Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a method for realizing network capacity openness, which is applied to a network capacity openness platform. The specific flow is shown in figure 1.
102, applying for an internal group identifier for a user group identifier corresponding to the identity information of the UE, and marking the user group identifier as an available state of the internal group identifier after the application is successful; the user group identifier corresponding to the identity information of the UE is configured by the network capability open platform or configured by the UE and carried in the subscription information.
And 103, calculating the routing information from the UE to the target network according to the effective area of the target network, and associating the routing information with the user group identifier.
In the prior art, from the NEF equipment standard in TS29.522, when data transmission is performed in a 5G network environment, it is necessary that a UE carries a user identifier, preferred routing information, and an effective area range in a request. Once the effective area and the routing information are changed by the NEF terminal, new routing information and effective area need to be fed back to all the UE terminals; meanwhile, if the internal group identifier corresponding to the user group identifier is not available, the result that the traffic guidance instruction cannot be executed needs to be returned to all the UE terminals to perform new traffic guidance, and the overhead of the data interaction process is high. The purpose of unfinished data transmission also causes the occupation and waste of transmission resources.
The implementation mode of the invention is mainly executed by a network capability open platform, is used for realizing the flow guiding process in the UE end and the NEF network element, and can be divided into the preparation and the execution of the flow guiding process. After receiving the subscription information sent by the UE, the network capacity open platform executes the information management function and acquires the preparation information of the flow guide process; the available state of the internal group identifier corresponding to the effective area, the routing information and the user group identifier is included; and after receiving a flow guiding instruction sent by the UE, realizing the flow guiding process according to the preparation information of the flow guiding process. The first embodiment is mainly a preparatory process.
In step 101, the effective area of the target network sent by the UE refers to an effective area indicated by a physical address of an edge server included in the target network. In one example, the effective area represented by the physical address of the edge server may be a multi-level drop-down list, and the effective area is an area from coarse granularity to fine granularity, such as a residential district, a company park, and the like, for the user to select and control, so that the selection of the target network is more in line with the actual situation, and the user experience is improved.
In addition, the subscription information also includes whether notification is needed after the status of the traffic guidance process is updated.
In one example, before step 102 is executed, the method further includes: and auditing the security authentication information carried in the subscription information and passing the auditing. For example, the security information may be enterprise qualification, record. Through the verification of the subscription information, the hidden danger in the information transmission process can be reduced, and the information safety of users and operators is guaranteed.
In step 102, an internal group identifier is applied for a user group identifier corresponding to the identity information of the UE, the internal group identifier is defaulted to an unavailable state, after the application is successful, the user group identifier is marked as an available state of the internal group identifier, and different state modification modes are provided according to an operator policy. In one example, the network capability openness platform applies for creating an internal group identifier for the user group identifier to a network element of another management group identifier, such as UDM, and when a successful response of creating the internal group identifier is obtained from the network element of the management group identifier, the operation platform modifies an available state of the internal group identifier, or an operator modifies an available state of the internal group identifier. The available state of the internal group identifier is detected before the user group identifier reaches the NEF network element, a selection basis is provided for information transmission, multiple data transmission is effectively reduced, and the maintenance investment in the process is reduced.
In step 103, converting the physical address of the edge server into the location identifier of the edge server, and obtaining an effective area represented by the location identifier of the edge server; and obtaining the routing information of the UE according to the effective area represented by the position identifier of the edge server. The network capability open platform obtains the location identifiers related to the UE location management one by one from external equipment or locally through modes such as inquiry and the like, and finally converts the physical addresses into the location identifiers. In one example, the location identifier may be a location identifier related to UE location management, such as Cell ID and/or tai (tracking Area ID) of a Cell, according to an actual policy of an operator.
In one example, if an edge server with a saturation degree exceeding a threshold exists in an effective area of the target network, updating the effective area represented by the position identifier of the edge server; the updated effective area represented by the position identifier of the edge server does not comprise the position identifier of the edge server with the saturation degree exceeding a threshold value; and obtaining the routing information from the UE to the target network according to the updated effective area represented by the position identifier of the edge server. And the available state of the edge server is updated in time, the validity of a target address of data transmission is kept, and the information transmission efficiency is improved.
