Embodiment Construction

[0042] Since the terminal accessed through the non-DTM wireless access network cannot realize the coexistence of the PS service and the CS service, in order to realize the calling chromatic image service when this type of user terminal is called, the embodiment of the present invention uses , the network side first establishes a PS connection with the user terminal, and sends a multimedia description carrying chromatic image information to the user terminal, and the terminal obtains the chromatic image according to the description and saves it locally. CS call request, after receiving the CS call request, the terminal plays the stored chromatic image while ringing, thus solving the above-mentioned problem.

[0043] The network side initiates the establishment of a PS connection with the terminal, and the terminal obtains the chromatic image, and the terminal needs to keep the PDP (PacketData Protocol, packet data protocol) context active,

[0044] There are many ways to keep t...

Abstract

The invention discloses a method and a device for realizing a calling polychrome service in the IMS network, wherein, the method comprises that the polychrome is obtained by wireless access to the network access terminal by the non DTM double transitive mode and the polychrome is provided by a network side to the terminal; the obtained polychrome is stored; the voice call request messages of the circuit switched domain are received and the messages are sent by the network side to the terminal; the terminal ringing simultaneously broadcasts the stored polychrome to realize the calling polychrome service of the terminal. By the method and device proposed by the embodiment of the invention, when the called receives the voice calling request, the calling polychrome service of the network access terminal by the non DTM is realized by the pre-stored polychrome of the broadcast terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for realizing calling color image service in an IMS network. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) adopts the packet domain (PS) to provide bearer channels for its upper layer control signaling and media transmission, uses the SIP protocol as the service control protocol, and uses the simple, easy to expand, and convenient media combination of the SIP protocol It provides users with rich multimedia services by separating service control and bearer control; the main functional entities of the IMS network include the call control entity CSCF that controls functions such as user registration and session control, and the CSCF that provides various service logic control functions. Application server AS, home user server HSS for centralized management of user subscription data, and MGCF media gateway control function / IM-MGW ...
