Description

METHOD AND TRANSFER CONTROL DEVICE USING CONFUSED LOGIC Field of the invention In general, the present invention is concerned with cellular telephone networks and more particularly with the use of confusing logic to control transfers in such systems.

Description of the Related Art A cellular telephone network is a system that provides radio communication to and from mobile telephones in a large geographic area. Cellular networks generally consist of a plurality of attached geographical regions, subdivided into cells. A portion of a cellular telephone network of the prior art is illustrated in Figure 1. Each geographic region, commonly referred to as a cell 10, has a base transceiver station 12, which can communicate via radio waves to and from a telephone mobile phone, which is not shown in figure 1. Mobile phones are frequently used inside a car 22. Each base transceiver station is also connected to a controller 16 of the base station by means of a group of terrestrial telephone lines, commonly called as a trunk 14. Each base station controller 16 is normally connected to several REF: 29232 base transceiver stations 12, each base transceiver station 12 serves a different cell 10. Each base station controller 16 is connected by a terrestrial trunk 18 to a mobile switching center 20. A mobile switching center 20 is normally connected to several base station controllers 16. Finally, a cellular network typically contains several mobile switching centers 20, each mobile switching center 20 is normally connected to. several other mobile switching centers 20 and is connected to several base station controllers 16 and each base station controller 16 is normally connected to several base transceiver stations 12. During a cellular call, a mobile telephone communicates with station 12 of the base transceiver by using a particular frequency of radio waves. That frequency is predetermined by the base station controller 16 for cell 10 in which the mobile telephone is located.

Frequently, mobile phones are used in automobiles 22 and as the mobile telephone moves away from the base transceiver station 12 handling the call, normally the mobile telephone approaches one or more of the base station transceivers 12 and the The quality of the transmission between the mobile telephone and the base transceiver station 12 handling the call tends to deteriorate. If the quality of the transmission decreases significantly, the call must be "transferred" to a different transceiver station 12, such that the call can proceed between the mobile telephone and the base transceiver station to which the call is transferred. . Although the mobile phone is initially tuned to a pre-assigned frequency for the call, the mobile phone also monitors other frequencies during a call. The frequencies that are monitored can belong to different base transceiver stations 12 to the base transceiver station 12 that handles the call. Periodically, the mobile telephone transmits to the base transceiver station 12 that handles the call, measurements related to the quality of the signal for the frequencies it is monitoring that includes the frequency that is used for the forward mobile call. The two directions in which the mobile telephone and a base transceiver station communicate with each other via radio waves are referred to as a downlink and an uplink. The downlink refers to the transmissions of the station 12 of the base transceiver to the mobile and the uplink refers to the transmissions of the mobile telephone to the base transceiver station 12.

