Wherein, the regional codes corresponding to different regions are different from each other. In a possible embodiment, the area is divided according to administrative districts, such as country, province, city; in other possible embodiments, the area is divided according to longitude and latitude, for example, every 15 °. The embodiment of the present invention does not limit the specific area division manner.

Operator coding: codes assigned to different operators for distinguishing between different operators. In different regions, the operator codes corresponding to the same operator are different.

The APN codes involved in the embodiment of the invention are codes distributed by different APNs, and the APN codes corresponding to different APNs are different from each other.

Area code: and the numerical value calculated according to the regional code, the operator code and the APN code is used for identifying the region where the terminal access network is located. When any one of the area code, the operator code and the APN code is changed, the area code is also changed. In the embodiment of the invention, the area code is generated by the server and is issued to the terminal, and the area code is stored by the terminal.

Referring to fig. 1, a system architecture diagram of an access system including a terminal 110, a server 120 and a plurality of access points 130 according to an embodiment of the present invention is shown.

The terminal 110 is an electronic device having an internet access function. The electronic device is a smart phone, a tablet computer, an MP3 player (Moving Picture Experts Group Audio Layer III, motion Picture Experts compression standard Audio Layer 3), an MP4 player (Moving Picture Experts Group Audio Layer IV, motion Picture Experts compression standard Audio Layer 4), a portable personal computer, or the like. In the embodiment of the present invention, a client is installed in the terminal 110, and the client may be a client for a user to download an application program, and in actual implementation, the client may also be other types of clients, such as a social networking client, a video playing client, a news client, or a shopping client, and the like, which is not limited in this embodiment.

The terminal 110 and the server 120 are connected by a wired or wireless network.

The server 120 is a server, a server cluster composed of a plurality of servers, or a cloud computing center. In this embodiment of the present invention, the server 120 is a background server of a client in the terminal 110, and is configured to allocate an access point to the terminal 110 according to an access request sent by the terminal 110, so that the terminal 110 performs data communication with the allocated access point.

The server 120 is connected to each access point 130 via a wired or wireless network.

The access point 130 is a server for providing a service to a client in the terminal 110. Wherein the access points 130 are distributed in different areas and access networks provided by different operators.

In one possible implementation, as shown in fig. 1, the server 120 includes an access server 121 and a scheduling server 122, where the access server 121 is connected to the scheduling server 122, and the scheduling server 122 is connected to each access point 130. The access server 121 is configured to receive an access request sent by the terminal 110, detect whether the location of the terminal 110 changes according to the access request, and request the scheduling server 122 to reallocate an access point to the terminal 110 when detecting that the location of the terminal 110 changes; the scheduling server 122 is configured to allocate an optimal access point 130 to the terminal 110 according to parameters such as communication time consumption, request amount, load, processor utilization rate, and memory utilization rate of each access point 130, so that the terminal 110 communicates with the allocated access point 130.

Optionally, the wireless or wired networks described above use standard communication techniques and/or protocols. The Network is typically the Internet, but may be any Network including, but not limited to, a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), a mobile, wireline or wireless Network, a private Network, or any combination of virtual private networks. In some embodiments, data exchanged over a network is represented using techniques and/or formats including Hypertext Mark-up Language (HTML), Extensible markup Language (XML), and the like. All or some of the links may also be encrypted using conventional encryption techniques such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet protocol Security (IPsec). In other embodiments, custom and/or dedicated data communication techniques may also be used in place of, or in addition to, the data communication techniques described above.

Referring to fig. 2, a flowchart of an access method according to an embodiment of the present invention is shown, where the access method is used in the access system shown in fig. 1 for example, and the method includes:

in step 201, the terminal sends an access request to the server, where the access request is used to request allocation of an access point.

In a possible implementation, when the terminal accesses the network and detects that the client is in the running state, the terminal sends an access request to the server through the client, and requests the server to allocate an access point for the server. The access request includes a first region code locally stored by the client, and the first region code is generated by the server and is used for indicating a region where the access network is located when the terminal last sends the access request (i.e., indicating the region where the terminal last sends the access request is located).

