Abstract
A method of invoking a telephone user profile is comprised of storing a user call operation profile in a database at a central switching system, dialing from any station in communication with the central switching system a predetermined sequence identifying the user, identifying the user from the sequence and the physical location of the station from which the dialing occurred and storing an indication of that physical location in the database in association with the profile; and accessing the profile for subsequent calls to the directory number and from the station, and using the profile in the processing of the subsequent calls.
Description
FIELD OF THE INVENTION:
This invention relates to telephony and particularly to a method of portably invoking telephone user profiles at variably designated telephone sets S associated with a switching system, the profiles being stored at a central switching system.
BACKGROUND TO THE INVENTION:
A user call operation profile (user profile), contains information pertinent to a telephone call which is specific to a user, such as the identity of a preferred network carrier, speed call information, class of service allowed, and/or other custom calling features. Antiquated equipment could not provide services using user profiles, and therefore to provide such services the antiquated equipment has been required to be replaced with modern equipment which stores such profiles. However even if user profiles are stored, they designate a particular piece of station apparatus (hereinbelow referred to as a telephone set), which is designated by a telephone number.
If a user wishes to temporarily or permanently move to a different physical location and use a different telephone set, either he has been restricted to using the profile associated with that telephone set, or the entire user profile for the different telephone set must be reprogrammed.
Another alternative to offer custom calling features to a remote telephone is to use a centrexJ~
service, in which remote lines are connected directly to a Centrex central switching system. However this creates additional problems and cost, since there may be a significant number of calls desired between users at a remote location, and all such calls must be routed through the CentrexTM system. Thus a considerable number of Centrex lines must be used, whereas practically they L C TM _ Trade Mark *
2U8112.5 may all be needed to handle the traffic. Thus it is impossible to obtain the advantages of line concentration.
In addition, portability of user profiles can be effected S only with reprogramming for each telephone set.
SUMMARY OF THE PRESENT lNv~NllON:
In the present invention, users at a remote location may utilize an in~Ypencive or antiquated remote switching system which does not store user profiles, yet provides the ability to not only offer custom calling features, but also portability of the user profiles from telephone set to telephone set connected to the remote switching system, without requiring reprogramming of the user profile for the telephone set at the new physical location of a user.
In accordance with an embodiment of the invention, a method of invoking a telephone user profile comprising: storing a user call operation profile in a datAhAce in communication with a central switching system, providing from any station in communication with said central switching system a predetermined sequence identifying the user, identifying the user from the sequence and identifying the physical location of the station from which the dialing occurred without the user dialing its line 2S number and storing an indication of that physical location in said database in association with said profile; and accessing said profile for subsequent calls to a directory number associated with the user and distinct from a telephone line and from said station, and using said profile in the processing of said subsequent calls.
The invention can be implemented in either of at least two ways. Either the remote switching system recognizes a prefix digit or group of digits (e.g. the numeral 9) which designate that a call is to be made 3S from a local telephone to a telephone line or trunk connected to the central switching system, which causes the remote switching system to connect the user line 208112~
-directly to the trunk leading to the central system which controls further processing of the call, or by merely going off-hook, the local user is connected directly to the trunk, and subsequent digits are S received directly by the central switching system, controlling either an outgoing call thereby, after retrieving the user profile from its database or controlling the remote switch to provide the custom calling features according to the user profile for an intra-office or an inter-office call, e.g. prefixing outgoing dialed digits with a network carrier number, etc.
Incoming calls to the remote switching system and the user telephone set are controlled by the central switching system after retrieving the user profile including the physical location of the telephone set (line) on the remote switching system, from the database in response to receiving the dialed digits.
Another embodiment of the invention, is as noted in the first embodiment, but in which a subsequent call is made to a telephone number at the remote switching system wherein the remote switching system is connected to the central switching system via at least one trunk, further including receiving a call to the user telephone directory number via the central switching system, accessing the database and retrieving the profile and physical location data using the directory number dialed, and supervising the completion and process of the call using the profile, to the physical location.
Another embodiment is as noted in the first embodiment, but in which a subsequent call is made from a calling line connected to a remote switching system wherein the remote switching system is connected to the central switching system via at least one trunk, wherein the trunk is an ANI trunk, the user seizing the calling line, and dialing digits representing a call to or S through the central switching system, recognizing a first digit or group of the dialed digits as an outgoing call to or through the central switching system, recognizing the physical location number of the calling line, at the central switching system and retrieving the profile, and controlling subsequent processing of the call by the central switching system using the profile.