The mobile phone measures the intensity of the downlink signal, the quality of the downlink signal and the power of the battery that is used by the mobile telephone to transmit radio waves to the base transceiver station 12. During a mobile call, these measurements are transmitted to the base transceiver station 12, which in turn sends them to the controller 16 of the base station. The base transceiver station 12 measures the intensity of the uplink signal, the quality of the uplink signal and the distance between the mobile telephone 30 and the base transceiver station 12. Then, the base transceiver station 12 relays these measurements to the base station controller 16 which determines whether to transfer the call based on the measurements taken by the mobile telephone 30, the measurements taken by the transceiver station 12, the call duration and the speed at which transfers are made for a particular call. The duration of the call and the transfer rate are maintained by the controller 16 of the base station. A controller 16 of the base station and the base transceiver stations 12 which are connected to the controller 16 of the base station are referred to as a system 24 of the base station. If a call is transferred from a base transceiver station 12 to another base transceiver station 12 in the same base station system 24, the transfer is referred to as an intra-base station system transfer. If a call is transferred to a base transceiver base station 12 in a different base station system 24 that is connected to the same mobile switching center 20 as the first base station controller 12, then the transfer is referred to as an intra-pass transfer. mobile switching center. If a call is transferred to a base transceiver station 12 in a different base station system 24 that is connected to a mobile switching center 20 different from the first mobile switching center 20 of the base station system 24, then the transfer is referred to as an inter-mobile transfer center transfer. Excessive transfers are undesirable. When a transfer is to be carried out, the telephone system resources necessary for the call must be reserved in another base transceiver station 12, which may be contained within a different base station system 24 and which could be connected to another mobile switching center 20. Inter-mobile transfer center transfers require the establishment of voice paths in a trunk between the two mobile switching centers and in a trunk 18 between the new mobile switching center 20 and the new base station controller 16. of these voice trajectories requires extensive signaling between the mobile switching centers 20 and between the controllers 16 of the base station and the mobile switching centers 20. The boundaries of the adjacent cells 10 are usually not well defined. a mobile telephone, for example, in a car 22, approaches the boundaries between geographically adjacent cells, transfer control mechanisms using clear or conventional clear logic often cause unnecessary transfers.The techniques for determining when to carry out transfers are known in the art and make transfer decisions in based on the distance between the mobile telephone 30 and the base transceiver station 12 handling the call, the quality of the uplink and downlink signal (collectively referred to as "quality"), the uplink signal levels and downlink (collectively referred to as "level") in decibels, the energy or power that is used to transmit radio waves in the uplink and the downlink (collectively referred to as "power") and the number of calls that is processed by the base transceiver station. The existing mechanisms to control transfers in cellular telephone networks use a clear or clear logic as opposed to a confused logic. The use of a clear or clear logic in the determination of whether or not a transfer is carried out suffers from the disadvantage of causing very sharp shots without any way to take into account, inaccurate data related to the quality of the uplink and downlink radio transmissions. In addition, the transfer is a very complex mechanism. Frequently, transfers are triggered by little-known causes. Transfers can also cause cellular calls to be interrupted. In certain situations, instead of simply deciding whether or not to transfer a call, it is desirable to adjust the power that is used to transmit the uplink or the downlink or both, in order to improve the quality of the received signal. Clear or clear logic is based on set theory where an element belongs to a set or not, for example, { 1, 2, 3, -1, -2, -3.}. of the so-called integers { 1.2, 1.3, 1.5.} belong to the set of real numbers, but not to the set of integers, for example, the color of a ball could be in the set. red, blue, ver.}.) However, when the ball is somewhat red, that concept can not be quantified by discrete mathematical set theory.The confused logic theory or confused set theory solves this problem by allowing the elements of a set have certain degrees of membership that and quantify the criteria of confusing logic such as not very red, somewhat red, quite red, very red, etc. The confusing set theory was first proposed by L.A. Zadeh in the 1960s. Since then, it has been used in numerous applications such as washing machines, cameras, artificial intelligence, linguistics, economics, filters, database recovery systems. Although non-linear systems can be very complicated to model when using mathematical bases in traditional set theory, confusing logic provides a simplified procedure for modeling such systems. It is therefore an object of the present invention to use confusing logic to determine whether a transfer should be carried out or not and whether the radio transmission power should be increased or decreased in order to control more reliably when transfers are carried out. To reduce, by this, the system resources required to process a particular volume of calls, improve the quality of the signal of the calls in the network and reduce the number of interrupted calls.

