centralized DNS server that stores a mapping of mobile station identifying information to corresponding home networks. The centralized DNS server returns an identification of the home network of the roaming mobile user, and the home network then determines whether to grant or deny the mobile station access to the local network. The mobile station identifying information may comprise an MSID such as an MIN, IRM or IMSI, which may serve as part of the address for the query to the centralized DNS server.

Abstract: Mobile unassisted dormant handoff in a wireless communication system supporting packet data communications. While in a dormant mode, a mobile node may change packet zones, wherein different packet zones are serviced by at least one different infrastructure element, without identifying the change to the system. The change in packet zone does not necessarily trigger establishment of a communication path for the mobile node until there is packet data ready for communication. In one embodiment, mobile assistance is adapted to the system, and is disabled at the mobile node by an indication in a system parameter message transmitted by the system and received by the mobile node.

Abstract: Methods and apparatus for compression of headers in broadcasting BCMCS services in a wireless communication system are described. Techniques used in BCMCS systems without feedback include sending static context information during BCMCS service initialization for use in a decompressor in a mobile station. Techniques used in BCMCS systems with feedback include receiving feedback from distributed mobile station decompressors and adjusting the broadcasting compressor in response to the feedback. Techniques that reduce the number of operating states in both the compressor and the decompressor are described. Techniques to classify flows so that a reduced number of contexts are used to compress/decompress session packet headers in a push-to-talk service are described.

Abstract: Method and apparatus for providing Cellular Authentication Voice Encryption (CAVE) messages in an Extensible Authentication Protocol (EAP) format. The CAVE messages are sent via an EAP transport mechanism. The Mobile Station (MS) is able to use a common authentication mechanism for other technologies.

Abstract: A communication system generates a Master Session Key (MSK) for accesses to a system entity that does not provide encryption to traffic. Both the home server and the user generate the same MSK. The MSK is used to generate encryption keys for traffic. In one embodiment the MSK is generated using a hashing function and information specific to the requester. The home server determines the need to generate the MSK based on information contained in an access request message. Once generated, the MSK is provided to the system entity to enable the entity to encrypt communications.

Abstract: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve wireless communications wherein a packet data session may be established between a wireless communications device and a packet data serving node to support a network connection to a packet-switched network. The wireless communications device may be configured to receive a notification of an incoming call from a circuit-switched network even when the network connection is active.

Abstract: A method and apparatus for a wireless communication system having a plurality of terminals is provided. At least one quality requirement defining a minimum quality of communication service threshold for receiving information by at least one terminal over a communication channel is determined. At least one quality parameter of the communication channel is also determined, where the quality parameter defines a degree of quality in which communication is received by the terminal over the communication channel. The quality parameter is compared to the quality requirement, and the terminal is prevented from tuning to the communication channel providing that the quality parameter is lower than the quality requirement. In another embodiment, the at least one quality requirement is associated with a service threshold indicator (STI) value, and the STI value is communicated to the terminal for comparison of the quality requirement to the quality parameter.

Abstract: A system, method and apparatus for providing location services whereby location determination and location disclosure are treated as separate and independent processes. Location determination may be performed (as necessary) via a first set of network entities to obtain location information for a mobile station. The location information may be cached for subsequent disclosure to any number of applications. Location disclosure may be performed (when requested) via a second set of network entities to provide the location information. Location determination may utilize a first security procedure for authentication and authorization and to obtain a first session key used for location determination. Location disclosure may utilize a second security procedure for authentication and authorization and to obtain a second session key used for location disclosure. For a roaming mobile station, location determination may be performed via a serving network and location disclosure may be performed via a home network.
