    摘要： Methods and apparatus for providing inter-RAT mobility between 2G/3G and 4 networks are described. A UE camped or connected to a GERAN or UTRAN network may be configured to move, either directly or through network-controlled functions, to an LTE network to perform a data call. The UE may then return to a 2G/3G network.

    摘要： Creation of update of a security context between user equipment and MSC/VLR (Mobile Switching Centre/Visitor Location Register) for circuit switched domain services is provided. The creation or update is based on conversion of the security context used in an evolved Universal Terrestrial Radio Access Network (E-UTRAN) in the Mobility Management Entity (MME) to a security context for the circuit switched domain target system and transferring it to a MSC/VLR. When user equipment is moved from E-UTRAN to GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network (GERAN/UTRAN), a MME does not need to perform authentication and key agreement procedures to establish shared circuit switched security context for the user equipment.

    摘要： Devices and methods are provided for subscription data optimization in a wireless communication system. In one embodiment, the method may involve receiving an update location request from a mobile entity and forwarding the update location request to a subscriber data repository. The method may involve receiving a profile identifier from the subscriber data repository, the profile identifier corresponding to profile parameters for a subscription service for the mobile entity. The method may also involve accessing a lookup table to determine the profile parameters associated with the profile identifier, and determining whether to authorize the subscription service based at least in part on the profile parameters.

    摘要： Methods and apparatuses are provided that facilitate avoiding establishment of unnecessary radio bearers in circuit switched fallback (CSFB). A CSFB procedure related to a device can be detected from receiving an extended service request or a forward relocation request, or from determining that an evolved packet system (EPS) is insufficient to handle a circuit switched voice call, and/or the like. Based at least in part on detecting the CSFB, establishment of radio bearers for inactive EPS bearers can be avoided. Where the device is in idle mode before CSFB, avoiding establishment of radio bearers can include avoiding establishment of all data radio bearers for the device.

    摘要： A technique is disclosed to minimize service interruption at a wireless user equipment device during a handover by maintaining dual active connections during the handover. Upon initiating the handover, an initial/first connection with a first access node is maintained while establishing a second connection with a second access node. The user equipment device can receive data over the first connection and second connection during the handover. The first connection may be terminated (by the user equipment device or by timing out due to inactivity) after the handover is completed. Other aspects, embodiments, and features are also claimed and described.
