In mobile communication system, can communicate whenever and wherever possible in order to make mobile communication terminal, need operate and guarantee by constantly carrying out mobile management between this mobile communication terminal and fixing mobile communication network device.Wherein, the mobile communication network device of participation mobile management operation comprises base station, exchange of management equipment and location information management equipment etc.And mobile management operation generally comprises: the mobile communication terminal that a) is in idle condition under the triggering in incident or cycle, mutual by with mobile communications network, the location registers operation of the own location status information of registration in the information management apparatus of position; B) mobile communication terminal by being in connection status and mobile communications network is constantly mutual, upgrade base station transceiver or the wireless-access mode or the wireless system of its accessing mobile communication network, and in the relevant device of mobile communications network, upgrade the handover operation of its positional information and link information.
As everyone knows, in present mobile communication system, no matter which kind of environment mobile communication terminal is in, and the mobile management operation in this system is all independently carried out at single mobile communication terminal.That is to say that mobile communication terminal separately and carry out location registers operation and handover operation between mobile communications network.But,, such as automobile, train, steamer and aircraft, or in the environment such as self-organizing network, have that a large amount of mobile communication terminals is whole to be moved, and these mobile communication terminals all are quasi-static each other at movement environment.If the mobile communication terminal in this whole mobile environment independently carries out the mobile management operation respectively, not only can cause the increase of resource waste and mobile communication terminal power consumption, and, when mobile communication terminal is concentrated when carrying out these operations, the Network Management operational ton is increased severely temporarily, cause network congestion.
As a technology that addresses this problem, the patent application WO02/41659 of international publication has for example proposed a kind of location registering method and trunking of mobile communication terminal.In this patent application, by the trunking that is installed in the mobile unit sign that is in all mobile communication terminals in this mobile unit is sent to mobile communications network with the sign of trunking, make it possible to the renewal that the location status information of these mobile communication terminals is concentrated.Be specially, when mobile communication terminal entered this mobile unit, the trunking in this mobile unit sends set up the subordinate relation request, and listens to the broadcasting of mobile communications network and trunking simultaneously; Then, when the location registration area under the relaying equipment changes, trunking is in the location information management equipment of mobile communications network, register the information that this mobile communication terminal is subordinated to this trunking simultaneously and represent mobile communication terminal contained in it registration location state information respectively, this information has pointed out to change the affiliated location registration area of back mobile communication terminal.
Wherein, the disclosed trunking of this patent application is arranged in the mobile unit that moves with certain speed, and the composition structure of this trunking comprises as shown in Figure 1:
Transmission/receiving element, be used for respectively and the mobile communication terminal of outside mobile communications network and mobile unit between carry out the transmission and the reception of signal;
Mobile communication terminal sign memory cell, be used for transmissions/receiving element from mobile communication terminal receive comprise the mobile communication terminal sign set up the subordinate relation request time, the mobile communication terminal of receiving identified store;

1, mobile communication terminal enters whole mobile environment, after detecting trunking, sends the subordinate relation request of setting up to trunking immediately.Trunking is after receiving this request, and this subordinate relation request of registration does not send this request immediately to mobile communications network in this equipment.But wait until when after this trunking detects the location registration area variation, just the mobile communication terminal of all registrations during this sign, trunking sign and location status information are issued mobile communications network, set up subordinate relation simultaneously and carry out the location registers operation.But it can't average out between promptness and high efficiency, when many mobile communication terminals enter whole mobile environment simultaneously, it is excessive that this mode will cause trunking to issue the message blocks of mobile communications network, the Network Management operational ton is increased severely temporarily, increase the processing burden of mobile communications network; And when seldom mobile communication terminal disperseed to enter whole mobile environment, this mode will cause the low of location registers operating efficiency, had run counter to the original intention of the location registers operation of concentrating.
2, after mobile communication terminal and trunking are set up subordinate relation, because mobile communication terminal still directly communicates by mobile communications network, therefore the mobile communication terminal broadcasting that not only will listen to trunking, also to constantly listen to the broadcasting of mobile communications network simultaneously and upgrade its location status information, this has just increased the processing burden of mobile communication terminal, has wasted it and has handled resource and increased its power consumption.
3, mobile communication terminal is after setting up subordinate relation with trunking, because what preserve in the information management apparatus of position is the tabulation of each mobile communication terminal and location registration area information separately, therefore, in the location registration area information of still needing when the position is upgraded carrying out independently updated each mobile communication terminal and trunking, this has increased the processing burden of mobile communications network and has wasted its resource.Such as, in the information management apparatus of position, the scheme that this patent has is not managed subordinate relation, and each mobile communication terminal upgrades the position respectively by trunking, causes system resource waste; Additional another information list of the scheme that has is managed subordinate relation, causes the complexity of the waste and the management of storage resources.
4, in whole mobile environment, be in the switching of the mobile communication terminal of connection status, if still adopt the conventional method in the current mobile communication system, be that mobile communication terminal equipment room independent and mobile communications network carries out handover operation, not only can cause the low of the increase of valuable resource waste, mobile communication terminal power consumption and mobile management efficient, and concentrate when carrying out these operations when mobile communication terminal, the Network Management operational ton is increased severely temporarily, cause network congestion.
