Description
Technical Field
The invention belongs to the technical field of communication, in particular to a communication method and a system for adding a paging receiving unit in a common terminal, which are used for carrying out optimized configuration on the existing communication resources, expanding the communication range and ensuring the quick and complete receiving of communication information.
Background
At present, the communication technology includes various communication modes based on a public cellular mobile communication system, a cordless mobile communication system, a wireless trunking mobile communication system and a wired network system, and each communication mode has advantages and disadvantages. For example:
the main advantages of the public honeycomb mobile communication mode are that the mobile range is large, large-range roaming can be realized, but the operation cost is high, and a plurality of regions are difficult to fully cover, so that the mobile communication range of the system terminal is limited, and the integrity of information acquisition cannot be ensured or information loss can be caused.
The wired network (including public telecommunication network) communication mode has the advantages of huge network coverage area and resource scale, but because the user terminal is fixed, the owner must watch the position of the terminal to answer the call in time, thereby causing difficulty in completely acquiring information.
The cordless communication system is used as a wireless extension of a wired public network and directly utilizes various value-added services and huge network coverage areas and resources of a wired telecommunication network, but the mobile communication capability is limited due to the small mobile communication range, so that the integrity of information acquisition cannot be ensured.
In the wireless trunking system, the system is usually an internal private mobile communication system, the terminal is difficult to be directly used as a public communication terminal, and the application function and range of the system are limited, which results in the loss of personal information.
The wireless paging mode, its wireless paging system has low-cost large-scale mobile communication ability, and the signal coverage area and effect are superior to the public honeycomb mobile communication system (especially in villages and towns, mountain areas, lake areas, saliva areas, tourist areas, etc.), to the personal communication service, can almost cover all kinds of user groups in all kinds of areas, if take certain reinforcement measure, can accomplish the ideal state that the information loss rate is zero but because the system only supports one-way text communication at present, thus has limited the communication demand of people in the aspect of real-time voice and two-way digital.
On the other hand, for some communication (network) systems with a switching platform, due to the limitation of system protocols, the capacity of the switching platform must be configured according to the number of terminals, which causes two problems:
(1) when the number of the terminals is increased too fast, the switching platform will be in a saturated state due to the rapidly increased service flow, which results in a great increase of call loss rate. This saturation is usually represented by an unbalanced state, i.e. the size of the traffic flow is represented in a random fashion in a time-area distribution of each day. The conventional solution is to expand the capacity of the switching platform, which not only has high cost, but also has a large influence on the normal communication of the user.
(2) Because the distribution of the service traffic has a random property, the expansion of the switching platform will cause a huge waste of system resources.

Detailed Description
The communication system for realizing the method of the invention comprises: the existing communication network system, wireless paging network system and various communication terminals with built-in wireless paging receiving unit and 'dual-mode function'. The system (network) platform to which the communication terminal belongs includes, but is not limited to, the following types: public cellular mobile communication systems (e.g., GSM, CDMA, etc.); cordless mobile communication systems (e.g., various cordless communication systems such as conventional cordless telephones, DECT technology systems, PHS systems, SCDMA systems, etc.); a wireless trunked mobile communications system; wired network systems (e.g., PSTN network systems, IP network systems, etc.); other various wired/wireless public or private network communication systems.
The main function supporting units of the communication method of the present invention are three parts:
A. the radio paging center includes traditional paging platform, exchange platform and its system function.
B. The wireless paging receiving unit and the corresponding control management function are embedded on the basis of the conventional communication terminal function.
C. The invention supports the system protocol mode of realizing synchronous roaming registration of the original functional terminal and the embedded wireless paging receiving unit in the communication terminal with the 'dual-mode function'.
