[0068] FIG. 1 illustrates an example communication environment in which example embodiments of the present disclosure can be implemented. Referring to FIG. 1, as an illustrative example without limitation, a simplified schematic illustration of a communication system (also referred to as computing and communications environment) 100 is provided. The communication system 100 (which may be a wireless system) includes a radio access network (RAN) 120. The RAN 120 may be a next generation (e.g., sixth generation (6G) or later) radio access network, or a legacy (e.g. 5G, 4G, 3G or 2nd generation (2G) ) radio access network. One or more communication electronic device (ED) 110a, 110b, 110c, 110d, 110e, 110f, 110g, 110h, 110i, 110j (generically referred to as ED110) may be interconnected to one another or connected to one or more network nodes (170a, 170b, generically referred to as 170) in the radio access network 120. A core network 130 may be a part of the communication system 100 and may be dependent or independent of the radio access technology used in the communication system 100. The communication system 100 may also comprise a public switched telephone network (PSTN) 140, the internet 150, and other networks 160.
[0069] In general, the communication system 100 enables multiple wireless or wired elements to communicate data and other content. The communication system 100 may provide content, such as voice, data, video, and / or text, via broadcast, multicast, groupcast, unicast, etc. And the communication system 100 may provide a wide range of communication services and applications (such as earth monitoring, remote sensing, passive sensing and positioning, navigation and tracking, autonomous delivery and mobility, etc. ) The services and / or applications may be mobile broadband (MBB) services, ultra-reliable low-latency communication (URLLC) services, or machine type communication (MTC) services.
[0070] The communication system 100 may operate by sharing resources, such as carrier spectrum bandwidth, between its constituent elements.
[0071] FIG. 2 illustrates another example communication environment in which example embodiments of the present disclosure can be implemented.
[0072] The communication system 100 may include a terrestrial communication system 120a / 120b and / or a non-terrestrial communication system 120c. The communication system 100 may provide a high degree of availability and robustness through a joint operation of a terrestrial communication system 120a / 120b and a non-terrestrial communication system 120c. For example, integrating a non-terrestrial communication system 120c (or components thereof) into a terrestrial communication system 120a / 120b can result in what may be considered a heterogeneous network comprising multiple layers. The heterogeneous network may achieve better overall performance through efficient multi-link joint operation, more flexible functionality sharing, and faster physical layer link switching between terrestrial networks and non-terrestrial networks.
[0073] The terrestrial communication system 120a / 120b and the non-terrestrial communication system 120c could be considered sub- systems of the communication system.
[0074] The communication system 100 may include ED 110a, 110b, 110c, 110d (generically referred to as ED 110) , and RAN 120a, 120b. In addition, the communication system 100 may also include a non-terrestrial communication network 120c. The communication system 100 may also include one or more of a core network 130, a public switched telephone network (PSTN) 140, the Internet 150, and other networks 160. The RANs 120a, 120b include respective RAN nodes such as base stations (BSs) 170a, 170b, which may be generically referred to as terrestrial transmit and receive points (T-TRPs) 170a, 170b (generically referred to as T-TRP 170) . In one implementation, the non-terrestrial communication network 120c includes a RAN node such as an access node (or base station) 172, which may be generically referred to as a non-terrestrial transmit and receive point (NT-TRP) 172. As may be surmised on the basis of similarity in reference numerals, the non-terrestrial communication network 120c may be considered to be a radio access network, with operational aspects in common with the RANs 120a, 120b. In another implementations, the non-terrestrial communication network 120c may include at least one non-terrestrial network (NTN) device and at least one corresponding terrestrial network device, wherein the at least one non-terrestrial network device works as a transport layer device and the at least one corresponding terrestrial network device works as a RAN node, which communicates with the ED 110 via the non-terrestrial network device. In addition, there may be a NTN gateway in the ground (i.e., referred as a terrestrial network device) also as a transport layer device to communication with both the NTN device, and the RAN node communicates with the ED 110 via the NTN device and the NTN gateway. In some embodiments, the NTN gateway and the RAN node may be located in the same device.
[0075] Any ED 110 may be alternatively or additionally configured to interface, access, or communicate with any T-TRP 170a, 170b and NT-TRP 172, the Internet 150, the core network 130, the PSTN 140, the other networks 160, or any combination of the preceding. In some examples, ED 110a may communicate an uplink (UL) and / or downlink (DL) transmission over a terrestrial air interface 190a with T-TRP 170a. In some examples, the EDs 110a, 110b, 110c, and 110d may also communicate directly with one another via one or more sidelink (SL) air interfaces 190b. In some examples, ED 110d may communicate an uplink and / or downlink transmission over a non-terrestrial air interface 190c with NT-TRP 172.
[0076] The air interfaces 190a and 190b may use similar communication technology, such as any suitable radio access technology. For example, the communication system 100 may implement one or more channel access methods, such as code division multiple access (CDMA) , space division multiple access (SDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or single-carrier FDMA (SC-FDMA, also known as discrete Fourier transform spread OFDMA, DFT-s-OFDMA) in the air interfaces 190a and 190b. The air interfaces 190a and 190b may utilize other higher dimension signal spaces, which may involve a combination of orthogonal and / or non-orthogonal dimensions.
[0077] The non-terrestrial air interface 190c can enable communication between the ED 110d and one or multiple NT-TRPs 172 via a wireless link or simply a link. For some examples, the link is a dedicated connection for unicast transmission, a connection for broadcast transmission, or a connection between a group of EDs 110 and one or multiple NT-TRPs 172 for multicast transmission.
[0078] The RANs 120a and 120b are in communication with the core network 130 to provide the EDs 110a 110b, and 110c with various services such as voice, data, and other services.

In some embodiments, the NT-TRP 172 implements physical layer processing, but does not implement higher layer functions such as functions at the medium access control (MAC) or radio link control (RLC) layer. As this is only an example, more generally, the NT-TRP 172 may implement higher layer functions in addition to physical layer processing.

[0119] Control and Management (C / M) layer 520 includes control and management services of the 6G System. They are developed and deployed by using slicing techniques and utilizing resource provided by infrastructure layer 510.6G services in Control and Management (C / M) layer are:
[0120] Resource Management (RM) as a Service 521 provides a capability of life-cycle management of a variety of slices and over-the-air resource assignment to wireless devices.
[0121] A 6G mission is defined as a service provided to customers by the 6G System. A mission can be a type of services which is provided by a single 6G XaaS service or a type of services that needs contributions from multiple XaaS services.
