Abstract

The present invention relates to the communication field and discloses a method for managing devices in a user network and a user network management entity which handles combining and splitting operations in the user network more efficiently. In the technical solution provided by the present invention, the management entity of the user network obtains the information about the location of the managed PANs and/or stand-alone devices, and, based on the location information, checks existence of any PAN and/or stand-alone device that can be combined or split. If any such device exists, the management entity performs the combining or splitting operation according to the combining or splitting mode preset or selected by the user. In the process of combining or splitting a PAN or stand-alone device, the user can reserve the network registration information of some relevant devices as required, update the network registration information of other devices directly, and switch the service access points to ensure continuity of network services.

Claims

1. A method for managing devices in a user network, comprising:

obtaining, by a management entity, current location information of each management object in the user network;

judging whether the management objects meet the preset conditions of combining or splitting according to the obtained current location information; and

combining or splitting the management objects that meet the conditions.

2. The method according to claim 1, wherein:

the management object is a stand-alone device and/or a PAN managed by the management entity;

the PAN contains a management device capable of identifying access networks and other ordinary devices; and

the stand-alone device is capable of identifying access networks.

3. The method according to claim 2, wherein the combining operation is any of:

combining PANs, combining stand-alone devices, or combining a stand-alone device with a PAN.

4. The method according to claim 3, wherein the operation of combining PANs comprises:

specifying, by a management entity, a device as a management device for the combined PAN among the PANs involved in the combination;

updating network registration information of the specified management device;

updating network registration information of the devices in the PANs involved in the combination, except the devices in the PAN previously containing the specified management device;

switching the service access points of the devices in the PANs involved in the combination, except the devices in the PAN previously containing the specified management device, onto the specified management device; and

disabling the access network identification function of the management devices in the PANs involved in the combination, except the management devices in the PAN previously containing the specified management device.

5. The method according to claim 3, wherein the operation of combining a stand-alone device with a PAN comprises:

specifying, by a management entity, a management device of a combined PAN;

updating, by the management entity, the network registration information of the specified management device and the combined stand-alone device if the specified management device is a device in the PAN being combined;

switching the service access point of the stand-alone device being combined onto the specified management device; and

disabling the access network identification function of the stand-alone device; and

updating, by the management entity, the network registration information of all devices in the PAN being combined and the stand-alone devices if the specified management device is the stand-alone device being combined;

switching the service access points of all devices in the PAN being combined onto the specified management device; and

disabling the access network identification function of the management device in the PAN being combined.

6. The method according to claim 3, wherein the operation of combining stand-alone devices comprises:

specifying, by a management entity, a stand-alone device being combined as a management device for the combined PAN; and

updating the network registration information of the stand-alone devices; and

switching the service access points of the stand-alone devices involved in the combination, except the service access points of the specified stand-alone device, onto the specified management device; and

disabling the access network identification function of the stand-alone devices involved in the combination, except the access network identification function of the specified stand-alone device.

7. The method according to claim 2, wherein the splitting operation is:

splitting a PAN into two or more PANs, splitting a PAN into a stand-alone device and a PAN, or splitting a PAN into multiple stand-alone devices.

8. The method according to claim 7, wherein the process of splitting a PAN into two or more PANs comprises:

specifying, by a management entity, a management device for the split PANs;

updating the network registration information of the devices in the split PANs; and

switching the service access points of the ordinary devices in the split PAN onto the specified management device.

9. The method according to claim 7, wherein the process of splitting a PAN into a stand-alone device and a PAN comprises:

updating, by the management entity, the network registration information of the management device if the management device previously contained in the PAN is split into a stand-alone device;

specifying a management device for the split PAN;

updating the network registration information of the devices in the split PAN; and

switching the service access points of ordinary devices in the split PAN onto the specified management device.

10. The method according to claim 7, wherein the process of splitting a PAN into a stand-alone device and a PAN comprises:

updating, by the management entity, the network registration information of the management device and the split stand-alone device if the ordinary devices previously contained in the PAN is split into stand-alone devices.

11. The method according to claim 7, wherein the process of splitting a PAN into multiple stand-alone devices comprises:

updating the network registration information of the split stand-alone devices.

12. The method according to claim 4, wherein the network registration information includes one or more of a device identity, a network address, and a neighbor list.

13. The method according to claim 1, wherein the management entity obtains the location information of the management object in a preset period, as triggered by an event, or as originated by the user.

14. A user network management entity, comprising:

a location obtaining module, adapted to obtain location information of each management object in the user network;

a judging module, adapted to judge whether the management objects meet the preset conditions of combining or splitting according to the current location information obtained by the location obtaining module; and

an executing module, adapted to instruct the management object to execute the combining or splitting operation; and

instruct the management object that meets the conditions to execute the combining or splitting operation according to the judgment result of the judging module.

15. The user network management entity according to claim 14, wherein:

the management object is a stand-alone device and/or a PAN managed by the management entity;

the PAN contains a management device capable of identifying access networks and ordinary devices; and

the stand-alone device is capable of identifying access networks.
