Embodiment Construction

[0027] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0028] figure 1 is a flowchart illustrating a general message processing method.

[0029] refer to figure 1 , UE (User Equipment) first receives a general message (S11) and performs an integrity check on it (S12). Depending on the result of the integrity check, the message is processed normally or discarded. That is, if the message passes the integrity check, it is processed normally (S13). If the message does not pass the integrity check, it will be discarded due to security issues (S14).

[0030] figure 2 is a flowchart illustrating a method of processing a security setting control message according to the first embodiment of the present invention.

[0031] refer to figure 2 , UE (User Equipmen...

Abstract

The invention discloses a method for processing security information in a radio resource control layer (RRC) of a mobile communication system. The processing method of this security information comprises the steps of: receiving security information (S31), storing previous security-related variables, performing an integrity check on the received security information (S34), discarding the security information according to the integrity check result (S37 ) or process security information (S36), and update security-related variables (S33). Therefore, the method for processing security setting control information provided here includes an integrity check of the received security information.

Description

technical field [0001] The present invention relates to a message processing method applied to mobile communication, and more specifically, relates to a method for processing safety messages in the RRC layer. Background technique [0002] The Universal Mobile Telecommunications System UMTS includes user equipment UE, UMTS terrestrial radio access network UTRAN and core network CN. Moreover, UTRAN includes multiple radio network subsystems RNS. Each RNS contains a radio network controller RNC and multiple Node Bs managed by the RNC. Node B receives uplink signals from UEs and transmits downlink signals to UEs. RNC is responsible for the allocation and management of radio resources and serves as an access point connecting Node B to CN. Each UE connected to UMTS is managed by a specific RNC in UTRAN, and this specific RNC is called SRNC (Serving RNC). [0003] The UTRAN configures, maintains and manages the Radio Access Bearer RAB for communication between UE and CN. The C...
