Abstract

PROBLEM TO BE SOLVED: To correct deviation in receiving timing of a PCH(paging channel) and to be always in a correct waiting state. SOLUTION: Every time a PCH is intermittently received in a waiting state, a receiving number n is counted up (ST5). When a received PCH has incoming information and informative receiving instructions, they are severally processed (ST3, ST4, ST10 and ST11). When a receiving number n becomes a value N set preliminarily, a control channel is received at a timing when a BCCH (broadcast control channel) is estimated to come the next time with the timing of intermittent reception of the PCH as reference (ST6 and 7). In such a case, if a received control channel is a BCCH, an intermittent reception of the PCH is returned, without correcting receiving timing of the PCH (ST8). If a BCCH can not be received, continuous reception of control channel is performed to receive a BCCH and intermittent reception of a PCH is changed to after correcting receiving timing of a PCH to receive a PCH which corresponds to its own incoming group number (ST8 and 9).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable terminal device such as a portable telephone. Specifically, each time the PCH (Paging Channel) is intermittently received one or more times in the standby state, it is determined whether or not the BCCH (Broadcast Control Channel) can be received based on the PCH reception timing. The present invention relates to a portable terminal device in which, when reception is not possible, the PCH reception timing corresponding to its own paging group number is corrected to always be in a proper standby state.

[0002]

2. Description of the Related Art Simplified mobile phones (PHS: Personal H)
andyphone System) receives a control channel transmitted from a base station, calculates the PCH's paging group number to be received based on information included in the BCCH in the control channel, and, in a standby state, uses the PCH's own paging group number. The PCH corresponding to the number is intermittently received to obtain data such as an incoming call.

[0003] For example, as shown in FIG. 10, PCH corresponding to own paging groups number is assumed to be PCH _3. First, the control channel is continuously received to receive the BCCH.

[0004] Then, from the information in the BCCH to calculate its own incoming group number, based on the reception signal group number calculated by the reception signal group number calculation means for receiving the calculated PCH ₃ reception timing. Thereafter, only PCH ₃ is intermittently received at a fixed reception timing.

[0005]

As described above, in the portable cellular phone, in the standby state, the PCH intermittently receives the PCH corresponding to the destination group number among the control channels transmitted from the base station. I do.

However, PCH received intermittently includes:
Since the information of the called group number is not included, it is not known whether or not the correct PCH is actually intermittently received. If a PCH that does not correspond to its own paging group number is received, data such as an incoming call to itself cannot be received forever.

FIG. 11A shows intermittent reception in a normal state, in which PCH ₃ corresponding to its own called group number is intermittently received. In contrast, control channel discontinuous reception because of what Figure 11B or the like shows a case where shifted to PCH _4. In this case, intermittent reception of PCH ₄ which is a PCH that does not correspond to its own paging group number is continued, and PCH ₃ which is a correct control channel is not received. For this reason, data such as an incoming call to itself cannot be received forever.

Therefore, the present invention provides a portable terminal device that can always correct the standby state.

[0009]

In a standby state, a control channel transmitted from a base station includes control information data and a plurality of paging groups in which data indicating presence / absence of a call to each terminal is divided. A portable terminal device that intermittently receives a call group corresponding to its own call group number calculated from the content included in the control information data and its own terminal number, based on its own call group number. Receiving control means for controlling to receive control information data at a first timing estimated to be received at the first timing, and determining whether or not the control channel received at the first timing is control information data When the receiving channel determining means and the receiving channel determining means determine that the control channel received at the first timing is not control information data, the receiving group corresponding to its own receiving group number is received. In which and a reception timing correction means for correcting the reception timing of the paging groups to.

[0010] In the standby state, among the control channels transmitted from the base station, an incoming call group corresponding to its own incoming call group number is intermittently received. Each time a predetermined number of incoming call groups corresponding to the intermittently received incoming call group number are received, control is performed based on the reception timing of the incoming call group at a timing at which control information data is expected to come next. When a channel is received and the reception timing determination means determines that the received data is control information data, it is determined that intermittent reception of a paging group corresponding to the paging group number of the paging apparatus is normally performed, and the control of the paging apparatus is performed again. Intermittent reception of the incoming call group corresponding to the incoming call group number is performed. When the receiving timing determining means determines that the received data is not the control information data, the control channel is continuously received until the next control information data is received, and the control information data is received. Based on the control information data, the reception timing correction means corrects the timing of intermittently receiving the incoming call group corresponding to the own incoming call group number, and controls to shift to the standby state.

