Problems solved by technology

Assuming that MSC Server allocates Call-IDs cyclically in ascending order of Call-ID values, when a call is released normally, and MSC Server and BSC fail to release the corresponding Call-ID values ​​occupied in time, the corresponding Call-ID values ​​of the call For the i-th (i≤232) call after allocation, the Call-ID value must be re-applied, but because the Call-ID value status is "Occupied", this call allocation will fail
In this way, the Call-ID values ​​on both sides of the BSC and MSC Server cannot be synchronized, which not only causes a waste of Call-ID resources, but also reduces the success rate and efficiency of call distribution and call switching

Embodiment Construction

[0062] The Call-ID in the embodiments of the present invention refers to the unique identifier of a specific call on the A interface connection between the MSC and the corresponding BSC, and the Call-ID is uniformly managed and allocated by the MSC. Such as figure 2 As shown, it is a GSM system architecture diagram of the present invention, and the following embodiments are all based on the GSM system after IP transmission is fully introduced.

[0063] Such as image 3 As shown, it is a flow chart of Embodiment 1 of the call release method provided by the embodiment of the present invention; this embodiment includes the following steps:

[0064] Step 101, when the network element detects that the call ID of the identified call is abnormal and / or the call is abnormal and / or receives an operation and maintenance requirement, release the resources related to the call, and change the status of the call ID from "occupied" to "idle" , sending an SCCP connectionless type request m...

Abstract

The embodiment of the invention discloses a call release method and a call release device. The method comprises the following steps of: when a network element detects that a call identifier for identifying a call is abnormal and / or the call is abnormal, releasing resources related to the call, and transmitting a signaling connection control part (SCCP) no-connection type request message to an opposite network element; and receiving an SCCP no-connection type acknowledgement message from the opposite network element, wherein the opposite network element is used for releasing the resources related to the call on an opposite network element side. According to the call release method and the call release device in the embodiment of the invention, the call identifier for identifying the call and the resources related to the call are released simultaneously, so that the call identifier can be effectively utilized, and the success rates of flows such as call switching, call distribution and the like are increased.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a call release method and device. Background technique [0002] The Global System for Mobile communication (GSM for short) initially transmits signals based on a time division multiplexing (Time Division Multiple, TDM for short) transmission mode. Later, with the continuous development and popularization of Internet Protocol (Internet Protocol, referred to as IP) technology, the core network (Core Network, referred to as CN) has fully realized IP, and introduced the A interface signaling plane IP between CN and access network. Transmission SIGTRAN, the architecture diagram of the GSM system is as follows figure 1 As shown, the dotted line represents the signaling plane (Signaling), and the solid line represents the user plane (User plane). In this architecture, only the user plane of the A interface still adopts the TDM mode, which becomes the last obstacle for the whole net...
