Abstract

A communication method is disclosed, the operations including: receiving data that is sent by a terminal through a base station, where the data includes an identifier of a receive end and to-be-sent information, the receive end and the terminal are located in a mobile local access network MLAN, and the MLAN is a local access network established based on a wireless cellular network; and sending, based on an MLAN address corresponding to the identifier of the receive end, the to-be-sent information to the receive end through the base station.

First claim

What is claimed is:

1 . A communication method, comprising:
receiving data that is sent by a terminal through a base station, wherein the data comprises an identifier of a receive end and to-be-sent information, the receive end and the terminal are located in a mobile local access network (MLAN), and the MLAN is a local access network established based on a wireless cellular network; and sending, based on an MLAN address corresponding to the identifier of the receive end, the to-be-sent information to the receive end through the base station.

2 . The method according to claim 1 , wherein a process of establishing the MLAN comprises:
receiving an identifier that is of the terminal and that is sent by the terminal through the base station; and allocating, to the terminal, an MLAN address corresponding to the identifier of the terminal.

3 . The method according to claim 2 , wherein the process of establishing the MLAN further comprises:
allocating, to the terminal, a tunnel corresponding to the identifier of the terminal; and sending information about the tunnel to the terminal through the base station.

4 . The method according to claim 3 , wherein the receiving data that is sent by a terminal through a base station comprises:
receiving the data that is encapsulated in the tunnel and that is sent by the terminal through the base station.

5 . The method according to claim 3 , wherein the allocating, to the terminal, an MLAN address corresponding to the identifier of the terminal comprises:
if it is determined, based on the identifier of the terminal, that the terminal is valid, allocating, to the terminal, the MLAN address corresponding to the identifier of the terminal; and the allocating, to the terminal, a tunnel corresponding to the identifier of the terminal comprises: if it is determined, based on the identifier of the terminal, that the terminal is valid, allocating, to the terminal, the MLAN address corresponding to the identifier of the terminal.

6 . The method according to claim 1 , further comprising:
receiving information about a destination base station to which the terminal is handed over, wherein the information about the destination base station is sent by the destination base station if the terminal is handed over from a source base station to the destination base station; and updating, from the source base station to the destination base station, the base station used to send the to-be-sent information to the receive end.

7 . The method according to claim 1 , further comprising:
receiving a request for releasing the MLAN that is sent by the terminal through the base station; and releasing the MLAN address and/or the tunnel that correspond/corresponds to the identifier of the terminal.

8 . A communication method, comprising:
sending an identifier of a terminal through a base station, wherein the identifier of the terminal is used to obtain an MLAN address, the MLAN address is used to communicate with a device in a mobile local access network MLAN, and the MLAN is a local access network established based on a wireless cellular network; and sending data through the base station, wherein the data comprises an identifier of a receive end and to-be-sent information, and the receive end and the terminal are located in the MLAN.

9 . The method according to claim 8 , further comprising:
sending, through the base station, a request for releasing the MLAN, wherein the request for releasing the MLAN is used by the MLAN to release an MLAN address and/or a tunnel that correspond/corresponds to the identifier of the terminal.

10 . A communication apparatus, comprising:
at least one processor and a communication interface circuitry, wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from a memory to perform operations comprising: receiving data that is sent by a terminal through a base station, wherein the data comprises an identifier of a receive end and to-be-sent information, the receive end and the terminal are located in a mobile local access network (MLAN), and the MLAN is a local access network established based on a wireless cellular network; and sending, based on an MLAN address corresponding to the identifier of the receive end, the to-be-sent information to the receive end through the base station.

11 . The apparatus according to claim 10 , wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from the memory to perform operations comprising a process of establishing the MLAN, comprises:
receiving an identifier that is of the terminal and that is sent by the terminal through the base station; and allocating, to the terminal, an MLAN address corresponding to the identifier of the terminal.

12 . The apparatus according to claim 11 , wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from the memory to perform operations comprising the process of establishing the MLAN, further comprises:
allocating, to the terminal, a tunnel corresponding to the identifier of the terminal; and sending information about the tunnel to the terminal through the base station.

13 . The apparatus according to claim 12 , wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from the memory to perform operations comprising: the receiving data that is sent by a terminal through a base station, comprises:
receiving the data that is encapsulated in the tunnel and that is sent by the terminal through the base station.

14 . The apparatus according to claim 12 , wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from the memory to perform operations comprising: the allocating, to the terminal, an MLAN address corresponding to the identifier of the terminal, comprises:
if it is determined, based on the identifier of the terminal, that the terminal is valid, allocating, to the terminal, the MLAN address corresponding to the identifier of the terminal; and the allocating, to the terminal, a tunnel corresponding to the identifier of the terminal comprises: if it is determined, based on the identifier of the terminal, that the terminal is valid, allocating, to the terminal, the MLAN address corresponding to the identifier of the terminal.

15 . The apparatus according to claim 10 , wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from the memory to perform operations comprising:
receiving information about a destination base station to which the terminal is handed over, wherein the information about the destination base station is sent by the destination base station if the terminal is handed over from a source base station to the destination base station; and updating, from the source base station to the destination base station, the base station used to send the to-be-sent information to the receive end.

16 . The apparatus according to claim 11 , wherein the at least one processor cooperates with the communication interface circuitry, configured to invoke a program instruction from the memory to perform operations comprising:
receiving a request for releasing the MLAN that is sent by the terminal through the base station; and releasing the MLAN address and/or the tunnel
