System and method for using resources in a communication system

A method for using resources in a communication system, comprising the steps of:nif a user terminal moves from a first region to a second region, controlling the user terminal to use a resource of a first communication node which provides a service to the first region during a first predetermined time duration;allocating a resource of a second communication node which provides a service to the second region to the user terminal after the first predetermined time duration has expired;if the user terminal moves from the second region to the first region before the first predetermined time duration is expired, controlling the user terminal to use the resource of the first communication node during a second predetermined time duration, and controlling the user terminal to use the resource of the first communication node after the second predetermined time duration has expired; andif the user terminal moves from the second region to a third region before the first predetermined time duration is expired, controlling the user terminal to use the resource of the first communication node during the second predetermined time duration, and allocating a resource of a third communication node which provides service to the third region to the user terminal after the second predetermined time duration has expired.

An apparatus for using resources in a communication system, comprising:na processor, wherein:nif a user terminal moves from a first region to a second region, the processorncontrols the user terminal to use a resource of a first communication node which provides a service to the first region during a first predetermined time duration, and allocates a resource of a second communication node which provides a service to the second region to the user terminal after the first predetermined time duration has been expired,if the user terminal moves from the second region to the first region before the first predetermined time duration is expired, the processorncontrols the user terminal to use the resource of the first communication node during a second predetermined time duration, and controls the user terminal to use the resource of the first communication node after the second predetermined time duration has been expired, andif the user terminal moves from the second region to a third region before the first predetermined time duration is expired, the processorncontrols the user terminal to use the resource of the first communication node during the second predetermined time duration, and allocates a resource of a third communication node configured to provide service to the third region to the user terminal after the second predetermined time duration has expired.

A method for using resources in a communication system, comprising the step of:nif a user terminal to which a first region resource is allocated moves from a first region to a second region, performing at least one of;an operation of returning the first region resource and allocating a second region resource to the user terminal,an operation of maintaining the first region resource allocation for the user terminal,an operation of changing use of the first region resource for use in the second region and allocating the first region resource of which the use is changed for use in the second region to the user terminal,an operation of returning the first region resource, changing use of another first region resource for use in the second region, and allocating the another first region resource of which the use is changed for use in the second region to the user terminal,an operation of returning the first region resource, changing use of a third region resource for use in the second region, and allocating the third region resource of which the use is changed for use in the second region to the user terminal, andan operation of returning the first region resource, changing use of a resource which is not assigned to any of regions for use in the second region, and allocating the resource of which the use is changed for use in the second region to the user terminal.

An apparatus for using resources in a communication system, the apparatus comprising:nif a user terminal to which a first region resource is allocated moves from a first region to a second region, a processor for performing at least one of;an operation of returning the first region resource and allocating a second region resource to the user terminal,an operation of maintaining the first region resource allocation for the user terminal,an operation of changing use of the first region resource for use in the second region and allocating the first region resource of which the use is changed for use in the second region to the user terminal,an operation of returning the first region resource, changing use of another first region resource for use in the second region, and allocating the another first region resource of which the use is changed for use in the second region to the user terminal,an operation of returning the first region which resource, changing use of a third region resource for use in the second region, and allocating the third region resource of which the use is changed for use in the second region to the user terminal, andan operation of returning the first region resource, changing for use a resource which is not assigned to any of regions for use in the second region, and allocating the resource of which the use is changed for use in the second region to the user terminal.
