Abstract: For enabling differentiated handling of mobile network data traffic between a UE (410) and a network resource, a network address lookup procedure is adapted on the basis of mobile access information related to a connection between the UE (410) and a mobile network. The mobile access information may be obtained from authentication traffic (502, 503, 504, 505) in the mobile network and be provided to a node (560) performing the adaptation by modifying a message (508) of the lookup procedure. On the basis of the mobile access information, the adaptation may cause the lookup procedure to return a network address of a replacement network resource capable of handling the data traffic. The network address of the replacement network resource (60) matches a packet filter for directing the data traffic to a bearer established between the UE (410) and the mobile network.

Abstract: A method for specifying the quality of service in a transmission of data packets between a service entity (AF1) and a user equipment over a mobile network is described. The mobile network comprises a core network node (SGSN1) and an access node (NB1, RNC1) which are adapted to control the handling of data packets sent between the service entity (AF1) and the user equipment (UE1). A plurality of service classes relating to the quality of service are preconfigured and a selected service class is selected from said plurality for the transmission. A first transmission context (PDP1) is established between the core network node and the user equipment (UE1), said first transmission context being associated with a first set of attributes for defining a first quality of service for the exchange of the data packets with the user equipment in the transmission.

Abstract: The invention relates to a content delivery entity (100) configured to deliver a first data traffic from a first Internet content provider (310) to a mobile user equipment (200) via an access network of a mobile communications network. The entity (100) comprises an interface (113) configured to detect the first data traffic that shall be treated with priority. An acceleration unit (120) is configured to accelerate the delivery of the first data traffic from the first Internet content provider to the content delivery entity, and a controller (110) is configured to forward the first data traffic from the first Internet content provider (310) to the mobile user equipment (200) in the access network in such a way that the first data traffic from the first Internet content provider (310) is routed to the mobile user equipment (200) in the access network with a priority different from that of a second data traffic that is delivered from a second Internet content provider (330, 390) through the access network.

Abstract: Differentiated Handling of Data Traffic with Adaptation of Network Address Lookup In a method of differentiated handling of data traffic, the data traffic is related to a network resource and is preceded by a lookup procedure for obtaining a network address of the network resource. A message of the lookup procedure is processed for adapting the lookup procedure. Due to the adaptation, the lookup procedure returns a network address of a replacement network resource. The replacement network resource is capable of replacing the network resource in communication of data packets of the data traffic. On the basis of the network address of the replacement network resource, differentiated handling of the data packets in said communication with the replacement network resource is accomplished.

Abstract: A method in a communications network for adaptive handling of network data traffic between a user equipment and a network resource, said data traffic being enabled by a lookup procedure for obtaining a network address of the network resource. The user equipment sends to a server a request for accessing said data traffic. The server obtains access information related to a connection of the user equipment to the communications network and sends a further request to a lookup adaptation server. The source address of the further request is based on the access information. Based on the source address of the further request, the lookup adaptation server returns to the user equipment a network address of the network resource capable of handling the data traffic.

Abstract: The present invention relates to a partitioning entity and a method for partitioning capacity in a communication network to avoid starvation of certain data traffic and to support services with different characteristics. The method of partitioning capacity comprises assigning communication links to a group associated with a time-varying group capacity to form a group of communication links. The group comprises a first sub-group and at least a second sub-group of communication links. Further, the method comprises allocating a non-zero fraction of the time-varying group capacity to the first sub-group of communication links of the group.

Abstract: A system and method for specifying the quality of service in a transmission of data packets between a service entity and a user equipment is provided. A plurality of service classes relating to the quality of service are preconfigured and a selected service class is selected. A first transmission context, associated with a first set of attributes, is established between a core network node and the user equipment. A second transmission context, associated with a second set of attributes, is established between an access node and the user equipment. The selected service class is specified by a third set of attributes, which is forwarded to the core network node and the access node. The third set of attributes is used to determine the first set of attributes and/or the second set of attributes.

Abstract: For event reporting between a first node and a second node of a mobile telecommunications network, the second node sends an indication to the first node to subscribe to reporting of a certain event type by the first node. The indication may specify that a change in type of radio access technology, as used by a user equipment for connecting to the telecommunications network, is to be reported from the first node to the second node. The second node may provide additional information to the first node to further specify a subtype of the event to be reported. The additional information may specify at least one type of radio access technology. Based on detecting the event of the specified event type and subtype, e.g., a change to or from a specific type of radio access technology, the first node sends a report of the detected event to the second node.

Abstract: In order to allow efficient differentiated handling of network traffic in a network section, a network address translator performs network address translation on incoming data packets to be transmitted into the network section and/or on outgoing data packets transmitted from the network section. In the incoming data packets, the network address translation replaces a source network address with a replacement network address. In the outgoing data packets, a replacement network address is included in place of a destination address, and the network address translation replaces the replacement network address with the destination network address. In each case, the replacement network address is selected according to a traffic class of the data packet. In the network section, differentiated handling of the data packets on the basis of the replacement network address is provided.

