[0045] The first embodiment of the present invention provides a method for uploading buffer status. Here, the UE can be used to upload data to the network side. Before uploading data to the network side, the UE needs to send a BSR to the network side; here, the network side includes but does not Limited to eNBs.

[0046] figure 1 It is a flowchart of an embodiment of the method for uploading buffer state in the present invention, such as figure 1 As shown, the process includes:

[0047] Step 100: When data needs to be uploaded to the network side, acquire the wireless channel quality parameters of the UE and the data volume of the data to be uploaded to the network side.

[0048]In this step, the type of data uploaded to the network side is not limited. For example, the data uploaded by the network side includes but is not limited to: signaling packets, service packets, etc. Here, the signaling packet can be a Session Initiation Protocol (Session InitiationProtocol, SIP) me...

[0072] The second embodiment of the present invention provides a method for receiving buffer status. Here, the network side can receive the BSR uploaded by the UE, and allocate uplink authorization information for the UE based on the received BSR; the network side includes but is not limited to eNB.

[0073] figure 2 It is a flow chart of an embodiment of the method for receiving buffer state in the present invention, such as figure 2 As shown, the process includes:

[0074] Step 200: Receive an updated BSR sent by the UE, where the updated BSR is: a BSR updated based on the UE's radio channel quality parameters and the amount of data to be uploaded by the UE to the network side.

[0075] Before this step, when the UE needs to upload data to the network side, obtain the wireless channel quality parameters of the UE and the data volume of the data to be uploaded to the network side, and the acquired data volume to be uploaded to the network side is greater than the preset W...

[0083] Aiming at the method for uploading the buffer state in the first embodiment of the present invention, the third embodiment of the present invention provides a device for uploading the buffer state.

[0084] image 3 It is a schematic diagram of the composition and structure of the device for uploading the buffer state in the embodiment of the present invention, such as image 3 As shown, the device includes: an acquisition module 300, an update module 301 and an upload module 302; wherein,

[0085] The obtaining module 300 is configured to obtain the wireless channel quality parameter of the UE and the data volume of the data to be uploaded to the network side when data needs to be uploaded to the network side.

[0086] The update module 301 is configured to update the BSR based on the acquired wireless channel quality parameters of the UE and the data volume of data to be uploaded to the network side.

[0087] The upload module 302 is configured to upload the updated...

Abstract

The embodiment of the present invention discloses a method for uploading buffer state, including: when data needs to be uploaded to the network side, acquiring the wireless channel quality parameters of the user terminal (UE) and the data volume of the data to be uploaded to the network side; The acquired wireless channel quality parameters of the UE and the amount of data to be uploaded to the network side are used to update a buffer status report (BSR); and the updated BSR is uploaded to the network side. The embodiment of the invention also discloses a method for receiving the buffer state, a device for uploading the buffer state and a device for receiving the buffer state.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a method and device for uploading and receiving buffer state. Background technique [0002] Currently, when a user terminal (User Equipment, UE) requests an uplink resource from an evolved base station (Evolved Node B, eNB) through an uplink scheduling request (SchedulingRequest, SR), it only indicates whether the UE has uplink data to send, without specifying How much uplink data the UE needs to send; at this time, the UE needs to send a buffer status report (Buffer Status Report, BSR) to the eNB to let the eNB know the amount of uplink data that the UE needs to send, so that the eNB can decide how much uplink data to allocate to the UE resource. [0003] In the prior art, the UE writes the actual amount of data to be transmitted into the BSR, so as to request the eNB to schedule corresponding resources for the UE. When the UE is in a weak coverage area and needs to upload a lar...
