Description of the invention (1) The present invention relates to a wireless telephone system including at least one base station for communication with at least one hand-held phone. Call to the handset service. In this wireless telephone system, a handheld phone and a base station can only be used to exchange electricity. —-> The wireless local loop of the ordinary old telephone in the telephone network is a substitute, or the base station can be a dedicated automatic exchange The wireless extension of the extension, or the base station may be an electrical point radio station connected to a switched telephone network. Similarly, many base stations covering a relatively small area can form a commercial network. With a system like the DECT (Digital European Telecommunications) system, the transfer of inter-cell calls covered by the base station can be completed. The invention also relates to a base station and a handheld telephone used in the system. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs ---- " ----------------------------- (Please read the precautions on the back before filling out this page) A known service in a wireless telephone system in which a base station is installed in a public place is a so-called electrical point service, which allows any user of this electrical point service to access a public switched telephone network. The base station itself has a limited coverage area, such as hundreds of meters.丨 990 European Radio Telecommunications Manual I, pages 91-101 W.H. Tuttlebee and Springer-Verlag have explained such electric point service, as well as wireless business systems and seamless delivery processing. In an electricity point wireless telephone system, one of the electricity point base stations is connected to an analog or digital telephone line, which can be deducted from the calling unit's calling card, borrowing credit cards and authentication procedures during a call, or by other means provided by the network operator. Toll. The problem with point systems is that wireless handset users usually can only make outgoing calls. European Patent Application Ep 02 1 2 76 1 provides an answer to this question. EP 0 212 761 describes a mobile communication system for a combination wireless telephone and a wide area calling system. The communication system allows handheld -4- This paper size applies to China National Standard (CNS) A4 (210X297). Central Ministry of Economic Affairs Printed by the Consumer Bureau of Standards Bureau «167 Preparation A7 B7 V. Description of Invention (2) The phone roams in a large area covered by a wide area calling system. Wide area call systems typically operate in the VHF band (UHF) with 200 km of cells. Here, when the handset is within the range of the base station exclusive to the non-handset, the handset has a built-in message pager to accommodate incoming calls to the handset. When a call is made from a fixed network user or another handset to the handset, the so-called incoming call must be serviced, and the calling system that is playing at the same time sends the call message to the handset's message pager. The call message contains the calling subscriber number And called user number. If there is a call from a fixed network user, the handset that receives and decodes the call message will automatically look for the closest one based on the decoded caller number or when the called user has dialed the caller number on the dial keypad when notified by the call message Within range of the base station. When this base station is found and a radio channel is available, a general call setup procedure is initiated as used for outgoing calls from the handset required for incoming calls. If there is a call from another handset, a more complicated procedure is required. First 'the calling handset is locked to a base station and the called handset is dialed. The call server then sends the call message to the called handset '. This message contains the base station ID-MA (identification code p of the locked handset of the call. Since then, it is the same as the fixed network user used for the call. Procedure. In order to obtain a higher degree of mobility, the base station of the known system here is a car with an S-cell mobile radio communication system, thus allowing roaming during a call. Because the handphone of EP 0212 761 is free of cords A call receiver is required outside the telephone transceiver, so there is no standard wireless telephone handset available in known systems with only a wireless telephone transceiver. Furthermore, this call receiver adds to the cost of a wireless telephone handset.

Description of the invention (3). In the system described in EP 0 212 761, the call charge for incoming calls creates another problem. The proposed solution is based on The battery discharge rate of the phone is used to calculate the cost of the call. This requires the unique shape of the battery supplied by the PTT authority as the sole supplier. Other charging methods proposed for large companies require base stations with special company codes. Purpose of the invention It is to provide a wireless telephone system with an electric point type base station to allow incoming call services to the handsets of this non-exclusive base station. The system is quite simple and cheap. Another purpose is to be in this wireless telephone system. Use a practical standard hand-held phone. Another object of the present invention is to provide a relatively simple call charging method for incoming calls in this system. As a result, the radiotelephone system according to the present invention is characterized in that a base and a brother are connected to each other. A call receiver * 1 ^ optionally receives a call message from a call server coupled to the switched telephone network, the message contains the subscriber number of the incoming call, and is characterized by the base station to which the incoming call is passed and / or the handset includes Call establishment device 'to establish an incoming call based on the subscriber number of the incoming call. Only a relatively small number is required Call receiver, that is, call receiver only in a base station such as an electric point base station or a base station coupled to a PABXs (dedicated automatic exchange extension) 1 When the base station supports the DECT base station (called a protocol called The user number needs a dedicated calling agreement. The call charges can be completed as follows. If it is not a toll-free calling number), the incoming call is paid by the caller. Outgoing barking (or call back) is done by borrowing the following procedure to pay by the callee .Bills can be registered directly from the phone card of the mobile phone. The pulse of billing from PSTN is detected in the base station and -6- Applicable to China National Standard (CNS) Λ4 specification (210X297 mm) '~~' ^^^ 1 -HI ^^^^ 1 ^^^ 1 m ^ i 1. ^^^ 1 m ^^^^ 1 n (ϋ 、》 eJ {Please read the note on the back ^^ item before filling this page) A7 411674 ~ ~ —— V.

