Example Embodiment

[0053] 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] Step A, the AGW that manages the indoor station, the AGW that manages the macro station, and the macro station are all in a normal operating state.

[0056] Step B: The Repeater is powered on, and the CPE therein automatically connects to the macro base station in a WiMAX terminal mode to establish a two-way 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 that manages the macro 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 over-the-air signaling, processes it and generates an AGW R6 control message sent to the management indoor station, and sends the R6 control message to the Repea...

Example Embodiment

[0069] Example 2

[0070] This example is a communication processing method for downlink service data based on the present invention, which mainly includes the following processing:

[0071] 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: The AGW that manages the indoor base station classifies the above media messages, encapsulates them into GRE messages and maps them to the corresponding R6 tunnel. The destination IP address of the GRE message is the IP address of the indoor coverage station, and the network addresses it to Manage the AGW of the macro station.

[0073] Step C: The AGW managing the macro station classifies and maps the message 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] Step D: The macro base statio...

Example Embodiment

[0077] Example 3

[0078] This example is a communication processing method for uplink service data based on the present invention, which mainly includes 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, and generates R6 media messages sent to the AGW of the management indoor station after the treatment. The indoor base station sends the R6 media messages to the Repeater via the power line, and the Repeater processes the media messages. On the classified air connection, the media message after data processing is sent to the macro base station.

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

[0082] Step D: After the AGW of the management macro station is decapsulated by the GRE, the da...

Abstract

The invention discloses a data transmission method and a data transmission system. The data transmission system comprises a macro base station, an indoor base station, a repeater, a first gateway for managing the macro base station, and a second gateway for managing the indoor base station, wherein, the indoor base station is electrically connected with the repeater for realizing data interaction with the repeater and a terminal belonging to the indoor base station; the repeater is used for realizing data interaction with the macro base station; the macro base station is used for realizing data interaction with the first gateway; and the second gateway is used for realizing data interaction with the first gateway. 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...
