Background technique

With the development of the Internet of Things, hundreds of millions of terminal devices will be connected to the IoT platform to interact with applications, and one application can communicate with multiple devices at the same time. This is the network transmission capability, especially during peak hours. Transmission capacity is a test. The 3rd Generation Partnership Project (3GPP) provides a background data transfer (BDT) transmission method for the communication problem of massive terminal devices in the Internet of Things. In this transmission mode, by setting the network non-busy time window, the application and the device are provided with low-rate and fast communication, and at the same time, the pressure of the network during peak hours can be alleviated.

In the IoT architecture, the 3GPP network acts as the underlying network to interact with the IoT service layer to provide network information to the IoT services/applications on the IoT service layer. The IoT services/applications can be provided according to the 3GPP network based on their own needs. The transmission method is selected in order to optimize the transmission of information interaction between the Internet of Things service/application and the device.

Since the IoT scenario can be a public IoT platform that opens up multiple capabilities for services/applications, enabling multiple IoT capabilities, telecommunications capabilities, and third-party service capabilities to be reused, accelerating the deployment of IoT services/applications. The service/application can interact with the underlying network through the public IoT platform, and the 3GPP network as the underlying network does not fully consider the role and function of the IoT platform as a key node, and adopts the IoT system architecture of the public IoT platform. For example, based on the resource-based architecture, the way the IoT service/application interacts with the 3GPP network will be different, including the setting of parameters and the storage of policies. Currently, there is no corresponding solution.

The storing BDT transmission policy may include: a recommended time window, a charging rate in the time window, an aggregated max bitrate, and a reference ID corresponding to the transmission policy.

For newly defined resources you can have the following properties:

Expected time window, indicating the time window in which the application/service expects BDT transmission;

Each node data volume Volume Per Node, indicating the amount of data transmitted by each node in the time window in which the application/service expects BDT transmission;

Number of Nodes, indicating the total number of nodes that need to interact within the time window in which the application/service expects BDT transmission;

Request Ref ID, optionally identifying the BDT transmission policy configuration procedure/transaction, which is assigned by the AE/CSE;

Creator, indicating the creator of this resource, that is, the requester requesting the BDT transmission policy configuration process;

Possible traffic policies, indicating one or more possible BDT transmission policies provided by the underlying network according to the expected BDT transmission policy conditions of the application/service, including: agreed time window, charging rate, aggregated max bitrate; The attribute may also be represented by the sub-resource form of the newly defined resource, and the attribute value of the sub-resource includes: a modified time Window, a charging rate, an aggregated Max Bitrate, and optionally a traffic policy ID;

The selected traffic policy indicates the BDT transmission policy finally determined by the application/service from the possible BDT transmission policies, including: recommended time window, charging rate, aggregated max bitrate; when the above possible transmission policy attribute is sub When a resource is a resource, the resource is a link address or a transmission policy identifier that points to a child resource;

Reference identifier, provided by the underlying network, indicating the transmission strategy provided by the underlying network;

A traffic policy link. Optionally, when the finally selected transmission policy is stored in a defined resource in the oneM2M system, the selected transmission policy does not exist, and the attribute indicates the final selection of the storage. The link address of the resource of the BDT transport policy.

To reuse the defined resource [cmdh Nw Access Rule] in oneM2M system, you need to add attributes to the attributes of this resource, as follows:

The reference ID is provided by the underlying network and indicates the transmission policy provided by the underlying network. Optionally, if the attribute is not set separately, the reference ID value of the BDT transmission policy provided by the underlying network may be stored in [cmdhNw Access]. Rule] other conditions;

The creator, indicating the creator of this resource, is the AE-ID or CSE-ID, which is the requester requesting the BDT transmission policy configuration process.

At the same time, the IN-CSE learns that the AE/CSE request configures the BDT transmission policy according to the content of the request message, creates a resource, stores the condition parameter provided in the message in the attribute of the created resource, and provides the expected BDT transmission condition through the underlying network. The interface is transmitted to the network element of the underlying network to trigger the completion of the PCC (Policy Control and Accounting) process.

The IN-CSE then obtains one or more BDT transmissions of the AE/CSE that may be satisfied from the underlying network. The policy, and the reference identifier reference ID that identifies the transmission policy, stores the transmission policy and the reference ID in the resource, which is the resource that was previously requested to be created.

When there is only one BDT transmission policy that may satisfy the AE/CSE, the IN-CSE notifies the AE/CSE of the BDT transmission policy by returning the resource creation success message, and the IN-CSE confirms the BDT transmission policy provided by the underlying network, and completes The PCC process saves the transmission policy and the referenceID in the network element of the underlying network, so that the AE/CSE requests the underlying network to perform traffic monitoring and charging for the BDT transmission at the beginning of the time window.

When there are multiple BDT transmission policies that may satisfy the AE/CSE, the IN-CSE notifies the AE/CSE of the transmission policy by returning the resource creation success message. After the AE/CSE obtains multiple recommended transmission policies, select the corresponding ones. One as the final BDT transmission strategy. Then, the IN-CSE is notified of the transmission policy selected by the AE/CSE by updating the attribute value or the operation of the sub-resource in the previously created resource, and the IN-CSE passes the finalized BDT transmission policy and the reference ID through the interface provided by the underlying network. The network element transmitted to the underlying network triggers the PCC process, and saves the policy and the reference ID in the network element of the underlying network.

When the time window defined in the BDT transmission starts, the AE/CSE communicates with the remote entity, and the reference message is carried in the request message. After identifying the reference ID, the IN-CSE sends the message to the bottom layer through the interface provided by the underlying network. The network element of the network triggers the PCC process and implements BDT transmission.

