Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
As shown in fig. 1, the process for setting the BDT transmission policy includes the following steps:
step 101, a Service Capability Server (SCS)/an Application Server (AS) sends a BDT request to a Service Capability Exposure Function (SCEF);
step 102, the SCEF performs authorization and authentication on the request;
step 103, the SCEF negotiates a future BDT process with the PCRF (Policy and Charging Rules Function), triggers the PCRF to execute a PCC (Policy and Charging Control) process, and provides a possible BDT transmission Policy to the SCEF;
step 104, the SCEF returns a BDT response to the SCS/AS, the response including possible BDT transmission strategies;
step 105, if there is more than one possible BDT transmission strategy, the SCS/AS selects one of them and informs the SCEF;
step 106, the SCEF confirms the BDT transmission strategy selected by the SCS/AS;
step 107, the SCEF continues to negotiate the BDT transmission policy with the PCRF and stores the BDT transmission policy selected by the SCS/AS in the SPR (Subscription Profile Repository, user attribute storage);
in step 108, the SCS/AS notifies the PCRF, PCEF (Policy and Charging Enforcement Function), SPR to perform PCC procedure and implement BDT transmission Policy for the node at a later time point.
Step 108 is that the service/application entity notifies the 3GPP network to load the policy for using configuration in the set time window, how the service/application entity of the external system based on the resource architecture mode requests the 3GPP network to load and execute the configured BDT transmission policy, and monitors the transmission process thereof, which does not belong to the scope of 3GPP, and is not solved in the prior art.
The embodiment of the invention is realized IN a resource-based oneM2M system architecture based on oneM2M standard organization, and an Internet of things functional entity (including AE/CSE (application entity/common service entity)) initiates bottom layer network transmission based on a BDT transmission strategy through IN-CSE (Internet of things platform of oneM 2M).
Example one
As shown in fig. 2, a method for executing a transmission policy according to a first embodiment of the present invention includes the following steps:
step 201, an internet of things functional entity informs a target node monitored by using a BDT transmission strategy through an internet of things platform IN-CSE according to the BDT transmission strategy configured IN an underlying network, so that the underlying network monitors data transmission of the target node by using the BDT transmission strategy;
the functional entity of the internet of things is an application entity AE of the internet of things or a common service entity CSE of the internet of things.
The Internet of things functional entity is an initiator of the BDT transmission strategy configured IN the underlying network, the Internet of things functional entity initiates and completes the configuration of the BDT transmission strategy by creating the BDT resource IN the IN-CSE, and the Internet of things functional entity inquires the BDT resource through a standard interface provided by the IN-CSE to determine the BDT transmission strategy configured by the BDT resource and obtains the contents such as the BDT transmission strategy configured by the BDT resource.
The embodiment of the invention provides a unified operation mode, which is more favorable for opening the capability of loading and executing the configured BDT transmission strategy of the 3GPP network to various external system functional entities, and the 3GPP network is operated through the IN-CSE under the condition that the external functional entities do not support a 3GPP standard interface. IN the embodiment of the invention, the IN-CSE informs the 3GPP underlying network to transmit data by using the BDT transmission strategy, so that the 3GPP underlying network can know that a service/application entity of an external system based on a resource architecture mode expects the 3GPP underlying network to monitor the transmission data of a target node by using the BDT transmission strategy, thereby filling the blank of the prior art.
The underlay network may include PCEF, SPR, and PCRF. The target Node may be an ADN (Application specific Node), or an ASN (Application Service Node), or an MN (Middle Node).
IN an alternative scheme, the internet of things functional entity sends a message carrying parameters using the BDT transmission strategy to the IN-CSE, so that the IN-CSE knows that the internet of things functional entity requests the underlying network to use the BDT transmission strategy, and further informs the underlying network of a target node monitored by using the BDT transmission strategy.
IN an alternative, the functional entity of the internet of things sends a request message for creating or updating a BDTList (BDT list) attribute of a BDT resource to the IN-CSE, and further notifies the underlying network of a target node monitored by using the BDT transmission policy, that is, when the functional entity of the internet of things is instructed to perform data interaction with the target node, the underlying network executes the BDT transmission policy.
And the BDTList attribute for creating or updating the BDT resource indicates the target node identification monitored by using the BDT transmission strategy.
The Internet of things functional entity sends a request message for creating or updating the BDTList attribute of the BDT resource to the IN-CSE, wherein the request message is contained IN the message for creating the BDT resource, or the request message is used for creating the BDTList attribute IN the existing BDT resource, or the request message is used for updating the BDTList attribute IN the existing BDT resource.
