Embodiment

[0072] At present, the Mobile Virtual Network Operators (MVNO, Mobile Virtual Network Operators) service cooperated by ZTE and China Telecom North America Branch (CTA, China Telecom of America) is a one-card multi-number user terminal service. Users only need to Using a multi-number user terminal with one card and one SIM card, you can solve the problem of automatic roaming with double numbers between China and the United States by means of one card with two numbers; if China Telecom CDMA users need to go to the United States, they can Open the MVNO service in the business hall and apply for a SIM card. This card has two IMSI numbers, one is a Chinese number and the other is an American number. The Chinese number is provided by China Telecom, and the American number is provided by the US Sprint Company. Roaming with the United States, you can freely choose which network to use when you turn it on, you can call with the IMSI number of any country, and other people can call any n...

Abstract

The embodiment of the present invention discloses a method for implementing an intelligent roaming service, including: when a one-card-multi-number user terminal is powered on in a first country and selects a first number, the home location register (HLR) of the first country sends a mobile phone activation (HAT ) message to the service control point (SCP); when the one-card multi-number user terminal roams to other countries, and the ordinary user terminal in the first country calls the first number of the one-card multi-number user terminal in the first country, the SCP activates the (HAT) message, and convert the first number into a number corresponding to the country to which the one-card multi-number user terminal roams; the present invention also provides a system for realizing an intelligent roaming service. According to the technical scheme of the invention, the problem of high international roaming charges of the one-card-multi-number user terminal is solved.

Description

technical field [0001] The embodiment of the present invention relates to the field of mobile communication, and in particular to a method and system for realizing an intelligent roaming service. Background technique [0002] With the continuous development of telecommunications services in domestic and overseas markets, more and more people often travel between the two countries, and the demand for international roaming services is also increasing, but the high international roaming charges also increase the user's communication costs . On the other hand, when the one-card-multiple-number user terminal is roaming internationally, the mobile switching center (MSC, Mobile Switching Center) in the roaming place asks the home location register (HLR, Home Location Register) for the user subscription information of the smart roaming service, Some HLRs usually suppress the roaming of foreign smart users, that is, when a one-card multi-number user terminal performs international r...