[0122] Mission Management (MM) as a Service 522 provides a capability to program provisioning of XaaS services at Service Layer to provide mission services.
[0123] Confederation Network (CONET) as a Service 525 provides a capability to enable multiple partners jointly provide 6G services. This capability is provided by confederation formation, mutual authentication, mutual authorization among partners and negotiation of agreement on recording and retracing of selected actions performed by partners, in order to assure a trustworthy environment of 6G System operations.
[0124] Service Provisioning Management (SPM) as a Service 523 provides a capability of control and management of 6G service access by customers and provisioning of requested services. The capability is provided by unified mutual authentication, authorization and policy, key management, QoS assurance and charging between any pair of XaaS service provider and customer. The customers include end-customers not only in physical world, but also digital representatives in digital world.
[0125] Connectivity Management (CM) as a Service 524 leverages 5G connectivity management functions, but with extension to include digital world.
[0126] Protocol as a Service 526 provides a capability to design service customized protocol stacks for identified interfaces.
[0127] The protocol stacks could be pre-defined for on-demand selection, or could be on-demand designed.
[0128] Network Security 527 as a Service provides a capability for owners of infrastructures to detect potential security risks of their infrastructures.
[0129] XaaS services in C / M Layer 520 support control and management of the 6G System itself and also provide support to verticals if requested. One example is that RM service can serve RAN for over-the-air resource management and can also provide service to a vertical for the vertical’s over-the-air resource allocation to its end-customers. The XaaS in C / M layer 520 can be deployed by using slicing technique.
[0130] Service Layer 530 includes 6G services which provide services to customers. In the 6G System conceptual structure:
[0131] AI service is denoted as NET4AI as a Service 531. Artificial Intelligence service provides AI capability to support a variety of AI applications.
[0132] Service of data collection, data sanitization, data analysis and data delivery are denoted as data analytics and manage (DAM) as a Service, this service provides a capability of lifecycle management of statistic data, including acquisition, de-privatization, analysis and delivery of data which are information statistic data from any types of sensors, devices, network functions, and etc.
[0133] Service of storage and sharing of data is denoted as NET4Data as a Service 532, this service provides a capability to trustworthily storage and share data under the control of owners of data and following recognized authorities’ regulations on control of identified data.
[0134] Service to provide digital world is denoted as NET4DW as a Service 535, Digital World service provides a capability to construct, control and manage digital world. Digital world is defined as digital realization of physical world.
[0135] 6G block chain service is denoted as NET4BC as a Service 534.6G connectivity service is denoted as NET4Con as a Service. This service provides a capability to support 6G block chain services.
[0136] Enhanced connectivity service, e.g., network for connectivity (NET4CON) as a service 536.
[0137] This service provides a capability to support exchange of messages and data among new 6G services.
[0138] All XaaS services at this Layer are developed and deployed by using resource provided in infrastructure and utilizing Network Function Virtualization and Slicing techniques. The capability of each of 6G services is provided by its control and management functions and service specific data process functions.
[0139] In addition to support 6G XaaS services at Service Layer, 6G System leverages 5G System for provisioning of vertical services. The difference between 6G XaaS services and other verticals are that a vertical is a pure customer which needs other XaaS services to enable its operation, while each of XaaS services provide their capabilities to 6G customers.
[0140] Any pair of XaaS services of the 6G System could also be mutual customer and provider of each other. Some of example are that an infrastructure owner provides its resource to XaaS services in Service Layer 530 and C / M Layer 520; RM services may need the capabilities provided by NET4AI 531, DAM 533 and NET4DW 535 for its resource management for vertical slicing; CONET service 525 and NET4Data service 532 may need the capability provided by NET4BC 534 for their operation.
[0141] The key concepts of 6G System includes:
[0142] - Define Basic XaaS Services by decoupling comprehensive types of services into basic XaaS services. A basic XaaS service provides unique capability to enable a specific type of service, such as NET4AI service 531, NET4DW service 535, DAM service 533, NET4Data service 532, Block chain service 534, mission management service 522, etc.
[0143] - Allow joint operation of the 6G System by multiple partners.

[0145] - Simplify 6G System architecture by categorizing basic control services and management services and combining them as basic XaaS services in Control and Management (C / M) Layer 520.
[0146] - Define C / M Plane of the 6G System which includes C / M functions in XaaS services and may include 5G CP (e.g., AMF) depending on implementation options.
[0147] - Define Basic Architecture Structure (BAS) which is a unified basic structure with minimized number of interfaces and is independent of types of infrastructures.
[0148] - Simplify standardization, development and deployment of the 6G System using the BAS concept, while supporting a variety of infrastructure deployment scenarios.

[0157] - Support future extension by adding new XaaS services with minimized impact on standardization and deployment, due to the introduced anonymous service provisioning concept implemented in trustworthy GWs in 6G C / M plane and in 6G data plane.
[0158] For illustrative purposes, specific example embodiments will now be explained in greater detail in conjunction with the figures and above mentioned system, core network, ED and TRP.
[0159] The embodiments set forth herein represent information sufficient to practice the claimed subject matter and illustrate ways of practicing such subject matter. Upon reading the following description in light of the accompanying figures, those of skill in the art will understand the concepts of the claimed subject matter and will recognize applications of these concepts not particularly addressed herein. It will be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
[0160] The present disclosure provides systems, apparatuses and methods for information processing (for example, mission templates which are also called mission slice templates) .
[0161] In the present disclosure, a mission is to achieve a designated goal, known as mission goal, which may include at least one of (1) providing PDU connectivity and optionally (2) providing data processing. When the mission goal includes providing data processing, the mission goal is associated with specific computational problem (s) , and providing data processing refers to solving the specific computational problem (s) . In this case, the mission includes one or multiple computing blocks (CBs) and is associated with a networking procedure among the CBs for solving the specific computational problem (s) . A CB within the mission corresponds to a defined computational step toward the mission goal (i.e., solving the specific computational problem (s) ) and may be supported by a service (for example, in the form of a task, a data network (DN) , or another mission) , accordingly, the CB is referred to as a task CB (corresponding to a service in the form of a task) , an external CB (corresponding to a service in the form of a data network) or a sub-mission CB (corresponding to another mission) . Mission management includes programming a mission, instantiating a mission and achieving a mission goal.
