BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication link control technique for suppressing electromagnetic interference, increasing battery life, and improving traffic capability in mobile communication.

Mobile communication is operated by frequency division multiple access (FDMA), time division multiple access (TDMA) or code division multiple access (CDMA), thereby securing mobility and communication paths of terminals. Is a well-known fact, and in the case of satellite communication, a space division multiple access (SDMA) method using a beam is added thereto.

Such mobile communication, that is, cellular, trunked radio system (TRS), satellite communication (Satellite Phone), etc. was originally developed to increase the location mobility and frequency utilization of the terminal station. For example, the base station and the terminal device periodically perform radio communication with each other independently of the call path in any one cell, and have a means for confirming the position of the terminal station in which communication zone. By operating the HLR (Home Location Register) and the VLR (Visit Location Register), hand-off and roaming as well as mutual call are possible. For example, in the case of CDMA, a wireless channel called Paging Channel. Conventional competitive access (CSMA / CA; Carrier Sensed Multiple Access / Collision Avoidance, Sloted CSMA, Sloted ALOHA) or polling, i.e. Also it is known as a polling call signal or call) the location registration or the like, and performs a communication confirmation and call processing.

The contention access method (CSMA / CA, etc.) is mainly applied when the terminal initially registers the location by turning on the power, and the polling method (Polling) is applied to continuous confirmation communication at a fixed interval of about 6 seconds thereafter. It is known to apply, but depending on the system, it may be appropriately selected or mixed in various ways.

Hereinafter, in the present invention, the communication means is abbreviated to be referred to as confirmation communication.

As described above, the confirmation communication is very beneficial in terms of ensuring the mobility of the terminal. In fact, the mobile communication is realized based on this information communication technology (IT). However, in view of the confirmation communication only for positioning or network synchronization, As a result, problems caused by the usual network maintenance function irrelevant to the user's will will be an unresolved task in terms of biotechnology (BT) or environmental technology (ET).

Summarizing the problems caused by the confirmation communication, even though the battery of the mobile phone is much larger than a typical portable radio receiver, the non-call ready state does not reach 1/1000 of the radio receiver. The transmission power, which is the main cause of consumption, becomes electromagnetic waves, which adversely affects electromagnetic interference and spatial noise. When many terminals are concentrated in one cell, the traffic capacity is reduced due to confirmation communication. It is summarized in that it adversely affects.

Moreover, despite the fact that mobile phones are equipped with hands-free or earphones, when not in use, they are inevitably kept in close contact with the human body (such as storage of australia) .In this situation of close contact, electromagnetic waves are continuously emitted regardless of the user's will. In spite of the verification of the risk, the necessity of actively researching as a new technology in terms of eliminating the causes arises.

On the other hand, the present invention fundamentally solves the unresolved problems in terms of the biotechnology (BT) and environmental technology (ET) as a simple communication link algorithm of the following information and communication technology.

A first object of the present invention is to provide a means for solving the electromagnetic interference, which is considered harmful or harmful to the human body, as a communication link control method.

The second object of the present invention is to minimize the transmission power in the standby of the mobile phone to significantly increase the use time of the battery and to improve the traffic capacity of the communication channel.

The third object of the present invention is to provide a means that does not interfere with the guarantee of the existing mobility even if the confirmation communication between the base station and the terminal device is minimized, and also by cutting-edge IT by limiting the control function separate from the normal call channel control The objective is to provide a means of constructing a technology and interlocking system.

According to the present invention for this purpose, the terminal apparatus sets various communication parameters to the signal periodically transmitted by the base station, but the terminal apparatus periodically transmits as long as the communication parameters of the base station are in a stable state where the communication parameters of the base station are not particularly changed. Provide a means for automatically pausing the positioning communication period or stopping the positioning communication period to stop the action,

In addition, the present invention, the base station and the terminal station is operated separately by such means, or "the base station and the terminal station automatic setting situation so that the base station and the terminal station can accurately recognize the situation that the communication link is changed to the other party Alert each other to provide a means of interoperating with each other.

