摘要： The invention is directed to a process for transferring data packets through a protocol stack employed by the device for transmitting packets on a packet connection to a wireless network, said wireless network operating at least two, distinct wireless access technologies such as GSM/GPRS and UMTS. The packet transfer process generally comprises each layer of a protocol stack for a currently active packet connection path providing confirmation to a next, higher layer in the stack of successful reception of a data packet from that layer, thereby confirming successful transfer of the data packet through the stack. The first layer of the stack stores a copy of a transferred packet until such time as its receives confirmation from the next, lower layer of successful transfer of the packet of the stack. In the absence of such confirmation and on the occurrence of a switch (hand-off) of the packet connection to a new connection path, particularly one of a different wireless access technology, the stored packet is transferred to the protocol stack to be employed by the wireless device for the new packet connection path. Consequently, the packet transfer process avoids packets being lost on the occurrence of a switch between different technology wireless access packet connection paths.

摘要： A system and a method for multimedia multicast transmission in a mobile wireless network are proposed, which can be applied in a multiple-antenna system as well as a single antenna system. The basic message and additional message are transmitted at the same time. Receivers with different capability also with different complexities are used to demodulate different message. In order to design low-complexity receiver, the signal can be demodulated noncoherently for multimedia transmission.

摘要： Secure access by a mobile wireless terminal of a wireless telephony network is achieved by having a Home Location Register store the terminal's temporary and permanent identities. Upon accessing the network following initial registration, the terminal sends a temporary identity to a Serving GPRS Support Node (SGSN). If no serving node in the network knows the terminal, the terminal need not sent its permanent identity in clear as was previously required. Rather, the serving node need only query the HLR since the HLR can map the terminal's temporary identity to its permanent identity. In this way, the permanent identity of the mobile wireless terminal remains secure.
摘要翻译：无线电话网络的移动无线终端的安全接入是通过使归属位置寄存器存储终端的临时和永久身份来实现的。在初始注册之后访问网络时，终端向服务GPRS支持节点（SGSN）发送临时身份。如果网络中没有服务节点知道终端，则终端不需要像之前所要求的那样清楚地发送其永久身份。相反，服务节点仅需要查询HLR，因为HLR可以将终端的临时身份映射到其永久身份。以这种方式，移动无线终端的永久身份保持安全。

摘要： A method of Authentication Authorization and Accounting (AAA) in an interworking between first and second networks that do not belong in the same asministrative domain, using certificate based transactions. In the method according to the invention, the second network sends a public key to the first network, and a certificate to a mobile device. The certificate includes information regarding the subscription level of the mobile device and is signed with a private key of the second network. Upon detection of the first network the mobile device transmits the certificate and the first network authenticates the certificate using the public and private keys of the second network, and authorizes access to the network in response. The first network then sends a session key encrypted with a public key of the mobile device. The mobile device decrypts the session key with a private key and access the first network using the session key. In this manner, interworking is implemented without requiring the deployment of a special interworking function to bridge between the two different types of networks.

摘要： A method of obtaining by use of a laser measuring apparatus position measurement error information of a body to be moved under computer control in a volumetric space along paths having designated measuring points for position error evaluation or correction. The method in a preferred form includes the steps of directing a laser beam in a given direction in said space and placing a laser beam reflector on the body to be moved in directions non-parallel to said direction, the reflector being sufficiently large that it will receive and reflect said directed laser beam back to said apparatus for actual reflector distance measurement along the beam path as said body is so moved. Then, with the computer of said system moving said body along said non-parallel paths measuring and recording with said apparatus the actual positions of said reflector along said beam path as the body reaches said various measuring points. The actual reflector position measurements are compared with the ideal reflector measurements and from the reflector position error so determined the body position error components at said measuring points are computed.
