Description

FIELD OF THE INVENTION

The invention relates to a combination paging system (peydzhingsistema) and a radio telephone system and a method for paging a transmission of an acknowledge back signal.

BACKGROUND OF THE INVENTION

Selective call signaling systems, such as personal call systems or the so-called paging systems provide one-way radio frequency transmission of selective call messages, called paging messages, from the sender to the paging recipient. The sender of the message connects to the personal call system via the public dial-up telephone network system or other input interface means and transmits the information from the message to the personal call terminal. The information contained in the message is encoded in a standard transmission protocol modulated on a carrier signal and transmitted as a radio frequency signal to a personal call receiver. The personal call receiver receives the signal, demodulates it, and decodes it to recover the message and present it to the subscriber system that is a user of the receiver.

Since selectively transmitting a call is a one-way communication system, the sender of the message does not understand (no feedback) whether the subscriber receives a message. Transmission of a return acknowledgment signal has been developed to inform the system of the reception of the message by the receiver. In addition, in order to avoid interference between the paging and the confirmation acknowledgments, the system communication path or airtime must be reserved for the acknowledgment signals. Air time is expensive, so it is advisable that it does not engage with feedback confirmation signals.

Since transmission systems selective call signals are unidirectional systems, building communications path of return confirmation signal is associated with large investments. In addition, acknowledgment signals are rarely transmitted and require little airtime. Therefore communications path would be inefficient and can not provide the service provider a sufficient monetary return for the added quality - confirmation tone.

What is needed is a system with an acknowledge back signal which does not take air time from the selective call signaling and does not require communication path.

SUMMARY OF THE INVENTION

In one embodiment of the invention there is provided a selective call receiver comprising a radio frequency receiver for receiving personal call signals transmitted from a personal call terminal, a decoder connected to the radio receiver to decode the personal call signals to recover the paging message, flag paging message identifier requiring a acknowledge signal, and a controller to connect to the paging terminal via pa iotelefonna system and transmission signal back to confirm if the identifier determining that the page is marked with a flag.

In another embodiment is provided a method for transmitting messages in a paging system to a combination radio telephone and radio paging receiver. The method involves the operations of receiving the message from the sender of the message, determining whether the sender of the message requests a confirmation acknowledgment upon receiving the information from the message from a radio paging device, marking the message with a flag for determining it as a message, requesting a return acknowledgment of its acceptance if the sender desires such a signal and transmission of the flagged message to the combination radiotelephone and radio pager. The method further comprises the steps of coupling to the combination radio telephone and radio pager via a radio telephone system, receiving the requested acknowledge back signal via the radio telephone system, and advising the message originator that the message was received.

According to FIG. 1, a selective call signaling system combining a wide area of personal call systems 10 and a radio telephony system, such as a wireless telephone system 15, uses a public switched telephone network (OCTM) 20 to communicate with each other. In the preferred embodiment of the invention utilizes a second generation cordless telephone (CT-2), which is less expensive than other radio telephone systems such as cellular telephone systems. The sender of the message using the input device peydzhingsaobshtenie 25 to enter information about paging through the public switched telephone network (PSTN) 20 for encoding and transmission to the subscriber of the paging system 10.

The device for introducing peydzhingsaobshteniya 25 is a phone for the introduction of speech (audio) or digital information. Device The page entry 25 may also include a device for data processing, such as a computer terminal, for generation of paging information comprising graphics, facsimile or alphanumeric information.

The sender of the message determines (initiates) the transmission sequence of the message via the paging input device 25 by entering a voice or information message in the form of a call to the access number of the specific personal call device (eg, a call radio (radio pager) / radio telephone). 40). The sender connects to a personal call terminal 32 via the telephone network interface 30 of the personal call system 10 and the public switched telephone network route 20a to be processed from the personal call terminal 32. When the incoming call is answered, from the personal call terminal call 32 plays a pre-recorded message that provides access to the message sender to the system 10, describes how the originator can enter a paging message and action not desirable confirmation that the message was received. The sender responds by entering a speech or information message and a special coded signal to indicate that he or she wants confirmation of the successful reception of the message.

In the personal call terminal 32, the message is initially entered into the clipboard after the sender has completed the sequence entry, the personal call terminal 32 accesses the subscriber database 34 to receive the subscriber's address, which address is associated with the personal information call to create a paging message. According to the invention, if the sender has introduced a special encoded signal indicating the desired acknowledgment, the acknowledgment flag block 42 of the personal call terminal 32 means the flag message and the terminal 32 includes the flagged message in the message queue block 36 for their later transmission. Unit to indicate a message flag to acknowledge back 42 may for example indicate the message by using an address that is reserved for messages with acknowledge requests, or it can connect to an acknowledgment request flag to the functional unit for common message must be sent.

The paging messages stored in the message queue block 36 are sequentially retrieved via the personal call terminal 32 and fed to the personal call transmitters 38 for transmission as selective call signals.

