Short access for realizing a signaling radio bearer in geran
First Claim
1. A method of establishing a signaling radio bearer (SRB) for control signaling between a mobile terminal and a radio access network, the method comprising:
- transmitting an access request message from said mobile terminal to said radio access network, said access request message comprising a SRB resource request that identifies the type of SRB being requested;
receiving an uplink assignment message from said radio access network responsive to said SRB resource request, said uplink assignment message allocating specified SRB resources to said mobile terminal; and
transmitting control signaling messages from said mobile terminal to said radio access network using said specified SRB resources allocated to said mobile terminal in said uplink assignment message.

Abstract
An method of establishing a radio bearer (RB) resource in an RAN to support communication with a mobile terminal uses a radio bearer resource request message to expedite RB resource allocation. The mobile terminal transmits a packet channel access request message that uniquely identifies the access request type as a RB access request. The requested RB may be a signaling radio bearer (SRB), in which case the RB access request message may identify the specific type of SRB desired. More generally, the RB access request message identifies the access request type as a RB resource request, which is enough to alert the RAN that RB resources are required. The RAN then sends an uplink packet channel assignment and the mobile terminal specifies the RB resource details by transmitting RLC header information on the assigned uplink channel.