In another aspect, the present invention provides a means for interlocking the global positioning system (GPS) and the communication link function of the terminal station to determine whether the mobile terminal is moved after location registration and to automatically control the confirmation communication interval, It also provides a means to hybridize the parameter analysis function included in the signal of the base station to it if necessary.

Hereinafter, the technical principle will be described in detail with reference to an embodiment of the present invention.

However, the embodiment and the operation described in the following is merely described by taking one of the various means that can easily be embodied from the technical spirit of the present invention, the present invention is not limited to the following embodiment, Specific means can be implemented in a detailed design or later incrementally reinforced within the technical scope of the same category.

1 to 5 illustrate a typical communication state of a base station and a terminal, and FIG. 1 particularly illustrates a state in which a terminal station 1-2 is stably stopped in one cell 1 to maintain communication. It is shown.

In the conventional cell 1 as shown in FIG. 1, three sectors divided into A, B, and C are allocated as different channels with the base station 1-1 as a peak, respectively. The use of pseudo-noise codes is well known.

In Fig. 1 in which the user does not leave the sector C, the base station 1-1 and the terminal station 1-2 will naturally maintain a stable communication state each time confirmation communication is called.

FIG. 2 is a diagram illustrating a situation in which a terminal station in FIG. 1 is moved to an adjacent cell 2. The operation is as follows.

First, when the terminal station 1-2 reaches the interface between the cell 1 and the cell 2, the terminal station analyzes the communication parameters of the cell 1 and the cell 2 to determine the cell (2) than the cell (1). ), When the communication status of the terminal is good, the terminal station requests location registration from the base station 2-1 of the cell 2, and the cell 2 registers the location in the visitor location registration table (VLR). The location area identifier is updated, and the terminal station position at this time will be (2-2).

When the location is registered as described above, the cell 2 notifies the central centralized location registration table (HLR) 5 of the mobile station roaming number, which is the result of registration of the VLR. The base station 2-1 calls the terminal station 2-2 based on the VLR of the cell 2, and then the terminal station 2-2 is called. In this case, if the terminal station 2-2 is stopped, the base station 2-1 and the terminal station 2-2 will maintain a stable communication state for each confirmation communication as shown in FIG.

Here, if the terminal station 2-2 moves during the call, the cell 2 will additionally take a procedure of allocating a new call path, but this is not an area set as a problem in the present invention, and thus will be omitted. The technical content may be regarded as a general technical configuration.

3, 4, and 5 illustrate a sequence and a flow chart of the above procedure. When the power is initially turned on in the terminal 1-2, the terminal analyzes the communication parameters of the base station and selects a good channel. After capturing, the base station 1-1 requests location registration. Accordingly, the base station 1-1 registers the location of the terminal 1-2 in its VLR and generates a simultaneous mobile station roaming number. The registration is made known to the central HLR (101, 102, 103, 104, 105).

When the terminal 1-2 is stopped, the base station 1-1 and the terminal 1-2 continue to confirm communication based on the VLR registered thereafter (106), and if the terminal (2-2) If you enter the coverage area of another base station 2-1, the first operation is repeated again. (107, 102, 103, .....)

The process (106) in FIG. 4 is mainly depicted in more detail in terms of the base station system operation. In FIG. 5, the base station determines whether the terminal requests location registration (1061) or calls (1062). It always searches and takes appropriate countermeasures (1051, 1052), and if there is no such request, it performs periodic acknowledgment based on the VLR of 1051 (1063).

Here, the detailed processes (1061, 1062, and 1063) as shown in FIG. 5 may use separate channels or may perform all of them in one channel, but in principle, the conventional algorithm of the same algorithm may be used. In the following description, such a channel use means will not be distinguished from the description, and a description of the specific process of forming a call between the base station and the terminal station in FIG. 5 will be omitted for reasons other than the present invention.

