Method and apparatus for handling user equipment capability information

摘要

A method and apparatus for a wireless communication system, sends an initial connection request with the device capabilities of an indicated mobile station. The device capabilities comprise both semi-static capabilities and dynamic capabilities. The semi-static capabilities are stored in the core network. Data is transmitted via a wireless node before the mobile station transitions to an idle state. When transitioning back to an active state from the idle state when the semi-static capabilities have not changed, a connection request is sent with the dynamic capabilities of the user equipment without also transmitting the semi-static mobile station capabilities to the wireless node.

主权项

1. A method operable in a wireless communication network, the method comprising:
sending an initial connection request, the initial connection request including device capabilities of an indicated user equipment, the device capabilities comprising a first set of radio access network capabilities and a second set of radio access network capabilities, the first set of radio access network capabilities including a packet access category for the indicated user equipment; storing the second set of capabilities included in the initial connection request; transmitting data via a wireless node; transitioning to an idle state; when transitioning back to an active state from the idle state when the second set of radio access network capabilities have not changed, sending a connection request with the first set of radio access network capabilities of the user equipment without also transmitting any of the second set of radio access network capabilities to the wireless node; and when transitioning back to an active state from the idle state when the second set of radio access network capabilities have changed, sending a connection request including the first set of radio access network capabilities of the user equipment and the changed radio access network capabilities included in the second set of radio access network capabilities, wherein the connection request including the first set of radio access network capabilities of the user equipment and the changed radio access network capabilities included in the second set of radio access network capabilities causes transmission of a storage request including at least the second set of radio access network capabilities to a core network, the storage request identifying elements of the second set of radio access network capabilities for storage until the user equipment de-registers from the network.
