| 20090219848 | PROVISION OF MULTIMEDIA BROADCAST/MULTICAST SERVICE (MBMS) FOR ROAMING SUBSCRIBERS - The present invention proposes a solution for providing multicast/broadcast service to users roaming between different operational domains. In particular it is proposed to provide means enabling the user to contact a home multicast/broadcast server Said means might be a request being triggered by the user Said request includes a network identifier identifying the visited operational domain, which is provided to the multicast/broadcast server The latter decides on a provision method for providing the at least one multicast/broadcast service to the user in the visited operational domain considering rules for a provision of multicast/broadcast services in the visited operational domain and the request triggered by the user Further the multicast/broadcast server determines a second parameter set for accessing the at least one multicast/broadcast service in the visited operational domain according to the provision method and informs the user about the second parameter set. | 09-03-2009 |
| 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 |
| 20100325515 | CONTROLLING POINT-TO-MULTIPOINT TRANSMISSIONS OF CONTENT DATA OVER A RADIO INTERFACE - The invention relates to error control for point-to-multipoint (PTM) transmissions of content data over a radio interface. A method embodiment for controlling a PTM transmission in a PTM-enabled network comprises the steps of receiving and storing redundancy data at a dedicated redundancy data storage in a radio access network, wherein the redundancy data are provided for a correction of transmission errors in the content data resulting from the transmission of the content data without the redundancy data over one or more radio interfaces; receiving a request for redundancy data from a redundancy data control node; and responding to the redundancy data request by providing at least a portion of the redundancy data. | 12-23-2010 |
| 20110085489 | SAE APPLICATION FOR MBMS - The present solution relates to a method in a first core network gateway ( | 04-14-2011 |
| 20110090792 | ARRANGEMENT AND METHOD RELATING TO HANDLING OF IP TRAFFIC - The present invention relates to an arrangement for controlling communication of data packets through one or more communication networks or network domains. It comprises means for identifying real-time or non-bursty data packet traffic, for separating real-time data packet traffic from bursty data packet traffic, for controlling the admission of real-time data packets and it further comprises or communicates with means for keeping information about the amount of real-time data packet flows that is admissible and for keeping information about current number of admitted and/or non-admitted real-time data packet flows. Means are also provided for establishing whether a packet or packets of a real-time data packet flow is/are admitted or not, such that generally all packets of a real-time IP data packet flow either can be admitted or rejected. | 04-21-2011 |
| 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 |
