Embodiments of the invention

[0033] The description paragraphs of the embodiments of the present invention are entered here. The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative, and are not to be construed as limiting.

1 is a schematic diagram of a device automatic access server system according to a first embodiment of the present invention. The system includes a database server 100, a central server 200 connected to the database server 100, and a central server 200. The terminal 300, the registration machine 400, the plurality of devices 500, and the plurality of servers 600. The central server 200 is disposed in the management registration machine 400, and the notification notification register 400 is changed in the state of the server 600. The registration machine 400 is capable of selecting a suitable server 60 among the plurality of servers 600. 0 is assigned to device 500 for automatic access. The information to be saved in the registration machine 400 is a dictionary pair. The dictionary pair refers to the data structure of the device 500 identification code (ID) and the access server ID. In addition, the access server group and their online status need to be saved. The information in the registration machine 400 needs to save the database. When restarting, it is necessary to obtain corresponding information through the database, and to change the database of the registration machine 400 after the status of the server 600 is changed. specifically:

[0035] The device 500 is configured to send a registration request to the registration machine 400.

[0036] Specifically, the device 500 is configured with an ID of the registrar 400, a network protocol (IP), and necessary authentication information. When the device 500 starts, the registration information is sent to the registrar 400, and the registration message includes at least a registration protocol. .

[0037] The registration machine 400 is configured to verify the registration request, and when the verification passes, combine the load conditions of the plurality of servers 600, and send the data information of the optimal server 600 to the device 500.

[0038] Specifically, the registration machine 400 searches for the corresponding server 600 in the dictionary pair by the ID of the device 500. More specifically, the server 600 that the registration machine 400 is looking for may be the server 600 having a connection history with the device 500, or may be the optimal server 600. The registration machine 400 transmits the data information of the server 600 sought to the device 500.

[0039] Further, the server 600 with the smallest load can be selected as the optimal server according to the load condition of each server 600.

[0040] The data information includes at least the ID, IP, authentication information, and the like of the server 600.

[0041] The device 500 is further configured to send an access request to the server 600 according to the data information, and automatically access the server 600.

[0042] Specifically, the device 500 sends the ID, IP, and authentication information of the access server 600 to the server 60.

0 initiates an access request and connects to server 600.

[0043] The registration machine 400 is configured to update the state of the server 600, and a dictionary pair of the device 400 and the accessed server.

[0044] Specifically, after the device 500 is successfully connected to the server 600, the registration machine 400 updates the dictionary pairs in the memory and the information of the database.

[0045] After the device 500 is successfully connected to the server 600, information such as signaling and media can be exchanged.

[0046] Preferably, the registration machine 400 is specifically configured to verify the registration request according to the registration request sent by the device 500. begging.

[0047] When the verification passes, the registration machine 400 determines whether there is a server 600 that has been assigned (with a connection history) to the device 500.

[0048] If so, the registrar 400 transmits the data information of the assigned server 600 to the device 500.

[0049] If not, the registrar 400 selects the data information of the optimal server 600 and sends it to the device 500. Specifically, if the registrar 400 does not find the corresponding access server 600, and the representative has not previously been assigned, then the weighting algorithm is used to optimize the access server 600 for allocation to achieve an optimal configuration.

[0050] Preferably, the registration machine 400 is further disposed on the detection device 500 to be disconnected from the allocated server. When the device 500 sends a second registration request to the registration machine 400, the registration machine 400 receives the second registration request and verifies the second registration request. When the verification passes, the registration machine 400 determines the device 500 and the allocated server. Whether the time between the 600 broken connections reaches the preset daytime threshold. The inter-turn threshold can be set to 3 minutes or any inter-turn, and the specific time is determined according to the performance index requirements of each system, and the present invention does not impose specific restrictions.

[0051] If yes, the registrar 400 updates the saved information and selects the data information of the optimal server 600 to be sent to the device 500. The optimal server 600 is re-selected for the registrar 400 in conjunction with the load conditions of the plurality of servers.

[0052] If not, the registrar 400 transmits the data information of the allocated server 600 to the device 500, and the registrar 400 does not update the information of the dictionary pair, and the reconnection of the device 500 does not generate a redirection.

[0053] As a further improvement of the embodiment, when the server 600 to which the device 500 has been accessed is down, the device 500 is disconnected from the connected server 600. Device 500 sends a third registration request to registrar 400

[0054] The registration machine 400 verifies the third registration request, and sends the data information of the server 600 and the first valid time to the device 500 when the verification passes, wherein the data information includes at least the ID, IP, verification information, and the like of the server 600. The first active time is for the server 600 to handle the failure.

