Description

Mobile terminal communication method and device

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

Background technique

PBX (Private Branch eXchange), in short, is the PBX, which occupies an important position in the original telecommunications communication architecture. Even today, he is still the common communication method for many enterprises. With the advent of new technologies, people's needs are changing with each passing day, and the shortcomings of traditional embarrassment are slowly exposed. First, it supports the emerging CTI (Computer Telephony Integration) and Voip (Voice over Internet Protocol). Not enough, and because the PBX uses proprietary technology, it lacks standard and openness.

Based on the above defects of PBX, IP-PBX (Internet Protocol-Private Branch exchange) came into being. The IP-PBX telephone exchange system enables the functional integration of computer networks and telephone switches. Each telephone terminal in the IP-PBX network performs data communication by IP, which can not only carry out calls, but also realize transmission of text, data and images, and unify the telephone network and the computer network into one 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) wireless access point product. It provides users with standard UMTS services and connects to DSL (Digital Subscriber Line) / IP broadband and network side devices. UAP can provide operators with a low-cost home/S0H0 (Single Office Home Office) indoor coverage solution that can increase 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 number of data services without any impact on the original network, but users can enjoy low rates of Home Zone and home network applications.

According to the UAP networking structure, a mobile terminal residing under the FemtoCell (femtocell base station) needs to access the external Internet (interconnect) network, and needs to do PDP first (Package Data). Protocol, Packet Data Protocol) is activated. After the PDP is successfully activated, the normal data stream passes through the UE (User Terminal Equipment), AP (Aces s Point, Access Point), and HGW in the uplink direction.

SGSN (Service GPRS Support Node, Service GPRS (Generation Packet Radio Service) support node), GGSN (Gateway GPRS Support Node), to the Internet (or Intranet); common data stream in the downstream direction Pass through

Internet (Intranet), GGSN, SGSN, HGW, AP, UE.

When the inventor realizes the communication of the mobile terminal, it is found that at least the following problems exist in the prior art: The mobile terminal residing under the FemtoCel l cannot perform data communication in an IP manner as an ordinary user in the IP-PBX network, resulting in Mobile terminals residing under FemtoCel l will incur a fee when communicating with users on the IP-PBX network.
