A paging method of a terminal is characterized by comprising the steps of: receiving, from a base station, both a local counter value for synchronization with the base station and a local ID that the base station has allocated to the terminal; synchronizing the base station and the counter using the local counter value so as to enter an idle state; and checking the local counter and a paging trigger message contained in the subframe corresponding to the local ID. According to the present invention, local IDs are each allocated to the respective multiple MTC terminals, and therefore trigger periods can be efficiently managed in a network. Further, the multiple MTC terminals can be grouped using the allocated local IDs, thus achieving advantages of an increased number of MTC terminals which can be managed in the network. | 06-19-2014 |

And, the congestion state information includes information about a congestion state of the ENB, and is included in a packet header transmitted from the UE. | 07-24-2014 |
20140235249 | MOBILE COMMUNICATION SYSTEM AND METHOD OF INFORMATION PROCESSING FOR IMPROVING USER EXPERIENCE IN THE MOBILE COMMUNICATION SYSTEM - The present invention relates to a method for processing information between mobile communication systems in order to prevent the degradation of user-experienced performance when different types of mobile communication networks are used. The method for processing information at user equipment (UE) to improve user-experienced performance of a mobile communication system includes performing a data communication through a first network and receiving, from a policy server, a routing policy including a validity condition which is information about a condition of designating a UE status for handover. The method further includes, in the handover, if a searched second network satisfies the validity condition, performing the data communication through the second network. Accordingly, a network for data transmission can be selected using a routing policy created in consideration of a UE status or a network status, thereby enhancing user-experienced performance. | 08-21-2014 |
20140235262 | METHOD AND APPARATUS FOR CONTROLLING SYSTEM OVERLOAD IN A WIRELESS COMMUNICATION SYSTEM - The present invention relates to a method for controlling system overload in a wireless communication system. The method comprises: a first step in which a mobility management entity (MME) that has received a tracking region update request message from a first terminal transmits a location update request message to a home subscriber server (HSS); a second step in which, if the HSS has determined that a system overload has occurred, the HSS sets MME-backoff time for preventing the transmission of a request message to the HSS, and transmits a location update rejection message including said MME-backoff time to the MME; and a third step in which the MME drives a backoff timer corresponding to said MME-backoff time and rejects a TAU update request message from a terminal received prior to the completion of the driving of the backoff timer. | 08-21-2014 |
20140254356 | METHOD AND APPARATUS FOR CONTROLLING TRAFFIC OF RADIO ACCESS NETWORK IN A WIRELESS COMMUNICATION SYSTEM - Provided is a method for controlling traffic of a Radio Access Network (RAN) in a wireless communication system. The method includes acquiring at least one of subscription class information of a User Equipment (UE) user and type information of an application or content; determining whether a congestion situation has occurred in the RAN; and controlling traffic for the UE based on the acquired information, if the congestion situation has occurred in the RAN. | 09-11-2014 |
20140307615 | Apparatus and Method for Transmitting/Receiving Multiuser Packet in a Mobile Communication System - An apparatus and method is provided for generating one packet with transmission data and transmitting the packet from an access network transceiver system (ANTS) to a plurality of access terminals (ATs) in a mobile communication system including the ATs and the ANTS which are capable of performing packet data communication with ATs located in coverage thereof. The method includes the steps of generating a medium access control (MAC) header including information on a receiving AT's address, a length and format for transmission data, generating a MAC payload, by consecutively connecting data units to be transmitted to the receiving AT, and generating a MAC trailer. The ANTS pads ‘0’ bits to the MAC header if a predetermined MAC size is greater than a sum of lengths of the MAC header, the MAC payload and the MAC trailer. | 10-16-2014 |
20140313889 | METHOD AND APPARATUS FOR CONTROLLING USER EQUIPMENT ACCESS IN MOBILE COMMUNICATION SYSTEM - A method for a Mobility Management Entity (MME) to control a connection of a User Equipment (UE) in a mobile communication system is provided. The method includes a first standby method including an MME in a wireless communication system that includes predicting an overload durating time when an overload duration time that is predicted, transmitting to an enhanced Node B (eNodeB) information on the reconnection method of the UE that is decided, wherein the plurality of reconnection methods represent methods for the UE attempting reconnection with the MME after a second standby time that is longer than the first standby time, and an MME reselection method for the UE attempting the reconnection with an MME which is different from the MME. | 10-23-2014 |
20140376512 | METHOD AND APPARATUS FOR SUPPORTING MOBILITY OF UE IN LOCAL NETWORK - The present invention relates to a method and apparatus for managing a Local IP Access (LIP A) connection in a local network system. The method of managing a LIP A connection of UE in a connected state according to an embodiment of the present invention includes the steps of: a source home base station for UE determining a handover of the UE; when the handover of the UE is determined, determining whether a target home base station is a Long Term Evolution (LTE) release 10 or a Pre Rel-11 HeNB; and when the target home base station is a Pre Rel-11 HeNB, disconnecting the LIP A connection of the UE. According to an embodiment of the present invention, the mobility of UE having a LIPA PDN connection can be efficiently controlled in a local network where a Rel-11 H(e)NB and a Pre Rel-11 H(e)NB exist together. | 12-25-2014 |
