Abstract

A method of handling service group creation for a personal network element of a communication system is disclosed. The method comprises obtaining existence information of service groups in the communication system when the personal network element is going to reside in a service group, and determining whether to create or join the service group according to the existence information.

Claims

1. A method of handling service group (SG) creation for a personal network element (PNE) of a communication system, the method comprising:

obtaining existence information of service groups in the communication system when the personal network element is going to reside in a service group; and

determining whether to create or join the service group according to the existence information.

2. The method of claim 1, wherein determining whether to create or join the service group according to the existence information comprises:

creating no service group when the existence information of the service groups indicates that the service group has been existed.

3. The method of claim 2, further comprising:

joining the service group.

4. The method of claim 1, wherein obtaining existence information of the service groups in the communication system when the personal network element is going to reside in the service group comprises:

transmitting a first message for querying existence information of the service groups, to a personal network of the communication system; and

receiving a second message including the existence information of the service groups and responding to the first message, from the personal network.

5. The method of claim 1, wherein the existence information comprises information of at least one of services provided by the existing service groups, service description, and personal network element identity.

6. The method of claim 1, wherein determining whether to create or join the service group according to the existence information comprises:

creating the service group when the existence information of the service groups indicates that the service group is not existed.

7. The method of claim 1, wherein determining whether to create or join the service group according to the existence information comprises:

creating the service group when the existence information of the service groups indicates that the service group has been existed.

8. A method of handling service group (SG) creation for a personal network of a communication system, the method comprising:

transmitting information associated to existence of service groups in the communication system, to at least a personal network element (PNE) in the personal network when the personal network elements register the personal network.

9. The method of claim 8, wherein the information is transmitted with a broadcast message or a dedicated message to the personal network element.

10. A method of handling service group (SG) creation for a personal network element (PNE) of a communication system, the method comprising:

creating a first service group when the personal network element is going to reside in the first service group;

obtaining existence information of service groups in the communication system; and

determining whether to delete the first service group according to the existence information.

11. The method of claim 10, wherein determining whether to delete the first service group according to the existence information comprises:

deleting the first service group when the existence information of the service groups indicates that a second service group providing the same service as the first service group has been existed.
