Embodiment 1

[0026] The structure of a flat wireless network communication system proposed in this embodiment is as follows: figure 2 shown in figure 2 In the wireless network communication system shown, the entire network structure simplifies the network level, REC, RE and switching network are connected to each other through optical fibers, one REC manages at least one RE, and one RE belongs to one REC. , the REC and the REs, and between two RECs communicate with each other through the switching network. It can be understood that, if necessary, two REs can also directly communicate with each other through the switching network.

[0027] The number of the RECs and REs may be multiple, and multiple RECs may be concentrated in places with similar geographical locations, or multiple RECs may be scattered and placed in geographically distant places.

[0028] The switching network may be a ring-shaped metropolitan area network composed of at least one switch based on MAC (Medium Access Con...

Embodiment 2

[0053] In the embodiment of the present invention, the REC, RE, and switching network are connected to each other through optical fibers, one REC manages at least one RE, one RE belongs to one REC, and RECs and REs and between two RECs communicate with each other through the switching network. inter-communication.

[0054] Further, the core network equipment is connected to the REC, the RE, and the switching network through optical fibers, and the core network equipment and the REC, and between the core network equipment and the REs communicate with each other through the switching network.

[0055] The RE needs to register with the REC, and the RE sends an access request carrying the MAC address of the RE to the REC through the switching network, and the REC obtains and saves the MAC address of the RE carried in the access request. The RE constructs a MAC frame carrying a message type field, the message type field includes the RE identifier, the MAC address, and the indicatio...

Embodiment 3

[0090] When REC and RE need to transmit data frames to other nodes, the above-mentioned REC and RE send the data to the switching network through the optical fiber, and the switching network then transmits the data to the core network equipment, and the core network equipment transmits the data to the destination node. After the switching network establishes a complete address table through learning, data can be directly transmitted between the REC and the RE through the switching network.

[0091] A schematic flow chart of REC transferring data to RE0 provided by this embodiment is as follows: Figure 11 As shown, the specific process is as follows:

[0092] The application layer of the REC transfers the data to the MAC layer of the REC, and the MAC layer of the REC searches the MAC address table saved by the REC to obtain the MAC address of RE0.

[0093] The MAC layer of REC forms a MAC frame according to the MAC address and data content of RE0. The structure of the MAC fr...

Abstract

An embodiment of the invention provides a radio network communication system and a data transmission method thereof. The method mainly includes: RECs (radio equipment controls), RE (radio equipment) and a switched network are interconnected through optical fiber, one REC manages at least one RE, one RE belongs to management of one REC, and the RECs and the RE, each two RECs are intercommunicated through the switched network. The problem that the existing system has multiple layers and multiple interfaces and is low in resource utilization rate is solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless network communication system and a data transmission method thereof. Background technique [0002] The structure of the existing UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) network that combines the core network and the wireless access network is as follows: figure 1 shown. The first layer is CN (CoreNetwork, core network). Its main functions are to provide user connections, manage users, and carry out user services. At the same time, it serves as a bearer network to provide an interface to the external network. The second layer is RNC (RadioNetworkController, radio network controller), the main function is to provide mobility management, call processing, link management and switching mechanism. The third layer is REC (Radio Equipment Control, wireless equipment control), the main functions are ...
