METHODS FOR PROVIDING ACCESS TO WIRELESS RESOURCES IN A TRUNKED RADIO COMMUNICATION SYSTEM

摘要

Methods are disclosed for providing requested access, network-initiated acce ss and autonomous access to communication resources (101-105) by wireless unit( s) (112, 114), and for controlling the different types of access using access control identifier(s) assigned to the devices. Requested access requires a unit to send a call request (302) to a resource controller (106). The request (302) includes an identification of the unit and an identifier associated with the unit. Netwo rk- initiated access comprises a resource controller or other fixed network equipment sending a page request (502) to the unit which responds with a page response message (504) including the identification of the unit and an identifier. The resource controller (106) determines, based on the identifier. whether a communication resource is available to support the request. Autonomous access comprises the unit (112, 114) receivi ng an advertisement message (402) identifying a communication resource and one or more identifiers associated with the communication resource. The unit determines its eligibility for autonomous access based an the advertisement message.
