Embodiment Construction

[0036] The technical solution of the present invention will be described in more detail below in conjunction with the drawings and embodiments.

[0037] In the present invention, the network composed of BBU and RRU adopts a hop-by-hop connection mode. The basic topological structure is chain, ring and tree. It can also be a hybrid structure that mixes chain and tree. Each network unit is responsible for receiving data packets. , Processing and forwarding functions.

[0038] As shown in Figure 5, it is a flowchart of a method for broadcasting in a network composed of BBU and RRU, which specifically includes the following steps:

[0039] (1) The RRU or BBU to be broadcast constructs a data packet, and fills in the broadcast flag in the packet header;

[0040] (2) The RRU scans the network interface and sends the broadcast packets to the adjacent one-hop network unit one by one, that is, to the one-hop device connected to each interface;

[0041] (3) The network unit that receives th...

Abstract

The invention discloses method for carrying out broadcasting through network composed of resource pool in baseband and radio frequency unit in remote end. The method includes steps: (1) network unit to be broadcasted constructs data packet, and broadcasting symbol is filled to head of packet; (2) scanning network interfaces, the network unit sends broadcasting packets one by one to adjacent one hop network unit; (3) receiving the said broadcasting packet, network unit forwards the broadcasting packet to adjacent one hop network unit selectively; repeating step (3) till the broadcasting packet reaches to each terminal node in network; finishing broadcasting; transmission of broadcasting packet in network does not restrict by BBU and RRU network formation, number of connections, and specific frame format in link layer. Features are: flexible network configuration, easy management, not repeating forwarding broadcasting packet in any form of network, high efficiency.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for a baseband resource pool and a remote radio frequency unit in a WCDMA (Wideband Code Division Multiple Access) system to perform data broadcasting in different networking modes. Background technique [0002] In the WCDMA system, the BBU (baseband resource pool) is responsible for providing wireless coverage of the WCDMA network, and the UE (user terminal) access and wireless are completed through the Uu (user terminal UE and the universal terrestrial radio access network URTAN interface) interface. Link transmission function; connect with RNC (radio network controller) through Iub interface (interface between BBU and RNC), report BBU measurement information, send system information broadcast provided by RNC, and execute access control issued by RNC, Mobility management, radio resource management and control commands, FP (Frame Protocol) processing, ATM (Async...
