摘要:
An apparatus and a method for a terminal handover between systems using different Frequency Allocations (FAs) are provided. The method includes broadcasting an indication signal to inform of existence of the terminal in a coverage of a macro base station to which an indoor base station is registered; and when receiving a handover command message of the indoor base station, from the macro base station, performing a handover procedure to the indoor base station. The base station can efficiently utilize the control channel resource and the user terminal needs not to conduct the unnecessary scanning procedure. Thus, the time and the power required for the scanning can be spared.

A method for supporting a Peer-to-Peer (P2P) communication in a wireless communication system is provided. The method includes identifying whether a Mobile Station (MS) is in a wireless communication active state, a P2P active state, or a P2P previous active state, and transiting to the P2P active state if a P2P connection request occurs in the P2P previous active state and transiting to the P2P previous active state if a P2P communication termination occurs in the P2P active state.

A method and apparatus for managing a spam message in a messaging service are disclosed. When a user reports a message determined as a spam message, he may directly select a sharing level of his personal information in order to prevent a leakage of the personal information according to a sharing policy, reports the spam message by transmitting only a hash value of the spam message in order to prevent an increase in traffic. With respect to reported spam messages, a user can access a spam server to check an errononeously reported message through a sorting algorithm.

Negative active materials for rechargeable lithium batteries are provided. One negative active material includes a metal matrix, and an intermetallic compound including a Si active metal and an additive metal dispersed in the metal matrix. The additive metal may be Ca, Mg, Na, K, Sr, Rb, Ba, Cs, or a combination thereof. The metal matrix may comprise Cu and Al. The negative active material may comprise a X(aM-bSi)—Y(cCu-dAl) material, where X is from about 30 to about 70 wt %, Y is from about 30 to about 70 wt %, X+Y is 100 wt %, a+b is 100 wt %, a is from about 20 to 80 wt %, b is from about 20 to 80 wt %, c+d is 100 wt %, c is from about 80 to about 95 wt %, d is from about 5 to about 20 wt %, and M may be Ca, Mg, Na, K, Sr, Rb, Ba, Cs, or a combination thereof.
摘要:
A method and system for determining a communication mode in a communication system are provided. The system and method include determining whether a first MS and a second MS are located within a preset area where P2P communications are available, estimating a first expected performance that can be achieved when the first and second MSs operate in a cellular communication mode, estimating a second expected performance that can be achieved when the first and second MSs operate in a P2P communication mode if the first and second MSs are located within the predetermined area, and selecting one of the cellular communication mode and the P2P communication mode as a communication mode between the first and second MSs by comparing the first expected performance with the second expected performance.
摘要:
An apparatus and method for supporting Peer-to-Peer (P2P) communications in a broadband wireless communication system are provided. A frame used by the terminal in P2P communications includes a plurality of P2P contention channels overlapping with a region for cellular communications and at least one P2P dedicated channel allocated by a base station only for the P2P communications. The method includes establishing a P2P connection with a correspondent terminal through the at least one P2P dedicated channel, and exchanging P2P communication data with the correspondent terminal through at least one of the plurality of P2P contention channels.