Another embodiment is as noted in the first emhoAiment, but in which a subsequent call is made from a calling line connected to a remote switching system wherein the remote switching system is connected to the central switching system via at least one trunk, wherein the trunk is an ANI trunk, the user seizing the calling line, recognizing the physical location number of the calling line at the central switching system and retrieving the profile, and controlling subsequent processing of the call by the central switching system using the profile.
In accordance with another embodiment, a method of invoking a telephone user profile is comprised of storing in a database a user telephone service profile containing a directory number of a user, in association with a telephone set line location, receiving a command to change the telephone set line location associated with the user profile, and changing the line location in the database in response to the command, retrieving the profile and changed telephone set line location upon receipt of a request for .~
- 208 11~5 - 4a -completion of a call to the directory number, and completing the call to a telephone set at the changed line location.
In accordance with another emho~iment, a method of invoking a telephone user profile comprising:
storing in a database a user telephone service profile containing a directory number of a user, in association with a telephone set line location, receiving a command to change the telephone set line location associated with said user profile, and changing said line location in the database in response to said command, retrieving said profile upon receipt of a request for making a call from said telephone set, and completing the outgoing call using the new profile retrieved.
Preferably the ANI trunk is a CAMA MF ANI
trunk.
s -BRIEF INTRODUCTION TO THE DRAWINGS:
A better understanding of the invention will be obtained by reference to the detailed description below, in conjunction with the following drawings, in which:
Figure 1 is a block diagram of a system which can be used to implement the present invention.
DETAILED DESCRIPTION OF THE INVENTION:
Turning to Figure 1, plural user telephone lines lA, lN are connected to a remote switching system 3. The remote switching system has at least one trunk 5 preferably a CAMA MF ANI (centralized automatic message accounting, multi-frequency, automatic number identification) connected to a CAMA MF ANI interface 7 in peripheral circuit 9 of a central switching system 11. Peripheral circuits 9 are connected to message and circuit switches 13 and 15 respectively of a peripheral controller 17 of the central switching system. The peripheral controller message switches are connected to a main system message switch 19 which communicates with a central switching system controller 21 via a main system bus 23. The peripheral controller circuit switches 15 are connected to a main system circuit switch 25, which communicates with controller 21 via bus 23. Controller 21 contains a central processing unit, a memory containing operation programs, etc. The peripheral circuits 19 contain line circuits, trunks, etc. e.g. which connect to local telephone sets 27, network trunks 29, etc.
A central switching system containing peripheral circuits 9, message switches 19 and 13, circuit switches 15 and 25, bus 23 and controller 21 can be e.g. as in the telephone system sold by Mitel Corporation as GX5000TM. The remote switching system can be a remote PABX, which can be antiquated equipment such as a step switch switching system, a crossbar switching system such as No. 5 Crossbar, or a modern program controlled system such as SX2000~, GX5000~, sold by Mitel Corporation, etc.
In accordance with the present invention a database 31 is stored in a memory which is connected to bus 23. The database contains two tables, designated Table 1 and Table 2. Table 1 is a device activity map, and has an entry associated with each physical device, which contains the state of the device and current user data. The current user data is comprised of call record data for the call, and the user data associated with it.
The call record data includes information about the current call and is a dynamic data structure. The user data is static, and contains the data programmed in by the customer for a particular phone number, the user profile.
In the present invention, fixed association between the telephone number and the particular physical telephone is broken; the particular telephone number is instead associated with the customer. Therefore what is programmed in by the customer for a particular telephone number relates to his own personal profile.
Table 2 contains the physical location (the particular telephone), currently being used by the customer's telephone number. Under control of controller 21, the two tables are updated dynamically, thus assigning a user, with the user's profile including the user's telephone number, to a physical telephone.
During the process of a call, the controller accesses the tables of the database, associating the user profile data with the location of a physical telephone (e.g. the particular line associated with particular remote switching system 3.
The user profile data contains at least a personal access code and directory number of the user.
It also contains at least one, and likely all of data containing features and restrictions such as call forwarding, information, class of service, class of restriction, do not disturb settings, ring type, pick-up group number, interconnect number, call trace information, disconnect data, speed call information, network carrier numbers, etc. Each user having a particular telephone number has its own user profile characterized by the above.
