EIP Solution for Telecom Value-Added Services

System Introduction

With the popularization of basic telecom services, telecom services have already shifted from traditional voice service to the dominant digital data service and other diversified services. Telecom value-added services include CRBT (Coloring Ring Back Tone), MMS (Multimedia Messaging Service), BGM (Background Music Service), Mobile QQ and so on. Other emerging value-added services also emerge one after another and are becoming increasingly popular. The number of telecom value-added service subscribers has seen rapid growth in recent years.

CRBT, short for Coloring Ring Back Tone, is the special sound (music, song, story, dialogue) ringtone set by the caller for other callers during calls. The caller will hear a personalized sound clip instead of repeated sound of toot, toot.

MMS, the acronym of Multimedia Messaging Service, is based on WAP (Wireless Application Protocol), transmitting text, image, voice, data and other multimedia information via GSM data network of China Mobile.

BGM (Background Music Service) is a personalized voice valued-added service customized by the caller, enabling personalized music of the caller to be heard during a call. Meanwhile, the caller can also change the background music or corresponding sound clips from time to time as required to make the conversation dynamic.

"Mobile QQ" service is a service based on the interconnection of the GSM, SMS and WAP systems of China Mobile and the QQ system of Tencent Inc., enabling mobile phone users to directly communicate with online QQ users via SMS.

Application of CPCI in Telecom Value-Added Services

Currently, the application of CPCI in telecom mainly concentrates on the telecom value-added services. CompactPCI has the open standard, high reliability and hot swap features, guaranteeing 99.999% high reliability of the telecom industry and greatly reducing the development costs of hardware and software. In terms of market price, the entire cost of CompactPCI equipment is much cheaper than the traditional telecom equipment. So, CompactPCI computing hardware platform is an effective solution for telecom operators to lower cost and adjust charges.

EVOC CompactPCI computing hardware platform is the right solution for telecom value-added services after meeting all its requirements. Below is the block diagram:

System Evaluation

The network security of platform guarantees reliable service and keeps it from external attack. The software and hardware of the system adopts distributed structure with favorable fault-tolerance. Network data, service logic and user data are independent of one another, which guarantees the conformability and reliability of data access and can withstand instantaneous high traffic load. To avoid service failure caused by single point fault, all the system modules are of N+1 configuration. Therefore, even if database server stops and switching point hangs, the system still can maintain basic telephone service.
