Embodiment 1

[0095] Embodiment 1: The calling user and the called user are currently in different networks. These include:

[0096] (1) The origin of the calling party and the called party are the same, and one of the calling party and the called party roams, so that the current network of the calling party and the called party is different;

[0097] (2) The origin of the calling party and the called party are the same, and both the calling party and the called party are roaming, but the roaming areas are different, so that the calling user and the called user are currently in different networks;

[0098] (3) The origin of the calling party and the called party are different, there is no roaming, and the current network of the calling user and the called user is different;

[0099] (4) The origin of the calling party and the called party are different, wherein the calling party or the called party roams or both roam, but the roaming area is different, so that the current network of the ca...

Embodiment 2

[0126] Embodiment 2: The current network of the calling user and the called user is the same network. These include:

[0127] (1) The origin of the calling party and the called party are different, the calling party roams to the called land; or the called party roams to the calling land; or both the calling party and the called party roam in the same network;

[0128] (2) The origin of the calling party and the called party are the same, and both the calling party and the called party roam to the same network.

[0129] The network diagram is as follows Figure 7 As shown, it includes: the base station subsystem (calling BSS) of the network where the calling party is currently located, the calling mobile switching center (calling MSC), the called home HLR, the called mobile switching center (called MSC), and the called The base station subsystem (called BSS) of the network, the CRBT platform of the network where the caller is currently located, and the centralized information...

Abstract

The method includes steps: through mobile switching center MSC of current network, calling party initiates a call; after receiving ringing message from called party, the MSC in current network the calling party locates initiates a call to color ring platform in current network the calling party locates; obtaining information of color ring customized by the called party, the color ringing platformplays corresponding ring back tone to the calling party. The invention does not need to switch the call back to home network of the called party to play color ringing. When called party and calling party are in same network, implementing call and playing color ringing can be realized in same network directly. Thus, there is no circuitous channel so as to save resources of system channel.

Description

technical field [0001] The invention relates to the field of communication, in particular to a ring-back tone playing method. Background technique [0002] The ring back tone service is a service that allows the phone user to customize the ring back tone.
