Embodiment 1

[0048] Embodiment 1 of the present invention provides that the present invention provides an automatic demarcation method for the connection problem of a VoLTE call. The first failure interface of this call is the Mw interface, so first judge the error condition of this interface, and then correlate with the Gm interface Signaling features, just in the embodiment of the present invention, both the calling party and the called party are VoLTE users of the same network operator, and they are both registered in the VoLTE IMS network during the call, such as figure 1 shown, including:

[0049] In step 201, the first signaling feature of the Mw interface is obtained; wherein, the first signaling feature includes: statuscode_invite is 503, and carries Warning: "RAR message timeout".

[0050] In step 201, according to the first signaling feature of the Mw interface, it is judged that the RAR message is not responded by the PCRF or the SAE-GW, thereby limiting the problem node to eith...

Embodiment 2

[0060] Embodiment 2 of the present invention is to convert the corresponding character string into a value in Embodiment 1, and further complete the analysis and judgment process as background guarantee support, such as image 3 As shown, specifically:

[0061] In step 301, in the server, each stored character string is regarded as a numerical type for calculation, and the calculated numerical results determined for different positioning problems are divided into corresponding numerical intervals.

[0062] In step 302, if the numerical results corresponding to the two positioning problems are similar, or if the numerical results corresponding to the two positioning problems cannot be effectively divided into the numerical intervals divided by the server for the specified type of positioning problems, When the character string is generated, one or more bit values ​​are inserted at the specified bit positions, so that the converted numerical results corresponding to different po...

Embodiment 3

[0074] Such as Figure 7 As shown, it is a schematic diagram of the structure of the automatic demarcation device for the VoLTE call connection problem of the embodiment of the present invention. The apparatus for automatically demarcating the VoLTE call connection problem in this embodiment includes one or more processors 21 and memory 22 . in, Figure 7 A processor 21 is taken as an example.

[0075] Processor 21 and memory 22 can be connected by bus or other means, Figure 7 Take connection via bus as an example.

[0076] Memory 22, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs and non-volatile computer-executable programs, such as the automatic demarcation method for the VoLTE call connection problem in Embodiment 1 . The processor 21 runs the non-volatile software programs and instructions stored in the memory 22 to execute the automatic demarcation method of the VoLTE call connection problem.

Abstract

The invention relates to the technical field of VoLTE, and provides an automatic demarcation method and device for VoLTE call connection problems. The method includes, according to the second signaling feature of the Gm interface, judging that the wireless resource is unavailable, resulting in 183 retransmission, and one of the reasons for the unavailable wireless resource is that the resource is not activated, and the activation of the wireless resource is sent by the PCRF to the SAE-GW After sending the RAR message, the SAE-GW notifies the MME that it is activated. Therefore, according to the association between the second signaling feature of the Gm interface and the first signaling feature of the Mw interface, it can be concluded that the SAE-GW cannot be activated because the SAE-GW does not respond to the RAR message. The bearer resource of the base station is caused, and it is finally positioned as an SAE‑GW problem. The present invention summarizes the experience and cases of the existing network, sorts out the call features corresponding to each type of problem, forms a demarcation feature code library, stores them in the form of call feature codes, and finally realizes the final demarcation of the connection problem.

Description

【Technical field】 [0001] The present invention relates to the technical field of VoLTE, in particular to a method and device for automatically demarcating VoLTE calls. 【Background technique】 [0002] Voice over Long-Term Evolution (VoLTE for short) is an end-to-end voice solution based on all IP conditions on the 4G network, which means a high-speed wireless communication standard for mobile phones and data terminals. It is based on the IP Multimedia Subsystem (IMS for short) network, enabling voice services to be transmitted as data streams in the LTE data bearer network, without the need to maintain and rely on traditional circuit-switched voice networks. The most direct experience that VoLTE technology brings to 4G users is shorter connection waiting time, and higher quality, more natural voice and video call effects. With the vigorous promotion of VoLTE services by major operators, the number of VoLTE users has shown explosive growth. The increase in the number of users...
