Patent number: 9184978Abstract: A call to a dual mode user equipment is handled by using a further access network from cellular telecommunications access network. An indication of an incoming call to the user equipment is received in a control node that the device can be reached via a device using session initiation protocol (SIP) via the cellular telecommunication access network. The device using SIP sends messages to a device that transforms messages sent according to call control signaling protocol used in the cellular telecommunications network into messages according to SIP. A route to the SIP device is linked to a device that transforms user plane according to protocol in the cellular telecommunications access network into user plane according to internet protocol and vice versa.Type: GrantFiled: September 28, 2004Date of Patent: November 10, 2015Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Joerg Christian Ewert, Ralf Keller, Andreas Witzel, Martin Stumpert

Patent number: 9148451Abstract: The present invention is directed to a method, a switching server, a terminal device and system for providing circuit switched calls and services to terminal devices connected to a switching server via an IP Multimedia Subsystem. The method comprises a step of providing (S120) a first interworking entity (330) in the terminal device (300) for interworking between circuit switched signalling messages and signalling messages related to packet switched sessions towards the IMS (30). The method further comprises providing (S130) a second interworking entity (230) in the switching server (200) towards the IMS (30). The terminal device (300) is thus capable of accessing circuit switched calls and services directly from the switching server (200).Type: GrantFiled: November 24, 2008Date of Patent: September 29, 2015Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Ola Melander, Joerg Christian Ewert

Patent number: 8989151Abstract: The application relates to SMS over LTE radio access. Several alternatives are already known, such as specified in 3GPP TS 24.247 which supports text messaging capabilities and 3GPP 23.204 which supports all existing SMS capabilities through SMS encapsulation in IP. Furthermore, 3GPP 23.272 which relates to SMS in CS fallback. A further technique is known as Generic Access Network which is under study in 3GPP 23.879 relating to CS domain services over evolved PS access and in Voice Over LTE VOLGA. The present application provides a solution for handling messages between legacy networks in the form of circuit-switched networks and IP network architecture in the form of an IP Multimedia Subsystem IMS while minimizing the efforts needed for system integration by maximal reuse of existing functionalities.Type: GrantFiled: December 23, 2009Date of Patent: March 24, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Joerg Christian Ewert, Ralf Keller, Andreas Witzel

Patent number: 8738799Abstract: The invention relates to a technique for selecting a framing format to be used for communications on the user plane of a layered communications network. The selection technique includes the provision of a first user plane component (such as a media gateway, MGW) bridging transmission regimes and operable in accordance with two or more different framing formats. The first user plane component is controllable via control messages received from a control plane without being responsive to any framing format instructions possibly included in the control messages. The first user plane component or any other user plane equipment in communication with the first user plane component selects the framing format to be used for user plane communications. The selected framing format is then implemented by the first user plane component for communications with a second user plane component.Type: GrantFiled: February 7, 2005Date of Patent: May 27, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Joerg Christian Ewert, Martin Stümpert

Patent number: 7764623Abstract: To enhance quality of service management in support of application sessions running on top of bearer services, according to the present invention it is suggested to, firstly, execute a bearer service analysis in support of automatic quality of service class management. Heretofore, a bearer service carrying packet switched service traffic in support of an application session is analyzed for identification of different types of services by the application session. Related analysis information derived at an analysis unit 10 is then forwarded to a quality of service management unit 16, which is adapted to automatic quality of service class management. In particular, the quality of service management unit 16 determines and manages a quality of service class according to the identified quality of service class as forwarded by the bearer service analysis unit 10.Type: GrantFiled: February 1, 2005Date of Patent: July 27, 2010Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventors: Martin Stumpert, Joerg Christian Ewert
