[0028] figure 2 The flowchart of the first embodiment of the method for solving the integrity protection problem in the dual-domain concurrent process of the present invention is shown. See figure 2 , the processes before the RRC (Radio Resource Control, radio resource control) module of the terminal receives the security mode command message from the network are all existing technologies, and will not be repeated here. When the RRC module of the terminal receives a security mode command message from the network to start the process of enabling integrity protection, it must first check whether there is a message that has been sent but has not been confirmed by the underlying RLC module before sending the security mode completion message.

Abstract

The invention discloses a method for solving an integrality protection problem in a double-domain concurrent process, which improves the reliable success rate in the signaling process and also can improve the success rate of services if the problem happens in a service establishing process. The invention adopts the technical scheme that the method comprises the following steps: when an RRC moduleof a terminal receives security mode command message sent by a network for requiring for starting the integrality protection process, checking whether uplink direct transmission data which is sent but not yet verified by the RRC module of the bottom layer exists before sending the security mode completion message; and if the uplink direct transmission data which is sent but not yet verified by the RRC module of the bottom layer exists, autonomously setting a condition by the terminal, and then sending the security mode completion message after meeting the condition to inform the network of starting the integrality process. The method is applied in the field of wireless communication.

Description

technical field [0001] The invention relates to a protection processing method in mobile communication, in particular to a processing method for solving integrity protection problems in a dual-domain concurrency process at a terminal. Background technique [0002] UE (User Equipment, terminal) often encounters the concurrent process of the two domains of circuit (CS) domain and packet (PS) domain during movement or use, such as the location update (LU) of entering a new location area ) and the routing area update (RAU) process concurrently or the circuit domain service and packet domain service establishment process concurrently. According to the description of the current protocol and the implementation of each network element device, the process of connecting the Iu interface to the circuit domain and the packet domain is carried out separately, which will lead to the occurrence of the security mode control process of one domain and the direct transmission process of anoth...