If the network capacity open platform cannot automatically calculate and obtain the routing information because the data is incomplete, the routing information filled into the edge server by an operator.
In addition, the subscription information also comprises preset routing information; and obtaining the routing information from the UE to the target network according to the preset routing information and the effective area represented by the position identifier of the edge server. The preferred route provides reference for route calculation, so that the finally obtained route information is more accurate.
The second embodiment of the present invention relates to a method for implementing network capability opening, and a specific flow is shown in fig. 2.
Step 201: receiving subscription information sent by User Equipment (UE); the subscription information includes identity information of the UE and an effective area of a target network of the UE.
Step 202: applying for an internal group identifier for a user group identifier corresponding to the identity information of the UE, and marking the user group identifier as an available state of the internal group identifier after the application is successful; the user group identifier corresponding to the identity information of the UE is configured by the network capability open platform or configured by the UE and carried in the subscription information.
Step 203: and calculating the routing information from the UE to the target network according to the effective area of the target network, and associating the routing information with the user group identification.
Step 204: receiving a flow guiding instruction sent by UE; the flow guiding instruction carries user group identification.
Step 205: if the use state of the internal group identifier is available, determining that an interface field to be sent to a network capability open network element NEF comprises a user group identifier, an effective area of a target network and routing information associated with the user group identifier; and if the use state of the internal group identifier is unavailable, determining that the interface field comprises identity information corresponding to the user group identifier, an effective area of the target network and routing information associated with the user group identifier.
Step 206: the interface field is sent to the NEF.
In step 204, the network capability openness platform performs steps 205 to 206 after receiving the traffic guidance instruction of the UE; the traffic steering instructions contain the user group identification in order to obtain routing information associated with the user group data.
During the execution of step 205, the interface field sent to NEF by the zone is determined according to the usage status of the internal group identifier corresponding to the user group identifier obtained in step 202. If the application of the internal group identifier corresponding to the user group identifier is successful, that is, the internal group identifier is available, the interface field contains the user group identifier. And if the internal group identifier corresponding to the user group identifier is not applied successfully, namely the internal group identifier is unavailable, the interface field contains the identity information corresponding to the user group identifier. The method avoids the situation that the NEF end feeds back flow guide execution failure information to the UE end, ends the process and does not finish the data transmission target result because the internal group identification is unavailable. Data invalid feedback is not needed, and normal data sending can be guaranteed, so that the data transmission efficiency is improved.
In an example, after the step 206 is executed, if the effective area of the target network has an edge server whose saturation level exceeds the threshold, the effective area of the target network is updated, and the updated effective area of the target network does not include the location identifier of the edge server whose saturation level exceeds the threshold; if the UE is using the routing information in the interface field, transmitting the user group identification or the identity information corresponding to the user group identification to the edge server of which the saturation degree before the change of the effective area exceeds the threshold value; prompting the UE whether to stop using the edge server with the saturation degree exceeding the threshold value, and transmitting the user group identification or the identity information corresponding to the user group identification instead of the route information generated by the updated effective area of the target network. The data transmission effectiveness in the flow guide execution process is improved.
The second embodiment of the present invention provides a network capability open platform, which manages subscription data sent by a UE, including applying for an internal group identifier for a user group identifier, and determining in advance whether the internal group identifier is available; and calculating the routing information from the UE to the target network according to the effective area of the target network in the subscription information, associating the routing information with the user group identification, and completing information preparation work before executing flow guidance. And after receiving the flow guiding instruction, the network capacity open platform determines an interface field to be sent to the NEF according to the available state of the internal group identifier in the information preparation stage, so that the data transmission is ensured to be realized certainly. The problem that in the prior art, the flow guiding process cannot be transmitted due to the fact that the internal group identification is unavailable is avoided, and the information interaction process at the stage is reduced. Meanwhile, the effective area and the routing information are located on the network capacity open platform, and after the change occurs in the flow guiding process, the effective area and the routing information are returned to the network capacity open platform for data management, so that the UE end is prevented from carrying out multiple data transmissions with the NEF end in order to keep synchronization with the effective area and the routing information in an operator, and the flow guiding efficiency is improved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
