Problems solved by technology

[0022] 1. It is necessary to configure the correspondence table between the IMSI / MSISDN number segment and the GGSN IP address / domain name of the home location on all the SGSNs in the visited location. The data configuration workload is very heavy; and once the network structure changes, or the IMSI / MSISDN number segment If there is a change, it is necessary to update the corresponding relationship tables on all SGSNs, and the workload of network maintenance is huge
[0023] 2. In the case of cross-area MNP (Mobile Number Portable) or cross-operator MNP requirements, there will be no direct correspondence between the MSISDN number segment and the area to which it belongs, and the corresponding GGSN cannot be found through the MSISDN number segment. Therefore, if the corresponding relationship between the MSISDN number segment and the GGSN is configured on the SGSN in the prior art, it cannot meet the attribution access requirements of the packet data service in the case of implementing MNP

Embodiment Construction

[0043]ENUM (Electronic NUMbering, electronic encoding) is a protocol defined by IETF's Telephone Number Mapping working group (Telephone Number Mapping working group) - RFC2916, the title of RFC2916 is "E.164 Number and Domain Name System (E.164 Number and DNS )". It defines the method to convert the E.164 number into the domain name form and put it in the database of the DNS device. E.164 numbers are important resources used in traditional telecommunication networks, and DNS equipment is an important foundation of the Internet. ENUM combines the two. Each domain name converted from the E.164 number can correspond to a series of uniform resource identifiers (Uniform Resource Identifier, URI), so that the internationally unified E.164 number becomes a network address resource that can be used in the Internet. ENUM can use the E.164 number to look up the Registrant's e-mail, IP phone number, unified message, IP fax or personal web page and other information.

Abstract

The disclosed method to access local grouping data network comprises: when the mobile terminal cruises to the target area and uses APN to initiate request on grouping business, interacting by local SGSN and ENUM DNS devices to obtain the local GGSN IP address or DN and hereby initiating business request to local GGSN for accessing local grouping data network. Besides, the terminal can also access the network when mobile number carries MNP in full network, AND the ENUM DNS device is compatible to original DNS mechanism.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for accessing a home packet data network. Background technique [0002] Mobile packet data services are widely used rapidly due to their advantages such as convenient mobility, high-speed transmission rate, and rich mobile data services, as defined in the standard protocol of 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization partner project) The GPRS (General Packet Radio Service, general packet radio service) / WCDMA (Wide (band) Code Division Multiple Access, wideband code division multiple access) system enables mobile terminals to access packet data services. In these systems, SGSN (Serving GPRS Support Node, service GPRS support node), GGSN (Gateway GPRS Support Node, gateway GPRS support node) and DNS (Domain Name System, Domain Name System) equipment in the system are connected through the Gn interface , to implemen...
