Problems solved by technology

[0005] After the encryption function is moved up, the ARQ block or the virtual MAC SDU is already encrypted data. If there is no special decryption process, the MS will not be able to decrypt this part of the data, resulting in data loss during the handover process.
In addition, currently 802.16e only considers downlink processing and does not consider uplink processing.
In the 802.16m system, because the uplink direction needs to support various high-speed services, the MS continues to send data packets according to its current sending status, which will cause a large amount of data to be sent repeatedly, wasting air interface resources
[0006] Therefore, the disadvantages of the prior art are: after the encryption function is moved up, in the 802.16m system, data loss is likely to occur during the handover process, and the MS repeatedly sends data packets according to its current sending state, which easily causes a large amount of data repetition Sending, wasting air interface resources

Embodiment Construction

[0020] The embodiment of the present invention provides a data processing method. Through the embodiment of the present invention, the sending end device sends the receiving state information of the CS SDU to the receiving end device, so that the receiving end device knows the sending of the receiving state information of the CS SDU The CS SDU reception status of the end device can avoid data loss during the handover process, and the processing is simple, saving air interface resources.

[0021] like figure 2 As shown, it is a flow chart of the method for data processing in the embodiment of the present invention, which specifically includes the following steps:

[0022] In step S201, the receiving end device receives the receiving state information of the CS SDU sent by the sending end device. The reception status information of the CS SDU includes: the sequence number of the first CS SDU that was not successfully received; or, the sequence number of the last CS SDU that wa...

Abstract

The embodiment of the invention discloses a data processing method. The method comprises the following steps: a receiving terminal device receives accepting state information of a convergence sublayer service data unit (CS SDU) sent by a sending terminal device; and the receiving terminal device sends the CS SDU to the sending terminal device according to the accepting state information of the CS SDU. By the method, the sending terminal device sends the CS SDU to the sending terminal device to cause the receiving terminal device to know the accepting state of the sending terminal device for the CS SDU, and to carries out the corresponding processing, thus avoiding the data loss during the switching process, and avoiding repeated transmission of a great amount of CS SDU, which saves the air interface resources.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a data processing method, system and device. Background technique [0002] According to the requirements of IMT-Advanced (International Mobile Telecommunication-Advanced, Advanced International Mobile Communication), IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) is currently developing a new wireless standard—IEEE 802.16m. In December 2006, IEEE formally established the 802.16m working group. The main purpose of this working group is to develop the fourth-generation mobile communication technology for IMT-Advanced on the basis of 802.16e. The current protocol model of IEEE802.16e is as follows: figure 1 shown. [0003] Now, in the research of 802.16m, someone proposes to move the SS (Security Sublayer, encryption sublayer) of user plane data to the MAC (Medium Access Control, media access contro...