Wherein the original function terminal is as follows: terminals constructed directly using the relevant communication network system protocol, such as public cellular mobile communication system terminals, cordless communication system terminals, wireless trunking communication system terminals, wired telecommunication terminals, etc. Based on the original function terminal technology, the wireless paging receiving unit is embedded and forms the terminal with 'dual mode function' of the invention. Therefore, the terminal with the dual-mode function is a terminal combination which works under two different communication networks simultaneously, wherein one terminal is the original functional terminal part, and the other terminal is the wireless paging receiving part. The "dual-mode function" terminal can be a "dual-mode function" mobile phone, a "dual-mode function" fixed phone, a "dual-mode function" cordless phone and the like.
Fig. 1 shows a procedure for a conventional call, a called answer and a communication link establishment. The calling of the calling terminal to the called terminal is carried out by calling the switching center of the network system to which the called terminal belongs through the network system to which the calling terminal belongs, the called terminal is called by the switching center according to the calling information, and after the called terminal answers (picks up) the communication link connection between the called terminal and the calling terminal is completed by the switching platform of the network system to which the called terminal belongs.
Fig. 2 shows the process of calling, called answering and communication link establishment implemented by the communication method of the present invention. The calling of calling terminal to called terminal is carried out by calling center of wireless paging receiving unit embedded in called terminal through network system of calling terminal, switching platform of paging center sends information (containing calling telephone number) to embedded wireless paging receiving unit of called terminal according to calling information, after called terminal user receives paging information, according to simple browsing judgment and response to calling information, calling is initiated to paging center corresponding to wireless paging receiving unit embedded in terminal through network system of called terminal, after paging center receives calling of called terminal, communication link connection between called terminal and calling terminal is completed by paging center switching platform.
Several applications of the communication method of the present invention are described below.
Application established in "Call Forwarding" mode
Setting the call forwarding targets of various wireless mobile communication terminals and wired fixed terminals as wireless paging terminals is one of the most common means for ensuring the information acquisition integrity at present. The method has the characteristics of being more direct and convenient than other transfer modes (such as transfer to a fixed terminal, secretary service, voice mail box and the like), and almost achieves where people arrive and where information follows in a nationwide networking wireless paging system. For example, although the cellular phone features a wide-range roaming mobile communication, it is often impossible to achieve effective communication during traveling, and the cellular phone system is very tall and popular in mountainous areas, lake areas and borders, and only the paging system can keep providing good service.
A radio paging receiving terminal (BP machine) is used as a functional unit to be embedded into a public cellular radio mobile terminal, a wired fixed terminal, a cordless communication terminal and a radio cluster terminal, when a user sets call transfer through a (network) system platform to which the communication terminal belongs, the call of the communication terminal is transferred to a paging center to which a radio paging receiving unit embedded in the terminal belongs, and the paging center transmits call information to the embedded radio paging receiving unit of the user terminal in a radio simulcast paging mode and displays the call information. If the communication terminal is a wireless mobile terminal and is positioned in the effective service interval of the system platform, the user can directly communicate with the calling party after receiving the paging information and simply judging the information and pressing a 'reply' key (note: the calling party does not need to hang up to wait for the reply of the other party). If the wireless mobile terminal leaves the service area of the system (network) to which the wireless mobile terminal belongs, the terminal automatically stores the information, and once the user enters the service area to which the terminal belongs, the user is prompted to reply the related call.
If call forwarding is set for the fixed terminal in the home or office at the same time, the terminal embedded with the wireless paging receiving unit will be used as the call target machine for all the personal communication tools (wired type terminal and wireless type terminal) of the user, thereby ensuring the complete acquisition of the user information.
For wired terminals, it is also possible to embed a paging receiving unit to ensure complete acquisition of information. When setting call transfer to the wired terminal and using the embedded paging receiving unit as the transfer target machine, the call for the fixed terminal is transferred to the paging unit, if the user is on site, after checking the information of the calling party, the user can directly communicate with the calling party by pressing the 'reply' key; if the user is not at the terminal site, the paging unit can be used as an information recording device and generates prompt signals for recording information at regular time.