[0162] A mission slice is a logical network that provides specific capabilities and characteristics in networking and computing (including storage) for a mission. A CB within the mission corresponds to a subnet, referred to as CB subnet, of the mission slice. The CB subnet provides computing functionalities of achieving the corresponding computational step toward the mission goal. A mission slice instance incudes a set of network function instances and the required resources (e.g., computing, storage, and networking resources) and computing logic (e.g., in terms of parameter configuration) which form a deployed mission slice. A mission service is a service that provides achieving of a mission goal, a. k. a. executing of a mission, between a network entity (NE) , e.g., a UE or an AS, and a DN. A mission session refers to an association between an NE and a DN, providing a mission service with support from a mission slice instance.
[0163] Without ambiguity, mission and mission slice are used interchangeably for ease of presentation unless clarified; likewise, CB and CB subnet are used interchangeably. When a mission is instantiated, a mission slice instance is created for the mission. The mission slice instance is thus considered an instance of the mission. For each CB within the mission, the mission instance includes an instance of the CB. If the CB is a task CB, the CB instance is located in a XaaS service module (or, a service module for simplicity) supporting the task CB; if the CB is an external CB, the CB instance is located in the respective DN; if the CB is a sub-mission CB, the CB instance is an instance of a mission corresponding to the CB. The mission can have multiple instances. A CB instance may be shared by multiple mission instances when the CB instance is stateless. Likewise, a mission instance may be shared by (i.e., support) multiple applications when the mission instance is stateless. A mission instance is stateless if and only if the mission instance does not include stateful CB instances.
[0164] FIG. 6 illustrates an architecture for the mission management in this disclosure. As shown in FIG. 6, the architecture 600 includes a number of network functions: AF 610, MDR 615, MIR 620, MCF 625, MEF 630, SCF 635, TCF 640 and PSF 645. In some embodiments, any two or more of the network functions above may be integrated as one network function. For example, the MIR 620 and the MDR 615 are integrated. In the following, the network functions shown in FIG. 6 will be described.
[0165] AF (Application function) 610. The AF 610 can request to create / update a mission or remove a mission as described in this disclosure. For example, in the present disclosure, creating a mission refers to creating description information of the mission. The description information can be in any form, for example, in the form of mission template. The details relating to the mission template will be further described below. Likewise, updating a mission refers to update the description information of the mission, for example, updating at least one element in the mission template of the mission. And removing a mission refers to remove the description information of the mission, that is, the mission template of the mission. Nature of the AF is not limited. That is, any network entity can act as AF. Without ambiguity, AF and AF network entity are used interchangeably for ease of presentation unless clarified.
[0166] MDR (Mission data repository) 615. The MDR 615 stores mission templates. As described above, the mission template is a form of description information relating to a mission. The content of a mission template is described in the Table 1 as described below. The MDR receives the mission template from the MEF 630. The MEF 630 may receive part of the mission template from the AF 610, and part of the mission template from one or multiple SCFs. In some embodiments, the MDR 615 provides the mission specification in the mission template or the mission template to the MCF 625 according to the MCF’s request. The MDR 615 may further provide the mission intent in the mission template to the AF 610 via the MEF 630, e.g., according to a subscription or a request from the AF 610. Without ambiguity, MDR and MDR network entity are used interchangeably for ease of presentation unless clarified.
[0167] MIR (Mission instance repository) 620. The MIR 620 stores mission instance information. A mission instance information describes an instance of a mission. Without ambiguity, MIR and MIR network entity are used interchangeably for ease of presentation unless clarified.
[0168] MCF (Mission control function) 625. The MCF 625 controls and coordinates an execution of a mission over an instance of the mission, including starting, pausing, resuming, stopping, terminating the mission execution. The MCF 625 starts, pauses, resumes, stops or terminates the mission execution according to a request, e.g., from a device or an AF, or upon certain event, e.g., a time event. The MCF 625 is responsible for establishing data plane paths among CB instance (s) within the mission instance and between mission participants (e.g., UEs) and the CB instance (s) for the mission execution. When coordinating the mission execution, the MCF 625 triggers execution (s) of the CB (s) of the mission at right time and coordinates access of mission participants, e.g., devices, to the mission execution. The MCF 625 may control the mission execution with respect to relevant MM polices, which can be pre-configured at the MCF 625 or obtained by the MCF 625 from another control plane entity. Mission context related to the mission execution is maintained in the control plane and in the data plane before the mission execution is terminated. Without ambiguity, MCF and MCF network entity are used interchangeably for ease of presentation unless clarified.
[0169] MEF (Mission exposure function) 630. The MEF 630 exposes MM capabilities (services) to an AF and authenticates / authorizes requests from the AF for the MM capabilities. Via the MEF, an authorized AF can influence the system’s MM decisions. The MEF performs information mapping or resolution for information received from or transmitted to the AF. Possible information mapping includes mapping a mission external ID to a mission internal ID, a device external ID to a device internal ID, etc. Possible information resolution includes resolving a mission intent into a mission specification. Without ambiguity, MEF and MEF network entity are used interchangeably for ease of presentation unless clarified.
[0170] SCF (Service control function) 635. The SCF 635 assists the MEF 630 in resolving a mission intent into a mission specification. The SCF 635 is further responsible for preparing resources, e.g. control plane resources such as TCF (s) and data plane resources such as PSFs, within the corresponding service module. The prepared resources will be used to support an execution of a task of the mission within the service module, during the mission execution. Without ambiguity, SCF and SCF network entity are used interchangeably for ease of presentation unless clarified.
[0171] TCF (Task control function) 640. The TCF 640 controls and coordinates an execution of a task, including starting, stopping, terminating the task execution. The TCF 640 starts, stops or terminates the task execution, as part of a mission execution, according to a request from the MCF 625. The TCF 640 is informed by the MCF 625 that a network entity, e.g., a device, is accessing / participating the task execution. The TCF 640 can accordingly invite the network entity at right time, e.g., when task resources are ready, to access / participate the task execution, wherein the network entity may provide data to support the task execution or receives data related to the task execution. Task context related to the task execution is maintained in the control plane of the service module and in the data plane of the service module before the task execution is terminated. Without ambiguity, TCF and TCF network entity are used interchangeably for ease of presentation unless clarified.
[0172] PSF (Processing service function) 645. The PSF 645 receives and processes data plane traffic. The PSF 645 may generate data plane traffic. The PSF 645 may transmit its received data plane traffic (possibly after processing) or generated data plane traffic to other PSFs or the DN 660 or the UE 650 via one or multiple data plane gateways, a. k. a. data gateways (data GWs) 655, which are similar to UPFs (user plane functions) in the 5G system. Without ambiguity, PSF and PSF network entity are used interchangeably for ease of presentation unless clarified.
