Abstract: Methods and systems for ensuring continuity of services on handover from Wi-Fi to cellular networks are disclosed. Embodiments of the disclosure allow a UE to seamlessly engage in a call during a handover, which is triggered on detecting that QoS of the call is less than a threshold within a coverage area of the Wi-Fi. The continuity of the call is ensured by triggering a handover from Wi-Fi to LTE and preventing/reducing handover from Wi-Fi to NR. The UE avails calling services using LTE and data services using NR, by enabling NSA mode. The UE is allowed to avail calling services seamlessly by initiating a handover of the calling services from Wi-Fi to LTE and avail data services seamlessly by initiating a handover of the data services from Wi-Fi to NR. The handover from Wi-Fi to LTE/NR is initiated if QoS of the calling/data services is less than a threshold in Wi-Fi coverage area.

Abstract: In an example, a wired network device receives a first join message originating from a client device associated with a first wireless access point (WAP) connected to another wired network device in a broadcast domain. An entry corresponding to the client device is created in a remote receiver record of the wired network device. In response to the client device transitioning from the first WAP to a second WAP connected to the wired network device, it is determined that the client device is locally connected to the wired network device. Intention of the client device to receive multicast traffic is identified. A second join message directed to the network address of the multicast group and distributed in the broadcast domain. A traffic flow path for the multicast traffic via the wired network device and the second WAP to the client device is configured.

Abstract: Techniques for using simultaneous connectivity for mobility of integrated access and backhaul nodes may include an IAB node establishing a first connection with a first parent node (e.g., second IAB node) associated with a first IAB donor device (e.g., first base station) and establishing a second connection with a second parent node (third IAB node), wherein the second connection is simultaneous with the first connection. The IAB node may also switch the first connection from the first parent node to the second parent node. In doing so, the IAB node may have dual connectivity with the second parent node, where one connection is a master connection and the other connection is a secondary connection.

Abstract: A wide area network (WAN) communication framework having a common control plane and method for using the same are disclosed. In some embodiments, the wide area network (WAN) communication framework comprises: a plurality of management systems, each for controlling access to and traffic for one of a plurality of WANs that include satellite and terrestrial communication networks; a remote unit capable of communicably coupling to the plurality of WANs; and a master network management system (MNMS). The MNMS is communicably coupled to the plurality of management systems and coupled to the remote unit to aggregate control information from the plurality of management systems and the remote unit to determine which WANs of the plurality of WANs for the remote unit to use, wherein the MNMS uses a common control plane communicably coupled to the remote unit for control and routing of control traffic, including information indicating which WANs of the plurality of WANs to which the remote terminal can connect, the common control plane including a single, continuous control channel to which the remote terminal is connectable simultaneously with a connection to a WAN of the plurality of WANs.

Abstract: The present disclosure relates generally to communications, and more particularly to methods, computer program products, wireless devices and related nodes for Dual Active Protocol Stack (DAPS) handover reports. In one example embodiment, a method is performed by a wireless device. A DAPS handover is performed. Also, a type of handover report is determined. Furthermore, a handover report of the determined type is compiled and optionally stored. Still further, the handover report is transmitted to a network node operating as an access node.

Abstract: Systems and methods provide automated generation of neighbor frequency lists for configuration of frequency objects for wireless stations. A computing device selects a target sector carrier of a wireless station of multiple wireless stations in a radio access network and identifies, based on distances from the wireless station, neighboring sector carriers of the target sector carrier. The computing device filters the neighboring sector carriers based on an azimuth of the target sector carrier to form a filtered set of neighboring sector carriers. The computing device calculates a probability of neighboring frequencies for the target sector carrier based on locations of the filtered set of neighboring sector carriers and generates, based on the calculating, a neighbor frequency list for the target sector carrier. The neighbor frequency list is used to configure frequency objects, for the target sector carrier, that ensure seamless handovers within the radio access network.

Abstract: A system described herein may provide a technique for the seamless transfer of services provided by a first Multi-Access/Mobile Edge Computing device (“MEC”) to a User Equipment (“UE”), to a second MEC. Context information associated with a given application for which services are provided by the first MEC may be cached by the UE based on a determination that the second MEC should provide the services, and the UE may provide the cached information to the second MEC in order to seamlessly continue receiving services. The providing of the cached information to the UE and/or to the second MEC may be performed with an elevated priority level, in order to facilitate the seamless providing of the services relating to the application, thus resulting in minimal to no interruption of the user experience associated with the application.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a source base station associated with a source master cell group (MCG), a physical uplink shared channel (PUSCH) repetition in one or more slots of the source MCG during a handover of the UE from the source MCG to a target MCG. The UE may perform, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the handover, wherein PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG are canceled and a counting of the PUSCH repetitions is based at least in part on slots of the source MCG associated with canceled PUSCH repetitions. Numerous other aspects are described.