The application mode with more utilization value is as follows: if the user has both the fixed terminal (such as fixed telephone of telecommunication network) and the mobile terminal (such as public cellular wireless mobile communication terminal or cordless mobile communication terminal) embedded with the paging unit, the subscriber number of the paging unit embedded in the fixed terminal can be set to be consistent with the subscriber number of the paging unit embedded in the mobile terminal, and the call initiated by the fixed terminal or the mobile terminal is converted into the mode of the paging receiving unit embedded in the paging center calling terminal according to the call transfer setting of the user through the system platform to which the terminal belongs. Any terminal, upon receiving the call message from the paging center, can simply press the "reply" key to talk or data communicate directly with the caller (without the caller waiting on hook). Therefore, the information can be fundamentally ensured not to be lost.
Here, the paging signal received by the communication terminal is not a call directly initiated by the calling party for the paging terminal user number, but is forwarded by the paging center after call forwarding for a call initiated by a fixed or mobile terminal user number. Thus, the embedded paging unit subscriber number is not available to the public, only as an operational set number when the mobile terminal user needs to ensure that all information follows himself utilizing the call forwarding function.
(II) application established in unified communication signal mode
The application mode supported by the invention can realize that a plurality of terminals use the same user number besides establishing the call collection under the call forwarding mechanism, namely, only one user number is published to the outside no matter what types or number of communication terminals the user has, and a unified communication signal of the user is formed. When a call is made to a user, the user always receives the call in time and enters a two-way communication state in time no matter where the called user is located.
The application mode established in the mode of 'unified communication number' is that a plurality of user numbers (corresponding to the user number of the wireless paging terminal) of wireless paging receiving units embedded in the terminal with the 'dual-mode function' of the invention owned by a user are directly unified into one number and used as communication calling numbers which are externally disclosed, and the user numbers of various original function terminals (such as a honeycomb mobile phone, a family fixed phone and the like) are only disclosed for friends and relatives, so that the conventional calling aiming at the user terminal is changed into the calling aiming at the user unified communication number, and the terminals responding to the calling (in a ringing or other mode) are all terminals owned by the user. That is, the call of user communication signal reaches all terminals configured with embedded wireless paging receiving unit through wireless paging system, all terminals of the same user respond to the call to prompt the user (ringing or other mode), the user can directly reply communication through any terminal responding to the call, the specific operation mode is: after the calling information is simply screened, the calling party decides to enter the communication state immediately, and only a 'reply' key needs to be pressed (the calling party does not need to hang up to wait for the reply).
When all communication terminals owned by the user are the terminals with the 'dual-mode function', the application mode of 'unified user number' can exert the maximum effect, and the ideal state of information acquisition integrity is achieved.
(III) application established in 'balance exchange service flow' mode
For some communication network systems with switching centers, since the time-area distribution of switching traffic is random and unbalanced in practice, configuring the capacity of the switching devices only according to the amount of network terminals results in a huge waste of resources (especially for wired telecommunication networks). It can be seen from the basic mode of the communication mode corresponding to the present invention that the paging center switching platform matched with the present invention adopts low-capacity switching equipment, so that the problems of randomness and unbalanced distribution of switching traffic can be alleviated to a certain extent.
(IV) establishing a wider information acquisition mode
Due to the limited capacity of communication (network) systems, the amount of end users has developed to a certain extent, and the development of data services will put pressure on the overrun of the system design capacity. If a part of data services are completed through the wireless paging system and the simulcast network thereof, not only the investment is saved, the system capacity expansion pressure is relieved, the operation cost of data communication is reduced (based on the low-cost large-range coverage effect of the wireless paging system), but also the application value of the formed huge-scale wireless paging simulcast network system resources can be increased. For example, if the wired telecommunication terminal is embedded in the wireless paging receiving unit, the mode for realizing data communication (including various short message services) greatly saves network line resources compared with the mode for realizing bidirectional data communication on a telecommunication public network by completely utilizing a wired mode.
The following is further illustrated with reference to exemplary embodiments.
