Description

Technical field to which the invention belongs:

This is the method of registering the location of the mobile communication system. It is special: Second, it is about the method of storing the location information of the machine with memory, and so on. Ran Qi recorded in the previous technology that disappeared when you recovered early: ㈣ In iG, 3G and other mobile communication systems, the base station reports the common information of the location registration, area code, etc. to the unit cell (cei 丨). … 'The mobile device is used to check the notification information ... If you move to the same location and register the area, and if there is a mobile location 2: Set the registration signal to send the message to the mobile communication exchange office through the base station. Based on the location registration signal, the active communication exchange bureau displays the information of the subscribers who should carry the device, and the location information of the home area of the same device (hereinafter, the location information of the user ’s device), etc., and registers it in the home location recorder (Homme).

Location Resister; hereinafter referred to as HLR). FIG. 1 shows an example of the configuration of a typical mobile communication system as a schematic block diagram. In this mobile communication system, mobile devices MS1 to MS6 are devices capable of performing bidirectional wireless communication between base stations BS1 to BS6. Each of the base stations BS1 to BS6 can perform wireless communication with the portable devices MSi to MS6 in each of the wireless areas C1 to C6 centered on each of them. The wireless areas C1 to C3 of the base stations BS1 to BS3 are used to form a location registration area (or uniform beer calling area) N1, and the wireless areas C3 to C6 of the base station BS4 to BS6 constitute another location registration area (Or call together

mH! Month Amendment No. 92121768 V. Description of the Invention (2) Change of Term: It is connected with the functions of It and service control etc. Inter-network mobile communication; == ^ access = call from other networks to contract subscribers within the network or roaming MS〇C々 ~ 二 Ϊ from the network, and exchanged through mobile communication within the network局 # θϋςΓ π and Tong ^ ί Road are connected. In addition, the mobile communication network between the Internet and the Internet is connected to the location recorder HLR via a control signal line, such as a note of location information. The home location recorder HLR stores the data of the registration information N1 of the location registration area N1 and the passenger equipment MS1 ~ MS6 of N2, and the location information $, and the mobile communication exchange offices MSC1 ~ MSC2 receive the information from the portable equipment Update of MS6's position registration signal and registration of recorder

Hidden !! At the time of the message to the mobile device MS1, the two base stations BS1 ~ BS3 within the area ... are registered by calling the recorder HLR and registering the area from the location of the guest registered with the mobile device. HLR is a memory that backs up the contents of the home location recorder HLR. The outline of the location registration and transmission procedure in the above-mentioned mobile radio communication will be described with reference to FIG. The base stations BS1 to BS3 notify the mobile station Msi to MS3 of the information for registration of the location and the like by the notification information. As long as the mobile device MS3 (refer to FIG. 1) registered in the location registration area N1 in this state is a location registration processing explanation diagram that can be displayed in FIG. 2 and the mobile device MS3 is moved to the location registration area N2, The notified information of the base station BS4 to BS6 is used to detect the change of the location registration area. Therefore, move 2138-5810-PFl (Nl) .ptc page 6

92121768 __year month correction Station MS3 sends out the position registration signal. The position registration signal is sent to the mobile communication switching station MSC2 through any of the base stations BS4 to BS6. The mobile communication switching center MSC2 executes the confirmation procedure if the receiving location registration signal is received. If the authentication result is normal, the home location recorder HLR instructs the location registration to perform the routine number and location information registration from the exchange office, and returns the location registration reception signal to the mobile device MS. As long as the home location recorder HLR instructs the location registration from the exchange MSC2, the registration routine number and location information of the location registration area where the mobile device MS3 is registered are displayed. As described above, the registration of the mobile device to the location where the mobile device has been moved to another location registration area is completed. Moreover, if there is a message on the mobile device MS3, the internet mobile communication switch GMSC uses the receiving dial-up number to extract the affiliate code (carrying device number) of the mobile device MS3, and based on the subscriber number, The recorder HLR reads out the position information (routine number) of the mobile device MS3 to set the line of the mobile communication switching station MSC2 displayed at the line number. ^ Therefore, the mobile communication switching station MSC2 registers the area N2 with the indicated location, = base, and the stations BS4 to BS6 to make a unified call. With-Qihu, take the machine! § MS3 sends the response signal to the exchange MSC2 through the base station. Based on the response signal, the mobile communication program is set to clear the communication channel, which is described above. 'Even where the mobile device is moved, it is also due to: "The location information of the registered location of the guest registration is 2: Machine Newsletter. ^ The sender of Zheyizhi's other network came.

However, as long as the HLR is restored and re-opened for any reason, such as the failure of the home position recorder HLR, all the memory contents are already set. Therefore, the inner valley of the recorder HLR is backed up in the backup memory} ILR ’in a time unit with a maintenance bureau. When jjLR is reopened, the backup information is used to restore the location information to the home location recorder HLR. However, since the restored location information is poorer than the restored location (current time), the correct location information based on the actual location of the carrying machine at the current time is not restored. In this case, because the backup data of the user's machine position information held by the HLR is used to restore the data while the data is being processed in order to maintain the data, the data is restored to the recorder hlr and reopened. The difference between the current machine position and the call connection loss at the time of becoming a newsletter To be cautious about the registration position of the recorder HLR '(a) Waiting for registration from the location where the device came from ^ Reading to register by location The change of area is carried by I and x §, or (b) waiting for the follow-up message, and whether the registration request is based on whether it is on the portable device 7 or not, is specifically registered in the above-mentioned application location. The location information will be restored to the current location. 1. Synchronization ’will not be able to quickly reset the reset message recorder after the restoration. In addition, there will be 24 1 fiber until the synchronization of the robbers is completed after it exists in the self-connected nodes on the network.

