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 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.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for detecting a specific event in a wireless communication system. SOLUTION: This invention discloses a method and apparatus for detecting a specified event in a wireless communication system. The invention includes an application program interface (API) that facilitates communications between a mobile station communication protocol stack, which communicates with a communication network, and a mobile station application. The mobile station communication protocol stack polls a memory when the mobile station application registers a specified event. Based on the polling, the mobile station communication protocol stack then detects the specified event. In another implementation, the mobile station communication protocol stack detects the specified event by an interrupt notice, which is triggered when the specified event occurs.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for channel optimization during point-to-point protocol (PPP) session requests. SOLUTION: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant, i.e., whether the mobile station is engaged in a call. COPYRIGHT: (C)2011,JPO&INPIT

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 a system for determining a time to answer an incoming packatized data call. SOLUTION: A communication device MT2 answers (530) an incoming packatized data call from a base station in response to the detection of a control signal or control information indicating the ready-state of the terminal device. A terminal device ready-state indicator may include control signals such as a high-state data transmit ready signal or the low-state to high-state transition of the data transmit ready signal after a ring-indicator signal has been activated to alert a subscriber of the incoming call, the ready-state indicator may also include control information such as a point-to-point protocol packatized data indicator flag embedded in a data stream generated from the terminal device, or the other information indicating that a point-to-point protocol packet has been sent by the terminal device.

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.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for early determination of network support for mobile IP in a wireless communication system. SOLUTION: A mobile node is in communication with a wireless network. Then a test is performed for a disconnect condition. The disconnect condition is an early indication of network support for the mobile IP as identified by at least a requirement for authentication. Early indication relates to identification of the non-support for the mobile IP prior to or during network packet connection. If the disconnect condition is found, the mobile node disconnects from the wireless network. If the disconnect condition is not found, the mobile node is left connected to the wireless network.