The above-described process is a location registration and confirmation communication procedure of a conventional terminal, and even though there are some differences depending on the system, in principle, the same algorithms in the above categories will be described. The technical principle is described in detail as follows.

FIG. 6 is a sequence diagram illustrating that a confirmation communication process between a base station and a terminal station is different due to the present invention in a mobile communication network including a base station having a plurality of communication rights (cells) and a terminal station moving within the communication right. (sequence diagram), FIG. 7 shows a flow chart, and FIG. 8 is a diagram illustrating FIG. 7 implicitly in a layer diagram.

6 to 8, after all, the core of the present invention repeatedly executes three layers, namely, a stop status determination step, a link condition setting step, and a link execution step after location registration, in particular, whether the terminal detects a stopped state, It can be seen that the following dynamic setting provides a means for significantly reducing the number of confirmation communication.

7 and 8 will now be described in detail the confirmation communication process (①, ②, ③) of the present invention to be implemented after the initial initial position registration is made as follows.

A first step (206, LO) of determining whether the terminal is in a stationary state as a stop state determination function;

The detailed means of this step includes a parameter analysis means (communication parameter analysis) for determining, as a communication signal, a state in which a terminal is fixed at a place or a walking movement within a range of a short-range section, such as an interior of the same building. Function) and geodetic means (GPS positioning result analysis function) for determining whether the stationary state of the terminal, which is mainly within a certain range of the outdoors, is optionally or mixed according to the positioning result using the GPS (Global Positioning System).

The parameter analyzing means indirectly determines whether the terminal is in a stationary state according to the base station signal or the terminal station signal, and the identification signal (Pilot Carrier) of the base station or the bit error rate (BER) during communication has a predetermined effective range. It is determined that the terminal station is stationary when it is kept within, and that the terminal station is moving when the BER (Bit Error Rate) during communication is out of a predetermined effective range.

Here, the effective range means that the level or BER of the other party's signal has elapsed for at least one set time or more, and the measurement result is maintained within the set range, even if a plurality of base station signals arrive at the same place. If the level of the base station signal is maintained at an appropriate level, the terminal does not necessarily need to register location with another base station.

The geodetic means is means for judging that the mobile station is moving when it is out of a predetermined range, for example, 100m after the immediately preceding confirmation communication, for example, if it is stopped from the GPS receiver installed in the terminal station.

According to the parameter analysis means, even if the terminal is stopped in the same place, there is a possibility that it is sometimes misjudged that it is moving, such as when the signal is severely changed due to the traffic conditions such as a train or the like. At the interface between the cell and the cell 2, there are some disadvantages that it is difficult to completely match the characteristics of the network due to the possibility that the geodetic result and the signal intensity do not coincide. Therefore, the most preferable means is a method of combining the parameter analyzing means and the geodetic means. However, since it should be considered in terms of the cost increase by embedding the GPS receiver, the present invention includes both methods / means for making the individual applications or hybridizing them.

In this first step, as described in the second step below, the station status control result is notified to the counterpart so that the polling period called by the base station can be set variably or the terminal is not directly informed by the terminal without controlling the execution. You may.

In this step, the base station can recognize the stationary state of the terminal, when the terminal has been informed of the stationary state, the method of the terminal can recognize the stationary state by directly analyzing the signal parameters of the base station to determine or geodetic means Determined by

In addition, another method for recognizing the stationary state of the terminal in the base station, when the terminal does not respond to the call while the terminal registers the location in another cell or sector (sector) or the power OFF signal is not delivered The base station has a method of inferring that the terminal has entered the standby state.

Accordingly, the stationary state determination function or the stationary state determination means of the present invention means a means for alternatively or comprehensively applying at least one or more of the above means, wherein the stationary or mobile mode is selected by an artificial button operation in the terminal and the base station It also includes a means for detecting this, specifically, to be commanded only by the buttons respectively when entering and releasing the stop phase, or by button operation when entering the stop phase and automatically carried out by the analysis algorithm (program) when entering the moving phase. It is controlled to execute the confirmation communication dynamically by interlocking with the movement and stop of the terminal, including means for mixing it with the GPS positioning result analysis function or the communication parameter analysis function or configuring the reverse principle.