[0173] FIG. 7 shows a procedure of a NE accesses an application. As shown in the FIG. 7, the procedure 700 involves a mission (slice) , a mission (slice) instance, a mission session, an application and mission execution.
[0174] An application located in a DN can be a customer of a mission and provide an application service to its users by making use of an execution of the mission. The mission can support more than one application. A mission supports an application through a mission instance. A mission can act as an application and natively provides an application service to the application users; in this case, the application is considered located in the mission. An authorized NE uses a mission session to access the application, the mission session targeting a DN where the application is located and being supported by an instance of the mission. When the application is located in the mission, the DN is an abstract DN and corresponds to the mission. The mission instance can be used to support more than one application. Different applications may be supported by different instances of a mission.
[0175] In this example of FIG. 7, a mission (slice) 710 includes three types of CB, which are task CB (subnet) 711, sub-mission CB (subnet) 712 and external CB (subnet) 713. To support one or multiple applications, the mission (slice) 710 needs to be instantiated as one or more mission (slice) instance. In other words, instantiate the mission (slice) as one or multiple mission (slice) instance to support one or multiple applications. As we can see in the FIG. 7, the mission (slice) 710 is instantiated as a mission (slice) instance 720. The mission (slice) instances are used for the execution of the mission (slice) 710. Correspondingly, the mission (slice) instance 720 includes a task CB (subnet) instance 721 corresponding to the task CB (subnet) 711, a sub-mission CB (subnet) instance 722 corresponding to the sub-mission CB (subnet) 722 and an external CB (subnet) instance 723 corresponding to the external CB (subnet) 713. It is understandable that the mission (slice) 710 may also be instantiated as other mission (slice) instances. Further, a NE 730 access the application located in the DN 740 via the mission (slice) instance 720.
[0176] To support an application through a mission instance as described above, a mission session must be established over the mission instance. During the establishment of the mission session, both the data plane (e.g., data plane path (s) across CB instance (s) ) and the control plane (e.g., MCF (s) 625 and TCF (s) 640) are configured for the mission session. After the mission session establishment, data traffic related to the application can flow through the mission instance and be processed under the coordination of the MM framework, according to a networking logic (if any) associated to the mission. The process of coordinating the data flow and processing is referred to as mission execution.
[0177] The mission session is associated with one or multiple data sessions for the device. Each of the data session (s) corresponds to a CB instance in the mission instance, and the CB instance in turn corresponds to an access point of the mission. When accessing the application using the mission session, the device uses the data session (s) to interact with respective CB instance (s) . The interacting with the CB instance (s) involves data traffic and control signals and is part of the mission execution associated to the mission session.
[0178] In the example of FIG. 7, a mission session is established over the mission (slice) instance 720. Moreover, the mission session is associated with one or more data sessions. For example, in this example, the mission session is associated with a data session between the NE 730 and the task CB (subnet) instance 721, and another data session between the NE 730 and the sub-mission CB (subnet) instance 722, as shown by a solid line with a double-headed arrow in the FIG. 7. It is understandable that there may exist a data session between the NE 730 and the external CB (subnet) instance, although it is not shown in the FIG. 7. Besides, the application located in the DN 740 may get support from the mission (slice) instance, for example, there existed a session between the sub-mission CB instance 722 and the DN 740, and another session between the external CB instance 723 and the DN 740, as shown by a dashed line with a double-headed arrow in the FIG. 7.
[0179] A mission is identified by a mission ID (MID) . The MID may be in the form of a network slice ID. The MID may be associated with one or multiple CB IDs (CBIDs) , each identifying a CB of the mission. When a CB is an external CB, the CBID identifying the CB may be in the form of DNN. When a CB is a sub-mission CB, the CBID identifying the CB may be in the form of MID. It is possible that the MID is not associated with any CBID, for example, when the mission includes no CBs.
[0180] An instance of the mission is identified by a mission instance ID (MIID) . The MIID may be in the form of a network slice instance ID.The MIID may be associated with one or multiple CB instance IDs (CBIIDs) . Each of the one or multiple CBIIDs identifies a CB instance in the mission instance. The CB instance is an instance of a CB of the mission. When the CB is a sub-mission CB, the CBIID may be in the form of an MIID. It is possible that the MIID is not associated with any CBIID, for example, when the mission includes no CBs.
[0181] An application is identified by an application service ID (ASID) . The ASID may be in the form of a DNN. An MIID may be corresponded to one or multiple ASIDs, indicating that the mission instance identified by the MIID is being associated to (i.e., used to support) the application (s) identified by the one or multiple ASIDs. In some embodiments, an application is identified by an application ID (AID) .
[0182] During establishment of a mission session for an application, a mission instance associated to the application is selected. The selection of mission instance may be pre-configured, or dynamically determined in the MM framework. In the former case, the MM frame can identify the mission instance based on an ASID of the application. For example, there is a pre-configured correspondence relation between the mission instance and the ASID of the application and the MM frame can identify the mission instance according to the pre-configured correspondence relation. In the latter case, the MM framework additionally uses mission selection assistance information (MSAI) to identify and select the mission instance. The MSAI may include a list of MID (s) or a list of MIID (s) . When a list of MID (s) is (are) included in the MSAI, the MM framework selects an instance of a mission identified in the list. For example, any mission instance of any mission identified in the list can be selected by the MM framework. When a list of MIID (s) is (are) included in the MSAI, the MM framework selects a mission instance identified in the list. The mission session can then be identified globally by a combination of the ASID of the application and the MIID of the mission instance.
[0183] The mission session is established upon request from an authorized device or AF. When requesting to establish the mission session, the device or AF provides the ASID and the MSAI. At a device, the mission session is identified locally using a mission session ID (MSID) and associated with a mission session context. The mission session context may include one or multiple data session IDs (DSIDs) , each identifying a data session related to a task CB instance or a DN CB instance in the mission instance. The mission session context may also include one or multiple MSIDs, each of which identifies a mission session corresponding to a sub-mission CB instance in the mission instance.
[0184] Among the identifiers described above, MSID, DSID, and ASID are understandable by the device; MID and CBID can be embedded in or mapped to other information such as MSAI, and are not be directly understandable by the device. MIID and CBIID are network-side concepts, not visible to the device.
[0185] As described above, a mission is associated with a mission template, which describes the mission. For example, the mission template includes one or multiple information elements as illustrated in the Table 1.
[0186] Table 1 Mission template

[0198] The mission specification includes composition information, workflow information and access point information as further described below, any of which is optional.
