Embodiment Construction

[0022] With reference to the accompanying drawings, figure 1 Shown is a block diagram of an embodiment of a protocol stack device equipped with simultaneous processing of RRC blocks according to the present application.

[0023] Simultaneously Handling RRC (SH RRC) block 200 is a sublayer of UMTS protocol stack 100 radio interface layer 3 130 . The SH RRC 200 exists only in the control plane, and provides an information transfer service to the non-access stratum NAS 134 . The SH RRC 200 is responsible for controlling the configuration of the radio interface Layer 1 110 and Layer 2 120 . When the UTRAN wishes to change the UE configuration, it will issue a message to the UE containing an order to invoke a specific RRC procedure. The UE's SH RRC 200 layer decodes this message and starts the appropriate RRC procedure. Typically, when the procedure is completed (successfully or not), the SH RRC (via lower layers) sends a response message to UTRAN, informing UTRAN of the result...

Abstract

[0051] The details of an apparatus and method of handling simultaneous universal terrestrial radio access network radio resource control procedures which change the security configuration in a universal mobile telecommunications system user equipment are disclosed herein. According to one aspect of the present application, there is provided a user equipment apparatus having a message handler, a sequential processor, a command store, and a security configuration change detector, wherein said message handler is coupled to said command store, is coupled to said sequential processor, and is coupled to said security configuration change detector to save, process, and detect configuration changes in commands respectively, and to determine if there is an existing command at the user equipment, such that the user equipment appears to the UTRAN as though it were processing commands simultaneously. According to another aspect, there is provided a method of processing simultaneous commands at a user equipment having a security configuration, including the steps of: determining if there is an existing command at the user equipment; upon reception of a received command: suspending the existing command processing; determining if commands contain a security configuration change; and either rejecting the received command; or saving the received command prior to resuming the existing command; such that the user equipment appears to the UTRAN to be processing commands simultaneously.

Description

[0001] The present application relates to a device and a method for handling a simultaneous UTRAN radio resource control procedure for changing security configurations in a UMTS user equipment. technical field [0002] The present application relates generally to Universal Mobile Telecommunications System (UMTS), and more particularly to an apparatus and method for handling simultaneous UMTS radio resource control procedures. Background technique [0003] The Universal Mobile Telecommunications System (UMTS) is a third generation public land mobile telecommunications system. Various standardization bodies are known for promulgating and setting UMTS standards, each standardization body doing its best in its own field. For example, the 3rd Generation Partnership Project (3GPP) is known for promulgating and setting the Global System for Mobile Communications (GSM)-based UMTS standard, and the 3rd Generation Partnership Project 2 (3GPP2) is known for promulgating and setting the...
