Handover from wifi to mobile network

A mobile entity configured to handle a handover of a call at a mobile entity between different types of radio access networks comprising from a WiFi network to a 3GPP mobile communications network, the mobile entity comprising:

• an interface configured to
• transmit a connection request to a radio access network of a second type comprising the 3GPP mobile communications network, the connection request comprising a first indicator indicating that the connection request is for a handover of an ongoing call currently handled by a radio network of a first type comprising the WiFi network,
• transmit a service request to a call control node of the network of the second type comprising the 3GPP mobile communications network, the service request comprising a second indicator indicating that the connection request is for the ongoing call currently handled by the first type of radio network.

A method for operating a call control node of a mobile communications network comprising a 3GPP mobile communications network, the method comprising:

• receiving a service request from a mobile entity to set up a connection, the service request comprising an indicator indicating that the connection request is for an ongoing call currently handled by a different type of radio access network comprising a WiFi network,
• prioritizing the call handling of the ongoing call of the mobile entity in the call control node with a higher priority level than a default priority level assigned for a mobile originating or mobile terminating call.

A Call control node of a mobile communications network comprising a 3GPP mobile communications network, the call control node comprising:

• an interface configured to receive a service request from a mobile entity to set up a connection, the service request comprising an indicator indicating that the connection request is for an ongoing call currently handled by a different type of radio access network comprising a WiFi network,
• at least one processing unit configured to prioritize the call handling of the ongoing call of the mobile entity with a higher priority level than a default priority level in the processing in the call control node.

A method for operating a node configured to allocate radio resources in a radio access network of a mobile communications network comprising a 3GPP mobile communications network, the node comprising:

• receiving a connection request from a mobile entity comprising an indicator indicating that the connection request is for a handover of an ongoing call currently handled by a different type of radio access network comprising a WiFi network,
• allocating radio resources to the mobile entity with a higher priority level than a default priority level allocated to a terminating or originating call.

A node configured to allocate radio resources in a radio access network of a mobile communications network comprising a 3GPP mobile communications network, the node comprising

• an interface configured to receive a connection request from a mobile entity, the connection request comprising an indicator indicating that the connection request is for a handover of an ongoing call currently handled by a different type of radio access network comprising a WiFi network,
• at least one processing unit configured to allocate radio resources to the mobile entity with a higher priority level than a default priority level allocated to a terminating or originating call.
