Abstract
Provided is an INitial ranging (IN) method for a Machine to Machine communication service in a mobile communication system. The IN method includes if the presence of a terminal attempting IN is recognized, determining whether a service the terminal wants to receive is a mobile communication service or a Machine to Machine communication service; and setting an indicator indicating to use Ranging Preamble (RP) code partition information for available in the determined service, and transmitting ‘IN-related control information for mobile communication’ including the indicator to the terminal.
Claims12
An initial ranging method for a machine to machine communication service by a base station in a mobile communication system, the method comprising:
- detecting initial ranging of a terminal for the machine to machine communication service;
- generating resource information allocated for the initial ranging, the resource information comprising an indicator indicating whether to use a first resource configuration for a mobile communication or a second resource configuration for a machine to machine communication, and a start value of indexes of resource partition configurations in the second resource configuration, each of the first resource configuration and the second resource configuration comprising a plurality of resource partition configurations between an initial ranging resource and a handover resource with consecutive indexes;
- and
- transmitting, to the terminal, the resource information.
An initial ranging method by a terminal for a machine to machine communication service in a mobile communication system, the method comprising:
- transmitting, to a base station, a request of the initial ranging for the machine to machine communication service;
- receiving, from the base station, resource information allocated for the initial ranging, the resource information comprising an indicator indicating whether to use a first resource configuration for a mobile communication or a second resource configuration for a machine to machine communication, and a start value of indexes of resource partition configurations in the second resource configuration, each of the first resource configuration and the second resource configuration comprising a plurality of resource partition configurations between an initial ranging resource and a handover resource with consecutive indexes;
- identifying the indicator from the resource information;
- selecting a resource for the initial ranging based on the indicator and the start value;
- and
- performing the initial ranging with the base station using the selected resource.
A base station for performing initial ranging for a machine to machine communication service by a base station in a mobile communication system, the base station comprising:
- a controller configured to:
- detect initial ranging of a terminal for the machine to machine communication service, and
- generate resource information allocated for the initial ranging, the resource information comprising an indicator indicating whether to use a first resource configuration for a mobile communication or a second resource configuration for a machine to machine communication, and a start value of indexes of resource partition configurations in the second resource configuration, each of the first resource configuration and the second resource configuration comprising a plurality of resource partition configurations between an initial ranging resource and a handover resource with consecutive indexes;
- and
- a transceiver configured to transmit, to the terminal, the resource information.
A terminal for performing initial ranging for a machine to machine communication service in a mobile communication system, the terminal comprising:
- a transmitter configured to transmit a request of the initial ranging for the machine to machine communication service to a base station;
- a receiver configured to receive, from the base station, resource information allocated for the initial ranging, the resource information comprising an indicator indicating whether to use a first resource configuration for a mobile communication or a second resource configuration for a machine to machine communication, and a start value of indexes of resource partition configurations in the second resource configuration, each of the first resource configuration and the second resource configuration comprising a plurality of resource partition configurations between an initial ranging resource and a handover resource with consecutive indexes;
- and
- a controller configured to:
- identify the indicator from the resource information,
- select a resource for the initial ranging based on the indicator and the start value, and
- perform the initial ranging with the base station using the selected resource.
