Abstract:
Disclosed are a method and an apparatus for transmitting and receiving measurement information in a mobile communication system. A terminal transmits a connection request message to a network and reports to the network, connection failure-related measurement information when a registered public land mobile network (RPLMN) included in a connection setup message received from the network corresponds to a pre-stored and selected public land mobile network (PLMN) and the connection failure-related measurement information stored with the selected PLMN is available.
Abstract:
Provided are a method and apparatus for dormant mode operation in a user equipment. During dormant mode, data transmission between the user equipment and network is suspended. For dormant mode operation, the user equipment determines whether to enter dormant mode, and sends, upon determining to enter dormant mode, a dormant mode entry message containing dormant mode time information to the network.
Abstract:
According to one embodiment of the present disclosure, the method by means of which a mobility management entity (MME) determines the communication mode of a terminal in a communication system includes the steps of: receiving, from the terminal, an access request including information on the position of the terminal; transmitting a message to a home subscriber server (HSS) on the basis of the received access request; receiving, from the HSS, specific position information for setting a first mode; comparing the information on the position of the terminal with the specific position information; and determining the communication mode of the terminal according to the result of the comparison. According to the present disclosure, the frequent transmission of small amounts of data can be supported in an efficient manner.
Abstract:
A method of measuring channel information using a terminal in a communication system, according to an embodiment of the present invention, includes the steps of: receiving channel measurement setup information from a base station; entering an idle mode in the state of communication with the base station; measuring information indicating according to the channel measurement setup information; and transmitting a signal including the measured information to the base station. In addition, a terminal for measuring channel information according to another embodiment of the present invention includes: a transmitting/receiving unit for receiving channel measurement setup information from a base station; and a control unit for controlling the terminal so that the terminal enters an idle mode in the state of communication with the base station and measures information indicating according to the channel measurement setup information, wherein the transmitting receiving unit transmits a signal including the measured information to the base station. According to an embodiment of the present invention, it is easier to identify a channel state by using an MDT measurement result by further reporting various pieces of information when measuring MDT. In addition, it is possible to perform a report on MDT measurement by using a terminal and thus the need for a drive test may be reduced.