② The second step (207, L1), which is a link condition setting function that is linked to the first step, is configured to automatically change and set the communication link when the terminal is moved and stop the communication link when the terminal is stopped according to the result of the first step. ;

In this step, if the terminal is moving, the confirmation communication interval is shifted to a normal period (2071, 2072), and if it is not moving, that is, the standby function automatically sets or pauses the confirmation communication interval as a long function automatically. Means 2071 and 2073 are included. When the most desirable result is obtained through such variable link condition setting, power consumption of the terminal is drastically reduced to be comparable to that of the radio receiver, and accordingly, electromagnetic wave generation is naturally eliminated. This improves the traffic capacity as another terminal station can send and receive messages in the idle period.

If, when the base station confirms and communicates the terminal device by polling and the station performs the stationary state determination function, the stationary state determination result of the terminal may be included in the packet information and transmitted to the base station. The polling period is changed by comprehensively setting the link condition by managing whether the terminal is in a stopped state as a sub table.

If there is no means for notifying the base station of the terminal's standby state, the terminal automatically varies the communication cycle and the response unresponsive state (that is, the standby state) is analyzed by the base station immediately before the corresponding terminal is analyzed. This means may be rather desirable in that it is inferred that it has entered the standby state, and if the inference analysis algorithm is highly reliable, there is no traffic passing information to the other party.

In case of receiving the stop status from the base station, the normal confirmation communication can be paused or changed at very long intervals, and when there is a call event from the external network, the terminal can be called immediately based on the final VLR. However, even at this time, if the mobile station arbitrarily moves or the communication state becomes poor, the base station cannot make a call. Therefore, when the mobile station determines that the mobile station is busy, the mobile station returns to the original state by performing confirmation communication again. After that, the process of "① → ②" is implemented from the beginning.

Of course, in this step, when returning from the standby state, the process of returning to the original acknowledgment communication cycle (normal) may be omitted, and once the acknowledgment communication is performed, the apparatus may return to the original communication cycle. Includes means for choosing any of these means.

The specific confirmation communication normal function or confirmation communication short function in this process is a function that is set during the movement of the terminal, and the function according to the confirmation communication suspension or the confirmation communication pause function is a function that is set during the stopping of the terminal. It is automatically set according to the result (the confirmation communication normal function or confirmation communication short function includes a known technique).

In addition, the base station system in this process, if the GPS position (if any) that is periodically transmitted from the terminal does not change within a predetermined range, it is determined that the stationary state of the terminal or the user operates to recognize the stationary state arbitrarily. It also includes a means to set the communication period very long or change the operation state of the terminal to the saving mode.

Therefore, the link condition setting function or the link control means of the present invention includes a confirmation communication link changing means applied during moving and stopping as described above, and optionally includes means for notifying the other party of the change setting state. Can be.

A third step (208, L2) in which the base station and the terminal station execute the communication link on the basis of the condition set and changed in the second step as the link execution function linked to the second step;

In this step, specific communication is executed based on the function set in the second step, and the acknowledgment communication is sometimes managed by managing related tables and processes linked with the VLR even when the base station changes the polling period or pauses the communication. Means for implementing may also be included.

If the base station operates in a mutually competitive access method rather than polling, the base station detects a situation in which the terminal stops confirming communication as a result of the first and second steps, and allows the terminal to access the slot signal (Pilot). Also known as signal or free signal), such as changing the interval.

That is, in this step, the base station detects the stationary or moving state of the terminal and calls the terminal as a changed set communication period (polling, etc.) and the terminal stops or moves to the other party by calling the base station in its own stationary or mobile situation. Means for notifying the situation or renewing the location registration (competitive access, etc.) is included, and here also may include means for notifying the base station of the situation entered into the standby state when the terminal is stopped.

