Patent number: 9319242Abstract: A method includes receiving a request for establishing a communication pathway end-to-end over a network. The communication pathway includes a radio communication channel and a packet communication channel. The request identifies a plurality of traffic flows to be carried by the communication pathway and quality-of-service attributes associated with the traffic flows. At least one traffic flow is associated with at least one quality-of-service attribute determining the quality-of-service requirement for the at least one traffic flow. A quality-of-service is negotiated, based on the quality-of-service attribute, and the negotiated quality-of-service is reported.Type: GrantFiled: June 20, 2008Date of Patent: April 19, 2016Assignee: Nokia Technologies OyInventors: Tuija Hurtta, Ralitsa Gateva

Patent number: 7715339Abstract: Method and apparatus for dealing with a connection context request to establish a connection between a mobile station (MS) and a network gateway element. The gateway (such as a GGSN) determines whether binding information is required, then ascertains whether such information has been supplied. If the information is not supplied, the GGSN responds to the request on the basis of a policy determined by the operator of the network. This can include, for example, rejecting the request.Type: GrantFiled: March 28, 2003Date of Patent: May 11, 2010Assignee: Nokia CorporationInventors: Jorma Sarja, Ralitsa Gateva, Tuija Hurtta

Patent number: 7672317Abstract: A method, a system, and network elements for transmitting information between a user equipment and an IP packet gateway, are disclosed, the IP packet gateway communicating with an IP network via an interface, wherein, when the UE is requesting at least one service requiring access to the IP network, authorization of the requested service is checked, wherein an error message is sent from the IP packet gateway to the user equipment, when the requested service is not authorized. The present invention discloses several options of signaling error messages between IP packet gateway and UE, for example, via IP layer signaling (e.g. RESV ERR messages) or link layer signaling (e.g. IS2000 and IOS signaling). The solution according to the present invention, in particular, relates to a CDMA network in connection with an IP multimedia subsystem network.Type: GrantFiled: March 9, 2004Date of Patent: March 2, 2010Assignee: Nokia CorporationInventors: Ralitsa Gateva, Thinh Nguyen Phu

Patent number: 7391724Abstract: A system and method with policy control function (PCF) for multimedia broadcast/multicast system (MBMS) services that includes a core network, one or more application servers, and one or more policy control functions (PCF). In one embodiment, the core network includes one or more gateway GPRS support nodes (GGSN). One of the application servers provides a MBMS service. At least one policy control function is operatively connected between each GGSN and application server. MBMS session request information is sent from the MBMS service server to the policy control function. The policy control function provides authorization information for a MBMS session to the GGSN.Type: GrantFiled: May 16, 2003Date of Patent: June 24, 2008Assignee: Spyder Navigations, L.L.C.Inventors: Timo Alakoski, Jorma Sarja, Tuija Hurtta, Ralitsa Gateva
