Description
~~~~~_ METHOD OF DEI,IVEIBING PAGING MESSAGES
USING VOICE MAIL
Field of the Invention The field of the invention relates to paging networks and, in specific, paging networks within cellular system.
Background of the Invention Wireless paging networks are known. Such networks typically transmit short paging messages (either audible or display) over wide geographic areas.
Paging receivers (pagers) within such systems are typically constructed to monitor a paging channel for identification codes. Upon receipt of a code the pager compares the received code with an internal code. When the internal code matches the transmitted code the 2 0 pager reproduces the paging message associated with such code on an output device for the benefit of a subscriber.
While such systems may be effective in the market for low-cost, rapid communication, they suffer from 2 5 disadvantages associated with the one-way nature of such transmissions. Where a particular pager is deactivated, or out of range, paging messages directed to that paging receiver may be lost.
Other paging systems have been constructed with 3 0 pagers that acknowledge paging notification messages.
Such pagers are equipped with transmitters used to transmit a page acknowledge message upon detection of a page directed to the responding pager.
Where the system transmits a paging notification ~ 5 and the paging receiver doesn't respond (unit deactivated or out of range) the system periodically retransmits the page. Upon receipt of a paging acknowledgment by the system from the receiver, the system may immediately transmit the paging message 4 0 as well as any other paging messages that have t~ IL
accumulated in a message queue maintained for the pager.
While deferral of message transmission until a page has been acknowledged reduces the incidence of lost messages, other problems may be experienced within such a system. Where a number of messages have accumulated in the system message queue and a page acknowledgment is received by a base site, the base site may immediately transmit all the messages in the queue. The immediate transmission of queued messages may overwhelm the storage capacity of the pager. Also, where a page acknowledge has not been received for an extended period the message queue may become filled, requiring that some messages be over-written resulting in lost information. Because of the importance of paging systems a need exists for a method of delivering paging messages that avoids lost information.
Summary of the Invention A method and means of delivering paging messages in a cellular communication system, such 2 5 method and means c~mprising the means for, and the steps of, paging the communication unit and, upon expiration of a paging period, converting the paging message into a voice mail message.

, , i ~' j D (a _3_ Detailed Description of the Preferred Embodiment The solution to the problem of queuing paging messages lies, conceptually, in removal of the oldest messages from ehe paging queue, converting the messages into voice mail and delivering such voice mail to the paging subscriber through a telephone interconnect. The criteria for removal of paging messages from the queue could be time or queue capacity. A message in the paging queue longer than 15 minutes is not as relevant as a message present for less than 5 minutes. A maximum page period (e.g., 15 minutes) could be set by the subscriber as the criteria for removal and conversion.
Queue capacity could be another parameter used to control conversion. Paging system users with a lower level of service may be paying for a lower capacity queue (e.g., 5 messages). If the number of messages 2 0 entered into the queue within the maximum page period should exceed 5 messages then the oldest messages would be converted to voice mail.
Upon entry of a paging message into voice mail, a voice mail paging request may be transferred back to 2 5 the paging system. The voice mail gage notifies the subscriber of waiting messages. Voice mail notification may, also, be given the subscriber through a local telephone interconnect (e.g., at a place of business).
Under the preferred embodiment a voice mail paging 3 0 request is automatically generated within the voice mail system and transferred back to the paging system. In another embodiment of the invention in which paging and voice mail are part of separate systems a paging message is generated within the paging system notifying 3 5 a paging subscriber that page messages have been converted to voice mail and stored within a voice mail system.
The paging system, upon receipt of such voice mail request, generates a voice mail paging message. The 4 0 voice mail paging message is different from other subscriber paging messages in that voice mail messages -, _4_ are transmitted far less often. Whereas subscriber messages, if undelivered, may be transmitted every 3 minutes, voice mail notification is transmitted every 15 minutes, or once every half-hour. i~oice mail notification also does not change in relation to the number of messages stored in voice mail.
In addition to being transmitted far less often the , voice mail page message provides the benefit of transmitting the same number of page messages, at the same time interval, no matter how many paging ' messages have been converted and stored in voice mail.
Such voice mail page message provides indication of additional older messages, to a user, without system disruption or information loss.
Conversion of paging messages upon transfer from the paging system to the voice mail system occurs within the voice mail system and includes certain formatting changes. Since voice mail systems tend to be interactive (menu controlled) the paging messages is converted into 2 0 a form compatible with such a system. To this end, information relative to time and date of receipt of the page may be combined with the paging message. Paging messages may then be interleaved with other voice mail messages under a last-in-first-out (LIFO) format, first-2 5 in-first-out (FIFO), or; under the preferred embodiment, accessed under a separate voice mail menu entry.
Playback of paging messages, under voice mail, may also be combined with information relative to source and time of receipt.
3 0 As an example, the following audio information may precede an audio representation of the paging message "You received a digital page at 3 pm on October 2, 1992.
The message was 708-555-1212".
