Description

TELEPHONE SYSTEM THAT HAS A PRIVATE BASE STATION SUPPORTED BY A COMMERCIAL NETWORK LINE CELL PHONE Field of the Invention This invention relates generally to wireless radiotelephones and, more particularly, to wireless radiotelephones operating with a private base station supported by a landline that can switch to communication with a cellular network.

BACKGROUND OF THE INVENTION Modern cellular telephone systems currently use high frequency, frequency and / or code multiplexed narrow band radio frequency communication techniques in conjunction with large cells to establish and maintain telephone communications . With the popular growth of mobile stations configured to operate in those systems, the user desires greater flexibility to use those mobile stations. One method for providing flexibility to the user and at the same time encouraging greater use of the mobile stations is to provide low-energy private base stations over which a user can register his mobile station and make and receive telephone calls. One REF. 28182 private base station shares the same frequency bands with large cells, but operates at a greatly reduced power level. Also, each private base station has its landline subscriber telephone number through which all incoming and outgoing calls are routed. Although there are currently systems employing private base stations that can support the registration of multiple mobile stations, a call received at a private base station for any of the mobile stations registered with this base station causes all mobile stations registered with the base station to be Alerted in a similar way. Although this type of operation has been generally satisfactory in the past when the probability of only one or two mobile stations would be registered with a private base station at any given time, it is now technically feasible and desirable to provide a system for the operation of a base station private that accommodates many more mobile stations and at the same time provides an alert signal for a mobile station only when an incoming call is being received from this station. Some proposals for improved cellular communications describe several cellular networks working in association with a private base station. U.S. Patent Nos. 5,353.33 and 5,469,496, to Eyry et al., The advanced smart grid system connects and controls the processing of calls to a subscriber's wireless telephone via a home station or wireless communication network . The network uses data to route calls to a current location and provides instruction data to the landline network and / or a mobility controller and extends a special service request to the calling party. In U.S. Patents Nos. 5,127,042 and ,463,674 to Gellig et al., When a wireless cellular telephone is within the range of a wireless base station, telephone calls can be made over the wireless radio channel or transferred from the cellular radio channels to the wireless radio channel. Telephone calls can be made over cellular radio channels or transferred from the wireless radio channel to one of the cellular telephone channels. U.S. Patent No. 5,442,680 to Schellinger, discloses a system that reduces the amount of time consumed in the verification of a sub-area channel of limited coverage area with a personal base station. A signal is generated, which represents the period of time consumed to verify the radio channel. A set value of a verification time value compared to a value of a synchronization signal is compared, and when a value of the verification time equals or exceeds a value of the synchronization signal, the radio channel verification ceases. Other proposals show various cellular and wireless communication systems using a private base station, wherein several mobile stations can communicate with each other through the private base station, and wherein a plurality of base stations transmit distinctive identification signals. None of these proposals of the prior art, however, allows signaling in the cellular network as is common in the public switched telephone network »Many of the special features available only through the local switch and via the public switched telephone network, wired, are not available through the cellular network and through a private base station. Reforming the cellular network to support signaling would be expensive.

Brief Description of the Invention According to the present invention, a residence or small business will now support a private base station and also support the signaling that bypasses the local switch and allows the obvious advantages of signaling in the cellular network such as the one accompanying to the public switched telephone network. For example, a residential private base station can now collect and store incoming call data. A memory unit is dedicated to registering the calling party number (CPN) and then a separate marker in the private base station generates the number through the cellular network after the residential private base station has been switched to the cellular network in response to a signaling code generated from a mobile telephone registered with the private base station. In accordance with the present invention, at least one mobile station communicates with a wireless cellular telephone network. A private base station includes a system for registering a mobile station with the private base station and allowing the communication of a mobile station with a landline telephone network through the private base station. The base station responds to predetermined signaling codes received from a registered mobile station to switch the communication from the private base station to the wireless cellular telephone network. The private base station includes a memory unit for storing call numbers received from a landline network. A dialer retrieves a stored call number and generates calls through the wireless cellular network after receipt of a predetermined signal from a registered mobile station. In another aspect of the invention, the private base station includes at least one stored emergency number that is dialed through the wireless cellular network after receiving an emergency signal. The private base station also includes at least one stored emergency number that is dialed through the landline after receipt of an emergency signal. In any case, an emergency push button, located either on the mobile station or the private base station can be pressed to generate the emergency signal. In still another aspect of the present invention, all calls made to the mobile station within the wireless cellular network can be redirected through the landline to the private base station.