The remote switching system 3 performs intra-office calls and interconnects telephone sets lA-lN in a well known manner. This can be, for example, under full control of the remote switching system 3. However it is possible that remote switching system 3 is at least partly controlled by the central switching system 11, in a manner described in Canadian patent application serial number 2,052,498 filed September 30th, 1991, inventors Kevin Johnson et al.
A user call operation profile is stored in database 31, in Tables 1 and 2, input either from a terminal 33 connected to bus 23 at the central switching system, or by a remote controlling means, or by updating the database from data stored on a floppy disk or the like.
When a user at telephone set lA wishes to temporarily move to a different physical location where access is made to telephone set lN, telephone set lN is taken off hook and the user inputs a sequence in some way, such as dialing an access code, followed by his identifying directory (telephone) number, followed by his personal account code. The access code is recognized by switching system 3 as designating a call for central switching system 11. The digits dialed are transmitted along trunk 5 into switching system 11.
This invention relates to telephony and particularly to a method of portably invoking telephone user profiles at variably designated telephone sets S associated with a switching system, the profiles being stored at a central switching system.

s -BRIEF INTRODUCTION TO THE DRAWINGS:
A better understanding of the invention will be obtained by reference to the detailed description below, in conjunction with the following drawings, in which:
Figure 1 is a block diagram of a system which can be used to implement the present invention.
DETAILED DESCRIPTION OF THE INVENTION:
Turning to Figure 1, plural user telephone lines lA, lN are connected to a remote switching system 3. The remote switching system has at least one trunk 5 preferably a CAMA MF ANI (centralized automatic message accounting, multi-frequency, automatic number identification) connected to a CAMA MF ANI interface 7 in peripheral circuit 9 of a central switching system 11. Peripheral circuits 9 are connected to message and circuit switches 13 and 15 respectively of a peripheral controller 17 of the central switching system. The peripheral controller message switches are connected to a main system message switch 19 which communicates with a central switching system controller 21 via a main system bus 23. The peripheral controller circuit switches 15 are connected to a main system circuit switch 25, which communicates with controller 21 via bus 23. Controller 21 contains a central processing unit, a memory containing operation programs, etc. The peripheral circuits 19 contain line circuits, trunks, etc. e.g. which connect to local telephone sets 27, network trunks 29, etc.
A central switching system containing peripheral circuits 9, message switches 19 and 13, circuit switches 15 and 25, bus 23 and controller 21 can be e.g. as in the telephone system sold by Mitel Corporation as GX5000TM. The remote switching system can be a remote PABX, which can be antiquated equipment such as a step switch switching system, a crossbar switching system such as No. 5 Crossbar, or a modern program controlled system such as SX2000~, GX5000~, sold by Mitel Corporation, etc.
In accordance with the present invention a database 31 is stored in a memory which is connected to bus 23. The database contains two tables, designated Table 1 and Table 2. Table 1 is a device activity map, and has an entry associated with each physical device, which contains the state of the device and current user data. The current user data is comprised of call record data for the call, and the user data associated with it.
The call record data includes information about the current call and is a dynamic data structure. The user data is static, and contains the data programmed in by the customer for a particular phone number, the user profile.
In the present invention, fixed association between the telephone number and the particular physical telephone is broken; the particular telephone number is instead associated with the customer. Therefore what is programmed in by the customer for a particular telephone number relates to his own personal profile.
Table 2 contains the physical location (the particular telephone), currently being used by the customer's telephone number. Under control of controller 21, the two tables are updated dynamically, thus assigning a user, with the user's profile including the user's telephone number, to a physical telephone.
During the process of a call, the controller accesses the tables of the database, associating the user profile data with the location of a physical telephone (e.g. the particular line associated with particular remote switching system 3.
The user profile data contains at least a personal access code and directory number of the user.
It also contains at least one, and likely all of data containing features and restrictions such as call forwarding, information, class of service, class of restriction, do not disturb settings, ring type, pick-up group number, interconnect number, call trace information, disconnect data, speed call information, network carrier numbers, etc. Each user having a particular telephone number has its own user profile characterized by the above.
The remote switching system 3 performs intra-office calls and interconnects telephone sets lA-lN in a well known manner. This can be, for example, under full control of the remote switching system 3. However it is possible that remote switching system 3 is at least partly controlled by the central switching system 11, in a manner described in Canadian patent application serial number 2,052,498 filed September 30th, 1991, inventors Kevin Johnson et al.