Rev. 92121768, Rev. V. Description of the Invention (13) The setting of “stop stay location information” to stop π ’s repeated stay location information is to update such repeated stay location information with the HLR when it receives the UL (Update Location). , And just where you stayed. In addition, the initial value of the additional column in the database of all participants is Nu 丨. In the implementation form, by updating the processing, for the machine that continues to move for a short period of time, it is expected that the next position information can be used to reduce the loss of movement even after the machine is down due to a temporary failure of the HLR. The process of changing the position of the portable device in the embodiment will be specifically described. FIG. 5 is an explanatory diagram showing an example of a case where the portable device is moved in various regions, and the search is shown in FIG. 6 with columns (1) to (4) formed corresponding to the area arrangement of FIG. 5 The watch system is prepared. Fig. 7 is a diagram for explaining the process of changing the position of the portable device. According to FIG. 7, as long as the HLR of the embodiment receives the UL from the guest location recorder VLR (in the example, the VLR (n) where the mobile is located), in principle, it will update the previous stay location information 104 to the old one. The location information of the previous stay, the current location information 1 〇1 before the UL reception was updated to the location information of the previous stay 1 104, so the new location information is updated as the current location information 1 〇1. Therefore, it is further determined whether the current position information 1 〇1 and the previous stay position " k 1 0 4 are phase specific '. In the case of phase specific, the current position information 1 0 1 is used as the repeated stay position information 1 0 3 And remember. [Prediction of estimated position] On the one hand, when the current position information 101 and the position information 104 just stayed are not equal, the reception time at the time of UL reception and the last access time 1 (the previous UL reception time) are compared. The time difference is calculated by the time stamp, and the time difference is a certain time.

Continuing, FIG. 8 shows a diagram of a portable device calling procedure in the embodiment system, and FIG. 9 shows a diagram of a portable device calling procedure after the system is turned on again. In the normal (at the time of stable) machine position inquiry processing, the HLR is searched just like the conventional Hlr as shown in Fig. 8! Each person keeps the current position information (101) and outputs it. That is, as long as there is a request from the GMSC (SRI (Send Routing Information)), the HLR is based on the current location information of the machine that should be carried by itself, and the PRM (Provi (i Roaming Number)) is established in the established VLR. Based on the prm acknowledge signal returned from the VLR, the SRI acknowledge signal is sent back to the GMSC. However, in the case of HLR failure, in the implementation system, it is the position of the machine when the system is turned on and the machine is called. Inquiry processing, to execute the mobile device calling procedure shown in Figure 9. That is, as long as the hlr system receives the request from the GMSC and requests the SRI, the re-opening of the verification database '' Zhongsi Temple shows 1 2 and the right re-opens The Chinese flag 1 〇2 is the "1" which is not specified in the table. First, the Cancel Location signal is sent to the guest location recorder VLr based on the location information in the same database (existing). (1). Therefore, when there is no Ack response within 3 seconds or when it becomes an error, 'Cancel Location signal is continuously transmitted to the predetermined guest based on repeated stay location information 103 When set recorder VLR (2). In the same manner as in 3 seconds or less No Ack in response to the timely% wrong occasion, or become, in turn Cancel Location signal is sent to the information based on location just stay in the 1〇4

Established guest location recorder VLR (3). Therefore, in the above process, the guest location recorder that originally returned the Ack response (the example shown in FIG. 9 is the guest location recorder VLR (3, the number is registered in the current location information 1 (n, and the ISD (Insert Subscriber Data) signal is sent to the current guest location recorder VLR (3) 'to receive the ISD acknowledge signal. Therefore, the reopening flag in the database DB that should be taken as a carrying device 丨 〇2 can be regarded as a special gift. Π〇π. Moreover, the "Sri acknowledge" signal is returned to the GMSC. In the embodiment, as shown in Fig. 9, the HLR has three pieces of position information corresponding to the portable device. Even if the current position information is incorrect, You can also try the remaining two positions with the highest probability below. By doing this, you can prevent the loss of movement by 3 times the accuracy. Right based on the implementation described above Mode, it can reduce the call processing loss after HLR re-opening more than the conventional technology. This is because not only the existing location information can be used, but a maximum of 3 location information can be processed. Moreover, the backup can be designed at 30 minutes and for a short time. This is because the interval for backing up data to the media, the length of the stop time when HLR failure occurs, the time required to read data from backup media, and If the total time of the re-opened service stop time of hlr is assumed to be about 30 minutes, the probability of the positions of each carrying machine after recovery is present in the current location information or adjacent locations, and the high-speed moving machine (Shinkansen) It is possible to estimate the position of the movement loss even if it is moving
