Abstract
A method for a network side to logout a mobile station (MS) in an idle mode is provided. The method includes receiving, by a paging agent of network side entities, a location update request message carrying a power-off indication sent from the MS; sending, by the paging agent, a location update confirm message, to an anchor paging controller/location register of the network side entities. According to the location update confirm message, the anchor paging controller/location register triggers at least one network side entity of the network side entities to release resources associated with the MS and delete a context of the MS stored in the at least one network side entity. Accordingly, the system resources are saved.
Claims13
A method for network side equipment to logout a mobile station in an idle mode, wherein the network side equipment comprises a plurality of network entities, the method comprising:
- receiving, by a paging agent of the plurality of network entities, a ranging request message carrying a power-off indication from the mobile station;
- verifying, by the paging agent, the ranging request message according to an authentication key and an authentication key context of the mobile station;
- after successfully verifying the ranging request message, sending a location update confirm message from the paging agent to an anchor paging controller/location register of the plurality of network entities;
- according to the location update confirm message sending a first message indicating the mobile station is power-off from the anchor paging controller/location register to an anchor data path function entity/foreign agent function entity of the plurality of network entities;
- according to the first message indicating the mobile station is power-off, initiating, by the anchor data path function entity/foreign agent function entity, a mobile IP address de-registration operation upon the mobile station, deleting a context of the mobile station stored in the anchor data path function entity/foreign agent function entity and sending a second message in response to the first message to the anchor paging controller/location register;
- and
- according to the second message, deleting, by the anchor paging controller/location register a context of the mobile station stored in the anchor paging controller/location register.
A system for network side equipment to logout a mobile station in an idle mode, comprising a plurality of network entities serving the mobile station,
- wherein the plurality of network entities include an paging agent, an anchor data path function entity/foreign agent function entity and an anchor paging controller/location register;
- wherein the paging agent is configured to receive a ranging request message carrying a power-off indication from the mobile station, to verify the ranging request message according to an authentication key and an authentication key context of the mobile station, and to send a location update confirm message to the anchor paging controller/location register after successfully verifying the request message;
- wherein the anchor paging controller/location register is configured to, according to the location update confirm message, send a first message indicating the mobile station is power-off, to the anchor data path function entity/foreign agent function entity;
- wherein the anchor data path function entity/foreign agent function entity is configured to, according to the first message indicating the mobile station is power-off, initiate a mobile IP address de-registration operation upon the mobile station, to delete a context of the mobile station stored in the anchor data path function entity/foreign agent function entity and to send a second message in response to the first message to the anchor paging controller/location register;
- and
- wherein the anchor paging controller/location register is further configured to, according to the second message, delete a context of the mobile station stored in the anchor paging controller/location register.
