Problems solved by technology

[0006] But as mentioned above, the calling user who initiates the call does not know whether the called user is in the roaming state, so he may call the called user at any time, including some unimportant calls
As a result, the called user in the roaming state has to answer various incoming calls and has to bear the roaming call charges, even if some calls are unnecessary

Embodiment Construction

[0030] The present invention judges the roaming state of the called user by the network side, and when the calling user calls the called user, when the network side judges that the called user is in the roaming state, the roaming state and information related to roaming (collectively referred to as roaming state information) are provided. For the calling user, it is convenient for the calling user to decide whether to continue the current call. For the convenience of description, the service of providing roaming status information to the calling user is called the roaming status indication service of the called user. The present invention will be described in detail below with reference to the accompanying drawings.

[0031] like figure 1 It shows the networking diagram of the first embodiment for realizing the roaming state indication service of the called user, in which only the network entities closely related to the present invention are shown, including:

Abstract

The method comprises: the calling side initiates a call to the called side; the network side receives the call to the called side and decides if the called side is at roaming state; if yes, sending the information about the called side being at roaming state to the calling side to prompt him, and when called side is at roaming state, determining the roaming area where the called side locates at; finally, adding the information describing the roaming position of called side into the roaming state information, and sending it to the calling side. The invention also reveals a system for indicating the roaming state of user.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a system for indicating a roaming state of a called user. Background technique [0002] The mobile communication system provides users with roaming capabilities, and users can communicate in different places and in different cellular network cells. [0003] When the called user is roaming, the calling user and the called user may be in different time zones. The time difference between the two time zones makes communication not always convenient, especially between the calling user and the called user. When the time difference of the area where the called user is located is relatively large (for example, one is at night and the other is in daytime). The time difference between the two parties leads to different work and rest times, so choosing an appropriate time to make a call becomes a very important factor. [0004] Usually, the calling user who init...
