The method of realizing volte service call-in in voip call based on android platform

Abstract

The invention discloses a method for achieving Volte service callin in a VoiP call based on an Android platform. The method comprises the following steps: creating and managing an ImsPhone object; the creation of the ImsPhone object comprises: looking up whether the ImsPhone object exists in CallManager after a PhoneBase receives an IMSService start broadcast; the management of the ImsPhone object comprises: creating an SipPhone object in the case of the VoiP call, adding Ringcall objects of the SipPhone in a RingingCalls list of the CallManager, updating the Ringcall of SIP in the RingingCalls list as a currently actual call Ringcall object, and reporting the call to an APP to process a new call. The method disclosed by the invention can be used for enabling an Android user to obtain a call request of Volte in the VoiP call, and the user can select to listen to or refuse the new call.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing Volte service call-in in a Voip call based on an Android platform. Background technique [0002] The fourth-generation wireless data network (Long Term Evolution, LTE) is a new generation of broadband wireless mobile communication technology that is currently the mainstream in the world. It is oriented to packet domain services and cannot provide circuit domain services like traditional 2G / 3G networks. Therefore, how to The voice service provided by the LTE network has become a concern of the industry. To this end, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) specification defines that the goal of LTE and mobile network evolution is to use the multimedia subsystem (IP Multimedia Subsystem, IMS) of the Internet protocol IP to provide multimedia voice services to users. When IMS is used as a service contr...

And also can't make Android user get the call request of Volte in Voip call in these schemes, to select processing (answer or reject), thereby make the user miss the information of new incoming call

[0004] Android natively has some deficiencies in the management of the volte processing object, that is, the Phone object ImsPhone for 4G calls. At present, according to the native logic, multiple ImsPhone objects are created to manage Volte, resulting in multiple ImsPhone Ringcall objects in the RingingCalls list of the CallManager. When a new Volte calls, the Ringcall objects of these ImsPhone objects will be updated at the same time, resulting in more than one incoming Ringcall object in the RingingCalls list. According to the original logic, the APP is not notified, and the incoming call is hung up directly.

And in this process, the ImsPhone object will be created multiple times, wasting system resources

In addition, one ImsPhone object is enough to handle all Volte calls, but multiple objects cause management confusion and system consumption, resulting in incorrect handling of Volte calls
