Fast mobile originated call in slotted mode

A mobile station comprising:

• a user interface whereby a user input may be entered at a first time;
• circuitry for comparing a threshold time to the first time, wherein the threshold time is related to a slot time;
• and
• a processor for calculating a time-dependent code according to a first solution if the first time is earlier than the threshold time, and according to a second solution if the first time is later than the threshold time.

A method for operating a mobile station in a slotted mode, comprising:

• receiving a network connection request from a user at a first time;
• comparing the first time to a predetermined threshold time;
• and
• deciding whether to delay or to immediately initiate a start of network-connection procedures.

A method for determining how a mobile station operating within a slot of a slotted mode acquires a time-dependent code, comprising:

• determining a threshold time tthresh based on a slot cycle index;
• receiving an input at a user interface of the mobile station at a current time tcurr;
• comparing tcurr to tthresh;
• performing pilot acquisition of the time-dependent code if tcurr is earlier in a slot than tthresh.
