Group resource update processing method, device and system, and cse

Disclosed are a group resource update processing method, device and system, and a CSE. The method comprises: establishing group resources of a preset group, group members corresponding to the group resources comprising a member representative used for representing the group members; receiving a group resource update request that is sent by a remote common services entity (CSE) and that is used for performing an update operation on the group members corresponding to the group resources; and feeding the result of performing the update operation on the member representative, as a result of performing the update operation on all the group members, back to the remote CSE according to the group resource update request. By means of the present invention, the problem of network congestion caused by great signaling overheads required for performing batch operations on members in a group in the related art is solved, and accordingly, the effects of optimizing operations on group member attributes, effectively reducing signaling overheads and avoiding network congestion are achieved.
