Abstract

An antenna communication method and device are provided. The antenna communication method includes: establishing a communication tunnel between a Customer Premises Equipment (CPE) and a mobile terminal; receiving, by the CPE, a first request message sent by the mobile terminal; receiving, by the CPE, first communication data of the mobile terminal through the communication tunnel after receiving the first request message, and sending the first communication data to the BS according to the air interface connection information in the first request message; and receiving, by the CPE, second communication data sent by the BS according to the air interface connection information in the first request message, and sending the second communication data to the mobile terminal through the communication tunnel.

First claim

What is claimed is:

1. A wireless communication method, comprising:
establishing, by a Customer Premises Equipment (CPE), a communication tunnel with a mobile terminal;
receiving, by the CPE, a first request message sent by the mobile terminal, wherein the first request message comprises air interface connection information between the mobile terminal and a base station (BS) with which the CPE is attached, and determining, using a network identification (ID) of a wireless network in the first request message, that the mobile terminal and the CPE are located in the wireless network;
receiving, by the CPE, first communication data of the mobile terminal through the communication tunnel after receiving the first request message, and sending the first communication data to the BS according to the air interface connection information in the first request message; and
receiving, by the CPE, second communication data sent by the BS according to the air interface connection information in the first request message, and sending the second communication data to the mobile terminal through the communication tunnel, and
wherein before the establishing, by the CPE, the communication tunnel with the mobile terminal, the method further comprises:
sending, by the CPE, an information frame carrying wireless network information to the mobile terminal, wherein the wireless network information comprises an ID of the wireless network and an ID of the BS of the wireless network where the CPE is attached, so that the mobile terminal determines that the BS where the mobile terminal is attached is the same as the BS where the CPE is attached before sending the first request message.

2. The method according to claim 1 , wherein before the establishing, by the CPE, the communication tunnel with the mobile terminal, the method further comprises:
sending, by the CPE, an information frame carrying wireless network information to the mobile terminal, wherein the wireless network information comprises an ID of the wireless network and an ID of the BS of the wireless network where the CPE is attached;
receiving a ranging request for wireless network collision sent by the mobile terminal through the communication tunnel, wherein the ranging request for wireless network collision is sent by the mobile terminal according to the ID of the BS of the wireless network where the CPE is attached when the mobile terminal determines that the BS where the mobile terminal is attached is different from the BS where the CPE is attached;
sending the ranging request to the BS where the CPE is attached in a contention period of the BS, so that the BS where the CPE is attached implements, for the mobile terminal, a switch process from the BS where the mobile terminal currently attached to the BS where the CPE is attached or an initial access process;
receiving a ranging response message sent by the BS where the CPE is attached, wherein the ranging response message comprises air interface connection information allocated for the mobile terminal by the BS where the CPE is attached; and
sending the ranging response message to the mobile terminal through the communication tunnel.

3. The method according to claim 1 , wherein before the establishing, by the CPE, the communication tunnel with the mobile terminal, the method further comprises:
receiving, by the CPE, a connection request of the mobile terminal;
allocating, by the CPE, an IP address for the mobile terminal; and
sending, by the CPE, the IP address to the mobile terminal;
the establishing, by the CPE, the communication tunnel with the mobile terminal specifically comprises:
establishing, by the CPE, the communication tunnel with the mobile terminal according to the IP address allocated for the mobile terminal and the IP address of the CPE.

4. The method according to claim 1 , wherein the air interface connection between the mobile terminal and the BS comprises an uplink air interface connection of the mobile terminal and a downlink air interface connection of the mobile terminal, and after the CPE receives the first request message sent by the mobile terminal, the method further comprises:
establishing an uplink buffer queue for the uplink air interface connection of the mobile terminal; and
establishing a downlink buffer queue for the downlink air interface connection of the mobile terminal;
the receiving, by the CPE, the first communication data of the mobile terminal through the communication tunnel specifically comprises:
receiving an uplink Media Access Control (MAC) frame of the wireless network air interface sent by the mobile terminal through the communication tunnel, and buffering the uplink MAC frame in the corresponding uplink buffer queue;
the sending the first communication data to the BS according to the air interface connection information in the first request message specifically comprises:
intercepting an uplink mapping table (ULMAP) of the BS, and sending the uplink MAC frame in the uplink buffer queue in an uplink air interface connection time of the mobile terminal indicated in the ULMAP;
the receiving, by the CPE, the second communication data sent by the BS according to the air interface connection information in the first request message specifically comprises:
intercepting a downlink mapping table (DLMAP), receiving the downlink MAC frame delivered by the BS in a downlink air interface connection time of the mobile terminal indicated in the DLMAP, and storing the received downlink MAC frame in the corresponding downlink buffer queue;
the sending the second communication data to the mobile terminal through the communication tunnel specifically comprises:
sending the downlink MAC frame stored in the downlink buffer queue to the mobile terminal through the communication tunnel.

5. A wireless communication method, comprising:
establishing, by a mobile terminal, a communication tunnel with a Customer Premises Equipment (CPE), wherein a network identification (ID) of a wireless network sent from the mobile terminal is used to determine that the mobile terminal and the CPE are located in the wireless network;
sending, by the mobile terminal, a first request message to the CPE, wherein the first request message comprises air interface connection information between the mobile terminal and a base station (BS) where the CPE is attached;
sending, by the mobile terminal, first communication data to the CPE through the communication tunnel, so that the CPE sends the first communication data to the BS through the air interface connection information in the first request message; and
receiving, by the mobile terminal, second communication data sent by the CPE through the communication tunnel, wherein the second communication data is data received by the CPE from the BS according to the air interface connection information in the first request message, and
wherein before the establishing, by the mobile terminal, the communication tunnel with the CPE, the method further comprises:
receiving, by the mobile terminal, an information frame carrying wireless network information sent by the CPE, wherein the wireless network information comprises an ID of the wireless network and an ID of the BS of the wireless network where the CPE is attached; and
determining, by the mobile terminal, that the BS where the mobile terminal is attached is the same as the BS where the CPE is attached according to the ID of the wireless network and the ID of the BS of the wireless network where the CPE is attached.

6. The method according to claim 5 , wherein before the establishing, by the mobile terminal, the communication tunnel with the CPE, the method further comprises:
receiving, by the mobile terminal, an information frame carrying wireless network information sent by
