Abstract: Embodiments of the present invention provide a method and an apparatus for scheduling a voice service in a packet domain. The method includes: obtaining at least one value of a first scheduling parameter corresponding to each protocol sublayer of L2 of a voice service, determining a condition needing to be satisfied by quality of service of the voice service, determining a value of a service scheduling parameter of the voice service based on the condition needing to be satisfied by the quality of service of the voice service and based on the at least one value of the first scheduling parameter, and scheduling the voice service based on the value of the service scheduling parameter of the voice service. In this way, a service scheduling parameter is adjusted at an appropriate time when a particular condition is satisfied, so that transmission quality of a link can be ensured.

Abstract: A method of bearer deletion is provided to improve the universality of the bearer deletion process. The method includes: receiving, by the original intermediate NE, the cancellation type indication parameter sent by the HSS, and deleting the bearer between the serving gateway (S-GW) and a packet data network gateway (P-GW), if the original intermediate network element obtains an attach type according to the cancellation type indication parameter indicating an attach type and a corresponding bearer exists on the original intermediate NE. This method helps efficiently improve the universality of the bearer deletion flow.