Detailed Description Referring now to FIGURE 1, there is shown a simplified block diagram of a cellular switching system that is part of a wireless cellular telephone network illustrated generally at 9, its logical entities, as well as the relative connection with the public switched telephone network and a private base station. The cellular concept is well known and is generally described in Bell System Techni cal Journal, Volume 58, Number 1, January 1979, and specifically in an article entitled The Cellular Concept by VH MacDonald, on pages 15 to 41 of this daily, the description of which is incorporated here as a reference. Included within the cellular switching system are the mobile stations (MS) 10 and 11, the mobile switching center (MSC) 12, the public switched telephone network (PSTN) 14, a cellular base station (BCS) 13, a register of home location (HLR) 15, a visitor location record (VLR) 16, a visitor location record of the private base station (P-VLR) 30, and a private base station (PBS) 20. A telephone device of the Subscriber station 19 is shown illustratively connected to the public telephone switched network 14 in a well-known manner. In this particular example, the private base station was illustrated as part of a residential location 20a, shown with dotted lines. Mobile stations 10 and 11 are shown contained in residential premises. For clarity, the mobile switching center 12 is illustrated in an illustrative manner connected to the mobile switching center 18 and the operating controller of the network (NOC) 17. The mobile switching center 18 is part of the operation of the total cellular systems and may also have a home location register, a visitor location register, a P-VLR, as well as multiple cellular base stations associated with these. It should be understood that other mobile switching centers can also be part of the cellular system. The network operation controller provides full control and therefore ensures that the operation of the entire cellular system is supported and served. The mobile stations 10 and 11 and the base station 20 are designed to operate in a cellular system in accordance with Interim Standard (IS) -136 of the Association of the Telecommunications Industry (TIA), dated December 1994.

The mobile switching center 12 performs all the switching functions related to the release of a call and is interconnected with the public switched telephone network 14, the home location register 15, the visitor location register 16 and the cellular base station 13. The home location register 15 maintains a database, profile registration and call routing information or an indicator of call routing information for all mobile stations in a particular assigned home area. The visitor location register 16 maintains a database for the routing information of the call or an indicator for the routing information of the call for those mobile stations that are visiting their assigned coverage area. The visitor location register of the private base station 30 performs interconnection functions between a private base station such as station 20, and both, the home location register 15 and the visitor location register 16 to retain routing information from the call and, order or position information recorded by mobile stations that are currently registered with the private base station. The visitor location register of the private base station 30 also responds to the use and operation - of the administration spectrum of the private base station 20. The functions of the location register of the visitor of the private base station 30 may be conveniently summarized as follows: 1. Authorize the operation of a new base station. 2. Download the operation parameters of the private base station and carry out the administration of the operation. 3. Authenticate all calls received from the private station. 4. Perform Registry Notification tasks to the HVLR / VLR when the network update is received from a private station. 5. Perform tasks of inactivation of the mobile station by the HLR / VLR when the cancellation of the network is received from the private base station. Private base station 20 qualifies for time division multiple access cellular operation (TDMA) privately (or non-publicly) under the cellular radio interface IS-136, which allows a mobile cellular station to register with a private base station to receive or originate calls through a landline connected to the network public telephone switchboard instead of through a cellular base station, such as the cellular base station 13, connected in the regular public cellular system. Specifically, this radio interface provides the digital control channel in accordance with the TIA-IS-136.1 and the traffic channels and the control channel in accordance with the TIA-IS-136.2 for communication with the mobile station. An interface or modem interconnection of the private base station and the visitor location register of the private base station is also supported by the interface or radio interconnection. The private base station 20 is limited to a very low level of transmitted power that restricts its coverage area to a very small area. This allows the private base station to reuse the same radio frequency spectrum used by the macrocell systems, while the frequency of use selected by the private base station is different from that of the cell for the regular public or macrocellular system, in whose coverage area is located the private base station. The operating frequency spectrum of the private base station is selected in such a way as to ensure an absence of interference with the macrocellular system. This is achieved by directing the private base station to perform a channel interference scan and measurements before selecting its operating frequencies. While operating in its normal mode awaiting the reception of an incoming call or a pick-up request from a registered mobile station, the private base station 20 continuously broadcasts information