Conversion of information within the page message 3 5 may be performed under any of a number of different methods. Paging information may be converted using a voice synthesizer with an audio representation of the paging information stored on a storage medium (e.g., a computer disk). Information within a page message may 4 0 also be stored as an ASCII file within a computer disk ,. :; ; . , ' ' , ::.

Retrieval of paging messages stored under voice mail may be accomplished through the telephone S interconnect at an office, pay phone, etc. or through a cellular telephone carried by the page subscriber.
Paging messages may also be retrieved through a cellular telephone also adapted to receive paging messages through a digital message service (DMS
Subscriber Mobile unit). One such cellular telephone capable of receiving paging messages is the narrowband advance mobile phone service (NAMPS) cellular telephone available from Motorola Inc.
The NAMPS cellular telephone is used under one embodiment of the invention because it is capable of functioning as a digital paging receiver as well as cellular telephone. During active calls by the NAMPS cellular telephone, paging messages may be received through subaudible signaling. (See U.S. Patent #4,984,290, 2 0 Levine, assigned to Motorola, Inc., for an explanation of NAMPS subaudible signaling during an active call). Page acknowledgments from an NAMPS telephone are also returned in the form of subaudible signaling.
During quiescent periods (telephone "on" but no 2 5 active call in progress) the NAMPS telephone functions as do prior art pagers. One exception is that pages are transmitted to the NAMPS unit and acknowledgments are returned on the cellular signaling channel. A display on the NAMPS telephone provides visual indication of 3 0 call back numbers (digital pages) or short text messages (short messages). During periods when the NAMPS
telephone is de-activated, paging messages are queued or converted into voice mail messages.
FIG. I is a block diagram of an NAMPS pager and 35 cellular telephone system (10), generally, in accordance with one embodiment of the invention. Included within such a system { 10) is an electronic mobile exchange (EMX) (20), base site controller (BSC) {24), cellular message center (CMC) (18), console terminals (14 and 4 0 16), and public switch telephone network (PSTN) (22).

FIG. I is a block diagram of an NAMPS pager and 35 cellular telephone system (10), generally, in accordance with one embodiment of the invention. Included within such a system { 10) is an electronic mobile exchange (EMX) (20), base site controller (BSC) {24), cellular message center (CMC) (18), console terminals (14 and 4 0 16), and public switch telephone network (PSTN) (22).
Also shown in FIG. 1 is a DMS Subscriber Mobile unit (12).
EMX (20) may be of the type available from Motorola, Inc. and described in Motorola Instruction Manual No. 68P81054E59 published by Motorola Service Publications, Schaumburg, Ill. EMX (20) is implemented to provide cellular switching functions within a cellular network which is located outside the PSTN (22). EMX
(20) is further coupled to a number of cellular base stations (24) (only one is shown in FIG. 1); one conventional cellular base station (24) may employ transmitters and receivers of the type described in Motorola Instructional Manual NO. 68P810~8E32-A
published by Motorola Service Publications, Schaumburg, Ill.
In addition to call control and switching functions, EMX (20) also provides control for the storage and delivery of paging messages and voice mail between the CMC (18) and DMS Subscriber Mobile Units (12). The 2 0 CMC (I8) may be of the type available from Motorola, Inc. and described in Motorola Instruction Manual No.
68P09212A30 published by Motorola Service Publications, Schaumburg, Ill.
FIG. 3 is a flow chart of system (10) operation 2 5 under one embodiment of the invention. Reference will be made to the flow chart (FIG. 3) as appropriate in understanding the invention.
By way of example, a PSTN Subscriber (23) within the PSTN (22) dials a cellular access number for the DMS
3 0 Subscriber Unit ( 12). The PSTN (22) routes the call to the EMX (20) (42). The EMX (20) causes a call page to be transmitted from each of the BSCs (24) within the system (10) or through the BSC (24) where the DMS
Subscriber Unit (12) has last registered. If the DMS
3 5 Subscriber Unit ( 12) answers (44) the call proceeds as a cellular telephone call. If the Subscriber Unit (12) does not answer (unit turned off or call-in-progress) then the EMX (20) routes (46) the call to the CMC (18).
Within the CMC (18) a message controller (MC) (36, 4 0 FIG. 2) receives the call and presents menu options (48) to the caller from an audio synthesizer (38). The PSTN
~? ~ ~ ~ l~ ~f ~' _7_ subscriber (23) may choose voice mail or paging. If the subscriber (23) chooses (48) paging a memory location is allocated within a page message memory (38) within the CMC (18). 'The MC (36) prompts the subscriber (23) to enter a page message. Upon entry of the page message the entry within the page messages memory (38) is complete and the call is terminated.
Upon completion of the page message a paging request is composed (34) and communicated from the MC (36) to the EMX (20). Upon receipt by the EMX (20), a page message is transmitted (52) through each BSC
(24) for the benefit of the DMS Subscriber Mobile Unit (12). After a page interval (e.g., 3 minutes) the page is repeated.
