4 is a flowchart illustrating an embodiment of an initialization method of a mobile communication system for transmitting performance measurement information from a mobile telephone to a mobile communication system in accordance with the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same components have the same reference numerals as much as possible even if they are displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

An embodiment of the present invention stores at least the location information and time measurement of the mobile phone, and if the failure of access attempt, call disconnection, low signal strength pilot signal measurement or total loss of CDMA signal occurs, A mobile telephone is provided that stores a record of performance data indicative of a pilot PN offset. The stored performance data may be transmitted to a database of the mobile communication system for the mobile phone to analyze by the cellular service provider. The cellular service provider may use the performance data collected from the mobile phones of various users to assist in providing an improvement in the quality of service provided to the users. That is, the performance data can statistically provide the locations of areas that are poor or receive problems in the service area. The performance data may also represent dense locations based on one day or any time. In particular, the performance data may be used to coordinate cellular services based on periodic signal interference or non-interference by summer foliage and attenuation of the foliage when the foliage disappears in winter. The performance data can be used to establish areas within a service area that have high "pilot contamination" (too many pilot signals) or inappropriate cell handoff boundaries.

It is to be understood that the term "cellular" in the present invention is not necessarily limited to 800 MHz mobile communication but includes cellular, PCS TDMA, CDMA, GSM or other mobile or wireless communication systems.

After the collected performance data has been operationally recorded on various mobile phones, the mobile communication system provider can geographically map and map areas with service problems.

Once the various service problem areas are represented geographically, the service provider can better know which service areas need upgrade or service coordination. GPS circuitry within the phone can be used to locate or track a user in a "911" emergency. That is, the user can use the GPS circuitry of the mobile phone to assist emergency teams (firefighters, police stations, emblems) to locate the user in case of an emergency.

1 illustrates a first embodiment of a mobile communication system according to an embodiment of the present invention. With reference to FIG. 1, the mobile network system may be any other cellular telephone system including a CDMA, TDMA AMPS or satellite network based largely on a communication system. The mobile telephone 10 includes a general mobile telephone circuit 14 suitable for the cellular type and operates within the mobile or wireless telephone network.

In other words, the digital circuits such as the operation circuit, the RF preprocessing circuit, and the antenna 16 common to the mobile telephone are included in the general telephone circuit 14. The position measuring circuit 18 enables the mobile telephone 10 to always determine the geographical position of the mobile telephone 10 while the mobile telephone 10 is on. The GPS or other location tracking circuit 18 may be used in the event of a "911" emergency call that dispatches firefighters, police or paramedics to the location of the mobile phone.

The call state recorder 20 is configured inside the mobile telephone 10 or is accompanied by a mobile telephone circuit 14. The call state recorder 20 may operate with circuitry and / or software for storing statistics on the firmware of the mobile phone and the services provided by the mobile communication system 12 in the call state recorder 20.

When the triggering event occurs, the position measuring circuit 18 provides the geographical position information of the mobile telephone 10 to the mobile telephone system stored in the call state recording unit 20.

The performance data stored in the call state recorder 20 is generally related to the quality of the signals, mobile phones out of service, call disconnected or non-outgoing mobile phones. These can trigger a triggering event.

In FIG. 1, the mobile telephone 10 communicates with a base station transceiver system (BTS) 22 in a general wireless manner. The BTS 22 is connected to a Base Station Controller (BSC) 24 and to a Mobile Switching Center (MSC) 26 in a general manner.

The MSC 26 is a computer of which means for gathering performance data from multiple mobile phones

Or a service provider (Servicer = Processor 28). And MSC 26 is to provide location information and substantial test plots from the performance data with respect to specific cover areas.

The cover areas may be part of a city or a small city, a town, a municipality, or the like. The processor 28 provides a mobile communication system operator with the geographical location of the mobile phone 10 in the service areas.

The mobile telephone 10 transmits not only voice data but also various types of data.

2 is a flowchart illustrating an embodiment of an operation of a mobile phone for collecting system performance data according to an embodiment of the present invention.

Referring to FIG. 2 above, the flowchart shows a preferred “Triggers Event” that initiates the collection of statistical data for storage in the call state recorder 20.

Each record stored in the call state recorder 20 includes various forms of information about each triggering event. For example, the information that may be stored when a trigger event occurs may be the triggering event that causes the collection of data and statistics about the mobile phone location information or surrounding cell site pilot signal strength.

