Provided is a method of managing mobility of a user equipment. The method includes: establishing by a first base station a communication with the user equipment; transmitting by the first base station a Coordinated Multiple Point (CoMP) addition request to a second base station; establishing by the first and second base stations a CoMP communication with the user equipment according to the CoMP addition request; transmitting by the first base station an anchor cell change request to the second base station; and operating the second base station as an anchor cell of the CoMP communication according to the anchor cell switch request.

A method for paging optimization in a communication system having one or more base stations and one or more mobile stations within a paging target cell, includes detecting a hybrid base station supporting a hybrid cell from the one or more base stations; and determining whether or not one or more mobile stations registered in the hybrid cell include only closed subscriber group (CSG) members, and defining an operating state of the hybrid base station based on the determination result. The method further includes determining whether or not each of the one or more base stations is included in paging targets based on the operating state of the hybrid base station.

There is provided mobile communication terminals and a method of updating software of the same. A method of updating software of mobile communication terminals includes, when software providers provide one or more pieces of update software for updating software of mobile communication terminals, creating a broadcast message including information about each piece of the update software, broadcasting the broadcast message to each of the mobile communication terminals over a wireless communication network, and, when a request to update the software of the mobile communication terminals is received from each of the mobile communication terminals that have received the broadcast message, providing a piece of corresponding update software to each of the corresponding mobile communication terminals over the wireless communication network. Accordingly, mobile communication terminals can be prevented from accessing a network unnecessarily, and ineffective use of wireless resources can be reduced.

Disclosed is a method for controlling access of subscribers of a gateway in a communication system supporting a femto cell, the method including: by user equipment (UE), receiving a first access request message, which makes a request to access a femto base station (BS), from the femto BS; directly acquiring a business subscriber database (DB), which includes a list of UE admittable to access the femto BS, from a DB module; and determining whether to admit the access of the UE on the basis of the business subscriber DB, wherein the determining whether to admit the access of the UE includes admitting the access of the UE if a user equipment identifier (UE ID) for identifying the UE is included in the list of UE.
摘要:
The present invention relates to a stationary user detecting system and method and a call admission control method using the same in a wireless communication system. A plurality of base stations located in the wireless Internet system detect a stationary user at regular time intervals and maintain it by a predetermined number of cases for each terminal. Information on the maintained stationary user is recalculated with a stationary probability for each base station so as to be used for call admission control. Therefore, the terminal of the stationary user detected in the wireless Internet system is calculated with the stationary probability value, which is applied to the call admission control, thereby minimizing reservation of undesired resources.
