摘要:
An access GW (201) receives, from a mobility management node (300), a transmission-path control signal for changing a route of only part of a data packet flow that pertains to a mobile terminal (400) and is originally relayed through the access GW (201) and a first mobility anchor (100A). In response to receiving the transmission-path control signal, the access GW (201) establishes a logical transmission path with a second mobility anchor (100B) for transferring the part of the data packet flow, and transfers the part of the packet flow to the second mobility anchor (100B) and also transfers a remaining part of the packet flow to the first mobility anchor (100A) by distinguishing a data packet received from the mobile terminal (400). As a result, for example, a mobility anchor can be switched for a part of data packets relating to the mobile terminal (400) under the initiative of the mobility management node (300).

摘要:
A method for facilitating communication in a mobile communication system in which address-delegating entities are involved, wherein mobile nodes attaching to the communication system get assigned an address or address prefix, wherein the address or address prefix assignment is delegated from an entity being associated with mobility management—mobility entity—to some other configuration component (2), is characterized in that the configuration component (2), upon being delegated by a mobility entity to assign a mobile node an address or address prefix, stores information about the delegating mobility entity. Furthermore, a corresponding mobile communication system with discovery functionality of address-delegating entities is disclosed.

摘要:
A method for supporting quality of service (QoS) mechanisms during a handover process or in preparation of a handover process, wherein a user equipment (UE) attaches to an access network (AN) via points of attachment (PoA), wherein the handover process supports changing connection of the UE from one of the points of attachment—current PoA—to another one of the points of attachment—target PoA—while maintaining all ongoing connections of the UE, wherein signalling messages are exchanged between the current PoA and a second PoA during or in preparation of the handover process, the second PoA including the target PoA or a candidate for the target PoA, and wherein the AN supports inner QoS mechanisms on a communication path within the AN, the communication path being used for communication between one of the PoA and a core network (CN) or between one of the PoA and a network entity within the AN, is characterized in that a triggering message is sent to the second PoA by the current PoA, the triggering message being received by an UE proxy located on the second PoA, wherein the UE proxy, in reaction to the triggering message, controls the inner QoS mechanisms to ensure QoS on the communication path.
摘要:
A method for detecting attacks to multimedia systems, wherein a communication path (1) is established within the multimedia system by a multimedia communication flow between a communication source and a communication destination, is characterized in that at least two devices (3, 4, 8) are provided along the communication path (1), each the device (3, 4, 8) acting as inspection device (2) that is enabled to inspect the multimedia communication flow that transits the inspection device (2), and that the results of the single inspections are accumulated along the communication path (1). Furthermore, a multimedia system with attack detection functionality is described.
摘要:
A reliable and flexible method for controlling traffic within a network structure without the addition of remarkable complexity to the core network is provided, the structure including a PDN (Packet Data Network), an operator core network with a DNS (Domain Name System) server, a HeNB (Home evolved Node B) or HNB (Home Node B) and/or eNB (Evolved Node B) or NB (Node B) and a UE (User Equipment) that is associated with the HeNB or HNB and/or eNB or NB. On the basis of a predefinable routing policy the DNS server is controlling whether a traffic from a UE to a destination address within a local network associated to the HeNB or HNB or eNB or NB or within a PDN and/or vice versa will be routed via the core network or directly via the local network in support of local network protocol access or selected network protocol traffic offload.
摘要:
An apparatus for measuring optical properties of an object—such as, in particular, an eye—comprises a wavefront sensor for surveying wavefront aberrations generated by the object and an optical coherence tomograph, so that both wavefront aberrations and structures of the object can be surveyed. For this purpose a broadband laser radiation-source is provided for the OCT. A reference beam is generated with a retroreflector, and a beam-splitter serves as optical component both for the wavefront determination and for the OCT.

Embodiments provide a method of forming a chip package. The method may include attaching at least one chip on a carrier, the chip including a plurality of chip pads on a surface of the chip opposite to the carrier; depositing a first adhesion layer on the carrier and on the chip pads of the chip, the first adhesion layer including tin or indium; depositing a second adhesion layer on the first adhesion layer, the second adhesion layer including a silane organic material; and depositing a lamination layer or an encapsulation layer on the second adhesion layer and the chip.
摘要:
In order to save energy in EPS network, some of the MMEs and/or S-GWs are allowed to sleep (power down), when network's traffic load is decreased. When the traffic load becomes heavier, the network can power up some of the formerly sleeping MMEs and/or S-GWs.