The Internet provider provided the phone f'bill 'can be registered by the credit line stored in the mobile phone. Credit and credit cards are posted on individual phones by the credit card provider's debit account. The base station provides access to the credit card provider host. Or, use-general letter = card credit card check for part of the base station lockout process. Payment information will be transferred from the base Q to the service provider's host to complete the call and the account will be charged. If the base station automatically establishes a callback, because the callee cannot decide whether he will answer the call ', the caller should pay for it. This is possible if the caller is logged on to the calling server and the work base station transfers the payment amount to the server at the end of the call. In a specific example of a wireless telephone system according to the present invention, the base station includes a transmitter configured to transmit the received call message to the handset (when the handset is locked to the base station), and the establishment device is included in the handset. Zhongli establishes an outbound call to an incoming call user based on the incoming call user number. This can be achieved by turning the incoming call into an outgoing call by the handset. Printed in another specific example of the wireless telephone system according to the present invention, the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics, the call establishment device is included in the base station to establish an incoming call connected to the incoming call user, and the base station includes a transmitter The transmitter is configured to transmit a call setup call message to the handset to establish a wireless connection to the handset and complete the establishment of an incoming call. First, the connection from the base station to the calling fixed network user is completed, so that the calling user can be notified that the connection to the called user has been established. This needs to be done because the total connection time may exceed the strange time of the calling user, and the call request may not be connected. More specific examples are applied in the scope of the patent application for subsidiary applications, for example, in the application of the paper size of the paper, the China National Standards (CNS) Rule 8 4 ^ ((210X2W mm) printed by the Ministry of Economic Affairs of the Ministry of Economic Affairs, the Bureau of Consumer Standards Cooperatives * 11674 at _B7 _ V. Description of the invention (5) The establishment of an automatic or manual call after a call message is transmitted transparently, or the call receiver and base station are contained in a single housing. In a preferred embodiment of the wireless telephone system according to the present invention, the system is a DECT system combined with a message caller system such as a POCSAG (Postal Code Standardization Advisory Group) system. The DECT system itself may be a microcellular system that supports the delivery as described in Tuttlebee's pages 92-93 and 2 74 of the manual. The base station may include a storage device for storing incoming call messages, and may include a modem connected to an automatic host for charging and authentication. The handset may include a storage device for storing call information if the call is not answered immediately. If it is not answered, the call message is repeated, or the handset obtains the message when it is in standby and can obtain the required information through inquiry.

Description of the invention (9) Frame structure FR. In Fig. 4, it is assumed that the handheld phone HS1 is locked to the base station BS1, and in the call mode, time slots TS4 and TS16 transfer traffic from the base station BS1 to the handheld phone HS1 'and transfer traffic from the handheld phone HS1 to the base, respectively.台 BS1. In addition, the ADPCM Codec 23 shown is consumed by the output voice buffer SB 1. When the incoming call is serviced, s B 1 is used to buffer the ADPCM output to the time slot TS4; ADPCM Codec 23 is coupled to the input voice buffer SB2 '. To buffer the ADPCM input from time slot TS16. FIG. 5 shows a pocSAg call message PM ′ of the radiotelephone system 1 according to the present invention, which includes synchronization information SY, the usual address AS, the isolation symbol Sc, and the data DT. In the example given, a caller with a subscriber number sub A and a fixed network subscriber operating the telephone T1 dials the call server PS and supplies the called subscriber number SUBB of the handset HS1 subscriber number to the call server PS. For the handset HS1, the call is the caller. For example in Germany 'the call server has a front dial of 19. In a wide area call message PM, the called user number SUBB forms the calling address AS, and the calling user number SUBA provided by the call server PS forms part of the data DT. DT may contain other free-form text data τχτ »Therefore the data DT, the text TXT of the calling subscriber number SUBA is transparent to the receiver of this information (in the present invention, the calling receiver PR in the base station BS1). Upon receiving the call message PM, the decoder 16 in the call receiver PR decodes the call message PM. The decoder 16 supplies both the calling subscriber number SUBA and the called subscriber number SUBB to the microcontroller 13 together with any other free-form text such as the text TXT. The microcontroller matches the called subscriber number SUBB to its locked table column.
