Mobile communication system, UE, handover control method for use thereof and program thereof

A mobile communication system that performs handover control, when any of UEs moves to an adjoining cell, over those UEs, comprising in each of said UEs:

• means of searching for a cell needed for obtaining required communication quality by switching the handover destination cell during communication.

A mobile communication system that performs handover control, when any of UEs moves to an adjoining cell, over those UEs, comprising in each of said UEs:

• means of excluding from said handover destination cells any handover destination cell whose temporary communication cut-off during communication would not affect communication quality after rake synthesis.

A UE wherein handover control takes place when moving to an adjoining cell, comprising:

• means of measuring the reception quality of a dedicated physical channel allocated, together with a common pilot channel over which common transmission takes place within the cell, for communication use;
• and
• means of determining the handover destination cell on the basis of the result of that measurement.

A UE wherein handover control takes place when moving to an adjoining cell, comprising:

• means of searching for a cell needed for obtaining required communication quality by switching during communication said handover destination cell.

A UE wherein handover control takes place when moving to an adjoining cell, comprising:

• means of excluding from said handover destination cells any handover destination cell whose temporary communication cut-off during communication would not affect communication quality after rake synthesis.

A handover control method for use in a mobile communication system wherein, when any of UEs moves to an adjoining cell, handover control over the UE takes place, comprising in each of said UEs:

• a step of measuring the reception quality of a dedicated physical channel allocated, together with a common pilot channel over which common transmission takes place within the cell, for communication use to each of said UEs;
• and a step of determining a handover destination cell on the basis of the result of that measurement.

A handover control method for use in a mobile communication system wherein, when any of UEs moves to an adjoining cell, handover control over the UE takes place, comprising:

• a step of searching for a cell needed for obtaining required communication quality by switching during communication said handover destination cell.

A handover control method for use in a mobile communication system wherein, when any of UEs moves to an adjoining cell, handover control over the UE takes place, comprising in each of said UEs:

• a step of excluding, in said handover control, from said handover destination cells any handover destination cell whose temporary communication cut-off during communication would not affect communication quality after rake synthesis.

A program of a handover control method for use in a mobile communication system wherein, when any of UEs moves to an adjoining cell, handover control over the UE takes place, the program causing the computer of said UE to execute processing, comprising:

• a process of measuring the reception quality of a dedicated physical channel allocated, together with a common pilot channel over which common transmission takes place within the cell, for communication use to each of said UEs;
• and
• a process of determining a handover destination cell on the basis of the result of that measurement.
