Control method for uplink connecting of idle terminal
First Claim
1. A method for performing a random access procedure by a user equipment (UE) in an idle-mode which desires to receive a specific broadcast/multicast service in a wireless communication system, the method comprising the steps of:
- receiving a first message from a network, the first message including a counting request for the broadcast/multicast service;
in response to the first message, transmitting a preamble for a random access to the network;
in response to the preamble, receiving a second message including uplink (UL) radio resource allocation information from the network, the second message further including timing adjustment information and a connection indicator;
in response to the second message, transmitting a third message to the network using the uplink (UL) radio resource allocation information, the third message including a service identifier for the specific broadcast/multicast service; and
in response to the third message, receiving a contention resolution message from the network,wherein, when the connection indicator indicates that a connection to the network is required, the third message includes both a response to the counting request and a Radio Resource Control (RRC) connection request message, andwherein, when the connection indicator indicates that a connection to the network is not required, the third message includes the response to the counting request without the Radio Resource Control (RRC) connection request message.

Abstract
A method for controlling an uplink connection of an idle UE in a wireless communication system is disclosed. In a method for performing a random access procedure by an idle-mode user equipment (UE) which desires to receive a specific broadcast/multicast service in a wireless communication system, the method includes, receiving a first message transmitted from a network, so as to count the number of UEs which desire to receive the broadcast/multicast service, transmitting a preamble for a random access to the network, receiving a second message including uplink (UL) radio resource allocation information from the network in response to the preamble, transmitting a third message selected according to a connection indication information contained in the first or second message to the network using the uplink (UL) radio resource allocation information, wherein the connection indication information indicates whether a connection to the network is required or not, and receiving a contention resolution message from the network.

11. A method for counting the number of UEs in an idle-mode which desire to receive a specific broadcast/multicast service in a network of a wireless communication system, the method comprising the steps of:
-
transmitting a first message to a user equipment (UE), the first message including a counting request for the broadcast/multicast service in response to the first message, receiving a random access preamble from a specific UE; in response to the random access preamble, transmitting a second message including uplink (UL) radio resource allocation information, the second message further including timing adjustment information and a connection indicator; in response to the second message, receiving a third message from the UE using the uplink (UL) radio resource allocation information, the third message including a service identifier for the specific broadcast/multicast service; and in response to the third message, transmitting a contention resolution message to the UE, wherein, when the connection indicator indicates that a connection to the network is required, the third message includes both a response to the counting request and a Radio Resource Control(RRC) connection request message, and wherein, when the connection indicator indicates that a connection to the network is not required, the third message includes the response to the counting request without the Radio Resource Control (RRC) connection request message. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
