Abstract

The embodiment of the invention provides a random access method, terminal equipment and communication system. The method comprises the steps of determining the current traffic and a traffic threshold value; and determining a random access type according to the relation between the current traffic and the traffic threshold value. According to the method provided by the embodiment of the invention, the terminal equipment can select an appropriate random access type according to the current traffic and the like, thereby avoiding the waste of resources and the delay caused by the situation which is only limited to the type of public enhancement private channels or the type of random access channels, and improving the utilization efficiency of resources.

Description

[0001] This application claims the priority of the invention patent application 201110084143.1 entitled "Random Access Method, Terminal Equipment and Communication System" submitted to the State Intellectual Property Office on April 2, 2011. technical field [0002] The embodiments of the present invention relate to the field of wireless communication, and more specifically, to a random access method, a terminal device and a communication system. Background technique [0003] According to the current agreement, when both UE (User Equipment; User Equipment) and UTRAN (Terrestrial Radio Access Network; Terrestrial Radio Access Network) support Common E-DCH (Common Enhanced-Dedicated Channel; public enhanced dedicated channel), in Users in the non-dedicated connection state can only compete for Common E-DCH resources to send subsequent data regardless of the size of the service data packet to be sent. [0004] With idle (idle), CELL_FACH (CELL Forward Access Channel; cell forwa...
