Description
Technical field
The present invention relates to the cluster wireless communication technical field, the method for calling when being meant the operation of a kind of single station especially.
Background technology
Wireless trunking communication system, hereinafter to be referred as group system, be a kind of less expensive of growing up in recent years, command dispatching and communication system more flexibly, be widely used in units such as government bodies, energy traffic, airport harbour, industrial and mining enterprises, fire-fighting police, water conservancy and military affairs, to satisfy the needs of constituent parts intercommunication.
Usually in mobile communication system, for correct paging mobile subscriber, need the user to register to network, make network can follow the trail of the current present position of mobile subscriber district.When calling out arrival, network will be this mobile subscriber of the lane place of user's correspondence paging.In the prior art, position updating process is to be cooperated by logic between attaching position register (HLR), mobile services switching centre (the MSC)/Visited Location Registor entities such as (VLR) to finish.HLR record mobile subscriber's current location information and all customer data; The VLR record roams into the relevant user data by the mobile subscriber in this VLR control position district; MSC handles mobile subscriber's location registers process, with mobile subscriber's dialogue and with HLR, VLR interactive information.
Cause that the condition that the mobile subscriber takes place to upgrade the normal position is: roaming takes place and causes position change, the registration of timer-operated periodic location in mobile device start, mobile subscriber.Usually the start position is upgraded and is also claimed registration process or enrollment process.Periodic location update can keep not having for a long time the user of operation and getting in touch of network.Its process is: when starting shooting first, this user is by obtaining position district sign (LAI) from the system message of Cell Broadcast CB; To network registration, VLR distributes a Temporary Mobile Station Identity (TMSI) for it to the user by International Mobile Subscriber Identity (IMSI).When the mobile subscriber roamed, LAI was not equal to the LAI that self stores in the system message of this stylish Cell Broadcast CB, and the mobile subscriber will carry out the position by LAI+TMSI and upgrade, and new VLR is that it distributes new TMSI, and the user obtains new LAI by broadcast.After each position is upgraded, the residing new LAI of user will be notified to HLR, and HLR upgrades the LAI of this user's correspondence.
When the calling network mobile subscriber, network side can be determined the affiliated HLR of this user according to mobile subscriber number (MSISDN), and then the LAI that preserves among the acquisition HLR, and this paging is routed to the VLR and the MSC of mobile subscriber's current location correspondence.MSC/VLR is all sub-district issuing page messages in the lane place that LAI determines, carry this user's sign TMSI or IMSI in this message.The user is in this lane place, thereby can receive this beep-page message, and differentiates whether paging oneself by matching identification.
Each sub-district in this lane place has a plurality of paging channel usually, and each paging channel is divided into a plurality of subchannels again.In order to save battery of mobile phone, the specific user needn't monitor all channels, but monitors some subchannels of a certain paging channel.Each user utilizes pre-configured formula can determine paging channel and paging subchannel according to the paging channel and the number of subchannels of self IMSI and respective cell.Access Network also can be known paging channel and the subchannel that this user monitors according to same formula, so on the corresponding subchannel of this paging channel the phase issuing page message.
From the application of group system as can be seen, its stability of a system is extremely important.Even in case of emergency, when causing network line to interrupt, also should be able to provide certain communication service as reasons such as the attack of terrorism or natural calamities.But, sometimes in some cases, when taking place as natural calamities such as fire, flood or earthquakes, physical link between base station and the base station controller may disconnect, be to be under the ruuning situation of single station at this moment, do not have corresponding HLR and VLR and base station cooperating, thereby user in its coverage can't be followed the tracks of, certain IMSI that also can't know the user in the base station.When certain user of needs paging, can't provide corresponding IMSI or TMSI sign, Access Network also can't be determined corresponding paging channel and subchannel by IMSI, the base station can't provide the most basic service to the user in its overlay area, paging failure.
