The present specification provides a method by which user equipment (UE) is connected to a base station. The method comprises the steps of: receiving broadcasted information from the base station, wherein the broadcasted information includes information of network slices connected to the base station and capability information of the base station; determining a type indicating a service to be provided or a kind of operation on the basis of the information on the network slices and capability information on the base station; transmitting, to the base station, a connection request message including information on the determined type; and receiving a connection accept message for a first network slice among the network slices connected to the base station. The first network slice can be selected by the base station on the basis of the information on the type.

An information handling system of a first gateway access point in a wireless network includes at least one wireless adapter for receiving a plurality of reply messages including information that can be used to calculate a plurality of traffic factor values describing traffic flow between one of a plurality of gateways in the wireless network and a cloud computing resource, and a processor executing code instructions of a wireless network gateway sink nomination system. For each of the plurality of traffic factors, the wireless network gateway sink nomination system may calculate and store within a memory a traffic factor value for each of the plurality of gateways, based on the reply messages, associate each calculated traffic factor value with the gateway from which the reply message used to calculate each value was received, identify a most desirable calculated traffic factor value for each of the gateways, identify a most desirable sink gateway from the plurality of gateways based on the most desirable calculated traffic factor values, transmit the identity of the most desirable sink gateway to each of the plurality of gateways, and transmit data bound for transmission to the cloud computing resource to the most desirable sink gateway for delivery of the data to the cloud computing resource.

Techniques for handover into eIMTA enabled cells are disclosed. In an aspect, a target cell reconfigures RRC connection with a UE after completed handover to enable eIMTA and/or CoMP for the UE. In another aspect, a target cell includes eIMTA configuration information in a handover command to a UE. In another aspect, the target cell may estimate a virtual cell identity to generate the eIMTA configuration information and delay scheduling transmissions to the UE by flexible subframes until after handover is complete and the correct eIMTA configuration information confirmed by measurement or else corrected by RRC connection reconfiguration. In other aspects, the target cell may determine the correct virtual cell identity before handover, either by measuring SRS of the UE, or by receiving information in a handover request indicating results of CSI-RS measurement, by the UE, of virtual cells of the target cell.

A radio terminal 10 comprises a controller 13 configured to notify, when a condition to perform a switching process of switching a connection target from a mobile communication network to a wireless LAN is satisfied, a source radio base station provided in the mobile communication network of information indicating that the condition to perform the switching process is satisfied.

A method, apparatus and system for establishing S1 signaling connections in an evolved network are disclosed. A source evolved NodeB (eNodeB) sends a handover request message to a target eNodeB to initiate a handover procedure during that a user equipment (UE) is handed over from the source eNodeB to the target eNodeB. The handover request message includes information about an original S1 signaling connection parameter. When the UE enters the target cell, the target eNodeB allocates a new S1 signaling connection parameter and sends a handover complete message to an evolved packet core (EPC). The handover complete messages carries the original S1 signaling connection parameter received from the source eNodeB and the allocated new S1 signaling connection parameter about the target eNodeB. With the present disclosure, the inability of the target eNodeB to establish an S1 signaling connection with the EPC in the related art is effectively solved.

A wireless communication network serves a wireless User Equipment (UE) over wireless network slices using different handover types. The wireless communication network selects one of the wireless network slices for the wireless UE. The wireless communication network identifies one of the different handover types for the wireless UE based on the selected one of the wireless network slices. The wireless communication network serves the wireless UE over the selected one of the wireless network slices. The wireless communication network wirelessly hands-over the wireless UE from a source wireless access node to a target wireless access node using the identified one of the different handover types.

A method for maintaining a connection of mobile user equipment to a core network, and a communication network are disclosed. The method comprises the steps of providing a multi-channel communication link between a user equipment at a first location and a plurality of aerial vehicles, determining that the user equipment is moving whereby a loss of connectivity via the multi-channel communication link may occur, and subsequently, via a handover step, transferring communication between the user equipment and a core network from communication via the multi-channel communication link to communication via a single channel communication link provided by a respective aerial vehicle.

A wireless communication system determines a first network slice and a second network slice to serve a user application. The wireless communication system identifies a performance level for the first network slice to serve the user application. The wireless communication system exchanges first user data using the first network slice to serve the user application. The wireless communication system determines actual performance of the first network slice to serve the user application. The wireless communication system compares the actual performance of the first network slice to the performance level for the first network slice, and in response, stops the exchange of the first user data to serve the user application using the first network slice and starts an exchange of second user data to serve the user application using the second network slice.

Methods, systems, and devices for wireless communication are described. A method may include determining to modify current-allowed network slices used by a user equipment (UE) based on a network-trigger; identifying new-allowed network slices for the UE based on the determining; selecting a target access and mobility management function (AMF) based on the new-allowed network slices, the target AMF is accessible by the source AMF; and triggering an AMF relocation based on the selecting.

Aspects of the subject disclosure may include, for example, accessing a service by a first network operating within a first wireless spectrum, wherein the service includes control and data forwarding operations of the first network are separate and configured to facilitate forwarding of user data via the data forwarding operations. A second network is identified operating within a second wireless spectrum. A request that the accessing of the network service be transferred to the second network is made without interrupting the forwarding of the user data. A response to the request is detected via the control operations, also without interrupting the forwarding of the user data. Responsive to an indication that the second network has been configured to accommodate a redirection of the forwarding of the user data from the first network to the second, the redirection is facilitated. Other embodiments are disclosed.