In other possible embodiments, since the first area code is generated by the server, after the server generates the first area code, the terminal identifier may be stored in association with the first area code. The server can find the first area code corresponding to the terminal according to the terminal identification only by carrying the terminal identification in the access request sent by the subsequent terminal to the server.

It should be noted that, when the terminal first sends the access request to the server, since the local area code generated by the server is not stored, the first area code does not need to be carried in the access request sent to the server or the first area code is empty.

In step 202, the server receives an access request sent by the terminal.

In a possible implementation manner, the server detects whether the received access request includes the first area code, and when the access request includes the first area code, the server needs to determine whether it needs to reallocate the access point to the terminal according to the location change condition of the terminal, and execute the following step 203; when the access request does not contain the first area code or the first area code is empty, the server allocates an access point for the terminal according to the outlet IP address of the terminal.

And step 203, the server acquires a first area code corresponding to the terminal according to the access request.

In a possible implementation manner, when an access request sent by a terminal contains a first area code, a server directly acquires the first area code from the access request; when the access request sent by the terminal does not contain the first area code but contains the terminal identifier, the server searches the first area code corresponding to the terminal identifier from the database according to the terminal identifier.

And step 204, the server calculates a second area code according to the outlet IP address of the terminal.

And when receiving the access request, the server acquires an outlet IP address of the terminal, wherein the outlet IP address is the IP address of the terminal in the current access network, and the outlet IP address is a public network IP address.

In one possible embodiment, the server stores an IP address database, and the IP address database includes a correspondence between an IP address and a regional code, an operator code, and an APN code. After the outlet IP address of the terminal is obtained, the server searches the area code, the operator code and the APN code corresponding to the outlet IP address, and calculates a second area code of the terminal based on the searched code, wherein the second area code is used for indicating the area where the terminal is currently accessed to the network.

In step 205, the server detects whether the first area code is the same as the second area code.

Since the first region code indicates the region where the terminal last sent the access request, and the calculated second region code indicates the region where the terminal currently sent the access request, the server can determine whether the location of the terminal has changed (essentially, detect whether the network to which the terminal has accessed has changed) by comparing whether the first region code is the same as the second region code.

When detecting that the first area code is different from the second area code, the server determines that the area where the terminal is located is changed (compared with the last time of sending the access request), in order to improve the access quality of the terminal, the server needs to reallocate the access point for the terminal, and executes the following step 206; when detecting that the first region code is the same as the second region code, the server determines that the region in which the terminal is located has not been changed (compared to when the access request was last sent), and follows the access point that was last allocated for the terminal.

And step 206, if the first area code is different from the second area code, the server reallocates the access point for the terminal according to the export IP address.

In a possible implementation manner, the server dynamically collects parameters such as communication time consumption of the terminal and the access point, request quantity of the access point, load, processor utilization rate and memory utilization rate during operation, so that the optimal access point is allocated to the terminal by combining the exit IP address of the terminal on the basis of the parameters, and the allocated IP address of the access point is fed back to the terminal.

Step 207, the terminal receives the access point distributed by the server.

When the server detects that the area of the terminal is changed, the access point is the access point redistributed by the terminal. Optionally, when the server detects that the area where the terminal is located is not changed, the access point returned by the server is consistent with the access point allocated last time.

And step 208, the terminal accesses according to the distributed access point.

And according to the obtained access point, the terminal directly performs data communication with the access point, and correspondingly, the access point provides corresponding service for the terminal.

In summary, in the embodiments of the present invention, after receiving an access request sent by a terminal, a server obtains a first region code of the terminal according to the access request, and calculates a current second region code of the terminal according to an exit IP address of the terminal, determines whether a region in which the terminal is located is changed by detecting whether the first region code is the same as the second region code, and reallocates an access point to the terminal when the location in which the terminal is located is changed, thereby implementing cloud access scheduling, improving access quality of the terminal, and avoiding a problem of excessive processing pressure caused by frequent reallocation of the access point by the server when the location in which the terminal is located is not changed.

