Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to a method and a device for distributing an address of an Internet of things terminal.
Background
The internet of things is that any object is connected with a network through information sensing equipment according to an agreed protocol, and the object performs information exchange and communication through an information transmission medium so as to realize functions of intelligent identification, positioning, tracking, supervision and the like.
When the terminal device accesses the internet of things, a corresponding IP address needs to be allocated to the terminal device. Currently, the following three address allocation methods are generally adopted:
the first distribution mode: and the SAEGW dynamically allocates the address mode, namely the SAEGW configures a corresponding IP address pool for the APN of the Internet of things, and when the user terminal is activated online, the SAEGW dynamically selects the IP address from the corresponding address pool and allocates the IP address to the user terminal.
And a second distribution mode: HSS/HLR static binding distribution mode, that is, HSS/HLR binds Internet of things card number and fixed IP address when making Internet of things card data. Therefore, when the internet of things card is activated online, the SAEGW allocates the internet of things card to a corresponding user terminal according to the IP address bound by the card.
A third distribution mode: the Radius server allocation method specifically includes two sub-allocation methods: one mode is that an internet of things card number and a certain fixed IP address are configured on Radius, and when the internet of things card is activated online, the SAEGW allocates the binding IP address fed back by the Radius to an activation request user (namely, still a static binding allocation mode); another way is that the Radius configures an IP address pool for an APN of an internet of things, and when a user of the internet of things is activated online, the Radius dynamically selects an IP address from the address pool and feeds the IP address back to the SAEGW, and finally allocates the IP address to the user (i.e., the Radius is still a way of dynamically allocating addresses).
However, the inventor finds that the following defects exist in the prior art in the implementation process: by adopting a static binding allocation mode, the binding configuration of the internet of things card and the fixed IP address needs to be completed on HSS or Radius in advance, so that a fixed relation correspondence table with huge data volume is generated, the resource expense is high, the maintenance cost is high, and the situations of relation binding conflict error, unbinding or address resource waste are easy to occur in the processes of recovering an old card, issuing a new card and the like; in addition, no matter a static binding allocation mode or a dynamic address allocation mode in the prior art is adopted, the flexibility is low, and different application scenes cannot be adapted.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
Fig. 1 is a schematic flowchart illustrating a method for allocating an address of an internet of things terminal according to an embodiment of the present invention. The method for allocating the internet of things terminal address provided by the embodiment may be executed by a device with computing capability, and the embodiment does not limit a specific type of the computing device.
As shown in fig. 1, the method includes:
step S110: and receiving an address allocation request and acquiring a user identifier corresponding to the address allocation request.
In the actual implementation process, the execution device of the method may perform information interaction with the SAEGW in the core network, and the SAEGW further sends the address allocation request initiated by the user terminal to the execution device of the method.
The address allocation request carries a user identifier corresponding to the request, where the user identifier is specifically an identifier capable of uniquely identifying a user terminal, and for example, the user terminal identifier may be an internet of things card number.
Step S120: judging whether the address associated information of the user identifier is found; if not, executing step S130; if yes, go to step S140.
Unlike the prior art, in the present embodiment, the allocation and management of the IP address are realized by the address association information including the timer. Specifically, each piece of address association information in this embodiment corresponds to a user identifier, and each piece of address association information at least includes three types of information, that is, a user identifier, an IP address associated with the user identifier, and corresponding timer information. Optionally, in order to facilitate centralized management of the address association information, and the like, the address association information in this embodiment further includes IP address use state information; wherein, the IP address using state information comprises: an active state and a dormant state. When the user is on-line, the IP address state in the corresponding address association information is an activated state, and when the user is off-line, the IP address state in the corresponding address association information is a dormant state.
Wherein, the timer information indicates the retention time of the association relationship between the user identifier and the corresponding IP address, and the survival state of the corresponding address association information can be controlled according to the timer information. Optionally, if the timer is in an overtime state, automatically deleting the corresponding address association information, and recovering the IP address in the corresponding address association information; if the timer is in the non-overtime state, the corresponding address association information is kept, and the locking state of the IP address is kept. That is to say, the survival status of the address associated information in this embodiment depends on the corresponding timer, and the timer is in a configurable status, so that the survival status of the address associated information can be flexibly controlled through the configuration of the timer, and then the flexible allocation of the IP address of the user terminal is realized.
