Description

A method and device for self-adaptation between public network and private network

technical field

The invention relates to the technical field of network communication, in particular to a method and device for self-adaptation between a public network and a private network.

Background technique

The network has increasingly become an indispensable part of people's production and life. In order to meet the diverse needs of use, at present, in some special fields, independent communities or special department units, dedicated networks (dedicated networks for short) are often set up at the same time. network) and shared network (referred to as the public network). When the public network and the private network exist at the same time, it is necessary to determine which network the terminal should access. Generally speaking, in these areas, based on factors such as security, terminals should mainly work on private networks. However, for the current wireless network, the resources of the private network are relatively scarce. Therefore, too many terminals working in the private network at the same time will overload the private network, that is, the private network will be congested, causing users Undesirable phenomena such as stuttering occur in the use of the terminal. At this time, the resources in the public network cannot be fully utilized.

To solve the problem of congestion in the private network, on the one hand, user terminals may actively disconnect from the private network and then connect to the public network. In this way, not only the operation is cumbersome, but also the randomness is large, which cannot guarantee to solve the problem of private network congestion. Moreover, when the private network becomes unobstructed, the terminals in the public network cannot automatically switch to the private network. Although these terminals can return to the private network by shutting down and restarting, if the private network is still congested at this time, it will lead to returning to the private network. At the same time, during the shutdown and restart period, the terminal cannot perform related business operations, which greatly affects the user's use and experience.

On the other hand, when the private network is congested, the private network cannot prevent new user terminals from trying to access the private network. The efficiency of connecting the terminal to the private network is low and greatly affects the user experience of the terminal user.

Therefore, in the process of implementing the present invention, the inventor found that the prior art has at least the following problems: when the existing network system is equipped with private network and public network at the same time, not only cannot effectively solve the congestion problem of the private network, but also when the private network is restored , the terminals in the public network cannot be returned to the private network in time.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are to distinguish two entities with the same name but different parameters or parameters that are not the same, see "first" and "second" It is only for the convenience of expression, and should not be construed as a limitation on the embodiments of the present invention, which will not be described one by one in the subsequent embodiments.

The present invention aims at the problems that the private network congestion and the terminals connected to the public network return to the private network cannot be solved when the private network and the public network are set at the same time, by modifying the broadcasting of the private network and the regular query mode of the public network, the above problems can be solved at the same time, Ultimately, all terminals can be preferentially connected to the private network, and at the same time, the congestion problem caused by too many connected terminals on the private network can be overcome.

Specifically, refer to FIG. 1 , which is a flowchart of an embodiment of a method for adapting a public network and a private network provided by the present invention. The method for adapting the public network and the private network includes:

Step 101, when it is detected that the private network is congested, select some terminals in the private network according to a preset algorithm, and disconnect the data connection of the selected part of the terminals; wherein, the private network refers to a private network, And the terminal should work in the private network first. The congestion refers to the shortage of resources in the private network caused by too many connected terminals or the excessive amount of data accessed by the connected terminals. For user terminals, congestion is manifested as slow data access, or even Caton phenomenon occurs. Here, selecting some terminals refers to reducing the number of terminals connected to the private network in order to solve the congestion problem, and how many terminals need to be selected and which terminal to select need to be determined according to the congestion situation and the preset algorithm. For example: the more severe the congestion, the more terminals may be selected.

Step 102, modify the private network broadcast logo, so that the broadcast logo is set with information that prohibits access to the private network; wherein, the general principle of the terminal connecting to the network is: the network segment will continuously send broadcast signals to the fixed area, when the terminal detects Only when the broadcast signal is received, can the network be connected to the network according to the information contained in the broadcast signal. In the present invention, there will be no new terminal request to connect to the private network during the congestion period, therefore, it is necessary to modify the private network broadcast identifier, that is, set the information prohibiting access to the private network in the private network broadcast; and prepare to connect to the private network If the terminal discovers the information prohibited from accessing the private network contained in the broadcast of the private network, it will not access the private network, but connect to the public network. In this way, the private network will not be congested again, and new terminals can be connected to the resource-rich public network in time.

