Abstract: A method and a system for Internet Protocol (IP) session keepalive monitoring, a home gateway and a network device are provided. The method includes: receiving, by a User Equipment (UE) or an IP edge node, a Bidirectional Forwarding Detection (BFD) message sent by a Home Gateway (HGW), in which a first discriminator field value included in the BFD message is a difference between an IP address prefix of the UE and an IP address prefix of the HGW; and monitoring, by the UE or the IP edge node, whether an IP session between the IP edge node and the UE is keepalive according to the first discriminator field value in the BFD message. “Multihop BFD” is used as a keepalive monitoring mechanism of a “Multihop IPv6 Session”, thereby realizing keepalive monitoring of the “Multiple hop IPv6 Session”.

Abstract: A method for fracturing a subterranean formation penetrated by a well bore comprises formulating a fracturing fluid useful in hydrocarbon drilling having the properties of both a dispersing fracture solution and an aggregating fracture solution. In particular, the dispersing properties of the stabilizing fracture solution are able to act as a dispersing fracture fluid in the clay and earthen materials discharged from the pay zone in the flow-back fluids during hydraulic fracturing. At the same time, aggregating properties of the stabilizing solution stabilize the pay zone. This stabilization property allows the flow of hydrocarbon through the fractures for a significantly longer time than with prior art fluids.

Abstract: A system and method are described whereby a mobile device controls access to mobile applications based on access conditions associated with a current access network. To prevent mobile applications from running when the access conditions are not suitable, the mobile device includes a policy database used to store a list of access conditions that are inappropriate for launching the installed applications. The access conditions are based on the type of the current access network used by the mobile device for launching or maintaining the requested application session. The access conditions indicate whether the mobile device is currently accessing its home network or roaming on another provider's network. Similarly, the access conditions indicate the type of network access interface used by the current network to provide the data connection necessary to run the requested application. The policy database correlates predetermined actions with the access conditions associated with a given application session.

Abstract: A resource release control method, a communication system, and a device are configured to delete a bearer context on an original-side heterogeneous-system management network element (NE) even if a target-side management NE does not support interaction with a serving gateway (S-GW) and does not support an idle mode signaling reduction (ISR) mechanism. The resource release control method includes: acquiring version information of a target-side management NE, when a user equipment (UE) activating an ISR mechanism is handed over from an original-side network to a target-side network; and deleting a bearer of an original-side heterogeneous-system management NE, if the version information indicates that the target-side management NE does not interact with an S-GW and does not support the ISR mechanism. Meanwhile, a communication system and a relevant device are also provided.

Abstract: A retarding system for an electric drive machine (100) includes a direct current (DC) link (312), at which a DC voltage is developed, disposed between a rectifier (206) and an inverter (208). A first contactor switch (216) electrically communicates with a first rail of the DC link (312), and a second contactor switch (216) electrically communicates with a second rail of the DC link (312). A first resistor grid (214) is connected in series between the first contactor switch (216) and the second contactor switch (216). The first resistor grid (214) dissipates electrical energy in the form of heat by conducting a current between the first rail and the second rail of the DC link (312) when the first contactor switch (216) and the second contactor switch (216) are closed.

Abstract: A method and a coordinator of superframe management are disclosed. The method includes receiving, by a coordinator, a GTS request from a node; determining the type of the node; allocating GTS in an active period based on GTS characteristics carried in the GTS request when the node is determined as an energy restricted device; allocating GTS in an active period and an inactive period based on GTS characteristics carried in the GTS request when the node is determined as an energy unrestricted device. As can be seen from the method of the present invention, for an energy unrestricted device, allocated GTS may extend to an inactive period. Since the length of slots allocated to the energy unrestricted node is extended, the QoS of the energy unrestricted node is improved and guaranteed. Meanwhile, since the method of the present invention considers and makes full use of the inactive period in the superframe, the network throughput is improved significantly.

Abstract: In a regulating system and method of regulating the chassis of a motor vehicle, sensor data which are present for regulating the suspension and the damping of a vehicle body vehicle and describe the suspension state are forwarded to the regulating module of an antilock brake system. A state of the motor vehicle with regard to a brow situation can be determined from the sensor data. The sensor data or the state with regard to the brow situation are/is taken into consideration in the regulating module of the antilock brake system when determining control signals for regulating the brake pressure in brake apparatuses which are assigned to the wheels, in particular in the brake cylinders. This increases the driving safety considerably when driving over a brow and immediately after driving over a brow and increases the efficiency and reliability of the antilock brake system substantially in corresponding driving situations.
