Embodiment Construction

[0036] The purpose of the present invention is to provide a method for implementing user roaming restriction in 1X EV-DO system. Such as figure 1 As shown, a method for restricting roaming in a 1XEV-DO system includes the following steps:

[0037] Step 1: When the terminal accesses the network, the access network where it is currently located acquires roaming allowed area information and current location information of the terminal;

[0038] Step 2: The access network where the terminal is currently located determines whether the current location of the terminal is within the allowed roaming area, and if not, restricts the terminal to roam at the current location.

[0039] The terminal AT (Access Teminal, referred to as AT) accesses the Internet through the access network AN and the packet data service node PDSN, and performs data transmission. Due to the characteristics of moving at any time, in the process of accessing the Internet, AT may move from one area under the same...

Abstract

The invention relates to a roam limiting method of a 1X EV-DO system, including a treating process when in access, wherein the process comprises the following steps: step 1. When the terminal is accessed to the network, the current access network obtains roam allowing area information and the current position information of the terminal; step2. The access network on which the terminal is on judges whether the current position is in the roam allowing area, if true, the terminal is limited to roam at the current position. The roam limiting method of the 1X EV-DO system realizes the roam limit on the user, which is convenient for the operator to develop operations.

Description

technical field [0001] The invention relates to a method for restricting roaming in 1X EV-DO system, in particular to a method for restricting roaming in CDMA2000 1X EV-DO system. Background technique [0002] CDMA2000 Evolution-Single Data System 1X EV-DO (CDMA2000 1XEvolution-Data Only), referred to as CDMA2000 1X EV-DO. CDMA2000 1X EV-DO evolved from Qualcomm's high-speed data rate HDR (High Data Rate) system and is a member of the CDMA2000 standard family. In October 2000, the second group of the Third Generation Partnership Project 3GPP2 (Third Generation Partnership Project 2, referred to as 3GPP2) officially released the CDMA2000 1X EV-DO standard. In December 2001, the International Telecommunication Union standard ITU (International Telecommunication Union, referred to as ITU) Officially adopted a resolution to use CDMA2000 1X EV-DO as part of the IMT-2000 (International Mobile Telecommunications) series of standards. [0003] CDMA2000 1X EV-DO is a technology opt...