[0199] The composition information identifies CB (s) of the mission and, if the mission include multiple CBs, specifies interconnection (s) between the multiple CBs. For each CB, the composition information may further indicate one or multiple associated mission parameters. For a task CB, the composition information indicates the respective supporting service module (e.g., using a module ID) . For an external CB, the composition information indicates the respective supporting DN (e.g., using a DNN) . For a sub-mission CB, the composition information indicates the respective mission (e.g., using an MID) . When specifying an interconnection between two CBs, this information may describe interfaces between the two CBs. For a CB, the composition information may indicate whether the CB is a stateless CB or not.
[0200] The workflow information specifies a networking logic among the CBs identified in the composition information, e.g. ordering or timing between the CBs. This information may indicate which CB (s) follow (s) or proceed (s) which other CB (s) .
[0201] The access point information specifies access point (s) of the mission, each of which is a CB of the mission and identified by a CBID. When specifying an access point, this information may indicate interface (s) associated to the access point as described in the Interface information, for example, by including one or multiple IDs or names that identify the interface (s) .
[0202] An instance of a mission (i.e. a mission instance) is described using a mission instance information. The mission i.e., a mission instance includes one or multiple information elements as illustrated in the Table 2.

For a CB instance, this information includes a list of CBIAI (s) , each identifying an access point to the CB instance. If two CB instances should be interconnected (e.g., as described in the mission information associated to the mission) , this information may further indicate how the two CB instances are interconnected, for example, by including a list of tunnel information (s) each corresponding to a tunnel between an access point of one of the CB instances and an access point of the other CB instance. A tunnel information may include, e.g., a tunnel ID, a tunnel end point ID, and a tunnel protocol ID.
[0209] Execution pattern information, which describes a pattern of executing the mission on the mission instance.
[0210] This information describes when (for example, in the forms of time of the day, time of the week, time of the month, time of the year) or under what condition (s) (for example, in the forms of event IDs) an execution of the mission on the mission instance should be started, paused, resumed, stopped, or terminated.
[0211] Authorization information, which indicates device (s) that are allowed to access the mission instance.
[0212] This information may include a of list of ID (s) or network address (es) , each identifying a device or a device group. This information may include one or multiple wildcards. A device identified in, or belonging to a device group identified in this information is considered allowed to access the mission instance.
[0213] Temporal validity condition. This information indicates when (e.g. in terms of time) the mission instance is valid or available. The temporal validity condition can be expressed by one or multiple time-intervals or durations, each being associated with a start time and possibly an end time too.
[0214] Spatial validity condition. This information indicates where the mission instance is valid or available. The spatial validity condition can be expressed by a list of zone ID (s) , each identifying a geographic area, a list of PLMN ID (s) , or a list of cell ID (s) or a combination thereof.
[0215] Application information, which indicates a list of application (s) that the mission instance is associated to. This information may include a list of ASID (s) , each identifying an application. For each application, this information further specifies value (s) for mission parameter (s) of the mission. The mission parameter (s) is (are) specified in the mission template associated to the mission as described in the Table 1. The mission parameter (s) is (are) parameter (s) associated to the mission and related to, functionalities / behaviors of one or multiple CBs in the mission.
[0216] The structure for mission management and some concepts relating to a mission are described above referring to FIG. 6 and FIG. 7. In the following, a procedure for subscribing information related to a mission or a mission instance will be described.
[0217] In some embodiments, description information related to a mission is stored in a first storage function. And description information related to a mission instance is stored in a second storage function. The first storage function and the second storage function can be the same storage function or different storage functions. For example, mission template, which is the description information related to a mission, is stored in the MDR 615. Mission instance information, which is the description information related to a mission instance, is stored in the MIR 620. It can be seen that in this example, the mission template and the mission instance information are stored in different storage functions. In some cases, an information change may happen. The information change refers to a change happened to information, which is either description information related to a mission (for example, a mission template) or description information related to a mission instance (for example, mission instance information) . The information change corresponds to an addition, a modification or a deletion of the information. Further, the addition refers to adding new information element (s) to a mission template related to a mission or adding new information element (s) into mission instance information related to a mission instance. For example, an original mission template includes no temporal validity condition, and the temporal validity condition is added to the original mission template. For another example, original mission instance information incudes no instantiation information, and the instantiation information is generated and added to the mission instance information later. In the above two examples, the information change corresponds to an addition. In some cases, “addition” is not only for adding new information elements into an existing mission template or mission instance information, the “addition” also corresponds to creating a mission template or mission instance information in the storage function. The modification refers to change (s) related to existed information element (s) in a mission template or mission instance information. For example, a mission template related to a mission includes a reusability indication. The reusability indication may be modified from indicating the mission can be used as an CB in another mission to indicating the mission can not be used as an CB in another mission. For another example, mission instance information related to a mission instance incudes execution pattern information, and the execution information may be modified from one pattern of executing a mission on the mission instance to another pattern of executing the mission on the mission instance. In the above two examples, the information change corresponds to a modification of the mission and the mission template, respectively. The deletion refers to removing at least part of a mission template or mission instance information. For example, a deletion operation related to a mission may include removing one or more information elements of a mission template, even removing the entire mission template of the mission. For another example, a deletion operation related to a mission instance may include removing one or more information elements of mission instance information, even removing the entire mission instance information, of the mission instance. In some embodiments, if the information change happens to a mission, the deletion includes a physical deletion or a logical deletion. The physical deletion indicates that the description information related to the mission (for example, a mission template related to the mission) is removed from a storage. In other words, after the physical deletion, the mission is no longer useable. That is, the state of the mission corresponding to the physical deletion is that the mission is unusable. The logical deletion indicates that the description information related to the mission (that is, the mission template related to the mission) is stored in a storage and has been processed. In this case, the state of the mission corresponding to the logical deletion is that the mission is deprecated. In other words, after the logical deletion (also referred to as logical delete) , the mission template is still in storage, but the mission is considered depreciated or deprecated, and no new mission instances should be created for the mission. Similarly, if the information change happens to a mission instance, the deletion also includes a physical deletion or a logical deletion. The physical deletion indicates that the description information related to the mission instance (for example, mission instance information) is removed from a storage. In other words, after the physical deletion, the mission instance is no longer useable. That is, the state of the mission instance corresponding to the physical deletion is that the mission instance is unusable. The logical deletion indicates that the description information related to the mission instance (that is, the mission instance information) is stored in a storage and has been processed. In this case, the state of the mission instance corresponding to the logical deletion is that the mission instance is deprecated. In other words, after the logical deletion (also referred to as logical delete) , the mission instance information is still in storage, but the mission instance is considered depreciated or deprecated, and no new CB instances should be created for the mission instance.
