Problems solved by technology

[0003] With the continuous evolution of the protocol, the coexistence of 1x service and EV-DO service gradually appears in the market. The former is 2G data service, the latter is 3G data service, and EV-DO service is still evolving. Therefore, in the commercial environment There is a problem that the PDSN supporting 1x service and the PDSN supporting EV-DO service coexist but are not compatible. When a user initiates a call for one of the services, the PCF entity may appear because the PCF entity does not distinguish the service type in processing. When a 1x service call is connected to a PDSN that does not support the 1x service or an EV-DO service call is connected to a PDSN that does not support the EV-DO service, the PCF entity needs to reselect the PDSN, resulting in waste of resources and increase in system load

[0025] In this embodiment, the BSC that supports 1x service and EV-DO service is connected to the same PCF entity. The PCF entity supports both 1x service and EV-DO service. The PDSN connected to the PCF entity supports both 1x service and support EV-DO business, there are two kinds of business support, such as figure 1 shown. In this embodiment, the following configuration is first required: configure the service type information supported by each PDSN connected to it in the PCF entity, that is, record the service type supported by each PDSN on the PCF entity, for example, it can be configured in the form of a list .

[0026] based on figure 1 connection relationship, the method for selecting a PDSN in this embodiment includes the following steps:

[0027] Step 110, the BSC connects the user's wireless packet data service call to the PCF entity, with the service type identifier in the call;

[0028] The service type identifier can be brought to the PCF entity through the ...

[0032] In this embodiment, the PCF entity is distributed, and the BSC supporting the 1x service and the BSC supporting the EV-DO service are respectively connected to the PCF entity supporting the corresponding service type, and the PCF entity is only connected to the PDSN supporting the corresponding service type, like figure 2 shown. In this embodiment, the following configurations are first required: configure all PDSNs supporting 1x services on some PCF entities, and configure all PDSNs supporting EV-DO services on another part of PCF entities;

[0033] based on figure 2 connection relationship, the method for selecting a PDSN in this embodiment includes the following steps:

[0034] Step 210, the BSC supporting the 1x service and the BSC supporting the EV-DO service respectively send the user's wireless packet data service call to the PCF entity supporting the corresponding service type;

[0035] Step 220, after receiving the call, the PCF entity selects a PDSN from ...

Abstract

The invention provides a compatible method for accessing a wireless packet data service call with different service types. A base station controller BSC transmits a wireless packet data service call to a packet control function PCF entity, the wireless packet data service call carries service type marks, and the PCF entity transmits the wireless packet data service call to a packet data service node PDSN of the service types to treat according to the service type marks. The method enables 1x service and EV-DO service in a code division multiple access CDMA wireless network to be smoothly connected to the PDSN which can support the service and solves the problems of coexistence and incompatibility of the PDSN for supporting the 1x service and the PDSN for supporting the EV-DO service in commercial environment, and the 1x service and the EV-DO service can not be mutually influenced.

Description

technical field [0001] The invention relates to the field of CDMA (Code-Division Multiple Access, Code Division Multiple Access) mobile communication systems, in particular to a compatible method for calling and accessing wireless packet data services of different service types. Background technique [0002] In the CDMA wireless network, the PCF (Packet Control Function) entity is mainly responsible for cooperating with the BSC (Base Station Controller, base station controller) to connect packet data users to the PDSN (Packet Data Serving Node, packet data service node) superior. According to the relevant provisions of the CDMA2000 standard, the BSC is connected to the PCF entity through the A9 (control plane interface) / A8 (media plane interface) interface, and the interface between the PDSN and the PCF entity is A11 (control plane interface) / A10 (media plane interface). The user establishes a connection with the PDSN data application through the above interface, and the PC...