from the digital control channel containing the identity and parameters of the system. A mobile station that complies with IS-136 can search for transmission of the control channel of the private base station using a number of techniques. One of these can be based on the prior knowledge of the mobile station of the existence of the private base station. Another may be in response to a user of the mobile station manually addressing the mobile station to search for the private base station. In yet another technique, the mobile station, after finding the control channel of the private base station, automatically proceeds through a series of controlled procedures to obtain registration with the private base station. Once a mobile station, for example, station 10 or 11, obtains a successful registration with the private base station 20, the private base station 20 makes a modem connection with the visitor location register of the private base station 30, to update the temporary line dialing number (TLDN) of the mobile station. The temporary line dialing number in this case will be the landline number (LLN) of the private base station. Accordingly, when an incoming call is directed to a particular mobile station, the information that includes the time line dialing number for this mobile station may be accessed from the visitor location register of the private base station 30 through the registration of domestic location 15 or the visitor location register 16 and the call routed to the LLN of the private base station. It should also be understood that the time line dialing number can be stored in either the home location register 15 or the visitor location register 16 and the mobile switching center 12 so that this TLDN is accessed from this register. The private base station 20 detects the ringing of an incoming call and sends an alert signal or page to the registered mobile station. After the response of the mobile station to the alert signal, the private base station 20, establishes a traffic channel for the mobile station, and generates a pick-up condition for connecting the incoming call through the private base station to the mobile station. The private base station 20 supports the registration of multiple mobile stations and, according to the described embodiment, provides a personalized call release feature to each registered mobile station. To provide the personalized call release feature, during the update of the TLDN by the mobile station in the visitor location register of the private base station 30, additional information elements, ie digits, are added to the TLDN update for distinguish a particular mobile station with the private base station 20. During the registration of a mobile station with the private base station, a unique local address is generated at the private base station. This unique local address can be generated advantageously from the identification number of the mobile station contained in each mobile station or generated from an ordered position assigned by the private base station for each portable station registered with the private base station. Thus, by way of illustrative example of the operation of the ordered position register, the mobile station registering with the private base station 20 is inserted into the registered position 1 by the visitor location register of the private base station 30 and the second mobile station is inserted in the registered position 2 by the visitor location register of the private base station 30, and so on. This ordered position information is advantageously treated as the local single address or a subaddress by the private base station 20 for each mobile station registered with it. Therefore, a different identity of binary digits is obtained for each mobile station that distinguishes it from the other mobile stations registered with the private base station 20. The private base station receives the binary digits describing the order of the registered position of the mobile station. same way as achieved by the release of the caller's ID. The ordered position information is appended to the caller ID message that accompanies an incoming doorbell signal or is appended to the time slot assigned to the calling party ID message when such a message is not present. The switching offices that provide caller ID messages to the telephone station capable of decoding and storing the incoming telephone number are shown or described in U.S. Patent No. 4,277,649, which was granted to D. Sheinbein on July 7, 1981 Knowing the order of the registered position, the private base station together with the help of a user profile of the mobile station stored in the private base station can support additional features, such as 1. Deployment of the name of the calling party in the phone; 2. distinctive alert; 3. Blocking the call; 4. Log of the incoming call; and 4. Telephone answering / message support. Shown in FIGURE 2, there is a high level block diagram of the private base station 20 separated into identifiable circuit sections. A radio frequency (RF) circuit 21 effects the processing of the radio frequency signal. Included in this circuit is a radio frequency receiver section, which receives the radio frequency signal from mobile stations 10 and 11 and, after filtering and proper down-conversion, produces I and Q signals for a RF CODEC 22, which is connected to the RF circuit 21. A section of radio frequency transmission in the RF circuit receives the I and Q signals from the RF CODEC 22, converts those signals to the appropriate radio frequency range and amplifies them for wireless transmission, via the antenna 23. The RF CODEC 22 performs the analog-to-digital (A / D) conversion of the I and Q signals received in the receiving section of the RF circuit 21 and the conversion of digital to analog (D / A) of the I and Q signals provided to the transmitting section of the RF circuit 21. The RF CODEC 22 also performs modulation for the transmission path.