Referring to fig. 3, a flowchart of an access method according to an embodiment of the present invention is shown, where the access method is used in the access system shown in fig. 1 for example, and the method includes:

in step 301, the terminal sends an access request to the server, where the access request is used to request allocation of an access point.

Step 302, the server receives an access request sent by the terminal.

And step 303, the server acquires a first area code corresponding to the terminal according to the access request.

The implementation of steps 301 to 303 is similar to that of steps 201 to 203, and this embodiment is not repeated herein.

Illustratively, as shown in fig. 4, the server acquires that the first region code corresponding to the terminal is "351000015008" according to the access request. Step 304, the server acquires the outlet IP address of the terminal.

In a possible implementation manner, the access request sent by the terminal conforms to a pre-agreed format, and after receiving the access request, the server obtains the egress IP address of the terminal from a predetermined field of the access request.

For example, when the terminal accesses a WiFi (Wireless Fidelity) network provided by the routing device, the egress IP address is a public network IP address of the WiFi network.

Illustratively, as shown in fig. 4, after the terminal 410 sends an access request to the server 420, the server 420 obtains that the egress IP address of the terminal is 10.1.1.1 according to the access request.

Step 305, the server searches for a region code, an operator code and an APN code corresponding to the exit IP address, where the APN code is used to indicate a mode of accessing the terminal to the network.

In the internet, each large operator corresponds to a respective IP address field, and divides the IP addresses in the IP address fields based on the geographic position and the access mode. Therefore, based on the export IP address of the terminal, the server can determine the operator to which the terminal currently accesses the network, the region to which the terminal currently accesses, and the way in which the terminal accesses the network.

In a possible implementation manner, the server obtains the corresponding relationship between the IP address and the area identifier, the operator identifier and the APN provided by each large operator in advance, and allocates respective codes to the obtained area identifier, the operator identifier and the APN, so as to construct the corresponding relationship between the IP address and the area code, the operator code and the APN code, and store the corresponding relationship in the IP address database. Illustratively, the data storage structure of the IP address database is shown in table one.

Watch 1

IP address	Region coding	Operator coding	APN coding
				IP A	Regional code A	Operator code B	APN code C
IP B	Regional code A	Operator code D	APN code E
				IP C	Regional code F	Operator code G	APN code C

After the server acquires the outlet IP address of the terminal, the server searches the area code, the operator code and the APN code corresponding to the outlet IP address from the IP address database. Optionally, for convenience of subsequently calculating a corresponding region code according to the region code, the operator code and the APN code, the codes all adopt digital codes.

Illustratively, as shown in fig. 4, the server 420 acquires the area code "349", the operator code "11", and the APN code "08" from the IP address database according to the acquired egress IP address.

Step 306, the server calculates a second area code according to the area code, the operator code and the APN code.

In a possible implementation manner, a region code calculation formula is preset in the server, and after the searched region code, operator code and APN code are found, the server calculates a second region code by using the region code calculation formula, where the second region code is used to indicate a region where the terminal is currently located.

Illustratively, the local area code calculation formula is: when the area code is area code × 1000000000+ carrier code × 1000+ APN code, the second area code calculated by the server 420 is 349000011008 as shown in fig. 4.

In step 307, the server detects whether the first region code is the same as the second region code.

After the first area code and the second area code of the terminal are obtained through the steps 301 to 306, the server determines whether the area where the terminal is located changes by detecting whether the first area code is the same as the second area code.

When detecting that the first region code is different from the second region code, the server executes the following steps 308 to 312 to reallocate the access point for the terminal; when detecting that the first region code is the same as the second region code, the server performs step 315 described below.

Illustratively, as shown in fig. 4, the first area code obtained by the server is 351000015008, and accordingly, the server detects that the first area code is different from the second area code.

Step 308, if the first area code is different from the second area code, the server obtains the communication time between the exit IP address and each access point cluster.