Step 103, according to the preset time period, the public network sends a load query request to the private network; wherein, the preset time period is a reference value of the query frequency set in advance according to conditions such as network equipment and network usage , and this time period can be adjusted accordingly according to the actual situation. Based on the fact that most of the current core networks only support querying the corresponding communication methods, it is necessary for the public network to send query requests to the private network to make the private network respond. Therefore, under the premise of the existing core network structure, it is easier to adopt this step achieved, and at a lower cost. Of course, by changing the settings of the core network, the private network can actively query the load regularly and feed back the query results to the public network. In this way, the steps of sending the request can be saved, thereby improving the efficiency of self-adaptation between the private network and the public network.

It should be noted that the precondition in step 103 may be the same as step 101, or there may be no precondition. That is to say, the public network can be set to send query requests regularly all the time, or the query step needs to be started only when the private network is over-congested. Alternatively, it is necessary to determine whether there is a terminal (such as a dedicated terminal) that should be connected to the private network in the public network, and only when it is detected that there is a dedicated terminal in the public network, the query step will be started.

Step 104, the private network receives the load query request sent by the public network, and queries the current network load; judges whether the current network load of the private network is less than the preset load threshold; if the current network load is less than the preset load threshold, then execute the step 105.

Step 105, according to step 104, if the current network load is less than the preset load threshold, feed back the congestion relief instruction to the public network, and modify the private network broadcast identifier so that the broadcast identifier is set with information that allows access to the private network ; Wherein, the load threshold is a preset reference value for judging whether the congestion is relieved, for example, if the network resource is 100, if the current terminal needs more than 100 resources, congestion will occur, if the current terminal needs If the resource is lower than 80, it means that there is no congestion, and new terminals can continue to be connected, and when the resource required by the current terminal is between 80 and 100, it means that it is in a congestion period, and new terminals cannot be connected at this time, otherwise it may Congestion occurs. The network load is just a reference standard for judging whether the network is congested, and other judging standards can also be selected according to the background of the existing network technology. Therefore, the network load is not a limitation of the present invention.

Step 106, the public network receives the congestion relief instruction fed back from the private network, and according to the information in the congestion relief instruction, disconnects the connected terminal and reconnects the terminal to the private network. Wherein, the congestion relief instruction is only to indicate that the feedback instruction contains congestion relief information, and is used to prompt the public network that the congestion of the private network has been relieved. When congestion occurs, it is likely that some terminals are connected to the public network. When the private network is uncongested, the terminals that are already connected to the public network will not actively connect to the private network because they cannot recognize when the private network is uncongested. , therefore, the private network needs to send a congestion relief command to the public network, so that the public network disconnects the connected terminals, and then the broadcast based on the private network has been changed to a permitted connection, so these terminals will be reconnected to the private network.

It can be seen from the above-mentioned embodiments that the above-mentioned method for adapting the public network to the private network solves the congestion problem of the private network by disconnecting some connected terminals according to a predetermined algorithm when the private network is congested, and then sets in the private network broadcast There is information prohibiting access to the private network, so that new terminals cannot be connected to the private network, which not only ensures that the private network will not be congested here due to the access of new terminals, but also allows new terminals to directly connect to resource-rich resources. In the public network, the efficiency of network connection management is greatly improved. Based on the congestion of the private network, there may be terminals connected to the public network. Therefore, when the congestion of the private network is relieved, it is necessary to connect the terminals (including terminals connected to the public network and new terminals ready to connect to the network) to the private network. However, the present invention makes the public network send a load query request to the private network according to the preset time period, and the private network will feed back instructions to the public network according to the query results. The network sends a congestion relief command to the public network, and sets information that allows access to the private network in the broadcast identifier, so that new terminals that are ready to connect to the network can connect to the private network. At the same time, after the public network receives the congestion relief command, it will The information in the command releases the connected terminal, and then makes the terminal reconnect to the private network. Therefore, the method of self-adaptation between the public network and the private network can not only effectively solve the congestion problem of the public network, but also enable the terminals in the public network to return to the private network when the congestion of the private network is relieved.

In some optional embodiments of the present invention, the terminals include dedicated terminals and ordinary terminals; wherein, the dedicated terminals are preferentially connected to the private network, and the ordinary terminals are always connected to the public network. In the network system of the present invention, ordinary terminals are always connected to the public network, and dedicated terminals are preferably connected to the private network. Only when the private network is congested, some dedicated terminals will be connected to the public network. Therefore, in this embodiment All terminals refer to dedicated terminals.

