The disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate after a 4G communication system such as LTE. A method according to an embodiment of the disclosure is a control method in an edge enabler server (EES) of a mobile edge computing system, and may include subscribing to a user plane path change event at an edge application server (EAS); determining an application context relocation (ACR) based on receiving a user plane path management event notification from the mobile communication network in case of subscribing to the user plane path change event for the EAS; transmitting an ACR request message to the EAS; receiving an EAS response message from the EAS; and transmitting an application function (AF) acknowledgment message to a first node of the mobile communication network in response to receiving the EAS response message from the EAS.

A method performed by a child Integrated Access Backhaul (IAB) node that comprises a IAB-Mobile Termination, IAB-MT includes transmitting, to a network node operating as a parent node with respect to the child IAB node, a Radio Resource Control (RRC) setup request message comprising an IAB indication that indicates that the transmission to the network node is by the child IAB node comprising the IAB-MT.

There is provided mechanisms for enabling discovery of a service-providing NF in a 3GPP communication network. A method is performed by a Network Repository Function. The method comprises registering locality information of service-providing NFs according to locality attribute of each service-providing NF. Each locality attribute comprises structured values of location information of its service-providing NF. The method comprises obtaining a request from a service-requesting NF for one of the service-providing NFs. The request specifies a preferred locality of the requested service-providing NF. The preferred locality indicates, in terms of structured values of location information, geographical location where the service-requesting NF is deployed. The method comprises identifying, out of the service-providing NFs, that service-providing NF which has a locality attribute that best matches the preferred locality, whereby the service-providing NF closest to the geographical location where the service-requesting NF is deployed is identified. The method comprises providing a response to the service-requesting NF. The response comprises the locality attribute of the identified service-providing NF, thereby enabling discovery of the service-providing NF.

Implemented is a mechanism in which in a case where a communication device is leased from a certain operator to another operator, a permission for priority utilization of a frequency band does not need to be newly re-obtained.

A communication control device of the present disclosure includes: a first reception unit that receives a registration update request to update operator information about an operator who operates a communication device permitted to perform priority utilization of a frequency band, from a first operator to a second operator; and a management unit that, on the basis of the registration update request, updates the operator information about an operator who operates the communication device, from the first operator to the second operator, and maintains the permission for priority utilization of the frequency band by the communication device.

Session Communication Proxies (SCPs) generate SCP status information and/or SCP location information. A source network function selects one of the SCPs based on the SCP status information and/or the SCP location information. The source network function transfers data to the selected one of the SCPs. The selected one of the SCPs receives the data, selects a target network function, and transfers the data to the target network function. In some examples, a Network Repository Function (NRF) prioritizes the SCPs based on the SCP status information and/or the SCP location information, and the source network function selects the one of the SCPs based on the SCP prioritization.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). According to a method of the disclosure, an element management system (EMS) may perform a report on an error of a base station based on base station performance statistics, and an administrator may effectively manage the base station according thereto. According to an embodiment of the disclosure, a method of EMS is provided. The method comprises: receiving, from a plurality of base stations, first base station performance statistics information including at least one of a number of times of radio resource control (RRC) connection establishment attempts and a number of times of RRC connection establishment successes; identifying second base station performance statistics information, based on the first base station performance statistics information; identifying at least one first base station among the plurality of base stations, based on the second base station performance statistics information; identifying whether at least one second base station is detected from among the base stations other than the at least one first base station among the plurality of base stations, based on the second base station performance statistics information; and based on the at least one second base station being detected, transmitting an alarm message for the at least one second base station.

An in-vehicle navigation apparatus with a handsfree function establishes a Bluetooth communication link with a cellular phone. When receiving from the cellular phone outgoing call history data and incoming call history data, which were stored in the cellular phone before establishing the Bluetooth communication link, the in-vehicle navigation apparatus stores, in a work memory, the received outgoing call history data and the received incoming call history data, equally to, of the navigation apparatus itself, outgoing call history data and incoming call history data. An outgoing call operation then becomes possible using outgoing call history data and incoming call history data, which are stored in the work memory.