If the network system is a CDMA system, the call state recording unit 20 is configured as shown in the table below.

Index-Points (1-N) trigger Code-Indicates reason for call status entry Primary Pilot PW (0-512)-Cell Identification Other PNS in active area date time Latitude sign N or S (0 or 1) Latitude (degrees) 0-90 Latitude (min) 0-59 Latitude (seconds) 0-59.999 Longitude symbol E or W (0 or 1) Longitude (degrees) 0-180 Longitude (min) 0-59 Longitude (seconds) 0-59.999 Neighbor Cell Identification

In FIG. 2, the mobile phone 10 collects the performance data, and stores the performance data measured by the additional measurement process of the mobile telephone circuit 14 in the call state recording unit 20.

The first triggering event 114 is for determining whether a "service" indicating whether a subscription service or a service provider's mobile network system service is available for the mobile phone.

If not, the triggering event occurs because the user cannot establish a call with the assigned service provider.

The second triggering event will occur when the previous user attempts to make a call. However, the call attempt is not successful.

That is, if the user attempts to call someone with mobile phone 10 and receives a "Reorder Signal" indicating that the mobile network system can then store the call, this is an extra channel to provide for another call. This may be due to the nearest cells in full capacity mode.

The third triggering event may be a call that is interrupted or truncated depending on the extent to which mobile phone 10 transmits an active call and some calls are suddenly dropped or discontinued.

Other triggering events include too weak communication signals, too strong communication signals, too high frame or digital signal errors, pilot contamination, or criteria that degrade the voice or quality of service provided to a mobile phone user.

In step 100 of FIG. 2, the mobile phone 10 is turned on. In operation 110, the mobile telephone 10 measures whether a service provided by a mobile network service provider is available. If the service is not available, the mobile phone 10 is measured through a position measuring circuit (GPS) to find a serviceable target in step 112.

When the service is provided, the mobile phone 10 continuously receives the location information signal to identify the location information that has not been serviced and store the performance data in the call state recorder 20. For example, when a user is provided when the user comes out with the mobile phone 10 in a non-serviced building or tunnel, the user stores the location information in the call state recorder 20. In step 114, the call state recorder 20 stores the unserviceable failure code upon receiving the location information signal. The performance data stored in the call state recorder 20 includes necessary statistical data such as pilot signal strength, PN, date, time, location information, triggering event code and index pointer, cell identification information, and neighbor cell site identifier. .

In the present invention, the location information and the triggering event will be described by limiting the code. Moreover, additional statistical data is precisely and easily enabled for statistical analysis and pilots of mobile networks. If the service is available in step 110 and the user attempts to make a call in step 116, in step 118, the mobile telephone 10 measures whether the call is established.

In other words, if the call is not formed, if the mobile telephone 10 cannot access the mobile network system to form the call, step 120 is performed. When the GPS signal is detected in step 120, the call attempt failure is stored in the call state recording unit 20 in step 122. That is, a call state record of the call attempt failure is made.

If the call attempt succeeds in step 118, the flow proceeds to step 124 to identify a triggering event for call disconnection. If the call is cut, go to step 126. If a location information (GPS) signal is detected at step 126, call cutting is stored in the call state recording unit 20 at step 128. This continues until the user of the mobile telephone 10 completes the call in step 130. As described above, other triggering events include too strong or weak signals affecting neighboring cells, too frequent frame or digital sync signal loss, noise signals, or cell site handoff failures.

3 is a flowchart illustrating an embodiment of an initialization method of a mobile telephone for providing a performance measurement to a mobile communication system according to the present invention. Referring to FIG. 3, a plurality of mobile telephones stored in the call state recording unit 20 are described. Call state records for these 10 should be provided at processor 28 for use as statistics on the service area providing the service.

In step 200 the mobile phone 10 is turned on. The mobile telephone 10 measures whether the mobile telephone 10 is in a service area for providing a mobile service in step 202. When in the service area, the mobile phone 10 checks for any failed records recorded in the call state recorder 20 in step 204. If the performance data does not have a call state record, nothing is needed.

On the other hand, if there is performance data stored in the call state record, the algorithm for starting call record correction is waited for a predetermined time in step 206. The waiting time is performed because many mobile phone users "turn on" their phones to make calls. Thus, the algorithm will not prevent the user from being able to form the desired call. After step 206, it is determined in step 208 whether the mobile phone is in a call state for the user. If the phone is in a call state, the another waiting period continues at step 210. Repeat the following process. If the mobile phone 10 is not in a call state in step 208, the mobile phone 10 will diverge to the mobile communication system 12 and request a download permission to its call state part 20 in step 212.

