Paging information transmission method for effective call setup
Disclosed is the method for transmitting paging information in wireless communication system, a core network transmits a paging message including call related information and/or terminal related information, at least one of a network or terminal performs a next operation based on the paging message, thereby effectively minimizing call setup time.
1. A method for transmitting paging information in a wireless communication system, the method comprising:
transmitting a paging message,
wherein the paging message includes call related information and terminal related information, and
wherein at least a network or terminal performs an operation based on the call related information and the terminal related information included in the paging message,
wherein the terminal related information is related to at least a function or capability that is supported by the terminal, and
wherein the call related information is related to at least a service type, Quality of Service (QoS) information, a target network radio technology, or a target cell.
2. The method of claim 1 , wherein the paging message is transmitted by a core network.
3. The method of claim 2 , wherein the core network is either a mobility management entity (MME) or a gateway (GW).
4. The method of claim 3 , wherein the GW is either a serving GW (sGW) or a packet data network GW (pGW).
5. The method of claim 1 , wherein the network is at least an enhanced Node B (eNB), a base station controller (BSC), a radio network controller (RNC) or a Node B (NB).
6. The method of claim 1 , wherein the terminal related information indicates a type of radio network technology that is supported by the terminal.
7. The method of claim 6 , wherein the radio network technology is at least a GSM (Global System for Mobile communications), a UMTS (Universal Mobile Telecommunications System) or an LTE (Long Term Evolution).
8. The method of claim 1 , wherein the terminal related information indicates a maximum uplink transmission rate or a maximum downlink transmission rate.
9. The method of claim 1 , wherein the terminal related information indicates whether the terminal supports a voice service or a data service.
10. The method of claim 1 , wherein the terminal related information indicates either a maximum amount of buffer in the terminal or a maximum number of channels supported by the terminal.
11. The method of claim 1 , wherein the terminal related information indicates a radio resource support amount for a radio bearer setup between the terminal and the network.
12. The method of claim 1 , wherein the paging message further includes a plurality of fields to store at least the call related information or the terminal related information.
13. The method of claim 1 , wherein the paging message further includes an identifier of the terminal (UE id) or a message type.
