Description

TECHNICAL FIELD The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for identifying an international roaming type of a code division multiple access (CDMA) network. BACKGROUND OF THE INVENTION With the continuous development of society, more and more people have the opportunity to go abroad. In order to provide better communication services for the personnel of the country, operators have successively launched a card double-numbered and landing roaming service to meet the requirements of different personnel. One "^ double-number service uses one User Identity Module (UIM) card for the user, corresponding to two mobile phone numbers, one is called the primary number, the other is called the secondary number, and the primary number is the primary carrier. Provided, the secondary number is provided by the partner operator. The one-card dual-number product increases the frequency of the user's use of the telecommunication service by increasing the convenience of communication, and can increase the business income by collecting the service function fee. It means that users who have not opened the international roaming right can open the regional roaming right of the attribution and roaming places and the regional long-distance rights of the two places in the roaming place, and can continue to use the voice and short message service. The scope of domestic network coverage is equivalent to extending the coverage of domestic mobile networks to overseas. The service routing of the existing international roaming value-added services is shown in Figure 1, at the Advanced Signal Transfer Point (HSTP). ) and International Signal Transfer Point (Intelligent Signal Transfer Point, referred to as The network of the international roaming value-added service platform is added between the ISTPs. The service logic of one-card double-numbered and floor-standing roaming is provided, and the corresponding user service data is stored to implement the roaming service function. The user crosses the mobile switching center (Mobile Switching Center, referred to as MSC). /visit location register

(Visited Location Register, referred to as VLR) When moving, the registration notification process will be triggered as shown in Figure 2. The specific service routing is as follows. All registration notification requests are sent to the international roaming value-added service platform. The service platform judges the roaming service opened by the user according to the number and user service data. If the matching, the source address is modified to the platform global addressing code (Global Title, Referred to as GT). After receiving the Home Location Register (HLR), the registration notification response is triggered. If the non-roaming service is used, the route does not pass through the service platform. For example, if the roaming service is used, the service platform performs number conversion and rights allocation processing. However, the inventors have found in the practice of the present invention that only the user and the current location are distinguished in the conventional scheme, and the roaming type of the user cannot be distinguished.
