Abstract

Embodiments of the present invention provide a group communication method, system, group server, and group member device. A group server receives notification messages sent by a group member device, aggregates, according to an address of a subscription device, the notification messages destined for the same subscription device, and sends a notification message obtained after aggregation to the subscription device. By aggregating multiple messages sent by the group member device to the subscription device, messages exchanged between the group member device and the subscription device are reduced, thereby reducing communication traffic between the group member device and the subscription device.

3. The method according to claim 2, wherein the aggregating, according to a forwarding identifier and the address of the subscription device carried in the notification messages, the notification messages destined for the same subscription device comprises:

determining, according to the forwarding identifier carried in the notification messages, that the notification messages need to be forwarded to the subscription device; and

aggregating, according to the address of the subscription device carried in the notification messages, the notification messages that carry the same address of the subscription device into a single notification message.

4. The method according to claim 1, wherein the aggregating, according to an address of the subscription device, the notification messages destined for the same subscription device comprises:

aggregating, according to a recipient address of the notification messages and the address of the subscription device carried in the notification messages, the notification messages destined for the same subscription device.

5. The method according to claim 4, wherein the aggregating, according to a recipient address of the notification messages and the address of the subscription device carried in the notification messages, the notification messages destined for the same subscription device comprises:

determining, according to the recipient address of the notification messages, that the notification messages need to be forwarded to the subscription device, wherein the recipient address of the notification messages is an address of a subresource of the group server for aggregating notification messages; and

aggregating, according to the address of the subscription device carried in the notification messages, the notification messages that carry the same address of the subscription device into a single notification message.

6. The method according to claim 1, wherein the aggregating, according to an address of the subscription device, the notification messages destined for the same subscription device comprises:

aggregating, according to a recipient address of the notification messages and the address of the subscription device stored in a subresource of the group server, the notification messages destined for the same subscription device.

7. The method according to claim 6, wherein the aggregating, according to a recipient address of the notification messages and the address of the subscription device stored in a subresource of the group server, the notification messages destined for the same subscription device comprises:

determining, according to the recipient address of the notification messages, that the notification messages need to be forwarded to the subscription device, wherein the recipient address of the notification messages is an address of a subresource of the group server for aggregating notification messages;

acquiring, according to the recipient address of the notification messages, from the subresource of the group server corresponding to the recipient address of the notification messages, the address of the subscription device stored in the subresource; and

aggregating, according to the address of the subscription device, the notification messages with the same recipient address into a single notification message.

8. The method according to claim 7, further comprising:

receiving an address change request message sent by the subscription device, wherein the request message carries a changed address of the subscription device; and

updating the address of the subscription device stored in the subresource, to the changed address.

9. The method according to claim 6, before receiving notification messages sent by the group member device, further comprising:

receiving a request message sent by the subscription device for subscribing to a group member device of the group server, wherein the request message carries the address of the subscription device; and

creating, according to the request message, a subresource for storing the subscription condition set by the subscription device and the address of the subscription device.

10. The method according to claim 9, wherein a manner of creating a subresource for storing the subscription condition set by the subscription device and the address of the subscription device comprises either of the following manners:

manner 1;

searching, in a group resource, for a subresource that comprises the subscription condition set by the subscription device; and

if the subresource exists, creating, in the subresource, a subresource for storing the address of the subscription device;

or if the subresource does not exist, first creating, according to the subscription condition set by the subscription device, a subresource for storing the subscription condition, and then creating, in the subresource for storing the subscription condition, a subresource for storing the address of the subscription device; and

manner 2;
