Bearer-based and mobile terminal-based mobility indicators are disclosed. These enable the core network to indicate radio-bearer-level or terminal-level mobility preferences for a mobile terminal to the RAN, enabling the RAN to take bearer-level or terminal-level mobility decisions. An example method is carried out in a core network node of a wireless communication system that includes a first radio access network,RAN,supporting a first radio access technology, RAT, and a second RAN supporting a second RAT. The example method includes signaling(720), to a node in the first RAN, a mobility indicator that indicates whether mobility with respect to a second RAT is allowed or disallowed for a particular radio bearer or for the entire context of a mobile terminal, or whether there is a preference for or against mobility to the second RAT. In some embodiments, the first RAT is a 3GPP RAT and the second RAT is Wi-Fi. |
