Methods, systems, and computer program products are provided for carrier configuration and monitoring of communication devices in a shared communication environment. In some implementations, a carrier configuration may be performed in a radio access network compliant radio unit (RU), where one or more distributed units (DU) may be associated with different carriers and/or different network operators. Further, monitoring of each such DU and/or any its management connections may be executed, whereby the remote radio unit may be configured to determine individual carrier states when there is a specific DU failure.

In general, the current subject matter relates to handling core network connection failure. In some implementations, an F1 interface can be set up between a centralized unit (CU) of a base station and a distributed unit (DU) of the base station. Setting up the F1 interface can include transmitting core connectivity status information from the CU to the DU, and the core connectivity status information can indicate to the DU whether or not the CU has connectivity with a core network.

A method of performing slice specific overload control in a wireless communication system, including detecting a slice specific overload in a Radio Area Network (RAN) based on a Physical Resource Block (PRB) utilization threshold and a predetermined period of time, wherein a particular RAN network slice is identified via Network Slice Selection Assistance Information (S-NSSAI); mapping slices to access categories in the RAN; and informing the RAN of actions to take to mitigate the detected slice specific overload.

A method, an apparatus, and a computer program product for scaling of subscriber capacity in a cloud native radio access network (RAN). A processing capacity being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments is determined. The determined processing capacity is compared to at least one predetermined threshold in a plurality of predetermined thresholds. Based on the comparing a determination is made whether to change an assignment of the processing capacity.

A method, an apparatus, and a computer program product for scaling one or more processing resources in a wireless communication system. One or more processing resources being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments are monitored. Based on the monitoring, a determination of whether to change an assignment of one or more processing resources in the plurality of containers is made. Based on the determination, the assignment of one or more processing resources is changed.

A method, an apparatus and a computer program for providing end-to-end slicing in wireless communications systems. Profiles of a plurality of network slices of a wireless communications system are determined. Each network slice in the plurality of network slices has one or more communication components logically isolated from one or more communication components of another network slice in the plurality of network slices. Based on the determined profiles and a request received from the user device, a network slice in the plurality of network slices is selected for transmission of data associated with the user device. Using the selected network slice, data associated with the user device is transmitted.

A UE reports an ECGI of a target eNB/gNB missing an X2/Xn interface to a source eNB/gNB. The source eNB/gNB sends a configuration transfer message to a network element to get the X2/Xn interface TNLA of the target eNB/gNB. The source eNB/gNB initiates an initial backoff timer and an exponential backoff multiplier. The source eNB/gNB determines whether the TNLA discovery procedure time is equal to or greater than a current backoff time, the current backoff time being equal to a previous backoff period multiplied by the exponential backoff multiplier. The source eNB/gNB may resend the configuration transfer message to the network element when a previous TNLA discovery procedure time for the same ECGI is equal to or greater than the current backoff time, and not resend the configuration transfer message to the network element when the previous TNLA discovery procedure time is less than the current backoff time.

A method, a system, and a computer program product for selecting fronthaul links in a wireless communication system. One or more link delays are determined. The link delays are associated with one or more communication links in the plurality of communication links communicatively coupling a first communication device and a second communication device. Using the determined link delays, a communication link transmission priority of the communication links for transmission of one or more data packets is determined. A listing of prioritized communication links is generated. At least one communication link in the prioritized communication links is selected for transmission of data packets between the first and second communication devices. Using the selected communication link, the data packets are transmitted between the first and second communication devices.

A method, an apparatus, a system, and a computer program product for performing dynamic spectrum sharing in a wireless communication system. A control plane message identifying a radio resource in a plurality of radio resources for controlling transmission of a data packet in a plurality of data packets between a plurality of communication devices is generated. The generated control plane message is transmitted. Using the identified radio resource, transmission of the data packet is controlled in a user plane.

A method, an apparatus, a system, and a computer program product for resource isolation in wireless communication systems. A communication network in a plurality of communication networks of a wireless communications system is identified. Each communication network in the plurality of communication networks has one or more communication components logically isolated from one or more communication components of another communication network in the plurality of communication networks. The identified communication network is selected for transmission of data associated with a user device. Data associated with the user device is transmitted using the identified communication network.

Methods and apparatuses for acquisition of an Address Resolution Protocol (ARP)/IPv6 neighbour cache at a user plane function (UPF) entity without performing deep packet inspection for every packet that traverses a network. The ARP broadcast/Internet Control Message Protocol version 6 (ICMPv6) neighbour solicitation multicast from any Ethernet client (a user equipment (UE) or clients behind the UE or clients in a data network (DN)) is responded to by the UPF entity itself, by looking up the ARP/IPv6 Neighbour cache built in the UPF entity, irrespective of whether the UPF entity acts as the core Ethernet switch or whether the core Ethernet switch is in the DN. The solution is simplified to always intercept ARP at the UPF entity and respond to it based on a local ARP/IPv6 Neighbour cache.
