Embodiment Construction

[0030] The technical scheme of the method of the present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0031] In the method for fast access in the high-speed packet data system of the present invention, the rate of accessing the channel has nothing to do with the length of the load, and the length of the access test packet is shortened to take the time slot as the unit. The fast access method of the present invention specifically includes the following steps:

[0032] In the first step, the system informs the terminal through an overhead message that the system supports enhanced access channels;

[0033] In the second step, the terminal obtains the number of access prefix slots of the enhanced access channel through the access parameter overhead message;

[0034] In the third step, the terminal determines the length of the prefix when sending the access message test; preferably, the length of the access prefix c...

Abstract

The method comprises: the system informs the terminal that the system supports enhance access channel through overhead message; said terminal gets the time slot numbers of access preamble of the enhance access channel through access parameter overhead message; said terminal determines the length of the preamble of sending access message probe and determines the access channel rate of sending access channel probe; according to the load length to be transmitted and the access channel rate, the terminal determines the length of probe packet, and shortens the length of access packet; said terminal sends the access probe, which comprises the probe preamble and the access probe packet.

Description

technical field [0001] The present invention relates to an access method of a digital mobile communication system, in particular to a cellular system based on CDMA (Code Division Multiple Access) 2000 high-speed packet data HRPD (High Rate Packet Data, hereinafter referred to as HRPD) A quick access method for a mobile communication system or a trunking system. Background technique [0002] In existing wireless communication technologies, a terminal and a system perform information interaction through an air wireless interface, as shown in FIG. 1 . When the terminal needs the system to serve it, it must first apply for a communication channel, and this process is called the access process. In the relevant prior art field, the following are the technical concepts involved in the method of the present invention: [0003] Random access process: before the terminal establishes a business connection with the system and obtains services, it first sends some information necessary...
