The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods and systems of how an application function can request the Fifth Generation (5G) core network to perform a specific action, when a network slice quota reaches a maximum limit or when the behavior of the UE(s) falls outside the expected communication behavior.

A system and method for managing interference between different enterprises operating over the same spectrum. The system includes a central unit of a first enterprise associated with a first cell site; a central unit of a second enterprise associated with a second cell site; and an interface for connecting the central unit of the first enterprise to the central unit of the second enterprise and configured to transmit load information; wherein a central unit of either enterprise is configured to share load information without requiring a standard form between each enterprise via the interface to minimize interference between each enterprise when both enterprises are operating in the same spectrum and an overlapping coverage region between each cell site.

Methods and systems for providing an enhanced proximity services. The method includes monitoring, by a proximity controller provisioned in a preferred network, dual subscriber identification module (SIM) dual subscriber (DSDS) devices operating in the preferred network, detecting, by the proximity controller, a DSDS device operating in a non-preferred network, wherein the DSDS devices and the DSDS device are configured to switchably operate in one of the preferred network or the non-preferred network based on coverage, locating, by the proximity controller, from the monitored DSDS devices a DSDS device proximate to the DSDS device operating in the non-preferred network, and enabling, by the proximity controller, the proximate DSDS device and the DSDS device operating in the non-preferred network to establish a sidelink communication channel between the proximate DSDS device and the DSDS device operating in the non-preferred network for offloading data communications from the non-preferred network to the preferred network.

A method for utilizing a default channel during unused periods of timeslots to join, communicate, and/or synchronize with a network comprising determining a time slot is idle; in response to determining the time slot is idle tuning to a default channel while the timeslot is idle; receiving a message on the default channel; and optionally transmitting a subsequent message on the same channel.

Methods and systems for sharing aerial assets amongst terrestrial network operators. Embodiments enable sharing of aerial assets amongst the terrestrial network operators and facilitate on-demand deployment of the aerial cells to improve coverage and capacity of the terrestrial network operators. Embodiments allow sharing of aerial assets such as aerial cell mount, backhaul, an aerial RAN, and aerial spectrum using sharing architectures. Embodiments provide a managing entity for forecasting data traffic pertaining to the terrestrial network operators and optimizing the deployment of the aerial cells, based on the forecasted data traffic, for enabling strategic deployment of the aerial cells. Embodiments ensure that the resources of the aerial cells are effectively utilized and the number of aerial cells required for enhancing the capacity of the terrestrial network operators is minimized.

An electronic device determines that a first network is inaccessible and that non-prioritized services associated with a second network are unavailable. In response, the electronic device communicates non-prioritized data via a third network. Additionally, in response to determining that prioritized services associated with the second network are available, the electronic device transmits a priority message using the second network while communicating the non-prioritized data via the third network. In response to determining the first network is accessible, the electronic device communicates additional non-prioritized data and an additional priority message using the first network.

A method of handling multi-access (MA) Protocol data unit (PDU) session handover is proposed. A UE and network can support Access Traffic Steering Switching and Splitting (ATSSS) functionalities to distribute traffic over 3GPP access and non-3GPP access for the established MA PDU session. An ATSSS-Supported UE first establishes a MA PDU Session on both 3GPP and non-3GPP access in a currently registered PLMN which is an ATSSS-Supported network. The UE then moves from the ATSSS-Supported network to an ATSSS-not-Supported network and finally reaches another ATSSS-Supported network. In one novel aspect, a solution is provided on how to handle the ongoing MA PDU Session with two accesses under handover scenarios between ATSSS-Supported and ATSSS-not-Supported networks. Furthermore, if the ongoing MA PDU Session cannot handover, a solution is provided on how to handle the MA PDU Session.

A User Equipment (UE) includes: a transmitter configured to transmit, in a case that a timer is running for a piece of Single Network Slice Selection Assistance Information (S-NSSAI) at a time when a Public Land Mobile Network (PLMN) is changed, a Protocol Data Unit (PDU) session establishment request message for an identical piece of S-NSSAI in a changed PLMN without stopping the timer. This configuration allows for provision of a communication control method for the terminal to apply congestion managements expected by the network to the congestion managements applied by the network in 5G congestion management to which multiple congestion managements are applied.

Systems and methods to support coexistence of multi-connectivity functions in 3GPP network and non-3GPP networks for UEs and to provide traffic routing policies and coordinate with ATSSS operation in 5GS are described. The AF subscribes to a registration-state notification event. A report is sent to the AF from the PCF or NEF. The report indicates a current registration state of a UE and is triggered when the registration state of the UE changes. The report may be sent with or without PDU session information, the former of which may be based on a determination by the AMF or the SMF. Traffic steering is enforced by the MAMS among multiple IP sessions coordinated via a single or a multiple PDU sessions in the 3GPP network.

A wireless communication device uses multiple wireless communication services for communication between an in-vehicle device of a vehicle and an external device. The wireless communication device acquires a delay characteristic value for each wireless communication service from a network device. The delay characteristic value is an upper limit of an estimated range of delay time in communication. The wireless communication device acquires an allowable delay amount indicating a length of an allowable communication delay time from the in-vehicle device. The wireless communication device allocates a wireless communication service, which is relatively small in the delay characteristic value among the wireless communication services, to the in-vehicle device that is small in the allowable delay amount.