BRIEF DESCRIPTION OF THE INVENTION The present invention uses confusing logic to determine: (1) whether or not a cellular telephone call is transferred from a base transceiver station to another base transceiver station; and (2) if the radio transmission power is increased or decreased. The parameters related to the quality of the uplink and downlink radio transmissions, the duration of the call and the speed at which the call is transferred are measured. The membership functions of the confused set theory are applied to these measurements to turn them into confusing variables based on certain predetermined criteria. Then, the confused variables are introduced to a machine (or program) of inference. The inference machine makes transfer decisions by applying a predetermined set of rules of input for the inference machine. For example, if the measurements related to the quality of the radio transmissions indicate that a transfer should be carried out, but based on the length of the average call, the call is almost finished, then a transfer is not carried out. The present invention reduces the number of transfers carried out when a mobile telephone is on both sides of the border between adjacent cells by minimizing the number of transfers carried out when more transfers are carried out than the guaranteed ones based on the measurements related to the quality of uplink and downlink radio transmissions. The present invention also uses confusing logic to adjust the quality of energy used by the base transceiver station and the mobile telephone to transmit radio waves in the uplink and the downlink respectively, based on certain predetermined criteria. These as well as other new objects, advantages, details, embodiments, and features of the present invention will be apparent to those skilled in the art from the following detailed description of the preferred embodiment of the invention, the appended claims and the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS In the following text and in the drawings, in which like reference numerals denote similar elements in all the drawings, the present invention is explained with reference to illustrative embodiments in which: Figure 1 is a schematic illustration of part of a wireless telephone network of the prior art. Figure 2 is a block diagram illustration of a mobile telephone, base transceiver station, base station controller and mobile switching center.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT For a better understanding of the present invention, reference should be had to the following detailed description taken in conjunction with the appended claims and the accompanying drawings. Figure 2 is a block diagram illustrating a mobile telephone 30; a base transceiver station 12; a base station controller 16, having a call processing calculator 32 and a confusing logic controller 66 containing a "fuzzifier" 34, an inference machine 36 and a "defuzzifier" 38; and a mobile switching center 20. The controller 16 of the base station is drawn with a dashed line to indicate that it contains other components that are not shown in Figure 2.

The previously discussed measurements made by the mobile telephone 30 and the station 12 of the base transceiver are input to the "fuzzifier" 34, which is part of a confusing logic controller 66 and contains one or more standard membership functions, such as triangular, trapezoidal or square, which are used to confuse inputs 40 and 48 of the confounder, based on certain predetermined criteria. Such membership functions are well known in the art and are explained in Fuzzy Set Theory Foundations and Applications, George J. Klir, Ute H. St. Clair, Bo Yuan (Prentice Hall 1997). A first set of inputs 40 of the confounder is coupled to the output 42 of the station 12 of the base transceiver. Each "fuzzifier" entry in the first set 40 normally corresponds to a previously known parameter used to make transfer decisions, which include, in descending order of importance: distance, quality (for uplink 144 and the downlink 46), signal level (for uplink 44 and downlink 46) and power (for uplink 44 and downlink 46). Thus, the first set of 40 inputs of the confounder contains seven inputs, i.e., the distance, uplink quality, downlink quality, uplink signal level, downlink signal level, link signal strength ascending and downlink signal strength. These previously known parameters are collected by mobile telephone 30 and station 12 of transceiver 12. Although the preferred embodiment uses all of these previously known parameters, it will be obvious to those skilled in the art that any permutation or combination of previously known parameters can be used. without deviating from the scope of the present invention. A second set of inputs 48 of the confounder are coupled to the output 50 of the call processing calculator 32. The second set of inputs 48 of the confounder will normally comprise four inputs, in which the instantaneous values for the rate of transfer and duration of the call are included as well as average values maintained heuristically for the transfer rate and duration of the call. Although the preferred embodiment uses all four of these parameters related to the transfer and duration of the call, it will be obvious to those skilled in the art that any permutation or combination of these four parameters can be used without departing from the scope of the present invention.

