example 1

[0054] This example is a communication processing method based on the control signaling of the present invention, which mainly includes the following processing:

[0055] In step A, the AGW managing the indoor station, the AGW managing the macro station, and the macro station are all in a normal operating state.

[0056] In step B, the Repeater is powered on, and the CPE in it automatically connects to the macro base station in the form of a WiMAX terminal to establish a bidirectional service flow and connection.

[0057] In step C, an R6 tunnel for the service flow in step B is established between the macro base station and the AGW managing the macro base station.

[0058] Step D, the WiMAX terminal under the coverage of the indoor base station initiates network access.

[0059] Step E, the indoor base station receives the air signaling, generates the AGW R6 control message sent to the management indoor station after processing, and sends the R6 control message to the Repeat...

example 2

[0070] This example is based on the communication processing method of downlink business data of the present invention, mainly includes the following processing:

[0071] In step A, the network side first sends the media message to be sent to the indoor terminal to the AGW that manages the indoor base station through network addressing.

[0072] Step B, after the AGW that manages the indoor base station classifies the above media packets, encapsulates them into GRE packets and maps them to the corresponding R6 tunnel, the destination IP address of the GRE packets is the IP address of the indoor coverage station, and the network addresses it to Manage the AGW of the macro station.

[0073] In step C, the AGW managing the macro base station classifies and maps the packet to the R6 tunnel established in step C of Example 1 according to the destination IP address of the message, performs GRE encapsulation, and sends it to the macro base station.

[0074] In step D, the macro base...

example 3

[0078] This example is based on the communication processing method of uplink service data of the present invention, mainly including the following processing:

[0079] Step A, the indoor terminal sends the media data to the indoor base station through the air connection.

[0080] Step B, the indoor base station receives the media data, generates the R6 media message sent to the AGW managing the indoor station after processing, the indoor base station sends the R6 media message to the Repeater through the power line, and the Repeater performs data processing on the media message, On the classified air connection, the media message after the data processing is sent to the macro base station.

[0081] In step C, the macro base station sends the received media packet to the AGW managing the macro base station through the R6 tunnel (for example, the R6 tunnel established in step C of Example 1).

[0082] Step D, after the AGW managing the macro station decapsulates the GRE, it se...

The data transmission method and the data transmission system of the invention can effectively improve the indoor network covering effect, enhance the service quality and provide convenience for application of a user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and a data transmission system. Background technique [0002] With the rapid development of network technology, WiMAX wireless network is gradually known and accepted by more and more people, and is regarded as 4G (4th Generation, 4th generation) after 3G (3rd Generation, 3rd generation) standard. [0003] Many operators around the world are actively preparing to build WiMAX networks. For large-scale operating networks, network deployment solutions for outdoor and indoor coverage need to be considered. Due to the high frequency of WiMAX, large space and penetration loss, and WiMAX mainly provides high-speed data services and requires good air signal quality, so how to solve indoor coverage is an important issue in WiMAX network deployment. [0004] At present, in order to solve the problem that the indoor coverage effect of the WiMAX network is not g...
