Abstract

A method for transmitting and receiving a group messaging in a wireless communication system and an apparatus for the same is disclosed. Particularly, the method for receiving a group message performed by a user equipment (UE) in a wireless communication system include receiving assistance information indicating whether a paging message is transmitted for each UE group from a network node, receiving the paging message from the network node on a paging occasion of the UE, when the transmission of the paging message for a group to which the UE is belonged in indicated by the assistance information, and receiving the group message, when a group message transmission for the group to which the UE is belonged is activated by the paging message.

Claims

1. A method for receiving a group message performed by a user equipment (UE) in a wireless communication system, comprising:

receiving assistance information indicating whether a paging message is transmitted for each UE group from a network node;

receiving the paging message from the network node on a paging occasion of the UE, when the transmission of the paging message for a group to which the UE is belonged is indicated by the assistance information; and

receiving the group message, when a group message transmission for the group to which the UE is belonged is activated by the paging message.

2. The method for receiving a group message of claim 1, wherein the assistance information is transmitted through a system information message or a common control channel.

3. The method for receiving a group message of claim 1, wherein the assistance information indicates a group identity allocated to each UE group or a modular value for an International Mobile Subscriber Identity (IMSI) for the UE.

4. The method for receiving a group message of claim 1, wherein the assistance information indicates a group message discriminating number which is predetermined for each UE group.

5. The method for receiving a group message of claim 4, wherein the group message discriminating number is configured through an attach procedure or a tracking area update procedure.

6. The method for receiving a group message of claim 1, wherein the group message is transmitted through a system information message.

7. A method for transmitting a group message performed by a network node in a wireless communication system, comprising:

transmitting a group message indication indicating whether a group message is transmitted and assistance information for identifying for which user equipment (UE) group the group message is to a UE; and

transmitting the group message to the UE,

wherein whether the UE receives the group message is determined based on the group message indication and the assistance information.

8. The method for transmitting a group message of claim 7, wherein the group message indication is transmitted through a paging message.

9. The method for transmitting a group message of claim 7, wherein the assistance information is transmitted through a paging message, a system information message or a common control channel.