Each output 52 of the confounder is a confusing variable generated based on one or more of the inputs 40 and 48 of the confounder. Each output 52 of the confounder is generated by applying a standard membership function to the corresponding input or inputs 40 or 48 of the confounder. The distance becomes confused in values of: very narrow, narrow, average, far or far away. The quality of the uplink and downlink signal each become confused in possible values of: very poor, deficient, average, good and very good. The transfer rate, the uplink signal level, the downlink signal level, the uplink signal strength and the downlink signal strength each become confused in possible values of: very low, low, average , high and very high. The duration of the call becomes confused in possible values of: very short, short, average, long and very long. Although each confused variable in the preferred embodiment has five values, it will be obvious to those skilled in the art that confusing variables having a diversity of possible values other than five can also be used without departing from the scope of the present invention. In the preferred embodiment, one of the outputs 52 of the confounder corresponds to the transfer speed and the outputs 52 of the confounder correspond to the duration of the call. These two outputs 52 of the confounder are generated in relation to averages calculated heuristically of transfer speed and duration of the call. In other words, the call processing calculator 32 maintains a running average value for transfer rate and an average operation value for the call duration. The instantaneous and average values of the transfer rate and call duration are represented in Figure 2 as the output 50 of the call processing calculator 32 and as inputs 48 to the confounder 34. Although the preferred embodiment includes the confounder 34 within the controller 66 of confusing logic within the base station controller 16, it will be obvious to those of ordinary skill in the art, that the generation of the inputs 54 confused to the inference machine 36 and that it receives those inputs 54 in the machine 36 of Inference does not deviate from the scope of the present invention. The nine outputs 52 of the confuser represent several system conditions, which have been previously discussed, ie, transfer speed, quality (for uplink and downlink), distance, level (for downlink and downlink), call duration and power (for uplink and downlink). The outputs 52 of the cxKifusor ("fuzzifier") are coupled to the inputs 54 of the machine 36 of inference. The inference machine 36 contains a set of rules that are based on predetermined criteria that indicate when the transfers are and are not desirable, as well as when changes in the quality of the uplink and downlink transmission power are desirable. The inference machine 36 applies this predefined set of rules to the inputs 54 of the inference machine. If the values of the inputs of the inference machine 54 satisfy any of the rules contained in the inference machine, then the inference machine generates a confused variable in the output 56 of the inference machine. In the preferred mode, the confusing variable generated by the inference machine, the confusing transfer action, has possible values of: desirable transfer, undesirable transfer, slight increase in power, moderate power increase, increase at maximum power, slight decrease in power, the power and moderate decrease in power. In the preferred embodiment, the inference engine includes the following rules: Table 1, the conditions summarized in the crue columns containing a condition must all be satisfied in order for the conditions of a rule to be satisfied. In other words, for a particular rule, the conditions specified in each column are combined in Y, not combined in OR logically with the conditions specified in other columns. For example, rule 1 is satisfied when the transfer speed is average, the quality is good and the distance is far. In addition, the columns named quality, level and power each represent the quality, level and power respectively, for the uplink 44 or the downlink 46. The rules 1-10, dealing with the question whether it is desirable or not a transfer, will be activated if the value specified in any of those three columns, corresponds either to the uplink 44 or the downlink 46. For example, the requirements of rule 1 will be satisfied if the transfer speed is average, the distance is far away and either: (1) the quality of the uplink signal is good or (2) the quality of the downlink signal is good. Rules 11-15, which deal with the quality by which the transmission power must be adjusted, are applied separately to the uplink power and the downlink power. Thus, the output 56 of the inference machine could indicate a change for either the uplink transmission power or the downlink transmission power or both, individually. It will be obvious to those of ordinary skill in the art that any permutation or combination of values could be used to formulate additional rules for determining new uplink and / or downlink transmission power values. It will also be obvious to those of ordinary skill in the art that table 1 contains a very limited number of rules and that many rules could be added to table 1 without departing from the scope of the present invention. One of the benefits provided by the present invention is that it can prevent a transfer from occurring in a situation where, statistically, the call is almost completed, as shown in rule number 4 in table 1. If the duration of the a call is, at least, relatively close to the average call duration and the other factors considered to make a transfer decision indicate that a transfer must be carried out, rule 4 in table 1 is activated and a transfer. Another benefit provided by the present invention with respect to the prior art is that the present invention uses the rate at which transfers occur in conjunction with other factors to prevent unnecessary transfers that interrupt service. For example, the transfer speed could be high while the parameters of quality, level and distance are not deficient enough to guarantee such a high transfer rate. Such a situation occurs when the mobile telephone 30 is on both sides of a path where the base transceiver stations 12 are at transfer threshold levels and the thresholds are very frequently tested. Under these circumstances in the prior art systems, transfers can be presented at an abnormally high speed, which wastes system resources and could cause interrupted calls. In addition, the number of transfers carried out for a call is provided to the billing schedule elements in many cellular telephone networks and if an excessive transfer number is presented, a cellular telephone billing of the customer can be unnecessarily increased. Rule 10 in Table 1 minimizes the likelihood of transfers occurring under these conditions, to reduce by this the undesirable effects of an excessive number of transfers.

