1. A method of random access in wireless communications, comprising:
- determining a user equipment (UE) capability identifier based on a UE capability and an access stratum (AS) release of the UE, wherein the UE capability identifier and the AS release uniquely identify the UE capability;
transmitting a radio resource control (RRC) connection request message;
receiving an RRC connection setup message;
transmitting a modified RRC connection setup complete message that does not include the UE capability; and
receiving a query from a network to report the UE capability after transmitting the modified RRC connection setup complete message, wherein the network sends the query in response to the RRC connection request message not including the UE capability identifier and upon receiving a common identifier (ID) message from a serving general packet radio service (GPRS) support node (SGSN), and wherein the common ID message does not include the UE capability.

9. A user equipment (UE), comprising:
-
means for determining a user equipment (UE) capability identifier based on a UE capability and an access stratum (AS) release of the UE, wherein the UE capability identifier and the AS release uniquely identify the UE capability; means for transmitting a radio resource control (RRC) connection request message; means for receiving an RRC connection setup message; means for transmitting a modified RRC connection setup complete message that does not include the capability; and means for receiving a query from a network to report the UE capability after transmitting the modified RRC connection setup complete message, wherein the network sends the query in response to the RRC connection request message not including the UE capability identifier and upon receiving a common identifier (ID) message from a serving general packet radio service (GPRS) support node (SGSN), and wherein the common ID message does not include the UE capability.

10. A non-transitory computer-readable medium, including:
-
code executable by a computer to determine a user equipment (UE) capability identifier based on a UE capability and an access stratum (AS) release of the UE, wherein the UE capability identifier and the AS release uniquely identify the UE capability; code executable by the computer to transmit a radio resource control (RRC) connection request message; code executable by the computer to receive an RRC connection setup message; code executable by the computer to transmit a modified RRC connection setup complete message that does not include the UE capability; and code executable by the computer to receive a query from a network to report the UE capability after transmitting the modified RRC connection setup complete message, wherein the network sends the query in response to the RRC connection request message not including the UE capability identifier and upon receiving a common identifier (ID) message from a serving general packet radio service (GPRS) support node (SGSN), and wherein the common ID message does not include the UE capability.

11. A user equipment (UE), comprising:
-
a radio resource control (RRC) connection set up component configured to; determine a user equipment (UE) capability identifier based on a UE capability and an access stratum (AS) release of the UE, wherein the UE capability identifier and the AS release uniquely identify the UE capability; transmit a radio resource control (RRC) connection request message; receive an RRC connection setup message; transmit a modified RRC connection setup complete message that does not include the UE capability; and receive a query from a network to report the UE capability after transmitting the modified RRC connection setup complete message, wherein the network sends the query in response to the RRC connection request message not including the UE capability identifier and upon receiving a common identifier (ID) message from a serving general packet radio service (GPRS) support node (SGSN), and wherein the common ID message does not include the UE capability. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
