Provided are a battery cell and a battery module including the same, and more particularly, the battery cell can secure safety thereof, by forming an exhaust part in a predetermined region of a sealing part to have a sealing member thicker than the other region of the sealing part so that the exhaust part has relatively weaker adhesive strength than the sealing part not containing the exhaust part, and thus, the adhesive state of the exhaust part is broken when high pressure occurs within the cell due to overheat conditions such as overcharging or inner short circuits to cause a case of the cell to swell, thereby discharging out the substances within a pouch type secondary cell.

The invention relates to a communication method for a terminal, which enables the transmission of information to a base station and which comprises the steps of: attempting random access to a first base station; creating an rlf-report including one or more pieces of information associated with the random access in the event the random access fails; connecting to one base station from among base stations including the first base station; and transmitting the rlf-report to the connected base station. According to one embodiment of the present invention, a communication method for a base station, which enables information to be received from a terminal, comprises the steps of: connecting to the terminal; and receiving an rlf-report including one or more pieces of information associated with the random access from the connected terminal when a previously-performed random access in the terminal has failed. According to the embodiments of the present invention, information including channel information is transmitted to a base station to which a terminal is initially connected even when the terminal has failed in performing random access thereto, to thus enable the efficient transmission of information, and the base station may control scheduling or the like in accordance with the information reported by the terminal, thereby enabling efficient communication.

The present invention relates to a method and apparatus for measuring a signal. According to one embodiment of the present invention, a signal measuring method may comprise the steps of: determining whether or not a current subframe corresponds to a measurement period; measuring a serving cell signal when the current subframe corresponds to the measurement period; determining whether a current measurement mode is a normal scan mode or a short scan mode in which a serving cell signal is more frequently measured than in the normal scan mode; determining whether or not the measured serving cell signal is less than a preset low signal threshold value when the current measurement mode is the normal scan mode; and changing the current measurement mode to the short scan mode when the measured serving cell signal is less than the low signal threshold value. According to one embodiment of the present invention, a system signal measuring method and apparatus which can quickly reflect the surrounding environment while efficiently using power is provided.

According to an embodiment of the present invention, a system access method for a user equipment performing machine-to-machine (M2M) communication with a system may include: awaiting, when the user equipment detects a need for system access, reception of access delay information from a base station for a preset delay information wait time; obtaining, when access delay information is received from the base station within the delay information wait time, an access delay time from the access delay information; and awaiting expiration of the access delay time while not attempting system access. Hence, system access attempts made by many M2M user equipments can be efficiently handled in the present invention.