Although the previously known parameter used to make transfer decisions indicating the number of calls that are handled by the base transceiver station 12 was not incorporated in the preferred embodiment, it will be obvious to a person having ordinary skill in the art, that rules could be formulated to cause transfers to occur on a basis, at least in part, to the number of calls that are handled by the base transceiver station 12 that handles the mobile call without deviating from the scope of the present invention. Such rules could be useful for transferring calls from a base transceiver station 12 that handles a relatively high number of calls to a base transceiver station 12 that handles fewer calls. The present invention also uses confusing logic to control the transmission power used by the mobile telephone 30 and the base transceiver station 12 in order to reduce the number of transfers required to process a given volume of calls, as shown in the rules 11 to 15. If the inference machine (or program) 54 does not emit a value related to the power, then the amount of transmission power used by the mobile telephone 30 and the base transceiver station 12 will remain unchanged.

The output 56 of the inference machine is coupled to the input 58 of the de-confuser ("defuzzif ier"). Depending on the value entered ("?" &"Ez ± Eier") 38, demixing ("e & pfier") 38 emits a clear or clear logic value that indicates whether or not it should be carried out a transfer or the "defuzzifier" 38 emits a new power value or values for use by the mobile telephone 30 or the transceiver station 12 or both. As mentioned previously, the change in the uplink transmission power and the change in the uplink power are controlled independently. For the purpose of brevity, the following discussion of how the new power values are generated by the de-confuser 38 is limited to the modified uplink power values but is also applied to the downlink power values. In the preferred embodiment, the minimum transmission power Pm?, -., Used by the mobile telephone 30 is 20% of the maximum power, Pax, used by the mobile telephone 30. The output values of the inference machine indicate power changes, that is, slightly-increased power, moderately increased power, slightly decreased power, moderately diminished power, and increased power to the maximum, cause the demister to emit a new power value, Pnu »vo, for the mobile phone 30 in relationship with the current power of the mobile phone, P, as follows: slightly increased power: PnUevo = P + 0.4 (Pmax - P); moderately increased power: Pr! Uyo = P + 0.8 (P "ax -P)} slightly decreased power: PP.u »yo = - 0.4 (P - P" in); moderately diminished power: Pr, uev = P - 0.8 (P - P - n -. * -,); The output 60 of the demister is coupled to the input 68 of the call processing calculator. In another embodiment of the present invention, the inference machine 36 emits clear logical values that indicate whether a transfer should be carried out or whether a new power value is desirable, the inference machine 36 emits the new power value for the mobile telephone 30 and there is no de-confusor 38. If the entry 68 of the call processing calculator indicates that a transfer must be carried out and the base transceiver station 12 to which the call will be transferred is located in a system 24 of different base station, then the call processing calculator 32 notifies the mobile switching center 20, the output 70 of the call processing calculator, which is coupled to the input 64 of the mobile switching center. If the input 68 of the call processing calculator indicates a new power value for the mobile telephone 30 or for the station 12 of the base transceiver or for both, then the call processing calculator 32 notifies the base transceiver station 12 of the new power value or power values, via the output 72 of the call processing calculator, which is coupled to the input 62 of the base transceiver . If a new power value is generated by the mobile telephone 30, then the station 12 of the base transceiver transmits that new power value to the mobile telephone 30 via the downlink 46. Although the preferred embodiment is discussed in the context of cellular telephone networks , it will be obvious to those skilled in the art, that the present invention is applied to personal communication systems operating in the range of 900 MHZ, satellite communication systems, aircraft tracking systems and any other wireless communication system that carry out transfers or transfers of analogous messages to transfers as described above. It will be obvious to those skilled in the art that the present invention can be implemented by using a programmable confusing logic controller, completely in programming elements or by using microprocessors, microcontrollers, digital signal processors and the like. It is noted that, with regard to this date, the best method known to the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention. Having described the invention as above, property is claimed as contained in the following:
