A method and system for implementing short distance wireless communication in public switched telephone network

Abstract

The invention discloses a method and system for realizing short distance wireless communication in public telephone exchanging network, which is used between the public telephone exchanging network and wireless mobile communication network, through connecting a PSTN wireless accessing unit on the public telephone switching network, and arranging a double-model wireless terminal which can be used in wireless mobile communication network; the double-model wireless terminal is transplanted to the PSTN wireless accessing unit range, and creates wireless communication channel with the double-model wireless terminal through the PSTN wireless accessing unit, the double-model wireless terminal can register can connect to the PSTN wireless accessing unit automatically or manually, and accesses in the public telephone switching network. The method and system use the current public telephone switching network resources fully, provides convenient voice and data service to user with low cost.

Description

technical field [0001] The present invention relates to a communication method and system using public telephone network and wireless communication network, in particular to a method for realizing voice and data wireless communication in public telephone switching network and a system for realizing the method. Background technique [0002] At present, there are about 280 million business trips in the world every year, 20% of which require the support of the Internet or the internal network of enterprises, which opens up a huge application field for wireless access technology. For mobile users, the services they need are divided into two categories, voice services and data services. Existing communication systems provide different solutions for different applications. [0003] At present, wireless communication systems such as GSM and CDMA mainly provide voice services to mobile phone users. With the evolution of GSM networks and CDMA to 2.5G and 3G, the proportion of data s...

[0004] Although the call cost of the PHS system is relatively low, for operators, the establishment of a PHS network also means a huge investment in system equipment. Coverage is far less than GSM and CDMA networks

If a user wants to use a PHS mobile phone locally and use a GSM or CDMA mobile phone while on a business trip, he must purchase two mobile phones separately, which increases the cost of use for the user and also causes inconvenience to carry.

The wireless local area network represented by the 802.11x standard (IEEE wireless local area network standard) and the HiperLAN / 2 standard (the wireless local area network standard being developed by ETSI) has also made great progress in recent years, but it mainly provides data services, although it can be equipped with The mobile office users of notebook computers with wireless LAN cards provide greater convenience, but it is difficult to cooperate with wireless mobile communication terminals such as mobile phones
