Their business. In order to identify each MSC's unique position in the network, each MSC must have its own signaling point code (0PC) on the A interface side and the network side. In China's GSM standard, the A interface side uses 14 bits of signaling. The point attribute is a domestic backup signaling point code.
  • the MSC For MSC equipment that does not use the multiple signaling point technology, the MSC has only one unique signaling point code on both the A interface side and the network side. For MSC equipment using multiple signaling point technology, the MSC can virtualize multiple signaling points on the A interface side or the network side. Each signaling point is considered to be its own 0PC. For other network elements, each The signaling points still correspond to one MSC entity, and it is not known whether the physical entities corresponding to these signaling points are the same MSC.
  • the backup MSC can simulate multiple 14-bit A interface signaling points of its backed MSC and complete the A interface circuits, links, and location area cells within the jurisdiction of the simulated A interface signaling points Management, the 14-bit A interface signaling point technology needs to be used in the backup MSC to make it have multiple signaling point functions.
  • FIG. 2 The principle of the method according to the invention is referred to FIG. 2.
  • the system described in the figure has three MSCs, MSC1, MSC2, and backup MSC.
  • the BSCs connected to the above MSCs are BSC1, BSC2, and small-capacity BSC.
  • BSC1, BSC2, and small-capacity BSC To enable the backup MSC to take over its services when MSC1 and MSC2 fail, configure the following signaling point data in the backup MSC:
  • the backup MSC can simulate multiple 14-bit A interface signaling points, which respectively represent the multiple 14-bit A interface signaling points of its backup.
  • the backup MSC simulates three 14-bit A interface signaling points, where OxCl simulates the A interface signaling point of MSC1, 0xc2 simulates the A interface signaling point of MSC2, and 0xC3 is the normal operation of the backup MSC, that is, it does not take over other Signaling point of own A interface when MSC fails.
  • the backup MSC can activate the 14-bit A interface signaling point owned by the faulty MSC in the local office. As a 14-bit A interface signaling point actually operated by the local office, multiple MSCs fail. Then, corresponding multiple 14-bit A interface signaling points can be activated, so that the backup MSC can completely simulate the function of the failed MSC on the A interface side and assume the services of the failed MSC without the need for the BSC to modify the office configuration data. In this way, the backup MSC can have the correspondence between the N 14-bit A interface signaling points and the connected BSC signaling points simulated by the local office, as well as all the backup location information of multiple MSCs.

  • the signaling point configuration of the backup MSC's 14-bit A interface signaling point configuration table is configured as follows:
  • the backup MSC does not have real activation data although it has configuration data for multiple signaling points on the A interface.
  • the backup MSC is configured with the local office A interface signaling point of Oxa 1, but on the mobile network,
  • the MSC with the Oxal signaling point is actually MSC1. Only when the MSC1 fails and the backup MSC takes over its network location, the backup MSC activates the Oxal signaling point as a 14-bit A interface signaling point in use by itself.
  • Step 4 Determine whether the backup MSC is in a fault state. If it is in a fault state, perform a switchover between the primary and backup MSCs so that the backup MSC can take over the services of the faulty MSC. In other words, during operation, if MSC1 fails, the backup MSC takes over MSC1.