In some optional embodiments of the present invention, the step of detecting congestion in the private network includes: presetting a network congestion threshold in the private network; monitoring the current network load in the private network in real time, and judging the network load Whether it is greater than the preset network congestion threshold; if so, it will prompt that the private network is congested; otherwise, continue to monitor the network load in the private network. Based on the continuity and effectiveness of network traffic, it is necessary to set a standard to judge whether congestion occurs. For example, the upper limit of the data volume of the private network is 100, and it can be set that when the data volume requested by the terminal exceeds 110, it is a congestion situation , where 110 is a network congestion threshold. By monitoring the network load of the private network, the occurrence of congestion can be found in time, that is, the congestion problem can be solved in time. Of course, it is also possible to judge in advance directly before the congestion occurs. For example, as long as the network load exceeds a certain threshold, it means that congestion may occur, and the broadcast flag can be directly modified. Wherein, the network load includes one or more of network data traffic, number of connected terminals, response time and other signs that can represent the network status in the private network.

Optionally, the active monitoring method may waste resources, and the passive triggering method can also be used. For example, the connected terminal can judge whether congestion occurs (according to data response time, data flow, etc.), when the private network sends congestion , the terminal sends a congestion command to the private network to indicate the occurrence of congestion.

Further, the terminal refers to smart terminal devices such as mobile phones, tablets, and computers.

In some optional embodiments of the present invention, the step of selecting some terminals in the private network according to a preset algorithm includes: setting different priority labels for all terminals in advance; obtaining the priority of connected terminals Labels, and sort according to the priority of the label from high to low; according to the congestion situation, select a preset number of terminals in the order of priority from low to high. That is, the preset algorithm described in the present invention is selected according to the order in which the priority tags carried by the terminal are arranged. The priority label can be an identity label that is considered to be set, for example: setting the corresponding priority according to the position of the company, or it can be an evaluation of the terminal usage, for example: according to the use time, consumption situation, active status of the terminal user, etc. Degree and so on to set the corresponding priority. The congestion situation refers to the degree of congestion, and the higher the degree of congestion, the more terminals need to be selected. Of course, it is also possible to select the terminals that are sorted one by one until the congestion no longer occurs.

In some optional embodiments of the present invention, the step of selecting some terminals in the private network according to a preset algorithm includes: counting the access time of the terminal to the private network according to the information about the terminal's access to the private network, The level information carried by the terminal, the event type of the terminal; the access time when the terminal is connected to the private network, the level information carried by the terminal, and the event type of the terminal are assigned different weight values, and the total weight of each terminal is obtained; according to In case of congestion, select a preset number of terminals in descending order of total weight. Wherein, the grade information carried by the terminal may be a preset priority or user identity information. The event type of the terminal refers to the type of terminal processing time in the private network, such as sending text messages, surfing the Internet, making phone calls, etc., and some events should not be interrupted normally, such as making phone calls. At this time, a higher weight can be assigned to the event of making a call, so that the end user will not end the call suddenly. Therefore, through the above algorithm, the terminal that can be disconnected can be selected more accurately.

In some optional embodiments of the present invention, the step of modifying the private network broadcast identifier further includes:

Setting the priority label of private network access in the private network, so that the priority label of the private network access is lower than the preset public network access priority label in the public network, so that the terminal preferentially accesses the public network ;

Or, make the priority label of the private network access higher than the preset public network access priority label in the public network, so that the terminal preferentially accesses the private network. In this way, by setting the priority label in the public network, it is possible to further limit the priority level of the terminal for network connection, reduce the error rate, that is, improve the efficiency of self-adaptation between the public network and the private network.

In some optional embodiments of the present invention, after the step of judging whether the current network load of the private network is less than a preset load threshold, the step further includes:

If the current network load is greater than or equal to the preset load threshold, a congestion unrelieved instruction is fed back to the public network. Of course, it is also possible not to feed back information. The public network guidance private network is still in a congested state.

In some optional embodiments of the present invention, the step of disconnecting the connected terminal according to the information in the congestion relief instruction further includes:

Different priority labels are preset for all terminals;

determining the number of terminals accessible to the current private network according to the private network load information included in the congestion instruction;

In the public network, according to the priority labels of the terminals, and according to the number of terminals that can be accessed in the current private network, select the same number of terminals from high to low, and disconnect the data connections of these terminals.

