Embodiment Construction

[0034] The communication process generally starts with random access. The random access request is generally initiated by the upper layer of the user terminal and executed by the lower layer, such as initiated by the circuit domain mobility management (MM, Mobility Management) layer, which sends a connection establishment request to the radio resources (RR, Radio Resources) layer, and then by The RR sends a channel request to the network to establish a random access channel. The RR will also initiate a random access request. For example, after receiving a notification from the network, a paging message, or detecting a change in a received location code message, the RR can initiate a paging response, a notification response process, or a location update process (including random access channel establishment process).

Abstract

This invention discloses a method for setting up random access channels and UE, in which, the method includes: a user terminal judges kind of random accessed service before sending a random access channel request, it tansmits channel request directly if it is initiated by a circuit domain terminal, otherwise, it sends it after a period of time, after receiving the request, the network controls setting up channels based on the network situation, in which, the radio resource module of the user terminal includes a service test module used in testing randomly accessed service kind, if it is the service sponsored by the circuit domain terminal, it transmits the channel required information to the network immediately, otherwise, it waits for a period of time randomly and sends the request to the network.

Description

technical field [0001] The present invention relates to a cluster wireless communication system, more specifically, the present invention relates to a method for establishing a random access channel in a cluster wireless communication system and a user terminal. Background technique [0002] The trunking wireless communication system is a communication system that can conduct command and dispatch economically and flexibly. In recent years, it has been widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire protection, police, water conservancy, military and other units to meet the needs of internal communication of each unit. [0003] In the current trunking wireless communication system, each group includes a group identification ID and a group call area, wherein the group call area is defined as a group of cells. When a group call is initiated, a group of users in a specific area can simultaneously join the gro...