The main point in this process is dynamic control according to the movement and stop of the terminal, which automatically changes the period in which the base station calls the terminal, or sets the period in which the terminal station does not comply with the base station call. Means are included, wherein the means that the terminal does not comply with the call of the base station is only the amount of information corresponding to the polling or slot signal as a radio signal of the communication network in that there is no signal indicating the standby state between the base station and the terminal 1 It is characterized by a reduction of about 2.

In addition, this step may include means for transmitting a pilot signal to the base station at a predetermined period when the terminal is waiting, so that the base station can directly determine the stopping or moving situation in the first step.

Thus, the link execution function or link execution means of the present invention includes means for selecting or mixing at least one or more of the means for executing the communication link according to the result of the second step, wherein the base station signal is weak. It may of course also include means for configuring the link control, i.e., link execution to enter or release the economy mode, by utilizing the existing function of automatically entering the economy mode when it reverses.

The foregoing descriptions of the embodiments of the present invention describe the method, function, and configuration means in the cellular system for easy understanding by those skilled in the art, but this is the system configuration and computer program configuration means in the base station computer or the terminal station microprocessor. Application, i.e., the stationary state determining means is obtained from a parameter analyzing means or a GPS positioning means interlocked with a receiver output terminal of a terminal station system, and the link control means is a hardware or an input condition of an encoder or a transmission drive circuit comprising a system or a terminal.

Among the terms of the present invention, the term "varies the communication link period for (confirmation) communication to be very long or paused" is a conventional confirmation communication period (here, published on October 29, 1999) Publications disclosed in Japanese Patent Application Laid-Open Nos. 11-298945 and published on July 18, 2002, which include a known technology disclosed in Korean Patent Application Laid-Open No. 2002-0060589) to effectively prevent electromagnetic interference within a period of "maximum infinity." This means that the confirmation communication period is set dynamically (that is, dynamically) by following whether the terminal is stopped ↔ moving or not. In the link execution, when the base station controls the polling method, the terminal responds to the polling of the base station. The term encompassing the term includes a means for changing the response period so as not to be implemented or a means for not connecting to the access permission signal corresponding to the slot signal of the base station. It is defined as "subject to the stop."

That is, in the present invention, the "communication link automatic control method" or the "wireless communication system terminal" is a term that includes a technical principle that the terminal is particularly active in the configuration in which the base station and the terminal station is interlocked.

In the term of the present invention, the term "combined into effective means" means various means in which software or hardware, which is each component, is combined so that interworking is established by natural law in order to configure the communication link automatic control method or wireless communication system terminal. Thus, the control circuit means depicting this includes structural means configured to operate in conjunction with a program using firmware or software, as well as means for connecting the circuit elements by wires to perform their functions. .

In the present invention, the automatic control of the communication link means a means of automatically changing the period of the radio link between the terminal and the base station to stop at a normal period, i.e., eliminating electromagnetic interference, regardless of whether the HLR or VLR is updated. Also includes a means of limiting a connection (link) in a simple wireless communication network to dynamically (ie, dynamically change) following tracking of a terminal to a movement of a mobile station.
In the claims of the present invention, the term "quality analysis of a received signal" is an abbreviation for parameter analysis that is analyzed as a signal level and / or bit error rate as described above.

According to the present invention, an unnecessary communication link between a base station and a terminal station is suppressed, and in particular, electromagnetic interference is eliminated, and consequently, battery power consumption and communication network traffic are greatly reduced, and the mobile terminal remains intact. In addition, there is another side effect of suppressing space propagation noise and the inconvenience caused by frequent charging.

