摘要:
Apparatus for and methods of enabling a gateway node of a first packet-switched data network to select a first channel for transferring a data packet to a destination packet data protocol address of a correspondent node provided service in the first network are disclosed. The gateway node is configured to select the first channel from a plurality of channels configured to transfer data packets to the destination packet data protocol address of the correspondent node, wherein the data packet is sent from a mobile node of a second packet-switched data network external to the first network, and wherein the mobile node has been in a communication session with the correspondent node while provided service in a third packet-switched data network different to the second network.

Mitigation of battery consumption will occur by prioritizing those units utilized for relay purposes. The prioritization scheme favors actively transmitting units over inactive units. In yet another embodiment, those units using real-time services are prioritized over active units using non-real time services.

The invention relates to a method for the redundant transmission of messages in a distributed real-time system. The real-time system comprises two or more computing nodes (101-108) and one or more star couplers (201-209). The computing nodes (101-108) are connected to the star couplers (201-209) by means of bidirectional communication lines (301, 302, 303), and the star couplers (201-209) are connected to one another by means of bidirectional communication lines (310). The star couplers (201-209) connected by means of the communication lines (310) form a network infrastructure (200), wherein one or more star couplers (201-209) of the network infrastructure (200) carry out one or more activity rasters (1000). An activity raster (1000) consists of alternating active phases (502) and rest phases (501), and precisely one activity raster (1000) is assigned to each message transmitted in the network infrastructure. The invention further relates to an infrastructure and to a real-time system with such a network infrastructure.

An object is to provide a network system, a path control apparatus, a path control method, and a program that can realize flexible routing in a communication network. The network system according to the present invention is a network system including a base station (11), a gateway (12), and a path control apparatus (13) for controlling a communication path between the base station (11) and the gateway (12). The path control apparatus (13) is configured to perform path control on a path between the base station (11) and the gateway (12) using second identification information that is associated with first identification information for identifying a communication terminal (101) that communicates with the base station (11) and is uniquely identified inside a network system.
摘要:
A stationary short-range wireless communication device acts as a node of a network where nodes are isolated from each other and comprises a communication unit detecting at least one mobile wireless device in the vicinity of the node, a data memory provided for node data (ND) and a control unit controlling the transfer of data between the stationary short-range wireless communication device and the mobile wireless device, which transfer comprises the transfer of node data (ND). The mobile wireless device comprises a data memory for node data (ND) and a control unit (60) that receives the data from the node comprising node data (ND), stores the node data (ND) in the data memory, determines if the mobile wireless device is in the vicinity of another network node and if so transfers the node data to the other network node.
摘要:
A wireless network system includes a base station of a first network and a user equipment camping on the first network. The user equipment receives an indicator, a probability value within a predetermined range and at least one RAN rule from the base station. When the indicator is set to a specific value, the user equipment generates a random value within the predetermined range. When the at least one RAN rule is satisfied and a probability condition associated with the random value and the probability value is fulfilled, the user equipment steers traffic from the first network to a second network or from the second network to the first network.
摘要:
The present embodiment discloses a registration method, intercommunication method, handover method for a mobile node and a network element. The intercommunication method for a mobile node includes: after an enhanced mobile access gateway receives a data packet transmitted by the mobile node to a peer node for the first time, if the enhanced mobile access gateway provides an ePMIP service to the mobile node, the enhanced mobile access gateway judging whether a peer mobile access gateway to which the peer mobile node is currently attached provides an ePMIP service to the peer mobile node, and if so, forwarding the data packet in an ePMIP manner, and creating a local forwarding entry to instruct a subsequent packet to be forwarded in the ePMIP manner, and if not, forwarding the data packet in a PMIP manner, and creating a local forwarding entry to instruct a subsequent packet to be forwarded in the PMIP manner.
