Publication number: 20240137854Abstract: Network nodes and methods for control thereof for dynamic network slice selection. An AMF receives a UE request originating from the UE, the UE request being any one of a registration request and a session request. A network slice requester controls a transmitter to transmit a network slice selection request to a PC_NSS. A selection data manager of the PC_NSS determines selection data specifying one or more UE specific parameters affecting network slice selection. A network slice selector selects a network slice assignable for the UE, based on the selection data, determines network slice data and a corresponding network slice routing rule, and transmits them to the AMF. A network slice manager of the AMF controls assignment of a network slice to the UE in dependence on the received network slice data and network slice routing rule.Type: ApplicationFiled: January 3, 2024Publication date: April 25, 2024Inventors: Fuencisla GARCIA AZORERO, Susana FERNANDEZ ALONSO, Victor FERRARO ESPARZA, Angel NAVAS CORNEJO, Ignacio RIVAS MOLINA

Patent number: 11191088Abstract: An apparatus for user plane function, UPF, allocation is described. The UPF is configured to provide a Protocol Data Unit, PDU, connectivity service between a terminal device and a data network on a user plane, and the allocation is based on control information associated with an individual logical PDU entity. The control information defines priority information indicative of a priority of the PDU entity relative to other PDU entities and pre-emption information indicative of at least one of whether the PDU entity is capable of being pre-emptively allocated to a UPF over other PDU entities served by that UPF, and whether the PDU entity when served by a UPF is vulnerable to being re-allocated for pre-emptively allocating other PDU entities to that UPF.Type: GrantFiled: June 6, 2017Date of Patent: November 30, 2021Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Fuencisla Garcia Azorero, Susana Fernandez Alonso, Victor Ferraro Esparza, Angel Navas Cornejo, Ignacio Rivas Molina

Patent number: 10681086Abstract: A method aims at providing a service in a communication network, and comprises the following steps. An access to a service requiring authentication is initiated by a UE (100), An identity management node (300) authenticates the UE, and then sends, to a PCRF node (400), a message comprising: service information for identifying the service to which access is initiated, identification information for identifying the UE, and authentication information determined upon authenticating the UE. The PCRF node determines control rules to be applied to the service for the UE, based on the authentication information and service information. The PCRF node then triggers installation of the control rules in at least one network node (500) handling service data flows (SDF) for the service, to enforce the control rules on traffic associated with the service for the UE. The invention also relates to devices and computer programs for carrying such as method.Type: GrantFiled: March 11, 2014Date of Patent: June 9, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Filipe Alexandre Rodrigues De Moura Leitao, Victor Ferraro Esparza, Fuencisla Garcia Azorero, Jonas Hogberg

Patent number: 10673817Abstract: The invention relates to a method, by a policy controller 100, for generating policy rules for data packet flows in a communications network. The policy controller 100 has access to a policy database 130 and stores a service level agreement. The service level agreement contains a plurality of different service level identifiers, each service level identifier being associated with a set of conditions that govern the policy rules to be applied to the data packet flows in the communications network. The method comprises the following steps: An authorization request is received for a data packet flow, the authorization request comprising service information for a service and a service level identifier. The policy database 130 is accessed and the set of conditions associated with the received service level identifier is determined. Further, based on the determined set of conditions, a policy rule to be applied to the data packet flow is generated.Type: GrantFiled: January 26, 2015Date of Patent: June 2, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Fuencisla Garcia Azorero, Victor Ferraro Esparza, Ignacio Rivas Molina, Filipe Alexandre Rodrigues de Moura Leitao
