Description of Related Art
Along with mobile phone and PDA (Personal Digital Assistant) (PDA) comprehensively are one, the operation between these two kinds of devices seems important synchronously and regularly synchronously.PDA adopts various forms, is pocket computer basically.Nearest technological progress all improves its disposal ability, function and memory capacity, thereby is comparable to many laptop computers.The user more and more relies on these devices, to replenish or to replace many activities of its big personal computer reservation.
In addition, the increase of mobile phone and internet rely on the growth at full speed of degree to accelerate the comprehensive and interoperability of these devices.Because mobile phone and PDA bulk cargo are in a housing, these install the most important synchronously automatically of operability and fiducial time.That is to say that the user of mobile phone needs and can provide the standard time benchmark automatically according to its time zone benchmark, and can upgrade the operation of its PDA or make this operation synchronous according to the time zone benchmark.The key element that can reach this requirement is a mobile telephone system.
Mobile phone has become the requisite part of telecommunications industry.Up-to-date and the widest mobile communication of use is a Cellular Networks system 1, as shown in Figure 1.Cellular Networks is defined as a kind ofly will cover the mobile communication system that is distinguished into the continuous geographic region that is called boxwork 11,13,15.Each grid comprises a base station (BS) 5,7,9, is a specific geographic region service in this network.Comprise processor, Receiver And Transmitter (not shown) in the part of BS, and play similar repeater, receive calling, and the calling that will receive passes to other interior users of grid, maybe land line is passed in this calling from the user.The operation of the control BS 5,7,9 of mobile switching centre (MSC) 3 provides interface to public switched telephone network (PSTN) 4 to wireless cellular network.Therefore, each grid in the net can a large amount of individual consumers 15,17,19,21 of independent process, but are restricted a bit because of its call treatment capacity number of users.When the user moved to another cell from a cell, hithermost BS is just transferred in the processing of user telephone call, and was such such as user 19.
When being positioned at cell 11, whole callings that user 19 sends or receives are all handled by BS 5.As long as user 19 stays shown in the A of position in the geographical frontier of cell 11 like that, the processing of its call is just still carried out at base station BS 5.Yet along with user 19 moves and enter the border (position B) of cell 11, next hithermost BS is transferred in the processing of its call.In this example, when user 19 when the direction from B to C moves, hithermost BS is the BS 7 of new cell 13.These interborough switching between some different BS are divided total system capacity, thereby make Cellular Networks have the communication service processing capacity of raising.
The service supplier of Cellular Networks system is subjected to contribute to the spectrum number quantitative limitation of cellular network communication.Therefore, increasing of Cellular Networks number of users forces the cellular network communication industry except that increasing usable spectrum, also inquires into the difference of increase capacity and replaces means.Comprise code division multiple access (CDMA) technology in these replacement means.CDMA is digital RF (RF) the channelizing technology of telecommunications industry association/electronics industry association interim standard-95 (TIA/EIA IS-95) regulation, this standard was announced in July, 1993, exercise question is " travelling carriage and the base station compatibility standard of dual mode wideband spread spectrum Cellular Networks system ", is incorporated herein by list of references.Adopt the wireless communication system of this technology that signal of communication is distributed unique word, and all expanding these signals of communication on public (broadband) apread spectrum bandwidth.As long as the receiving equipment in the cdma system has correct sign indicating number, just can be from other signals that same frequency band sends, successfully detecting and select simultaneously its signal of communication.The utilization of CDMA forms the raising of system communication capacity, improves total call quality, reduces noise, and provides reliable transport sector for data communication service.Making the attainable pith of above-mentioned time synchronized in the cdma system is the cdma system time.
In the CDMA digital system, the transmission of whole BS is according to the public cdma system time, and is synchronous in time.The cdma system time with Greenwich mean time (GMT) the time be designated as benchmark.The timing of chien shih overall network signal and operation is synchronous during with cdma system.Though mobile phone is pressed the system time encoded signals when pre-treatment, should the time currently do not offer the user in any meaningful or available mode.
Therefore, need a kind of system that the cdma system time is provided, so that make operation and timing between PDA and the mobile phone synchronous.Can in the accuracy scope of GMT time standard, inform user's current time if utilize like this, the system and method for this time.In addition, this system or method can be the user provides and allows some of the option of its selection, for example fiducial time of different time zone fiducial time.So the user can be set to local zone time with its mobile phone according to the time zone of selecting from providing option.At mobile phone and PDA comprehensively is in the system of a unit, and available this identical system time for example upgrades that other relate to the data of time specially among file, appointment, calendar or the PDA.
Summary of the invention
The present invention also offers this time user's system, equipment and method by a kind of network system time of discerning mobile phone is provided, and addresses above-indicated needs.According to the invention provides a kind of equipment that comprises portable digital device.This portable unit is related with previous local zone time, and is adapted to be received in the time coding signal that whole Cellular Networks sends, and this signal is represented the network system time.When this device activates, receive above-mentioned signal.This equipment also comprises from the export agency of received signal guiding system time and system time is transformed into the converter of local time.At last, this equipment comprises the connecting gear that previous local zone time is updated to the more new mechanism of current local zone time and current local zone time is passed to the user.

Describe in detail
As mentioned above, Fig. 1 illustrates a kind of typical Cellular Networks example.
In this configuration, when user 19 at first activated its mobile phone, this telephone set sent a series of signal, was used for the request to Cellular Networks 1 broadcast reception or transmission calling.Also send the sign of mobile phone and caller's position.This signal is by receiving near being enough to receive each BS of this signal according to signal strength signal intensity.Meanwhile, base station 5,7,9 sends the beacon signals that are called pilot signal continuously, be used to notify this system of potential user can with and ready.In case BS 5,7,9 receives the signal that the user sends, and the information that comprises in the validation signal, just make mobile phone can receive and handle pilot signal from nearest BS.Mobile phone is measured the signal strength signal intensity of incoming call, and the BS that generally will send peak signal is judged to be hithermost BS.
