摘要: Methods and apparatus are provided for a voice over LTE system to shorten the call set up time. In one novel aspect, mobile origination (MO) UE starts UE-initiated dedicated resource allocation before receiving any responses from remote UE. another embodiment, termination (MT) upon INVITE adjusts timeout value based on PLMN information in its database. The can be zero if early reservation is allowed. Upon timer expires, allocation. MO retrieves codec of peer profile database uses matching message. MT includes SDP answer 180 RINGING
