Embodiment

[0072] At present, the Mobile Virtual Network Operators (MVNO, Mobile Virtual Network Operators) service cooperated by ZTE Corporation and China Telecom North America Branch (CTA, China Telecom of America) is a one-card multi-number user terminal service. You need to use a one-card multi-number user terminal and a SIM card to solve the problem of double-number automatic roaming between China and the United States through one card with two numbers; China Telecom CDMA users, if they need to go to the United States, Go to the business hall to open the MVNO service 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 between China and the United States, you can freely choose which network to use when you turn it on, and you can call with the IMSI number of any country, and other people can call any n...

Abstract

The embodiment of the invention discloses a method for realizing intelligent roaming services. The method comprises the following steps that: when a user terminal with one card and multiple numbers is started up in the first country and selects first numbers, a home location register (HLR) in the first country sends phone activation (HAT) information to a service control point (SCP); and, when the user terminal with one card and multiple numbers roams to other countries and a common user terminal in the first country calls the user terminal with one card and multiple numbers through the first numbers in the first country, the SCP converts the first number into numbers corresponding to the country to which the user terminal with one card and multiple numbers roams according to the phone activation (HAT) information. The invention further provides a system for realizing intelligent roaming services. According to the technical scheme disclosed by the invention, the higher international roaming problem of the user terminal with one card and multiple numbers 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...