Modern communication systems almost have the function of call forwarding value-added service, and if a call forwarding target machine is set as a wireless paging receiving unit embedded in a terminal with a dual-mode function, an ideal communication state of complete information acquisition can be realized. The system for implementing the present invention in call forwarding mode is shown in fig. 3. Wherein,
the called terminal is a 'dual-mode function' terminal of the invention, which is added with a wireless paging receiving unit on the basis of the original function terminal and is matched with a control management unit working cooperatively with the functions of the original terminal. The original functional terminal is as follows: terminals constructed directly using the relevant communication (network) system protocol, such as public cellular mobile communication system terminals, cordless communication system terminals, wireless trunking communication system terminals, wired telecommunication terminals, etc.
The (network) system to which the called terminal belongs refers to the (network) system to which the original functional terminal belongs. For example, if the called terminal is embedded with the wireless paging receiving unit and its control management function on the basis of the public cellular mobile communication system terminal, the (network) system to which the called terminal belongs is the public cellular mobile communication system.
The calling terminal is any type of terminal capable of carrying out remote calls and communications, including the "dual mode" terminal of the additional radio paging receiving unit of the present invention.
The call forwarding service platform means: and the called terminal belongs to a call transfer function system platform owned by the system. The system platform is a value-added service platform (which is currently and generally used as a standard configuration of various communication systems), and allows a user to perform call forwarding setting by using a specified mode (such as a voice operation mode and the like). After the user completes the call forwarding setting on the call forwarding platform of the system to which the terminal belongs, all calls initiated by the user terminal are forwarded to the target terminal appointed by the user by the system to which the terminal belongs.
The figure lists two parts of the paging centre that are relevant to the invention: a paging platform and a switching platform. The paging platform is a system platform which sends paging information to a wireless paging receiving terminal through a paging simulcast network, and the platform is a necessary system for a paging center.
The exchange platform is a part matched with the invention and is used for receiving the calling information of the calling terminal transferred by the system to which the called terminal belongs, completing the corresponding calling processing (such as busy prompt, line connection and maintenance, ringing echo feedback and the like), and then forwarding the calling information to the wireless paging receiving unit embedded in the called terminal through the paging platform and the wireless simulcast network thereof. After the called terminal processes the call information and replies the call, the switching platform receives the replied call and completes the connection between the reply line and the calling line, thereby realizing the line switching between the calling terminal and the called terminal.
As can be seen from the call forwarding application mode flowchart of fig. 4, the basic way to implement information following for the user is that the communication system to which the terminal belongs forwards the call for the user terminal to the paging center through the system platform to which the terminal belongs according to the preset setting, and then the paging center implements simulcast paging according to the roaming registration condition of the paging receiving unit embedded in the terminal. After the user simply browses the calling party information (such as telephone number), the user presses a 'reply' key (the wireless mobile terminal needs to be located within the effective service radius of the system to which the wireless mobile terminal belongs), the paging center completes the line connection between the called terminal and the calling terminal, and then the two parties can enter a communication state.
FIG. 5 is an exemplary application system in the "unified signaling" mode of the present invention, and the working flow thereof is shown in FIG. 6. The implementation method in the "unified signaling" mode of fig. 5 is similar to the implementation method set up in the "call forwarding" application mode, but the called number sent by the calling party is not the communication terminal user number, but the paging receiving unit user number embedded in the terminal. All the terminals owned by the user can be different user numbers or unified user numbers. Under the condition of unifying the subscriber numbers, after the paging center receives the call, the call to the terminal can be completed by adopting three modes:
the first method comprises the following steps: group calling mode, in which all communication terminals performing location registration in a paging center receive paging information and generate a warning tone, and if any one of the terminals is operated to respond, the operation is regarded as the overall completion of the response operation.
And the second method comprises the following steps: paging-in this mode, the paging center sends paging information to all the user terminals performing location registration in turn, and waits for the user to reply paging at regular time.
And the third is that: and (4) a designated mode, in which the paging center collects all calls to a designated terminal according to the preset setting of the user and the terminal completes the response reply operation.
The three calling and answering modes based on unified communication signal are the platform of the present invention with directional exchange function and configured in the paging center.
