MOBILE HOTSPOT WITH IMS CALL PRIORITIZATION

摘要

The application relates to a wireless relay device which acts as a mobile hotspot, in particular to enable non-4G-LTE-capable IMS clients to establish IMS connections to the 4G-LTE network. Such a device is also referred to as MiFi router, SoftAP or software hotspot. In order to ensure QoS for all IMS clients on the LTE network, there may be one or more policies in place limiting the number of concurrent connections between IMS clients and the network via a particular relay device. Such policies might operate on a first-come-first- serve basis. However, in certain situation, such policies might be unsatisfactory because different connections might be associated with different priorities. Therefore the application proposes to determine the priority associated with the device seeking connection establishment (522) and handle the connection accordingly, i.e. either to terminate a connection of lower priority (523) or to reject the connection if the priority is lower than the priorities of the other connections (526).
