Method for transmitting service information between network nodes for MBMS service in mobile communication system
First Claim
1. A method for transmitting service information between network nodes in a wireless system providing one or more multimedia broadcast/multicast service (MBMS), wherein when a terminal (user equipment (UE)) is moved from a first network node to a cell managed by a second network node, the first network node receives status information of the cell from a third network node.

Abstract
In a method for transmitting service information between network nodes in a wireless system providing one or more multimedia broadcast/multicast service (MBMS), when one terminal is moved from a first network node to a cell managed by a second network node, the first network node receives status information of the cell from the second network node, and when the specific terminal is moved into the cell, the first network node selectively transmits an MBMS connection request message to the second network node. In this case, the status information includes MBMS service area information of a neighboring cell with respect to the MBMS service for which the specific terminal has joined and/or information an MBMS function is supported.

- 8. A method for transmitting service information between network nodes in a wireless system providing one or more multimedia broadcast/multicast service (MBMS), wherein when one terminal is moved from a first network node to a cell managed by a second network node, the second network node provides status information of the cell according to a request of the first network node.
- 13. A method for transmitting service information between network nodes in a wireless system providing one or more multimedia broadcast/multicast service (MBMS), wherein when a terminal is moved from a first network node to a cell managed by a second network node, the first network node receives status information of the cell from a third network node, and when the specific terminal is moved into the cell later, the first network node selectively transmits an MBMS connection request message to the second network node according to the stored status information.
- 19. A method for transmitting service information between network nodes in a wireless system providing one or more multimedia broadcast/multicast service (MBMS), wherein when a terminal is moved from a first network node to a cell managed by a second network node, the first network node requests status information of the cell from the second network node, and when the specific terminal is moved into the cell later, the first network node selectively transmits an MBMS connection request message to the second network node according to the received status information.