A user call operation profile is stored in database 31, in Tables 1 and 2, input either from a terminal 33 connected to bus 23 at the central switching system, or by a remote controlling means, or by updating the database from data stored on a floppy disk or the like.
When a user at telephone set lA wishes to temporarily move to a different physical location where access is made to telephone set lN, telephone set lN is taken off hook and the user inputs a sequence in some way, such as dialing an access code, followed by his identifying directory (telephone) number, followed by his personal account code. The access code is recognized by switching system 3 as designating a call for central switching system 11. The digits dialed are transmitted along trunk 5 into switching system 11.
2~81125 The peripheral controller, receiving the dialed digits sends a message via a message switches 13 and 19 to controller 21. Controller 21 accesses database 31. In the meantime ANI interface 7 has recognized the line to S which telephone set lN is connected; this information is passed via the message switches to the controller 21 which, using the personal account code as authorization, and the dialed telephone number as a match indicator to the user profile record, stores the new physical location of the user in Table 2, associated with the user profile stored in Table 1.
Now all calls designated for the particular telephone number of the user, as stored in Table 1, will be directed to the line circuit associated with lS telephone circuit lN, rather than the line circuit associated with telephone set lA, and the features and services of the user formerly associated with telephone set lA will be associated with each call to that user's directory number. For subsequent calls to that user's directory number or from the newly designated telephone, the user's profile will be used in the processing of subsequent calls.
Assume now that there is an incoming call via system 11 from the network via a trunk 29 (or from system 3) or from telephone set 27 connected to system 11, to the user. The telephone directory number digits are received at one of the peripherals 9 and a message is sent via message switches 13 and 19 to controller 21.
Controller 21 accesses the database 31 for the directory number and retrieves the physical location of the called user as well as the user profile. The controller then seizes an outgoing trunk e.g. trunk 5, sending messages via message switches 19 and 13 and peripheral controller 9 in a control channel to a controller in remote switching system 3, or by signalling via the seized trunks to system 3 to ring telephone set lN rather than telephone set lA. After telephone set lN goes off hook, answering the call, the call is processed in the normal way, subject to any restrictions or features of the S called user profile stored in the user record of database 31.
If a call is to be made from a telephone set connected to the remote switching system 3, digits representing the call to or through the central switching system are dialed. The remote switching system 3 recognizes a prefix, such as the numeral 9, and seizes trunk 5. The ANI interface 7 in peripheral circuit 9 recognizes the physical location of the telephone set from which the call is being initiated, IS and provides that data to controller 21 through message switches 13 and 19. Controller 21 accesses the database 31, and retrieves the user profile of the calling party.
The profile is used by the controller 21 to control the call and to provide features. For example, if the call is an outgoing call, the controller 21 can cause the peripheral circuit to seize an outgoing trunk to a particular network carrier as designated in the user profile, and if necessary to outpulse or MF signal prefix digits.
It should be noted that at least some lines connected to remote switching system 3 could alternatively be connected to peripheral circuits 9 directly, or immediately upon going off-hook through remote central switching 3, the latter for example if remote switching system 3 is a key telephone system. In such cases the peripheral circuit interfaces will recognize the physical location, i.e. the particular telephone set which is being used immediately, without prefix or access digits being dialed from the remote telephone set lA-lN, allowing the controller 21 to , 2o8ll25 retrieve the user profile from the database 31 as soon as the line has been identified by ANI interface 7. In these cases dial tone is provided from switching system 11 .
S It should be noted that since the user profiles are stored at the central switching system, the benefits of the invention can be provided to telephone sets connected to plural remote switching systems which connect to central switching system 11. The various users can change their locations and use different telephone sets without having to reprogram the database 31 while retaining their user profiles and resulting service; the only data which is changed is the physical location indicator in Table 2.
In addition, the remote switching systems provide both a remote intra-office switching function, and a concentration function; much fewer numbers of trunks between the switching systems are required than the total number of lines, which is a significant advantage over Centrex systems.
It will be recognized from an understanding of the above that content of the database 31 for each user can be modified in other ways. For example, the personal access code of any user could be changed for security purposes, e.g. by dialing a prefix code followed by the old personal access code followed by the new personal access code (twice for certainty). In a manner as described above the controller 21 recognizes the changed personal access code and stores it in Table 1 of database 31. This allows the user to modify his personal access code "password" against his directory number. Other kinds of codes could also be entered by the user, such as a "cancel" code for features, etc.
