Publication number: 20220294697Abstract: Embodiments include methods for a network node in a wireless network to manage network resources. Such methods include mapping one or more application-level performance requirements to one or more network performance requirements. The mapping can be based on a Markov chain model and the application-level performance requirements can be associated with an application hosted by one or more user equipment (UEs) served by the wireless network. Such methods include, based on the network performance requirements, configuring at least one of the following for data transmission and/or reception associated with the application: the one or more UEs, and respective serving cells for the one or more UEs. Other embodiments include operations such as mapping one or more network performance parameters to one or more application-level performance metrics based on a Markov chain model, and monitoring whether the application-level performance metrics fulfill corresponding application-level performance requirements.Type: ApplicationFiled: October 29, 2020Publication date: September 15, 2022Inventors: Milad Ganjalizadeh, Abdulrahman Alabbasi, Juan-Antonio Ibanez, Marina Petrova, Jens Zander

Patent number: 10985896Abstract: There is disclosed a method and a network node for handling signals transmitted from one or more wireless devices in a wireless network when Time Division Duplex (TDD) is employed such that two successive uplink subframes of a radio frame are separated by an intermediary time interval. The signals are received during a subframe reserved for uplink transmissions, and a sending time interval with a length of at least a subframe is selected. Then, the received signals are sent to a transport network such that the signals are distributed over the selected sending time interval instead of being sent virtually at the same time as in conventional procedures. Thereby, the signals will be distributed over a longer time when arriving at the transport network which will have time to handle the signals properly such that any loss of packets can be avoided or at least reduced.Type: GrantFiled: January 13, 2016Date of Patent: April 20, 2021Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Patrik Rask, Juan-Antonio Ibanez

Patent number: 9231841Abstract: For maintaining a certain quality of service for a certain type of data traffic, the data traffic may be directed to a corresponding bearer established with respect to a user equipment. By sending probe packets on the bearer and/or on a further bearer and receiving a response packets returned in response to the probe packets, a parameter corresponding to a time period between sending a probe packet and receiving the corresponding response packet can be measured. On the basis of the measured parameter, a bearer control procedure with respect to the user equipment is initiated. This bearer control procedure may for example include directing data packets of selected data traffic from one bearer to another bearer, modification of at least one quality of service parameter of a bearer, and/or establishing or releasing a bearer.Type: GrantFiled: July 8, 2011Date of Patent: January 5, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Juan-Antonio Ibanez, Per Willars

Patent number: 7103002Abstract: Methods of re-establishing a connection between a radio network node and a core network having a control plane entity and a user plane entity in a communication network and of detecting faulty communication paths or re-started entities in such networks are provided. A control-plane entity sends an event in accordance with a media gateway control protocol to the user-plane entity that orders the user-plane entity to notify the control-plane entity when user-plane traffic is received from another network node or when a faulty path or re-started peer is discovered. In response to an order by the control-plane entity, a connection between the radio network node and the user-plane entity can be re-established. Heartbeat messages and heartbeat acknowledgment messages are sent through a communication path, and if a heartbeat acknowledgment message has not been received, the control-plane entity is notified of the faulty path.Type: GrantFiled: July 11, 2001Date of Patent: September 5, 2006Assignee: Telefonktiebolaget LM Ericsson (publ)Inventors: Frode Bjelland, Juan-Antonio Ibanez

Patent number: 6973054Abstract: A method in a communication system of transferring control of a user-plane entity from a first control-plane entity to a second control-plane entity is provided. The user-plane entity sends a set of identifying parameters to the first control-plane entity, which subsequently sends the set of identifying parameters to the second control-plane entity. The second control-plane entity determines if it can control the user-plane entity. If the second control-plane entity can control the user-plane entity, then the second control-plane entity sends an indication to the user-plane entity that a change in control-plane entities has occurred and that at least some resources of the user-plane entity that were controlled by the first control-plane entity are to be controlled by the second control-plane entity. The resources may be allocated to a mobile terminal and the change in control entity may be the result of a change in location of the mobile terminal.Type: GrantFiled: November 28, 2001Date of Patent: December 6, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Frode Bjelland, Stephen Terrill, Juan-Antonio Ibanez

Patent number: 6879820Abstract: A method of facilitating charging for communication in a telecommunication network, such as a network supporting GPRS, that has a node split into a control-plane entity and a user-plane entity includes the step of sending, from the control-plane entity to the user-plane entity, an event in accordance with a media gateway control protocol. The event orders the user-plane entity to notify the control-plane entity when a predetermined volume of communication has occurred. The method further includes the steps of determining, by the user-plane entity, whether the predetermined volume has occurred, and notifying the control-plane entity when that has occurred. The predetermined volume may be a number of octets, and the user-plane entity may notify the control-plane entity by sending a notify command in accordance with the media gateway control protocol.Type: GrantFiled: July 11, 2001Date of Patent: April 12, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Frode Bjelland, Juan-Antonio Ibanez

Publication number: 20030026230Abstract: A system, method, and apparatus for duplicate address detection in a communication network includes a plurality of communication nodes and a proxy node. A particular one of the communication nodes generates a tentative interface address and transmits a solicitation message including the tentative interface address to the proxy node. After receiving the solicitation message, the proxy node determines from the solicitation message whether the tentative interface address is allocated to another of the communication nodes. If the proxy node determines that the tentative interface address has been allocated to another communication node, the proxy node sends a response message to the particular communication node.Type: ApplicationFiled: August 20, 2001Publication date: February 6, 2003Inventors: Juan-Antonio Ibanez, Vidar Oliver Lilleheim, Hesham Soliman, Bernard Volz