The two schemes are based on the establishment or the update of resources in a resource mode, and carry parameters in the operation message of the resources, so that the operation of a service/application entity of an external system on the use of the 3GPP underlying network capability is simplified, and the operation efficiency is improved.
Example two
As shown in fig. 3, the method for executing a transmission policy according to the second embodiment of the present invention includes the following steps:
step 301, an IN-CSE receives a message sent by an internet of things functional entity, where the message is used to notify the underlying network to monitor data transmission of a target node by using the BDT transmission policy, and the internet of things functional entity is AE or CSE;
and 302, the IN-CSE acquires the target node monitored by using the BDT transmission strategy, and transmits BDT parameters to the underlying network to trigger a strategy and charging control (PCC) process, so that the underlying network executes the BDT transmission strategy when the functional entity of the Internet of things performs data interaction with the target node. The IN-CSE transmits the BDT parameters to the underlying network according to a standard interface provided by the underlying network.
The embodiment of the invention provides a unified operation mode, which is more favorable for opening the capability of loading and executing the configured BDT transmission strategy of the 3GPP network to various external system functional entities, and the 3GPP network is operated through the IN-CSE under the condition that the external functional entities do not support a 3GPP standard interface. IN the embodiment of the invention, the IN-CSE informs the 3GPP underlying network to transmit data by using the BDT transmission strategy, so that the 3GPP underlying network can know that a service/application entity of an external system based on a resource architecture mode expects the 3GPP underlying network to monitor the transmission data of a target node by using the BDT transmission strategy, thereby filling the blank of the prior art.
IN an alternative, a message sent by the internet of things functional entity carries a parameter using a BDT transmission policy, and the IN-CSE acquires a target node monitored by using the BDT transmission policy according to the parameter using the BDT transmission policy.
The target node used by the BDT transmission strategy is a receiver in the sending message.
IN an alternative, the message sent by the internet of things functional entity is a request message for creating or updating a BDTList attribute of a related BDT resource, and the IN-CSE learns the target node monitored by using the BDT transmission policy according to the request message, and accordingly creates or updates the BDTList attribute of the BDT resource.
Wherein the BDTList attribute represents an identification of the target node.
The BDT parameters transmitted by the IN-CSE to the underlying network may include one or more combinations of the following parameters: the identification or address of a target node of the data transmission of the functional entity of the Internet of things, the reference identification of the BDT transmission strategy and the identification of the functional entity of the Internet of things.
And the IN-CSE acquires the reference identifier for identifying the BDT transmission strategy according to the BDT resource where the created or updated BDTList attribute is located.
The target node identifier or address is the value of the BDTList attribute of the BDT resource IN the request message, or the IN-CSE maps to the IP address or other identifier of the target node through the value of the BDTList attribute of the BDT resource.
The two schemes are based on the establishment or the update of resources IN a resource mode, parameters are carried IN the operation message of the resources, and the IN-CSE can perform corresponding operation according to the received message, so that the operation efficiency is improved.
As shown in fig. 4, the present invention is a schematic diagram of BDT transmission between AE/CSE and ADN (Application Dedicated Node)/ASN (Application Service Node)/MN (Middle Node) by creating or updating BDT resource BDTList attribute in oneM2M system based on oneM2M system interacting with 3GPP network.
The AE/CSE creates BDT resources on the IN-CSE, namely the configuration of the BDT transmission strategy IN the 3GPP is completed, and the AE/CSE requests the 3GPP to adopt the BDT transmission strategy to the ADN/ASN/MN node. The BDTList attribute may be created at the same time the BDT resource is created, then the AE/CSE proceeds directly to step 402.
Step 401, the AE/CSE sends a request message for creating or updating the BDTList attribute of the BDT resource to the IN-CSE according to the oneM2M standard message format, which indicates that the AE/CSE expects the target node identifier of the 3GPP network to transmit data by using the BDT transmission policy;
step 402, the IN-CSE receives a request message for creating or updating the BDTList attribute of the BDT resource, authenticates that the AE/CSE has the authority to create or update the BDTList attribute of the BDT resource, and obtains the value of requesting to create a new BDTList attribute or update the existing BDTList attribute under the BDT resource according to the information carried by the request message, wherein the BDTList attribute value is the identifier of a target node (ADN/ASN/MN) which the AE/CSE expects a 3GPP network to use a BDT transmission strategy, and the identifier can be a node URL, an external network identifier, an identifier of a group resource and the like; that is, when AE/CSE hopes to perform data interaction with a target node, a BDT transmission strategy is executed on the target node by a 3GPP network
Step 403, the IN-CSE sends a message to the SCEF, where the message is used to request a PCC process of the 3GPP, and request the 3GPP to execute a BDT transmission policy for data interaction between the AE/CSE and the ADN/ASN/MN, where the message includes an identifier of the initiator AE/CSE, a referreneid of the AE/CSE configured with the BDT transmission policy, an IP address of a target node (ADN/ASN/MN), and so on;
the SCEF may be deployed in the underlying network by an operator, or may be deployed outside the underlying network by a third party.