In a possible implementation manner, the access points providing service for the client in the terminal are aggregated in the form of access point clusters, and the access point clusters are distributed and arranged in different regions. In an actual implementation process, the access point cluster is represented as a computer room including a plurality of access points (servers), wherein in the same access point cluster, the areas where the access points are located are the same, the operators belonging to the same are the same, but the IP addresses are different.

During the operation process of the server, the communication consumed time of each terminal and each access point in the access point cluster is dynamically collected, and the communication consumed time is stored in a communication consumed time database (historical communication consumed time), wherein the communication consumed time is the average communication consumed time of the terminal and each access point in the access point cluster. Schematically, the storage structure of the communication time consumption database is shown in table two.

Watch two

In a possible implementation manner, after determining the attribution information of the egress IP address according to the acquired egress IP address, the server acquires the communication time consumption with each access point cluster (i.e., a computer room) from the communication time consumption database according to the attribution information.

And 309, the server determines the target access point cluster according to the communication time consumption.

In one possible implementation mode, the server determines an access point cluster with communication time consumption lower than a preset time as a target access point cluster; or, the server determines the access point cluster with the shortest communication time consumption as the target access point cluster. Wherein the predetermined time is preset by a developer, for example, the predetermined time is 100 ms.

After the target access point cluster is determined through the mechanism, the server only needs to select the target access point from the target access point cluster subsequently, and does not need to select the target access point according to the access states of all the access points, so that the processing pressure of the server is reduced.

Illustratively, as shown in fig. 4, the server determines, according to the second region code and the data stored in the communication time consumption database, the access point cluster with the shortest communication time consumption as the target access point cluster, which includes the access points A, B, C and D.

In step 310, the server determines a target access point according to the access state of each candidate access point in the target access point cluster.

In order to further improve the access quality of the terminal, after the target access point cluster is determined, the server further obtains the access state of each candidate access point in the target access point cluster, and determines the candidate access point with the optimal access state as the target access point. The load of the candidate access point with the optimal access state is lower than a first threshold, the request amount is smaller than a second threshold, the processor utilization rate is lower than a third threshold, and/or the memory utilization rate is lower than a fourth threshold.

In one possible embodiment, as shown in fig. 5, the present step comprises the following steps:

in step 310A, the server obtains access state parameters of each candidate access point, where the access state parameters include at least one of a request amount, a load, a processor utilization rate, and a memory utilization rate.

Optionally, the access point cluster reports the access state parameters of each access point to the server at predetermined time intervals (for example, 5 minutes), and the server updates and stores the access state parameters, where the reported access state parameters include at least one of a request amount, a load, a processor utilization rate, and a memory utilization rate.

And after the target access point cluster is determined, the server acquires the access state parameters of each candidate access point from the cache.

Illustratively, the access state parameters obtained by the server to each candidate access point are shown in table three.

Watch III

Access point	Request volume	Load(s)	Processor utilization	Memory usage rate
					Access point A	1000	500	10％	10％
Access point B	5000	1500	25％	40％
					Access point C	2000	800	50％	50％
Access point D	3500	1000	10％	10％

And step 310B, the server calculates the access scores of the candidate access points in a weighting manner according to the access state parameters and the corresponding weights.

Further, the server calculates access scores of the candidate access points based on the acquired access state parameters. Optionally, the higher the access score, the higher the access quality of the candidate access.

In a possible implementation manner, the weights corresponding to different types of access state parameters are different, and in the calculating of the access score, the server calculates the access score in a weighting manner according to the parameter values and the weights corresponding to the parameter values.

Optionally, the request amount, the load, the processor utilization rate, and the memory utilization rate are in inverse proportional relation with the access score, that is, the larger the request amount is, the larger the load is, the higher the processor utilization rate is, and the higher the memory utilization rate is, the lower the calculated access score is.

In step 310C, the server determines the target access point based on the access score.

In one possible implementation, the server determines the candidate access point corresponding to the highest access score as the target access point.

