Abstract

A method for a multi-host system to exit from the network includes receiving a G-MS exit network instruction. The context information relating to the host connected to the G-MS is obtained. A host exit network instruction is sent to the host network management entity according to the ID of the host network management entity. The host is triggered to exit from the network. The obtained host context information includes the ID of the host connected to the G-MS and the ID of the host network management entity. The exit network instruction carries the host ID.

Claims

1. A method of disconnecting hosts from a network, the method comprising:

receiving, by a Gateway Mobile Station (G-MS) management entity, a G-MS exit network instruction indicating that a gateway mobile station is exiting the network, wherein a plurality of host devices are using the gateway mobile station to connect to the network, the host devices being separate and distinct from the gateway mobile station, and wherein the G-MS exit network instruction includes a G-MS identifier (ID) of the gateway mobile station but excludes host identifiers (IDs) of the plurality of host devices using the gateway mobile station to connect to the network;

mapping, by the G-MS management entity, the G-MS ID to a host context information, wherein the host context information comprises the host IDs of the plurality of host devices and one or more host network management entity IDs of one or more host network management entities; and

sending, by the G-MS management entity, one or more host exit network instructions carrying the host IDs to the one or more host network management entities according to the one or more host network management entity IDs, wherein the one or more host exit network instructions initiate a process of disconnecting the plurality of host devices from the network.

2. The method according to claim 1, wherein mapping the G-MS ID to the host context information comprises:

mapping the G-MS ID to the host context information in accordance with a mapping relationship, wherein the mapping relationship was established, by the G-MS management entity when the host devices initially used the gateway mobile station to access the network.

3. The method according to claim 1, wherein the G-MS management entity is a G-MS authenticator and the host network management entity is a host Authentication, Authorization, and Accounting proxy;

or the G-MS management entity is a G-MS authenticator and the host network management entity is a host authenticator;

or the G-MS management entity is a G-MS anchor data path function (DPF) and the host network management entity is a host anchor DPF.

4. The method according to claim 3, wherein the G-MS exit network instruction is received from the gateway mobile station.

5. The method according to claim 3, wherein the G-MS exit network instruction is received from a G-MS Authentication, Authorization, and Accounting (AAA) server.

6. The method according to claim 3, wherein, after sending the host exit network instruction to the host network management entity, the method further comprises:

deleting, by the host network management entity, the host context information according to the host ID carried in the host exit network instruction.

7. The method of claim 1, wherein the host devices are incapable of accessing the network directly, and wherein the gateway mobile station provides the host devices with access to the network.

8. The method according to claim 1, wherein the host context information is excluded from the G-MS exit network instruction, wherein each of the host IDs are assigned exclusively to one of the plurality of hosts, wherein the G-MS ID is assigned exclusively to the gateway mobile station, and wherein the host IDs are different than the G-MS ID.

9. The method according to claim 1, wherein the G-MS management entity is a G-MS authenticator and the host network management entity is a host Authentication, Authorization, and Accounting proxy.

10. The method according to claim 1, wherein the G-MS management entity is a G-MS authenticator and the host network management entity is a host authenticator.

11. The method according to claim 1, wherein the G-MS management entity is a G-MS anchor data path function (DPF) and the host network management entity is a host anchor DPF.

12. The method according to claim 1, wherein the host IDs exclude the G-MS ID.

13. A Gateway Mobile Station (G-MS) management entity comprising:

a processor; and

a computer readable storage medium storing programming for execution by the processor, the programming including instructions to;

receive a G-MS exit network instruction indicating that a gateway mobile station is exiting the network, wherein a plurality of host devices are using the gateway mobile station to connect to the network, the host devices being separate and distinct from the gateway mobile station, and wherein the G-MS exit network instruction includes a G-MS identifier (ID) of the gateway mobile station but excludes host identifiers (IDs) associated with the plurality of host devices using the gateway mobile station to connect to the network;

map the G-MS ID to a host context information, wherein the host context information comprises the host IDs for the plurality of host devices and one or more host network management entity IDs of one or more host network management entities; and

send one or more host exit network instructions carrying the host IDs to the one or more host network management entities according to the one or more host network management entity IDs, wherein the one or more host exit network instructions initiate a process of disconnecting the plurality of host devices from the network.

14. The G-MS management entity of claim 13, wherein the host devices are incapable of accessing the network directly, and wherein the gateway mobile station provides the host devices with access to the network.

15. The G-MS management entity of claim 13, wherein the host context information is excluded from the G-MS exit network instruction, wherein each of the host IDs are assigned exclusively to one of the plurality of hosts, wherein the G-MS ID is assigned exclusively to the gateway mobile station, and wherein the host IDs are different than the G-MS ID.

16. The G-MS management entity of claim 13, wherein the host IDs exclude the G-MS ID.

17. The G-MS management entity of claim 13, wherein the G-MS management entity is a G-MS authenticator and the host network management entity is a host Authentication, Authorization, and Accounting proxy.

18. The G-MS management entity of claim 13, wherein the G-MS management entity is a G-MS authenticator and the host network management entity is a host authenticator.

19. The G-MS management entity of claim 13, wherein the G-MS management entity is a G-MS anchor data path function (DPF) and the host network management entity is a host anchor DPF.
