  • Method and system for authenticating short message calling party
    Patent number: 7957754
    Abstract: A method for authenticating a Short Message (SM) calling party, including: if a Signal Relay Function for support of Mobile Number Portability (MNP-SRF) module detects a calling party number carried in an SM belongs to its serving network after receiving a Mobile Originated (MO) SM, the MNP_SRF module adds an identifier of the MNP_SRF module's network to the calling party number. A Short Message Serving Center (SMSC) determines whether the SM passes calling party authentication according to the fact that whether the calling party number carries an identifier of the SMSC's network. The invention provides a system for authenticating an SM calling party, including: a Mobile Switching Center (MSC), a calling MNP_SRF module, a Number Portability Database (NPDB) and a Short Message Serving Center (SMSC). The invention may avoid a mobile number having subscribed to a new network from using resources of the SMSC of a network to which the subscription has been canceled.

  • System and method for providing RBT in communication network
    Patent number: 7889856
    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.
