Abstract:
A method and apparatus for avoiding a collision of an uplink preamble using a cell identifier. In a case of installing a new small-sized base station in a mobile communication system, the method and apparatus may set a code parameter, a time parameter, and a frequency parameter, differently from a neighboring small-sized base station using the cell identifier even when dedicatedly using a preamble in a contention-free scheme to avoid a collision of the preamble, so that a random access preamble may be managed without occurrence of the collision with the neighboring small-sized base stations.
Abstract:
The inventive concept relates to a health care system, and more particularly, to a health care server of the health care system and a method of operating the same. The health care server includes a symptom collection module collecting clinical information of patient from a hospital server and health information of patient from an individual health record server; an alarm and reaction rule management module generating an alarm rule on the basis of the clinical information and the health information; and an alarm generation module monitoring the health information or the clinical information and generating an alarm when the monitored health information or the clinical information corresponding to the alarm rule. The health care server can provide a different alarm service to a patient having a different health state with reference to clinical information and health information of each patient.

In the optimization system, a base station may include a measured data collecting unit to collect wireless environment data measured by a terminal included in a cell, a threshold managing unit to manage a threshold value associated with a radio link failure in a wireless section, an analyzing unit to manage a variable associated with a radio link failure, and to analyze a cause of the radio link failure, and a parameter changing unit to change a parameter value based on an analysis result of the analyzing unit.
Abstract:
A physical examination method using a mobile terminal, and a gateway and a mobile terminal for physical examination are provided. The physical examination method using a mobile terminal may include: receiving, at a physical measurement gateway, information on a subject and information on a physical measurement device to be used by the subject through the mobile terminal; and receiving, at the physical measurement gateway, physical information on the subject measured by the physical measurement device, transmitting the physical information to a health management server, receiving physical examination results, obtained based on the transmitted physical information, from the health management server, and providing the physical examination results to the mobile terminal of the subject. Thus, a patient who has limited mobility can easily undergo a physical examination without accessing the physical measurement gateway, thereby constructing a convenient U-health environment.

Abstract:
Provided is a method and apparatus for avoiding a collision of a preamble in a base station. When a new base station is installed in a mobile communication system and in this instance, an exclusive preamble using a contention-free scheme is employed to avoid a preamble collision, at least one of a code parameter, a time parameter, and a frequency parameter used in a preamble of the new base station may be set to be different from a code parameter, a time parameter, and a frequency parameter used in a preamble of a neighboring cell, whereby it is possible to manage a random access preamble without causing a collision between cells.