In this case, since the PCH defines only a single message, there is no area indicating the message type. 5 to 7 bits of octet 1, no call, BCD 13 digit or less PS number call service, hexadecimal 7 digit PS
A call service type such as a call service by number is displayed. The PS number is indicated by octets 1 to 7. Further, octet 8 instructs reception of a broadcast channel (BCCH). If a change occurs during intermittent reception, which will be described later, the PS receives the BCCH according to the reception instruction.

It is to be noted that the PS has a plurality of PSs depending on the paging group number.
PCH (PCH₁~ PCH_n) From PCH to be received
Understand. PS is the content of BCCH from PS number and CS
(N _PCH, N_GROUP, Control carrier configuration)
The incoming call group number is calculated by equation (1). here,
n_PCHIs the same number of incoming call groups, n_GROUPIs the incoming clustering factor

X = 2 if the groups are interrelated, otherwise
X = 1.

Incoming call group number = (PS number) MOD (n _PCH × n _GROUP × X) +1 (1) As described above, after the location registration is completed, the mobile station returns to the control channel receiving state and waits. State. In this standby state, the telephone (PS) 10 shifts to intermittent reception in which it receives only the PCH corresponding to the calculated incoming call group number (its own incoming call group number). In this case, since the PCH corresponding to the calculated paging group number exists for each LCCH superframe, intermittent reception is performed every 1.2 seconds.

As described above, in the standby state, the PCH corresponding to the own receiving group number is intermittently received to obtain data such as the incoming call. If a transition is made to a state in which the PCH is received intermittently, data such as an incoming call to itself cannot be received forever.

Therefore, in the present embodiment, in the standby state, every time PCH is received a predetermined number of times,
Based on the reception timing of the CH, the control channel is received at the first timing when it is estimated that the next BCCH will come, and it is determined whether or not this control channel is the BCCH. If it is not the BCCH, the control channel is continuously received to receive the BCCH, and the timing of intermittent reception of the PCH is corrected. That is, in the standby state, the microcomputer 11
Control operation according to the flowchart of FIG.

First, in the standby state, step S
At T1, the number n of PCH receptions is set to 0, and the PCH is received at step ST2. In step ST3, it is determined whether or not the received PCH includes incoming call information (own telephone number). If the PCH includes incoming information (own telephone number), incoming processing is performed in step ST10. If the PCH does not include the incoming information (own telephone number), it is determined in step ST4 whether the PCH includes a notification reception instruction.
If there is a broadcast reception instruction, the intermittent reception of the PCH is temporarily suspended, and the BCCH is received in step ST11. If there is no notification reception instruction in step ST4, after n is incremented in step ST5,
Proceed to 6.

In step ST6, it is determined whether or not n <N. Here, the value of N (natural number) is set in advance, and is set to, for example, 10. Then, when n <N, the process returns to step ST2, and the operations from step ST2 to step ST6 are repeated. If it is determined in step ST6 that n <N, the control channel is received at a timing at which it is estimated that the next BCCH will come based on the reception timing of the intermittently received PCH in step ST7. Then, in step ST8, the received control channel is BC
It is determined whether or not the channel is a CH. If the BCCH cannot be received, in step ST9, the control channel is continuously received to receive the BCCH, and to receive the PCH corresponding to its own destination group number. The PCH reception timing is corrected, and the process returns to step ST1 to shift to PCH intermittent reception again.

As described above, in the operation according to the flowchart of FIG. 8, every time the PCH is intermittently received N times, the PCH is received.
, The control channel is received at the first timing when it is estimated that the BCCH will come next, and it is determined whether or not correct intermittent reception is being performed. When the corresponding PCH is not received, the microcomputer 11 performs continuous reception of the control channel, receives the BCCH, corrects the PCH reception timing, and controls to return to the standby state. It can be in a state.

Here, the operation of correcting the reception timing will be specifically described with reference to FIG. PCH corresponding to own paging groups number is assumed to be PCH _3. First, a case where the PCH corresponding to its own paging group number is intermittently received as shown in FIG. 9A will be described.

When the PCH is received N times, the control channel is received at the timing when it is estimated that the BCCH will come next based on the reception timing of the PCH. At this time, since the discontinuous reception is normally performed, the BCCH is received, and the operation shifts to the discontinuous reception of the PCH again. Next, FIG. 9B
Does not correspond to its own incoming call group number, for example, P
The case where CH ₄ is intermittently received will be described. Also in this case, when the PCH is received N times, the control channel is received at the timing at which it is estimated that the BCCH will come next based on the reception timing of the PCH. However, when PCCH ₄ which is an erroneous channel is intermittently received, even if the control channel is received at the timing when it is estimated that the next BCCH will arrive, the BCCH which is intermittently received is shifted, so Cannot receive. Therefore, to receive the BCCH by performing continuous reception of a control channel, based on the reception timing of the BCCH, and corrects the reception timing of PCH to receive PCH ₃ is a PCH corresponding to own reception signal group number , And transition to a state of intermittently receiving PCH.

