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.
Claims39
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;
- and
- changing, based on the determining, at least one cell selection or re-selection parameter with respect to 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, wherein the at least one cell selection or re-selection parameter comprises a parameter used to prioritize which cells of a communications system are to be selected or reselected for the user equipment.
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, and
- changing, based on the determining, at least one cell selection or re-selection parameter with respect to the user equipment such that when a subsequent cell selection or re-selection occurs the user equipment favors cells using the preferred frequency layer over other cells, wherein the at least one cell selection or re-selection parameter comprises a parameter used to prioritize which cells of a communications system are to be selected or reselected for the user equipment,
- wherein the changing further comprises setting a parameter that reduces responsiveness of the user equipment to high mobility triggers.
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, wherein the at least one cell selection or re-selection parameter comprises a parameter used to prioritize which cells of a communications system are to be selected or reselected for the one or more user equipment.
A method, comprising:
- receiving at a user equipment which is receiving a session for a multimedia broadcast multicast service, the multimedia broadcast-multicast serviced 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 user equipment favors cells providing the multimedia broadcast-multicast service and using the preferred frequency layer over other cells, wherein the at least one cell selection or re-selection parameter comprises a parameter used to prioritize which cells of a communications system are to be selected or reselected for the user equipment;
- and
- adopting the value indicated in the message for the parameter in the user equipment.
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;
- and
- 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, wherein the at least one cell selection or re-selection parameter comprises a parameter used to prioritize which cells of a communications system are to be selected or reselected for the user equipment.
