Abstract:
PURPOSE: A method for processing a call connection of an advanced mobile communication system RNC(Radio Network Controller) is provided to create and transmit a message to be transmitted to an upper or a lower layer of an SCCP(Signal Connection Control Part) by using call connection information and a hash value according to a kind of the message, thereby preventing collision between reference numbers in a No.7 SCCP layer. CONSTITUTION: If a message is transmitted from an upper layer of an SCCP(311-101), the SCCP creates an input number, and creates a hash value with the input number. The SCCP maps the created hash value with a lower primitive by a reference number, and transmits the value to a lower MTP(Message Transfer Part)(311-102). If the message is transmitted upward from the SCCP(311-103), the SCCP extracts a connection point and a reference number. The SCCP makes either of an 'up_ref' value and a 'dn_ref' value stored in call connection information(311-108) a reference number, and upward transmits the reference number to an AP(Application Protocol)(311-104). The call connection information(311-108) includes the reference numbers, and consists of information for performing primitive mapping between upper and lower layers.
Abstract:
PURPOSE: A start time point randomizing method of a subject terminal operation is provided to randomize operation time of a subject terminal. CONSTITUTION: A terminal(210) standby for standby time of an interval which is shorter than the operation time interval from a starting point of an operation time interval(250). The terminal determines a network device(220) is connected to the terminal(260). The terminal is connected to the network device according to the determination(261). The terminal transmits data to an application server(230) via the network device(270,271).

본 발명은 멀티 셀 환경에서의 신호간섭 개선방법에 관한 것으로, 서빙중인 홈셀에 통신품질 열화가 발생한 경우 이동단말로부터 송신되는 무선자원 측정결과 메시지를 서빙중인 홈셀을 통해 수신하고, 수신된 무선자원 측정결과 메시지로부터 간섭을 유발한 인접셀을 선택하고, 서빙중인 홈셀의 무선자원 형상과 동일한 무선자원이 상기 선택된 인접셀에서 할당 가능한지 여부에 따라, 신호간섭 개선 방식을 달리하여 홈셀과 인접셀간의 신호간섭을 개선하도록 함으로써 이동단말의 통신 품질을 향상시킬 수 있도록 한 것이다. 이동단말, 멀티 셀 환경, 신호간섭, 홈셀, 인접셀, 무선자원
Abstract:
An access control method in designated wireless access mode of a mobile communication system is provided to control wireless access mode of the mobile communication terminal by determining a traffic property by a base station, thereby reducing power consumption of the terminal. It is determined whether data receiving mode of a terminal(10) is converted into activation mode or inactivation mode. A message including a timing parameter is transmitted. The message is transmitted by an RNL(Radio Network Layer)(21) of a base station. The message is transmitted by a MAC(Medium Access Control) layer of the base station.
