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.

First claim

The invention claimed is:

1. 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.

2. The method of claim 1 , wherein the initial ranging resource is configured as a resource except the handover resource within resources allocated to the mobile communication system.

3. 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.

4. The method of claim 3 ,
wherein the initial ranging resource is configured as a resource except the handover resource within the resources allocated to the mobile communication system.

5. 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.

6. The base station of claim 5 , wherein the initial ranging resource is configured as a resource except the handover resource within the resources allocated to the mobile communication system.

7. 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.

8. The terminal of claim 7 ,
wherein the initial ranging resource is configured as a resource except the handover resource within the resources allocated to the mobile communication system.

9. The method of claim 1 , wherein the initial ranging resource is allocated except the handover resource within resources allocated to the mobile communication system.

10. The method of claim 3 , wherein the initial ranging resource is allocated except the handover resource within resources allocated to the mobile communication system.

11. The base station of claim 5 , wherein the initial ranging resource is allocated except the handover resource within resources allocated to the mobile communication system.

12. The terminal of claim 7 , wherein the initial ranging resource is allocated except the handover resource within resources allocated to the mobile communication system.
