METHOD AND SYSTEM FOR MESSAGE TRANSMISSION CONTROL, METHOD AND SYSTEM FOR REGISTER/UPDATE

摘要

A message transmission control method includes the steps: a location node stores a message transmission control list of a terminal node; after the terminal node has registered on an access node, the access node requests the location node to transmit the message transmission control list of the terminal node; the location node searches for the message transmission control list of the terminal node and transmits it to the access node; and after receiving the message transmission control list of the terminal node, the access node, based on the message transmission control list, filters data messages transmitted to the terminal node. The invention also provides a message transmission control system, a register/update method and the system thereof. The control for the message transmission control list of the invention is implemented in an access server of a wireless network, thus the wireless resource waste and the subscriber charge loss are avoided. Furthermore, the message transmission control list is stored in the location server of mobile subscribers, which supports the roaming and handover of the mobile data subscriber.
