Abstract

A method and device for creating service groups and sharing objects within the service groups in a CPNS enabler are discussed. According to an embodiment, a method includes transmitting a first request to create a new CPNS service group to the CPNS server; receiving a second request to provide member information for the CPNS service group from the CPNS server in response to the first request; transmitting the member information for the CPNS service group to the CPNS server in response to the second request, the member information being used to create the CPNS service group and being stored in association with the CPNS service group in the CPNS server; and receiving a response indicating the creation of the CPNS service group from the CPNS server.

First claim

The invention claimed is:

1. A method for managing a service group in a converged personal network service (CPNS) enabler, the CPNS enabler including a CPNS server and a plurality of CPNS entities, the method performed by a CPNS device and comprising:
transmitting, by the CPNS device, a first request to create a first CPNS service group to the CPNS server, wherein the first request includes a CPNS service group number and an object to be shared in the first CPNS service group,
wherein a service group table is created by the CPNS server using the CPNS service group number and the object to be shared in the first CPNS service group which are included in the first request when the first request is received, the service group table indicating a relationship between the object to be shared in the first CPNS service group and the CPNS service group number, and the service group table further indicating a condition for sharing the object within the first CPNS service group;
receiving, by the CPNS device, a second request to provide member information for the first CPNS service group from the CPNS server in response to the first request;
transmitting, by the CPNS device, the member information for the first CPNS service group to the CPNS server in response to the second request, wherein the member information identifies one or more CPNS entities that belong to the first CPNS service group,
wherein a device service group table is created by the CPNS server using the member information received from the CPNS device when the member information for the first CPNS service group is received, the device service group table indicating a relationship between the first CPNS service group and the one or more CPNS entities;
receiving, by the CPNS device, a first response indicating the creation of the first CPNS service group from the CPNS server;
transmitting, by the CPNS device, administrator information for the first CPNS service group to the CPNS server, wherein the administrator information identifies at least one of the one or more CPNS entities,
wherein an administrator service group table is created by the CPNS server using the administrator information received from the CPNS device when the administrator information is received, the administrator service group table indicating that the at least one of the one or more CPNS entities is designated to be an administrator of the first CPNS service group, and the administrator service group table further indicating rights that each of the administrators of the first CPNS service group has;
in response to determining that the condition indicated by the service group table indicates that an authorization of the administrator is required for sharing the object within the first CPNS service group, the CPNS server:
refers to the administrator service group table to identify the administrator of the first CPNS service group, and
checks whether the administrator has rights to authorize the sharing of the object;

in response to determining that the administrator has rights to authorize the sharing of the object, the CPNS server further:
communicates with the administrator of the first CPNS service group to receive approval or denial of sharing the object within the first CPNS service group, and
transmits a first notification to the CPNS device that the object can be shared within the first CPNS service group;

sharing, by the CPNS device, the object within the first CPNS service group based on the first notification received from the CPNS server;
receiving, by the CPNS server, a third request for removing a first CPNS entity from the first CPNS service group;
in response to receiving the third request, the CPNS server:
refers to the device service group table and the administrator service group table to identify an administrator of the first CPNS service group,
communicates with the administrator of the first CPNS service group to receive approval or denial of the third request from the administrator of the first CPNS service group,
updates the device service group table when the third request is approved, and
transmits a second notification indicating a change of the device service group table to members of the first CPNS service group with reference to the updated device service group table;

receiving, by the CPNS device, the second notification from the CPNS server, wherein the object is no longer shared with the first CPNS entity within the first CPNS service group based on the second notification received from the CPNS server;
receiving, by the CPNS server, a fourth request from a second CPNS entity for removing a first object from being shared with a second CPNS service group; and
in response to receiving the fourth request, the CPNS server:
refers to the service group table to check whether the fourth request is allowed,
updates the service group table such that the first object is not shared with the second CPNS service group,
sends a change notification of the service group table to members of the second CPNS service group except for the second CPNS entity, and
sends a second response to the second CPNS entity without the change notification.

2. The method of claim 1 , further comprising:
transmitting a specific content and a fifth request to share the specific content with the first CPNS service group to the CPNS server, the specific content being stored in association with the first CPNS service group in the CPNS server.

3. The method of claim 2 , further comprising:
receiving, from the CPNS server, a third response indicating whether the specific content was shared with the first CPNS service group.

4. The method of claim 1 , further comprising:
transmitting service group information for the first CPNS service group to the CPNS server, the service group information being stored in association with the first CPNS service group in the CPNS server.

5. The method of claim 4 , wherein the service group information includes authorization information identifying how a request for the first CPNS service group is to be processed.

6. The method of claim 5 , further comprising:
receiving a request to authorize a sixth request to share a content with the first CPNS service group, from the CPNS server; and
transmitting a confirmation response to the sixth request to the CPNS server.

7. The method of claim 1 , wherein the CPNS device is a gateway or a personal network element (PNE).

8. A method for managing a service group in a converged personal network service (CPNS) enabler, the CPNS enabler including a CPNS server and a plurality of CPNS entities, the method performed by the CPNS server and comprising:
receiving, by the CPNS server, a first request to create a first CPNS service group from a CPNS device, wherein the first request includes a CPNS service group number and an object to be shared in the first CPNS service group,
wherein a service group table is created by the CPNS server using the CPNS service group number and the object to be shared in the first CPNS service group which are included in the first request when the first request is received, the service group table indicating a relationship between the object to be shared in the first CPNS service group and the CPNS service group number, and the service group table further indicating a condition for sharing the object within the first CPNS service group;
transmitting, by the CPNS server, a second request to provide member information for the first CPNS service group to the CPNS device in response to the first request;
receiving, by the CPNS server, the member information for the first CPNS service group from the CPNS device in response to the second request, wherein the member information identifies one or more CPNS entitie