It will recognized that more than one user can be registered to one telephone set at the same time, , 2081125 -although a particular user can only be registered to one telephone set at a time. If a second registration is made of a user to a different telephone set, the controller 21 performs an automatic registration cancel S for the previous telephone set.
A person understanding this invention may now conceive of alternative structures and embodiments or variations of the above. All of those which fall within the scope of the claims appended hereto are considered to be part of the present invention.
Now all calls designated for the particular telephone number of the user, as stored in Table 1, will be directed to the line circuit associated with lS telephone circuit lN, rather than the line circuit associated with telephone set lA, and the features and services of the user formerly associated with telephone set lA will be associated with each call to that user's directory number. For subsequent calls to that user's directory number or from the newly designated telephone, the user's profile will be used in the processing of subsequent calls.
Assume now that there is an incoming call via system 11 from the network via a trunk 29 (or from system 3) or from telephone set 27 connected to system 11, to the user. The telephone directory number digits are received at one of the peripherals 9 and a message is sent via message switches 13 and 19 to controller 21.
Controller 21 accesses the database 31 for the directory number and retrieves the physical location of the called user as well as the user profile. The controller then seizes an outgoing trunk e.g. trunk 5, sending messages via message switches 19 and 13 and peripheral controller 9 in a control channel to a controller in remote switching system 3, or by signalling via the seized trunks to system 3 to ring telephone set lN rather than telephone set lA. After telephone set lN goes off hook, answering the call, the call is processed in the normal way, subject to any restrictions or features of the S called user profile stored in the user record of database 31.
If a call is to be made from a telephone set connected to the remote switching system 3, digits representing the call to or through the central switching system are dialed. The remote switching system 3 recognizes a prefix, such as the numeral 9, and seizes trunk 5. The ANI interface 7 in peripheral circuit 9 recognizes the physical location of the telephone set from which the call is being initiated, IS and provides that data to controller 21 through message switches 13 and 19. Controller 21 accesses the database 31, and retrieves the user profile of the calling party.
The profile is used by the controller 21 to control the call and to provide features. For example, if the call is an outgoing call, the controller 21 can cause the peripheral circuit to seize an outgoing trunk to a particular network carrier as designated in the user profile, and if necessary to outpulse or MF signal prefix digits.
It should be noted that at least some lines connected to remote switching system 3 could alternatively be connected to peripheral circuits 9 directly, or immediately upon going off-hook through remote central switching 3, the latter for example if remote switching system 3 is a key telephone system. In such cases the peripheral circuit interfaces will recognize the physical location, i.e. the particular telephone set which is being used immediately, without prefix or access digits being dialed from the remote telephone set lA-lN, allowing the controller 21 to , 2o8ll25 retrieve the user profile from the database 31 as soon as the line has been identified by ANI interface 7. In these cases dial tone is provided from switching system 11 .
S It should be noted that since the user profiles are stored at the central switching system, the benefits of the invention can be provided to telephone sets connected to plural remote switching systems which connect to central switching system 11. The various users can change their locations and use different telephone sets without having to reprogram the database 31 while retaining their user profiles and resulting service; the only data which is changed is the physical location indicator in Table 2.
In addition, the remote switching systems provide both a remote intra-office switching function, and a concentration function; much fewer numbers of trunks between the switching systems are required than the total number of lines, which is a significant advantage over Centrex systems.
It will be recognized from an understanding of the above that content of the database 31 for each user can be modified in other ways. For example, the personal access code of any user could be changed for security purposes, e.g. by dialing a prefix code followed by the old personal access code followed by the new personal access code (twice for certainty). In a manner as described above the controller 21 recognizes the changed personal access code and stores it in Table 1 of database 31. This allows the user to modify his personal access code "password" against his directory number. Other kinds of codes could also be entered by the user, such as a "cancel" code for features, etc.
It will recognized that more than one user can be registered to one telephone set at the same time, , 2081125 -although a particular user can only be registered to one telephone set at a time. If a second registration is made of a user to a different telephone set, the controller 21 performs an automatic registration cancel S for the previous telephone set.
A person understanding this invention may now conceive of alternative structures and embodiments or variations of the above. All of those which fall within the scope of the claims appended hereto are considered to be part of the present invention.