Selective call signals transmitted from the paging system 10 are received by the combination radio paging receiver (pager) and radio telephone 40. The pager receives the selective call signals. The radiotelephone, for example a wireless telephone transceiver (CT-2), is connected to the public switched telephone network 20 via the radiotelephone system 15.

According to a preferred embodiment of the invention, the combined radio pager and wireless telephone transceiver 40 receive selective call signals transmitted by the personal call system 10 through the personal call transmitters 38. If a flag message is received from the combined radio pager and wireless telephone transceiver 40 a wireless telephone connection is created between them and the wireless telephone system 15.

A local call transceiver 50, comprising the receiving tract 50a and the transmission tract 50c, receives the acknowledgment signal from the radio pager / wireless telephone transceiver 40 together with the information determining the access numbers to the personal call system 10 via the public dial-up telephone network 20. The acknowledgment signal and the access information are fed to the controller of the call 52 using the access information to call the paging system 10 via telephone die Mrs to the telephone station interface 54 of the telephone call station 15. Once the call signal is introduced into the controller 52 and the personal call terminal 32 via the public switched telephone network 20b 20, the acknowledgment signal indicating "received message" is sent to paging terminal 32. The paging terminal 32 after reception of the acknowledgment signal can generate a signal response to a received message which is returned to the sender of the message in the input device of peyd 25. This sender response message may appear while the caller is waiting for the incoming telephone line of the telephone network interface 30, or may be directed to a pager or other connection device capable of receiving the reply message.

The acknowledgment signal can indicate the type of message that was received (ie voice, numeric or alphanumeric message), the time the message was received, whether the message was received without error or not, or whether the acknowledgment signal it is personified. The personal call terminal 32 may transmit the additional information received to the sender of the message. In addition, the acknowledgment signal could also be used from the terminal 32 to initiate retransmission of the message, which is received in error.

Therefore, according to the invention, the Paging System 10 does not need to use the airtime or the busy channel to receive confirmation signals from the radio pager. Pager / cordless telephone transceiver using a wireless telephone link to submit confirmation signal to the paging system 10 to provide information in real time to the message sender that the message was accepted.

According to FIG. 2, the flowchart for receiving a call from the paging terminal 32 (FIG. 1) starts from the paging system introduced by block 100. The processing process waits for the incoming call 102 to be received by the sender of the message . When incoming call is received

102 via the telephone network interface 30 (FIG. 1), the call is answered 104 (FIG. 2) and the personal call terminal 32 generates a sound prompt 106 inviting the message sender to enter the message through the paging input device 25 (FIG. 1). When the message is entered, it is stored in a buffer memory of the terminal 32 (Figure 1) until the end of message 110. When the end of message is detected 110 (Figure 2), it is determined whether it is desired to return acknowledgment signal 112. If no acknowledgment signal 112 is requested, the message is called from the temporary message memory 42 through the personal call terminal 32 and included in the message stacking queue 36 so that the message is arranged for transmission 114. The process returns to await receipt the next incoming call 102.

If required the submission of a return acknowledgment signal 112, the message is recalled from the message memory 42 and provided to a block arrangement of messages in the queue 36 (Figure 1) so that the message is queued for paging transmission on a priority basis 116. The recording is played back to the sender, informing him that he is waiting for a confirmation signal. The processing is suspended until the adoption of a return acknowledgment signal 120 or until the end of the pause 122. The pause is a predetermined time during which the system keeps the sender of the line to await reception of the acknowledgment signal. When this time has ended 122, a message is sent to the sender that no response has been received 124, terminal 32 interrupts process 126, and it starts again initially with a wait for the next incoming call 102. If a confirmation signal 120 is received at the specified time, the acknowledgment signal is analyzed to see whether the assigned security identification code 127. is received. If security ID 127 is not received with the acknowledgment signal, the process returns to wait for another acknowledgment signal 120 or the pause 122 to be received. . For playing a protec ID code prevents errors by verifying that the acknowledgment signal is created in response to the sender. This is desirable as a hospital to obtain a valid confirmation that the doctor has been paged. If security ID 127 is detected, the acknowledgment response signal, a standard message such as "no acknowledgment signal received," or the message created by the pager user is forwarded to the sender 128. The personal call 32 terminates the process 126 and it returns to wait for the next incoming call to be received 102.

According to FIG. 3, the radio pager combination is a wireless telephone transceiver 40 (FIG. 1) according to a preferred embodiment of the invention comprises a personal call receiving line 200, a wireless telephone transceiver 205, and a message and display control path 210. for personal call 200 includes an antenna 212 for receiving signals, for selective call, a radio tuned to the frequency of the personal call channel 214 connected to the antenna for demodulating the signals Selective call, and a decoder for decoding the demodulated signal to recover the page transmitted thereon.

