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 (Voice over Long Term Evolution), and provides an automatic delimiting method and device for a VoLTE call connection problem. The method comprisesthe steps that 183 retransmission caused by unavailability of wireless resources is judged according to second signaling characteristics of a Gm interface, one reason why the wireless resources are unavailable is that the resources are not activated, the SAE-GW informs an MME to be activated after a PCRF sends an RAR message to the SAE-GW in the connection process, and therefore and according tothe association between the second signaling feature of the Gm interface and the first signaling feature of the Mw interface, the problem that the SAE-GW is finally positioned as the SAE-GW due to thefact that the SAE-GW does not respond to the RAR message and cannot activate the bearer resource of the base station is solved. Call features corresponding to each type of questions are sorted out byutilizing existing network experience summary and case summary to form a delimitation feature code library, and the delimitation feature code library is stored in the form of call feature codes to finally realize final delimitation of the connected questions.

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...
