METHOD, NETWORK SIDE DEVICE, TERMINAL DEVICE AND COMMUNICATION SYSTEM FOR CONTROLLING PACKET ACCESS

摘要

Provided in an embodiment of the present invention are a method, network side device, terminal device and communication system for controlling packet access. The method comprises: generating an access trigger message, the access trigger message carries a temporary mobile group identity (TMGI) allocated to a user equipment (UE); sending the access trigger message to packet trigger access operations of the UE for the TMGI. The embodiment of the present invention can use the existing TMGI in the multimedia broadcast multicast service (MBMS) as a group identity for the packet triggered UE access, and correspondingly generate and send the access trigger message carrying the TMGI for triggering access operations of the UE belonging to the TMGI, thus realizing the function of the packet triggering user access.