[0055] The registration machine 400 transmits the data information of the optimal first server to the device 500 to enable the device 500 to access the optimal first server 600. The optimal first server 600 refers to: an optimal server among other servers other than the down server 600.

[0056] When the first valid timeout expires, the device 500 is disconnected from the optimal first server 600. [0057] After the first valid time expires, the registration machine 400 determines whether the server 600 of the downtime is restarted.

[0058] If yes, the restarted server 600 (that is, the server 600 that repairs the failed downtime) is sent to the registration machine.

400 sends a status message. Specifically, the restarted server 600 notifies the registration machine 400 of the status by means of message reporting.

[0059] The registration machine 400 receives the status of restarting the server 600 and updates the status of the restarted server 60 in the memory, and the device 500 is automatically connected to the restarted server 600.

[0060] If no, indicating that the server 600 of the downtime has not handled the fault, the registrar 400 transmits the second valid time of the server of the downtime to the device 500 again, and the server 600 of the second valid day-to-day fingerprint machine It is expected to handle the remaining time of the fault. The device 500 is automatically reconnected to the optimal first server 600, and when the second active time expires, the device 500 is again disconnected from the optimal first server 600.

[0061] After the second valid timeout expires, the registration machine 600 again determines whether the server 600 of the downtime is restarted, and if so, the registration machine 400 receives the restart server 600 (ie, the server 600 that repaired the failed downtime). The state of the restarted server 600 in memory is updated and the device 500 is automatically connected to the restarted server 600.

[0062] If not, the registrar 400 transmits the data information of the optimal server to the device 500 in conjunction with the load conditions of the plurality of servers. The optimal server here may be the optimal first server or other servers.

[0063] The optimal first server in this embodiment can be understood as an excessive server in the process of handling a failure of the server of the downtime, and if the server of the downtime still does not restart after expiration of the second valid time, the registration is performed. The machine can periodically determine whether the server of the downtime is restarted according to the predetermined setting, and continue to send the third effective time to the device... the Nth effective time.

[0064] When the server of the downtime is restarted, and a new device sends a registration request to the registration machine 400, the registration machine 400 assigns the restarted server 600 to the new device to balance the allocation of the devices to the respective servers.

[0065] As a further improvement of the embodiment, when the server 600 and the device 500 are automatically disconnected, the registration machine 400 determines whether the number of automatic disconnection connections reaches a preset number of times threshold.

[0066] If so, the registrar 400 determines that the server 600 reaches the load limit and updates the access capability of the server 600 to the number of access devices. If not, the registrar 400 again allocates the server 600 to the device 500 for access. [0067] Specifically, since the access capability of each access server 600 is certain, if a certain access device capability is reached, if a reconnection occurs, the connection is actively disconnected. The registration machine 400 selects the weighted round robin algorithm to select the access server 600, but the actual weight of the access capability of the access server 600 may deviate from the value set by the central server 200. In this case, the dynamic optimization may be performed. Weight, if a predetermined number of times (for example, 5 times) of disconnected connections are continuously generated during the connection process of the device connected to the access server, it can be determined that the access capability of the access server 600 reaches the maximum, and the access of the access device is maximized. The value of the capability (weight) is dynamically adjusted to the number of access devices for this purpose so that the number of access devices 500 of each access server 600 is more even.

[0068] In other embodiments, if the device 500 is of a large order of magnitude, a plurality of registrars 400 may also be supported, and the plurality of registrars 400 are managed by the central server 200, each registrar 400 managing a group of access servers 600. The registration machine 400 performs the assignment of the access device 500 to the access server 600 within the group.

[0069] The device provided by the embodiment automatically accesses the server. After the device 500 is connected, the registration machine 400 can dynamically select the access server 600 for access by the device 500, thereby avoiding human intervention. In the case where the device 600 is down, when the device 500 is registered again, the registration machine 400 will exclude the corresponding access server 600 of the downtime, and allocate it to other access devices 500 of the device 500, thereby making the device access more. Convenient and flexible, it can also quickly and automatically change access when there is a problem with the server

Load situation, send the optimal server data information to the device, so that the device The server is dynamically accessed, and the most suitable server can be allocated according to the load condition of the server to automatically access the device.

