Embodiment 1

[0049] like figure 1 As shown, it is a flowchart of a method for implementing VoLTE IMS registration provided by Embodiment 1 of the present application, including the following steps:

[0050] S101: During the process of requesting to attach to the EPC network side, the UE determines a first authentication parameter for initiating authentication to the IMS network side;

[0051] Specifically, the first authentication parameter for initiating authentication to the IMS network side may be determined in the following manner: after sending the attach request message to the EPC network side, receiving the four-tuple authentication vector sent by the EPC network side The authentication request, and according to the four-tuple authentication vector, calculate the number of responses, and determine the number of responses as the first authentication parameter for initiating authentication to the IMS network side.

[0052] S102: After successfully attaching to the EPC network, send a...

Embodiment 2

[0056] like figure 2 As shown, the flow chart of the method for implementing VoLTE IMS registration provided by Embodiment 2 of the present application includes the following steps:

[0057] S201: The IMS network side receives a registration request message sent by the UE after successfully attaching to the EPC network, wherein the registration request message carries a first authentication parameter for initiating authentication to the IMS network side, and the first authentication parameter It is determined by the UE during the process of requesting to attach to the EPC network.

[0058] S202: Obtain a second authentication parameter used to verify the first authentication parameter from the EPC network side.

[0059] Specifically, the IMS network side may send a multimedia authentication request MAR message to the EPC network side, for requesting to obtain authentication information used to verify the first authentication parameter, and may subsequently receive the second...

Embodiment 3

[0065] refer to image 3 , in order to better illustrate the solution proposed by the embodiment of the present application, the process of UE attaching to the EPC network and registering in the IMS network will be described in detail in Embodiment 3 of the present application.

[0066] The process of UE attaching to the EPC network:

[0067] S301: The UE sends an Attach Request (Attach Request) message to a Mobile Management Entity (Mobile Management Entity, MME) through the eNodeB, wherein the Attach Request message carries user identity information, such as an International Mobile Subscriber Identification Number (International Mobile Subscriber Identification Number , IMSI), etc., and the user's ability to access the core network, attachment type and other information.

[0068] S302: If the MME does not have an authentication set locally, the MME sends an Authentication Information Request (AIR) message to a Home Subscriber Server (HSS) to request authentication data.

Abstract

The invention relates to the field of mobile communication technology, in particular to a method and device for realizing VoLTE IMS registration, used for solving the problem that VoLTE IMS registration success rate is relatively low in the prior art. The method provided by the embodiment of the invention for realizing the VoLTE IMS registration comprises the following steps: determining a first authentication parameter used for initiating authentication to an IMS network side of an IP multimedia subsystem in a process that user equipment (UE) requests to be attached to an EPC network side; after the UE is successfully attached to the EPC network, sending a registration request message carrying the first authentication parameter to an IMS network side; and receiving a successful registration message sent by the IMS network side, wherein the successful registration message is sent to the UE after the IMS network side determines a fact that the first authentication parameter is consistent with a second authentication parameter obtained from the EPC network side.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for realizing VoLTE IMS registration. Background technique [0002] Registration is a process in which a user equipment (User Equipment, UE) requests a subscription network for authorization to use a service. Once the UE is successfully registered, the user can initiate and receive sessions and perform services. [0003] At present, a process for a UE supporting a voice over LTE (VoLTE) bearer to register with a network side is divided into two stages. First, the UE needs to be attached to the 4G core network (Evolved Packet Core, EPC), and then complete the registration of the IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) network. Among them, when the UE completes the registration of the IMS network, it needs to initiate two registration processes: the UE initiates the registration process with the IMS network for the first tim...
