20100014482 | RADIO BASE STATION AND RADIO COMMUNICTION SYSTEM FOR STARTING INTER-SYSTEM HANDOFF - It is possible to forcibly cause a terminal to perform an inter-system handoff for system control in a region where service areas of a plurality of radio access systems are overlapped.

20100014483 | Network Selection - A wireless user device, in radio communication with a first access point of one or more networks with which it could communicate via at least one of a plurality of access points, sends a network selection request to the first access point. If the network wishes to initiate a response from another access point in the same or another network, the first access point forwards the network selection request to one or more neighboring access points, in the same or another network. If any of the neighboring access points is able to communicate with the user device, that neighboring access point sends a response directly to the wireless user device and the wireless user device chooses the most suitable network from the responses sent. | 2010-01-21 |

20100014485 | BUFFERING PACKETS DESTINED FOR A MOBILE DEVICE WHILE THE MOBILE DEVICE MOVES FROM ONE NETWORK TO ANOTHER NETWORK TO PREVENT HANDOFF PACKET LOSS - A method and system for preventing packet loss during handoff of a mobile host between access networks. In accordance with an aspect of the invention, a home agent on a network maintains a FIFO (First In-First Out) buffer for every mobile host that it serves. When a packet destined for a particular mobile host is received at the home agent, it is assigned an incremental sequence number, encapsulated as an IP packet, and forwarded to the mobile host with the sequence number as an identifier. The packet and sequence number are thereafter stored in the buffer for a period of time after the packet was forwarded to the mobile host. After hand-off to the arriving network is completed, the mobile host sends the sequence number of the last-received IP packet to the home agent and the new care-of IP address. Using this sequence number, the home agent then determines whether any incoming packets had been routed to the previous care-of IP address. These are retrieved from the buffer, and resent to the new care-of IP address. | 2010-01-21 |
