Abstract
A method and apparatus for using dedicated signatures for an initial access procedure is provided for different cases in order to prevent contention due to several users sending the same signature. The present invention is applicable to a RACH initial access procedure performed when synchronizing uplink timing either periodically or upon reception of downlink data or when performing handover.
Claims24
A method of establishing a communication link between a mobile terminal and a network, the method comprising:
- receiving an indication of a dedicated signature for accessing the network;
- receiving an indication of a cell-specific mobile terminal identifier;
- requesting access to the network using the dedicated signature;
- and
- receiving a response acknowledging receipt of the access request and comprising resources for accessing the network, the response addressed using the cell-specific mobile terminal identifier.
A method of establishing a communication link between a mobile terminal and a network, the method comprising:
- providing an indication of a dedicated signature for accessing the network and a cell-specific mobile terminal identifier;
- receiving a request for access to the network using the dedicated signature;
- and
- transmitting a response acknowledging receipt of the access request and comprising resources for accessing the network, the response addressed using the cell-specific mobile terminal identifier.
A mobile terminal for of establishing a communication link with a network, the mobile terminal comprising:
- a transmitting/receiving unit transmitting and receiving messages between the mobile terminal and the network;
- a display unit displaying user interface information;
- an input unit receiving inputs from a user;
- and
- a processing unit processing an indication of a dedicated signature for accessing the network and an indication of a cell-specific mobile terminal identifier, controlling the transmitting/receiving unit to request access to the network using the dedicated signature, and processing a response received from the network and addressed using the cell-specific mobile terminal identifier,
- wherein the response acknowledges receipt of the access request and comprises resources for accessing the network.
A network for establishing a communication link with a mobile terminal, the network comprising:
- a transmitter transmitting messages to the mobile terminal;
- a receiver receiving messages from the mobile terminal;
- and
- a controller controlling the transmitter to provide an indication of a dedicated signature for accessing the network and a cell-specific mobile terminal identifier, processing a request for access to the network using the dedicated signature, and controlling the transmitter to transmit a response addressed using the cell-specific mobile terminal identifier,
- wherein the response acknowledges receipt of the access request and comprises resources for accessing the network.
