an access gateway: i.e. the servers that ultimately need to be allocated to the device;

access gateway group: any number of combinations of access gateways of the same category. All access gateways in the same access gateway group are required to have the same function, and during distribution, one access gateway with the lowest load is selected from the access gateway group to be distributed to equipment;

strategy: the method and the device are used for matching the rule of a certain information field of the equipment, the matching rule usually has the modes of character string matching, integer range judgment and the like, and the embodiment of the invention does not limit the mode of the matching rule of the field and can be established in specific implementation; matching rules between similar strategies can also be overlapped, for example, it is possible to configure two strategies (3< a <10) and (7< a <15), if the value of field a is 8, both strategies can be matched;

policy group: any number of combinations of policies. Only one policy group is finally matched according to the equipment information, and then one access gateway group is uniquely searched according to the policy group. The following rules are followed for policy matching in the policy group: the same type of strategies are related to one or more (namely, only one strategy is matched); the relationships between the heterogeneous policies are matches (i.e., the heterogeneous policies that must be configured all match).

The strategy family: the unique identification of a certain policy type in a certain policy group, the transfer between the policy group and the policy, and the actual allocation of the policy is mapped to the policy family according to the different policy types.

As shown in fig. 1, the access gateway allocation method according to the embodiment of the present invention includes the following processes:

step 101, an access gateway management system GMS sets a corresponding relation between an access gateway group and a strategy group, and maintains the online state and load information of each access gateway in each access gateway group;

102, a GMS acquires an access gateway address acquisition request carrying equipment information sent by equipment, matches the equipment information with a policy group, and determines the policy group matched with the equipment information;

step 103, the GMS searches for an access gateway group corresponding to the determined policy group according to the correspondence, and allocates an access gateway with the lowest load that is online in the access gateway group to the device according to the online status and load information of each access gateway in the access gateway group.

Specifically, in step 101, the setting, by the access gateway management system GMS, of the correspondence between the access gateway group and the policy group includes the following steps:

step 1, the GMS configures an access gateway group and an access gateway, specifically including the following processing: newly building an access gateway group and an access gateway, setting the initial state of the access gateway to be offline and the load to be 0, and configuring an access gateway address; adding the access gateway into the newly-built access gateway group;

step 2, the GMS configures the policy group and the policy, which specifically includes the following processing: creating a strategy group, creating a corresponding strategy family according to the strategy type, adding the strategy family into the created strategy group, and creating a default strategy for each strategy family; creating a strategy corresponding to a certain strategy type, searching a strategy family corresponding to the strategy type, and adding the created strategy into the searched strategy family, wherein if the strategy family has a default strategy, the default strategy is modified into the strategy needing to be added, and if the strategy family does not have the default strategy, a strategy is newly added into the strategy family;

step 3, the GMS sets a correspondence between the access gateway group and the policy group, which specifically includes the following processing: and configuring the policy groups to the access gateway groups, wherein one policy group can only be configured to one gateway group, and one access gateway group can be configured with a plurality of policy groups.

In step 101, the step of the GMS maintaining the online status and the load information of each access gateway in each access gateway group specifically includes: the GMS receives the load information reported by the access gateway at regular time, and judges the online state of the access gateway according to whether the access gateway reports the load information at regular time; and the GMS stores the acquired load information and online state.

Step 102 includes the following processes: the GMS acquires the equipment information carried in the request according to the access gateway address sent by the equipment, carries out strategy matching on fields in the equipment information respectively, carries out strategy family matching according to the matched strategies respectively, carries out strategy group matching after summarizing according to the matched strategy families, and selects one strategy group with the highest priority from all the matched strategy groups as a strategy group finally matched with the equipment information. The method specifically comprises the following steps:

step 1, the GMS acquires a field in the equipment information, and searches a policy table corresponding to the field according to the policy type table, wherein the policy type table comprises: the policy type, the policy table and the one-to-one correspondence between the fields;

step 2, the GMS searches one or more matching strategies matched with the field according to the strategy table, if the field has a field which is not matched with any strategy, the field is directly ignored, wherein the strategy table comprises: strategies and corresponding relations between the self-defined strategy rules;