Connected to the RF CODEC 22 is a digital signal processor (DSP) 23, which performs all the processing of the baseband signal for the applications of the private base station. This involves the encoding / decoding of the speech frequency, panning / unzipping of time division multiple access, channel coding / decoding, and other modern portions such as, for example, automatic gain control, symbol synchronization recovery, synchronization , and similar. The DSP 23 also communicates with a microcontroller 24 to exchange control messages. The CODEC 25 of a user performs the conversion of digitally sampled speech frequency signals to analog voice frequency signals and also performs the conversion of speech-to-analog signals to digitally sampled speech frequency signals. Connected to the CODEC 25 of the user is a switch 25a used in the present invention to switch from the private base station to the communication with the wireless cellular network 19 via the line PSTN 14. The switch 25a is connected to a second cellular circuit generally indicated per 100, and in parallel with the RF unit 21 and a hybrid and linear interface interface circuit section 26, which performs the functions required to interconnect the private base station 20 to the public switched telephone network 14 These include functions and circuits such as, for example, off-hook operations, hybrid signals, timbre detection, line termination, hang-up / hang-up signal interconnection signals and the like. The microcontroller 24 performs call processing functions between the private base station 20 and any registered mobile station, thus coition other control functions that are required for the operation of the private base station 20. The LEDs 27 provide visual feedback to a user who enters the private base station. The buttons 28 connect to the microcontroller 24 and are used to make the entries in the private base station 20. Once such an entry, cone is described here later, made by the primary user of the base station who directs this base station upon registering a mobile station for the first time. As shown in FIGURE 2, a memory unit 102 is connected to the microcontroller 24, and stores the call numbers received from a landline network when a mobile unit is not able to accept a call. The memory unit 102 can also store emergency numbers, as well as programs that can be used by the microcontroller of the private base station 24. The microcontroller 24 is programmed to work in conjunction with the minority unit 102., so that predefined signaling codes, similar to the LASS characteristics in a public network, can be generated by a mobile telephone. In accordance with the present invention, the tested base station receives signaling codes from the cellular telephone to enable the signaling functions. As illustrated, the memory unit connects to the second cellular transceiver unit, indicated by the dotted lines of 100 and, more particularly, to a marker unit 104, which generates the called number of the radio frequency transceiver unit 106. , which is connected in an amplifier 108 and the second antenna 110. The second cellular transceiver unit 100 works closely in parallel with the RF unit 21 and is operatively connected to it to work at similar frequencies. The second transceiver unit 100 allows the greatest power generation for operation with the cellular network 9. Additionally, an emergency button 120, typically located on the private base station is connected to the microcontroller, so that after pressing that emergency button 120 , an emergency number is stored and then sent to the cellular network 9. The amplifier 108 provides the aggregate power to the private base station to communicate with the cellular network. Additionally, the mobile units 10, 11, include emergency buttons 10a, which, after being depressed, activate the marker 104, to generate a dialing sequence of emergency numbers stored within the memory unit 102. The private base station it can be designed so that it can be moved and used as a cellular unit if an RJ-11 connection is not available to connect the unit in the wired telephone network 14. The private base station can be programmed so that any emergency number stored can be marked through the wireless cellular telephone network after receipt of an emergency signal if the emergency button is pressed on the mobile telephone station or private base. Additionally, the emergency number stored through the land line. FIGURE 3 illustrates a high-level flow diagram showing an example of the operation of the system. When the mobile station 10 approaches the residential premises 20a containing the private base station 20, the mobile telephone 10 is automatically registered with the private base station (Block 100). At the time of registration, a call issuing signal is sent from the private base station through the landline and the cellular network requesting that all cellular telephone calls made to the mobile station 10 be sent to the private base station via the land line (Block 202). During this time, the memory unit 102 stores several Calling Party Numbers (CPN) (Block 204). The mobile operator then activates a LASS feature, by dialing a service code that is sent to the private base station, ie, AUTO CALLBACK-STAR 69 (* 69). The private base station identifies this service code (Block 208) and retrieves the number of the most recent incoming