摘要： The present invention discloses a method, system, Base Station Subsystem (BSS), and Mobile Switching Center (MSC) for data transmission, and pertains to the communication field. The method includes: The BSS negotiates a redundancy level with the MSC through a redundancy level negotiation message, and chooses a redundancy level; and the BSS generate a redundancy packet according to the chosen redundancy level and sends the redundancy packet to the MSC. The system includes a BSS and an MSC. The BSS includes: a sending module, a first receiving module, a decision-making module, and a redundancy data generating module. The MSC includes a second receiving module and a responding module. In the technical solution under the present invention, the probability of user data loss as a result of packet loss is substantially reduced in AoIP, and the QoS of the voice service and the CSD service is improved.

摘要： A method for establishing a bearer for a GSM network is disclosed in embodiments of the present invention. The method includes: receiving, by a Media Gateway, a message for adding a wireless side end point, assigning an IP address and a port number for a call and transmitting a response message containing the IP address and the port number assigned for the call; acquiring, by the Media Gateway, the IP address and the port number assigned for the call by the Base Station Controller via the Mobile Switching Center Server and establishing an IP bearer with the Base Station Controller. A device and a system for establishing a bearer for a GSM network are also disclosed in embodiments of the present invention. With the present invention, a full or part path transcoder-free operation may be realized, which can avoid quality reduction and transmission delay caused by multiple transcodings of voice and save TC resources and transmission resources.