[0218] In some embodiments, an authorized NF can subscribe to receive notifications about information change (s) associated to information of interest. Nature of the NF is not limited. The NF can be a control plane function, e.g., MDR 615, MIR 620, MCF 625, AF 610, or any other network entity. Depending on whether the information of interest is mission template or mission instance information, the notifications are sent from the corresponding storage function, i.e., the MDR 615 or the MIR 620, as shown by the FIG. 6.
[0219] In some embodiments, the subscription indicates the information of interest. When the information of interest is mission template, the information of interest is indicated by a mission filter. That is, the mission filter identifies mission (s) of interest. The information of interest includes mission template (s) of the mission (s) of interest identified by the mission filter.
[0220] In some implementations, the mission filter includes one or more mission IDs, each identifying each identifying one mission of the at least one mission respectively (that is, each identifying a mission of interest) . In other words, the mission filter may be described using a list of MID (s) , each identifying a mission as a mission of interest. In some implementations, the mission filter includes one or more service IDs, each identifying a service corresponding to one mission of the at least one mission respectively (that is, each identifying a service corresponding to a mission of interest) . For example, a service identified by a service ID of the one or more service IDs is related to a mission of interest, for example, there is a corresponding relation between the service and the mission so that the mission can be determined based on the service ID and the corresponding relation. In other words, a mission whose mission intent matches the service problem ID (s) may be a mission of interest. In some implementations, the mission filter includes one or more service problem IDs, each identifying a service problem corresponding to a mission of the at least one mission respectively. (that is, each identifying a service problem corresponding to a mission of interest) . In this case, a mission whose mission intent matches the service problem ID (s) may be a mission of interest. In some implementations, the mission filter includes one or more application IDs, each identifying an application corresponding to one mission of the at least one mission respectively (that is, each identifying an application corresponding to a mission of interest) . As described above, a mission of interest may provide service to an application so that there is a correspondence relation between the mission and the application. Consequently, the mission of interest can be determined based on the application ID. In other words, the mission filter may be described using a list of ASID (s) or a list of AID (s) , and a mission that is associated to an application identified by an ASID or an AID in the list is a mission of interest. In some implementations, the mission filter includes one or more application category IDs, each identifying an application category corresponding to a mission of interest. In other words, the mission filter may be described using application category ID (s) / and / or application ID and / or service problem ID (s) / and / or service ID (s) . In this case, a mission whose mission intent matches the application category ID (s) and / or service problem ID (s) may be a mission of interest. The mission’s mission intent is described using a list of application category ID (s) and / or a list of service problem ID (s) (simply put, problem ID (s) ) , as described in embodiments associated to the Table 1. The mission intent matches the application category ID(s) and / or service problem ID (s) if the list of application category ID (s) includes one of the application category ID (s) and / or if the list of service problem ID (s) includes one of the service problem ID (s) . In some implementations, the mission filter may include one or more zone IDs, each identifying an area where the at least one mission is valid. That is, the mission filter may further be described using area (s) of interest, each being identified by a zone ID. In this case, a mission that is valid in the area (s) of interest may be a mission of interest.
[0221] In some embodiments, any mission is a mission of interest. For example, the at least one mission (of interest) may be indicated by a first indication indicating any mission. The first indication may be in the form of one of a special mission ID, a special service ID, a special application ID, or a special service problem ID. In some examples, the special mission may be a virtual mission rather a certain actual mission and the virtual mission ID indicates any mission. Similarly, the special service may be a virtual service rather a certain actual service and the virtual service ID indicates any service corresponding to any mission. The special application may be a virtual application rather a certain actual application and ID of the virtual application indicates any application corresponding to any mission. The special service problem may be a virtual service problem rather a certain service problem and ID of the virtual service problem indicates any service problem corresponding to any mission.
[0222] In some embodiments, when the information of interest is mission instance information, the information of interest is indicated by a mission instance filter. The mission instance filter identifies mission instance (s) of interest. The information of interest includes mission instance information of the mission instance (s) of interest identified by the mission instance filter.
[0223] In some implementations, the mission instance filter includes one or more mission instance IDs, each identifying one mission instance of the at least one mission instances respectively (that is, each identifying a mission instance of interest) . In other words, the mission instance filter may be described using a list of MIID (s) , each identifying a mission instance as a mission instance of interest. In some implementations, the mission instance filter includes one or more mission IDs, each identifying one mission of the at least one mission respectively, and for each mission of the one or more missions identified by the one or more mission IDs, the one or more mission instances of the said mission belong to the at least one mission instance. In other words, a mission instance of at least one mission identified by the one or more mission IDs is a mission of interest. That is, the mission instance filter may be described using a list of MID(s) , each identifying a mission, and an instance of a mission identified by an MID in the list is a mission instance of interest. For example, the mission instance filter includes MID 1. Then any instance of the mission identified by the MID 1 is a mission instance of interest. In some implementations, the mission instance filter includes MSAI, wherein the mission instance of interest is determined according to the MSAI as described above. In other words, the mission instance filter may be described using a list of MSAI (s) , and a mission instance that can be selected according to an MSAI in the list is a mission instance of interest. In some implementations, the mission instance filter includes one or more application service IDs or one or more application IDs, identifying one or more applications respectively, wherein a mission instance that is associated to the one or more applications identified by the one or more application service IDs or the one or more application IDs belongs to the at least one mission instance. In other words, a mission instance that is associated to one or more applications identified by the one or more application service IDs or the one or more application IDs is a mission instance of interest. In other words, the mission instance filter may be described using a list of ASID (s) or a list of AID (s) , and a mission instance that is associated to an application identified by an ASID or an AID in the list is a mission instance of interest. In some implementations, the mission instance filter includes one or more zone IDs, each identifying an area where the at least one mission instance is valid. In other words, the mission instance filter may further be described using area (s) of interest, each of which can be identified by a zone ID. A mission instance that is valid in the area (s) of interest may be a mission instance of interest.
[0224] In some embodiments, any mission instance is a mission instance of interest. For example, the at least one mission instance (of interest) may be indicated by a second indication indicating any mission instance. The second indication may be in the form of one of a special mission instance ID, a special service ID, a special application ID, or a special service problem ID.
