Granted: 2012-03-27
Abstract: A data session with a wireless device (114, 116) ordinarily cannot be initiated from the network side because the wireless device has no predetermined IP or other network address. Methods are disclosed for instead causing the wireless unit to initiate a data session with a target destination or polling application (130, 150, 208), thereby obviating the IP addressing problem. A voice call is first initiated by a requester or polling application (100) to a remote wireless unit (112). The requester transmits a request message to the remote wireless unit via the wireless voice channel (108) using in-band techniques; preferably including a payload in the polling message that identifies the target destination. In response, the remote wireless unit initiates a packet data session (120, 140) with the target destination (130, 150).

La zone d'identité de séquences comprend généralement au moins 20 nucléotides non palindromiques (nt), par exemple, au moins 40 nucléotides non palindromiques. Dans quelques modes de réalisation, un PEG de 5 % est présent pendant la totalité des étapes de la réaction et/ou la réaction de réparation est exécutée par une polymérase de Taq ADN et une ligase compatible telle qu'une ligase Taq ADN. Cette méthode permet de réunir plusieurs fragments d'ADN dans un ordre et selon une orientation prédéterminés sans utiliser d'enzyme de restriction.
