    摘要： The present invention relates to the communications field and discloses a method, a device, and a system for controlling a voice encoding rate. The method includes: receiving a call pre-handover notification, where the call pre-handover notification carries a voice encoding type used by a local mobile station MS after a call handover; and setting a rate adjustment indication according to the voice encoding type used by the local MS after the call handover, and sending the rate adjustment indication to a peer MS, so that the peer MS performs voice encoding according to the rate adjustment indication until the local MS completes the call handover. The device includes a receiving module, a setting module, and a sending module. In the present invention, a rate adjustment indication is set according to a voice encoding type used by a local MS after a call handover, and the rate adjustment indication is sent to a peer MS, so that the peer MS performs voice encoding according to the rate adjustment indication, thereby avoiding silence caused by a local MS's failure in receiving a high-rate voice frame sent by the peer MS.

    摘要： Embodiments of the present invention provide methods, devices, and a system for assigning and releasing satellite bandwidth and relate to the communications field, so that satellite bandwidth can be assigned and released in time, thereby ensuring effective bandwidth usage and saving bandwidth resources. The method for assigning bandwidth includes: before a user plane is established in a signaling interaction process for initiating a service, sending a bandwidth assignment request for the service to a satellite device connected through an interface, so as to assign satellite bandwidth for the service. The method for releasing bandwidth includes: before the user plane is released in a signaling interaction process for initiating the service, sending a bandwidth release request for the service to the satellite device connected through the interface, so as to release satellite bandwidth for the service. The embodiments of the present invention are applicable to satellite bandwidth assignment and release.

    摘要： A method, a device, and a system for call handover and call processing are provided. The method for call handover includes the following steps. An add endpoint request message is sent to a media gateway (MGW), in which the add endpoint request message carries endpoint information about a Time Division Multiple (TDM) type and codec information that corresponds to the TDM type, and endpoint information about an Internet Protocol (IP) type and codec information that corresponds to the IP type. An add endpoint reply message indicating that the MGW successfully establishes a TDM endpoint and an IP endpoint is received, and a Handover Request message carrying a circuit identifier code (CIC) information element and the endpoint information about an IP type is sent to a target Base Station Controller (BSC). A Handover Request Acknowledge message carrying the endpoint information about a TDM type or the endpoint information about an IP type returned by the target BSC is received. A call failure case caused by different between TDM endpoints individually assigned by the target BSC and a core network (CN) side can be prevented, thereby increasing a call success rate.

    摘要： A method, a system, and a Mobile Switch Center, MSC, for lawful interception are disclosed by the embodiments of the present invention. The method for lawful interception includes: when a local switch of a speech path between a first terminal and a second terminal is established in a Base Station Sub-system, BSS, or after the local switch of the speech path between the first terminal and the second terminal is established in the BSS, instructing the BSS to output a bypassing to the MSC to perform lawful interception about the speech path. Through the method, the system, and the MSC for lawful interception in the present invention, the speech path between two terminals is connected to the MSC from the BSS, so that the bypassing is led out from the MSC for an interception system to perform lawful interception. The method will not cause speech interruption on the speech path between the two terminals that has a local switch established, or may greatly shorten the time of speech interruption, so that a user that is monitored cannot be easily aware that the speech path is monitored.
