User equipment capability handling in long-term evolution systems
Systems, methodologies, and devices are described that facilitate management of user equipment (UE) capability information in a network to facilitate improved connection and communications associated with a mobile device. A core network can include a capability management component that can control UE capability information received during an initial connection of the mobile device to the network, where the UE capability information comprises UE dynamic capability and UE semi-static capability. The UE dynamic capability and semi-static capability can be identified from the received capability information and stored and managed respectively. When the initial connection is released, the dynamic capability information is deleted while the semi-static capability information can be retained in the core network. During a subsequent connection of the mobile device to the network, the stored semi-static capability can be retrieved and utilized to facilitate efficiently selecting a desired dynamic capability for the subsequent connection and communication.

controlling storage of capability information associated with a core network;
maintaining storage of the semi-static capability information at the core network after a first connection associated with the mobile device is released;
receiving the capability information associated with the mobile device at the core network; and
storing the one or more identified items of information at the core network, further comprising:
deleting from at least one device of the core network the dynamic capability information in response to the first connection associated with the mobile device being released.
2. The method of claim 1 , further comprising:
retrieving at the core network the semi-static capability information stored at the core network during a second connection associated with the mobile device, the second connection being subsequent to the first connection; and
transmitting the retrieved semi-static capability information to a base station to facilitate selection of a dynamic capability to be utilized by the mobile device during the second connection.
3. The method of claim 1 , further comprising:
releasing the first connection associated with the mobile device, the releasing of the first connection comprising transitioning of the mobile device to an idle state.
4. A method of communication associated with a mobile device, comprising:
identifying one or more items of information from capability information of the mobile device based at least in part on one or more predefined identification criteria, the one or more items of information comprising at least one of dynamic capability information and semi-static capability information associated with the mobile device;
controlling storage of capability information associated with a core network;
maintaining storage of the semi-static capability information at the core network after a first connection associated with the mobile device is released, further comprising:
deleting from at least one device of the core network the semi-static capability information when the mobile device is in an off state.
5. A wireless communications apparatus that facilitates communication associated with a mobile device, comprising:
means for respectively identifying dynamic capability and semi-static capability associated with the mobile device based at least in part on one or more predefined identification criteria:
means for controlling storage of capability information associated with the mobile device at a core network; and
means for maintaining storage of the semi-static capability information at the core network after a connection associated with the mobile device is released, wherein the means for controlling storage of capability information associated with the mobile device comprises:
means for deleting from at least one device of the core network the dynamic capability information in response to the mobile device transitioning to an idle mode.
6. A computer program product, comprising:
a non-transitory computer-readable medium comprising code for:
identifying one or more items of information from capability information of a mobile device based at least in part on one or more predefined identification criteria, the one or more items of information comprising at least one of dynamic capability information and semi-static capability information associated with the mobile device;
controlling storage of capability information associated with the mobile device at a core network; and
maintaining storage of the semi-static capability information at the core network after a connection associated with the mobile device is released, wherein the computer-readable medium further comprises code for:
deleting the dynamic capability information in response to the mobile device transitioning to an idle mode; and
retaining the semi-static capability information after the mobile device transitions to the idle mode.
7. The computer program product of claim 6 , wherein the computer-readable medium further comprises code for:
transmitting the semi-static capability information from the core network to a base station associated with the mobile device in response to the mobile device transitioning to an active state and requests to establish a connection with the base station, the step of transmitting being performed after the steps of deleting and retaining.
8. In a wireless communications system, an apparatus comprising:
a processor configured to:
identify one or more items of information from capability information of a mobile device based at least in part on one or more predefined identification criteria, the one or more items of information comprising at least one of dynamic capability information and semi-static capability information associated with the mobile device;
manage storage of capability information associated with the mobile device; and
maintaining storage of the semi-static capability information at the core network after a connection associated with the mobile device is released, wherein the processor is further configured to:
