Abstract: A method and apparatus that enables a mobile device to seamlessly transition between packet-switched wireless networks to while maintaining access to a resource is described. The invention includes a delay measurement component, a buffer management component and a mobile device component. The delay measurement component actively measures downlink packet delays from a packet duplication point to each of the interfaces of the mobile device with a single time reference. A buffer management component compares the measured delays to identify a delay difference and uses the delay difference to manage packet delivery on each network during the transition. A mobile device component includes functionality for assisting in the delay measurement and organizing packets received during transition. As a result of the above mechanisms, delay measurement and buffer management, “slips” and “repeats” due to network transition are minimized, which guarantees an enhanced Quality of Experience (QoE).

Abstract: Systems and methodologies are described that facilitate enhancing acquisition and handoff in a wireless network deployment by leveraging primary pilots and secondary pilots. The deployment can support more than one frequency band for operation, yet a mobile device can receive signals on one frequency band at a given time. Thus, a base station can transmit primary pilot(s) over frequency band(s) associated with operating data channel(s) as well as secondary pilot(s) over frequency band(s) that lack data channel(s) for the base station. Moreover, the base station can convey information that indicates to a mobile device whether each pilot is primary or secondary. Further, the mobile device can employ knowledge of pilot type (e.g., primary or secondary) as well as signal strength to effectuate handoff decisions; thus, disruptions in communication can be mitigated.

Abstract: A wireless LAN can be used to support audio communication sessions between wireless communication devices and wired communication devices both configured to operate according to the Internet Protocol. Both the wired and wireless communication devices generate and transmit frames of voice information over the LAN to each other and in the process of generating these frames they place a timestamp in each frame that is used by a receiving communications device to determine when the frame should be played in relationship to all of the other frames of voice information it receives. At times these communication devices can place incorrect timestamp values in the frames of audio information which can affect the quality of the communication experience for a user. I propose to correct any incorrect timestamp values by first recognizing that a timestamp value is incorrect and then rounding the value to the nearest frame boundary.

Abstract: An exemplary method implements route optimization in an IP telecommunication network that supports wireless mobile stations (MSs). IP address information related to packet flow for MSs is identified and stored in records at a local mobility anchor point (LMAP).

A route optimization (RO) message is transmitted to the first and second point of attachment nodes, where the RO message includes an IP address of the other point of attachment node.

Abstract: Measurement opportunities are provided to a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a CDMA wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The bursty nature of packet data transmission generates periods of inactivity or low traffic during a call.

Moreover, if the network has knowledge of the fact the WTRU is operating using a switched beam antenna, the network can use this information when making decisions on channel allocations, thus providing frequent measurement opportunities to the WTRU in order to support the switched beam antenna operation.

Abstract: In a reverse link management method in a multicarrier wireless communication system, an access terminal AT sends a Reverse Link Management Message to an access network AN. The Reverse Link Management Message carries information of the reverse link that the AT dropped.

The AT establishes a reverse carrier link (reverse link) based on said Traffic Channel Assignment Message and transmits data on the new reverse carrier link. According to this method, the AT can actively report the number of its containing reverse links to AN and inform the AN of the reverse links it has dropped, without further modifying other messages and steps in terminal connection process.

Abstract: A first device in a first local area network (LAN) searches for a first Universal Plug and Play (UPnP) enabled router with a first public network address. If found, the first device obtains the first public network address of the first router and configures a first mapping table of the first router to associate several ports number to the first device. These actions may be repeated by a second device in a second LAN for a second UPnP enabled router with a second public network address and several ports number. The two devices then connect through a secondary communication channel (e.g., a telephone network) to exchange networking information. The two devices then use the networking information to establish a computer network connection over a public computer network that couples the first and the second LANs for point-to-point communication.

Abstract: A network architecture provides Ethernet services over a Fibre Channel (FC) storage area network infrastructure. The fabric provides transparent bridging services to Ethernet end stations connected at the edge of the FC fabric via multi-protocol switches that support Ethernet over Fibre Channel (EoFC) technology. An Ethernet frame is received from a first Ethernet edge network by an ingress Ethernet port of a first virtual bridge and is encapsulated in a FC frame shell to form an EoFC frame. The EoFC frame is then transmitted out an egress FC port of the first virtual bridge and routed through the FC fabric using an FC routing protocol. When the encapsulated frame reaches an ingress FC port of a second virtual bridge, the EoFC frame is de-encapsulated to yield the original Ethernet frame, which is transmitted out an egress Ethernet port of the second virtual bridge into a second Ethernet edge network.
