DETAILED DESCRIPTION

[0045] The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

[0046] The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

[0047] It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

[0048] The embodiments herein achieve methods for facilitating continuous integration and continuous deployment (CI-CD) in Fifth Generation (5G) networks. The method includes sending, by an Operations, Administration and Maintenance (OAM) controller, a request to trigger test upgraded technique for a network function (NF) to a Network Slice Management Service (NSMS) consumer. The request includes a parameter indicated as part of a test network slice Information Object Class (IOC). The parameter includes test slice information, managed function information test duration, a pre-emption indicator, and a use prediction and procedures to be tested. Further, the method includes receiving, by the OAM controller, a trigger test response from the NSMS consumer based on the request to trigger test upgraded technique. Further, the method includes configuring, by the OAM controller, at least one user equipment (UE) with a test slice identifier based on the trigger test response.

[0049] Referring now to the drawings, and more particularly to FIGS. 1 through 12, where similar reference characters denote corresponding features consistently throughout the figures, there are shown at least one embodiment.

[0050] Based on the proposed method, the ability to test upgraded network nodes in a live network will increase the agility of 5G networks. The network slicing can be used to assist in live testing. A test slice can be created/deployed, consisting the upgraded network functions, for testing purpose. The basic principles of the live testing should be: [0051] 1. Test-slice creation with appropriate information e.g., test cases, test duration, target network nodes etc. [0052] 2. Automatic UE selection: The UE to be assigned to the test network slice can be selected minimizing the impact of testing; e.g., the UEs can be selected based on the location of the network nodes where the upgraded software is deployed. This can be based on the current load conditions of the Network nodes. UEs can also be selected based on the UE characteristics like UE mobility and UE capabilities like Dual connectivity. [0053] 3. Deployment location selection for the upgraded node: The location of the node can be selected minimizing the impact of testing; e.g., the location of the Networks nodes that needs to be upgraded and tested can be selected based on load conditions of the Network nodes at a given time. The location of the node can also be based on the availability of UEs for testing in a given location. [0054] 4. Feature testing: It should be possible to select a set of features, among the list of all features, to be tested. For example, if Network function next generation NodeB (gNB) centralized unit (CU) is upgraded with features X, Y, Z but feature Y has dependency on the next generation (NG) interface with 5G core (5GC). In this case, only feature X, Z should be tested till the 5GC is also upgraded with feature Y. [0055] 5. Drone UE: The test UE (operator controlled) can be created and deployed in the target location.

[0075] Based on the request to trigger test upgraded technique, the CI-CD controller (140) is configured to receive a trigger test response from the NSMS consumer (200). Based on the trigger test response, the CI-CD controller (140) configures the UE (500) with the test slice identifier. The UE (500) with the test slice identifier is configured based on based on the availability of radio and cloud resources, availability of the UE (500), and an operator defined restriction.

[0122] The FIG. 11, depicting overview (S1100), shows a high level flow of how network slices are created for testing in the network and in a UE (500). The grey shaded boxes indicate “New test slice for Upgraded components functioning in production environment for testing new features or bug fixes”.

[0123] In an example, a drone UE can be automatically deployed based on the trigger deployment of the drone UEs configured with the new test slices created to test the upgraded software in different geographical locations. Embodiments herein select the deployment location of the upgraded software for testing. The deployment location can be selected based on the availability of radio and cloud resources, the availability of the selected UEs (e.g., UEs 100a, 100b, 100c, and 100d) and operator defined restrictions.

[0124] FIG. 12 is a flowchart depicting a process of deploying a test network slice triggered by an OAM controller, according to an embodiment of the disclosure.

[0125] Referring to FIG. 12 depicting flowchart (S1200), at operation 1202, an upgrade for the node is initiated. The new software package for the node is provided. At operation 1204, the test network slice allocation procedures are triggered including requests to create the testNetworkSlice IOC instance.

[0126] Option 1 (Table 1 is to use the existing NetworkSlice IOC with new testSliceInfo):

TABLE-US-00001 <NetworkSlice> <testSliceInfo></testSliceInfo> <NetworkSliceSubnet> </NetworkSliceSubnet> </NetworkSlice>

[0127] Option 2 (Table 2 is to use new testNetworkSlice IOC):

TABLE-US-00002 <TestNetworkSlice> <testSliceInfo></testSliceInfo> <NetworkSliceSubnetRef> <ServiceProfileRef> <SliceProfileRef> </NetworkSlice>

[0128] The existing slice profile and service profile can be reused for creation of the test slices. The references of existing NetworkSlice and NetworkSliceSubnet IOC can be reused. The testSliceInfo and its parameters are new additions, required in the 3GPP TS 28.541 specifications.

[0129] At operation 1206, Network Slice allocation procedures according to 3GPP TS 28.531 are executed. At operation 1208, the instance of Network slice IOC with testSliceInfo or TestNetworkSlice IOC is created and activated. At operation 1210, the UEs (500) that are required for the testing (e.g., operator controlled drones) can be configured with these slice IDs. The UEs (500) selected for testing can be: [0130] 1. Based on UE capability (Carrier aggregation, Dual connectivity capability). [0131] 2. Based on UE characteristics (Based on User Mobility (which can be determined based on UemobilityLevel)). [0132] 3. Based on UE RRC State (which can be determined based on the UE history information stored with the operator).

[0133] If the UE with the above criteria does not exist or if there is an operator restriction not to use customer Ues, then Trigger deployment of the drone Ues configured with the new slices created to test the upgraded software in different geographical locations based on the testing location criteria.

[0134] Selection of deployment location of the test software in the field can be based on: [0135] a. the availability of radio and cloud resources; [0136] b. the availability of UE selected; and [0137] c. operator defined restrictions.

[0138] At operation 1212, if further upgrade of any managed element is required or any modification of the TestNetworkSlice IOC instance is required, Network slicing modification procedures can be triggered, according to 3GPP TS 28.531. Additional Managed element can be included with new software package and new features. Parameters like coverageArea, maxNumberofConns, kPlMonitoring can be modified based on the test configuration changes, UE selection and deployment location updates.
