Description

Apparatus, method, device and readable storage medium for controlling function relocation Cross Reference to Related Applications The present application relates to and claims priority to U.S. provisional patent application No. 63/594,060 entitled "Method, apparatus, and system control function relocation" filed 10/30/2023, the entire contents of which are incorporated herein by reference. Technical Field The present invention relates to the field of communications technologies, and in particular, to an apparatus, a method, a device, and a readable storage medium for controlling function relocation. Background As wireless networks evolve and evolve, communication networks tend to have a completely new architecture. For example, a 6G network will provide new network infrastructure, such as widely deployed cloud infrastructure, as well as new processing technologies, such as artificial intelligence large scale models, data privacy protection, blockchains, etc. The proposed 6G network may perform a mission to provide a service to a user, for example, perform a mission requested from a certain application to provide a service to a user of the application. Each mission may be divided into at least one task, and during mission execution (mission execution, ME), a task control function (task control function, TCF) may control and coordinate Task Execution (TE). But TCF may require relocation. For example, as mission content increases, computing/communication resources on network entities embedded in the TCF may no longer be sufficient to support TE management, and thus the TCF may need to be replaced by a new TCF. Disclosure of Invention In view of the above, an apparatus, method, device and readable storage medium for controlling function relocation are described in which relocation from o-TCF to n-TCF is effected. According to a first aspect, a first device is described comprising at least one processor coupled with at least one memory storing computer program code, wherein the computer program code, when executed by the at least one processor, causes the first device to determine that a first task performed by a first task control function (task control function, TCF) is to be replaced by a second TCF, wherein the first TCF and the second TCF are managed by a mission management (mission management, MM), send a first synchronization request to the first TCF that includes information of the second TCF to request the first TCF to send Task Execution (TE) information to the second TCF, wherein the TE information includes execution information of the first task performed by the first TCF. According to some embodiments, the first task may include one or more tasks performed by the first TCF. In the case where the TCF needs to be relocated, upon switching from the first TCF to the second TCF, the MM may trigger synchronization of the first TCF and the second TCF to transfer the first task to the second TCF. Thus, the second TCF may manage execution of the first task to achieve successful relocation from the first TCF to the second TCF. In a possible implementation manner of the first aspect, the computer program code, when executed by the at least one processor, further causes the first device to send a first update request including the information of the second TCF to the first TCF to request that a TCF managing a processing service function (processing service function, PSF) be updated from the first TCF to the second TCF. In a possible implementation manner of the first aspect, the information of the second TCF includes at least one of an Identifier (ID), a name, a location, and a validity time. In a possible implementation manner of the first aspect, the computer program code, when executed by the at least one processor, further causes the first device to send a configuration request to the second TCF, the configuration request including information of the first TCF and a first synchronization rule. In a possible implementation manner of the first aspect, the information of the first TCF includes at least one of an ID, a name and a location of the first TCF. In a possible implementation manner of the first aspect, the first synchronization rule includes a first interface, and first setup information for synchronizing the second TCF. In a possible implementation manner of the first aspect, the first synchronization request is further configured to request the first TCF to send a suspension request to a PSF managed by the first TCF, where the suspension request indicates the PSF to suspend a process of the first task. In one possible implementation of the first aspect, the computer program code, when executed by the at least one processor, further causes the first device to receive a relocation complete notification from the second TCF. In one possible implementation of the first aspect, the computer program code, when executed by the at least one processor, further causes the first device to send a release request
