Method for selecting bearer mode, packet gateway, and policy and charging rule function entity
First Claim
1. A method for selecting a bearer mode, comprising:
- receiving, by a packet gateway in a core network, indication information from a mobile terminal, wherein the indication information includes air interface transmission modes supported by the mobile terminal for establishing a session with the core network;
receiving an enhanced policy and charging control rule (PCC rule) sent by a policy and charging rule function (PCRF) entity in the core network, wherein the enhanced PCC rule comprises;
(a) at least one service flow of the mobile terminal, and (b) an air interface transmission mode associated with each service flow of the mobile terminal;
determining, according to the indication information and the enhanced PCC rule, an appropriate air interface transmission mode allowed to be used by one of a plurality of bearers of the mobile terminal, wherein each bearer is bound with one or more of the at least one service flow of the mobile terminal; and
sending a session establishment reply message to a serving gateway to which the mobile terminal belongs, wherein the session establishment reply message comprises the determined appropriate air interface transmission mode allowed to be used by the bearer.

Abstract
The present invention provides a method for selecting a bearer mode, a packet gateway, and a policy and charging rule function entity, relating to the field of communications technologies, and solving the problem that a base station selects a suitable air interface transmission mode for a bearer of a mobile terminal. Indication information of an air interface transmission mode supported by a mobile terminal is received. According to the indication information and a received enhanced policy and charging control rule that is sent by a policy and charging rule function entity, an air interface transmission mode allowed to be used by a bearer bound with a service flow of the mobile terminal is determined. A session establishment reply message is sent to a serving gateway to which the mobile terminal belongs, where the session establishment reply message comprises the air interface transmission mode allowed to be used by the bearer.

9. A method for selecting a bearer mode, comprising:
-
receiving, by a policy and charging rule function (PCRF) entity in a core network, a session establishment message sent by a packet gateway in the core network, wherein the session establishment message comprises indication information sent from a mobile terminal, wherein the indication information includes air interface transmission modes supported by the mobile terminal for establishing a session with the core network; generating an enhanced PCC rule for at least one service flow of the mobile terminal according to the indication information and a policy and charging setting that corresponds to the mobile terminal, wherein the enhanced PCC rule comprises;
(a) the at least one service flow of the mobile terminal, and (b) an air interface transmission mode associated with each service flow of the mobile terminal; andsending the enhanced PCC rule to the packet gateway, wherein the enhanced PCC rule is used for the packet gateway to determine, according to the indication information and the enhanced PCC rule, an appropriate air interface transmission mode allowed to be used by one of a plurality of bearers bound with the at least one service flow of the mobile terminal, wherein each bear of the mobile terminal is bound with one or more of the at least one service flow. - View Dependent Claims (10)
