Description

Mobile terminal communication method and device

technical field

The present invention relates to the communication field, in particular to a mobile terminal communication method and device.

Background technique

PBX (Private Branch eXchange, Private Branch Exchange), in short, is a group phone, it occupies an important position in the original telecommunications communication architecture, even today, it is still a common communication method for many enterprises. With the emergence of new technologies, people's needs are changing with each passing day, and the shortcomings of the traditional PBX are slowly exposed. First, it does not support the emerging CTI (Computer Telephony Integration, the integration of computers and telephones) and Voip (Voice over Internet Protocol). , At the same time, because the PBX adopts proprietary technology, it lacks standardization and openness.

Based on the above defects of PBX, IP-PBX (Internet Protocol-Private Branch Exchange, network dedicated exchange) came into being. IP-PBX telephone exchange system can realize the function integration of computer network and telephone exchange. Each telephone terminal in the IP-PBX network performs data communication in the form of IP, which can not only conduct calls, but also realize the transmission of text, data and images, unify the telephone network and computer network into a whole, and realize electronic office in the local area network.

UAP (UMTS Access Point, UMTS Access Point) is a brand new UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) wireless access point product. It provides users with standard UMTS services, and is connected to network-side devices through DSL (Digital Subscriber Line, Digital Subscriber Line))/IP broadband. UAP can provide operators with a low-cost home/SOHO (Single Office Home Office) indoor coverage solution, which can improve network coverage and capacity through user deployment, especially in the current surge of data services , as an effective carrier of mobile broadband, UAP can absorb a large amount of data services without any impact on the original network, but users can enjoy the low tariff of Home Zone and home network applications.

According to the networking structure of UAP, if a mobile terminal residing in a FemtoCell (femtocell base station) wants to access the external Internet (Internet) network, it needs to activate PDP (Package Data Protocol, packet data protocol) first. After the PDP activation is successful, the ordinary data flow passes through UE (User Terminal Equipment), AP (Access Point, Access Point), HGW, SGSN (Service GPRSSupport Node, Service GPRS (General Packet Radio Service, General Packet Radio Service) in the uplink direction Wireless service) support node), GGSN (Gateway GPRS Support Node, gateway GPRS support node) to the Internet (or Intranet); ordinary data flow passes through the Internet (Intranet), GGSN, SGSN, HGW, AP, and UE in the downlink direction.

When the inventor realizes the communication of the above-mentioned mobile terminal, he finds that there are at least the following problems in the prior art: the mobile terminal residing under the FemtoCell cannot perform data communication in IP mode as an ordinary user in the IP-PBX network, resulting in When the mobile terminal staying under the FemtoCell communicates with the users in the IP-PBX network, certain fees will be incurred.
