Embodiment 1

[0051] Example 1: The source BSC version is higher than the target BSC

[0052] See attached figure 2 , where the version of the source BSC is relatively high, and when the A17 interface is incompatible, the steps for switching from the source BSC to the target BSC include:

[0053] The source BSC sends a specific A17 message to the target BSC. This specific A17 message is the first A17 message sent by the source BSC to the target BSC during the A17 handover process, which includes the version number of the source BSC. In all versions of the access network This message has a fixed structure.

[0054] After the target BSC receives the specific A17 message, it extracts the version number identifier of the source BSC from the message and saves it, and then returns a specific response message to the source BSC (this response message carries the version number of the target BSC, and the version number of the source BSC is different in different versions) Incoming network also ha...

Embodiment 2

[0059] Example 2: The target BSC version is higher than the source BSC

[0060] as attached image 3 As shown, where the version of the target BSC is relatively high, when the A17 interface is incompatible, the steps to realize the handover from the source BSC to the target BSC include:

[0061] The source BSC sends a specific A17 message to the target BSC (this message is the first A17 message sent by the source BSC to the target BSC during the handover process, including the version number of the source BSC, and this message has a fixed structure in all versions ). After the target BSC receives it, it extracts the version number identifier of the source BSC from the message and saves it, and then returns a specific response message to the source BSC (this response message carries the version number of the target BSC, and has the same structure in different versions) , the source BSC acquires the version number of the target BSC through the A17 response message returned fro...

Abstract

The invention discloses a code division multiple access (CDMA) system and an A17 interface compatibility realization method, belonging to the mobile communication technology field. The method comprises the following steps: in the CDMA system, a corresponding relation between a version number and an interface structure in an access network is configured; when A17 interface switching happens, a source access network and an object access network acquire version information of an opposite side respectively through message interaction; according to the corresponding relation between the version number and the interface structure, the source access network and / or an object access network compare / compares a self version with a version of the opposite side, if versions are inconsistent, one side of a higher version converts a sent A17 message into a format of a lower version to carry out sending, and converts an A17 message received by an access network of the lower version into the self version to carry out processing. According to the system and the method in the invention, an incompatible problem between different A17 interfaces in A17 switching between different access networks in the CDMA system is solved, and switching failure caused by incompatibility is avoided.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a code division multiple access system and an A17 interface compatible implementation method thereof. Background technique [0002] The application of the current communication system is becoming more and more extensive, and the requirements for the service quality of the communication network are also getting higher and higher. As important indicators of network quality, handover success rate and call drop rate of the communication system are getting more and more attention. CDMA (Code Division Multiple Access, Code Division Multiple Access) wireless communication system is widely used today as a communication system, and its handover success rate is also valued by people. [0003] The A17 interface is an interface used by the CDMA system during inter-BSC (Base Station Controller, base station controller) handover. It is mainly used for information exchange between...
