1293003 A7 B7 V. INSTRUCTIONS (1 Background of the Invention 1 = Scope of the Invention The present invention relates generally to telecommunications. More specifically, the present invention relates to systems and methods for determining the clarity of call service options. Further 3 'The present invention relates to a clear system and method for determining call service options in a wireless communication system. 2 · Related technologies Multi-sites Nowadays, various types of multi-channel communication systems have been developed for use in numerous systems. Information transfer between users. Two known technologies used in such multi-access communication systems, including time-multiplexed access (tdma) and frequency division multiple access (fdma), are two technologies. The basic structure design is well known to the industry. However, for example, the spread spectrum modulation technology of the code division multiple access (CDMa) spread spectrum technology, especially for other modulation system users, especially when serving a large number of communication system users. At the time, the system has significant advantages. The use of CDMA technology in a road access communication system is disclosed in U.S. Patent No. 4,901, No. 3, and U.S. Patent Application Serial No. 8/368,57. The former was issued on February 13, 1990, and its name is "spread-frequency multi-channel access communication using satellite or surface transponder". The latter is filed in ^"年丨月#^, whose name is "Methods and apparatus for using the entire spectrum of transmit power in a spread spectrum communication system to track individual recipients' belief in time and energy", both of which are assigned to the assignee of the present application and incorporated herein by reference. The above patent documents disclose multi-access communication, systems, etc. The medium-sized general action or remote system users each use at least one subscriber unit to connect with other system subscribers or other public telephone exchange networks, for example: 5- This paper scale applies to China National Standard (CNS) A4 regulations; ^(210X297 public U" 1293003

Communication. The subscriber unit communicates via a base station or gateway and satellite transponder and using a CDMA spread spectrum type communication system. Today, service options in wireless systems must be resolved before the call is established. Single-station (SSS) and a base station need to know what service options are used on the wireless link. Service options may include, but are not limited to, fax, data, and voice services. The fax service transfers precise copies or copies of files between fax machines over the telephone network. Data services enable the transfer of data between, for example, data processing equipment with data and computer computers. The data modem is a scheme for converting the number of Us into an analog signal and vice versa for transmission over the telephone network. The language service allows the language to be transmitted over the telephone network by converting the sound into a pulse wave. The voice service uses a voice encoder to compress the voice. The language encoder includes an encoder and a decoder. The encoder analyzes the input speech and extracts relevant parameters based on the human speech generation model. The decoder synthesizes the speech using parameters received from the encoder via the transmission channel. Unclearization requires additional resources that can be allocated. Additional resources may include separate catalog numbers for each service. In an action-to-land call situation' (that is, a call that occurs from an active unit using an airborne signal and completed via a landline), a user wishing to connect to a particular service option may be on the phone, data modem, or The fax machine dials a specific preamble number. At this point, the system will queue the previous number and know which type of call will be dialed. In the case of a land-to-mobile call (i.e., a call that occurs via landline and using airborne signals), the user can dial one of the three specific directory numbers if he or she connects to a particular service option.

L293〇〇3 A7 _ B7 V. Inventive Note (3) That is, one of the directory numbers used for fax calls, 'one directory number for data calls, and one directory number for voice calls. This requires an action user to have a separate directory number for each service option. An alternative is in the land-to-action scenario where a user can use a two-phase dial if they need to connect to a particular service option. When using two-stage dialing, after the user obtains the first dial tone, the user dials the first number and then obtains the second dial tone. This first number allows the user to dial into a base station. When the second dial tone is heard, the user dials the second number. This second dial-up connects the user to the desired service option. The need is to use a system and method that provides a clear decision on call service options. Further requirements are provided to provide a clear decision on call service options without the need to allocate additional resources. SUMMARY OF THE INVENTION The present invention can be adapted to the above needs by providing a system and method for making clear definitions of call service options. The invention does not require user intervention. In accordance with the method of the present invention, each wireless call is set by the system and is initially set to voice settings. The detector is then placed in position to detect the tone dedicated to fax and data. If it is detected as a fax or data call, this wireless call can be re-converted to a fax or data call. If not detected as a fax or material call, the wireless call remains as a voice call. The detection of the fax tone can be performed on the call generation side or the call terminal side. The data tone detection is performed only for the calling terminal side. For detecting a fax call, a called tone detector is used on the call terminal side and a call tone detector is used on the call generation side. Called tone for fax machine

