A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

It is presented a method for error handling during a Mobile Terminated, MT, call to a User Equipment, UE, in a cellular system. The method is performed by a network device being an alternative Mobility Management Entity, MME, of the cellular system. The method comprises the steps of: failing to forward a paging request to a serving MME, at which the UE is registered; and paging the UE using a Circuit Switched, CS, paging. A corresponding network device, User Equipment, computer program and computer program product are also presented.

A system configured to analyze cellular connectivity information for at least one wireless network and at least one wireless device includes a processor configured to receive cellular connectivity information from at least one wireless network for at least one wireless device; the processor further configured to receive geographic location information from the at least one wireless network for the at least one wireless device. The system also includes a database configured to store the cellular connectivity information, the geographic location information, and equipment type information related to the at least one wireless device. The processor further configured to analyze the cellular connectivity information and determine a wireless device having poor wireless service performance based on the analysis of the cellular connectivity information. The disclosure additionally includes a process to analyze cellular connectivity information for at least one wireless network and at least one wireless device.

Disclosed are a method and device for supporting mobility for a NWDAF in a wireless communication network. The method may comprise the steps of: deciding to transfer analytics subscriptions of a network function (NF); determining a target NWDAF to which the analytics subscriptions are to be transferred, on the basis of at least one among a terminal location, the analytics subscriptions, a consumer NF and a target area; transmitting, to the target NWDAF, a subscription transfer request message including first subscription information related to the analytics subscriptions; receiving, from the target NWDAF, a subscription transfer response message including second subscription information related to at least one analytics subscription, generated on the basis of the first subscription information; and, on the basis of the second subscription information, requesting, to a source NF, subscription cancelation of the corresponding analytics subscription among the at least one analytics subscriptions.

A method for seamless WiFi roaming of a multi-radio station when transitioning from an initial access point to a target access point, wherein the method comprises activating a second communication link between the multi-radio station and the target access point while a first communication link between the multi-radio station and the initial access point is still active, and after said activating, deactivating the first communication link between the multi-radio station and the initial access point.
