Provided is an apparatus and method for setting up aquality-of-service (QoS) in a mobile communication system. A mobile terminal (MT) generates a resource reservation message including requested QoS information and packet filtering information for a predetermined service. A packet data service node (PDSN) stores the QoS information and the packet filtering information. Upon receiving packet data corresponding to the stored QoS information from the external network, the PDSN sends a request for a new QoS setup to the AN. An access network (AN) determines a granted QoS to be applied to a wireless session and sends a request for new QoS setup to the MT. If the MT grants the new QoS setup, the MT sends a response to the new QoS setup request from the MT to the PDSN via the AN.

Disclosed is a method of fabricating a PCB including an embedded passive chip, in which the passive chip is mounted on the PCB and an insulator is then laminated on the PCB, or in which a blind hole for receiving the passive chip is formed in the PCB and the passive chip is mounted in the blind hole.
摘要:
A method for controlling the hand-off of an MS (Mobile Station) for the home zone service in a mobile telecommunications system including a plurality of BTSs (Base Transceiver Stations), a BSC for controlling the BTSs, and an MSC (Mobile Switching Center) for connecting the BSC with a different BTS or network, comprising the steps of causing the MS to connect through the BTS with the BSC (Base Station Controller) by an outgoing or incoming call, causing the BSC to store the home zone list and the subscriber service class of the MS received from the MSC, and causing the BSC to perform the hand-off requested by the MS according to the home zone list and the subscriber service class. Thus, when the MS registered only in the fixed network, so as to be provided with communication services only in the home zone, travels through the other regions than the home zone, the BTS drops the presently connected call with an alert message. However, the MS registered both in the fixed and in the mobile network, so as to be provided with communication services both in the home zone and in the other regions, travels through the other regions, the BTS only sends an alert message to the MS without dropping the presently connected call. In this case, the BTS operator has discretion as to whether to send the alert message to the MS.

An apparatus and method for processing a call in a mobile communication system are provided. In the apparatus and method for processing a call in the mobile communication system, a base station sector at which a mobile station is located and a neighboring base station sector are designated as one call receiving zone when a mobile station transitions from a traffic state to a dormant state and paging is performed to a call receiving zone which is first designated when a call is received to the mobile station.
