Embodiment 1

[0051] Such as figure 1 As shown, the flow chart of the call processing method provided by the embodiment of the present application includes the following steps:

[0052] S101: The network side device receives a voice call request, where the voice call request carries identification information of the called UE.

[0053] S102: If the network side device finds that the domain selection result of the called UE is the PS domain according to the identification information of the called UE, and the registration status is successful under the VoLTE service, then no longer query the location information of the called UE, and directly return Respond to the message.

[0054] In the specific implementation process, when the domain selection result of the called UE is the PS domain, the call data of the called UE may still be sent back from the 2G network, so the registration status of the called UE under the VoLTE service can be queried at the same time. If the network side device d...

Embodiment 2

[0061] Such as figure 2 As shown, the process of UE-A calling UE-B under the VOLTE service environment provided by the embodiment of the present application, wherein, the network device with the letter O is the network device on the calling side, such as the S-CSCF network element (O) , VOLTE AS(O) and SCP AS(O), the network device with the letter T is the network device on the called side, such as S-CSCF network element(T), VOLTE AS(T) and SCP AS(T), the call The process includes:

[0062] 1. When UE-A dials the short number of UE-B, UE-A sends an INVITE message to the S-CSCF network element (O).

[0063] Among them, the P-Access-Network-Info header field in the INVITE message carries the location information of UE-A: utran-cell-id-3gpp=MCC+MNC+TAC+ECI, in addition, the location information of UE-A can also be It is identified by the ECGI of UE-A.

[0064] 2. The S-CSCF network element (O) receives the INVITE message sent by UE-A, and when it determines that it has stored...

Embodiment 3

[0097] Based on the same inventive concept, the embodiment of the present application also provides a call processing device corresponding to the call processing method. Since the problem-solving principle of the device is similar to the call processing method of the embodiment of the present application, the implementation of the device can refer to the method The implementation of the implementation, the repetition will not repeat them.

[0098] Such as image 3 As shown, it is a structural diagram of the call processing device provided in the embodiment of the present application, including:

[0099] The receiving module 301 is configured to receive a voice call request, the voice call request carrying identification information of the called user terminal UE;

[0100] Returning module 302, for if according to the identification information of the called UE, it is found that the domain selection result of the called UE is a packet switched PS domain, and it is in a success...

Abstract

The present application relates to the field of mobile communication technology, and in particular to a call processing method and device, which are used to solve the problem that the process of obtaining the location information of the called user in the VoLTE service in the prior art will increase the network overhead in the paging process and prolong the call connection. The problem of delay; the call processing method provided by the embodiment of the present application includes: the network side equipment receives the voice call request, if according to the identification information of the called UE in the voice call request, the domain selection result of the called UE is found to be PS domain, And in the successful registration state under the VoLTE service, the location information of the called UE is no longer inquired, and a response message is returned directly. Here, when the network side device determines that the domain selection result of the called UE is the PS domain, and under the VoLTE service, it is In the successful registration status, it can be determined that the called UE is in the VoLTE service environment. At this time, the response message can be returned directly without querying the location information of the called UE, so it can save network overhead in the call process and reduce call connection delay. .

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a call processing method and device. Background technique [0002] At present, the voice call (Voice over LTE, VoLTE) service on the long-term evolution has become increasingly mature, but in order to inherit the original 2G / 3G services, some VoLTE services, such as city exceptions, border roaming, etc., need to obtain the location information of the called user It is used when generating call bills, and the process of obtaining the location information of the called user in the VoLTE service will increase network overhead and prolong the call connection delay. [0003] Taking the intelligent network platform as an example, in the intelligent network platform, a voice call request is first initiated by user equipment (User Equipment, UE)-A, and when the voice call request reaches the service control point application server (Service Control Point Applic...
