CRS Customized Ringing Signal 4 Customized Ringing Signal (CRS) 4.1 Introduction The CRS service is an operator specific
42、 service by which an operator enables the subscriber to customize the media which is played to the called party during alerting of the called party. The media can consist of music, voice, text, video or other customized ringing signals. 4.2 Description 4.2.1 General description The service user is a
43、ble to subscribe to the CRS service, activate (or de-activate) the service, and update the settings, e.g., to change by configuration the active CRS media. The media can consist of favourable songs, multimedia clips or other customized ring signals. The CRS subscriber is able to refine the CRS media
44、 selection behaviour with configured rules, e.g. time, calling partys location, called partys location, the identity of the calling and called party. The CRS service is able to select the appropriate CRS media according to the rules. CRS is an originating network service, but can also have a termina
45、ting network functional component. That is, CRS media can be selected on behalf of the calling subscriber, but the called (IMS) subscriber can also subscribe to and activate the CRS service. Whether or not the called partys CRS media has precedence over the calling partys selected CRS media is a mat
46、ter of configuration in the called partys (terminating) network. The presentation of the selected CRS media to the called party starts some time following the initiation of a session, but prior to session answer. When the called party answers, the CRS media either stops or continues during the conve
47、rsation, depending on operator or user preferences. 4.3 Operational requirements 4.3.1 Provision/withdrawal 4.3.1.1 CRS provision/withdrawal The CRS service may be provided after prior arrangement with the service provider. The CRS service may be withdrawn at the subscribers request or for administr
48、ative reasons. 4.3.1.2 Requirements on the originating network side The originating network side may support the “early-session“ extension as described in RFC 3959 7.For the early session model, if the CRS service is provided by the originating network, the CRS AS shall control an MRF as described i
49、n 3GPP TS 24.229 3 that is acting on behalf of a calling subscriber who has activated CRS. The CRS service implementing the download and play model adds no additional requirements on the originating network side. 4.3.1.3 Requirements on the terminating network side The terminating network side may support the “early-session“ extension as described in RFC 3959 7. NOTE: the CRS service implementing the early-session model needs the early-session extension to be supported by intermediate entities and the terminating UE, else CRS media can