If the acceptance for the mobile network is not made, the method returns to step 204 and repeats the subsequent process.

Denial of acceptance of mobile phone 10 for download of mobile communication system 12 is currently related to rush hour, lunch break or call capacity that must be used for the user's calls, where performance data cannot be downloaded from call state log 20. The triggering event is operated with "peak".

Acceptance for transmitting / downloading performance data in steps 212 and 214 may be performed in a variety of ways.

One technique is to send a message requesting that the mobile phone 10 is ready to accept performance data from the mobile phone 10 with the BTS 22 identification code. The BTS 22 will therefore send a response to the mobile phone 10 as to whether it is ready to receive the performance data.

Another technique would be for the BTS 22 to send a paging channel code to mobile phones 10 communicating with another BTS. The mobile phone 10 checks the bits present in the paging channel to determine whether a predetermined bit is set indicating that the BTS 22 can download / transmit performance data.

When receiving the transmission of the performance data of the bit or bits in step 214 or when the BTS 22 informs the mobile phone 10 of the download / transmission of the performance data, the mobile phone 10 transmits the performance data in step 216. To BTS 22 of system 12.

After the performance data is transmitted, the mobile phone 10 clears the call state recorder 20 in step 218.

In essence, the mobile phone 10 that has initiated the transmission of call state recorded performance data of the mobile phone 10 indicates whether it operates in the service area, and measures whether the BTS 22 can receive the performance data. May transmit / download the recorded performance data to the BTS 22. The mobile phone 10 deletes the previously stored call state record.

It should be noted that there are techniques for data call formation or data transmission on mobile phones. Preferred embodiments of the invention will have the advantage of any standard being moved. There are currently some original data call standards. For example, the standards include IS-95A, IS-95B, or CDMA 2000 including 1 × RTT and 3 × RTT.

4 is a flowchart illustrating an embodiment of an initialization method of a mobile communication system for transmitting performance measurement information from a mobile phone to a mobile communication system according to the present invention. Referring to FIG. 4, in step 300, the mobile communication system 12 Determines if it is a good time to receive call records from one or more mobile telephones 10. The mobile communication system 12 will consider the traffic load of the call in a particular service area.

The operator of the mobile communication system 12 will block a specific time period on each day to disallow requesting performance data of call state recording from the mobile phones 10 to the mobile communication system 12 for reasons of system capacity. The communication system 12 must also set up an environment for receiving status data from certain mobile phone users, such as VIP users, users on special call plans or users calling for special call service problems. will be.

Therefore, each mobile phone 10 will sort the schedule to have the state call record data recovered. The schedule may be easily executed because the mobile communication system 12 knows that all mobile phones 10 are identified at the time of system registration because all mobile phones 10 have been turned on.

If in step 302 the criteria of step 300 are not satisfied, the mobile communication system 12 will not require downloads from predetermined mobile phones 10. The mobile communication system 12 checks to confirm that the mobile telephones 10 require downloads of call state performance data from the mobile telephones if they are registered as being "on" in step 304. If the mobile telephone 10 is "on", it is determined in step 306 whether the mobile telephone 10 is connected to the call by the current user.

If the call of the mobile telephone 10 is not connected, the mobile communication system 12 transmits performance data on the current call status of the mobile telephone 10 in step 308. Of course, the mobile phone 10 will delete the contents of the call state portion 20 after the performance data transmission.

One of ordinary skill in the art will understand and appreciate that there are many variations regarding the triggering event and at least the triggering event code storage and the generation of the desired call conditions due to the geographical location information in the mobile phone.

In particular, the mobile phone or the mobile communication system transmits to the call state recorder to the mobile communication system in order to measure and statistically analyze location information of a service having poor service quality to a subscriber (customer).

Preferred embodiments of the invention are shown and described. Modifications made by those skilled in the art are made without departing from the spirit of the invention and the embodiments disclosed above within the scope defined in the following claims.

As described above, the mobile telephone of the present invention provides the service provider statistically with performance data on an area incapable of service, a call cannot be established, a call drop or other service quality deterioration. By analyzing this, there is an advantage that the quality of service can be improved more easily.