The directional exchange function is that for the terminal set owned by a certain user, the sub-number is additionally distributed on the basis of using the uniform user number, the protocol mode is the same as that of calling the internal exchange of a certain unit by using a certain wire telephone, and the internal exchange calls the external wire to the internal extension by adopting a mode selected from group calling, round calling and appointed calling according to the setting.
The function item of "sending simulcast paging information according to the calling mode set by the user" in fig. 6 means that the user can perform coding setting on all the wireless paging receiving units embedded in the terminal, and the paging center performs paging calling in one of the three modes of group calling, round calling and designated calling according to the setting of the user.
The "direct reply to page" function is one of the main features of the present invention. The communication method of the invention is based on embedding the wireless paging receiving unit into various communication terminals, and the basic function of the original communication terminal after being embedded into the wireless paging receiving unit is the function of 'directly answering paging' realized under the support of the functional unit and the system protocol matched with the communication mode of the invention, namely when a calling party calls the matched terminal of the invention, the terminal receives and displays the paging information (including the telephone number of the calling party), and a user can directly communicate with the calling party (including real-time voice and data communication) by pressing an 'answer' key after simply browsing the information of the calling party without hanging up to wait for answering after the calling party finishes calling. This "direct reply to page" functionality is consistent in operation form with the manner in which a conventional called terminal operates "off-hook" to respond to a caller. Thus, the "direct reply paging" function forms an important core of the communication scheme of the present invention. With the support of this function, the whole call and communication process is not essentially different from the conventional call and communication process for the user, but the available value is beyond the conventional call and communication mode in many aspects.
The invention relates to a passive directional exchange function unit, which is a basic function unit of an exchange platform positioned in a radio paging system center, and has the main functions of:
1) the switching process of the conventional switching system calls the called terminal according to the calling signaling after receiving the call signal, and completes the link connection between the calling terminal and the called terminal after the called terminal is off-hook. However, the "passive directional exchange" function unit of the invention firstly sends the calling information to the called terminal through the paging platform and the wireless simulcast network thereof, and then receives the call sent by the called terminal through the (network) system to which the called terminal belongs, thereby passively responding and completing the link connection between the calling and the called.
2) "Directional exchange" includes two aspects of functional characteristics: one means that the switching request of the called terminal is passively received, and the request is the continuation of the former calling process, so that the request is directional. The second is that the exchange function unit has the function of supporting the unified communication signal application mode. For multi-terminal users, the 'directional switching' functional unit can adopt one of three calling modes (group calling, round calling and designated calling) to realize the switching function according to the designated mode of the user. Just as a conventional telecom subscriber loop is connected to a subscriber switching device, the caller information can be sent to some part of the terminals of the same internal switching device in a targeted manner. For the present invention, such functional units like the subscriber switching equipment are located at the center of the radio paging system (not at the subscriber side).
The communication mode of the invention, besides establishing the above application mode and its function support unit, needs the related system protocol to support the synchronous roaming of the 'dual-mode' function unit in the matching terminal, to ensure that the wireless paging system center can complete the link connection between the calling terminal and the called terminal in time no matter under the 'call transfer' application mode or the 'unified communication signal' application mode, namely: the called terminal has roaming registration function in the effective service area of the system, and the embedded radio paging receiving unit can also realize roaming registration in the paging center in the same area.
Fig. 7 is a schematic diagram of an exemplary embodiment of a switching platform according to the present invention. The switching platform is one of the main parts of the paging center, and the work flow thereof can refer to fig. 4 and 6. It includes: the system comprises a central control and processing unit, an internal directional exchange database and a roaming registration database which are connected with corresponding ports of the central control and processing unit, and a call receiving platform, a line control unit, a paging information interface, a paging center platform and a paging simulcast network which are sequentially connected, wherein the call receiving platform, the line control unit and the paging information interface are respectively connected with corresponding ports of the central control and processing unit. The main functions are as follows:
in the application mode of 'call transfer', the paging center first keeps the line after receiving the call transferred by the system to which the terminal belongs, then according to the roaming registration inquiry result of the called terminal, the basic information of the calling party is sent to the paging receiving unit embedded in the terminal, then the 'reply' key can be pressed to initiate the call to the corresponding paging center (for the wireless mobile terminal, the terminal should be in the effective service area of the corresponding system at this time), and then the line connection between the calling party and the called party is completed by the exchange function unit matched with the invention configured by the paging center. The functional unit is configured in the paging center, which is embodied by five basic steps of completing forwarding call receiving, line holding, paging forwarding, receiving reply call and line connection.