In an optional implementation manner, in order to enrich an applicable scenario of the method and further improve flexibility of IP address allocation, the timer information in this embodiment specifically includes a survival type of the address association information, where the survival type includes at least one of the following types: a permanent type, a temporary type, and a specified duration type. When the survival type is a permanent type, the address association information is permanently alive; when the survival type is a temporary type, deleting the address associated information after the user is offline; and when the survival type is the specified duration type and the generation duration of the address associated information reaches the specified duration, deleting the address associated information.
In yet another optional implementation manner, the timer information described in this embodiment includes user-level timer information and/or APN-level timer information. Wherein the user-level timer information has a higher priority than the APN-level timer information.
Further optionally, in an implementation, after the user terminal initiates an address allocation request, the core network SAEGW receives the terminal address allocation request, and queries whether the address allocation request carries user-level timer information, and if so, sends the address allocation request carrying the user-level timer information to the method execution device; if not, sending an address allocation request carrying APN-level timer information to the execution equipment of the method; in another preferred embodiment, the configuration of the user-level timer information and/or APN-level timer may be implemented at the core network SAEGW, so that the core network SAEGW queries whether the user-level timer information corresponding to the terminal address allocation request is configured after receiving the terminal address allocation request, and if so, sends the user-level timer information and the address allocation request to the method execution device; if not, the APN level timer information corresponding to the terminal address allocation request and the address allocation request are sent to the method execution equipment.
Step S130: and allocating an IP address for the user terminal corresponding to the user identifier, and generating address association information of the user identifier according to the user identifier, the allocated IP address and the timer information carried by the address allocation request.
When the address association information of the user identifier is not found, an IP address can be selected, and the selected IP address is distributed to the user terminal corresponding to the user identifier. When the IP address is selected, if the address allocation request carries the specified IP address, allocating the specified IP address to the user terminal corresponding to the user identifier; and if the address allocation request does not carry the specified IP address, dynamically allocating the IP address for the user terminal corresponding to the user identifier. Optionally, in order to improve the allocation accuracy of the IP address, in the dynamic allocation process, the destination address pool is determined specifically according to the APN and/or number segment information corresponding to the user identifier; and further selecting an IP address from the target address pool, allocating the selected IP address to a user terminal corresponding to the user identifier, and then transmitting the allocated IP address to the user terminal through a core network SAEGW.
Further, according to the user identifier, the allocated IP address and the timer information carried by the address allocation request, address association information of the user identifier is generated. The generated address related information can be managed and stored in a centralized way. When the timer in the address associated information is in a timeout state, deleting the address associated information, then releasing the association relationship between the user identifier and the allocated IP address, and recycling the allocated IP address for allocation of other user terminals.
Optionally, the generated address association information may be centrally managed and stored. The IP address in the current occupied state can be quickly and accurately obtained through the centralized management and storage, so that a foundation is provided for quick and accurate allocation of subsequent IP addresses.
Further optionally, the present embodiment can change the generated address association information in a corresponding manner, thereby changing the association relationship between the user terminal and the allocated IP address, further implementing flexible allocation of the IP address, and meeting different application scenarios. In a specific change process, a change request for the address associated information may be received, and the address associated information may be changed according to the change request. The change request may be a change request for the entire piece of address association information (e.g., deleting a piece of address association information), or a change request for some piece of information in the address association information, such as a change request for an IP address in the address association information, or a change request for timer information in the address association information, or the like. In addition, the change request for the address association information may be triggered by a maintenance person who centrally manages the address association information, or may receive the address association information sent by the core network SAEGW, or the like.
Step S140: and allocating the IP address in the address association information to the user terminal corresponding to the user identification.
If the address association information of the user identifier is found, indicating that the association relationship between the user terminal corresponding to the user identifier in the address association information and the IP address in the address association information is still in a survival state, directly allocating the IP address in the address association information to the user terminal corresponding to the user identifier. In particular, the assigned IP address may be sent to the user terminal via the core network sae gw.
