In this case, the base station controller 104 and the base transceiver station 100 cannot use the trunk lines T1 and T2 to perform normal interactive data reception and transmission
In other words, the base station controller 104 has discriminated that T1 and T2 are normal trunks, and therefore tries to perform load distribution related to the trunks T1 and T2, but the base transceiver station 100 can only perform load distribution related to the trunk T1, As a result, normal data transmission and reception cannot be performed through these two trunk lines
[0013] As a result, in the case where the connection states of the trunk lines T1 and T2 are managed using a conventional network state management device in the mobile wireless communication system, because the call connection for calling the terminal mobile unit may fail, or the original mobile unit and the terminal The call communication in use between the mobile units may be dropped, so the call quality of the entire mobile wireless communication system will be damaged

Embodiment Construction
[0027] Preferred embodiments of the present invention will now be described in detail, illustrations of which are shown in the accompanying drawings.
[0028] figure 2 The block diagram of is schematically showing the structure of the network status management system according to the preferred example of the present invention. refer to figure 2 , the network status management system according to the present invention comprises a base station controller 104, a trunk transmission device 102 connected with the base station controller 104, a base transceiver station 100, and a trunk line connected with the base transceiver station 100 A transmitting device 101, and a plurality of trunk lines T1 and T2 connected between the two trunk line transmitting devices 101 and 102. Each of the trunk transmitting devices 101 and 102 can detect the trunk connection state of the trunk lines T1 and T2, and can exchange the connection state information of each of the trunk lines T1 and T2 with ...

The network state management system and method in a mobile wireless communication system can prevent inconsistency of state information, line faults, abnormal load distribution functions, etc. occurring between multiple networks. A test packet is sent to the remote network through the normal trunk connection at predetermined time intervals, and the trunk identified as abnormal is forced into an abnormal state using the information contained in the test packet. Then, the trunk connection that has been discriminated and sent as an abnormal state is re-authenticated to determine whether it is in an abnormal state through another test process, and if the result of the discrimination is normal, it will be managed as a normal trunk connection. The network management status will be updated upon transmission of test packets for the trunk.
Description
technical field [0001] The invention relates to a network state management system and method in a mobile wireless communication system. More specifically, the present invention relates to a network state management system and a network state management method which utilize a system capable of coordinatingly managing the state of a network. In this network, base station controllers and base station transceiver subsystems are interconnected by multiple trunk lines in Code Division Multiple Access (CDMA) communication systems and Personal Communication Services (PCS) systems. Background technique [0002] The present invention refers to US applications US5509029A and US5544154A, the above publications are hereby incorporated by reference. [0003] Generally speaking, if a determined mobile unit user selects a terminal telephone number and sends a call signal to the mobile wireless communication system, the corresponding base transceiver station will receive the radio frequency...
