Problems solved by technology

But there are following problems in this scheme: 1, need to increase the sorting function to data packet in PDCP agreement, this way confuses the functional division of RLC and PDCP, has destroyed the principle that only RLC is responsible for data packet sorting; 2, needs in A complete set of sequential sending and receiving reordering mechanisms are added to the PDCP protocol, which greatly changes the PDCP protocol stack; 3. In the current protocol, PDCP does not need to process transparent mode (TM) data. If PDCP supports data packets After the sorting function, in order to complete the function of the protocol, it is necessary to increase the processing of the TM mode
4. When PDCP sorts through the SN numbers of PDCP PDUs, it is possible to sort PDCP PDUs sent by multiple RLCs, resulting in high complexity and prolonged sorting; 5. When the receiver reestablishes (reestablishment), because RLC and The non-ideal transmission time of data and control information between PDCP is too long, causing a new delay in the re-establishment process

Embodiment 1

[0019] An embodiment of the present invention provides an information processing method, such as figure 1 shown, including:

[0020] Step 101: In the frame structure of the data protocol unit PDU of the radio link sublayer RLC unacknowledged mode UM, add a super sequence number and an end identification bit; wherein, the super sequence number is used to indicate the PDU group where the PDU is located Group identification information; the end identification bit is used to indicate whether the PDU is the last PDU in the PDU group;

[0021] Step 102: Send the PDU of the RLC UM added with the super sequence number and the end identification bit to the receiving end.

[0022] The solution provided in this embodiment aims at the requirement of simplifying RLC service data unit (SDU) sorting under 5G network, and redesigns the frame structure of traditional RLC UMD PDU to obtain a new RLC UMD PDU frame structure, so that the redesigned RLC UMD PDU is applicable to both The need to ...

Embodiment 2

[0035] Combined with the technical solution provided in Embodiment 1, multiple examples are provided in this embodiment to illustrate the processing method in the actual frame structure:

[0036] combine Figure 2a and Figure 2b Introduce the frame structure of the traditional RLC UMD PDU and the frame structure of the scheme provided by this embodiment respectively, in Figure 2a On the basis of the provided traditional RLC UMD PDU structure (5bitSN) without LI, add the RLC UM frame structure of HSN domain and EM domain (HSN takes 7bir length as an example), and get Figure 2b frame structure. This embodiment can be applied at the sending end, and the centralized control module distributes the PDU clusters, and each PDU cluster is processed and mapped into a group of RLC PDUs. Multiple sets of parallel RLC PDUs are sent to the receiving end, and the receiving end RLC first determines the end position of the current PDU cluster according to the EM field, then sorts all the...

Embodiment 3

[0040] An embodiment of the present invention provides an information processing device, such as Figure 8 As shown, the device includes:

[0041] The information processing unit 81 is configured to add a super sequence number and an end identification bit in the frame structure of the protocol data unit PDU of the radio link control RLC unacknowledged mode UM; wherein the super sequence number is used to indicate where the PDU is located The identification information of the PDU group; the end identification bit is used to indicate whether the PDU is the last PDU in the PDU group;

[0042] The communication unit 82 is configured to send the PDU of the RLC UM added with the super sequence number and the end identification bit to the receiving end.

[0043] The solution provided in this embodiment aims at the requirement of simplifying RLC service data unit (SDU) sorting under 5G network, and redesigns the frame structure of traditional RLC UMD PDU to obtain a new RLC UMD PDU ...

Abstract

The present invention discloses an information processing method and device. The method comprises: in the frame structure of the data protocol unit PDU of a unacknowledged mode (UM) of a wireless link sublayer RLC, adding a super serial number and an ending identification bit, wherein the super serial number is configured to indicate the identification information of a PDU group where the PDU is located; the ending identification bit is configured to indicate whether the PDU is the last PDU in the PDU group or not; and sending the PDU of the RLC UM adding the super serial number and the ending identification bit to a receiving terminal.

Description

technical field [0001] The invention relates to transmission management technology in the field of communication, in particular to an information processing method and device. Background technique [0002] In the prior art, PDCP / RLC is split and reconfigured, and the PDCP PDU reordering function is added to the PDCP protocol function, while the RLC function remains unchanged. But there are following problems in this scheme: 1, need to increase the sorting function to data packet in PDCP agreement, this way confuses the functional division of RLC and PDCP, has destroyed the principle that only RLC is responsible for data packet sorting; 2, needs in A complete set of sequential sending and receiving reordering mechanisms are added to the PDCP protocol, which greatly changes the PDCP protocol stack; 3. In the current protocol, PDCP does not need to process transparent mode (TM) data. If PDCP supports data packets After the sorting function, in order to complete the protocol fu...
