Abstract
Determining whether service via a core network of the first type is available from the second cell. The method further comprises establishing a connection via the second cell by transmitting a message including a first indication, the first indication based on at least a portion of the identifier, and when service via a core network of the first type is not available from the second cell, transmitting in the message a second indication, the second indication indicating that the identifier was received from a core network different from the second type, without identifying the first type of core network.