Wherein, the private network load information refers to the ratio of the load occupied by the terminal to the private network load capacity. Through the private network load information, the load margin of the private network can be determined, and then the terminal that can be accessed by the current private network can be calculated. The number of terminals prevents the public network from disconnecting too many terminals, resulting in re-congestion of the private network. Moreover, the present invention enables the public network to select a suitable terminal from a large number of terminals to switch to the private network through the preset priority labels in the terminal. In this way, the orderly and stable self-adaptation between the private network and the public network can be guaranteed, and differentiated management can be carried out for terminals, improving the efficiency of terminal networking management.

In some optional embodiments of the present invention, different priority labels are preset for all terminals;

After the step of modifying the broadcast identifier of the private network so that the broadcast identifier is set with information prohibiting access to the private network, it includes:

After the terminal detects the information prohibiting access to the private network in the broadcast identifier, it judges whether to continue to access the private network according to the priority label level in the terminal;

If the priority level in the terminal is higher than the preset level threshold, continue to access the private network;

Otherwise, access to the private network is prohibited.

For some terminals, based on the identity or level of the user terminal, it is sometimes necessary to ensure that these user terminals are always in the private network. Therefore, by setting different priority labels and setting a level threshold in advance, the When the priority level is higher than the preset level threshold, the terminal will ignore the sign of prohibiting access to the private network set in the private network broadcast, and continue to access the private network. Furthermore, if the private network is congested again, end users with lower levels will be eliminated according to the priority level, so as to ensure that advanced users (end users with relatively high levels) can always connect to the private network. Or, it can also be set so that advanced users can only connect to the private network, but not the public network.

Referring to FIG. 2 , it is a flow chart of another embodiment of the method for adapting the public network and the private network provided by the present invention. The method for adapting the public network and the private network includes:

Step 201, preset a network congestion threshold in the private network; monitor the current network load in the private network in real time;

Step 202, judging whether the network load is greater than a preset network congestion threshold; if so, then execute step 203, otherwise continue to execute judging step 202;

Step 203, according to step 202, prompting that the private network is congested;

Step 204, pre-set different priority tags for all terminals; obtain the priority tags of the connected terminals, and sort according to the priority of the tags from high to low;

Step 205, according to the congestion situation, select a preset number of terminals in order of priority from low to high, and disconnect the data connection of the selected part of terminals;

Step 206, modify the private network broadcast identification, so that the broadcast identification is set with information that prohibits access to the private network, and at the same time set the priority label of the private network access, so that the priority label of the private network access is lower than the specified The preset public network access priority label in the public network allows terminals to access the public network first;

Step 207, according to the preset time period, the public network sends a load query request to the private network;

Step 208, the private network receives the load query request sent by the public network, and queries the current network load;

Step 209, judging whether the current network load of the private network is less than a preset load threshold; if so, perform step 211, otherwise, perform step 210;

Step 210, if the current network load is greater than or equal to the preset load threshold, then feed back the congestion unrelieved instruction to the public network;

Step 211, feed back the congestion relief instruction to the public network, and modify the private network broadcast identifier, so that the broadcast identifier is provided with information that allows access to the private network; at the same time, set the priority label for private network access in the private network, so that The priority label of the private network access is higher than the preset public network access priority label in the public network, so that the terminal preferentially accesses the private network;

Step 212, according to the private network load information included in the congestion instruction, determine the number of terminals that can be accessed by the current private network;

Step 213, according to the priority labels of the terminals in the public network, and according to the number of terminals that can be accessed in the current private network, select the same number of terminals from high to low, and disconnect the data connections of these terminals. These terminals are connected to Private Network.

It can be known from the above embodiments that the method of self-adaptation between the public network and the private network can not only effectively solve the congestion problem of the public network, but also enable the terminals in the public network to return to the private network when the congestion of the private network is relieved. At the same time, the method for self-adaptation between the public network and the private network further improves the efficiency and accuracy of the self-adaptation between the private network and the public network by setting different priorities for the terminal and the private network.

In another aspect of the embodiments of the present invention, as shown in FIG. 3 , a device for adapting a public network to a private network is also provided. The device for adapting the public network to the private network includes:

The congestion processing module 301 is configured to select some terminals in the private network according to a preset algorithm when congestion occurs in the private network, and disconnect the data connections of the selected terminals; and send a broadcast modification instruction to the broadcast modification module 302 ; Send a congestion start instruction to the public network processing module 303;