step 3, the GMS generates a strategy family matching data table, wherein the strategy family matching data table comprises: the strategy type and the corresponding relation between the strategy type and the matching strategy of each field, and the strategy type without the matching strategy is corresponding to the supplemented default strategy;

step 4, the GMS searches, according to the policy type of each piece of data in the policy family matching data table and the matching policy/default policy corresponding to the policy type of each piece of data, one or more policy families matching both the policy type of the piece of data and the matching policy/default policy corresponding to the policy type of the piece of data from the policy family table and the policy family and policy relationship table, and determines that the device information cannot be matched to a corresponding policy group if any piece of data in the policy family matching data table is not matched to a policy family, wherein the policy family table includes: the corresponding relation between the strategy family and the strategy type, the strategy family and strategy relation table comprises: the corresponding relation between the strategy family and the strategy;

step 5, the GMS searches one or more policy groups matched with each policy group from the policy group and the policy group relationship table according to the matched one or more policy groups, and if a certain policy group is not matched with a policy group, it is determined that the device information cannot be matched with the corresponding policy group, where the policy group and the policy group relationship table include: a one-to-one correspondence between policy groups and policy families;

and 6, the GMS searches one or more strategy groups which exist simultaneously in the strategy groups matched with each strategy family, selects the strategy group with the highest priority from the one or more strategy groups according to the priority as the strategy group which is finally matched with the equipment information, and if one or more strategy groups which exist simultaneously are not found in the strategy group matched with each strategy family, the equipment information is determined not to be matched with the corresponding strategy group.

In order to enable the allocation of access gateways even when a policy group cannot be matched, the following processing needs to be performed:

step 1, GMS creates a default access gateway group and one or more access gateways, sets the initial state of the created one or more access gateways as off-line and the load as 0, configures the address of the access gateway, and adds the created one or more access gateways into the default access gateway group;

step 2, the GMS configures a default strategy group to the default access gateway group, wherein the default strategy group does not contain any strategy;

step 3, the GMS receives the load information reported by one or more access gateways, and updates the online state and the load information of the corresponding access gateway in the default access gateway group according to the reported load information;

step 4, when the device information can not be matched with the corresponding strategy group, the GMS matches the device information with a default strategy group and determines a default access gateway group corresponding to the default strategy group;

and 5, the GMS allocates the access gateway which is online and has the lowest load in the default access gateway group to the equipment according to the online state and the load information of each access gateway in the default access gateway group.

The above technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 2 is a signaling flow chart of an access gateway allocation method according to an embodiment of the present invention, and as shown in fig. 2, the method specifically includes the following processing:

step 201, the access gateway reports the load condition of the access gateway to the GMS at regular time;

step 202, the GMS determines that the report is not overtime, and sets the state of the access gateway to be online;

step 203, the GMS regularly detects the state of the access gateway and sets the access gateway which does not report the load after overtime as offline;

step 204, the equipment sends a request for obtaining the access gateway address to the GMS, wherein the request carries equipment information;

step 205, the GMS performs policy matching according to the device information to obtain a matched policy group, obtains an access gateway group corresponding to the policy group, determines an access gateway with the minimum load in the group, and sends an access gateway address obtaining response to the device, where the response message carries address information of the access gateway with the minimum load

And step 206, the equipment connects the allocated access gateway through the TCP according to the access gateway address sent by the GMS.

The above-described process flow will be described below by way of example.

First, data table structure and initialization

In the embodiment of the present invention, the GMS needs to persistently store access gateway and policy related data, and needs to use a database, a structure of the database table is shown in fig. 3, where the database table in the database specifically includes: a relationship table (policy group-policy), a policy table, a policy group table, a policy type table (data is not modifiable), a relationship table (policy group-policy group), a policy group table, a relationship table (policy group-access gateway table), an access gateway group table, a relationship table (access network group-access gateway), and an access gateway table, where specific parameters in each table are as shown in fig. 3.