Referring to FIG. 6, a third embodiment of the present invention provides a method for an apparatus to automatically access a server, where the method includes:

[0116] Step 610: The device sends a registration request to the registration machine.

[0117] Specifically, the ID of the registrar, the network protocol (IP), and the necessary verification information are configured in the device, and the device sends the registration information to the registrar when the device is started, and the registration message includes at least the registration protocol.

[0118] Step 620: The registration machine verifies the registration request. When the verification passes, the registration machine combines the load status of the multiple servers, and sends the data information of the optimal server to the device.

[0119] Specifically, the registration machine searches for the corresponding server in the dictionary pair by using the ID of the device. More specifically, the server that the registry is looking for may be a server with a history of connection to the device, or it may be an optimal server. The registration machine sends the data information of the server it is looking for to the device.

[0120] Further, the server with the smallest load may be selected as the optimal server according to the load condition of each server.

[0121] The data information includes at least the ID, IP, authentication information, and the like of the server.

[0122] Step 630: The device sends an access request to the server according to the data information, and automatically accesses the server.

[0123] Specifically, the device initiates an access request to the server by acquiring the ID, IP, and authentication information of the access server, and connects to the server.

[0124] Step 640: Register the machine update server status, and the dictionary pair of the device and the accessed server.

[0125] Specifically, after the device and the server are successfully connected, the registration machine updates the dictionary pair in the memory and the f π information of the database.

[0126] After the device and the server are successfully connected, information such as signaling and media can be exchanged.

[0127] Preferably, referring to FIG. 7, step 620 further includes:

[0128] Step 710: The registration machine verifies the registration request according to the registration request.

[0129] Step 720: When the verification passes, the registration machine determines whether there is a server that has been allocated to the device;

Then, the process proceeds to step 730. If no, the process proceeds to step 740.

[0130] Step 730: The registration machine sends the data information of the allocated server to the device. [0131] Step 740: The data information of the registration machine selecting the optimal server is sent to the device.

[0132] Specifically, if the registrar does not find the corresponding access server, and the representative has not been assigned before, the privilege algorithm is searched for the optimal access server for allocation, and the optimal configuration is achieved.

[0133] Preferably, referring to FIG. 8, step 730 further includes:

[0134] Step 810: The registration machine detecting device is disconnected from the allocated server.

[0135] Step 820: The device sends a second registration request to the registrar.

[0136] Step 830: The registration machine receives the second registration request, and verifies the second registration request.

[0137] Step 840, when the verification passes, the registration machine determines whether the device is disconnected from the allocated server to reach a preset time threshold; if yes, proceeds to step 850, and if not, Enter step

860.

[0138] Specifically, the inter-turn threshold may be set to 3 minutes or any time, and the specific time is determined according to the performance index requirements of each system, and the present invention does not specifically limit.

[0139] Step 850: The registration machine updates the saved information, and selects data information of the optimal server to send to the device. The optimal server is re-selected for the registration machine to combine the load conditions of multiple servers.

[0140] Step 860: The registration machine sends the data information of the allocated server to the device, and the registration machine does not update the information of the dictionary pair, and the device reconnection does not generate a redirection.

[0141] As a further improvement of the embodiment, referring to FIG. 9, the method further includes:

[0142] Step 910: The device detects that the accessed server is down, the device disconnects from the accessed server, and sends a third registration request to the registrar.

[0143] Step 920: The registration machine verifies the third registration request. When the verification passes, the registration machine sends the data information of the server and the first valid time to the device, where the data information includes at least the ID of the server.

, IP, authentication information, etc., the first valid time is the time when the server handles the failure.

[0144] Step 930: The registration machine sends the data information of the optimal first server to the device, so that the device accesses the optimal first server. The optimal first server refers to: an optimal server among servers other than the down server.

[0145] Step 940: When the first valid time expires, the device is disconnected from the optimal first server.

[0146] Step 950: The registration machine determines whether the server of the downtime is restarted. If yes, the process proceeds to step 960. If not, the process proceeds to step 980. [0147] Step 960, the restarted server (ie, the server that repaired the failed downtime) sends a status message to the registrar.

[0148] Specifically, the restarted server notifies the registration machine of the status by means of message reporting.

[0149] Step 970: The registrar receives the status of restarting the server and updates the status of the restarted server in the memory, and the device automatically connects with the restarted server.

[0150] Step 980, the registering machine sends the second valid time of the server of the downtime to the device again, and the server of the second valid daytime 预计 machine is expected to handle the remaining time of the fault.

