Embodiment 1
[0040] The embodiment of the present invention provides a calling method. figure 1 It is a schematic flow chart of the call method in Embodiment 1 of the present invention; figure 1 As shown, the method includes:
[0041] Step 101: After receiving the caller routing request from the user, the GMSC sends a map request message to the MNP network element; the map request message includes the calling number, called number and call announcement function label.
[0042] In this embodiment, the call playback function represented by the call playback function label can be customized, for example, it does not support the caller playback function, or supports the caller playback function, or supports the caller for a specific called user. Playback function and so on.
[0043] Step 102: When the MNP network element determines that the call announcement function is enabled based on the map request message, determine the caller announcement attribute corresponding to the calling number b...
Embodiment 2
[0065] The embodiment of the invention also provides a calling system. figure 2 It is a schematic diagram of the composition and structure of the call system in Embodiment 2 of the present invention; figure 2 As shown, the system includes: GMSC 21 and MNP network element 22; wherein,
[0066] The GMSC 21 is configured to send a map request message to the MNP network element 22 after receiving the caller routing request from the user; the map request message includes a calling number, a called number, and a call playback function label; It is used to indicate whether to output the announcement prompt information based on the portability attribute corresponding to the called number in the map response message and the caller announcement attribute;
[0067] The MNP network element 22 is configured to determine, based on the map request message, that when the call announcement function is enabled, determine the calling announcement attribute corresponding to the calling number ...
Embodiment approach
[0069] As an implementation, the system also includes HLRDB24;
[0070] The MNP network element 22 is configured to search the HLRDB 24 based on the calling number, judge whether the calling number is a user of the local network, and generate the calling announcement attribute corresponding to the calling number based on the judgment result.
[0071] Specifically, for each communication system under the operator network, there is a corresponding set of communication equipment network, that is to say, if the operator is the mobile operator network, there is a set of communication system under the mobile operator network , including HLR under the mobile operator's network; and HLR is a database managed by mobile users, which is used to store and record the subscription information of users in the area under its jurisdiction, and dynamically update the location information of users, so as to provide the called service in the calling service. The user's network route. Based on th...