Fig. 2 illustrates that the pilot signal of BS sends.Particularly, from whole BS pilot signal transmitteds 29 of cdma cellular net system, and except that signal phase, all identical between each pilot signal.The a part of information that comprises in the pilot signal 29 is cdma system time 29a.What propose as mentioned is such, and the cdma system time, 29a was based on the GMT time standard.Present Cellular Networks system is used for system operation, charging etc. with this system time.The application of cdma system time is transparent to the user such as exemplary device such as devices 23.
Fig. 3 and Fig. 4 illustrate typical mobile phone 23 and PDA 25 respectively.The user of PDA device does not insert the external time source.PDA 25 has internal clocking, and this clock is set by the user, and does not change, unless user's modification.PDA 25 can comprise some information, such as the calendar and the timetable that depend on time and necessary user's artificial regeneration.Recently device, device 27 as shown in Figure 5 comprehensively becomes a unit with mobile phone 23 with PDA25, and its example has the pdQ series of Qualcomm.The integration unit 27 of Fig. 5 comprises PDA part 27a and the 27b of mobile phone portion.This integration unit 27 makes the user do well out of to show based on the automatic real-time time of the big markers scope of cdma system or other similar systems, to promote seamless function between mobile phone 23 and the PDA device 25.Fig. 5 also illustrates some example mode of operation of integration unit 27.The block diagram of Fig. 5 B explanation integration unit 27.
Fig. 6 A explanation is according to the example embodiment of the present invention of the automatic operation mode 28c realization of integration unit 27 shown in Figure 5.Shown in frame B40a, the user of integration unit 27 must at first activate this device.During activation, by the processor (not shown) reception pilot signal 29 (shown in frame B40a) of mobile phone.
After receiving pilot signal and activating integration unit 27, with the export agency 27c guiding system time, shown in frame B40b.Owing in pilot signal,, can and make its other information component separate the guiding system time by extracting time information with signal to the additional information coding.
Guiding system is after the time, and shown in frame B40c, converter 27d is transformed into the local time with system time.Local zone time comprises the system time of the correct local zone time (being user's local time zone 40c) that is transformed into the user.According to GMT fiducial time and utilize the time zone deviation to finish this conversion.For example, according to this user, cdma system time 29a backward 6 hours than GMT sees the example 31 of Fig. 8 for the Illinois.Of this sort, Australian user then shifts to an earlier date 11 hours than GMT.Therefore, for system transmits correct local zone time, cdma system time 29a is transformed to local time zone with above-mentioned these deviations.
System time is passed to the user through connecting gear 27i with local zone time after being transformed into the local time in frame B40e.The transmission of local zone time comprises that the standing part that for example user interface shows in integration unit 27 shows local zone time.After transmitting local zone time, in frame B40i, stop the automatic operation mode 28c of integration unit 27.
Fig. 6 B illustrates the database manipulation pattern 28e of integration unit 27 shown in Figure 5.This pattern makes the user have the ability of the PDA part 27a institute deposit data of management comprehensive device 27.Because the user has the information 25b that depends on the time of the PDA part 27a that deposits in integration unit 27, such as appointment and/or calendar (being shown in Fig. 7), this characteristic is more important.
Shown in Fig. 6 B, frame B42a, B42b and B42c are similar to frame B40a, B40b and the B40c of explanation automatic operation mode among Fig. 6 A.Like this, after system time was transformed into the local time, comparator 27e compared previous system time and the previous time of storing among the memory block B42h, shown in frame B42d.Be different from the current time if the comparative result of frame B42d indicates previous time, then with new mechanism 27f more this previous time be updated to the current time at frame B42e.Because the user may move to its last and make a phone call to locate different time zones, need carry out this comparison.The user can be like this at the PDA of integration unit part 27a sensitive data input time, and then these data are incorrect in new time zone.Thus, whether the previous time of relatively judging in frame B42d is different from current local zone time.
If previous time is identical with current local zone time, stop the database operator scheme at frame B42i.If previous time is different with current local zone time, then alert mechanism 27g reminds the user at frame B42f.User one obtains reminding, and the just optional 27h of related organization that activates makes the information that depends on the time of memory block B42h related with the current time or be updated to the current time, shown in frame B42g.The combination that can produce some different modes from the database update characteristic is such as new data and do not notify the user or abandon selecting this characteristic fully more automatically, shown in Figure 28 f.When abandoning selecting, not update time sensitive data.Among another embodiment, the available mode that is similar to the frame B40e of automatic operation mode transmits local zone time.
The manual operation mode of Fig. 6 C explanation integration unit 27.This manual operation mode allows the user to use subscriber selector 27k to select any desired time, and makes the system time transmission of this time as integration unit 27.For example, the user can be the setting that shifted to an earlier date 5 minutes or did any other expectation than system time with the time set of integration unit 27.In this pattern, without cdma system time 29a.
When activating manual mode, the user is at frame B44a active device, and for example selects by choosing the manual operation mode 28d shown in Fig. 5, thus selected manual operation mode, shown in frame B44b.This selection makes and represents the 27j of mechanism and can represent time zone pick list 31 to the user, and the user can only select a time zone from this table in frame B44c.Among the frame B44d, according to the expectation time zone of selecting, input mechanism makes the user can import the time of expectation.At last, among the frame B44e, after the time transmission user of connecting gear 27i with expectation, in frame B44f end process.
From the present invention of such explanation as seen, obviously available many modes change the present invention.These change and not to depart from the spirit and scope of the invention, and all these change those skilled in the art to be significantly, to be included in the scope of following claims.
