A method for accelerating TCP/UDP packet switching. The method involves determining whether exception processing is necessary; if not, the packet is forwarded to a special stack for expedited processing. Packets requiring exception processing are forwarded to the conventional stack.

A method in a system function capable of differently handling unattended data traffic as compared to attended data traffic. By using a dedicated policy on how to handle unattended data traffic, detected unattended data traffic is handled according to the dedicated policy. A communication device, a radio network node and a network node capable of differently handling unattended data traffic as compared to attended data traffic are provided for enforcing a policy to comply with requirements in 3GPP TS 22.101 regarding handling of unattended traffic at user plane congestion. Further embodiments provide for enforcing policies even in an uncongested state.

Embodiments of a mobile device, a User Equipment (UE), and method for supporting emergency calls on a packet-switched network are generally described herein. In some embodiments, the UE may be configured to support emergency calls in accordance with a 3GPP protocol and with eCall in an IP Multimedia Subsystem (IMS) session. The UE may comprise hardware processing circuitry configured to transmit traffic packets to an Evolved Node-B (eNB) for forwarding to a receiving station, which may be a Public Safety Answer Point (PSAP). In some embodiments, the transmission of traffic packets during a packetization period may be restricted to one of transmission of voice packets or transmission of data packets. In some embodiments, at least some of the data packets may include Minimum Set of Emergency Related Data (MSD), and the IMS session may be configured in accordance with Real Time Transport Protocol (RTP).

In one embodiment, an apparatus for providing quantized congestion notification (QCN) proxy functionality to a network device control plane includes a processor and logic integrated with and/or executable by the processor, the logic being configured to enable QCN proxy functionality for a particular congestion notification priority value (CNPV) on each edge port of a QCN edge switch, wherein the QCN edge switch includes one or more edge ports connected to devices outside of a congestion notification domain (CND) that operates on the particular CNPV, and forward congestion notification packets received at the QCN edge switch using the QCN proxy functionality when the packets are destined for one of the devices connected outside of the CND that is not QCN-enabled. Other systems, methods, and computer program products for providing QCN proxy functionality to a network device control plane are described in more embodiments.

Technology for initiating emergency calls is disclosed. A minimum set of emergency related data (MSD) associated with the emergency call may be identified at a terminal equipment (TE) of a mobile terminal. An attention (AT) command may be generated that includes the MSD and selected configuration information related to the emergency call. The AT command may be sent from the TE of the mobile terminal to a mobile termination (MT) of the mobile terminal in order to setup the emergency call, wherein the mobile terminal (MT) routes the emergency call to a public safety answering point (PSAP) in a communication network.

Various methods, systems, and apparatuses can be used to control flow in an ethernet environment. In some implementations, methods can include receiving a flow of ethernet frames at a first device via an ethernet switch, determining that a buffer at the first device exceeds a threshold for an incoming flow, generating an initial pause frame operable to pause only a second device, and transmitting the initial pause frame to the ethernet switch.

A wireless apparatus includes a communication control unit, a transmission unit for transmitting a message packet, a reception unit for receiving the message packet, and a storage unit for storing a transfer table in which transfer destination information is linked with a transfer priority indicating its priority among wireless apparatuses for transferring the message packet to a transfer destination. The communication control unit refers to the transfer table based on information on a transmission source and a transmission destination included in the received message packet. When the wireless apparatus of the transfer destination or the transfer priority is not determined, the communication control unit performs a transfer operation using broadcast communication. When the wireless apparatus of the transfer destination and the transfer priority are determined, the communication control unit performs a transfer operation using unicast communication in which the wireless apparatus of the transfer destination is specified.

A control plane load in a mobile network is managed. The mobile network includes a radio access network having a base station adapted for connecting to a plurality of user equipments (UEs) over a radio interface, and a core network (CN). The RAN determines a RAN control plane load, and transmits an information indicative of the RAN control plane load over a mobility management server to a policy server of the CN to initiate a traffic management in the CN based on the RAN control plane load. Related base stations, mobility management servers, and policy servers are disclosed.

A data update method, a client, a server and a system for data update are provided. Identifiers and update priorities of data strings to be updated in an application data packet are acquired. The data strings to be updated are classified, according to a predetermined threshold, as data strings to be updated having priority higher than the predetermined threshold and data strings to be updated having priority lower than or equal to the predetermined threshold. Before the application data packet is started, update data of the data strings to be updated having priority higher than the predetermined threshold are acquired and updated. After the application data packet are started, the update data of the data strings to be updated having priority lower than or equal to the predetermined threshold are acquired and updated.

In one embodiment, a system includes a network having one or more devices interconnected therebetween, the network including a first device having a first port and logic integrated with and/or executable by a first processor, the logic being adapted to exchange credit exchange (CE) capabilities between the first port and a second port of a second device in the network, receive a credit grant packet from the second port, the credit grant packet indicating credits granted to the first port, and send one or more packets of data from the first port to the second port, the one or more packets corresponding with the granted credits. Other systems and methods for providing credit-based flow control are described according to more embodiments.
