Private network request forwarding can include receiving a request from a user for Internet services over a public network. Private network request forwarding can include analyzing the request and determining whether the request is legitimate. Private network request forwarding can include forwarding the request to an entity through a private network when it is determined that the request is legitimate, wherein the user has access to the entity through a proxy.

Proxying Session Initiation Protocol (SIP) communications in a load balancing device. An outgoing SIP message is received from a session border controller device. The received outgoing SIP message comprises a routing control parameter in the form of a Uniform Resource Identifier (URI). The received outgoing message comprises one or more additional outgoing routing control parameters different to the URI. The one or more additional outgoing routing control parameters have been originated at the session border controller device to control one or more outgoing routing characteristics at the load balancing device. The one or more additional outgoing routing control parameters are extracted from the received outgoing SIP message. The outgoing SIP message is forwarded to a peer device using the one or more outgoing routing characteristics on the basis of the one or more extracted outgoing routing control parameters.

A method executed in a plurality of domains, each of the plurality of domains including a plurality of switch apparatuses, the method includes receiving, by a first switch apparatus included in a first domain of the plurality of domains, a packet from a second domain, adding, to the packet, a header region in which a hop number of the packet is to be registered, transmitting the packet with the header region from the first switch apparatus to a second switch apparatus of the plurality of switch apparatuses included in the first domain, increasing the hop number registered in the header region in response to the transmitting of the packet from the first switch apparatus to the second switch apparatus, and when the packet is transmitted from the first domain to a third domain of the plurality of domains, resetting the hop number registered in the header region.

Telecommunications network components configured to manage call control of a communication session of user equipment are described herein. An anchoring network device may proxy signaling traffic for the communication session. The anchoring network device may determine a routing identifier based at least in part on which access network, or which type of access network, is carrying the communication session, and may transmit state information of the communication session to a call-control server in association with the routing identifier. The call-control server may provide control information of the communication session to the anchoring network device in response to the state information. The anchoring network device may modify the communication session, e.g., by adding or dropping one or more parties, in response to the control information. The routing identifier may be determined based at least in part on capabilities of a communication session indicated in a session-initiation message.

A network switching system and method and a computer program product for operating a network switch are disclosed. The network switch includes a multitude of input ports and a multitude of output ports. In one embodiment, one processing device is assigned to each of the input ports and output ports to process data packets received at the input ports and transferred to the output ports. In one embodiment, the method comprises creating an intermediate adjustable configuration of processing devices functionally between the input ports and the output ports, and assigning the processing devices of the intermediate configuration to forward the data packets from the input ports to the output ports to obtain a balance between latency and synchronization of the transfer of the data packets from the input ports to the output ports. In an embodiment, software is used to create and to adjust dynamically the intermediate configuration.

In MIMO wireless communication networks, receiver MIMO antenna parameters are not static over time. For example, the MIMO channel correlation is higher for high frequency bands than for low frequency bands. This variability of the receiver antenna parameters introduces uncertainty based the reported CSI (e.g., CQI, PMI, RI) if the network uses only static assumptions for such antenna parameter values. In embodiments, the UE determines the current status of its receive antenna parameterssuch as number, configuration, correlation, and power imbalanceand transmits this information to the network (e.g., serving BS). The network node then based on the received information performs one or more radio operational tasks leading to more efficient use of radio resources and enhanced system performance.

A module unit for connecting a data bus participant to a local bus. The module unit has a first input interface and a first output interface which can be connected to the local bus, a first data connection interface which can be connected to the data bus participant, and a first switch which is adapted so as to assume a first or a second switch state depending on a control input from the data bus participant, connect the first input interface to the first output interface in the first switch state, and connect the first data connection interface to the first output interface in the second switch state.

In one aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided to reduce overhead at the expense of increasing latency for UEs with weak link gain, while latency for most UEs may remain the same. The apparatus may be a UE. The apparatus may transmit a RACH preamble to a base station in one or more attempts. The apparatus may receive, through a random access response message from the base station, information including the number of attempts the base station uses to decode the RACH preamble. The apparatus may adjust the transmission power for the connection request message according to the number of attempts the base station uses to decode the RACH preamble. The apparatus may transmit the connection request message using the adjusted transmission power.
