For efficiently handling network traffic via a fixed access, classification of UL data traffic in a communication device may be accomplished in a reflective mode by detecting identifiers of outgoing uplink data packets which are complementary to identifiers of incoming downlink data packets. The downlink data packets are already assigned to the traffic classes. The outgoing uplink data packets carrying the complementary identifier are assigned to the same traffic class as the incoming downlink data packets. For this purpose, the communication device is provided with a traffic classificator. In the reflective mode, the traffic classificator locally generates uplink packet classification rules by monitoring received downlink data packets.

Handling network traffic via a fixed access

To handle network traffic, a Deep Packet Inspection (DPI) node receives, from a Policy and Charging Rules Function (PCRF) network node, packet inspection control data that maps a specific service to an identifier. The DPI node identifies that a data packet pertains to the specific service. The identifying comprises performing DPI on at least a data section of the data packet. The DPI node notifies the PCRF network node that the DPI node received the data packet and that the data packet pertains to the specific service. The DPI node marks the data packet with the identifier in accordance with the packet inspection control data received from the PCRF network node.

Techniques for handling network traffic

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.

Methods and network nodes for controlling resources of a service session as well as corresponding system and computer program

A service class for a transmission of data packets between a service entity and a user equipment is selected from a plurality of service classes. A first transmission context is established between a core network node and the user equipment, and is associated with a first set of attributes for defining a first quality of service for the transmission. Furthermore, a second transmission context is established between an access node and the user equipment, and is associated with a second set of attributes for defining a second quality of service for the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node.

Method and devices for specifying the quality of service in a transmission of data packets

A user equipment receives incoming data packets from one of a plurality of bearers. The incoming data packets comprise a first identifier indicating a source. The user equipment also detect outgoing data packets which include a second identifier indicating the source of the first identifier as destination of the outgoing data packet. The user equipment routes detected outgoing data packets which include the second identifier to the same bearer from which the incoming data packets having said first identifier are received. The detecting and routing is selectively activated on the basis of a control signal.

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.

For efficiently handling network traffic via a fixed access, classification of UL data traffic in a communication device () may be accomplished in a reflective mode by detecting identifiers of outgoing uplink data packets which are complementary to identifiers of incoming downlink data packets. The downlink data packets are already assigned to the traffic classes (). The outgoing uplink data packets carrying the complementary identifier are assigned to the same traffic class () as the incoming downlink data packets. For this purpose, the communication device () is provided with a traffic classificator (). In the reflective mode, the traffic classificator () locally generates uplink packet classification rules () by monitoring received downlink data packets.

An application executed on a plurality of wireless communication devices () measures a performance indicator. The application sends reports () of the performance indicator to a server (). On the basis of the reports (), the server determines a rate of reporting the performance indicator and sends an indication () of the rate of reporting to the application executed on at least some of the wireless communication devices (). According to the indicated rate of reporting, the application on these wireless communication devices controls a timing of measuring the performance indicator and sending the reports () to the server ().

Rate control for application performance monitoring

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

Limitation of signaling messages to a policy controller of a network

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.

Selective event reporting in a mobile telecommunications network

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.

Method and device for an adaptive handling of data traffic

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.

For transmitting data between a node () of a mobile network and a further node (), the further node sends downlink data packets to the node () of the mobile network. The downlink data packets carry a destination address corresponding to a user equipment () connected to the mobile network. For implementing an inband data channel between the node () of the mobile network and the further node (), the further node () inserts data destined to the node () of the mobile network into at least one of the downlink data packets and marks this downlink data packet as including data destined to the node () of the mobile network. The node () of the mobile network receives the downlink data packets from the further node () and identities, on the basis of the marking, the least one downlink data packet including data destined to the node () of the mobile network. The node () of the mobile network then extracts the data from the identified downlink data packet. A corresponding inband data channel may also be used in the uplink direction.

Transmission of data to or from a node of a mobile network

A policy controller of a mobile network receives an authorization request for a packet-based service from a node. In response to receiving the authorization request, the policy controller performs an authorization check to determine an authorization status of the service and sends an authorization response to the node. The authorization response indicates the authorization status of the service. In response to the same authorization request, the policy controller 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 sends a status change message to the node. The status change message indicates to the node that the authorization status of the service has changed.