After the database is created, the data tables need to be initialized, and some default data are created:

1. creating a default Access Gateway Group (AGGD) for distributing access gateways when not matched with any configured policy;

2. establishing an access gateway AGD1 and an AGD2, setting the initial state as off-line and the load as 0, and configuring an access gateway address (after the access gateway reports the load, the state can be updated to be on-line);

3. adding the access gateways AGD1, AGD2 to the access gateway group AGGD;

4. configuring a default Policy Group (PGD) to a default Access Gateway Group (AGGD); the default strategy group PGD does not contain any strategy or allows any strategy, and is only used when the strategy is not matched with any strategy group;

the relevant data table after the database initialization is completed is shown in fig. 4.

Second, configuration process

GMSs typically require the configuration of three parts:

1. configuring an access gateway group and an access gateway;

2. strategy group and strategy configuration;

3. and configuring the strategy group to the access gateway group.

Fig. 5 is a schematic diagram of a GMS configuration policy group and an access network group according to an embodiment of the present invention, and each configuration process is described below.

1. Newly establishing access gateway group and adding access gateway

The specific process is as follows:

(1) establishing an access gateway group AGG 1;

(2) newly building access gateways AG1, AG2 and AG3, setting the initial state as off-line, the load as 0, and configuring the access gateway address (after the access gateway reports the load, the state can be updated as on-line);

(3) the access gateways AG1, AG2, AG3 are added to the access gateway group AGG 1.

The relevant data table after configuration is shown in fig. 6.

2-1, creating new strategy group and creating strategy family

The specific process is as follows:

(1) newly building a policy group PG 1;

(2) according to all policy types in the "policy type table", creating policy families PF1_1, PF1_2, PF1_3, PF1_4 and PF1_5 corresponding to each policy type for the policy group PG 1;

(1) creating strategies P3 and P5 in a strategy table B corresponding to the strategy type PT 2;

(2) finding out a strategy family (PF1_2) of the strategy group PG1 corresponding to the strategy type PT2 according to the conditions of the right graph;

(3) the policies P3, P5 are added to the policy family PF1_2, respectively, according to the following rules:

(4) if the policy family has a default policy PD, then the default policy PD is modified to the policy ID to be added (e.g., P3);

(5) if the policy family has no default policy PD, adding a policy (such as P5) to the policy family;

the relevant data table after configuration is shown in fig. 8.

Adding other strategies and adding the strategies into the strategy group, wherein the flow is as follows:

(1) creating strategies P1, P3 and P4 in a strategy table C corresponding to the strategy type PT3 and adding the strategies P1, P3 and P4 into a strategy group PG1 in the same PT2 strategy flow;

(2) creating strategies P1, P3 and P4 in a strategy table E corresponding to the strategy type PT5 and adding the strategies P1, P3 and P4 into a strategy group PG1 in the same PT2 strategy flow;

the relevant data table after configuration is shown in fig. 9.

3. Configuring policy groups onto access gateway groups

After the above policy related configuration, all policies configured by policy group PG1 are shown in fig. 10. Configuring a policy group PG1 onto an access gateway group AGG 1; it should be noted that, in the embodiment of the present invention, one policy group may be configured to only one access gateway group, and one access gateway group may configure multiple policy groups at the same time; the relevant data table after configuration is shown in fig. 11.

Third, distribution process

Fig. 12 is a schematic diagram of a GMS access gateway according to an embodiment of the present invention, and as shown in fig. 12, when an access gateway is allocated, the method specifically includes the following processing:

step 1, respectively performing strategy matching according to information carried in the equipment request;

step 2, respectively carrying out strategy family matching according to the matched strategies;

step 3, according to the matched strategy family, matching the strategy group after summarizing;

step 4, selecting one with the highest priority from all the matched strategy groups;

step 5, searching the configured access gateway group according to the finally selected strategy group;

step 6, dividing the access gateways from the access gateway group according to information such as server load and the like;

the access gateway assignment procedure is explained in detail below.