calling party (Block 210) and then sends those digits to the marking unit 104, connected to the RF unit 106 and the amplifier 108. The switch 25a is activated so that the second transceiver unit 100, transmits the digits on an air interface (Block 212). The network sends the signaling information (received digits) to an MSC 12, and then to a service node (Block 214). The service node identifies a characteristic code and instructs the network to place the call if the line of the called party is unoccupied (Block 216). If the line of the called party is busy, the service node can instruct the network to verify the state of the line of the called party during a defined period of time (Block 218). As soon, this service node detects that the line of the called party is busy, instructs the network to establish the call through a normal call set-up procedure through the wireless network (Block 220). Additionally, the emergency buttons on the private base station or the mobile unit can be used to generate a signal. It should be understood that the switching of the private base station in the cellular network after reception of the signaling codes will preferably occur when only one mobile station is registered with the private base station. However, the operation does not have to operate only in this way.

Referring now to FIGURE 4 of the drawings, general block diagrams of a visitor location record of the private base station 30 are shown. This visitor location record of the private base station 30 may be located geographically away from or colocalized with either a visitor location record or a home location record, with which it receives and provides the information of the private base station. In addition, the functions provided by the visitor location register of the private base station 30 can also be integrated into a visitor location register or a home location register, and therefore such operation is anticipated. The elements used in the registry of the private base station are the computer 300, the modem 330, the interface modules or control interconnection 340, 341 and 342, the disk storage unit 343 and a plurality of databases 310, 330, 335 and 340. The entry to the register of the private base station 30 from a private base station, such as the private base station 20, is provided over two-way communication lines 331 to an assembly of the modem 330. The whole of the Communications modem 330 typically provides data communication between multiple private base stations and the visitor location register of the private base station through the public switched telephone network. To provide this communication, any number of well-known protocols that exist in the industry today can be used. As an example, the protocols of. Modem such as V.22, V.22 bis or Bell 212 are all suitable for communications between the whole of the modem 330 and the private base station through the public switched telephone network. It is also possible to have a packet data protocol that provides the requirement for two-way communications. For example, an X.25 packet data protocol may be used to provide this communication. Also connected to the communications interconnection module 340 are the Integrated Services Digital Network (ISDN) communication lines 332. Although the ISDNs are displayed, other lines may be used appropriately to provide this communication, as well. The ISDN lines 332 are directly connected to the communications interconnection module 340 and allow the visitor location register of the private base station 30 to maintain communications between the home location register 15 and the visitor location register 16. The protocols that can be used to provide this ISDN communications may be, by way of example, either IS-41 or SS7, which are well known in the industry. The data signals received by the modem group 330 on the communication lines 331 and 332 are provided to a communication interconnection module 340. The data received by the interconnection module 340 is coupled to the input / output control module 341 for processing by the computer 300 or for entering or having access to more than one series of databases, illustratively shown as the databases 310, 330, 335 and 345, as well as a disk storage medium 343, via the peripheral control interconnection module 342. The peripheral control interconnection module 342 interconnects the computer 300 and the communication lines to the appropriate ones of a series of databases or data files in accordance with the service or tasks that are being made. Each of these series of databases 310, 330, 335 and 345 contain specific information. For example, the database 310 contains information on frequency assignments of surrounding cellular systems. The database 330 contains information on the operating parameters of private base stations determined by the location of the private base station. The examples of operation parameters of the private base station are its frequency of operation, transmitted power, authorization time and the like. The database 335 contains the order of the mobile station of the position information registered with the private base station and also profiles of the private base station. Examples of private base station profiles are the "Waiting for Call" and the "Calling Subscriber ID" which are provided by the public switched telephone network, and also any private base station