Abstract

A message transmission control method, including: a location node storing a message transmission control list of a terminal node; after the terminal node registers to an access node, the access node requesting the location node to send the message transmission control list of the terminal node; the location node searching for the message transmission control list of the terminal node, and sending to the access node; and after receiving the message transmission control list of the terminal node, the access node filtering data messages sent to the terminal node according to the message transmission control list. The present invention also provides a message transmission control system, and a register/update method and system. The control of the message transmission control list in the present invention is implemented in the access server of the wireless network, thus to avoid the wireless resource waste and the subscriber charge loss.

First claim

What is claimed is:

1. A message transmission control method, comprising:
a first location node storing a message transmission control list of a second terminal node;
after the second terminal node registers to a second access node, the second access node requesting the first location node to send the message transmission control list of the second terminal node;
the first location node searching for the message transmission control list of the second terminal node, and sending to the second access node; and
after receiving the message transmission control list of the second terminal node, the second access node filtering data messages sent to the second terminal node according to the message transmission control list;
wherein when the second terminal node registers to another access node afterwards, said first location node further sends said message transmission control list of the second terminal node to said another access node;
wherein the message transmission control list comprises one or more subscriber identifications (SID);
the step of the second access node filtering the data messages sent to the second terminal node comprises:
after receiving the data message, the second access node searching out the corresponding message transmission control list according to the destination SID of the data message; and
comparing the source SID of the data message with the SIDs in the message transmission control list: if the source SID exists in the message transmission control list, discarding the received data message;
thereby data messages sent from terminals whose SIDs are in said message transmission control list of the second terminal node to the second terminal node are discarded by the second access node;
wherein a subscriber of the second terminal node is able to modify or delete said message transmission control list of the second terminal node, when the subscriber modifies the message transmission control list, the message transmission control list in the first location node is updated, and the first location node retrieves a location of the second terminal node, and sends the updated message transmission control list to the access node where the second terminal node is located, said access node updates the message transmission control list of the second terminal node and filters data messages according to the updated message transmission control list.

2. The method of claim 1 , wherein, after the step of the first location node storing the message transmission control list of the second terminal node, the method further comprises:
deleting the message transmission control list stored in the first location node;
the first location node sending an empty message transmission control list to an access node to which the second terminal node currently accesses; and
after receiving the empty message transmission control list, the access node deleting the stored message transmission control list of the second terminal node, and removing the filtering of the data messages sent to the second terminal node.

3. The method of claim 1 , wherein:
the second access node requests the first location node to send the message transmission control list of the second terminal node by forwarding a registration request message of the second terminal node to the first location node;
the first location node sends the message transmission control list of the second terminal node to the second access node via a registration successful message.

4. A message transmission control system, comprising: a second terminal node comprising a hardware processor, a second access node comprising a hardware processor and a first location node comprising a hardware processor, wherein:
the first location node is set to: store a message transmission control list of the second terminal node, and after receiving a request from the second access node, search for the message transmission control list of the second terminal node, and send to the second access node;
the second access node is set to: after the second terminal node finishes registration, request the first location node to send the message transmission control list of the second terminal node; and after receiving the message transmission control list of the second terminal node, filter data messages sent to the second terminal node according to the message transmission control list;
wherein when the second terminal node registers to another access node afterwards, said first location node further sends said message transmission control list of the second terminal node to said another access node;
wherein the message transmission control list comprises one or more subscriber identifications (SID);
the second access node filters the data messages sent to the second terminal node comprises:
after receiving the data message, the second access node searching out the corresponding message transmission control list according to the destination SID of the data message; and
comparing the source SID of the data message with the SIDs in the message transmission control list: if the source SID exists in the message transmission control list, discarding the received data message;
thereby data messages sent from terminals whose SIDs are in said message transmission control list of the second terminal node to the second terminal node are discarded by the second access node;
wherein a subscriber of the second terminal node is able to modify or delete said message transmission control list of the second terminal node, when the subscriber modifies the message transmission control list, the message transmission control list in the first location node is updated, and the first location node retrieves a location of the second terminal node, and sends the updated message transmission control list to the access node where the second terminal node is located, said access node updates the message transmission control list of the second terminal node and filters data messages according to the updated message transmission control list.

5. A network access device, comprising a hardware processor that is configured to perform steps in the following modules:
a terminal node registering module, which is set to: complete the registration of the terminal node;
a transmission requesting module, which is set to: after the terminal node finishes the registration, request a location node which stores a message transmission control list of the terminal node to send the message transmission control list of the terminal node; and
a receiving filtering module, which is set to: after receiving the message transmission control list of the terminal node, filter data messages sent to the terminal node according to the message transmission control list;
wherein when the terminal node registers to another access node device afterwards, said location node further sends said message transmission control list of the terminal node to said another access node device;
wherein the message transmission control list comprises one or more subscriber identifications (SID);
filtering the data messages sent to the terminal node comprises:
after receiving the data message, searching out the corresponding message transmission control list according to the destination SID of the data message; and
comparing the source SID of the data message with the SIDs in the message transmission control list: if the source SID exists in the message transmission control list, discarding the received data message;
thereby data messages sent from terminals whose SIDs are in said message transmission control list of the terminal node to the terminal node are discarded by the network access device;
wherein a subscriber of the terminal node is able to modify or delete said message transmission control list of the terminal node, when the subs