In the 'unified communication signal' application mode, the paging center receives the call directly sent by the calling initiating terminal through the system (network) system, and the subsequent processes of sending information to the called terminal, receiving the call, completing the line connection and the like are consistent with the process stated in the 'I' item.
As mentioned above, the terminal with "dual mode function" of the present invention is formed by adding a wireless paging receiving unit in the original communication terminal, the paging receiving unit is organically combined with the original terminal part in function, and all original functions of the paging unit and the original terminal are kept unchanged.
Fig. 8 is an embodiment of a "dual mode function" terminal according to the present invention, and the working process thereof can refer to fig. 4 and fig. 6. The terminal shown in fig. 8 is composed of an original terminal part and a wireless paging receiving unit for processing paging information and controlling the terminal to call a paging center. The wireless paging receiving unit consists of a central control processing unit, a keyboard and an LCD display screen which are connected with corresponding ports of the central control processing unit, a paging information receiving unit, a target number processing unit and a functional interface; the paging information receiving and target number processing unit is respectively connected with the input end and the output end of the central control processing unit, and the target number processing unit is connected with the original terminal part through a functional interface.
As shown in the figure, after the terminal receives the call information forwarded by the paging center, the terminal matched with the invention finishes the extraction of the calling party information, the extraction of the number of the paging center sending the page and the completion of the call of the corresponding paging center, and functional units corresponding to three functional steps are integrated into the corresponding communication terminal.
The automatic roaming registration of the "dual mode function" terminal of the present invention is explained as follows. The automatic roaming registration referred to herein refers to the registration of the paging receiving unit embedded in the "dual mode" terminal of the present invention. The original mode is still kept for the mobile roaming registration mode of the original terminal.
(I) Manual roaming registration
The manual roaming registration can be performed for the paging receiving unit embedded in each type of terminal. The registration operates in the same manner as a conventional wireless paging system for the same type of service.
(II) automatic roaming registration in cordless communication System mode
A plurality of wireless local loops formed by cordless base stations and a plurality of terminals are connected together through a network management center to form a local network formed by a cordless system, and a plurality of local networks are connected in a wide area mode to form a wide area network which can realize roaming across regions. In such a mode, the terminal can realize automatic roaming registration, namely once the terminal enters the effective service radius of the system base station, the terminal can finish automatic registration and upload the information to a network management center; and once the system base station leaves the effective service range, the base station cancels the registration record and uploads the registration record to the network management center. For the whole network system, each base station has exact position code information, so that the registered (or de-registered) terminal can complete accurate roaming position registration (or de-registration) after being uploaded to the network management center through the base station, and then the network management center transmits the registration information (or de-registration) to the paging center originally registered by the paging unit embedded in the terminal (the subsequent roaming transfer process is completed in a paging roaming registration processing protocol mode, which is not shown here), thereby completing the roaming registration process of the terminal.
(III) automatic roaming registration in the public cellular mobile communication System mode
Is the terminal regularly showing "whether cross-regional roaming occurred? Once the prompt of ' is generated, the user presses the ' confirm ' key and then completes the input under the prompt of ' inputting roaming area code ' displayed in sequence, and the terminal sends the roaming confirmation and the destination area code information to the paging center in the form of short message, thereby completing the roaming registration.
The automatic roaming registration mode for the embedded paging receiving unit of other public or private mobile communication terminals is the same as that of the public cellular mobile communication terminal, but provided that: the terminal must have the same system network at the roaming local site and support roaming registration of the original terminal under a given agreement.
