Mobile communication device, system and connection setup method

Abstract

The invention provides a mobile communication device, a mobile communication system and a connection setup method. The mobile communication device is provided with a wireless module and a controller module, wherein the wireless module is used for executing wireless transmission and wireless reception between the mobile communication device and a service network; the controller module is used for transmitting connection request information to the service network through the wireless module and receiving connection rejection information corresponding to the connection request information from the service network in a downlink shared channel through the wireless module; and the controller module also further determines whether the connection rejection information indicates that the downlink shared channel is congested or not, and retransmits the connection request information through the wireless module and waits for receiving the subsequent response information from the service network in a forward access channel if the connection rejection information indicates that the downlink shared channel is congested.

Description

technical field [0001] The present invention mainly relates to wireless communication technology, in particular to a connection establishment method for efficiently using wireless resources. Background technique [0002] The Universal Mobile Telecommunications System (UMTS), one of the third-generation mobile communication technologies, evolved from the Global System for Mobile communications (GSM), which mainly utilizes the core network of the Global System for Mobile Communications and The new Wideband Code Division Multiple Access (WCDMA) technology provides users with higher wireless transmission rate and better mobile communication services. Generally speaking, in a universal mobile telecommunication system, a mobile communication device (or called User Equipment (UE)) must first perform a connection establishment procedure before obtaining mobile communication services from a service network. [0003] According to the 3rd Generation Partnership Project (3rd Generation...

Problems solved by technology

However, according to the 7th edition of the UMTS specification standard, the connection rejection information of the RRC will not indicate whether the congestion occurs on the downlink shared channel, the dedicated channel, or both. In this way, the user The device can only perform a limited number of retransmissions, that is, retransmits the RRC connection request information until it receives the RRC connection establishment information or reaches the retransmission limit
