Problems solved by technology

After analysis, the inventor found that there is a technical requirement for local switching after the A interface is turned into IP, and when the A interface is turned into IP, the signaling and data of the A interface will be carried on the IP network, and the TDM transmission of the existing local switching mechanism The transmission format and transmission modules of the signaling plane and the data plane in the method cannot be applied to the IP-based transmission mode, such as the original equal-length packet into a variable-length IP packet, etc. Therefore, the IP-based In the future, the local switching mechanism based on TDM transmission will no longer be applicable

Embodiment Construction

[0055] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] like image 3 As shown, in the embodiment of the present invention, the local switching process after the A interface is IP-based is as follows:

[0057] Step 31. When the calling user and the called user belong to the same base station controller, determine whether the calling user and the called user belong to the same base station, and if so, perform step 32; otherwise, perform step 33.

[0058] Step 32: Establish a routing table and set the next hop address as the mobile station where the called user resides, and perform data exchange between the calling user and the called user in the same base station according to the established routing table.

[0059] Step 33: Establish a routing table and set the next hop address as the base station to which the called user belongs, and perform data exchange between the calling user and the called user...

Abstract

The invention discloses an A interface IP-based local exchange method. The method comprises the following steps that: when a calling user and a called user belongs to the same base station controller, whether the calling user and the called user belongs to the same base station is judged; if yes, a route list is established, a next hop address is set to be a mobile station to which the called user belongs, and the calling user and the called user exchange data in the same base station according to the established route list; and if not, the route list is established, the next hop address is set to be the base station to which the called user belongs, and the calling user and the called user exchange data in the same base station controller according to the established route list. By adopting the method and the equipment, the A interface IP-based local exchange mechanism can be achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a local exchange method and equipment after the A interface is turned into IP. Background technique [0002] The local switch (Local switch) is a switching mechanism applied in the GSM system (Global System for Mobile Communications, Global System for Mobile Communications) and using TDM (Time Division Multiple, Time Division Multiplexing) for transmission. In the case where both communicating parties belong to the same BTS (Base Transceiver Station, base station) or BSC (Base Station Controller, base station controller), data is only exchanged inside the BTS or BSC, and signaling goes to the core network. This local switching mode can save corresponding transmission resources. [0003] The local switching mechanism includes two modes: BSC local switching and BTS local switching. [0004] figure 1 It is a schematic diagram of the call circuit occupation of BSC local swit...
