First Claim
Patent Images
1. A method, comprising:
- determining that a user equipment is receiving a session for a multimedia broadcast-multicast service, the multimedia broadcast-multicast service using a preferred frequency layer;
changing at least one cell selection or re-selection parameter for the user equipment such that when a subsequent cell selection or re-selection occurs the user equipment favors cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells; and
transmitting to one or more user equipment a message indicating a value for a parameter that, if adopted by the one or more user equipment, would inhibit the one or more user equipment from subsequently selecting a different cell from a cell with which the one or more user equipment is currently operating.

Abstract
A method to control cell selection and/or re-selection in a communication system comprising a plurality of cells with which terminal devices may communicate, the method including the steps of: determining that a terminal device is to start a session for a certain service, the service using a reception frequency; based on that determination, changing at least one cell selection and/or re-selection parameter in respect of the terminal device with the effect that a subsequent cell selection and/or re-selection performed by the device would favor cells that use the reception frequency used in the service session over other cells.

10. A method, comprising:
-
transmitting to one or more user equipment which are receiving a session for a multimedia broadcast-multicast service, the multimedia broadcast-multicast service using a preferred frequency layer, a message indicating a value for at least one cell selection or re-selection parameter such that when a subsequent cell selection or re-selection occurs the one or more user equipment favor cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells; and transmitting to one or more user equipment a second message indicating a value for a second parameter that, if adopted by the one or more user equipment, would inhibit the one or more user equipment from subsequently selecting a different cell from a cell with which the one or more user equipment is currently operating. - View Dependent Claims (11, 12, 13)

14. A method, comprising:
-
receiving, at a user equipment, a message indicating a value for at least one cell selection or re-selection parameter, wherein the user equipment is configured to receive a session for a multimedia broadcast multicast service, the multimedia broadcast-multicast service using a preferred frequency layer, wherein when a subsequent cell selection or re-selection occurs the user equipment favors cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells; adopting the value indicated in the message for the parameter in the user equipment; receiving at the user equipment a second message indicating a value for a second parameter that, if adopted, would inhibit the subsequent selection for the user equipment of a different cell from a cell with which the user equipment is currently operating; and
adopting the value indicated in the second message for the second parameter in the user equipment. - View Dependent Claims (15, 16, 17, 18, 19)

20. An apparatus, comprising:
-
at least one memory including computer program code; and at least one processor, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to determine that a user equipment is receiving a session for a multimedia broadcast multicast service, the multimedia broadcast-multicast service using a preferred frequency layer; change, based on the determination, at least one cell selection or re-selection parameter with respect to the user equipment, such that when subsequent cell selection or re-selection occurs the user equipment favors cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells; and transmitting to one or more user equipment a message indicating a value for a parameter that, if adopted by the one or more user equipment, would inhibit the one or more user equipment from subsequently selecting a different cell from a cell with which the one or more user equipment is currently operating. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. An apparatus, comprising:
-
at least one memory including computer program code; and at least one processor, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to transmit to one or more user equipment which are receiving a session for a multimedia broadcast-multicast service, the multimedia broadcast-multicast service using a preferred frequency layer, a message indicating a value for at least one cell selection or re-selection parameter such that, when a subsequent cell selection or re-selection occurs the one or more user equipment favor cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells; and
tocause the apparatus at least to transmit to one or more user equipment a second message indicating a value for a second parameter that, if adopted by the one or more user equipment, would inhibit the one or more user equipment from subsequently selecting a different cell from a cell with which the one or more user equipment is currently operating. - View Dependent Claims (31, 32)

33. An apparatus, comprising:
-
at least one memory including computer program code; and at least one processor, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive a message indicating a value for at least one cell selection or re-selection parameter such that when a subsequent cell selection or re-selection for the apparatus which is receiving a session for a multimedia broadcast multicast service occurs, the multimedia broadcast-multicast service using a preferred frequency layer, the apparatus favors cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells; adopt the value indicated in the message for the parameter; and
tocause the apparatus at least to receive a second message indicating a value for a second parameter that, if adopted by the apparatus, would inhibit the apparatus from subsequently selecting a different cell from a cell with which the apparatus is currently operating; and
adopt the value indicated in the second message for the second parameter. - View Dependent Claims (34, 35)
