[0068] The first embodiment: a method for a dual-mode terminal to implement prepaid services in a DO and CDMA 1x hybrid network.

[0069] A dual-mode mobile phone has NAI, 1x IMSI, and 1x MDN in a CDMA 1x network, and only NAI in a DO network. In general scenarios, the NAI in a CDMA 1x network is the same as that in a DO network.

[0070] image 3 It is a schematic diagram of networking for the dual-mode terminal described in the first embodiment to realize the prepaid service in the DO and CDMA 1x hybrid network. see image 3 , the network mainly includes DO access network equipment, core network equipment, intelligent network SCP and OSS, of which DO access network equipment mainly includes AN and ANAAA servers; core network equipment mainly includes PDSN / PPC and AAA / PPS.

[0071] From the perspective of business operation, the general packet domain core network and the circuit domain share intelligent network equipment, prepaid user data and voice accounts are the same, a...

[0085] The second embodiment: a method for a dual-mode terminal to implement a prepaid service in a pure DO network.

[0086] Figure 4 It is a schematic diagram of the networking of the dual-mode terminal in the second embodiment to realize the prepaid service in the pure DO network. see Figure 4 :

[0087] When a prepaid terminal user registers a prepaid service, since the dual-mode terminal does not have an MDN in DO mode, the dual-mode terminal is first assigned a unique 1x IMSI in ANAAA through NAI and mapped as an MDN. According to the specific operation strategy, if the DO network still uses the 1x prepaid card, the MDN is the 1x MDN of the prepaid mobile terminal in the CDMA 1x network; if the DO network dedicated prepaid card is issued, the MDN is A virtual MDN generated from this IMSI. The virtual MDN does not occupy real number resources, and it can be generated in a variety of ways, for example, it can be generated by adding a construction prefix to the last 8...

[0092] Embodiment 3: A method for a single-mode DO AT to implement a prepaid service in a DO network.

[0093] Figure 5 It is a schematic diagram of the networking of the single-mode DO AT implementing the prepaid service in the DO network described in the third embodiment. see Figure 5 :

[0094] When a prepaid AT user registers a prepaid service, since the single-mode DO AT does not have an MDN and a fixed IMSI in the DO network, the unique NAI of the single-mode AT is mapped to a unique fixed IMSI and a unique MDN, the MDN is a virtual MDN. The virtual MDN can be generated by adding a prefix to the last 8 digits of the IMSI. The prefix includes: network code, country code, mobile subscriber identification number (MSIN) number segment, and the MSIN number segment can be Fill in the number segment that does not exist at present to identify the virtual MDN dedicated to EVDO. Then, the OSS is set to store the NAI of the prepaid AT, and the binding relationship correspondi...

Abstract

The invention is suitable to DO access network of packet data in high speed. The system sets up binding relation among prepaid mobile terminal NAI, IMSI, MDN in OSS, and adds new interface between ANAAA and OSS of DO access network. Through the said new interface, the method sends down binding relation to ANAAA; and through the current interface, sends down binding relation to AAA in core network. The method includes steps: when comm. service is carried among prepaid mobile terminals, ANAAA assigns IMSI of binding to corresponding NAI of prepaid mobile terminal as mobile terminal id in network to the prepaid mobile terminal; based on IMSI, AAA server sends MDN being looked up corresponding binding as prepaid mobile terminal id to SCP for carrying out account maintenance process of prepaid service; based on allotted money, the prepaid mobile terminal carries out comm. service. The invention realizes prepaid service under DO network accorded with intelligent network.

Description

technical field [0001] The invention relates to a method for realizing prepaid service in a communication network, in particular to a method and a system for realizing prepaid service in cooperation with an intelligent network in a code division multiple access (CDMA) 1x network and a high-speed packet data network (EVDO) network. Background technique [0002] Among the services provided by the current communication system, there is a prepaid service. The prepaid service is a service in which the user pre-purchases a certain amount of service. For example, in the data prepaid service, the service is reflected in a certain amount of usage time or data traffic. In this prepaid service, the prepaid network element device tracks the user's usage of purchased resources in real time, such as time or traffic usage, and deducts the current usage fee from the user's account balance in real time according to the current usage. [0003] The current prepaid service is mainly provided t...
