Method for immediate access to a random access channel
First Claim
1. A method for transmitting a message comprising one or more preambles and a message body, said method comprising:
- determining whether it is allowed to transmit a first preamble of the message from a user equipment device to a network entity in an immediately available access time slot of a random access channel,transmitting the first preamble if the transmission is allowed, andtransmitting the message body if a positive acknowledgment to the preamble is received from the network entity on another channel.

Abstract
A method is provided for transmitting a message comprising one or more preambles and a message body from a user equipment device to a network entity. The method includes determining whether it is allowed to transmit a first preamble of the message to the network entity in an immediately available time slot of a random access channel, transmitting the first preamble if it is allowed, and transmitting the message body if a positive acknowledgement to the preamble is received from the network entity on another channel. The user equipment device may determine transmitting the preamble invariably, based on a persistence value or an indication received from the network entity, based on whether the device has not transmitted on the random access channel for longer than a predetermined, or based on whether the device has not transmitted on the random access channel for longer than a random time period.

18. A network entity for receiving a message comprising one or more preambles and a message body, said network entity comprising:
-
a processing device configured to set a parameter according to one or more conditions of the random access channel, a receiver for receiving from a user equipment device a first preamble of the message on a random access channel and for receiving the message body after an acknowledgement to the first preamble, and a transmitter for transmitting the parameter as a part of a system information broadcast, and transmitting to the user equipment device the acknowledgement of the first preamble on another channel, wherein the user equipment device is configured to determine whether it is allowed to transmit the first preamble in an immediately available access time slot of the random access channel based on the parameter. - View Dependent Claims (19)