The following explains a specific implementation process of the internet of things terminal address allocation method in the embodiment by using a specific scenario example:
example 1
Application test scenario/security management scenario
In the existing application test scenario and/or security management and control scenario, it is usually necessary to fix IP addresses of some internet of things cards and configure corresponding fixed time limits, however, the requirement cannot be met by adopting the static IP address allocation or dynamic IP address allocation in the prior art, and by adopting the internet of things terminal address allocation method provided by this embodiment, the application scenario requirement can be met quickly, and the specific implementation process is as follows:
when sending an address allocation request, a user terminal that needs to perform IP address fixing carries corresponding configuration information, where the configuration information may include timer information, and the timer information specifies IP fixing time. Since the user terminal sends the address allocation request for the first time at this stage, in this embodiment, when the address allocation request forwarded by the core network SAEGW is received, the address association information of the internet of things card number (i.e., the user identifier) corresponding to the user terminal cannot be found, so that an IP address can be selected from the address pool of the APN and/or number segment information corresponding to the user identifier and allocated to the user terminal, and corresponding address association information is generated, and the generated address association information is shown in table 1, where one "120" in the timing information is specifically a rated association duration for which the user terminal "123456" and the IP address "x.x.x.1" have an association relationship, and the other "120" is a remaining duration of the association relationship at present. When the user terminal "123456" goes offline and goes online, if the remaining duration of the association is greater than or equal to 0 (i.e., the timer is in the non-overtime state), the address association information of the user terminal "123456" is not deleted, so that the IP address of "x.x.x.1" in table 1 is still allocated to the user terminal "123456"; if the association relation timer is in a timeout state, the address association information of the user terminal "123456" is deleted, and when the user is online again, and the corresponding address association information is not found, a new IP address is allocated to the user terminal again.
TABLE 1
| User identification | Address | State of use | Timer information |
| 123456 | x.x.x.1 | active | 120，120 |
Example two
Distribution mode change scenario
When the prior art is adopted to realize the change of the allocation mode (for example, a static allocation mode is changed into a dynamic allocation mode, and a user terminal with the changed allocation mode keeps using the original APN), the address allocation resource of the APN needs to be replanned on Radius, and the binding configuration of the changed number and the corresponding fixed IP is completed in advance. By adopting the method for allocating the internet of things terminal address provided by the embodiment, the change of the allocation mode can be quickly realized, and the specific implementation process is as follows:
the original allocation manner of the ue "123456" is a static allocation manner, and as shown in table 1, the ue "123456" may be allocated with an IP address "x.x.x.1"; if the allocation mode needs to be modified into a dynamic allocation mode, the generated address associated information of the user terminal "123456" may be deleted, or the timer information of the address associated information of the user terminal "123456" may be modified into "temporary", so as to quickly implement the change of the allocation mode.
Therefore, in the embodiment, address association information containing a timer is distributed for a user, the survival state of the address association information is determined through the timer information, and the address association relationship is deleted when the timer is in an overtime state, so that a huge relationship information table does not need to be maintained, the maintenance cost can be greatly reduced, and the system overhead is reduced; moreover, the switching of dynamic and static allocation modes can be quickly realized by modifying the timer information, and the flexible configuration of the IP address is realized, so that the method can be adapted to different application scenes and is suitable for large-scale application and implementation; in addition, in the process of recovering an old card, issuing a new card and the like, the situations of relation binding conflict error, unbinding or address resource waste are not easy to occur.
Example two
Fig. 2 is a functional structure diagram of a terminal address allocation device of the internet of things according to a second embodiment of the present invention. As shown in fig. 2, the apparatus includes: a receiving module 21, a judging module 22, a first allocating module 23 and a second allocating module 24.
The receiving module 21 is adapted to receive an address allocation request and obtain a user identifier corresponding to the address allocation request;

the first allocating module 23 is adapted to, if the address association information of the user identifier is found, allocate an IP address in the address association information to a user terminal corresponding to the user identifier;
the second allocating module 24 is adapted to allocate an IP address to the user terminal corresponding to the user identifier if the address association information of the user identifier is not found, and generate the address association information of the user identifier according to the user identifier, the allocated IP address and the timer information carried in the address allocation request.
Optionally, the controlling the survival status of the address association information according to the timer information further includes:
if the timer is in an overtime state, deleting the address associated information;
if the timer is in the non-overtime state, the address association information is reserved.
Optionally, the timer information further includes: the survival type of the address association information;

Optionally, the second allocating module is further adapted to: determining a target address pool according to the APN and/or number segment information corresponding to the user identification;
and selecting an IP address from the target address pool, and distributing the selected IP address to the user terminal corresponding to the user identifier.

Therefore, in the embodiment, address association information containing a timer is distributed for a user, the survival state of the address association information is determined through the timer information, and the address association relationship is deleted when the timer is in an overtime state, so that a huge relationship information table does not need to be maintained, the maintenance cost can be greatly reduced, and the system overhead is reduced; moreover, the switching of dynamic and static allocation modes can be quickly realized by modifying the timer information, and the flexible configuration of the IP address is realized, so that the method can be adapted to different application scenes, and is suitable for large-scale application and implementation.
