Abstract: A method for implementing communication services includes: after receiving a call request, determining whether a user subscribes to an IP Centrex service and an intelligent network (IN) service according to the obtained subscription information of the user; if the user subscribes to the IP Centrex service and IN service, checking with an application server (AS) whether the call request is for an intra-group call; if the call request is for an intra-group call, performing corresponding service processing according to the checking result to implement discount charging on the intra-group call. By using the method of the present invention, if the user subscribes to the IP Centrex service and the IN service, no conflict occurs between the IP Centrex service and the IN service, and discount charging is implemented on the intra-group call. A network device and a mobile communication system are also provided.

Abstract: A method for realizing one card for multi-number service is disclosed, wherein the subscriber's card of the called terminal has a plurality of numbers, and the method comprises: determining the subscriber card information of the called terminal, the present activated number and the mobile switch center MSC_S based on the called number; connecting the call to the MSC_S based on the obtained routing information of the said MSC_S, and then performing the subsequent connection of the call based on the called subscriber card information. When calling a user experiencing one card for multi-number service, regardless the telephone number the user registers, the connection to the number that the user currently uses could always be realized, so as to obtain the calling or short message service targeted to the one card for multi-number service, that is, a plurality of number could be online concurrently.

Abstract: Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