location register 30. It should be understood that they can also other databases that provide additional services or tasks with the computer 300 are interconnected via the peripheral control interconnection module 342. The disk store 343 contains operation information that is applicable to the cellular system in general, such as operating parameters that are required to interconnect the visitor location record of the private base station with the home location record and the visitor location record. Contents on the 300 computer are a 304 data processor, random access memory (RAM) 305 and read-only memory (ROM) 306. This processor 304 responds to data input in the input / output control mode 341. And with the entry of the random access memory 305 and the memory alone read 306, the processor 304 also provides the data to the collective conductor of the processor 301 to facilitate data exchanges between the plurality of databases and the communications interconnection module 340 via the peripheral control interconnection module 342. Referring now to to FIGURE 5, there is shown a registration / network update process through which a mobile station, such as mobile station 10, gains access to a private base station, such as the private base station 20. The station Private base initially authorizes the mobile station to obtain registration through it. After such initial authorization, the mobile station remains in the digital control channel. The private base station then seeks authorization to register the mobile station of the visitor location record of the private base station. The encampment of the mobile station on the digital control channel can be terminated by the central private base station if the appropriate authorization of the visiting location of the private base station is not obtained. During the registration process, the home location register 15 or the visitor location register 16 provides a call forwarding number of the visitor location register of the private base station (the LLN of the private base station) for the mobile station.

There are two types of registration processes that take place between the mobile station and the private base station. One is the initial registration of the mobile station with the private base station. In this case, the private base station has no prior knowledge of the mobile station and will not accept its registration attempt unless the primary user of the private base station directs the private base station to do so. This acceptance process can be achieved by the primary user by pressing a registration button and therefore prevent fraudulent registration, for example, by entering a coded sequence of digits, which he or she only knows. Once the mobile station obtains the initial registration, it can automatically obtain the subsequent registration with the private base station after its arrival within the coverage area of the private base station. Thus, this subsequent registration does not require the intervention of the primary user of the private base station in any way. The registration process begins when an authorized mobile station sends a test record (registration sequence) to the private base station. This process of updating the registry / network is summarized below and also illustrated in FIGURE 5. 1. The mobile station sends a test record, which includes the identification of the mobile station (mobile station ID) and the unique serial number (ESN) of the mobile station to the private base station. 2. The private base station sends back the registration acceptance signal to the mobile station. 3. The private base station establishes a modem call to the P-VLR. 4. The private base station performs an authentication task to satisfy the requirements of P-VLR. 5. The P-VLR sends a negative acknowledgment or acknowledgment (ACK / NACK) to the private base station in response. 6. The reception of the NACK responds to cancellations of additional transactions by the private base station and the attempt to register the mobile station will be canceled. Depending on the situation, the private base station may also be directed to shut down and retry the registration at some later time. 7. After receipt of an ACK, the private base station performs an update of the network when the mobile station ID, the mobile station ESN, the land line number as well as the order of the registered position obtained by the mobile station are sent to the P-VLR. The order of the registered position only identifies the mobile station among other mobile stations currently registered within the private base station. 8. The P-VLR sends a Registration Notification to either the HLR or VLR. If the mobile station is in your home cellular coverage area, the notification will be directed to the HLR. Otherwise, the VLR will receive the notification. In the latter case, the HLR for the domestic area of the mobile station will also be notified of the registration notification. 9. The HLR and VLR send an ACK or NACK to the P-VLR. If a NACK is sent, the dialing could depend on a number of factors that depend on the service provider. For example, the provider may find that the mobile station does not have a valid service with it, or a second example could be that the mobile station does not have a valid mobile ID number, or it could also be another similar reason. 10. The P-VLR sends the corresponding ACK or NACK to the private base station. 