Abstract:
A method and an apparatus for feedback based on information transmitted between base stations (or base stations) through cooperative communication are provided. The method includes receiving, from the second base station, a first message for requesting a channel state information (CSI) report, and transmitting, to the second base station, a second message including the CSI report, based on the first message. The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE).
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). 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.Methods and apparatuses provide a service to user equipment through a dedicated core network. In one method, a base station, also referred to as eNB, receives a non-access stratum (NAS) message from user equipment (UE), and transmits a first initial UE message having the NAS message to a first mobility management entity (MME). Also, the base station receives a redirection request message having the NAS message from the first MME, and transmits a second initial UE message having the NAS message to a second MME. In another method, the MME receives the first initial UE message having the NAS message from the base station, and transmits the redirection request message having the NAS message when the MME fails to support a dedicated core network according to UE usage type information. If the redirection request message is transmitted, a second initial UE message having the NAS message is transmitted to a dedicated MME.
Abstract:
The purpose of the present disclosure is to use a mobile communication service by changing a terminal, and a terminal changing method according to the present disclosure comprises the steps of: detecting a terminal change request for using the mobile communication service, by changing a terminal to a second terminal; receiving terminal information of the second terminal from the second terminal in response to the request; and transmitting a terminal change request message including the received terminal information of the second terminal.
Abstract:
This disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate after a 4G communication system such as LTE. In one embodiment for paging a terminal, a base station identifies information on a coverage enhancement (CE) level of the terminal and transmits a message including the information on the CE level of the terminal to a mobility management entity (MME). When a paging message including the information on the CE level from the MME is received, the base station transmits a paging signal to the terminal, based on the CE level of the terminal.
Abstract:
A terminal and a method for the terminal to attach to a network in a wireless communication system are provided. The method includes selecting a service provider based on service provider information received from a base station; identifying if the selected service provider operates an isolated evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN) operation for public safety (IOPS) network; if the selected service provider operates the IOPS network, selecting authentication information to attach to the IOPS network from a subscriber identification storage unit; and accessing the IOPS network using the selected authentication information.
Abstract:
The present invention relates to a method and apparatus for eliminating and improving issues that can occur during the execution of the cooperation between base stations in a wireless communication. The method comprises the steps of: identifying whether at least one cell among cells belonging to a counterpart base station is located in the vicinity of a base station; determining, according to a result of the identifying, whether to include information on a neighboring cell in a base station-related message; and transferring the base station-related message to the counterpart base station according to the determination.
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). 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. The method and apparatus provide information on traffic of a user equipment in a mobile communication system to an operator's network or to a third server. An operator can operate a proxy and may inspect and control a hypertext transfer protocol over secured layer (HTTPS) traffic through the proxy to collect HTTPS traffic relevant information.
Abstract:
An embodiment of the present invention relates to a method and an apparatus for collecting authentication information of a terminal while reducing the load of a home subscriber server (HSS). The present invention provides a method and an apparatus for transmitting a location registration message of a terminal for convenience of the mobility management node selection by a base station, a method and an apparatus for the mobility management node selection by a base station, and a method and an apparatus for collecting authentication information by the mobility management node. According to the embodiment of the present invention, it is possible to obtain authentication information of the terminal while reducing the load of the HSS.
Abstract:
The present invention relates to a communication technology and system converging the fifth generation (5G) communication system for supporting a data rate higher than that of the 4G system with the IoT technology. Further, the present invention is applicable to the intelligent services based on the 5G communication and IoT technologies (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety services). In more detail, a broadcast resource congestion control method of a multi-cell/multicast coordination entity (MCE) includes receiving a message including multimedia broadcast and multicast service (MBMS) congestion information from a base station, selecting an MBMS service to be controlled based on the MBMS congestion information, and transmitting a scheduling message including first control information related to the selected MBMS service to the base station.