The page is repeated until the process has been repeated for a maximum page period (e.g., 15 minutes).
When the maximum page period has been exceeded the MC (36) deletes (56) the page from the page message memory (38), converts (60) the message to voice mail 2 0 and stores the message in the voice mail memory (30).
Within the voice mail memory (30) the message is retained until retrieved by the DMS Subscriber Mobile Unit or by the subscriber through some other telephone interconnect. While a voice mail message remains 2 5 within the voice mail memory (30) a voice mail page is composed (34) at regular intervals equal to a voice mail page interval (e.g., 15 minutes). The voice mail page is communicated by the MC (36) to the EMX (20). The EMX
(20), in turn, causes the BSCs (24) to transmit the voice 3 0 mail page to the DMS Subscriber Mobile Unit (12).
Upon receipt of the voice mail page the DMS
Subscriber Mobile Unit (12), as pan of the page, receives the telephone access number of voice mail within the CMC (18). Upon dialing the access number the DMS
3 S Subscriber Mobile Unit (12) is presented with options for retrieving voice mail. Upon retrieval of such voice mail the retrieved mail may be retained or deleted as desired by the DMS Subscriber Mobile Unit (12).
EMX (20) may be of the type available from Motorola, Inc. and described in Motorola Instruction Manual No. 68P81054E59 published by Motorola Service Publications, Schaumburg, Ill. EMX (20) is implemented to provide cellular switching functions within a cellular network which is located outside the PSTN (22). EMX
(20) is further coupled to a number of cellular base stations (24) (only one is shown in FIG. 1); one conventional cellular base station (24) may employ transmitters and receivers of the type described in Motorola Instructional Manual NO. 68P810~8E32-A
published by Motorola Service Publications, Schaumburg, Ill.
In addition to call control and switching functions, EMX (20) also provides control for the storage and delivery of paging messages and voice mail between the CMC (18) and DMS Subscriber Mobile Units (12). The 2 0 CMC (I8) may be of the type available from Motorola, Inc. and described in Motorola Instruction Manual No.
68P09212A30 published by Motorola Service Publications, Schaumburg, Ill.
FIG. 3 is a flow chart of system (10) operation 2 5 under one embodiment of the invention. Reference will be made to the flow chart (FIG. 3) as appropriate in understanding the invention.
By way of example, a PSTN Subscriber (23) within the PSTN (22) dials a cellular access number for the DMS
3 0 Subscriber Unit ( 12). The PSTN (22) routes the call to the EMX (20) (42). The EMX (20) causes a call page to be transmitted from each of the BSCs (24) within the system (10) or through the BSC (24) where the DMS
Subscriber Unit (12) has last registered. If the DMS
3 5 Subscriber Unit ( 12) answers (44) the call proceeds as a cellular telephone call. If the Subscriber Unit (12) does not answer (unit turned off or call-in-progress) then the EMX (20) routes (46) the call to the CMC (18).
Within the CMC (18) a message controller (MC) (36, 4 0 FIG. 2) receives the call and presents menu options (48) to the caller from an audio synthesizer (38). The PSTN
~? ~ ~ ~ l~ ~f ~' _7_ subscriber (23) may choose voice mail or paging. If the subscriber (23) chooses (48) paging a memory location is allocated within a page message memory (38) within the CMC (18). 'The MC (36) prompts the subscriber (23) to enter a page message. Upon entry of the page message the entry within the page messages memory (38) is complete and the call is terminated.
Upon completion of the page message a paging request is composed (34) and communicated from the MC (36) to the EMX (20). Upon receipt by the EMX (20), a page message is transmitted (52) through each BSC
(24) for the benefit of the DMS Subscriber Mobile Unit (12). After a page interval (e.g., 3 minutes) the page is repeated.
The page is repeated until the process has been repeated for a maximum page period (e.g., 15 minutes).
When the maximum page period has been exceeded the MC (36) deletes (56) the page from the page message memory (38), converts (60) the message to voice mail 2 0 and stores the message in the voice mail memory (30).
Within the voice mail memory (30) the message is retained until retrieved by the DMS Subscriber Mobile Unit or by the subscriber through some other telephone interconnect. While a voice mail message remains 2 5 within the voice mail memory (30) a voice mail page is composed (34) at regular intervals equal to a voice mail page interval (e.g., 15 minutes). The voice mail page is communicated by the MC (36) to the EMX (20). The EMX
(20), in turn, causes the BSCs (24) to transmit the voice 3 0 mail page to the DMS Subscriber Mobile Unit (12).
Upon receipt of the voice mail page the DMS
Subscriber Mobile Unit (12), as pan of the page, receives the telephone access number of voice mail within the CMC (18). Upon dialing the access number the DMS
3 S Subscriber Mobile Unit (12) is presented with options for retrieving voice mail. Upon retrieval of such voice mail the retrieved mail may be retained or deleted as desired by the DMS Subscriber Mobile Unit (12).