Abstract: Data packets of a flow associated with a first bearer and data packets of a flow associated with a second bearer are received in an intermediate node (140). The data packets are then transmitted from the intermediate node (140). in response to a congestion being detected on the first bearer, one of the first bearer and the second bearer is selected for notification of the congestion in the associated flow. The selection may be based on a type of the congestion, e.g. the detected congestion being in a transport network (160) or the congestion being on a radio link (250).

Abstract: A policy controller (30) of a mobile network receives an authorization request (302) for a packet-based service from a node (80). In response to receiving the authorization request (302), the policy controller performs an authorization check (305) to determine an authorization status of the service and sends an authorization response (306) to the node (80). The authorization response (306) indicates the authorization status of the service. In response to the same authorization request (302), the policy controller (30) performs at least one further authorization check to redetermine the authorization status of the service. If the further authorization check indicates that the authorization status of the service has changed, the policy controller (30) sends a status change message (311) to the node. The status change message (311) indicates to the node (80) that the authorization status of the service has changed.

Abstract: In a mobile communication network, data traffic is mapped to a non-guaranteed bit rate bearer (50, 60) established between a gateway node (100) and a mobile terminal (200). The non-guaranteed bit rate bearer comprises a first sub-bearer (51, 61) between the mobile terminal (200) and an access node (120), a second sub-bearer (52, 62) between the access node (120) and an intermediate gateway node (110), and a third sub-bearer (53, 63) between the intermediate gateway node (110) and the gateway node (100). Releasing of the third sub-bearer (53, 63) is controlled on the basis of the first sub-bearer (51, 61) and/or the second sub-bearer (52, 62) being released.

Abstract: A method of controlling a radio access network entity of a data unit communication network is described, said radio access network entity being involved in providing a transport service to a radio terminal of said data unit communication network, said transport service being characterized by a set of values associated with respective service quality parameters, said method comprising: monitoring (S30) a communication quality at the radio access level of a communication between said terminal and an access point of said radio access network, and setting (S31) a congestion indication marking in data units of said transport service if said communication quality fulfils a radio communication degradation condition.

Abstract: A network entity comprising a processing unit that is configured: to receive a policy token from user equipment (S10) to determine network equipment handling a packet flow to the equipment (S30); to generate an instruction to apply a specific policy for the packet flow to the user equipment based on received policy token (S40); and to send the instruction to the network equipment (S50).

Abstract: In a mobile communication environment, the data traffic is mapped to a number of bearers. In a downlink direction, this is accomplished by filtering data packets on the basis of an identifier which is included into the data packets in response to packet inspection. In the uplink direction, a mirroring function is applied which detects incoming data packets, which are received on one of a plurality of bearers and have a first identifier, and outgoing data packets having a second identifier which is complementary to the first identifier. The outgoing data packets having the complementary second identifier are routed to the same bearer from which the incoming data packets are received.

Abstract: A node (36?; 50) generates messages to be sent to a policy controller (30). Further, the node (36?; 50) determines a load value. The load value represents a number of the messages which are sent from the node (36?; 50) to the policy controller in a given time interval. In response to the load value reaching a threshold, the node (36?; 50) limits sending of at least one of the messages to the policy controller.

Abstract: User identity token for identifying a user of a communication network A first node (13), e.g., a policy controller of a communication network, receives a request (101) from a second node (15), e.g., an application server for providing a service in the communication network. The request (101) includes a transport address assigned to a user of the communication network. Further, the first node (13) accesses mapping data (31) relating the transport address to a subscription identity of the user and determines a user identity token which is mapped to the subscription identity of the user and masks the subscription identity. The first node (13) then sends a response to the second node (15). The response (102) includes the user identity token.

Abstract: The present invention relates to a methods and network nodes for controlling resources of a service session in a communication network as well as to a corresponding system and computer program to improve the handling of resources in the network, and particularly to optimize signaling in the network. The method for controlling resources for a service session by a policy and charging system in a communication network comprises the steps of obtaining, at a first network node, a request including service session data indicating the type of service; determining, based on the service session data obtained at said first network node, a resource type to be assigned to said service; and sending to a second network node an indication of said resource type assigned to said service, according to which resource type it is determined when a service session associated with said service is terminated.

Abstract: In a mobile communication network, data traffic of a certain quality of service class is forwarded in accordance with a traffic forwarding policy associated with this quality of service class, e.g. by establishing dedicated bearers (52, 54). For implementing energy control, an energy control attribute is assigned to the quality of service class. On the basis of the energy control attribute, a data throughput for forwarding the data traffic is limited to a maximum limit. This may be accomplished by using a throughput limiter (150, 250) in one or more nodes (100, 110, 120, 200) participating in the transport of the data traffic.

Abstract: For handling user plane traffic in a communication network, a NAT node (100) determines a mapping between a network address (200-e) of a server (200) and a replacement network (200-i) address matching a packet classification rule implemented in the communication network. If the NAT node (100) receives an UL data packet (403) in which a source address identifier corresponds to a network address of a user equipment (10) and a destination address identifier corresponds to the replacement network address (200-i), it performs NAT of the UL data packet (403) in accordance with the mapping. This is accomplished at least by modifying the destination address identifier in the UL data packet (403) to correspond to the network address (200-e) of the server (200). The NAT node (100) then sends the modified UL data packet (405) toward the server (200).