11. After reception by the ACK or NACK private base station, the modem call is terminated. 12. If a NACK is sent to the private base station by the P-VLR, the private base station sends a registration cancellation to the mobile station. The first mobile station registered with the private base station in this process is assigned the location number of position 1. The following mobile stations registered with the private base station are given corresponding increasing numbers. A corresponding growing number is given to a private base station. A private base station can typically support, by way of example, 10 such registers, although more or less may be desired and the private base station suitably configured to accommodate different numbers. If a new registration request is received appropriately to the mobile station, which exceeds the number assigned to support the registered mobile stations, the least used mobile registration number will become vacant to make room for the new one. Once registered, the mobile station does not need to register again in this particular sense. Once the mobile station attempts to obtain a subsequent registration for the service with the private base station, the registration location number for the mobile station remains unchanged, also assuming a minimum level of periodic use. During the subsequent service provision process, the private base station always sends the visitor location register of the private base station 30, the same registration location number for a particular mobile station. Also, it is undesirable that the exchange of information for a new mobile station registration is very extensive when compared to its subsequent registration with the private base station. Referring now to FIGURE 6, it shows a network cancellation process, in which a pre-established and existing record of a mobile station with a private base station was canceled or terminated. The process of cancellation of the network begins when an authorized mobile station moves outside the coverage area of the private base station or the power of the mobile station is interrupted. When the mobile station moves outside the coverage area of the private base station, the resulting communication loss of the mobile station is detected by the private base station. Also, when the power of the mobile station is interrupted, the mobile station performs a low energy recording. When either of these two events occurs, the process of cancellation of the network is executed with the private base station. Through this process, any call sent to the landline number of the private base station for the mobile station is canceled. The network cancellation process is summarized below and also illustrated in FIGURE 6. 1. The mobile station performs a low energy recording. 2. The private base station establishes a modem call to the P-VLR. 3. The private base station performs an authentication task to satisfy the requirements of the P-VLR. 4. The P-VLR sends an ACK or a NACK in response. 5. If a NACK response is received, the private base station cancels the additional transactions of this particular mobile station. The private base station may also be directed to interrupt or attempt a subsequent authentication attempt. 6. If an ACK response is received, the private base station cancels the network by sending the ID of the mobile station and the ESN of the mobile station to cancel the sending of calls from the telephone calls to the mobile station, which has moved outside the coverage area or whose power was interrupted. 7. The P-VLR sends an inactive signal from the mobile station to the HLR / VLR. 8. The HLR / VLR then sends an ACK or a NACK to the P-VLR. 9. The P-VLR sends an ACK or NACK corresponding to the private base station. 10. After the ACK or NACK is sent to the private base station, the modem call ends. The user of a mobile station may choose to terminate communication with a private base station and reintroduce his mobile station into the cellular system. A mobile station can exercise this option when, for example, the service at the private base station is not available because a single landline connection to the public telephone network is being occupied by another mobile station that is communicating to through the shared private base station. A user of the mobile station can reintroduce the cellular system simply, for example, by pressing a cellular service button, which executes a process where the service with the private base station is terminated and the service with the cellular service provider in the Public cellular system is established. Once the cellular service is established with, for example, the cellular base station 13, shown in FIGURE 6, an update of the network is performed by means of the home location register 15 in the mobile station located in its domestic coverage area or by the visitor location register 16 if the mobile station is outside the domestic coverage area. Next, either of the home location register 15 or visitor location register 16 informs the visitor location register of the private base station 30 that the identified mobile station has returned to the cellular system. The visitor location register of the private base station 30 then stores an inactive signal from the mobile station for the identified mobile station that inactivates or effectively cancels its call