[0151] Step 990: The device is automatically reconnected with the optimal first server, and when the second valid time expires, the device is disconnected from the optimal first server again.

[0152] When the second valid time expires, the registration machine returns to step 950, and steps 950-990 are repeated, when the number of repetitions reaches a preset number of times (ie, the last judgment), if the registration machine determines that the machine is down. After the server is restarted, the device automatically connects with the restarted server; if the registered machine determines that the downed server is still not restarted, the data of the optimal server is sent to the device according to the load of the multiple servers, where The optimal server can be an optimal first server or another server.

[0153] Preferably, if the preset number of repetitions is set to repeat 1 time, after step 990, the following steps are further included:

[0154] The registration machine determines whether the server of the downtime is restarted;

[0155] If yes, the registrar receives a status message sent by the restart server, and updates the status of the restarted server in the memory, and the device is automatically connected to the restarted server; [0156] The registration machine combines the load conditions of the multiple servers to send the data information of the optimal server to the device.

[0157] When the server of the downtime is restarted, and a new device sends a registration request, the registration machine assigns the restarted server to the new device to balance the allocation of the device to each server.

[0158] As a further improvement of the embodiment, referring to FIG. 10, the method further includes:

[0159] Step 1010: The server automatically disconnects from the device.

[0160] Step 1020: The registration machine determines whether the number of times of the automatic disconnection connection reaches a preset number of times threshold; if yes, proceeds to step 1030, and if no, proceeds to step 1040.

[0161] Step 1030, the registration machine determines that the server reaches the load upper limit, and updates the access capability of the server. The force is the number of access devices, and the optimal server is selected among the remaining servers to be assigned to the device.

[0162] Step 1040: The registration machine allocates the server to the device for access again.

[0163] Specifically, since the access capability of each access server is certain, if a certain access device capability is reached, if a reconnection occurs, the connection is actively disconnected. The registration opportunity selects the weighted round robin algorithm to select the access server, but the real weight of the access server's access capability will deviate from the value set by the central server. In this case, the weight can be dynamically optimized. A disconnected connection occurs in a preset number of times (for example, 5 times) during the connection process of the device on the access server, and it can be determined that the access capability of the access server reaches the maximum, and the value of the access capability (weight) of the device is determined. Dynamically adjust the number of access devices for this purpose, so that the number of access devices of each access server is more balanced.

[0164] The method for automatically accessing a server by the device provided by the embodiment, after the device is accessed, the registration machine can dynamically select and select an access server for accessing the device, thereby avoiding human intervention, and the access server is down. In this case, when the device is re-registered, the registration opportunity excludes the corresponding access server of the downtime and allocates it to other access devices of the device, thereby making the access of the device more convenient and flexible, and when the server has problems, Fast and automatic conversion access.

[0165] Referring to FIG. 11, a method for automatically accessing a server by using a device according to a fourth embodiment of the present invention is applicable to a registration machine, but is not limited to a registration machine, and the method includes:

[0167] Step 1120: Verify the registration request.

[0168] Specifically, the verification is performed according to the verification information carried in the registration request.

[0169] Step 1130: When the verification passes, combining the load conditions of the multiple servers, the data information of the optimal server is sent to the device, so that the device automatically accesses the server.

[0170] Specifically, the corresponding server is searched for in the dictionary pair by using the ID carried in the registration request. The server you are looking for can be a server with a history of connection to the device, or it can be an optimal server. Send the data information of the server you are looking for to the device.

[0171] Further, the server with the smallest load may be selected as the optimal server according to the load condition of each server.

[0172] The data information includes at least the ID, IP, authentication information, and the like of the server. [0173] Step 1140: Update the status of the server, and a dictionary pair of the device and the accessed server.

[0174] Specifically, the device initiates an access request to the server by acquiring the ID, IP, and authentication information of the access server, and connects to the server. After the device and the server are successfully connected, the dictionary pairs in the memory and the database information are updated.

[0175] After the device and the server are successfully connected, information such as signaling and media can be exchanged.

[0177] Step 1210: Determine whether there is a server that has been allocated to the device; if yes, go to 1220, if no, go to step 1230.

[0178] Step 1220: Send data information of the allocated server to the device, so that the device automatically accesses the server.

[0179] Step 1230: Select data information of the optimal server to send to the device, so that the device automatically accesses the server.

[0180] Specifically, if the corresponding access server is not found, and the representative has not been allocated before, the weighting algorithm is searched for the optimal access server for allocation, and the optimal configuration is achieved.