[0225] In some embodiments, according to the subscription, the storage function notifies the NF about the information change (s) . For an information change, the notification indicates type of change, e.g., addition, modification or deletion. When the information of interest is mission template, the notification includes all or some of the content of mission template that the information change is related to, e.g., the spatial validity condition, the temporal validity condition, the reusability indication, the interface information, the mission intent, the application indication, etc., as described in the Table 1. When the information of interest is mission instance information, the notification includes all or some of the content of mission instance information the information change is related to, as described in the Table 2.
[0226] As shown in FIG. 8, the subscription-notification (notification-subscription) procedure includes part or all the following steps.
[0227] In step 810, the NF 710 subscribes to receive notifications about information change associated to mission (s) of interest, by sending a subscription request.
[0228] In some embodiments, as described above, the NF 710 sends a request to a storage function 720, for example, the MDR 615 or the MIR 620. The subscription request (in the steps 810a, 810b and 810c) indicates information of interest, and the information of interest includes information related to a mission or a mission instance. That is, the NF 710 sends a request for at least one mission and / or at least one mission instance. As mentioned above, when the information of interest is related to a mission, the mission is indicated by a mission filter, which includes one of: one or more mission IDs, each identifying a mission of the at least one mission; one or more service IDs, each identifying a service corresponding to the at least one mission; one or more service problem IDs, each identifying a service problem corresponding to the at least one mission; one or more application IDs, each identifying an application corresponding to the at least one mission; one or more application category IDs, each identifying an application category corresponding to the at least one mission; or one or more zone IDs, each identifying an area where the at least one mission is valid. The details related to the mission filter has been described, here we do not go into details.
[0229] In some embodiments, as mentioned above, when the information of interest is related to a mission instance, the mission instance is indicated by a mission instance filter, which includes one of: one or more mission instance IDs, each identifying a mission instance of the at least one mission instances; one or more mission IDs, wherein a mission instance of at least one mission identified by the one or more mission IDs belongs to the at least one mission instance; mission selection assistance information, wherein the at least one mission instance is determined according to the mission selection assistance information; one or more application service IDs or one or more application IDs, wherein a mission instance that is associated to one or more applications identified by the one or more application service IDs or the one or more application IDs belongs to the at least one mission instance; or one or more zone IDs, each identifying an area where the at least one mission instance is valid.
[0230] In some embodiments, there are two possible implementations for the NF 710 to send the subscription request. The embodiments of the present disclosure are not limited to the two implementations.
[0231] In one implementation, as shown in steps 810a and 810b, the NF710 subscribes to the notifications via another network entity, for example, the MEF 630, e.g., when the NF 710 is an AF 610. In this case, the NF 710 sends the subscription request to the MEF 630 (as shown in step 810a) . According to the subscription request, the MEF 630 may subscribe to receive the notifications from the storage function 720. To do so, the MEF 630 sends a subscription request to the storage function 720 (as shown in step 810b) . The subscription request sent from the MEF 630 to the storage function 720 (for example, the MDR615) indicates a subscription of the MEF 630 for the notifications. The subscription request in the step 810b includes information in the subscription request in the step 810a.
[0232] In some embodiments of the present disclosure, the NF 710 is referred to as a first network function and the ‘another network entity’ as described above is referred to as a second network function. Besides, the second network function is not limited to the MEF 630 in the present disclosure.
[0233] In another implementation, as shown in step 810c, the NF 710 subscribes to the notifications without involving the MEF630, e.g., when the NF 710 is a policy control function (PCF) . In this case, the NF 710 sends a subscription request to the storage function 720 (step 810c) .
[0234] In the embodiments of the present disclosure, the steps 810a, 810b and 810c are generically referred to as step 810.
[0235] In some embodiments, the request includes time information for indicating when to send the specified information. For example, the time information includes one or more time intervals, and each time interval is associated with a start time and / or an end time. That is, the subscription request (in the steps 810a, 810b and 810c) may include a temporal validity condition, which indicates when (e.g., in terms of time) the subscription is valid. For example, the temporal validity condition is expressed by one or multiple time-intervals or durations, each being associated with a start time and / or an end time too. For another example, the temporal validity condition may indicate that the subscription is valid anytime. The notifications should be generated or sent to the NF 710 only when the subscription is valid as indicated by the temporal validity condition. For example, the temporal validity condition is expressed by a time-interval, such as “15: 00-18: 00” which includes both a start time and an end time and indicates that the subscription is only valid in the time-interval.
[0236] In some embodiments, the NF 710 further sends an indication to the storage function 720, wherein the indication indicates whether the request corresponds to a one-time response or continuous responses. The indication may be included in the subscription request. In other words, the subscription request (in the steps 810a, 810b and 810c) may further indicate whether the subscription is to a one-time notification or to continuous notifications. If the subscription is to a one-time notification, the NF 710 will receive the notification when the storage function 720 responds to the request, as further described in the step 820. If the subscription is to continuous notifications, the NF 710 will continue to receive such notifications whenever change happens to the information of interest during the time that the subscription is valid. Please be noted that the temporal validity condition is optional when the subscription is to a one-time notification.
[0237] In step 820, the storage function 720 responds to the subscription request received in the step 810 by using a subscription response. The subscription response acknowledges the recipient of the subscription request. The subscription response may include the subscribed notification.
[0238] In some embodiments, if the subscription request is received from the MEF 630 as indicated by the step 810b, the storage function 720 sends the subscription response to the MEF 630 as indicated by the step 820a. In this case, as indicated by the step 820b, the MEF 630 accordingly responds to the NF 710 for the subscription request in the step 810a. The response sent from the MEF 630 to the NF 710 includes information in the subscription response. If the subscription request is received from the NF 710 (as shown in the step 810c) , the subscription response is sent to the NF 710 as indicated by the step 820c.
[0239] In step 830, the storage function 720 updates (e.g., adds, modifies or deletes) information in storage, causing change (s) related to the information of interest as identified in the subscription (i.e., the request in the step 810) .
[0240] Updating information in storage includes addition, modification, deletion of the information as described above, here do not go into details. Besides, updating the information in storage may happen according to practice needs. For example, the information changes may happen according to a request from a network entity. The order of steps 810, 820 and 830 is not limited to this in the FIG. 8 in the embodiments of the present disclosure.
[0241] In step 840, the storage function 720 sends a notification to the NF 710. Accordingly, the NF 710 receives the notification.
[0242] In some embodiments, according to the subscription indicated in the subscription request (e.g., step 810b or 810c) , the storage function 720 sends a notification about the information change.
[0243] In some embodiments, if the subscription request is received from the MEF 630 as indicated by the step 810b, the storage function 720 sends the notification to the MEF 630. In this case, the MEF 630 accordingly sends a notification to the NF 710. The notification sent from the MEF 630 to the NF 710 includes information in the notification that the MEF 630 received from the storage function 720. If the subscription request is received from the NF 710 (the step 810c) , the notification is sent to the NF 710.