In particular, in the use of a mobile phone, almost all users can see that the effect of the present invention is a substantial remarkable effect in view of the fact that most of the time of the day is walking within a certain range such as a stop or an office. Keep the terminal away from the human body when using the vehicle (use hands free), and use the earphones to keep away from the human body during the call, and operate the terminal only like a normal portable radio receiver during normal mobile use, so that the electromagnetic interference is completely perfect in any situation. As a result, the present invention provides a new information technology that satisfies the needs of biotechnology and environment technology.
The effects of the present invention are disclosed in the prior art (Japanese Patent Laid-Open Publication No. 11-298945 and Japanese Patent Laid-Open Publication No. 2002-0060589 published on October 29, 1999). In contrast to,
First, 'JP-A No. 11-298945' is intended to reduce battery consumption of a terminal, and determines a moving speed between each base station of a terminal based on longitude / latitude information included in signals received from several base stations and corresponding positions. Since the registration period is variable, 'JP-A No. 11-298945' cannot determine and control the stationary state in the same sector of the same base station as one base station, and in this case, there is no effect of preventing electromagnetic interference. By judging and controlling the stationary state in the same sector of the base station, there is an effect of reliably eliminating electromagnetic interference even in the single base station.
In addition, even in the range of improving the conventional technology, 'JP-A No. 11-298945' informs the base station of the change of the position of the terminal, and the base station calculates the movement speed as the position movement per unit company and confirms that it corresponds to the movement speed. In the present invention, a new confirmation communication cycle variable technology can be implemented only when the base station and the terminal are provided with a change in the control technology because the base station and the terminal are provided with an integrated configuration. Since this is a distributed asynchronous method that unilaterally changes (varies) the acknowledgment communication period, there is a remarkable difference in effect in that a new acknowledgment communication cycle variable technology can be implemented by only changing the configuration of the terminal.
In addition, 'JP-A No. 11-298945' indicates that a plurality of base station signals received at a location where a terminal is located is increased or decreased. If unstable, the terminal may receive a latitude / longitude of another base station instantaneously even if it is fixed, and malfunction as if the terminal is moved. The drawback is that the probability of malfunction is further increased in the light of the fact that the base station signals are increasingly overlapping in the same place with respect to the trend of differentiation of base stations into micro cells, pico cells, and nano cells in a densely populated metropolis. Obviously, the present invention detects a signal level from a single source and judges a stable stationary state through a separate GPS measurement position, so there is no room for such a malfunction, and the signal quality of a single source can be analyzed. Even when a plurality of base station signals are received, the signal of the base station In that stable to literally stop a check that does not communicate it is very low, with no significant effect on the stability of the side effects.
In the end, this invention is focused on traffic dispersion and power saving by detecting the boundary of "high speed ↔ low speed" in which "Hok 11-298945" is moving and changing the confirmation communication period within a certain range. Since it is a heavy invention to stop the confirmation communication itself to the maximum infinity by detecting the boundary of ↔ move "and stopping the confirmation communication during the stop, it is understood that the unique electromagnetic interference is solved through its configuration and operation.
On the other hand, 'Special 2002-0060589' is a base station through a technology or a terminal (connection) of the base station to determine the location registration period based on the reception frequency information of the mobile station for the purpose of improving the traffic processing capacity of the communication network In order to know whether the terminal is indirectly moved according to the technology of determining whether the terminal is indirectly, an appropriate level of registration period (normal communication link cycle and short communication link cycle) is necessary. In his own judgment, the effect of suspending the communication link for preventing electromagnetic interference cannot be expected, and 'Specific 2002-0060589' refers to a means for prolonging the location registration period very much according to the mobile status information of the mobile station. However, this is a mobile station information that is registered in advance in a fixed vending machine. Registers in advance and notifies the base station to fix the period at the base station.) Therefore, the terminal directly determines the stop / move, and accordingly, the terminal automatically suspends or returns the confirmation communication according to the dynamic link control. Since the present invention is fundamentally different from the present invention which fundamentally eliminates the obstacles, the technical configuration is different from the present invention, and in the end, the terminal automatically stops or restores the confirmation communication itself by automatically following the mobility of the terminal. Compared to technology, there is a dynamic effect excellence.
