Abstract
In a telecommunication system, a method for improved handover signaling includes temporarily enhancing the radio environment of a user engaged in handover signaling by muting one or more dominant interfering cells during the signaling process, and coordinating the muting with the actual handover signaling.
Claims30
A method for hard handover of a radio connection in a radio communication system, said system including a radio connection established between a user equipment and a single serving base station, the method comprising the steps of:
- determining a need for a hard handover of the radio connection where the single serving base station passes on the radio connection in its entirety to another serving base station,
- temporarily muting at least one node interfering with the radio connection, and
- coordinating the temporary muting of said interfering node with hard handover signaling between said user equipment and said single serving base station to temporarily reduce interference during at least part of the hard handover signaling to enable reliable transmission of the hard handover signaling.
An apparatus for hard handover of a radio connection in a radio communication system between a user equipment and a single serving base station, comprising electronic circuitry configured to:
- determine a need for a hard handover of the radio connection where the single serving base station passes on the radio connection in its entirety to another serving base station;
- temporarily mute at least one interfering node interfering with the radio connection;
- and
- coordinate the temporary muting of said interfering node with hard handover signaling between said user equipment and said single serving base station to temporarily reduce the interference during at least part of the hard handover signaling to enable reliable transmission of the hard handover signaling.
A node for hard handover of a radio connection in a radio communication system between a user equipment and a single serving base station to another base station, comprising electronic circuitry configured to temporarily mute a node interfering with the radio connection to temporarily reduce the interference during at least part of the hard handover enable reliable transmission of signaling for the hard handover.
A control node for hard handover of a radio connection in a radio communication system between a user equipment and a single serving base station, comprising electronic circuitry configured to:
- determine a need for a hard handover of the radio connection where the single serving base station passes on the radio connection in its entirety to another serving base station;
- issue muting commands to at least one node interfering with the radio connection to temporarily mute said at least one interfering node;
- and
- coordinate said muting commands with hard handover signaling between said single serving base station and said user equipment to temporarily reduce the interference from the at least one interfering node to enable reliable hard handover signaling.