Based on the resource architecture mode, this embodiment defines resources based on the oneM2M standard, defines a message transmission process, and based on IN-CSE, AE/CSE, and 3GPP network systems in oneM2M system, AE/CSE uses resource-based mode through IN-CSE and 3GPP networks. Interactively implement the BDT transmission policy configuration process.

Example 1

FIG. 5 is a schematic diagram of resources extended based on the existing resources of oneM2M according to the embodiment. As shown in FIG. 5, the extended resource structure of the network access rule [cmdhNwAccessRule] of oneM2M resource communication management and transmission processing includes, in addition to the In addition to the oneM2M common attribute, it can also include attribute management definition mgmt Definition, object identifier Object IDs, object path Object Paths, description description, target network target network, minimum request data amount min Req Volume, transmission waiting time speading Wait Time, compensation time back Of Parameters, other conditions other conditions, and management link mgmt Link. When the resource is used in the BDT transmission policy configuration and transmission process, on the basis of the foregoing resource structure, two attribute creator creator and reference identifier reference ID are added, and the creator may refer to the creator (identity identifier) of the resource. The ID may refer to an identifier assigned by the 3GPP network to the BDT transmission policy. In the configuration policy process, the other conditions of the other conditions can be used to store the parameters of the AE/CSE request BDT transmission policy, such as the expected time window, the amount of data of each node, and the number of nodes, and can also be used for BDT provided by the 3GPP network. The transmission policy (which may be multiple), the final BDT transmission policy selected by the AE/CSE, such as the recommended time window, the rate within the time window, and the maximum transmission rate; the attribute target network target Network may refer to the rule resource applicable. The underlying network can be represented by the UK Network-ID; the attribute description can be used to describe the resource, such as the BDT transmission policy used by the resource in an underlying network. Other attribute values of the resource are default, IN-CSE generation or AE/CSE assignment.

6 is a flowchart of a BDT transmission policy setting process based on the existing resources of oneM2M according to the embodiment. As shown in FIG. 6, the oneM2M system interacts with the 3GPP network, and the resource expansion in the oneM2M system is performed. The resource shown in Figure 5 implements the configuration of the BDT transmission policy in the 3GPP network.

The AE/CSE wants to set the BDT transmission policy, and then requests the applicable transmission strategy from the IN-CSE to the underlying network to select and complete the configuration on the underlying network.

In step 601, the AE/CSE sends a request to create a [cmdhNwAccessRule] resource to the AE/CSE under the parent resource <node> on the IN-CSE in accordance with the message format of the oneM2M standard to the IN-CSE.

Optionally, the request may include an AE/CSE allocation request Ref ID to identify the message or the BDT transmission policy configuration process.

The content parameter in the creation request contains the [cmdhNwAccessRule] resource structure, and assigns attribute values to some attributes, such as the value of the attribute creator AE/CSE-ID, the value of the attribute description is the BDT transmission policy, and the attribute target network is the UNetwork of the 3GPP network. ID, attribute other Conditions The value is an array of expected time windows, amount of data per node, and number of nodes.

In step 602, the IN-CSE receives the creation request from step 601, and the authentication AE/CSE has the authority to create the request resource, and the corresponding parent in the AE/CSE on the IN-CSE according to the parameter information carried in the request message. The resource is created under the <node> resource and assigned to some attributes. In addition, some attribute values can be default values (ie, system default values), such as min Req Volume, speading Wait Time, back Of Parameters, and so on.

In step 603, the IN-CSE learns that the AE/CSE sets the BDT transmission policy for the requesting 3GPP network according to the content of the parameter in the request message (the attribute description describes the resource, the network used by the rule specified by the attribute targetNetwork), and passes the 3GPP network through the 3GPP network. The provided Nt interface transmits the value of the other conditions and the creator to the PCRF network element of the 3GPP network, performs a PCC process to negotiate the BDT transmission policy, and the 3GPP network recommends the BDT transmission policy (including the recommended time window and the time window fee). Rate and maximum transfer rate) and a referenceID is returned to IN-CSE.

In step 604, the IN-CSE updates or assigns some attributes in the [cmdhNw Access Rule] resource according to the 3GPP network return information. The value of the attribute reference ID is the reference ID returned by the 3GPP network, and the attribute other Conditions may be in the original attribute value. Add BDT transmission strategy, which is an array of recommended time window, rate in time window and maximum transmission rate (when there are multiple recommended BDT transmission strategies, it can be an array list), or you can replace the recommended BDT transmission strategy array with the original one. There is an attribute value; if the [cmdhNwAccessRule] resource does not have an attribute reference ID, the reference ID returned by the 3GPP network may be stored in the attribute other Conditions along with the recommended BDT transmission policy.

In step 605, the IN-CSE notifies the AE/CSE of the recommended BDT transmission policy and the reference ID in the form of the successful request resource creation in the reply step 601.

In step 606, when the 3GPP network provides multiple BDT transmission policies, the AE/CSE selects one of the multiple BDT transmission policies according to its own requirements as the final determined BDT transmission strategy, and is previously in the IN-CSE. The created [cmdhNwAccessRule] resource sends an update request and updates the value of the attribute other Conditions.

In step 607, the IN-CSE receives the update request sent by the AE/CSE in step 606, completes the update operation of the attribute other Conditions, and can determine the final determined BDT transmission strategy in an array. The formula is added to the attribute value, or the final BDT transmission policy can be overwritten with the original value and the AE/CSE update operation is completed.

In step 608, the IN-CSE transmits the final determined BDT transmission policy, reference ID, and creator values to the 3GPP network through the Nt interface provided by the 3GPP network, performs a PCC process to continue the BDT transmission policy negotiation, and finally determines the BDT. The transmission policy and the reference ID are stored in the SPR network element to complete the setting of the BDT transmission policy in the 3GPP network.
