Embodiment Construction

[0048] In order to provide an alternative to the existing method for establishing a handover bearer, so as to make the method for establishing a handover bearer more diversified, the present invention provides a method for establishing a handover bearer, as shown in FIG. 5 , including the following main steps:

[0049] S1. The MSC of the outgoing office and the MSC of the incoming office call the SDP information of the offices where both parties are located after the handover is interactive.

[0050] During the process of establishing an inter-office call for handover, the outgoing MSC interacts with the incoming MSC, so that the outgoing MSC learns the SDP information corresponding to the bearer resources allocated by the incoming MSC for establishing inter-office handover, and makes the incoming call The office MSC obtains the SDP information of the bearer channel of the other party of the call.

[0051] S2. The outgoing MSC uses the SDP information of the incoming MSC to pe...

Abstract

The utility model discloses a method for the establishment of switching bearing, which provides an alternative proposal of prior method for switching bearing, further solving the problem that the prior method for switching bearing can lead to insignificant waste of bearing resources. The utility model comprises: A. SDP information in offices of a switch-out office MSC and a switch-in office MSC called by the two offices after interactive switching; B. The switch-out office MSC calls MSC of the other party using the SDP information of the switch-in office for media re-negotiation, and builds the bearing between the switch-in office and the MSC of the other party. The utility model has advantages of building switching bearing in another method and further avoiding insignificant waste of bearing resources by implementing the method.
