A wireless communication device may detect, within a specified time duration, at least a specified number of occurrences of a sequence of events, which includes the wireless communication device transitioning from a second cellular network operating according to a second radio access technology (RAT) to a first cellular network operating according to a first RAT, the wireless communication device failing to remain on the first cellular network for more than a specified time duration, and the wireless communication device returning from the first cellular network to the second cellular network. At least in response to this detection, the wireless communication device may determine whether to attempt future transition to the first cellular network while operating in the second network, based on one or more conditions, and/or may adjust one or more parameters used by the wireless communication device to determine when to redirect from the second cellular network to the first cellular network.

Data migrations are not able to be identified or traced through a switched network to their originating hub, because the corresponding TCP/IP data stream goes through a plurality of optimized differential switches and the originating IP in the packet header gets replaced at each switch. The present invention provides a mechanism to introduce a lag or a jitter into the IP to label the migrated data. The labeled data are able to be traced and identified through multiple managed hubs and/or switches.

A method in a Gateway General packet radio service Support Node, GGSN, for transferring a service identifier from a packet core network to a radio network is provided. The GGSN adds a service identifier in a General packet radio service Tunneling Protocol for User Plane, GTP-U, header extension of a data packet. The service identifier comprises information about what service and/or traffic pattern that the packet concerns. The GGSN sends the data packet with the GTP-U header extension to a radio network.

Apparatus and methods are disclosed for implementing bandwidth throttling to regulate network traffic as can be used in, for example, vulnerability scanning and detection applications in a computer network environment. According to one embodiment, a method of routing network packets in a networked device having plural network interfaces combines applying traffic class and network interface throttling for marking network packets with a differentiated service code based on input received from a profiler application, throttling the bandwidth of network packets based on a threshold for a designated network interface for the packet, throttling the bandwidth of the bandwidth-throttled packets based on a threshold for its respective differentiated service code, and emitting network packets on each respective designated network interface.

Embodiments of the present invention include systems and methods for providing Quality of service to RFID. In one embodiment the present invention includes a method of providing quality of service in an RFID network comprising storing RFID priority information corresponding to the RFID network, wherein the RFID network comprises one or more tags and one or more readers mapping the RFID priority information into priority information corresponding to a second network.

The present invention relates to embodiments of nodes and methods in a node in a data telecommunication network. The method and embodiments thereof enables control of data packet traffic belonging to different access technologies to be sent with the same Quality of Service class over an aggregated encrypted Internet Security tunnel, IPsec tunnel. The received data packets are encrypted and encapsulated as payload in an IP data packet to be sent over an aggregated encrypted IPsec tunnel, which header is marked with an access technology index comprising a code for the identified access technology of the one or more received data packets encrypted and encapsulated as payload in the IPsec tunnel and a hash identifier code enabling enhanced scheduling and routing.

There is provided mechanisms for transmission of packets over a TSN aware network. A method is performed by a network node. The method includes obtaining a traffic flow of packets from a non-TSN aware network interface. The method includes extracting, from the packets and at above OSI protocol layer 2, information indicative of which traffic class the traffic flow belongs to. The method includes mapping the traffic class to a TSN traffic class or priority. The method includes associating the packets with an indicator of the TSN traffic class or priority. The method includes providing the traffic flow of packets, including the indicator, to a TSN aware network interface for transmission of the packets over the TSN aware network.

Embodiments provide a method for transmitting a service stream in a flexible Ethernet and an apparatus. The method includes: obtaining a to-be-transmitted service stream, where the service stream is to be transmitted by using a target virtual connection supported by a physical connection group between a transmit end and a receive end, the physical connection group includes multiple physical connections and supports at least one virtual connection, and the target virtual connection is any one of the at least one virtual connection; determining, from total bandwidth resources of the multiple physical connections and according to timeslot configuration tables used by the multiple physical connections, a timeslot bandwidth resource that belongs to the target virtual connection; and transmitting the service stream to the receive end by using the timeslot bandwidth resource that belongs to the target virtual connection.

A method for operating a device in a wireless communication system is provided. The method includes receiving a plurality of embedded subscriber identity module (eSIM) profiles, each eSIM profile being associated with at least one quality of service (QoS) feature, performing a primary mapping between the plurality of eSIM profiles and applications available on the device based on QoS requirements of the applications, and performing transfer of data belonging to the applications using the mapped eSIM profiles corresponding to the primary mapping.

A method of managing default QoS rules for PDU session is proposed. A PDU session defines the association between the UE and the data network that provides a PDU connectivity service. Each PDU session is identified by a PDU session ID, and may include multiple QoS flows and QoS rules. There can be more than one QoS rule associated with the same QoS flow. A default QoS rule is required to be sent to the UE for every PDU session establishment and it is associated with a QoS flow. Within a PDU session, there should be one and only one default QoS rule. In one novel aspect, UE behavior and error handling for proper QoS rule management is defined for PDU session establishment and modification procedures to enforce the one and only one default QoS rule policy.
