Method to use existing NAS signaling connection for pending uplink signaling/data after TAU accept
First Claim
1. A method for operating a user equipment, the method comprising:
- transmitting, to a network node, a tracking area update (TAU) request message via a signaling connection;
receiving, from the network node, a TAU accept message via the signaling connection according to the TAU request message; and
transmitting, to the network node, a TAU complete message via the signaling connection according to the TAU accept message,wherein the TAU complete message comprises an information element (IE) for requesting to retain the signaling connection.

Abstract
A method and system to use existing Non-access stratum (NAS) signaling connection for pending uplink signaling/data after Tracking Area Update Procedure (TAU) complete is disclosed. The proposed method handles the EPS Session Management (ESM), Short Message Service (SMS) or voice call or data when a User Equipment (UE) is waiting for TAU accept. The method allows UE to inform the network with specific Information Element (IE) in TAU complete message, so that the network will take the next action. This will help to provide quick services to the user. Using the “CONN REQ TYPE” IE, in TAU complete, to handle all abnormal Cases for Circuit Switches (CS) services/data services in E-UTRAN (Evolved UTRAN) network.
