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 |
20140204929 | METHOD AND APPARATUS FOR CONTROLLING WIRELESS LAN ACCESS POINT SELECTION OF USER EQUIPMENT IN WIRELESS COMMUNICATION SYSTEM - Methods and apparatus are provided for controlling Wireless Local Area Network (WLAN) selection in a wireless communication system. Information on a limitation of managed objects, indicating whether to allow reception of a WLAN selection policy from a roaming network, is received. It is determined whether a User Equipment (UE) exists in the roaming network. It is determined whether to receive the WLAN selection policy from the roaming network based on the information on the limitation of the managed objects, when the UE exists in the roaming network. The WLAN selection policy is received from the roaming network, when it is determined that the WLAN selection policy is to be received from the roaming network. A WLAN is selected according to a policy set for the UE, when it is determined that the WLAN selection policy is not to be received from the roaming network. | 07-24-2014 |
20140207960 | APPARATUS AND METHOD FOR REDUCING TRANSMISSION DELAY OF HTTP PROTOCOL AND PROCESSING LOAD OF HTTP SERVER IN WIRELESS COMMUNICATIONS NETWORK - A method and apparatus for managing and controlling wireless connection of a HyperText Transfer Protocol (HTTP) proxy device in a wireless communication network are provided. The method includes receiving one of information indicating a wireless connection deactivation of an HTTP client performing HTTP communication and information indicating a change in an Internet Protocol (IP) address of the HTTP client from a predetermined node of the wireless communication network; and deactivating a connection with an HTTP server if the received information indicates the wireless connection deactivation of an HTTP client performing the HTTP communication; and maintaining a connection with an HTTP server if the received information indicates the change in the Internet Protocol (IP) address of the HTTP client. | 07-24-2014 |
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.
