Abstract

A method for allocating an identification using an access network grouping scheme, and a method and apparatus for paging group are described. The ID allocating method comprises: receiving a group ID of a group of group-paged objects allocated by a core network device for a terminal device, wherein the group of group-paged objects comprises one or more subgroups; allocating a device ID or a user ID to the terminal device, wherein the device ID or the user ID comprises information of a subgroup ID of a subgroup to which the terminal device belongs; and sending the allocated device ID or user ID to the terminal device. The number of terminals in the subgroup is appropriate, and the resources are allocated more flexibly and reasonably.

Claims

1. A method for allocating an identification (ID) to a terminal device to facilitate group paging, comprising:

receiving a group ID for the terminal device, wherein the group ID corresponds to a group of group-paged objects, wherein the group ID is allocated by a core network device, and wherein the group of the group-paged objects comprises one or more subgroups;

allocating, by a network device, a device ID or a user ID for the terminal device, wherein the device ID or the user ID comprises information of a subgroup ID of a subgroup to which the terminal device belongs; and

sending the allocated device ID or user ID to the terminal device.

2. The method according to claim 1, wherein the device ID or the user ID further comprises the group ID for the terminal device.

3. The method according to claim 2, wherein the allocating the device ID or the user ID for the terminal device comprises:

mapping the group ID to a bit corresponding to the device ID or the user ID; and

storing mapping information.

4. The method according to claim 1, wherein the allocating the device ID or the user ID for the terminal device comprises at least one of:

mapping the group ID into the device ID or the user ID;

mapping a cell ID of a cell to which the terminal device belongs into the device ID or the user ID;

mapping the subgroup ID of the subgroup to which the terminal device belongs into the device ID or the user ID;

or

mapping a specific ID of the terminal device into the device ID or the user ID.

5. A method for group paging, comprising:

receiving a group paging request from a core network device, wherein the group paging request comprises a group identification (ID) of a group of group-paged objects;

determining the number of terminal devices belonging to the group of group-paged objects in a cell supported by an access network device according to the group ID;

grouping the terminal devices into one or more subgroups based on the number of terminal devices;

determining a subgroup ID corresponding to a subgroup of the one or more subgroups;

generating a group paging message carrying the subgroup ID; and

sending the group paging message.

6. The method according to claim 5, wherein the grouping the terminal devices into one or more subgroups based on the number of terminal devices comprises:

acquiring load data of the cell;

requesting service subscription data from the core network device according to the group ID;

determining subgroup size based on the load data and the service subscription data; and

determining the number of subgroups based on the determined subgroup size and the number of terminal devices.

7. The method according to claim 6, wherein the terminal devices each have a device ID or a user ID, the device ID or the user ID comprising information of a subgroup ID of a subgroup to which the corresponding terminal device belongs, and

wherein determining the subgroup ID comprises determining, based on the determined subgroup size and the determined number of the subgroups, the subgroup ID from the device ID or the user ID.

8. A method group paging, comprising:

receiving a group paging message generated by an access network device via monitoring a paging channel, wherein the group paging message carries a subgroup identification (ID) determined by the access network device;

obtaining the subgroup ID from the group paging message;

determining whether the subgroup ID matches a stored device ID or user ID; and

responding to the group paging message in response to determining that the subgroup ID matches the stored device ID or user ID.

9. The method according to claim 8, wherein the stored device ID or user ID comprises information of a subgroup ID of a subgroup to which the terminal device belongs.

10. A communication device, comprising:

a receiver configured to receive a group identification (ID) for a terminal device, wherein the group ID corresponds to a group of group-paged objects, wherein the group ID is allocated by a core network device, and wherein the group of group-paged objects comprises one or more subgroups;

a processor configured to allocate a device ID or a user ID for the terminal device, wherein the device ID or the user ID comprises information of a subgroup ID of a subgroup to which the terminal device belongs; and

a transmitter configured to send the allocated device ID or user ID to the terminal device.

11. The communication device according to claim 10, wherein the device ID or the user ID further comprises the group ID for the terminal device.

12. The communication device according to claim 11, wherein the processor is further configured to map the group ID to a bit corresponding to the device ID or the user ID;

and store mapping information.

13. The communication device according to claim 10, wherein the processor is further configured to map at least one of:

the group ID, a cell ID of a cell to which the terminal device belongs, the subgroup ID of the subgroup to which the terminal device belongs, or a specific ID of the terminal device, into the device ID or the user ID.

14. A communication device, comprising:

a receiver configured to receive a group paging request from a core network device, wherein the group paging request comprises a group identification (ID) of a group of group-paged objects;

a processor configured to determine the number of terminal devices belonging to the group of group-paged objects in a cell supported by an access network device according to the group ID;

configured to group the terminal devices into one or more subgroups based on the number of terminal devices;

configured to determine a subgroup ID corresponding to a subgroup of the one or more subgroups; and

configured to generate a group paging message carrying the subgroup ID; and

a transmitter configured to send the group paging message.

15. The communication device according to claim 14, wherein the processor is further configured to acquire load data of the cell;

configured to request service subscription data from the core network device according to the group ID;

configured to determine subgroup size based on the load data and the service subscription data; and

configured to determine the number of subgroups based on the determined subgroup size and the number of terminal devices.

16. The communication device according to claim 15, wherein the terminal devices each have a device ID or a user ID, the device ID or the user ID comprising information of a subgroup ID of a subgroup to which the corresponding terminal device belongs,

wherein the processor is further configured to determine, based on the determined subgroup size and the determined number of subgroups, the subgroup ID from the device ID or the user ID.

17. A communication device, comprising:

a receiver configured to receive a group paging message generated by an access network device via monitoring a paging channel, wherein the group paging message carries a subgroup identification (ID) determined by the access network device;

a processor configured to obtain the subgroup ID from the group paging message and determine whether the subgroup ID matches a stored device ID or user ID; and
