Abstract: A method in a network node (103, 104, 111) for handling a request for an application to access a Wireless Local Area Network, WLAN (101), which application is run by a wireless device (114) and which application communicates in a cellular communications network (100). The network node (103, 104, 111) obtains traffic pattern information relating to the application, which traffic pattern information is derived from a deep packet inspection functionality of the cellular communications network (100). The network node (103, 104, 111) also obtains a decision whether to admit or refuse the request for the application to access the WLAN (101), which decision is based on the obtained traffic pattern information.

Abstract: A method, performed by a base station (100) in a GSM/EDGE Radio Access Network, GERAN, of providing traffic classification for a data traffic flow, related to a General Packet Radio Service, GPRS, or Enhanced General Packet Radio Service, EGPRS. The method comprises the step of the base station (100) obtaining (S1), for the data traffic flow, a traffic-class-based network layer Quality of Service, QoS, attribute for traffic prioritization. The method also comprises the step of the base station (100) including (S2) the traffic-class-based network layer QoS attribute in data packets of the data traffic flow to provide network-layer traffic classification for the data traffic flow.

Abstract: A network node for a GSM network, arranged to receive a TDMA frame comprising a plurality of timeslots, each of which comprises payload from one or more calls. The network node extracts payload from calls and to assigns the extracted payload a corresponding identifier identifying the call of the payload. The network node is also arranged to generate a data packet comprising the extracted payload from calls together with their corresponding identifier, and places the corresponding identifier in a header in the data packet. The network node is also arranged to transmit the data packet to another node in the GSM network.

Abstract: Handling of performance monitoring in a wireless communications system (100) comprising a transport network (150) relating to infrastructure for data transport in the wireless communications system (100). A management system (160) monitors (302, 401) one or more KPIs and detects (308, 402) that the monitored KPIs indicate a key performance degradation. Network elements (151-156) associated with the transport network (150), and those at least potentially are involved in causing the key performance degradation, are identified. The management system (160) sends one or more requests to the identified network elements (151-156). The one or more requests request the identified network elements (151-156) to perform performance measurements and report results thereof to the management system (160). The performance measurements comprise measurements regarding the transport network (150).

Abstract: A method is presented for connectivity checking and detection of connectivity failure, based on a modified Ethernet ARP address resolution mechanism to detect broken connectivity on physical, data-link and network layer between a first and a second node. The detection mechanism uses Periodical Gratuitous ARP messages (PGARP). PGARP messages are sent by a first node, the sender host or Issuer. On the other side of a data path is a second node, receiver host or Listener configured to detect lost connectivity by means of missing PGARP messages. The process on the Listener then informs subscribing services, host local, or remote, about the state of the connectivity.

Abstract: A technique for controlling transmission of layer-encoded media frames via a radio interface to a user terminal is presented. The layer-encoding defines a decoding-dependency of the media frames in terms of, for example, a base layer and one or more enhancement layers. A method implementation of the technique comprises receiving layer-encoded media frames at a radio access network and determining, at the radio access network, the decoding-dependency and a media frame play-out sequence of the received media frames. The method further comprises identifying, from the media frame play-out sequence, a media frame for transmission via the radio interface and determining that the identified media frame is unavailable. In such a case, at least one media frame dependent from the unavailable media frame is identified from the media frame decoding-dependency, and the at least one dependent media frame is excluded from transmission via the radio interface.

Abstract: A method is disclosed for use in a packet switched network, comprising carrying descriptor information relating to options for stream adaptation, for example media stream adaptation, in the packet switched network using at least one of the Next Step in Signalling, NSIS, and Resource Reservation Protocol, RSVP, signalling protocols. Carrying the descriptor information may comprise receiving (S120), processing (S130), generating (S110), distributing (S140), transmitting (S140) or using the descriptor information in any way. The method aims to provide a generally applicable solution for cross-layer information forwarding, with one realization of the general solution using the Layer Independent Descriptor as the forwarded information. Specific NSIS and RSVP object formats are also proposed.

Abstract: A method and arrangement in a wireless communication network for optimizing data rates when communicating layered multicast data. In an initial probing phase, the receiving capability of each user equipment (UE) in each cell is collected. The optimal data rate for each layer is then calculated and packets are transmitted to the UEs at the optimal rates. The UEs may periodically send updated receiving capabilities so that the optimal data rates can be updated. Additionally, the network may periodically obtain the updated receiving capabilities through secondary probing at unused data rates.

Abstract: In multimedia broadcast transmission a system a method and a device for improving transmission are provided. The optimization is achieved by the combination of a Virtual Time-Slice (VTS) solution within a broadcast service in which time-slice corresponding to a layered broadcast service and a feedback channel through a wireless access network. The VTS allows the system to set the layer content within a broadcast service time-slice according to the user's feedbacks. An optimization algorithm selects the appropriate number of enhancement layers mapped into VTSs. The users provide feedback information based on their own receiving capabilities or on subscription limitations. If a time-division multiplex multimedia broadcast network, e.g. DVB-H network is deployed next to the wireless access network, e.g. a 3G network, then these feedback information can be signaled via this network.
