Bearer establishment method, base station, packet data gateway, and computer system
First Claim
1. A bearer establishment method, comprising:
- receiving a device to device (D2D) mode indication requested by an application function entity or a proximity service server for a source user equipment (UE), the D2D mode indication indicating whether the source UE is in a first D2D connection establishment mode or a second D2D connection establishment mode, the first D2D connection establishment mode indicating that the source UE requires that a D2D connection is established preferentially over a common connection, and the second D2D connection establishment mode indicating that the source UE requires that the D2D connection must be established; and
according to the D2D mode indication, when the D2D connection can be established successfully, establishing the D2D connection for the source UE; and
according to the D2D mode indication, when the D2D connection cannot be established successfully;
establishing the common connection for the source UE upon determining the D2D mode indication indicates the first D2D connection establishment mode, andfeeding back a connection establishment failure response to the application function entity or the proximity service server upon determining the D2D mode indication indicates the second D2D connection establishment mode.

Abstract
The present invention provides a bearer establishment method, a base station, a packet data gateway, and a computer system, where the bearer establishment method includes: receiving a D2D mode indication requested by an AF entity or a proximity service server for a source UE, where the D2D mode indication includes a first D2D connection establishment mode or a second D2D connection establishment mode; and according to the D2D mode indication, when a D2D connection can be established successfully, establishing the D2D connection for the source UE; or when a D2D connection cannot be established successfully, establishing a common connection if the D2D mode indication is the first D2D connection establishment mode, and feeding back a connection establishment failure response to the AF entity or the proximity service server if the D2D mode indication is the second D2D connection establishment mode.

7. A bearer establishment method, comprising:
sending a device to device (D2D) mode indication requested by a user equipment (UE) to a base station, a packet data gateway, or a policy and charging rules function entity, the D2D mode indication indicating whether the UE is in a first D2D connection establishment mode or a second D2D connection establishment mode, the first D2D connection establishment mode indicating that the source UE requires that a D2D connection is established preferentially over a common connection, and the second D2D connection establishment mode indicating that the source UE requires that the D2D connection must be established, so that the base station, the packet data gateway, or the policy and charging rules function entity; according to the D2D mode indication, when the D2D connection can be established successfully, establishes the D2D connection for the UE; and according to the D2D mode indication, when the D2D connection cannot be established successfully; establishes the common connection for the UE upon determining the D2D mode indication indicates the first D2D connection establishment mode, and feeds back a connection establishment failure response upon determining the D2D mode indication indicates the second D2D connection establishment mode. - View Dependent Claims (8, 9)

10. A base station, comprising:
-
at least one hardware processor; a memory interfaced to the at least one hardware processor, the memory including instructions controlling the at least one hardware processor to implement; a first receiving module, configured to receive a device to device (D2D) mode indication requested by an application function entity or a proximity service server for a source user equipment (UE), the D2D mode indication indicating whether the source UE is in a first D2D connection establishment mode or a second D2D connection establishment mode, the first D2D connection establishment mode indicating that the source UE requires that a D2D connection is established preferentially over a common connection, and the second D2D connection establishment mode indicating that the source UE requires that the D2D connection must be established; a first establishing module, configured to; receive the D2D mode indication from the first receiving module; according to the D2D mode indication; when the D2D connection can be established successfully, establish the D2D connection for the source UE, and when the D2D connection cannot be established successfully and the D2D mode indication indicates the first D2D connection establishment mode, establish a common connection for the source; and a first feedback module, configured to; receive the D2D mode indication from the first receiving module; and according to the D2D mode indication, when the D2D connection cannot be established successfully and the D2D mode indication indicates the second D2D connection establishment mode, feed back a connection establishment failure response to the application function entity or the proximity service server. - View Dependent Claims (11, 12, 13, 14)
