Abstract: Methods and systems for coordinated change of Protocol Data Unit (PDU) Session Anchors (PSAs) are provided. According to one embodiment, a method for coordinated change of PSAs comprises, at a node for maintaining PSA change status for PDU sessions, receiving a request for a PSA change or handover for a first PDU session having a first PSA, where the first PDU session and a second PDU session having a second PSA different from the first PSA are redundant PDU sessions with each other. If the second PDU session is undergoing a PSA change or handover, the request to change the first PDU session is denied; otherwise, the request to change the first PDU session is granted, and the second PDU session will not be allowed to be changed until the PSA change or handover for the first PDU session is complete.

Abstract: A network node (300, 400) a Wireless Communication Network (WNC) bridge (130) receives scheduling information from a Central Network Controller (CNC) (120A). The network node (300, 400) calculates the RAN assistance information based on the scheduling information. The network node (300, 400) forwards the RAN assistance information towards a RAN scheduler that schedules RAN traffic passing through the WCN bridge (130).

Abstract: A method for establishing a Protocol Data Unit (PDU) Session(s) is disclosed. In examples disclosed herein, a device (e.g., a wireless device) uses a unique Port Number(s) (e.g., an internal physical or logical Port Number) to search for a matching User Equipment (UE) Route Selection Policies (URSP) rule(s) having a Traffic Descriptor(s) that matches the unique Port Number(s). The device then determines whether there exists a matching PDU Session(s) associated with a Route Selection Descriptor(s) of the matching URSP rule(s). Accordingly, the device can reuse the matching PDU Session(s) in a presence of the matching PDU Session(s) or establish a new PDU Session(s) in an absence of the matching PDU Session(s). By using the unique Port Number(s) as the Traffic Descriptor(s) in the URSP rule(s), it is possible to simplify configuration of the device, especially for redundant traffic handling.

A method for avoiding jitter includes receiving, an ingress point of the communication network, a packet, wherein the packet is received at the ingress point at a time within a particular time slot. The method also includes the ingress point creating a modified packet that includes the received packet and a slot identifier indicating the particular time slot in which the packet was received, the ingress point transmitting (s406) the modified packet towards an egress point of the communication network.

Abstract: A first orchestrator (20-1) for a first domain (10-1) is configured for multi-domain orchestration. The first orchestrator (20-1) receives an inbound orchestration request (22) that requests orchestration of one or more inbound targets (24) and that includes one or more records (26). The one or more records (26) either indicate an ancestry of each of the one or more inbound targets (24) or indicate an ancestry of the inbound orchestration request (22). The first orchestrator (20-1), based on the one or more records (26) included in the inbound orchestration request (22), evaluating whether or not to send from the first domain (10-1) to a second domain (10-2) an outbound orchestration request (28) that requests orchestration of an outbound target (30). The outbound target (30) is one of, or is a descendant of at least one of, the one or more inbound targets (24).

Abstract: A wireless communication network (12) includes one or more nodes (10, 40) that individually or cooperatively prevent affiliated communication modules (14) from being handed over at the same time. Affiliated communication modules (14) provide a machine, device, or other entity (16) with redundant access to the network (12) and preventing the simultaneous handover of affiliated communication modules (14) within the network (12) reduces the chance that the involved entity (16) will lose radio connectivity or experience an interruption in its communications. Although not limited to Critical Machine Type Communication, C-MTC, applications, such operations improve connection redundancy and reliability for C-MTC entities that use two or more communication modules (14) for redundant access to a wireless communication network (12).

Abstract: A wireless communication network (12) includes one or more control nodes (10) that recognize redundancies between communication modules (14) and control handover of such modules (14) to enforce connection diversity between them and the network (12). Advantageously, the methods and apparatus shown by way of example in this disclosure enforce connection diversity without the need for statically configured diversity schemes that are complex to plan and difficult to maintain.
