摘要

Disclosed herein is a method in a radio access network, RAN, node (315) and corresponding method in a core network node (302), for handling roaming rejection in a shared RAN (305), wherein the shared RAN is second CN (301b), the method comprising: forwarding (403), to a core network, CN, node (302) in the first CN (301a) sharing the RAN (305), a request message of a roaming wireless device (308); receiving (404) a reject message from the CN node, wherein the reject message comprises a cause of the rejection and an indicator indicating that the cause qualifies for redirection of the wireless device; determining (405), based on the indicator in the reject message, that the wireless device should be redirected to another CN node (304) in the second CN (301b) sharing the RAN (305); transmitting (406) the request message of the roaming wireless device (308) to the other CN node (304).

主权项

1. A method in a core network (CN) node of a first CN for handling roaming rejections in a shared radio access network (RAN), wherein the shared RAN is shared amongst the first CN and at least a second CN, the method comprising:
receiving from a RAN node in the shared RAN a request message of a roaming wireless device; determining that the request should be rejected; determining a cause of the rejection; determining that the rejection should lead to a redirection of the wireless device ; creating an indicator indicating that the cause of the rejection should lead to a redirection of the request message of the wireless device; and transmitting a reject message to the RAN node, which reject message comprises the cause of the rejection and the indicator.