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) The present invention is described with respect to illustrative specific examples of specific uses, but it should be understood that the invention is not limited to such specific examples. The skilled person will be able to recognize additional modifications in the application of the teachings provided herein, and the specific implementations within the scope of such modifications and applications and the additional scope of the invention will have significant practical value. The invention can be applied to a variety of different types of wireless communication systems. The preferred mode of operation is implementation in a CDMA system. However, the principles of the present invention can be readily utilized for TDMA or other types of wireless communication systems. The present invention is applicable to a wireless communication system in which at least one of the terminal stations is any one of an active, portable, or fixed wireless subscriber station. A wireless terminal station of this type can be referred to as a "mobile station" for the purposes of the present invention. The traditional non-clear decision of the call service option for a wireless system call requires that the call service option be known prior to the call. Users with a telephone, fax machine, and data modem connected to a personal computer (PC) must have their own telephone directory number in order to identify the call option before the call is established. The present invention is a system and method for determining call service options in a clear manner. The invention does not require user intervention. The present invention eliminates the need to have an individual telephone directory number for each call service option.

This is because fax machines 1 〇 8 and 122 emit a call tone (CNG) 502 when a call is placed or transmitted, or Radiation when terminating or receiving a call A called tone (CED) 5〇4. Called Jinci (CED) 504 is a pure 2100 Hz frequency followed by a V.21 signal. The V.21 signal is a width class of ιτυ_τ ν· series data machine 1 Ding, the V.21 signal for fax transmission is 300 bits per second and has one of the pre-synchronization signals of one of the 'battery mode 0x7e' binary frequency shift keying (bfsk). This 0x7e data mode is transmitted by all fax machines for about 1 second. A fax machine may or may not emit a pure 2100 Hz tone tone, but will always emit a 0x7e batten mode. Therefore, in order to be able to determine the fax call on the detection terminal side in a clear manner, the detector must cut off the called tone data mode and must cut off the 11 kHz call tone on the outgoing side. Both SSS 110 and base station 116 include a detector (not shown). In one embodiment of the invention, each call is initiated as a voice call. The < call will be emitted by the fax machine 122 to a radio call tone of 5 〇 2. The detector in base station i 16 can detect call tone 502.

Invention Description (15) In another embodiment of the present invention, the facsimile detection is on the terminal side and is issued Implemented on the side two sides. Figure 6A is a diagram of a land-to-action call illustrating the detection signals used to determine the data call in a clear manner. The detection of this data call can only be performed on the calling terminal side. This is because the data modem only radiates data tones on the terminal side. Therefore, the data side tone data unit 124 does not radiate the data tone. The information 602 is radiated at the terminal or receiving side. The starting tone of the data call is a V.25 tone. This ν·25 tone is a 21 赫 tone with inversion. The V.25 tone can be followed by the data machine tone. The data machine tone includes the following 'V.21, V.22/V.22 bis, V.32/V.32 bis, etc. without 0x7e mode, but is not limited to these v series standards. Therefore, in order to detect the data call service option on the terminal side in a clear manner, the detector can cut off the V.25 data tone. . The call originating from the data modem 124 will ring the call SSS 110 as described with reference to Figure 。. Sss 110 rings each service option (1〇2, 104 and (10)). The data modem 104 will emit the called tone 602 when answering the material call. The detector in SSS 110 detects the called tone 6〇2. Once the detector indicates that the data call is present, the entire (four) call is either exchanged or re-converted to the data service option. Once the service options are exchanged, the data items are facilitated. Figure 6B is a diagram of a mobile-to-land call, illustrating the detection signals used for clear, incoming calls. The data modem = called, will have the number of vibrations 124 as described above with reference to Figure 2. The data modem 124 will be called when the data call is answered.
