Also, the terms " part, "" module," and " module ", etc. in the specification mean a unit for processing at least one function or operation and may be implemented by hardware or software or a combination of hardware and software have. Also, the terms " a or ", "one "," the ", and the like are synonyms in the context of describing the invention (particularly in the context of the following claims) May be used in a sense including both singular and plural, unless the context clearly dictates otherwise.
The specific terms used in the embodiments of the present invention are provided to facilitate understanding of the present invention, and the use of such specific terms may be changed into other forms without departing from the technical idea of the present invention.
The following techniques include code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and the like. It can be used in various radio access systems. CDMA may be implemented in radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. The TDMA may be implemented in a wireless technology such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE). OFDMA may be implemented in a wireless technology such as IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, Evolved UTRA (E-UTRA). UTRA is part of the Universal Mobile Telecommunications System (UMTS). 3rd Generation Partnership Project (3GPP) long term evolution (LTE) is part of an Evolved UMTS (E-UMTS) using E-UTRA, and employs OFDMA in downlink and SC-FDMA in uplink. LTE-A (Advanced) is the evolution of 3GPP LTE.
For clarity of description, 3GPP LTE / LTE-A is mainly described, but the technical idea of the present invention is not limited thereto.
1 is a diagram schematically showing an E-UMTS network structure as an example of a mobile communication system to which the present invention can be applied. The Evolved Universal Mobile Telecommunications System (E-UMTS) system evolved from the existing Universal Mobile Telecommunications System (UMTS), and is currently undergoing basic standardization work in 3GPP. In general, E-UMTS may be referred to as an LTE (Long Term Evolution) system.
Referring to FIG. 1, an E-UMTS includes a user equipment (UE), an evolved universal terrestrial radio access network (E-UTRAN), and an evolved packet core (epc).
E-UTRAN is an evolved network from the existing UTRAN. The E-UTRAN is composed of base stations (eNBs), and each base station is connected through an X2 interface. The base station is connected to the terminal through the air interface, and is connected to the Evolved Packet Core (EPC) through the S1 interface.
One or more cells exist in one base station. The cell is set to one of the bandwidths of 1.25, 2.5, 5, 10, 15, 20Mhz and the like to provide downlink or uplink transmission service to a plurality of UEs. Different cells may be configured to provide different bandwidths. The base station controls data transmission and reception for a plurality of terminals. The base station transmits downlink scheduling information to downlink (DL) data, and transmits the downlink scheduling information to the corresponding terminal in a time / frequency region, a coding, a data size, a Hybrid Automatic Repeat and ReQuest (HARQ) Information. Also, the base station transmits uplink scheduling information to uplink (UL) data to the corresponding mobile station to notify the time / frequency region, coding, data size, and hybrid automatic retransmission request related information that the mobile station can use. An interface for transmitting user traffic or control traffic may be used between base stations.
EPC is the core network (CN) of the E-UMTS, an evolution of the GPRS core network. EPC is an ALL-IP network divided into Control Plane and User Plane.
EPC includes Mobility Management Entity (MME), Serving-Gateway (S-GW), Packet Data Network-Gateway (PDN-GW), and Home Subscriber Server (HSS). The MME has information about the access information of the terminal or the capability of the terminal, and this information is mainly used for mobility management of the terminal. The S-GW is a gateway having an E-UTRAN as an end point, and the PDN-GW is a gateway having a PDN (Packet Data Network) as an end point. HSS is a central database (DB) with a user profile that provides the MME with user credentials and user profiles.
2 is a diagram showing a control plane and a user plane structure of a radio interface protocol between a UE and an E-UTRAN based on the 3GPP radio access network standard. The control plane refers to a path through which control messages used by a UE and a network are transferred. The user plane means a path through which data generated in the application layer, for example, voice data or Internet packet data, is transmitted.
The physical layer as the first layer provides an information transfer service to an upper layer using a physical channel. The physical layer is connected to a medium access control layer (upper layer) through a transport channel. Data moves between the medium access control layer and the physical layer through the transport channel. Data is transferred between the transmitting side and the receiving side physical layer through the physical channel. The physical channel utilizes time and frequency as radio resources. Specifically, the physical channel is modulated in an OFDMA (Orthogonal Frequency Division Multiple Access) scheme in a downlink, and is modulated in an SC-FDMA (Single Carrier Frequency Division Multiple Access) scheme in an uplink.
The Medium Access Control (MAC) layer of the second layer provides a service to a radio link control (RLC) layer, which is an upper layer, through a logical channel. The RLC layer of the second layer supports reliable data transmission. The function of the RLC layer may be implemented as a functional block in the MAC. The Packet Data Convergence Protocol (PDCP) layer of the second layer performs a header compression function to reduce unnecessary control information in order to efficiently transmit IP packets such as IPv4 and IPv6 in a wireless interface with a narrow bandwidth.
The Radio Resource Control (RRC) layer located at the bottom of the third layer is defined only in the control plane. The RRC layer is responsible for the control of logical channels, transport channels and physical channels in connection with the configuration, re-configuration and release of radio bearers (RBs). The radio bearer refers to a service provided by the second layer for data transmission between the terminal and the network. To this end, the terminal and the RRC layer of the network exchange RRC messages with each other. If there is an RRC connection (RRC Connected) between the UE and the RRC layer of the network, the UE is in the RRC Connected Mode, otherwise it is in the RRC Idle Mode. The Non-Access Stratum (NAS) layer at the top of the RRC layer performs functions such as session management and mobility management.
One cell constituting the base station eNB is set to one of the bandwidths of 1.25, 2.5, 5, 10, 15, 20Mhz and the like to provide a downlink or uplink transmission service to a plurality of terminals. Different cells may be configured to provide different bandwidths.
A downlink transmission channel for transmitting data from a network to a terminal includes a BCH (Broadcast Channel) for transmitting system information, a PCH (Paging Channel) for transmitting a paging message, a downlink SCH (Shared Channel) for transmitting user traffic or control messages, have. In case of a traffic or control message of a downlink multicast or broadcast service, it may be transmitted through a downlink SCH, or may be transmitted via a separate downlink multicast channel (MCH). Meanwhile, the uplink transmission channel for transmitting data from the UE to the network includes a random access channel (RACH) for transmitting an initial control message and an uplink SCH (shared channel) for transmitting user traffic or control messages. A logical channel mapped to a transport channel is a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH) Traffic Channel).

If the terminal 310 fails to access the target eNB during the handover start timer period, that is, until the timer expires, the terminal 310 returns to the source base station. This handover failure may occur due to an MME rejection, random access failure, or the like.

Meanwhile, since the terminal 310 is equipped with a global positioning system (GPS) module, the terminal 310 may receive a GPS signal and check the position of the terminal 310 using the received GPS signal. However, if the terminal 310 does not have a GPS module or if the GPS signal is weak and the location of the terminal 310 is not determined even when the GPS module is mounted, only the quality information except the location information is provided.

Cell-ID is a technique for assigning a location-specific ID to each base station and, if the terminal is registered in the base station, matches the cell ID to obtain a location of the terminal through the location of the base station. The ECID technique is a method of improving accuracy by adding distance information between the base station and the terminal to the Cell ID technique. In this case, the distance information refers to a value excluding a response processing time in a terminal from a time when a base station requests a response to the terminal and a time when the base station receives a response from the terminal (Round Trip Time RTT). And,
The OTDOA technique is a technique in which a terminal measures a delay time of a signal received from each cell and reports it to a serving cell, and the serving cell measures a position of the corresponding terminal using the reported delay times.
