Embodiment 1

[0149] see Figure 5 , the figure shows a data transmission channel processing method, which can be applied to Figure 4 The source base station in , the specific steps are as follows:

[0150] Step 501, the source base station sends a handover request message to the target base station, and the handover request message includes a PDU flow-based data forwarding indication or an RB-based data forwarding indication;

[0151] Step 502, the source base station receives the handover request response message sent by the target base station, and the handover request response message includes data forwarding tunnel address information;

[0152] Among them, the address information of the data forwarding tunnel is the address information assigned by the target base station to the corresponding PDU flow according to the data forwarding indication based on the PDU flow and the QoS admission data of the target base station (or called the QoS admission status of the target base station); o...

Embodiment 2

[0159] see Figure 6 , the figure shows a data transmission channel processing method, which can be applied to Figure 4 The target base station in , the specific steps include:

[0160] Step 601, the target base station receives a handover request message sent by the source base station, and the handover request message includes a PDUflow-based data forwarding indication or an RB-based data forwarding indication;

[0161] Step 602, the target base station allocates data forwarding tunnel address information for the corresponding PDU flow according to the data forwarding indication based on the PDU flow and the QoS acceptance data of the target base station; or the data forwarding tunnel address information is determined by the target base station according to the RB-based data forwarding indication and The QoS acceptance data of the target base station assigns data forward tunnel address information to the corresponding RB;

[0162] Step 603, the target base station sends a...

Embodiment 3

[0180] see Figure 7 , the figure shows a data transmission channel processing method, which can be applied to Figure 4 In the core network control plane function entity CN-C, the specific steps are as follows:

[0181] Step 701, the core network control plane functional entity sends a handover request message to the target base station, where the handover request message includes a PDU flow-based data forwarding indication or an RB-based data forwarding indication;

[0182] Step 702, the core network control plane functional entity sends a handover command to the source base station, and the handover command includes a data forwarding tunnel address;

[0183] Wherein, the data forwarding tunnel address information is the address information assigned by the target base station to the corresponding PDU flow according to the PDU flow-based data forwarding indication and the QoS admission data of the target base station; or the data forwarding tunnel address information is The...

Abstract

The embodiment of the invention provides a processing method of a data transmission channel and devices. The processing method comprises the steps that a target base station receives a switching request message sent by a source base station, wherein the switching request message comprises a PDU flow based data forward-transmission instruction or a RB based data forward-transmission instruction; the target base station distributes data forward-transmission tunnel address information to a corresponding PDU flow based on the PDU flow based data forward-transmission instruction and the QoS reception data of the target base station or distributes the data forward-transmission tunnel address information to a corresponding RB based on the RB based data forward-transmission instruction and the QoSreception data of the target base station; and the target base station sends a switching request response message to the source base station, wherein the switching request response message includes the data forward-transmission tunnel address information.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a processing method and equipment for a data transmission channel. Background technique [0002] see figure 1 , the figure shows the bearer model in the existing LTE (Long Term Evolution, long-term evolution) system, the core network in the existing LTE system is responsible for generating the QoS parameters of E-RAB (Evolved Radio Access Bearer, evolved radio access bearer) , because the air interface RB (Radio Bearer, radio bearer) and the E-RAB have a one-to-one mapping relationship, so the QoS parameters of the air interface RB directly use the E-RAB QoS parameters generated by the core network. [0003] The heterogeneous access technology in the mobile communication network leads to the need to support multiple tunneling protocols in the core network to support mobility and ensure QoS, such as GTP (GPRS Tunneling Protocol, GPRS tunneling protocol), PMIP and s...
