Method for registering IMS user public ID and recessive registration in IP multimedia subsystem

Abstract

The invention discloses a method for registering an IMS user's public ID and an implicit registration in an IP multimedia subsystem, wherein the method for registering an IMS user's public ID includes the following steps: setting a shared attribute element of the IMS user's public ID to indicate the IMS user The public ID is shared with all IMS user private IDs of the subscriber or shared with some IMS user private IDs; the user equipment under a subscriber with the fixed private ID of the first IMS user initiates a request to the core network to register the public ID of the first IMS user; the core The network-related component agrees or rejects the registration of the first IMS user public ID by the user equipment according to the original associated IMS user private ID and the shared attribute element of the first IMS user public ID; if agreed, the core network-related component returns the consent After the user equipment registers the response of the first IMS user public ID, the user equipment completes the registration. The invention satisfies the user's requirement for partial sharing, saves network resources and improves service quality.

Description

Technical field [0001] The invention relates to the technical field of IP Multimedia Subsystem (IMS), in particular to the technical field of IMPU (IMS Public User Identity, IMS user public ID) sharing and implicit registration in the IP Multimedia Subsystem. Background technique [0002] In the IMS domain, multiple IMPUs are allowed to be associated with an ISIM (IP Multimedia Services Identity Module) card, and multiple IMPUs are allowed to be registered at one time when the terminal uses the IMSI card. This mechanism is called hidden Sex registration mechanism. [0003] At the same time, in the IMS domain, users are allowed to set one IMPU as shared based on using multiple ISIM cards, so that in addition to the ISIM originally associated with the IMPU, other ISIMs can also use the IMPU. This mechanism is called a sharing mechanism. [0004] In the IMS domain, a subscriber (Subscriber) refers to an entity that uses a service, which is equivalent to a user referred to in the CS ...

AI Technical Summary

Problems solved by technology

[0024] 1. The user's protection requirements for sharing cannot be met. When the user requires that the sharing only take effect in some UEs but not in other UEs, it cannot be realized through the existing sharing mechanism

In the above example 1, if the son is a minor, the father may order adult services or other services that the son does not want to use through an IMPU, and the father wants the mother to share these services, the father cannot The IMPU is set to be shared, otherwise the son can use it; in addition, there is also a need for the father to set his communication number to be shared, so when others cannot contact the father, the server will automatically contact the mother; the problem is that there is also a connection If it is not the case of the mother, it is necessary to contact the son at this time, but if the father does not want to disturb the son's study, he cannot share the IMPU

[0025] 2. The sharing characteristics of services are reduced. Sharing means that many people or UEs can share one or some services, but the global nature of sharing brings the following two problems:

[0047] It leads to some unpleasant user experiences. When a certain IMPU in a user's implicit registration set is set to be shared, it means that other IMPUs in the implicit registration set must also be set to be shared at the same time; If it is shared, it is another kind of contradiction for the user; on the other hand, if the user sets an IMPU as shared at the beginning, and then puts it and several other non-shared IMPUs in an implicit registration set, it will also The same problem exists, and if the user is not aware of this problem, it will lead to results that some users do not want, which may be unbearable for the user, and it also means that the sharing characteristics of the service are reduced
