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 hierarchy. RECs, REs and switching networks 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 RE, and the RECs communicate with each other through the switching network. It is understandable that, if necessary, the REs can also directly communicate with each other through the switching network.

[0027] The number of RECs and REs can be multiple, and multiple RECs can be centrally placed in geographically close places, or multiple RECs can be dispersedly 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 Control) layer or IP (Internet...

Embodiment 2

[0053] In the embodiment of the present invention, the REC, RE, and the switching network are connected to each other through optical fiber, one REC manages at least one RE, and one RE belongs to one REC management, and the REC and the RE, and the RECs in pairs communicate with each other through the switching network. Between communication.

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

[0055] The RE needs to register with the REC. 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 that carries a message type field, and the message type field includes the RE's identifier, MAC address, and...

Embodiment 3

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

[0091] This embodiment provides a schematic diagram of the flow of REC transferring data to RE0, such as Picture 11 As shown, the specific processing process is as follows:

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

[0093] The MAC layer of REC composes a MAC frame based on the MAC address and data content of RE0. The structure of the MAC frame is shown in Table 5 bel...

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 field of wireless communication technology, 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 Telecommunication System) network that combines the core network and the wireless access network is as follows: figure 1 Shown. The first layer is CN (Core Network), whose main function is 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 an external network. The second layer is RNC (Radio Network Controller), whose main function is to provide mobility management, call processing, link management and handover mechanisms. The third layer is REC (Radio Equipment Control, wireless equipment control), the main function is the control and management of the base station, Iub interface communication, Iub frame p...
