Abstract

The present disclosure describes a bearer setup method and an apparatus. The method includes: transmitting, by a user equipment, a request message to a control node, where the request message is used to request setup of a transmission bearer for transmitting a data packet of a service between the user equipment and the control node, and the request message includes a parameter of the service; receiving, by the user equipment, a response message transmitted by the control node in response to the request message, where the response message includes configuration information of the transmission bearer; and setting up, by the user equipment, the transmission bearer with the control node according to the configuration information.

Claims

1. A terminal, comprising:

a transmitter, the transmitter configured to transmit a request message to a control node, wherein the request message is used to request setup of a transmission bearer for transmitting a data packet of a service between a user equipment and the control node, and the request message comprises a parameter of the service;

a receiver, the receiver configured to receive a response message transmitted by the control node in response to the request message, wherein the response message comprises configuration information of the transmission bearer; and

a processor, the processor configured to set up the transmission bearer with the control node according to the configuration information.

2. The terminal according to claim 1, wherein the parameter of the service that is added by the transmitter to the request message comprises at least one of:

a service type of the service, wherein the service type comprises at least one of an ultra-reliable service, a short delay service, a small-sized packet transmission service, a streaming service, or a conversational service;

a service feature of the service, wherein the service feature comprises at least one of a size of the data packet of the service, a transmission interval of the data packet, a delay requirement of the data packet, or a rate requirement of the data packet;

a quality of service (QoS) corresponding to the service;

a quality of service class identifier (QCI) parameter;

or

at least one of;

an address of a source server corresponding to the service, an address of a destination server corresponding to the service, or an access point name corresponding to the service.

13. The terminal according to claim 1, wherein the control node is an evolved Node B (eNB) or a radio network controller (RNC).

14. The terminal according to claim 1, wherein the request message is a radio resource control (RRC) connection setup request message.

3. A control node, comprising:

a receiver, the receiver configured to receive a request message transmitted by a user equipment, wherein the request message is used to request setup of a transmission bearer for transmitting a data packet of a service, and the request message comprises a parameter of the service; and

a processor, the processor configured to generate a response message according to the parameter of the service, wherein the response message comprises configuration information of the transmission bearer, and the configuration information is used to set up the transmission bearer between the control node and the user equipment.

4. The control node according to claim 3, wherein the parameter of the service that is obtained by the processor from the request message comprises:

a service type of the service, wherein the service type comprises at least one of an ultra-reliable service, a short delay service, a small-sized packet transmission service, a streaming service, or a conversational service;

a service feature of the service, wherein the service feature comprises at least one of a size of the data packet of the service, a transmission interval of the data packet, a delay requirement of the data packet, or a rate requirement of the data packet;

a quality of service (QoS) corresponding to the service;

a quality of service class identifier (QCI) parameter;

or

at least one of;

an address of a source server corresponding to the service, an address of a destination server corresponding to the service, or an access point name corresponding to the service.

5. The control node according to claim 3, wherein the control node further comprises:

a first transmitter, the first transmitter configured to transmit indication information to a second control node, wherein the indication information is used to indicate that the control node agrees to set up the transmission bearer with the user equipment.

6. The control node according to claim 3, wherein the control node further comprises:

a second transmitter, the second transmitter configured to transmit a transmission bearer setup request to a second control node, wherein the transmission bearer setup request is used to request setup of a data transmission channel between the control node and the second control node;

wherein the receiver is further configured to receive a feedback message of the second control node in response to the transmission bearer setup request, wherein the feedback message comprises an address of the data transmission channel on the second control node; and

wherein the processor is further configured to set up the data transmission channel with the second control node according to the address of the data transmission channel on the second control node.
