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

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.

13. A method to control cell selection/re-selection in a system where multicasting is used to deliver information to several terminal devices, the method comprising the steps of:
-
determining which terminal devices are to start a multicast session; and
changing, based on the determining step, at least one cell selection/re-selection parameter for the terminal devices so that cell selection/re-selection favors cells which use a reception frequency used in the multicasting session compared to other cells.

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

15. A method to control cell selection or re-selection in a communication system comprising a plurality of cells with which terminal devices may communicate, the method comprising the steps of:
-
transmitting to a plurality of terminal devices a message indicating a value for a cell selection or re-selection parameter that, if adopted by a terminal device, would cause a subsequent cell selection or re-selection performed by the device to favor cells on which a service session is available over other cells; and
adopting the value indicated in the message for the parameter in one or more of the plurality of terminal devices. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A network device, comprising:
-
receiving means for receiving a notification of whether a certain service session has started or not; and
changing means for changing, based on said notification, at least one cell selection/re-selection parameter for terminals so that cell selection/re-selection favor cells which use a reception frequency used in said service session compared to other cells. - View Dependent Claims (25)

24. A network device, comprising:
-
a processor configured to determine that a terminal device is to start a session for a service, the service using a reception frequency; and
a controller configured to change, based on such a determination, at least one cell selection or re-selection parameter with respect to the terminal device, with the effect that a subsequent cell selection or re-selection performed by the device would favor cells that use the reception frequency over other cells.
