Enhanced UE route selection policy (URSP) rule matching
11671891 · 2023-06-06 · ·

A method for UE route selection policy (URSP) rule matching is proposed. URSP is used by a UE to determine if a detected application can be associated to an established PDU session, can be offload to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU session. The UE first finds a non-default URSP rule with a matching traffic descriptor to the application. When the UE fails to find existing PDU session or setup new PDU session with any or the route selection descriptors of the non-default URSP rule, the UE moves to another non-default URSP rule, if any, and try the matching. If all non-default URSP rules cannot be matched with the application, then the UE tries the default URSP rule, which includes a match-all traffic descriptor.

Return-link routing in a hybrid network

Embodiments provide techniques for providing return-link routing in a hybrid communications network that includes a number of different networks having different characteristics. User terminal routing systems (UTRSs) provide interfaces between local user networks and the multiple communications networks of the hybrid network. Each UTRS can include a routing table having stored mappings that are populated according to forward-link communications (implicitly or explicitly), each associating a respective one of a plurality of routing table entries with one of the communications networks. When a UTRS receives return-link data from its respective local user network, the received data indicates a destination node. The UTRS can determine which of the stored mappings corresponds to the destination node and can route the received return-link data over a selected one of the communications networks in accordance with the identified one of the mappings.

Handling of collision between SR procedure and PDU session establishment procedure for PDU session handover
11197216 · 2021-12-07 · ·

A method for handling PDU session handover procedure collision in a next generation NG/5G system is proposed. Both network-triggered and UE-triggered PDU session handover procedures can occur at the same time. If Paging or Notification for PDU session handover comes before UE initiated MO PDU session establishment procedure for PDU session handover, then UE should avoid sending the PDU session establishment request for PDU session handover but only send the service request as a response to paging. On the other hand, if Paging or Notification for PDU session handover comes after UE initiated MO PDU session establishment procedure for PDU session handover, then UE should avoid sending the service request for PDU session handover but proceed with the PDU session establishment procedure as a response to paging.

Managing Access To Cloud-Hosted Applications Using Domain Name Resolution

Edge clusters execute in a plurality of regional clouds of a cloud computing platforms, which may include cloud POPs. Edge clusters may be programmed to control access to applications executing in the cloud computing platform. Edge clusters and an intelligent routing module route traffic to applications executing in the cloud computing platform. Cost and latency may be managed by the intelligent routing module by routing requests over the Internet or a cloud backbone network and using or bypassing cloud POPs. The placement of edge clusters may be selected according to measured or estimated latency. Latency may be estimated using speed test servers and the locations of speed test servers may be verified.

Methods, systems, and computer readable media for establishing message priority in network slices based on quality of service parameters

A method for establishing message priority in network slices based on quality of service (QoS) parameters includes receiving, by a network slice configuration service provider entity and from a network slice management service provider entity, a network slice creation notification message containing at least a QoS profile corresponding to a created network slice, utilizing the QoS profile to derive a service based interface (SBI) message priority (SMP) associated with the network slice, and providing the SMP to a requesting access and mobility management function (AMF) entity in response to receiving a network slice selection request message from the AMF entity, wherein the AMF entity assigns the SMP level value to network traffic directed to the network slice.

MULTI-CHANNEL MESSAGE EXCHANGE SYSTEM

A multi-channel message exchange system selects a service provider that is best suited to deliver each individual message for customers of the message exchange system. The message exchange system selects a service provider based on customer criteria provided by the customer, data structures provided by the service providers, quality scores describing performance of the service providers, channels used by the service providers to deliver messages, or any suitable combination thereof. The message exchange system may select the service provider that provides the best combination of quality of service, value, and delivery channel given the customer's specific needs. The data structures may geographic jurisdictions in which the service provider provides message delivery, channels through which the service provider is willing to deliver messages, or any suitable combination thereof.
