Patent number: 11539761Abstract: Embodiments herein relate to a method performed by an IMS node for handling data of a UE, in a communication network, wherein the communication network comprises partitioned sets of functionalities of one or more core networks wherein each set of functionalities belongs to a network slice. The IMS node receives, from the UE, a message for registering the UE to the IMS node, wherein the message comprises a slice indication indicating a network slice identity and a UE indication identifying the UE. The IMS node stores a registration of the UE in the IMS node, in addition to a previously stored registration of the UE, with the proviso that the indicated network slice identity differs from a previous network slice identity of the previously stored registration of the UE and thereby allowing parallel active communications using the registration and the previously stored registration.Type: GrantFiled: December 10, 2018Date of Patent: December 27, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Charles Hegarty, Timo Forsman, Mats Ola Stille

Patent number: 10003619Abstract: A method of handling SIP session initiation requests in an IP Multimedia Subsystem, IMS, network. The method is performed at an application server, AS, within the network. The AS receives a session initiation request containing a destination address, where that destination address is currently associated with a plurality of registered User Equipments, UEs. The AS then determines whether or not a UE associated with the destination address, is already involved in a session. If so, the AS causes the session initiation request to be forwarded only to that UE. If not, the AS causes the session initiation request to be forwarded to all UEs registered in respect of the address.Type: GrantFiled: December 20, 2013Date of Patent: June 19, 2018Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Mats Ola Stille, Jan Holm

Patent number: 8964961Abstract: A method of routing a session from a calling party in a serving communication network of the calling party to a called party is described. The serving communication network of the calling party is distinct from a home communication network of the calling party. The method is executed by a session routing node in the serving communication network of the calling party. In order to optimize a session routing path of signaling data of the session, the method comprises receiving from the home communication network of the calling party a session routing request requesting routing the signaling data of the session to the called party via the serving communication network of the calling party, and routing the signaling data of the session to the called party via the serving communication network of the calling party based on the received session routing request.Type: GrantFiled: January 24, 2011Date of Patent: February 24, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Ralf Keller, Fredrik Lindholm, Gert Öster, Mats Ola Stille

Patent number: 8824479Abstract: Method and apparatus in a user terminal (200) for controlling the admission of outgoing communications. One or more communication admission rules (206a) are created locally in a communication admission controller (206) in the terminal, according to configuring input commands dictating when outgoing communications should be admitted or rejected. When an input unit (202) receives an input request from a current terminal user for an outgoing communication, the communication admission rules are checked. A communication request unit (210) sends a communication request message towards a used communication services network if the requested outgoing communication can be admitted according to the communication admission rules. Otherwise, a reject message is provided to the current terminal user.Type: GrantFiled: November 13, 2008Date of Patent: September 2, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Mats Ola Stille

Publication number: 20140160992Abstract: A method and arrangement for providing a ring-back presentation to a calling terminal after receiving a call setup request from the calling terminal for a first communication session with a called terminal. A second packet-based communication session is established with the calling terminal, independent of the first session, and pre-defined media content is provided as said ring-back presentation to the calling terminal over the second session. Thereby, ring-back presentations to waiting callers can be selected from a great range of media types, including visual media. A calling user can also control the playout or display of the ring-back presentation irrespective of when the call is answered.Type: ApplicationFiled: February 12, 2014Publication date: June 12, 2014Applicant: Telefonaktiebolaget L M Ericsson (PUBL)Inventors: Mats Ola Stille, Jan Hultkrantz, Ulf Olsson

Patent number: 8295207Abstract: A system and method for handling multimedia conference calls in a telecommunication network. To determine the capabilities of the other terminals in a group, a first terminal sends a query message to a group server. The group server sends further query messages to the other terminals and collects their responses containing their capabilities. The group server analyzes the capabilities to determine a common set of capabilities. The group server then sends the common set of capabilities in a response to the first terminal.Type: GrantFiled: May 9, 2008Date of Patent: October 23, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mats Ola Stille, Jan Holm

Publication number: 20110092172Abstract: A method of sending a communication to a Participant in a PoC Group Session. A PoC client sends a SIP REFER message to a PoC participating Server, which forwards it to a PoC Controlling Server. The SIP REFER message comprises an identity of a target Participant in the Group Session and a message content. The PoC Controlling Server creates a SIP MESSAGE method, the MESSAGE addressed to the target Participant and including the message content. The SIP MESSAGE is then sent to a target Participating Server that serves the target Participant. In this way, the PoC client can send private message content via the PoC Controlling Server to another Participant in a PoC Group Session without sending it to all Participants.Type: ApplicationFiled: June 9, 2008Publication date: April 21, 2011Inventors: Mats Ola Stille, Jan Holm

Patent number: 6775534Abstract: There is described a system which, in a voice over IP radiotelecommunications system, allows a mobile station to make an emergency call, even though other calls would not be allowed at that time. The mobile station includes an emergency call indication in the session activation request, and this is recognized by the network nodes, which then allow call set up.Type: GrantFiled: April 13, 2001Date of Patent: August 10, 2004Assignee: Telefonaktiebolaget LM EricssonInventors: Hans Åke Lindgren, Mats Ola Stille

Patent number: 6205328Abstract: Methods and systems for signalling between a mobile station and a network for requesting supplementary services are disclosed. The network implicitly assumes that signals from a mobile station relate to either a held or active call or that a second action is required after the requested action is performed so that the complexity of the mobile unit can be reduced.Type: GrantFiled: April 25, 1996Date of Patent: March 20, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sven Jörgen Lantto, Mats Ola Stille
