Abstract:
PROBLEM TO BE SOLVED: To provide a technology for supporting QoS related to a communication network utilizing different network technologies by a generic quality-of-service (QoS) model which is not dependent on network technology. SOLUTION: The generic QoS model may include a superset including all QoS parameters for all network technologies being interfaced and supported by a QoS module 330, e.g., 3GPP and 3GPP2. An application at a device may specify QoS for a traffic flow based on the generic QoS parameters in the superset. The generic QoS parameters may be converted to QoS parameters that are specific to a communication network. The converted QoS parameters are exchanged with the communication network and are used while exchanging traffic with the communication network. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a snooper to efficiently process at least one packet which arrives at a mobile station.SOLUTION: A large number of IP packets transmitted from an IP network by a wireless network to a mobile station connected to an electronic device such as a laptop computer are allotted to an application under execution on the electronic device. In order to differentiate the packet only allotted to the mobile station application, arriving IP packets are snooped and filtered, thereby significantly improving processing efficiency in the mobile station. In particular, a CID field of TCP/IP packets using a Van Jacobson compression technique is snooped and filtered.

PROBLEM TO BE SOLVED: To provide transmission of data with wireless communication systems, and more specifically, provide an apparatus and method for efficiently running applications on a wireless communication device.SOLUTION: A majority of the IP packets sent from an IP network over a wireless network to a mobile station which is tethered to an electronic device, such as a laptop computer, are destined for applications running on the electronic device. The embodiments are for snooping and filtering incoming IP packets to delineate only those packets destined for mobile station applications, which greatly improves the processing efficiency of the mobile station. In particular, the CID fields of TCP/IP packets utilizing Van Jacobson compression techniques are snooped and filtered.
Abstract:
PROBLEM TO BE SOLVED: To provide techniques to efficiently filter fragmented datagrams and route fragments. SOLUTION: For each fragmented datagram, a filtering node obtains filter parameters when fragments of the datagram are received, When all filter parameters are available, the node applies one or more filters on the filter parameters to obtain a filter result for the datagram and stores the filter result in an entry in a routing table. When the filter result becomes available, the node processes all fragments already received for the datagram in accordance with the filter result. As each remaining fragment for the datagram is received, the node immediately processes the fragment in accordance with the filter result. When the last fragment is received, the node clears the memory and the routing table entry for the datagram. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a handoff scheme in a communication system in which a roaming node seeks network access among different networks which are implemented by using different network interface layer protocols. SOLUTION: A node 56 may freely move from one network to the other with reduced levels of interruption with respect to network access. At the start of hand-off, the node receives an indication for the hand-off. The indication may be embodied in various forms such as a signal message indicating a change of the SID, NID or PZID. Alternatively, the indication can be in the form of information straight-forwardly included in a data packet sent to the roaming node prior to the hand-off. As the other alternative, the indication can be implemented as a distinguishable message pattern sent to the node. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile terminal and wireless device with common IP address. SOLUTION: A networked device shares a single IP address with a separate networked device. The networked device examines a port number of a received IP packet. The networked device routes the IP packet to an application on the networked device when the port number of the received IP packet corresponds to the application. Otherwise, the IP packet is routed to the separate networked device. COPYRIGHT: (C)2010,JPO&INPIT

The networked device examines a port number of a received IP packet. The networked device routes the IP packet to an application on the networked device when the port number of the received IP packet corresponds to the application. Otherwise, the IP packet is routed to the separate networked device. Alternately, instead of originating IP packets including as an origination address an IP address assigned to the separate networked device, the IP address may be "shifted" to between the networked device and a separate networked device by blocking transmitted IP packets originating in the separate networked device, and originating IP packets, which include as an origination address an IP address assigned to the separate networked device.

Abstract:
PROBLEM TO BE SOLVED: To attain a framing protocol efficient and firm in reducing an overhead and simplifying a payload. SOLUTION: In a system and a technology for establishing a communication link, a transmit source determines a frame boundary of a payload and a value of the transmit source is calculated as a function of subsets of the payload, the calculated value is attached to a payload within the frame boundary before the transmission of the frame. A value of a receive source is calculated as a function of subsets of the payload, the calculated value is compared with the received value, and a correct payload is detected as a comparison function.

Abstract:
PROBLEM TO BE SOLVED: To provide a mobile computing platform for assigning blocks of quality of service precedence values.SOLUTION: An ordered list of precedence values includes a number of blocks of precedence values. An operating system receives filters from an application. The operating system assigns a precedence value to each filter from the available block of precedence values that has the highest priority. Precedence values are assigned to maintain a precedence order specified by the application. Filters and their assigned precedence values are communicated to an entity that filters packets by applying the filters in the order of their precedence values. If an assignment is to be made when the lowest priority block is not available, then a repacking operation is performed to fill unused blocks in the list.
Abstract:
PROBLEM TO BE SOLVED: To provide techniques for supporting wireless data services and data connectivity on a TE2 device coupled to a wireless device using an Internet Protocol (IP)-based interface.SOLUTION: A wireless network assigns a single IP address to the wireless device, which assigns this IP address over to a TE2 device. The wireless device forwards packets exchanged between the TE2 device and the wireless network using the single IP address. The wireless device exchanges packets with the TE2 device by (1) using the private IP address for outbound packets sent to the TE2 device and (2) performing either address-based routing or packet filtering on inbound packets received from the TE2 device.
