Embodiment Construction

[0034] Such as figure 1 As shown, in one embodiment, a method for automatically opening VoLTE HD voice is provided, the method comprising:

[0035] In step 102, the inquiry call session control function I-CSCF receives the IMS registration request sent by the terminal, and initiates a user authorization request to the home subscriber server HSS.

[0036] CSCF (Call Session Control Function, Call Session Control Function) is an internal functional entity of IMS (IP Multimedia System), and is the core of the entire IMS network. This network element is mainly responsible for the control of functions such as registration, authentication, session control, routing management, network management, and billing, which are closely related to user services. The I-CSCF (Interrogating CSCF) is the entry point of the IMS home network. During the registration process, the I-CSCF selects an S-CSCF for the user by querying the HSS. During the call process, the call to the IMS network is first...

Abstract

The invention relates to a method for automatic Voice over Long-Term Evolution (VoLTE) provisioning. The method comprises the following steps: an interrogating-call session control function (I-CSCF) receives an IMS registration request sent by a terminal, and sends a user authorization request to a home subscriber server (HSS); the HSS receives the user authorization request, and judges whether auser has subscribed to VoLTE data or not; and if the user has not subscribed to the VoLTE data, the HSS sends a notification message to a business and operation support system (BOSS), so that the BOSSsubscribes to the VoLTE data for the user according to the notification message. The method has the advantages that the automatic VoLTE provisioning can be achieved, so that the workload cost is reduced. Moreover, the invention further provides a system for the automatic VoLTE provisioning, and another method and device for the automatic VoLTE provisioning.

Description

technical field [0001] The present invention relates to the field of core network technology, in particular to a method, system and device for automatically enabling VoLTE high-definition voice. Background technique [0002] VoLTE (Voice over LTE) is defined by the 3GPP standard. Based on IMS (IP Multimedia Subsystem, IP multimedia system), it is a brand-new multimedia service form, which can meet the needs of current end customers for more novel and more diverse multimedia services. At present, it is considered to be the core technology of the next generation network, and it is also an important way to solve the convergence of mobile and fixed networks and introduce differentiated services such as voice, data, and video triple integration) The LTE voice solution of the network, that is, to provide in the LTE coverage area IP-based high-definition voice services. The most direct experience that VoLTE technology brings to 4G users is shorter connection waiting time, and high...
