Embodiment 1

[0055] Based on the technical principle of the above invention, this application provides a communication method, such as figure 2 As shown, the method includes:

[0056] S204. The target IMS client sends a configuration update request to the DMS network element after the validity period of the SIP-DIGEST authentication password expires.

[0057] S205. The DMS network element executes a preset task in response to the configuration update request.

[0058] Wherein, the preset task includes the operation of making the IP multimedia subsystem home subscriber server IMS HSS network element update the SIP-DIGEST authentication password of the target IMS client to the target authentication password.

[0059] S206. After the IMS HSS network element updates the SIP-DIGEST authentication password of the target IMS client to the target authentication password, the DMS network element sends updated configuration information to the target IMS client; the updated configuration informatio...

Embodiment 2

[0100] Based on the same inventive concept as the above-mentioned Embodiment 1, this embodiment of the present application also provides a DMS network element, such as Image 6 As shown, the DMS network element 50 includes:

[0101] The receiving unit 501 is configured to receive the configuration update request sent by the target IMS client after the validity period of the SIP-DIGEST authentication password expires;

[0102] The processing unit 502 is configured to execute a preset task in response to the configuration update request; the preset task includes an operation of causing the IMSHSS network element to update the SIP-DIGEST authentication password of the target IMS client to the target authentication password;

[0103] The sending unit 503 is configured to send updated configuration information to the target IMS client after the IMS HSS network element updates the SIP-DIGEST authentication password of the target IMS client to the target authentication password; the ...

Abstract

The embodiment of the invention discloses a communication method and device, and relates to the field of communications. According to the invention, the target authentication password in the update configuration information sent to the IMS client by the DMS network element can be ensured to be consistent with the SIP-DIGEST authentication password of the target IMS client recorded in the IMS HSS network element, so the problem of authentication failure caused by incorrect SIP-DIGEST authentication password is avoided. The method comprises the steps that a DMS network element receives a configuration updating request sent by an IMS client of a target IP multimedia subsystem after the validity period of an SIP-DIGEST authentication password is expired; the DMS network element responds to theconfiguration updating request and executes a preset task, wherein the preset task is used for enabling an IP multimedia subsystem home subscriber server IMS HSS network element to update an SIP-DIGEST authentication password of a target IMS client into a target authentication password; the DMS network element sends update configuration information to the target IMS client after the IMS HSS network element updates the SIP-DIGEST authentication password of the target IMS client into the target authentication password, wherein the update configuration information comprises the target authentication password.

Description

technical field [0001] The present application relates to the communication field, and in particular to a communication method and device. Background technique [0002] The voice service solution based on the IP Multimedia Subsystem (IMS) is the main implementation scheme for operators' 4G / 5G network voice services. The IMS system is implemented based on the Session Initiation Protocol (SIP). There are two IMS user authentication methods: Authentication and Key Agreement (AKA) based on the Subscriber Identity Module (SIM) card authentication, and SIP-DIGEST authentication (see RFC3261). Among them, SIP-DIGEST authentication is similar to the authentication name / password authentication method widely used in the existing mobile Internet, and its most important authentication factors are user name and password. application offers the possibility. [0003] In the prior art, the IMS client is used to periodically send a configuration request to a terminal management server (De...
