| 20100027541 | EFFICIENT MBMS BACKBONE DISTRIBUTIONUSING ONE TUNNEL APPROACH - The present invention relates to a method, signal and devices for facilitating distribution of multimedia broadcast multicast services, i.e. MBMS, in a telecommunications network by receiving an MBSM session start message from a broadcast/multicast service center; sending control traffic on a control network; sending as control traffic to a serving node an MBMS session start request message and including a common tunnel end-point identifier, i.e. common TEID, in the MBMS session start request message; receiving information from the serving node indicating the acceptance of using IP multicast; and sending media content on an IP multicast backbone to hosts that have joined the multicast group using the common TEID. If any part of the communication network does not accept the IP multicast backbone as distribution method tunnels will be used between the gateway and serving node and between the serving node and control node. | 02-04-2010 |
| 20100272021 | METHOD, APPARATUSES AND PROGRAM FOR HANDLING PROTOCOL TRANSLATION BETWEEN EPS AND GPRS - The present invention relates to a solution for handling protocol translation issues in a mixed communication protocol network ( | 10-28-2010 |
| 20110090870 | ENHANCED SAE MOBILITY - The present invention relates to a solution for handling seamless handover between a 3GPP network and a non-3GPP network or two non-3GPP networks. The solution uses a new state information informing about a UE being in an Idle state in relation to the network not currently communicating through. Thus the UE is not immediately detached from the old network but may keep a logical connection and quickly re-attach to the old network if of interest. | 04-21-2011 |
| 20110128843 | FAILURE RECOVERY IN AN IP MULTIMEDIA SUBSYSTEM NETWORK - A method is provided for facilitating recovery from the failure of a P-CSCF within an IP multimedia Subsystem network. A gateway, such as a GGSN, monitors signals arriving at the gateway from the P-CSCF and provides an indication if the monitored signals become unacceptable, for example because of an interruption in the signals. The gateway responds by signalling the unavailability of the P-CSCF to user equipment, which was associated with the P-CSCF during a previous registration with the IMS network. In response, for example, the user equipment affected by the failure may request re-registration with the IMS network using a different available P-CSCF. | 06-02-2011 |

| 20090291666 | Charging Of GPRS Traffic For Roaming Mobiles By Performing Traffic Counting At The User Terminal - The application relates to charging of traffic from terminals and in particular of charging of traffic from GPRS mobile terminals which are roaming in a visited PLMN (not claimed). According to the applicant's acknowledged prior art, either the traffic passes the home PLMN or the Home Operator relies on the Visited Operator to generate the CDRs to be used by the Home Operator for billing. Whereas the first solution leads to tromboning and inefficient traffic routing, the second solution calls for a strong trust relationship between the Home and the Visited Operators. The present invention circumvents both problems in that the terminal generates a traffic counting information and sends it to the Visited Network. The Visited Network generates a traffic counting record comprising the traffic counting information from the terminal and traffic counting information from the Visited Network. The traffic counting record is subsequently sent to the Home Network. | 11-26-2009 |
| 20100202375 | Method for Reducing the Control Signaling in Handover Situations - The present invention relates to a method, devices, and a program for using IP multicast addresses for mobile terminals ( | 08-12-2010 |
| 20100246500 | GGSN PROXY FOR ONE TUNNEL SOLUTION - A method for roaming of a wireless mobile communication unit, a service support node and a proxy gateway support node for roaming between Public Land Mobile Networks, as well as a mobile communication infrastructure network arranged to handle roaming between different PLMN areas, where the support node is located in a current PLMN and arranged to send a context request to a first service support node in another PLMN for a user equipment, receive a context response from the first service support node, send a context acknowledgement to the first service support node, send an update location message to a home location register of the user equipment, receive a relocate PDP context response from the second proxy gateway support node and send a relocate PDP context request to a second proxy gateway support node in the current PLMN. | 09-30-2010 |

| 20080219218 | Gtp for Integration of Multiple Access - A network architecture comprising at least one core network, each core network comprising a number of packet data gateway access supporting nodes GASNs handling mobile user station access over an access network, said core network(s) further providing access to one or more global packet data communication networks (IN), and one or more nodes holding subscriber or mobile user station related information. The GASNs are further adapted to support intercommunication over a mobility protocol interface to, at reception of a request for change of access type from a mobile user station, establish information about the previous GASN of the mobile user station, and to, using the established information, update an established communication context concerning the mobile user station or create a new communication context concerning the mobile user station such that mobility between different access network types is enabled for a mobile user station without interruption of an ongoing session. | 09-11-2008 |
