Embodiment 1

[0054] Figure 4 ~ Figure 7 Shown is one of the embodiments of the invention. In this embodiment, a mobile communication network service access system, such as Figure 4 As shown, it includes a client 101 , a service support node SGSN and a gateway support node GGSN 108 . The service support node SGSN is provided with a virtual private network VPN service access function to form a VPN-SGSN network element 107 .

[0055] VPN-SGSN network element 107 includes the following subunits:

[0056] The VPN service subunit 102 is used to perform the VPN access service function, accept the VPN access request initiated by the client, and receive and forward the client's uplink and downlink business data;

[0057] The signaling intercommunication subunit 103 is used to perform conversion between VPN signaling and GMM / SM protocol signaling;

[0058] The service access management subunit 104 is used to manage client service access and preset service access parameters;

[0059] The GTP p...

Embodiment 2

[0078] Figure 8 ~ Figure 11 Shown is the second embodiment of the present invention. In this embodiment, a mobile communication network service access system, such as Figure 8 As shown, it includes a client 101, a packet control unit PCU / radio network controller RNC, and a serving support node SGSN 112. The packet control unit PCU / radio network controller RNC is provided with a virtual private network VPN service access function to form a VPN-PCU / RNC network element 111 .

[0079] The VPN-PCU / RNC network element includes the following subunits:

[0080] The VPN service subunit 102 is used to perform the VPN access service function, accept the VPN access request initiated by the client, and receive and forward the client's uplink and downlink business data;

[0081] The signaling intercommunication subunit 103 is used to perform conversion between VPN signaling and GMM / SM protocol signaling;

[0082] The service access management subunit 104 is used to manage client servi...

Abstract

The invention discloses a service access system of a mobile communication network. Through a service function of accessing a service supporting node (SGSN) or a packet control unit (PCU) / a radio network controller (RNC) into a virtual private network (VPN), the mobile communication network is enabled to support a fixed access mode. The invention further discloses a service access method of the mobile communication network. The invention expands the service access mode of the mobile communication network so that a terminal can continue to use mobile application services under a mobile network environment through a fixed IP (Internet Protocol) access mode.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a mobile communication network service access system and method. Background technique [0002] The mobile communication network generally includes two parts, the wireless access network and the core network. The wireless access network accesses the core network through the GPRS service support node SGSN, and then the SGSN continues to connect with the GPRS gateway support node GGSN through the GTP protocol, and the mobile terminal is realized through the GGSN. Access to external data networks, such as communication systems such as GPRS, WCDMA and CDMA 2000. [0003] Take GPRS as an example, such as figure 1 As shown, the serving support node SGSN and the gateway support node GGSN are the key equipment of the core network of the GPRS / 3G communication system, and the packet control unit PCU / radio network controller RNC is the key equipment of the radio access network...
