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...