The processing flow of the step 1 is as follows:

it is assumed that the device information carried in a device request includes: field B, field C, field E;

1. according to the policy type table, the field B needs to be matched with the rule from the policy table B, and the policy P5 is assumed to be matched;

2. according to the policy type table, the field C needs to be matched with the rule from the policy table C, assuming that the policy P1 is matched;

3. according to the strategy type table, the field E needs to be subjected to rule matching from the strategy table E, and the strategies P4 and P9 are supposed to be matched;

it should be noted that, if there is a field that is not matched with any policy in the device request field, the field may be skipped directly; a field may match multiple policies simultaneously;

the relevant data table after completion of matching is shown in fig. 13.

The processing flow of the step 2 is as follows:

1. as shown in fig. 14, a piece of "policy family matching data" is generated for matching all the matched policies with all the policy types, and is used for policy family matching. Supplementing a default policy PD for policy types not present in the data;

2. as shown in fig. 15, the first piece of data is taken from the "policy family matching data", and the policy family is queried according to the query conditions in fig. 15 (taking PT5 as an example, the policy families PF1_5 and PF2_5 are queried);

the relevant data table after completion of matching is shown in fig. 16.

3. And matching the strategy families corresponding to all other data in the strategy family matching data according to the same query logic.

It should be noted that, if any piece of data in the "policy family matching data" is not matched to the policy family, the access gateway is directly allocated by using the default policy group PGD; a policy family matching data may match multiple policy families simultaneously.

The relevant data table after completion of matching is shown in fig. 17.

The processing flow of the step 3 is as follows:

1. as shown in fig. 18, one policy family data is taken from the "policy family matching result", and a plurality of policy groups may be found at the same time (exemplified by PF1_5, PF2_5) according to the query condition in the following figure;

2. inquiring the strategy groups corresponding to all other strategy family data according to the same logic;

it should be noted that, if any piece of policy family data does not query a policy group, the access gateway is directly allocated by using the default policy group PGD.

The relevant data table after completion of matching is shown in fig. 19.

The processing flow of the step 4 is as follows:

1. searching for a policy group (PG1) for which each policy group data exists simultaneously;

2. there may be more than one policy group existing at the same time, and the highest priority (lower value and higher priority) is selected from the policy groups for access gateway allocation.

It should be noted that, if there is no policy group existing in each policy group data at the same time, the access gateway is directly allocated by using the default policy group PGD.

The relevant data table after completion of matching is shown in fig. 20.

From this point on, the policy-related matching is over, and there is one and only one policy group (configuration test policy group or default policy group PGD).

As shown in fig. 21 and fig. 22, a policy group configures a policy of a certain type, but the device request information may or may not carry a field corresponding to the policy type, and if the policy group is matched, the following conditions need to be satisfied:

the first condition is as follows: once a certain type of policy is configured in the policy group, the device requests a corresponding field of information, and the information is matched with at least one of the type of policy possibly;

and a second condition: policy group if the policy type corresponding to a field in the device request information does not configure any policy, the field may be considered a default match for the policy group.

The processing flow of the step 5 is as follows:

as shown in fig. 23, according to the query condition in fig. 23, the access gateway group AGG1 configured by the policy group PG1 is queried (since one policy group can only be configured to one access gateway group, only one access gateway group is queried). The relevant data table after completion of matching is shown in fig. 24.

The processing flow of step 6 is as follows:

as shown in fig. 25, according to the query condition in fig. 25, the access gateway AG3 that is online and lowest in load in the access gateway group AGG 1; the relevant data table after completion of matching is shown in fig. 26.

From now on, the whole procedure of assigning an access gateway to the device is completed, and the GMS may return the address of the assigned access gateway AG3 to the device.

In summary, with the aid of the technical solutions of the embodiments of the present invention, the problems that the load condition of the server cannot be identified and the server to which the device is to be connected cannot be grouped and managed when accessing the server of the internet of things in the prior art are solved, a specific device can be designated and connected to a specific group of access gateways with the same function according to the policy and the relevant configuration of the access gateways, and the device is designated and connected to the access gateway with the lowest load according to the load of the actual access gateway, so that the load of the system is more balanced.
