The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed is a method of creating or updating an application context in a Multi-access Edge Computing, MEC, system, comprising the steps of: a) a device application posting a request to the MEC system to create or update the application context and to specify desired application location constraints; b) the MEC system authorising the request and creating or updating the application context in the MEC system and informing the device application accordingly; and c) the MEC system detecting a change in application location availability. ## Claims ### Claim 1 A method for a multi-access edge computing (MEC) service by a device application included in a user equipment (UE) in an MEC system, the method comprising: transmitting, to a user application lifecycle management proxy (UALCMP) within the MEC system, a first POST request to obtain a list of locations available for instantiation of a specific user application; receiving, from the UALCMP, a first response message including a list of available constrained locations for the specific user application; transmitting, to the UALCMP, a second POST request for an application context to be created; and receiving, from the UALCMP, a second response message including a created application context, wherein the second POST request includes an indication that instantiation of the requested application is desired in case that the constrained locations become available that wasn't at a time of the request. ### Claim 2 (depends on 1) The method of claim 1, wherein the second POST request is generated based on the list included in the first response message. ### Claim 3 (depends on 1) The method of claim 1, wherein the first POST request includes a callback reference address of the device application and a data structure pertinent to the specific user application, and wherein the second POST request includes an application context information. ### Claim 4 (depends on 1) The method of claim 1, further comprising: receiving, from the UALCMP, a first message including updated application context based on an application context information and the indication; and transmitting, to the UALCMP, a response to the first message. ### Claim 5 (depends on 1) The method of claim 1, further comprising: transmitting, to the UALCMP, a first message including application location constraints and a flag requesting to subscribe to a notification of change of application location constraint; and receiving, from the UALCMP, a response to the first message. ### Claim 6 (depends on 5) The method of claim 5, further comprising: receiving, from the UALCMP, a first message including updated application context based on a subscription; and transmitting, to the UALCMP, a response to the first message. ### Claim 7 (depends on 1) The method of claim 1, wherein a callback reference address includes a notification endpoint. ### Claim 8 A method for providing a multi-access edge computing (MEC) service to a device application by a user application lifecycle management proxy (UALCMP) in a MEC system, the method comprising: receiving, from the device application included in a user equipment (UE), a first POST request to obtain a list of locations available for a specific user application, the first POST request including a data structure pertinent to the specific user application; authorizing the first POST request received from the device application; evaluating the list of locations for user application instantiation available requested from the device application through the MEC system; transmitting, to the device application, a first response message including a list of available constrained locations for the specific user application based on the evaluation result; receiving, from the device application, a second POST request for an application context to be created; authorizing the second POST request received from the device application; forwarding, to the MEC system, the second POST request; and transmitting, to the device application, a second response message including a created application context, wherein the second POST request includes an indication that instantiation of the requested application is desired in case that the constrained locations become available that wasn't at a time of the request. ### Claim 9 (depends on 8) The method of claim 8, wherein the second POST request includes an application context information. ### Claim 10 (depends on 8) The method of claim 8, further comprising: transmitting, to the device application, a first message including updated application context based on an application context information and the indication; and receiving, from the device application, a response to the first message. ### Claim 11 (depends on 8) The method of claim 8, further comprising: receiving, from the device application, a first message including application location constraints and a flag requesting to subscribe to a notification of change of application location constraint; and transmitting, to the device application, a response to the first message. ### Claim 12 (depends on 11) The method of claim 11, further comprising: transmitting, to the device application, a first message including updated application context based on a subscription; and receiving, from the device application, a response to the first message. ### Claim 13 A user equipment (UE) for receiving a multi-access edge computing (MEC) service, the UE comprising: a transceiver for communicating with an MEC system; a memory; and at least one processor configured to run a device application for receiving a service from the MEC system, wherein the device application configured to control to: transmit, to a user application lifecycle management proxy (UALCMP) within the MEC system, a first POST request to obtain a list of locations available for instantiation of a specific user application, and receive, from the UALCMP, a first response message including a list of available constrained locations for the specific user application, transmit, to the UALCMP, a second POST request for an application context to be created; and receive, from the UALCMP, a second response message including a created application context, wherein the second POST request includes an indication that instantiation of the requested application is desired in case that the constrained locations become available that wasn't at a time of the request. ### Claim 14 (depends on 13) The UE of claim 13, wherein the second POST request is generated based on the list included in the first response message. ### Claim 15 (depends on 13) The UE of claim 13, wherein the second POST request includes an application context information. ### Claim 16 (depends on 15) The UE of claim 15, wherein the device application further configured to control to: receive, from the UALCMP, a first message including updated application context based on the application context information and the indication; and transmit, to the UALCMP, a response to the first message. ### Claim 17 (depends on 13) The UE of claim 13, wherein the device application further configured to control to: transmit, to the UALCMP, a first message including application location constraints and a flag requesting to subscribe to a notification of change of application location constraint; and receive, from the UALCMP, a response to the first message. ### Claim 18 (depends on 17) The UE of claim 17, wherein the device application further configured to control to: receive, from the UALCMP, a first message including updated application context based on a subscription; and transmit, to the UALCMP, a response to the first message.
