Local switching handover local call

2012 
Method on a node (118) core network to manage call connections switched locally in a wireless communication network, comprising the steps of: - receiving a first message (218, 317) indicating that a first computer (102) user connected by connecting locally switched call has been detected in the target base station subsystem, BSS (203); - transmit, activated by the first message (218, 317), a request for change of status of local switching local call, LCLS-Status-Change-Request (220, 318), requesting a change of status of the connection switched call locally to a second computer (104) user, where the message LCLS-Status-Change-request includes a value in its information element, IE, the value "display data DL after the handover", indicating the data receiving downlink user plane, originating from the first computer (102) user, the second computer (104) user via a switched path (109) core network, so that a path (100) user plane data from the first computer (102) to the second user equipment (104) user is switched to the path (109) core network; - receiving, at the node (118) of core network of the target BSS (203), a fourth message (224, 322) indicating that the first device (102) user has completed the transfer and the call connection between the first computer (102) pierced user and the second computer (104) can not switch user locally; - transmitting to a subsystem (114) source base station, in response to the fourth message (224, 322), a fifth message (226, 324) that instructs the release of the call connection switched locally between the first computer (102) and the second user equipment (104) user, after the transfer is completed the first computer (102) user.