[0181] Preferably, referring to FIG. 13, the method further includes:

[0182] Step 1310: Detect that the device is disconnected from the allocated server.

[0183] Step 1320: Receive a second registration request sent by the device.

[0184] Step 1330: Verify the second registration request.

[0185] Step 1340, when the verification passes, determine whether the device is disconnected from the allocated server to reach a preset time threshold; if yes, enter 1350, and if no, proceed to step 1360. .

[0186] Specifically, the inter-turn threshold may be set to 3 minutes or any inter-day, and the specific time is determined according to the performance index requirements of each system, and the present invention does not specifically limit.

[0187] Step 1350: Update the saved information, and select the data information of the optimal server to send to the device.

[0188] Step 1360: Send the data information of the allocated server to the device, and do not update the information of the dictionary pair, and the device reconnection does not generate a redirect.

[0189] As a further improvement of the embodiment, referring to FIG. 14, the method further includes:

[0190] Step 1410: Receive a message that the server sent by the device is down, and the device automatically disconnects from the server. [0191] Specifically, when the server that the device has accessed is down, the device detects that the accessed server has a downtime and sends a message of the downtime, and receives the message of the downtime.

[0192] Step 1420: Update a status of the accessed server, and a dictionary pair of the device and the accessed server.

[0193] Step 1430: Receive a third registration request sent by the device.

[0194] Step 1440, verifying the third registration request.

[0195] Step 1450: When the verification passes, send the data information of the server and the first valid time to the device. The data information includes at least a server ID, an IP, an authentication information, and the like, and the first valid time is a time when the server processes the fault.

[0196] Step 1460: Send data information of the optimal server to the device, so that the device accesses the optimal first server.

[0197] Step 1470, when the first valid time expires, the device is disconnected from the optimal first server.

[0199] Step 1490: Receive a status message sent by the restarted server, and update a status of the restarted server in the memory, and the device is automatically connected to the restarted server.

[0200] Step 1400: Send a second active time of the restarted server to the device, and the device is automatically reconnected with the optimal first server, when the second valid time expires In other words, the device is disconnected again from the optimal first server.

[0201] When the second valid time expires, return to step 1480, and repeat to step 1490, or step 1400, when the number of repetitions reaches a preset number of times (ie, the last judgment), if the downtime is determined Rebooting the server, receiving a status message sent by the restart server, and updating the status of the restarted server in the memory, and the device is automatically connected to the restarted server; if it is determined that the downtime is If the server is not restarted, the data of the optimal server is sent to the device according to the load of the multiple servers. Here, the optimal server may be the optimal first server or other servers.

[0202] Preferably, if the preset number of repetitions is set to repeat 1 time, after step 1400, Next steps:

[0203] determining whether the server of the downtime is restarted;

[0204] if yes, receiving a status message sent by the restart server, and updating a status of the restarted server in the memory, and the device is automatically connected to the restarted server;

[0205] If no, the data information of the optimal server is sent to the device according to the load situation of the multiple servers.

[0206] When the server of the downtime is restarted, and a new device sends a registration request, the restarted server is assigned to the new device to balance the allocation of the device to each server.

[0207] As a further improvement of the embodiment, referring to FIG. 15, the method further includes:

[0208] Step 1510: The detection server and the device are automatically disconnected.

[0209] Step 1520: Determine whether the number of times of the automatic disconnection connection reaches a preset number of times threshold; if yes, go to 1530, if no, go to step 1540.

[0210] Step 1530, the server reaches the load limit, and updates the access capability of the server to the number of access devices.

And select the optimal server assigned to the device in the remaining servers.

[0211] Step 1540: Assign the server to the device for access again.

[0212] Specifically, since the access capability of each access server is certain, if a certain access device capability is reached, if a reconnection occurs, the connection is actively disconnected. The weight can be dynamically optimized. If a predetermined number of times (for example, 5 times) of disconnected connections are continuously generated during the connection process of the device connected to the access server, it can be determined that the access capability of the access server reaches the maximum. The value of the access capability (weight) is dynamically adjusted to the number of access devices for each port, so that the number of access devices of each access server is more balanced.

[0213] The method for automatically accessing the server by the device in this embodiment is to verify the registration request by receiving a registration request sent by the device, and send the data of the optimal server to the device when the verification passes, combined with the load situation of multiple servers. The information is such that the device automatically accesses the server, and the most suitable server can be allocated according to the load condition of the server to automatically access the device.