In the telephone 10 shown in FIG. 1, the telephone number of the other party is input by operating the key input unit 24 (numeric keypad 48 or the like), or after the redial data or the telephone directory data is searched, the telephone key 42 is pressed. Upon operation, first, the microcomputer 11 supplies telephone number data and the like as control data to the TDMA processing unit 15 and transmits the data to the base station through a control channel. As a result, the line connection with the other party is established, and a call is made possible.

Here, the communication is performed using the communication channel. At the time of the line connection processing, the communication frequency and the slot position data of the communication channel are transmitted as control data from the base station using the control channel, and the TDMA processing is performed. The data is supplied from the unit 15 to the microcomputer 11. The microcomputer 11
The radio section 13 is controlled based on the communication frequency data so that the transmission / reception frequency matches the communication frequency of the communication channel, and the slot selected by the TDMA processing section 15 is set based on the slot position data. Therefore, the call is made using the call channel notified from the base station.

Further, calling data is transmitted as control data from the base station using the control channel, and this calling data is supplied from the TDMA processing unit 15 to the microcomputer 11 and when an incoming call is detected, the calling sound is generated by the microcomputer 11. The output unit 23 is controlled to output a ringing tone, or the microcomputer 11 controls the vibration generating unit 22 to vibrate the telephone body 40.

While this calling operation is being performed,
When the call key 42 is operated and there is a response, the microcomputer 11
Response data is more control data than the TDMA processing unit 15.
And transmitted on the control channel to the base station. As a result, the line connection with the other party is established, and a call is made possible. Also in this case, the communication is performed using the communication channel notified from the base station.

In the talking state, the compressed voice data transmitted through the talking channel is output from the TDMA processing unit 15. The compressed audio data is supplied to the audio codec 16 and subjected to an encoding process, and then converted into an analog signal. Then, the received audio signal output from the audio codec section 16 is supplied to the speaker 17 and the speaker 1
7 outputs a sound.

The transmission audio signal output from the microphone 18 is supplied to the audio codec 16 and converted into a digital signal, and then subjected to a compression encoding process to form compressed audio data. Then, the audio codec section 16
The output compressed audio data is supplied to the TDMA processing unit 15 and transmitted to the other party through a communication channel.

In this case, "↓" of the cursor movement key 45
By operating the keys, ten keys 48 and special input keys 4
Character data can be transmitted by using the characters 9 and 50. In this case, the DTMF signal corresponding to the operated key is DT
The audio codec 16 output from the MF modem 19
Is supplied as a transmission audio signal.

As described above, the calling data is TDM
When an incoming call is supplied from the A processing unit 15 to the microcomputer 11 and an incoming call is detected, when the answering machine mode is set, a ringing tone is output only for a predetermined time, and the telephone is automatically answered to be in a call ready state. . Then, after a response message to the effect that the received voice signal is recorded is transmitted to the calling side, the recording of the received voice signal is started by the voice recording / reproducing unit 21.

When character message data by a DTMF signal is sent from the other party during an answering machine or during a call, the key data output from the DTMF modulation / demodulation unit 19 is stored in a conversion format under the control of the microcomputer 11. The character data is converted into character data with reference to the unit 20, and the character data is written in the character message area of the nonvolatile memory 25. When the character data is written in the non-volatile memory 25 as described above, the character message based on the character data is displayed on the liquid crystal display 26 and confirmed by long-pressing the “↑” key of the cursor movement key 45. It becomes possible.

In the above embodiment, the present invention is applied to a simple type portable telephone. However, the present invention is applicable to a control group transmitted from a base station in a standby state and corresponding to its own destination group number. Of course, the present invention can be similarly applied to other portable terminal devices that receive PCH intermittently.

[0054]

According to the present invention, every time the PCH is received a predetermined number of times, the control channel is received at the first timing at which the next BCCH is estimated based on the PCH reception timing. , When the BCCH cannot be received, the PCH reception timing is corrected so as to receive the PCH corresponding to its own paging group number, and the PCH shifts to the intermittent reception state.
, The reception timing can be corrected, and the correct standby state can be always maintained.