[0244] In some embodiments, the NF 710 receives specified information from the storage function 720, wherein the specified information is related to the at least one mission indicated by the mission filter and / or the at least one mission instance indicated by the mission instance filter in the subscription request as described above. For example, the NF 710 receives the specified information which is included in the notification.
[0245] In some embodiments, if the at least one mission indicated by the mission filter in the subscription request includes at least one first mission, wherein first description information (for example, the mission template as described in table 1) related to the at least one first mission has been modified, and the specified information related to the at least one first mission includes at least part of the first description information related to the at least one first mission and the at least part of the first description information includes the modified first description information. For example, the reusability indication related to mission A has been modified, the specified information related to the mission A includes the modified reusability indication.
[0246] Similarly, in some embodiments, if the at least one mission instance indicated by the mission instance filter in the subscription request includes at least one first mission instance, wherein second description information (for example, the mission instance information as described in table 2) related to the at least one first mission instance has been modified, and the specified information related to the at least one first mission instance includes at least part of the second description information, and the at least part of the second description information includes the modified second description information. For example, the execution pattern information related to mission instance B has been modified, the specified information related to the mission instance B includes the modified execution pattern information.
[0247] In some embodiments, if the at least one mission includes at least one second mission that has been created, and the specified information related to the at least one second mission includes third description information (for example, the mission template as described in table 1) related to the at least one second mission. For example, a mission C is newly created, an information change related to the mission C includes the mission template related to the mission C.
[0248] Similarly, in some embodiments, if the at least one mission instance includes at least one second mission instance that has been created, and the specified information related to the at least one second mission instance includes fourth description information (for example, mission instance information) related to the at least one second mission instance. For example, a mission instance D has been newly created, an information change related to the mission instance D includes mission instance information related to the mission instance D.
[0249] In some embodiments, if the at least one mission includes at least one third mission that has been deleted, the specified information related to the at least one third mission includes fifth description information (for example, mission template) related to the at least one third mission. For example, if a mission E has been deleted, an information change related to the mission E happens. In this example, the specified information related to the mission E includes the mission template related to the mission E.
[0250] Similarly, in some embodiments, if the at least one mission instance includes at least one third mission instance that has been deleted and the specified information related to the at least one third mission instance includes sixth description information (for example, mission instance information) related to the at least one third mission instance. For example, if a mission instance F has been deleted, the specified information related to the mission instance F includes the mission template related to the mission instance F as described in table 1,
[0251] In some embodiments, any of the second description information related to the at least one first mission instance, the fourth description information related to the at least one second mission instance, and the sixth description information (for example, mission instance information) related to the at least one third mission instance includes at least one of: a mission instance ID of a corresponding mission instance; a mission ID of a mission related to the corresponding mission instance; instantiation information, wherein the instantiation information describes computing block (CB) instances in the corresponding mission instance; execution pattern information, wherein the execution pattern information describes a pattern of executing the mission on the corresponding mission instance; authorization information, wherein the authorization information indicates at least one device allowed to access the corresponding mission instance; a temporal validity condition, wherein the temporal validity condition indicates when the corresponding mission instance is valid; a spatial validity condition, wherein the spatial validity condition indicates where the corresponding mission instance is valid; application information, wherein the application information indicates at least one application that the corresponding mission instance is associated to, and for each application, the application information specifies at least one mission parameter value.
[0252] In some embodiments, the NF 710 further obtains a type of change corresponding to the specified information. The type of change may be included in the notification. For example, the type of change includes any one of the following: a modification type indicating that the first description information of the at least one first mission and / or the second description information of the at least one first mission instance has been modified; an addition type indicating that the third description information of the at least one second mission and / or the fourth description information of the at least one second mission instance has been created; or a deletion type indicating that the fifth description information (for example, mission template) of the at least one third mission and / or the sixth description information (for example, mission instance information) of the at least one third mission instance has been deleted.
[0253] In some embodiments, the deletion type includes a physical deletion type or a logical deletion type, wherein the physical deletion type indicates that the fifth description information (for example, mission template) is removed from a storage and the third mission is unusable or the sixth description information (for example, mission instance information) is removed from a storage and the third mission instance is unusable; the logical deletion indicates that the fifth description information (for example, mission template) is stored in a storage and has been processed and the third mission is deprecated or the sixth description information (for example, mission instance information) is stored in a storage and has been processed and the third mission instance is deprecated. In other words, in both cases of the information change being related to a mission or a mission instance, the deletion type includes a physical deletion type or a logical deletion which has been described above.
[0254] In some embodiments, if the subscription request includes a temporal validity condition, the storage function 720 performs this step 840 only when the subscription is valid as indicated by the temporal validity condition. This step is optional when the subscription is to a one-time notification.
[0255] The embodiments described in accordance with the FIG. 8 allows the NF to dynamically subscribe to receive information about missions or mission instances of interest. According to the received information, the NF can determine whether and how to use a mission or mission instance (e.g. whether the mission can solve certain problems, whether to use the mission as a sub-mission to create a new mission, avoid using a depreciated mission, use the mission instance at right time and right location, etc. ) .
[0256] FIG. 9 shows a flow chart illustrating a method by a network function in accordance with some embodiments of the present disclosure. In step 910, the NF sends a request for at least one mission and / or at least one mission instance to a storage function network entity; and in step 920, the NF receives specified information from the storage function network entity in the case where information related to the at least one mission and / or the at least one mission instance changes, wherein the specified information is related to the at least one mission and / or the at least one mission instance, each mission of the at least one mission comprises one or more mission instances.
[0257] FIG. 10 shows a flow chart illustrating a method by a storage function in accordance with some embodiments of the present disclosure. In step 1010, the SF receives a request from a first network function, wherein the request is for at least one mission and / or at least one mission instance; and in step 1020, the SF sends specified information related to the at least one mission and / or the at least one mission instance to the first network function in the case where information related to the at least one mission and / or the at least one mission instance changes.
[0258] Some embodiments of the present disclosure provide a network device. The network device is used for performing some steps of the method for information processing as described in the above embodiments / implementations. As shown in FIG. 11, the network device 1100 includes a processing module 1101 and a communication module 1102. The processing module 1101 is used for processing data units / signals. The communication module 1102 is used for transmitting (sending) and / or receiving data units / signals.
[0259] For example, the communication module 1102 may include communication interface (s) .
