Problems solved by technology

The shortcoming of described WAP access enterprise network one is that can only realize simple business, send and receive mail as WAP, visit Notes, can't realize the business such as mobile Intranet, mobile Extranet, can not fully satisfy the demand of mobile enterprise access business; The 2nd, WAP Access service operators cannot provide value-added services, and operators can only obtain data transmission fees; third, enterprises need to build and maintain WAP servers, need to develop specific application systems, and need to develop interface systems between WAP Server and Mail Server/Notes Wait, the cost is higher
The disadvantage of this method is that the enterprise needs to build and maintain its own access server, and the second is that the terminal equipment needs to support the PPP protocol function.
The main disadvantage of

Embodiment Construction

[0068] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0069] The virtual GGSN usually implements the simulation of the GGSN on the basis of the software and hardware of a large-capacity GGSN, and each virtual GGSN has an independent user plane and control plane. Virtual GGSN is functionally the same as a physically independent GGSN, and has independent Gc interface signaling software instance, GTP-C processing software instance, GTP-U processing software instance, IP protocol stack, IP packet forwarding engine, management Software instance, firewall software instance, tunnel encapsulation software instance, etc. have independent memory space, CPU resources, forwarding table, routing table, virtual port (physical interface or VPN) on the hardware. For the convenience of description, the virtual GGSN that provides enterprise access services is V-GGSN, and the virtual GGSN that provides Internet ser...

Abstract

This invention discloses a method for realizing virtual GGSN in enterprise acc service which establishes and virtual GGSm according to the information forward by OMC safeguarding station about establishing virtual GGSM to allocate SCP service managing system and establish and allocate G: interface to finish virtual GGSN to operate on processing service acc procedure, panning processing and service releasing to realize virtual GGSN. This invention also provides GGSN realization device including V-GGSN CP module, V-GGSN UP module, 1-GGSN CP module, 1-GGSN UP module, cc engine MUX function module to finish virtual GGSN control part protocol process and customer part management so as to realize virtual GGSN.

Description

technical field [0001] The invention relates to a GGSN in a GPRS communication system, in particular to a method and a device for realizing a virtual GGSN capable of realizing enterprise access services. Background technique [0002] GGSN is an important functional entity of the GPRS network and a gateway node for interconnecting the GPRS network with the external data network. The GPRS network can realize interconnection with InterNet, IntraNet, and ExtraNet through the GGSN node, and can realize services such as mobile Internet access, mobile e-commerce, and mobile enterprise access through the GPRS network. The mobile enterprise access service is the main business of the GPRS system. It mainly solves the security problem of user access to the enterprise. Security includes data privacy, data integrity, user authentication, and user authorization. Enterprise users must be guaranteed to pass The data that GPRS / 3G accesses to the enterprise network will not be tampered with ...
