Hi,user7777777.

IP BSS is a radio transmission solution with which the signaling and traffic signals on the A, Abis, Gb, and Ater interfaces are transmitted by using IP technology.

IP BSS has the following advantages:

l The major advantages of IP transmission are high bandwidth and low cost, thus making it easy for telecom operators to introduce new services as required.

l IP transmission caters to the requirements of high-bandwidth data services and keeps pace with the evolution to fixed-mobile convergence (FMC) and all-IP, thus reducing the cost of network evolution.

l Both the transport network and the operation and maintenance (OM) network of signaling and traffic signals adopt IP transmission. Thus, the network OM cost is reduced.

l The packet switching technique of the IP network is used to multiplex transmission resources. Compared with TDM transmission, IP transmission utilizes the transmission resources more effectively and helps reduce the capital expenditure (CAPEX) and operating expense (OPEX) of the bearer network.

l After IP transmission is applied on the interfaces, resource pool can be implemented in the MSC, SGSN, and BSC, thus improving the network reliability and enhancing the telecom operator's brand recognition. The network element (NE) resources in the pool are shared. This increases the NE usage, reduces the telecom operator's investment in the MSC, SGSN, and BSC, and facilitates the configuration and OM.

l  

l IP BSS keeps pace with the trend towards common transmission and bearer of the 2G and 3G networks.

The extensive use of IP technology has made the IP equipment affordable and the IP bandwidth easily accessible. The implementation of IP BSS maintains pace with the trend towards flat network, thus reducing the network construction cost and facilitating the network maintenance. Figure 2-1 shows the network topology of IP BSS.

According to the interface, IP BSS is classified into the following:

l A over IP

In A over IP mode, signaling and speech signals are transmitted over the A interface by using the IP technology. On the A interface, the signaling plane uses the SCCP/M3UA/SCTP/IP protocol stack and the user plane uses the RTP/UDP/IP protocol stack for transmission. The function of transcoding from TRAU to PCM is taken over by the MGW from the TCS.

l Abis over IP

In Abis over IP mode, signaling and speech signals are transmitted over the Abis interface by using the IP technology. On the Abis interface, the signaling plane uses the LAPD over UDP/IP protocol stack and the user plane uses the PTRAU over UDP/IP protocol stack for transmission.

l Gb over IP

In Gb over IP mode, signaling and PS signals are transmitted over the Gb interface by using IP technology. The BSSGP/NS/UDP/IP protocol stack is used on the Gb interface for transmission.

l Ater over IP

In Ater over IP mode, speech signals are transmitted over the Ater interface by using the IP technology. On the Ater interface, the user plane uses IP over PPP for transmission, and the signaling plane uses the traditional TDM mode for transmission.

According to the network planning, different network topologies are applied on the interfaces to meet the actual requirements. The active/standby, load sharing, and link detection mechanisms are adopted to ensure the networking reliability. In addition, various QoS mechanisms are employed to achieve high QoS in IP transmission.
