Embodiment Construction

[0045] The embodiment of the present invention provides a method and system for transmitting 2G services through a 3G network. The main technical features of the method are: the transmission from the BSC to the BTS is forwarded by the RNC and the NODEB, and the BSC and the NODEB complete the function of time slot crossover. Between RNC and NodeB, 2G and 3G services are simultaneously transmitted through the IP transmission network.

[0046] The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. The schematic diagram of the embodiment of the method of the present invention is shown in Figure 2, and the processing flow of the embodiment of the method is shown in Figure 3, including the following steps:

[0047]Step 3-1: BSC sends the 2G service that needs to be sent to BTS to RNC.

[0048] E1 is the rate standard of the primary group of the pulse code modulation multiplexing system digital system in Europe. It includes...

Abstract

This invention provides one method and system to transmit 2G business through 3G network, which comprises the following steps: adopting IP transmission type base station controller RNC and NodeB through IP transmission network and sending 3G business and base station controller BSC and base station BTS 2G business. The system comprises BSC, RNC, NODEB and BTS.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and system for transmitting 2G services through a 3G network. Background technique [0002] In the R99 protocol of WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access), the interface IUB interface between the NODEB (base station) and RNC (base station controller) of WCDMA adopts ATM (asynchronous transfer mode, asynchronous transfer mode) Mode) transmission protocol, with the development of IP technology. In the REL5 protocol, the network diagram of the IUB interface is shown in Figure 1, and the IUB interface is connected in an IP mode. There will be a transmission network in the middle. The current mainstream transmission physical layer is E1 / T1, so in the REL5 protocol, IP is carried on E1 / T1, which is called IPover E1 / T1 (IP is carried on the entire E1 / T1) and IP over Fractional E1 / T1 T1 (IP is carried on some E1 / T1). [0003...