Step 404, the SECF transmits the service information to the relevant network element of the 3GPP through the Rx interface defined by the 3GPP, triggers the PCC process, creates the relevant session, binds the relevant session and the IP-CAN bearer, and the relevant 3GPP network element loads the BDT transmission strategy corresponding to the referrence ID for executing the BDT transmission strategy in the subsequent data interaction between the AE/CSE and the ADN/ASN/MN.
Step 405, the underlying network completes the PCC process, and after providing the BDT transmission policy to the 3GPP network element for BDT transmission policy control, the SCEF returns a success message to the IN-CSE, indicating that the 3GPP network adopts the BDT transmission policy for data interaction between the AE/CSE and the ADN/ASN/MN.
IN step 406, the IN-CSE completes the BDTList attribute requesting to create or update the BDT resource and returns a resource creation or update success message.
Step 407, the AE/CSE sends the service data to the ADN/ASN/MN according to the interface and message flow defined by oneM2M, and the 3GPP gateway performs related data transmission monitoring according to the BDT transmission policy that has been loaded before.
As shown in fig. 5, a schematic diagram of the oneM 2M-based system interacting with a 3GPP network according to the application example of the present invention, parsing a message thereof through the oneM2M system, automatically triggering and requesting the 3GPP network to load a BDT transmission policy, and enabling the 3GPP network to adopt the BDT transmission policy for data transmission between AE/CSE and ADN/ASN/MN.
The AE/CSE creates BDT resources IN the IN-CSE, namely the configuration of the BDT transmission strategy IN the 3GPP is completed, and when the time window IN the BDT transmission strategy is met, the AE/CSE requests the 3GPP network to adopt the BDT transmission strategy for the data transmission of the AE/CSE and the ADN/ASN/MN node.
Step 501, the AE/CSE sends a request message for operating the remote ADN/ASN/MN to the IN-CSE, where the message includes, IN addition to the message parameters defined by oneM2M, a newly added BDT parameter to extend the existing message parameters, which indicates that the 3GPP network is expected to adopt a BDT transmission policy for data interaction between the AE/CSE and the ADN/ASN/MN.
Step 502, the IN-CSE receives the message sent IN step 501, learns the content of the parameters IN the partial message, the originator (from) of the message is AE/CSE, the destination (to) of the message is ADN/ASN/MN, the message is transmitted by BDT transmission policy, and the IN-CSE learns and confirms that the originator has configured the relevant BDT transmission policy according to the originator of the message; if no BDT transmission strategy is configured, the IN-CSE will refuse to send to the message, returning an error to the AE/CSE.
Step 503, the IN-CSE sends a message to the SCEF, where the message is used to request a PCC process of the 3GPP, and request the 3GPP to execute a BDT transmission policy for data interaction between the AE/CSE and the ADN/ASN/MN, where the message includes an identifier of the initiator AE/CSE, a referrenid of the AE/CSE configured with the BDT transmission policy, an IP address of the target node (ADN/ASN/MN), and so on;
step 504, the SECF transmits the service information to the relevant network element of the 3GPP through the Rx interface defined by the 3GPP, triggers the PCC process, creates the relevant session, binds the relevant session and the IP-CAN bearer, and the relevant 3GPP network element loads the BDT transmission strategy corresponding to the referrence ID for executing the BDT transmission strategy in the subsequent data interaction between the AE/CSE and the ADN/ASN/MN.
And 505, after the base layer network completes the PCC process and provides the BDT transmission policy to the 3GPP network element for BDT transmission policy control, the SCEF returns a success message to the IN-CSE, which indicates that the 3GPP network adopts the BDT transmission policy for data interaction between the AE/CSE and the ADN/ASN/MN.
IN step 506, the IN-CSE sends the data sent by the AE/CSE to the ADN/ASN/MN according to the interface and message flow defined by oneM2M, and the 3GPP gateway performs related data transmission monitoring according to the BDT transmission policy that has been loaded previously.
