The method includes sending, when an attach request from an MTC device is received by a Mobility Management Entity (MME), an attach report to a Home Subscriber Server (HSS), starting, upon reception of the attach report by the HSS, a timer lasting for a preset time duration, counting the number of MTC devices requesting attachment and the number of already attached MTC devices during the preset time duration, determining, upon expiration of the timer, by the HSS, an Access Point Name-Aggregate Maximum Bit Rate (APN-AMBR) in consideration of a sum of the counted number of MTC devices requesting attachment during the preset time duration and the counted number of already attached MTC devices, and sending, by the HSS, the determined APN-ABMR to the MME. | 08-16-2012 |
20120258766 | METHOD AND APPARATUS FOR CONTROLLING INTER-PLMN HANDOVER TO CSG CELL - A method and apparatus for controlling inter-PLMN handover based on CSG lists of equivalent PLMNs is provided. A method for receiving subscriber information of a terminal at a Mobility Management Entity (MME) includes transmitting an update location request message for the terminal to a Home Subscriber Server (HSS), and receiving an update location acknowledgement message with the subscriber information of the terminal from the HSS, wherein the update location request message comprises a list of equivalent Public Land Mobile Networks (PLMNs) among which the MME supports inter-PLMN handover of the terminal. The method and apparatus for controlling inter-plan handover to a CSG cell according to the present invention is characterized in that a control apparatus of a core network acquires the allowed CSG lists for determining a User Equipments (UEs) capability of access to a CSG cell and determines whether to permit inter-PLMN handover based on the allowed CSG lists. | 10-11-2012 |
20130121213 | DATA ACQUISITION METHOD AND APPARATUS FOR WIRELESS COMMUNICATION SYSTEM - A method and a terminal for acquiring information on the media supported by an emergency center to provide the terminal with the emergency call service using non-voice media as well voice media are provided. A method includes receiving information on media supported by an Internet Protocol (IP) Multimedia Subsystem (IMS) from a server, storing the information on the media supported by the IMS, and transmitting a signal to a Public Safety Answering Point (PSAP) based on the information on the media supported by the IMS and the terminal. The emergency call processing method of the present invention allows only the terminal capable of NOVES to perform the media information acquisition procedure, thereby avoiding overhead caused by media acquisition attempts of a large number of terminal. | 05-16-2013 |
20130143610 | APPARATUS AND METHOD FOR DELIVERING SHORT MESSAGE SERVICE EFFICIENTLY IN WIRELESS COMMUNICATION SYSTEM - A Short Message Service (SMS) delivery method and apparatus is provided for delivering an SMS message efficiently by selecting a network domain to attach to according to the service provided to a Mobile Station (MS) by the mobile operator network. An SMS delivery method of the present invention includes receiving, at a network node, an Attach/Routing Area Update (RAU) Request message including a parameter indicating an attach/update type and SMS-only service, and transmitting, when SMS in a Serving General Packet Radio Service (GPRS) Support Node (SGSN) is supported at the core network node, to the mobile station an Attach Accept message including a parameter indicating that SMS in SGSN is supported. The SMS delivery method of the present invention is capable of delivering SMS message efficiently in the wireless communication system. | 06-06-2013 |
20130150029 | APPARATUS AND METHOD FOR DELIVERING SHORT MESSAGE SERVICE EFFICIENTLY IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for controlling Short Message Service (SMS) delivery to a User Equipment (UE) over a Packet-Switched (PS) network without involvement of any Circuit Switched (CS) network node are provided. The method includes receiving subscriber information of a terminal from a Home Subscriber Server (HSS), determining whether the MME supports short message delivery over a Packet-Switched (PS) network, and transmitting, when the MME supports the short message delivery over the PS network, a registration request message including information for routing the short message to the MME to the HSS. The SMS delivery method and apparatus is capable of delivering the SMS message to the UE over the PS network without involvement of the CS network nodes, thereby negating the necessity of CS network nodes for supporting SMS service, resulting in reduction of maintenance and management costs. | 06-13-2013 |
20140029420 | METHOD AND APPARATUS FOR TRAFFIC OFFLOADING BASED ON CONGESTION IN WIRELESS COMMUNICATION SYSTEM - A method that can increase network performance and user perceived service quality by allocating more radio resources to user data through a non-3GPP Access Network (AN) in a wireless communication system such as LTE is provided. Use of a 3GPP AN or a non-3GPP AN may be set in a user equipment or set according to a policy received from a policy server such as ANDSF. A scheme for dynamically updating and applying a policy according to user and AN conditions is provided. The scheme provides two approaches for determining whether to apply a policy according to user and the AN conditions. | 01-30-2014 |
20140038608 | METHOD AND APPARATUS FOR ADJUSTING MOBILITY PARAMETER - A mobility parameter adjustment method and apparatus for use in a wireless communication system is provided. The mobility parameter adjustment method of a base station includes receiving connection failure information from a terminal, and adjusting a mobility adjustment parameter based on the connection failure information. The mobility parameter adjustment method and apparatus of the present disclosure is capable of adjusting mobility parameter efficiently so as to improve the mobility robustness of the wireless communication system and User Equipment (UE). | 02-06-2014 |
20140254367 | METHOD AND APPARATUS FOR CONTROLLING CONGESTION STATUS OF MOBILE COMMUNICATION NETWORK - A method and an apparatus determining a policy by a Policy and Charging Rules Function (PCRF) is provided. The method of determining a policy by the PCRF includes receiving congestion status information of a network from a base station, transmitting the congestion status information to a content server, receiving a parameter for adjusting traffic transmission characteristics from the content server, and determining a policy related to traffic transmission based on the parameter. | 09-11-2014 |
