A method of a base station transmitting Multicast Broadcast Service (hereinafter referred to as MBS) includes transmitting MBS configuration information, including information about an MBS region which is a resource region to which MBS-related information is allocated and information about an MBS MAP, to a terminal and transmitting MBS data to the terminal through the MBS region. The information about the MBS region includes location information and a transmission parameter of the MBS region. The MBS MAP includes an MBS configuration information change indication which indicates whether the MBS configuration information is expected to change from first MBS configuration information to second MBS configuration information. MBS is effectively and persistently managed in a mobile wireless communication system supporting MBS.

In order to manage a neighbor list of neighboring base stations based on the location of a terminal communicating with a base station of a macrocell with femtocell deployments, the base station divides the macrocell in accordance with a predetermined standard of division, and generates a mobile neighbor advertisement message so as to periodically transmit the generated message to the terminal. At this time, the terminal identifies the current location thereof in the macrocell upon receipt of the pilot signals periodically transmitted from the base station of the macrocell. The terminal obtains information regarding the location of the terminal from the information regarding the femtocells deployed within the respective divided regions and information regarding macrocells neighboring the macrocell through using the mobile neighbor advertisement message to scan base stations.
摘要:
A method of supporting a security for a multicast communication is provided in a mobile station. The mobile station shares an MAK with a base station, derives a prekey based on a first parameter including the MAK, and derives a multicast security key including an MTEK based on a second parameter including the prekey, and decrypts a multicast traffic using the multicast security key.
摘要:
The present invention provides a method of a Base Station (BS) updating system information using a superframe structure in a wireless communication system, comprising transmitting a primary header including system scheduling information pertinent to an update of the system information and transmitting an updated secondary header. The system scheduling information comprises secondary header change state information indicating a change state of the updated secondary header, secondary header applying information indicating whether the secondary header change state information is applied to a current system, and a secondary header change indicator indicating the updated secondary header.
摘要:
A method of controlling power saving modes of a plurality of terminals joining in a group communication by a base station is provided. The base station establishes a group call connection with the plurality of terminals, and establishes a same power saving mode pattern for the plurality of terminals.
摘要:
A mobile terminal includes a front housing made of a light-transmitting material and provided with edge parts, at least one of which is rounded or bent to be inclined which causes optical illusions so as to provide visual mystique. A display unit is provided under the front housing. A circuit substrate is provided under the display unit. A rear housing is provided to accommodate the display unit and the circuit substrate together with the front housing. A middle housing is provided between the front housing and the rear housing. The middle housing includes a receipt part to accommodate the display unit, and boundary parts connecting the receipt part and edge parts of the middle housing and disposed under the edge parts of the front housing. The edge part of the middle housing is protruded from the boundary part of the middle housing in a horizontal direction.
摘要:
A circuit is configured to be operatively coupled to a plurality of memory devices arranged into one or more logical ranks. Each logical rank may correspond to a set of at least two physical ranks. The circuit is configured to be operatively coupled to a memory controller of a computer system to receive a logical rank refresh command. In response, the circuit can initiate a first refresh operation for one or more first physical ranks and then initiate a second refresh operation for one or more second physical ranks. The circuit can further include a memory location storing a refresh time (tRFC) value accessible by the memory controller and based at least in part on a calculated maximum amount of time for refreshing the logical rank.
