Patent number: 8126469Abstract: Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.Type: GrantFiled: November 30, 2006Date of Patent: February 28, 2012Assignee: QUALCOMM IncorporatedInventors: Ragulan Sinnarajah, Edward G. Tiedemann, Jr., Ramin Rezaiifar, Jun Wang, Duncan Ho

Patent number: 7688786Abstract: Techniques for avoiding data loss and reducing registration overhead in a wireless packet data communication system are disclosed. In one embodiment, a mobile station adds each connection to a connection list following registration with the PCF. The mobile station need not reregister a connection included in the connection list when it again enters the PCF's coverage area. In another embodiment, a PDSN maintains a connection table, with one or more connections for each mobile station. The PDSN transmits data to the mobile station along one of the connections. In yet another embodiment, a PDSN transmits on an active connection, if one exists. In yet another embodiment, connections in a connection list or connection table are removed when a corresponding inactivity timer expires. Various other embodiments are also presented.Type: GrantFiled: September 17, 2003Date of Patent: March 30, 2010Assignee: QUALCOMM IncorporatedInventors: Nischal Abrol, Duncan Ho
