Device and method for rebuilding connection in mobile communication system environment

Abstract

The present invention provides a device and method using the radio resource control protocol (RRC protocol) in a mobile communication system environment the reconstruction of the connection. In an embodiment, a user terminal equipment (User Equipment) is provided, when the state of the user terminal equipment is a connection status connected to a mobile communications system, the reconstruction operation of the connection is performed. When problems occur in the network, a Security Mode is activated, and the user terminal equipment will start the reconstruction connection program of the RRC protocol. However, when the security mode is not activated and the RRC protocol represents that it has reached the maximum retransfer attempting number, the user terminal device will reset the lower layer of the radio resource control protocol, release unnecessary radio resource, and indicate the released RRC protocol connection to the upper layer of the RRC protocol; and then enters a radio resource control protocol idle status (RRC_IDLE State), and waits for the next trigger event.

Description

technical field [0001] The present invention relates to a program for reestablishing a connection, in particular to a device and method for reestablishing a connection using a radio resource control protocol in a wireless network system environment. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third-generation mobile telecommunications system evolved from the Global System for Mobile Communications (GSM). UMTS is a European standard, and its main purpose is to provide better mobile communication services based on the GSM core network and Wideband Code Division Multiple Access (W-CDMA) technology. Although UMTS can provide high data transfer rates, wireless data usage is bound to increase significantly in the next few years. Therefore, the long-term evolution technology of the universal mobile communication system is proposed, and its purpose is to further improve the universal mobile communication system to achieve the goal of hig...

Problems solved by technology

Therefore, when the radio link control protocol indicates that the number of retransmission attempts has reached the maximum, the security mode of the radio resource control protocol may not be enabled, so that Yu and the user terminal equipment can only use the radio resource control protocol when the security mode is enabled. The prerequisite for reestablishing the connection procedure of the radio resource control protocol is contradictory, and may also cause errors in the operation of the user terminal equipment
