Publication number: 20240064133Abstract: An enterprise entitlement server is deployed on an enterprise communication platform. The enterprise entitlement server retrieves authorization data from an authorization server controlled by an enterprise. The authorization data indicates to which one or more resources a subject of the enterprise is entitled to subscribe and/or indicates which one or more types of subscription management actions the subject is authorized to perform. The enterprise entitlement server controls management of a subscription for the subject in accordance with the authorization data.Type: ApplicationFiled: November 22, 2021Publication date: February 22, 2024Inventors: Abu Shohel Ahmed, Peter Robert Khello, George Zhou

Patent number: 10182053Abstract: Embodiments herein relate to a 3rd Generation Partnership Project, 3GPP, infrastructure node, a method in the 3GPP infrastructure node, 3GPP Access, Authorization, and Accounting, AAA server, a method in the 3GPP AAA server, a Home Subscriber Server, HSS and a method in the HSS. More particularly the embodiments herein relate to handling a UE requesting access to a service via an untrusted non-3GPP network. According to a first aspect, a method performed by a 3GPP node for handling a UE, requesting access to a service via an untrusted non-3GPP network is provided. The method comprises checking if trusted 3GPP network location information associated with the UE is available to the 3GPP node from a subscriber database or if the available trusted 3GPP network location information is obsolete.Type: GrantFiled: May 11, 2016Date of Patent: January 15, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Ping Chen, Vicente De Vega De La Red, Peter Robert Khello, Cristina Ruiz Balmaseda

Patent number: 9648019Abstract: The embodiments herein relate to a method performed by an AAA server (113) for enabling a non-SIM device (101b) to access a first network (100a) via a second network (100b). Based on a request for authorization to the first network (100a) from the non-SIM device (101b), the AAA server (113) obtains an identity associated with the non-SIM device (101b). The AAA server (113) transmits a request for a user profile associated with a user of the non-SIM device (101b) to the subscriber database (110). The request comprises the obtained identity for the non-SIM device (101b). The AAA server (113) receives, from the subscriber database (110), the requested user profile for the non-SIM device (101b). Based on the received user profile, the AAA server (113) authorizes the non-SIM device (101b) to access the first network (100a) via the second network (100b).Type: GrantFiled: April 15, 2015Date of Patent: May 9, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Robert Khello, Ping Chen, Pengbo Duan

Patent number: 9344923Abstract: The present invention is aimed to carry out an effective handover between a first and a second serving call control servers in order to fit suitable server capabilities for servicing a user, as well as to provide a mechanism whereby a subscriber server may upgrade the selection criteria for assigning the second serving call control server. Therefore, the present invention provides a new method and enhanced servers for re-assigning the second serving call control server, whereby the still ongoing sessions for the user in the first serving call control server are kept alive, and where a serving call control server is arranged to report towards the subscriber server what portions of a user profile are not understood or not supported at said serving call control server.Type: GrantFiled: August 13, 2004Date of Patent: May 17, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Miguel Angel Pallares Lopez, Evaristo Jose Camarero, Luis López Soria, Maria-Carmen Belinchon Vergara, Robert Khello

Patent number: 7027582Abstract: The present invention provides an efficient way of resolving telephone numbers and other entity/device identifiers into Internet addresses as well as accommodating portability of those telephone numbers and other entity/device identifiers without having to substantially modify or rework the domain naming system (DNS) infrastructure or established number portability schemes. Self-contained, additional functionality is implemented on a DNS server which allows smooth IP address resolution of telephone numbers or other entity/device identifiers by taking advantage of existing portability databases without impacting the existing networks that create and maintain such portability databases.Type: GrantFiled: July 6, 2001Date of Patent: April 11, 2006Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Robert Khello, Miguel Cobo, Victor Ferraro-Esparza, Antun Samukic

Patent number: 6839421Abstract: An efficient interface for service exchange is provided between a circuit-switched communications network and a domain naming system (DNS) in a packet-switched communications network. A node in the circuit-switched communications network receives from a first entity a request for a first service involving a second entity associated with a second entity identifier. A message is sent from the circuit-switched network node to a DNS server in the packet-switched network requesting a second service related to the second entity identifier. The result of the second service from the DNS server is used in providing the first service.Type: GrantFiled: October 29, 2001Date of Patent: January 4, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Victor Ferraro Esparza, Miguel Cobo, Robert Khello, Isabel Plata Andrés

Patent number: 6611584Abstract: In a telecommunication network a subscriber connected to an originating local exchange requests activation of a supplementary service. The supplementary service establishes an end-to-end TC-dialogue with a corresponding supplementary service of a destination local exchange. The TC-dialogue terminates the request on an interfering telecommunication service in an intermediate node. For preventing service operation failure in case of interaction between the supplementary service and the interfering telecommunication service, a relay link is established between an incoming TC-dialogue and an outgoing TC-dialogue at the intermediate node to realize a chain of end-to-end TC-dialogues between the originating exchange and the destination exchange, while using a transparent relay functionality independent of utilizing TCAP based supplementary service ASEs as intermediate nodes.Type: GrantFiled: October 26, 1999Date of Patent: August 26, 2003Assignees: Telefonaktiebolaget LM Ericsson, Telia AB, Koninklyke PTT Nederland N.V. respectivelyInventors: Robert Khello, Leslie Graf, Rune Boman, Pieter Veenstra

Patent number: 5742673Abstract: A generic service coordination mechanism solves feasible service interaction problems taking into account real-time processing constraints within telecommunication networks. The coordination mechanism limits service interaction complexity within an active basic call by preventing interactive service accessibility as early as possible following the request of a new service. Data defined on the basis of a general allocation, an individual subscriber allocation, and a service allocation is manipulated during provision and withdrawal, activation and deactivation, and invocation and operation of service procedures. Requests to initiate, read, change, or erase subscription and interaction data are processed internally according to a coordinator state machine. Requests are terminated by a response which includes a decision to continue basic call processing and service processing based on allocated services and encountered service interaction criteria such as restriction or dependency criteria.Type: GrantFiled: May 9, 1997Date of Patent: April 21, 1998Assignee: Telefonaktiebolaget LM EricssonInventor: Robert Khello