The decoded page is provided to a message processor and display controller 220 for processing. Through conventional operations, the decoded message is stored in the message memory 222 and the user (subscriber) is alerted via a signaling device 224 that a paging message has been received. The user can activate the controllers of the user and the display 226 to output the message from the message memory 222 and display it in the message display 228. The controllers can control the display or change the reception parameters in a known manner.

According to the invention, codes for a particular personal call address or flags added to a single message set the message processor 220 to initiate a telephone call through the wireless telephone transceiver 205 when it is within range of the wireless telephone call station 15 ( fig.1). Therefore, when a warning (alarm) signal is generated, the alarm device 224 alerts the user that a message has been received and, depending on the desired operation, may indicate that a confirmation signal is requested so that the user can initiate a response, or automatically generates a confirmation acknowledgment signal. The acknowledgment signal is generated by activating the cordless telephone transceiver section 205 of the combination radio pager / cordless telephone transceiver 40.

The operation of the wireless telephone transceiver 205 is controlled by a telephone control logic unit 230. The antenna 232 is coupled to a transceiver antenna switch 234 which operates in accordance with the control of the telephone control logic unit 230. The transceiver antenna switch transmission "234 in one position connects the antenna 232 to the radio tuned to the frequency of the telephone channel 236 for receiving radio frequency signals and transmitting the signals to the telephone control logic. In the second position, the transceiver antenna switch 234 connects the antenna 232 to a transmitter tuned to the frequency of the telephone channel 240, which processes the signals received from the telephone control logic device 230 for transmission as radio frequency signals from the antenna 232.

It is possible that speaker 238, a, can be connected to radio 236. to transmitter 240 - microphone 242 for conventional cordless telephone operation. In a possible embodiment, the receiver 236 delivers the audio signal compositions to the speaker 238 and the digital signal components to the telephone control logic 230.

According to the invention, when the wireless telephone transceiver 205 operates in "confirmation" mode, the receiver 236 seeks a signal from the wireless telephone call station 15 (FIG. 1). When the receiving corner 236 determines that the radio pager-wireless telephone transceiver 40 is within the range of station 15, the telephone control logic 230 triggers the transmitter 240 to transmit a call through the call local station 15 to the personal calling terminal 32 (FIG. 1). ). When the terminal 32 answers the acknowledgment call, the processor 220 provides a special code thereto that identifies the specific radio pager 40 that is calling and a message received acknowledgment signal. The acknowledgment signal can be determined by selecting the type of message that was received (t.e.rechevo, numeric or alphanumeric message), the time at which the message was received, whether the message was received with errors or error-free, or determine a custom acknowledgment alert. In addition, the acknowledgment signal may also be used by the personal call terminal 32 to request relaying of an error message.

In FIG. 4, the operation of the personal call message processor 220 according to a preferred embodiment of the invention starts operation 300 with the activation of the radio pager / wireless telephone transceiver 40. The message processing process waits for the reception of a message containing a personal call address code. corresponding to a radio pager 40.

When the assigned personal call address code is received 302, the process determines whether a confirmation signal 304 is requested. If the message is flagged by the acknowledgment message flag block 42 (FIG. 1), a confirmation signal is requested 304. The predetermined code submitted to the address paging can also show that it is exquisite 304 confirmation signal.

If not requiring confirmation signal 304, the message is stored 306 for subsequent removal by the user in accordance with the standard operation of the pager and generates an alarm signal 308 to notify the user that the message was received and remembered. Then the process returns to await the adoption of 302 next message having an address code for peer sonalnoto call.

If the request acknowledgment signal 304, the message is stored 310 and an alert is generated 312. In accordance with the invention generate a signal response for the confirmation 314 including a security ID code assigned to the pager. The acknowledgment signal can be generated automatically or can be taken into account when customized by the user by activating controls 226 or by entering a voice message via microphone 242 (Fig. 3). In addition, the processor 220 can be generated specific response requesting retransmission upon detection of sufficient errors in the received message to indicate that the message may not have been correctly received. The security ID verifies the validity of the acknowledgment signal, confirming that this signal was created in the radio pager / cordless telephone combination 40.

After generating acknowledgment signal 314, processor 220 triggers wireless telephone transceiver 205 in acknowledgment mode 316. With activation 316 of transceiver 205, receiver 236 searches for a local telephone station 318. When a signal from a local telephone station is detected, a wireless telephone connection is established between transceiver 205 and it.

The processor 220 signals the telephone control logic 230 to call up 320 the paging terminal 32 (Figure 1). When the transceiver 205 connects to the terminal 32 via a wireless telephone connection, the generated acknowledgment signal is sent 322 to the terminal 32. The call is terminated 324 and the process returns to wait for the receipt of the next message having a personal call address code set. 302.

Therefore, according to the invention peydzhingsaobshteniya transmitted from a paging terminal and received by the radio pager can be acknowledged via a cordless telephone link between a transceiver coupled to radiopeydazhra and terminal.
