Abstract

본 발명은, 기지국은 전체 트래픽 채널 자원중에서 일정한 수의 채널 자원을 핸드오프 전용의 채널로 보유하고 나머지 트래픽 채널 자원에 대해서는 일반호 요구시와 핸드오프 요구시 모두 할당할 수 있도록 관리하여 핸드오프가 빈번히 발생하는 환경에서 핸드오프 요구에 대한 호단절의 빈도를 효과적으로 줄이는 이동통신 시스팀의 트래픽 채널 관리방법을 제공하며, CDMA 이동통신 시스팀중 기지국에서 관리하는 n개의 트래픽 채널 자원중 일반호 및 핸드오프 요구시 할당하기 위해 i개의 트래픽 채널을 모두 할당했을때 핸드오프 요구시 할당할 수 있도록 j개의 트래픽 채널을 관리함으로써 일반호 요구시에는 i개중 1개를 할당하고, 핸드오프 요구시에는 i개의 채널중 할당되지 않은 트래픽 채널이 있을때 i개중에서 한개를 핸드오프용으로 할당하고, i개중에서 모두 할당하고 여유가 없을때는 j개의 핸드오프용 채널 중에서 한개를 핸드오프 요구에 대하여 할당한다.According to the present invention, a base station manages a predetermined number of channel resources among all traffic channel resources as a handoff-only channel and allocates the remaining traffic channel resources to both a general call request and a handoff request. It provides a traffic channel management method of mobile communication system which effectively reduces the frequency of call disconnection for handoff request in a frequently occurring environment, and requests general call and handoff among n traffic channel resources managed by base station among CDMA mobile communication systems. When all the i traffic channels are allocated for handoff request, the j traffic channels are managed so that they can be allocated when handoff requests are allocated. If you have an unallocated traffic channel, assign one out of i for handoff For all handset requests, all of i are allocated and one of j handoff channels is allocated to the handoff request when there is no room.

In a channel management method applied to a CDMA base station system having a packet router unit 26, a base station channel manager 2b, and a GPS receiver, the base station channel manager 2b is provided with respect to all channel resources managed by the base station. Perform a initialization operation, and a count (hereinafter referred to as a first count) for checking the number of traffic channels allocated for the general call and the handoff request, and only when there is no traffic channel resource for the general call for the handoff request A first step of respectively setting counts (hereinafter referred to as second counts) and initializing these counts to check the number of allocated traffic channels among j assignable traffic channels, and a mobile station (mobile subscriber) or less network (public network) A second step of checking whether the received request message is a normal call or a handoff call request when a call request message is received from the If the received message is a request message for a general call, the first count is increased by one, and the number of traffic channels already allocated exceeds the specified number. In this case, any channel among the available traffic channels that have not been allocated among the specific number of traffic channels is allocated, and when all the specific number of traffic channels are allocated, the service for the call request cannot be serviced. And a third step of notifying the mobile station or the network side of the status information, and if the received call request message is a handoff call, a channel which is not yet allocated and is idle in traffic channel resource specific number for a general call and a handoff call. Checks to see if there are any available channels that have not yet been allocated It assigns traffic channels to enable service for handoff call request, and checks the status of other specific number of traffic channels managed to allocate only when handoff occurs when all traffic of specific number of channels are allocated and in service. In step 4, the second count is increased by one, and when there is a channel that is not yet allocated among the specific number of handoff-only traffic channel resources compared to the specific number, an arbitrary traffic channel is allocated in duplicate.
