Embodiment 1

[0024] refer to figure 1 , shows a flowchart of steps of a method for selecting a bearer according to Embodiment 1 of the present invention.

[0025] The steps of the method for selecting a bearer in this embodiment include:

[0026]Step S102: The LTE base station receives the GPRS Tunneling Protocol data packet transmitted by the core network serving gateway.

[0027] Wherein, the GPRS Tunneling Protocol data packet includes a data packet header and a protocol data unit.

[0028] Step S104: the LTE base station obtains the TEID from the packet header of the GPRS Tunneling Protocol data packet.

[0029] The TEID is included in the data packet header. In this embodiment, the TEID is defined as: S1 interface user identifier, bearer identifier, and tunnel type indication information, that is, the TEID includes: S1 interface user identifier, bearer identifier, and tunnel type indication information. However, those skilled in the art should understand that in practical applicati...

Embodiment 2

[0036] refer to figure 2 , shows a flow chart of steps of a method for selecting a bearer according to Embodiment 2 of the present invention.

[0037] The specific steps of the method for selecting a bearer in this embodiment include:

[0038] Step S202: the LTE base station receives the transport layer address and TEID corresponding to each tunnel of each user equipment transmitted by the core network equipment.

[0039] Wherein, the TEID corresponding to each tunnel of each user equipment on the core network side may be only an identifier, or may be a TEID composed of a bearer identifier or other information, and the present invention does not limit the information carried in the TEID. The transport layer address and tunnel identifier corresponding to each tunnel of each user equipment transmitted by the core network equipment are unique on the core network side.

[0040] When establishing the UE initialization context, the core network device should send the transport la...

Embodiment 3

[0080] refer to image 3 , shows a structural block diagram of an LTE base station in Embodiment 3 of the present invention.

[0081] The LTE base station of this embodiment includes: a receiving module 302, configured to receive the GPRS Tunneling Protocol packet transmitted by the core network service gateway; an acquisition module 304, configured to obtain the tunnel from the packet header of the GPRS Tunneling Protocol packet ID; the tunnel ID includes: S1 interface user ID, bearer ID, and tunnel type indication information, wherein, the S1 interface user ID is used to uniquely identify the user equipment of the S1 interface, the bearer ID is used to identify the bearer of the user equipment, and the tunnel type indication information is used for To indicate the type of the S1 interface tunnel; the selection module 306 is configured to select a bearer for data transmission according to the S1 interface user ID, bearer ID, and tunnel type indication information.

Abstract

The invention provides a method for selecting a bearer, and an LTE base station. The method for selecting the bearer comprises that: the LTE base station receives a general packet radio service tunnel protocol data packet transmitted by a core network service gateway; tunnel identification is acquired from a packet header of the general packet radio service tunnel protocol data packet; the tunnel identification comprises S1 interface user identification, bearer identification and tunnel type indication information, wherein the S1 interface user identification is used for uniquely identifying user equipment of an Si interface, the bearer identification is used for identifying the bearer of the user equipment, and the tunnel type indication information is used for indicating a tunnel type of the Si interface; and the bearer is selected to perform data transmission according to the S1 interface user identification, the bearer identification and the tunnel type indication information. Extra processing cost caused by user plane processing is avoided and data processing efficiency is enhanced simultaneously via the method for selecting the bearer.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for selecting a bearer and an LTE base station. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution) system, a base station communicates with a core network device through an S1 interface. The S1 interface is divided into two parts, the control plane and the user plane. Wherein, the control plane can be expressed as S1-MME (S1-Mobile Management Entity, the mobility management entity of the S1 interface), and the user plane can be expressed as S1U (S1User Plane, the user plane of the S1 interface). The control plane is responsible for the core network bearer service management and the establishment of the UE (User Equipment, user equipment) initial context, interacts through the S1-AP (S1Application Part) protocol, and assigns an identifier to each tunnel. The user plane interacts through the GTP-U (GPRS Tunneling Pro...
