Embodiment 1

[0058] This embodiment provides a control message transmission method on the base station side, which solves the problem that the control message transmission on the base station side is easy to be congested in the LTE system, such as figure 2 As shown, the method includes:

[0059] Step 201: The RLC receives the PDCP message sent by the PDCP layer, detects that the first bit of the PDCP message is a control message, and when the RLC SDU forms a PDU, the RLC creates an indication message of the control message, and the indication message It is used to indicate that the current message is a control message requiring emergency scheduling, and send the indication message together with the control message and other control messages to the MAC layer.

[0060] Wherein, the control message of the PDCP layer may include a PDCP status report and a ROCH feedback message; other control messages may include an RLC status report created by the RLC, and the like. Generally, the control pa...

Embodiment 2

[0074] This embodiment provides a method for transmitting control packets on the UE side to solve the problem of easy congestion in the transmission of control packets on the UE side in the LTE system, such as Figure 4 As shown, the method includes:

[0075] Step 401: The RLC receives the PDCP message sent by the PDCP layer, detects that the first bit of the PDCP message is a control message, and when the RLC SDU forms a PDU, the RLC creates an indication message of the control message, and the indication message It is used to indicate that the current message is a control message requiring emergency scheduling, and send the indication message together with the control message and other control messages to the MAC layer.

[0076] Wherein, the control message of the PDCP layer may include a PDCP status report and / or ROCH feedback message; other control messages may include an RLC status report created by the RLC, and the like. Generally, the control packets sent by the RLC in...

Abstract

The invention discloses a method for controlling message transmission. The method includes: when detecting that a control message needs to be sent, generating an indication message, and sending the indication message together with the control message to the medium Access control layer MAC, the indication message is used to indicate that the current message is a control message; MAC first detects which are control messages based on the indication message, and then calculates the control message and other data messages respectively The number of bytes, determine the bandwidth and send the bandwidth request to the scheduler; prioritize the scheduling of the control message. Correspondingly, the present invention also discloses the base station and the user equipment corresponding to the above control message transmission method, which solves the problems of control message loss and long transmission delay caused by link congestion.

Description

technical field [0001] The invention relates to communication technology, in particular to a control message transmission method and device. Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) network provides a full link service level (QoS, Quality of Service) guarantee mechanism. Specifically for the air interface, the scheduling priority is clearly indicated in the relevant protocol as an important parameter. The message packet of the wireless signaling bearer (SRB, Signaling Radio Bearer) is confirmed to be configured as the highest. At the same time, different scheduling priorities are configured for different service types, that is, different QoS scale values ​​(QCI, QoS Class Identifier). [0003] In the case of the current scheduling priority, if the guaranteed bit rate (GBR, Guranteed Bit Rate) business is full or about to be full (only a few bytes are left in each transmission time interval (TTI, Transmission Time Interval)) air inter...