Illustratively, as shown in fig. 4, the server obtains access scores corresponding to the access points A, B, C, D by weighting calculation according to the access state parameters corresponding to the access points, and determines the access point a corresponding to the highest access score as the target access point.

In step 311, the server returns the IP address of the target access point to the terminal.

Illustratively, as shown in fig. 4, the server 420 returns the IP address of the target access point a to the terminal 410 so that the terminal communicates with the target access point according to the IP address.

Because the communication time consumption of the machine room (access point cluster) where the target access point is located and the terminal is low, and the access state of the terminal is good, the terminal has high speed of accessing the target access point, and can have good access quality.

The server sends the second area code to the terminal, step 312.

When the first area code is different from the second area code, the first area code stored in the terminal cannot accurately indicate the current area of the terminal, and when an access request is subsequently sent, if the first area code is still used, the server frequently reallocates the access point. In order to avoid the above problem, in a possible implementation manner, the server returns the IP address of the target access point to the terminal, and simultaneously returns the second area code calculated in step 306 to the terminal, so that the terminal updates the locally stored area code.

In another possible embodiment, when the server stores the correspondence between the terminal identifier and the area code, the server replaces the first area code corresponding to the terminal with the second area code when the first area code is different from the second area code. The embodiments of the present invention are not limited thereto.

And step 313, the terminal receives the second area code sent by the server.

In step 314, the terminal replaces the first region code with the second region code.

And when the second area code sent by the server is received, the terminal knows that the locally stored first area code is invalid and replaces the first area code with the second area code. When subsequently requesting to assign an access point, the terminal adds the second region code to the access request.

Step 315, if the first area code is the same as the second area code, the server returns the last access point allocated to the terminal.

When the first area code is the same as the second area code, the area where the terminal is located is the same when the access request is sent last time, in order to avoid processing resource waste caused by frequent reconfiguration of the access point, the server returns the access point which is allocated for the terminal last time to the terminal, and good access quality can still be obtained when the terminal is communicated with the access point.

In other possible embodiments, the IP address of the access point that has communicated recently is stored in the client that the terminal operates, when it is detected that the first area code is the same as the second area code, the server sends a reuse instruction to the terminal, and after receiving the reuse instruction, the terminal communicates with the corresponding access point according to the stored IP address.

In the embodiment, the server determines the target access point cluster according to the communication time consumption of the terminal and each access point cluster, and further calculates the access score of each candidate access point according to the access state parameter of each candidate access point in the target access point cluster, so that the access point with higher communication speed and better access state is returned to the terminal based on the access score, and the access quality of the terminal is further improved; meanwhile, the access of the terminal to an access point with heavier load, larger request amount or abnormal access is avoided through cloud scheduling, so that the dynamic disaster tolerance capability of the whole access system is improved.

In the above embodiment, only one server is taken as an example for explanation, in an actual implementation process, as shown in fig. 1, the server 120 may further include an access server 121 and a scheduling server 122, and accordingly, referring to fig. 6, it shows a flowchart of another possible access method of this embodiment, and as shown in fig. 6, the method includes:

step 601, the terminal sends an access request to the access server.

Step 602, the access server receives an access request sent by the terminal.

Step 603, the access server obtains the first area code corresponding to the terminal according to the access request.

Step 604, the access server obtains the exit IP address of the terminal.

Step 605, the access server searches for the area code, the operator code and the APN code corresponding to the exit IP address, where the APN code is used to indicate the mode of the terminal accessing the network.

Step 606, the access server calculates a second region code based on the region code, the operator code and the APN code.

In step 607, the access server checks whether the first area code is the same as the second area code.

Step 608, if the first region code is different from the second region code, the access server sends an access point scheduling request to the scheduling server, where the access point scheduling request includes an exit IP address.

Step 609, the scheduling server obtains the communication time consumption of the exit IP address and each access point cluster.

And step 610, the scheduling server determines the target access point cluster according to the communication time consumption.

Step 611, the scheduling server determines the target access point according to the access status of each candidate access point in the target access point cluster.

Step 612, the scheduling server returns the IP address of the target access point to the access server.
