User equipment capability update in wireless communications
First Claim
1. A method for updating mobile device capabilities in wireless communication networks, comprising:
- determining a change in capability of a wireless device in an active mode;
transmitting an unsolicited radio resource control connection re-establishment message indicating the change in capability, wherein the unsolicited radio resource control message is an existing message utilized to re-establish a connection with the wireless communication network when a mobile device switches from idle mode to active mode;
receiving a radio resource control capability response message indicating acceptance or denial of the change in capability; and
initializing a timer to restrict retransmitting the unsolicited radio resource control message based at least in part on the radio resource control capability response message indicating denial.

Abstract
Systems and methodologies are described that facilitate unsolicited indication of mobile device capability change in wireless communication networks. Upon establishing communication with an access point, a mobile device can experience a change in capability, such as by attaching a device, changing a setting in a user interface, and/or the like. Rather than waiting for a reconfiguration command, when changing base stations or switching from idle to active mode, the mobile device can transmit an unsolicited message to the access point indicating the change. The access point can support the change in subsequent uplink communications or deny such support and can accordingly notify the mobile device via radio resource control (RRC) message.

8. A wireless communications apparatus, comprising:
-
at least one processor configured to; receive indication of capability change in the wireless communications apparatus in an active mode; generate a radio resource control connection re-establishment message indicating the capability change, wherein the radio resource control connection re-establishment message is an existing message utilized to re-establish a connection when a mobile device switches from idle mode to active mode; transmit the radio resource control connection re-establishment message without solicitation to an access point providing wireless network access to the wireless communications apparatus; and receive a radio resource control capability response message from the access point indicating acceptance or denial of the capability change, wherein the radio resource control capability response message indicates denial of the capability change and specifies a timer that restricts re-requesting the capability change; and a memory coupled to the at least one processor. - View Dependent Claims (9, 10, 11, 12)

13. A wireless communications apparatus, comprising:
-
means for detecting a capability change in the wireless communications apparatus in an active mode; means for creating an unsolicited radio resource control connection re-establishment message related to the capability change, wherein the unsolicited radio resource control connection re-establishment message is an existing message utilized to re-establish a connection when a mobile device switches from idle mode to active mode; and means for transmitting the unsolicited radio resource control connection re-establishment message to a disparate device to request support for the capability change; and means for receiving a radio resource control capability response message from the disparate device in response to the radio resource control message, wherein the radio resource control capability response message indicates the capability change is denied and further comprises a timer before which the radio resource control message can be re-transmitted. - View Dependent Claims (14, 15, 16)
