Abstract
A tunneling control method and apparatus for a coordinated multi-point transmission, and a method of transmitting data, are provided. The tunneling control method and the data transmission method may minimize a time delay that occurs because of the coordinated multi-point transmission between base stations.
Claims15
A tunneling control method for data transmission between base stations, the method comprising:
- reserving an estimated range of resources that are to be used to transmit data for a coordinated multi-point transmission between the base stations;
- and
- in response to receiving a request for a data rate that exceeds an average value of the estimated range:
- controlling a data transmission process using the reserved resources;
- and
- utilizing residual resources that are allocated to one or more other data transmission sessions such that the total amount of used resources is within a maximum value of the estimated range.
A method for a coordinated multi-point transmission between base stations, the method comprising:
- reserving an estimated range of resources that are to be used to transmit data for the coordinated multi-point transmission between the base stations;
- controlling setup signaling for the coordinated multi-point transmission between the base stations;
- in response to receiving a request for a data rate that exceeds an average value of the estimated range:
- controlling a data transmission process using the reserved resources;
- and
- utilizing residual resources that are allocated to one or more other data transmission sessions such that the total amount of used resources is within a maximum value of the estimated range;
- performing the coordinated multi-point transmission between the base stations using the reserved resources and/or the residual resources;
- controlling release signaling for the coordinated multi-point transmission between the base stations;
- and
- releasing the reserved resources.
A method for a coordinated multi-point transmission between base stations, the method comprising:
- establishing a legacy tunnel for the coordinated multi-point transmission between the base stations;
- reserving an estimated range of resources that are to be used to transmit data;
- controlling setup signaling for the coordinated multi-point transmission between the base stations;
- transmitting and receiving first data via the legacy tunnel;
- in response to receiving a request for a data rate that exceeds an average value of the estimated range, controlling a data transmission process to utilize residual resources allocated to one or more other data transmission sessions such that the total amount of used resources is within a maximum value of the estimated range;
- transmitting and receiving second data between the base stations using the reserved resources and/or the residual resources;
- controlling release signaling for the coordinated multi-point transmission between the base stations;
- releasing the reserved resources;
- and
- releasing setup of the legacy tunnel.
A tunneling control apparatus for a data transmission between base stations, the apparatus comprising:
- an event/message handler configured to:
- receive data and/or a control signal used to share information for a coordinated multi-point transmission between the base stations;
- and
- establish a tunnel for transmitting the data or the control signal;
- and
- a connection manager comprising a tunnel reservation manager configured to:
- in response to receiving a request for a data rate that exceeds an average value of the estimated range, reserve an estimated range of resources that are to be used to transmit data for the coordinated multi-point transmission between the base stations;
- control a data transmission process using the reserved resource;
- and
- utilize residual resources allocated to one or more other sessions such that the total amount of used resources is within a maximum value of the estimated range.