forwarding information. Once the landline between the private base station 20 and the public telephone switched network 14 becomes available, it is attempted in processes of cancellation of the network described in FIGURE 6 by the private base station. Since the sending of calls by the identified mobile station has already been canceled in the visitor location register of the private base station 30, in this case by reintroducing the mobile station, the cellular system executing this process only confirms that the The current mobile station is not active with the private base station 20. Referring now to FIGURE 7, there is shown a network process, which provides an incoming call transaction flow for a registered mobile station with a private base station . All incoming calls from each of the mobile stations registered with the private base station are routed to the landline number of the private base station. The transaction flow of the call is summarized below with reference to FIGURE 7. 1. The origin of the call and the ID of the dialed mobile station are received from the public switched telephone network and routed to the MSC. Alternatively, the MSC may receive the origin of the call and the ID of the dialed mobile station of the cellular base station 13 in the public cellular system. 2. The MSC sends a routing request to the HLR of the mobile station (or to the VLR when the mobile station is a visiting station). 3. The HLR sends the Routing Request to the corresponding P-VLR, which contains the registration information for the mobile station. 4. The P-VLR returns the TLDN as well as the order of the registered position to the HLR (or to the VLR when the mobile station is a visiting station) as part of the routing information. In this case, the order of the registered position is defined as a sub-address for the mobile station. 5. The HLR adds the ID of the mobile station and the ESN of the mobile station to the routing information and returns the location request to the MSC, which in turn, sends this information to the PSTN. 6. The call is released by the PSTN, which includes the caller ID of the calling party, to the LLN, the sub-address containing the order of the registered position is also sent together with the caller ID of the subscriber calling the private base station. The private base station then sends a page to the mobile station together with the caller's ID. The paged mobile station is one that corresponds to the order of the registered position. Based on obtaining an order of the position registered by each of the mobile stations, the private base station is able to advantageously offer several intelligent features, which are customized according to the needs of the client. For example, a calling party may have its name displayed in the mobile station for the convenience of the user of the mobile station. The user of a registered mobile station is provided with a separate memory space, located at the private base station for storing a directory of telephone numbers with names associated respectively with the telephone numbers. After receiving an incoming call by a particular mobile station (distinguished by the order of registration position), a calling party that has a number that is equal to one of the numbers stored in the directory will send its name to the station mobile by means of the private base station to deploy it instead of the telephone number. The private base station is capable of providing distinctive alerts for a registered mobile station. The user of a registered mobile station may have, for example, a distinctive ringing sound (chosen from a group of ringing sounds) associated with a particular calling party stored in its directory. The distinctive ring is described illustratively in U.S. Patent No. 4,995,075. When an incoming call comes from the particular calling party, the private base station is able to alert the mobile station using the distinctive ringing sound. The private base station is also capable of providing a number of other advantageous functions based on obtaining a position order recorded for each of the mobile stations. Features such as blocking a call, logging the incoming call, such as described in U.S. Patent No. 5,386,460, and a custom mailbox function is easily provided. For blocking calls, the user has to choose to block an incoming call whose number equals one of the specified numbers stored in the directory. The log of the incoming call is advantageously provided in the private base station of each user of the registered mobile station. And the private base station allows custom greetings to be stored in a mailbox for each of the registered mobile stations. When an incoming call is directed to a particular mobile station and the user of this station does not respond, this personalized greeting is presented to the calling party by means of the private base station. What has been described is merely illustrative of the present invention. Other applications were contemplated to wireless telephones, computers or other communication systems different from the described systems that are within the knowledge of one skilled in the art and can be used without departing from the spirit and scope of the present invention.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention. Having described the invention as above, property is claimed as contained in the following:
