Short message communication system and terminal apparatus for fixed network

Abstract

The invention provides a network side system for fixed network short message communication, the subsystem comprises: an access network end separator used for multiplexing and de-multiplexing signals, a broadband access server used for realizing the access of users, a short message center used for processing and managing the short message service, a service server used for providing data and value added services related to the short message. By adopting of the invention, the network side systems can share the broadband access server and only a plurality of communication protocols need to be added according to requirements; an FSK access server and a CTSI server added separately for the short message service in the existing fixed network short message method are not needed, therefore, the realization of the technique is simpler; meanwhile, the network utilization rate is increased and the service is enriched; the operator can tightly combine the fixed network short message service with the broadband data service.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fixed communication network system and a terminal with short message and broadband access functions. Background technique [0002] With the rapid development of mobile communication technology, the scale of mobile communication network continues to expand, and new services continue to emerge, which has formed an alternative competition with fixed telecommunication networks. In 2003, the number of mobile subscribers in China began to surpass that of fixed-line subscribers, and the gap between the two has been widening in recent years. According to statistics from the Ministry of Information Industry in May 2007, China's telephone users reached 850 million, of which fixed-line users reached 371 million, including nearly 100 million PHS wireless local phone users. The fixed-line penetration rate was 28.1%, with a monthly increase of about The number of mobile users reached ...

AI Technical Summary

Problems solved by technology

[0005] (2) The fixed telecommunication network is mainly based on the voice service, and the value-added service is also mainly based on the voice service, and the service is relatively scarce; while the broadband data service is limited by the popularity of computers

[0011] (1) The existing fixed-line SMS is realized as a specific service, and a specific modulation and demodulation method is required to transmit SMS data on the subscriber line. The whole solution ignores the data service characteristics of SMS and lacks flexibility. and scalability

[0012] (2) The implementation method of the existing fixed-line short message is based on the transmission of the voice channel, and a voice channel needs to be established between the user terminal and the fixed-line short message platform, so a phone call cannot be made when sending a short message; and when the called user is busy, the fixed network The download initiated by the SMS platform will fail. Although there is a retry mechanism, setting the number of retries and frequency too high will reduce the efficiency of the entire system

[0013] (3) The transmission rate of the existing fixed-line SMS is low, the sending time is long, the number of words is small, and the scalability of terminals and services is poor

[0016] (6) Customers such as ISDN (Integrated Service Digital Network), ADSL (Asymmetric Digital Subscriber Line) and small switches cannot use the fixed-line SMS service for the time being

[0017] (7) In the near future, optical fiber access methods such as FTTB and FTTH will be commercialized on a large scale, and all-optical access or hybrid optical access will become the mainstream, and the existing fixed-line SMS methods will no longer be applicable
