Description
Technical field
The present invention relates to wireless local telephone system, in a kind of wireless local telephone system to the processing method of beep-page message.
Background technology
GSM (Universal Mobile Telecommunications System) is used widely all over the world, and the base station of the Cellular Networks in the gsm system generally has large-scale and expensive structure, and height can reach tens meters, and the service area radius can reach tens kilometers; Traditional Cellular Networks communication speech quality generally very low (8 kilobits/second to 13 kilobits/second); Traditional Cellular Networks communication also is subjected to the traffic quantitative limitation that can carry, and when the user increased, it is crowded that system becomes.A kind of new wireless communication standard was rapidly developed in recent years, promptly frequency range is carried out the microcellulor standard of radio communication near 1990MHz, comprising: the PACS of the U.S. (individual incoming communication system), the DECT (digital enhanced cordless telecommunications system) in Europe, the PHS (personal hand held phone system) of Japan etc.
Personal hand held phone system (PHS) development of Japan is ripe, and obtains large-scale application on Japan and China and other places.PHS has following advantage compared with gsm system: the base station is little and cheap, installs very conveniently, and transmitting power is little; Its narrow band transmission form forms in the 10MHz subband than multifrequency point, and user capacity is compared greatly; Better, the various data service bandwidth of speech quality (32 kilobits/second) higher (64 kilobits/second).But shortcoming is arranged also: can only support the user that moves than low velocity; Because service area is little, switches more frequent.In view of the as above characteristics of PHS system, it becomes China's mainstream technology of development low speed, the wireless local telephone system that moves among a small circle at present.The Personal Handyphone System(PHS) total number of users of China nearly 1,000 ten thousand, and will continue growth.
The PHS system is because base station power is little, covering effective radius generally is 500-1500m, and therefore for covering same city, the PHS system has the base station of a lot of quantity, for example for the medium-sized city at one 200 general-purpose family, its base station number generally will reach about 5000.
The common networking structure of PHS system is made of PHS system gateway, access unit, base station controller, base station, terminal and paging lane place.As shown in Figure 1, the PHS system gateway is finished signaling exchange and the control of the intrasystem system of PHS with PSN, the switching of the BTS management cross base station controller of access unit processing wireless access side and Signalling exchange etc., base station controller is mainly finished the signaling of base station and is safeguarded and handle that the demodulation function of aerial signaling is mainly finished in the base station.The paging lane place is a logical concept, is not physical entity, is the logic flag in certain zone, and it is an important symbol in the user property, and a common paging lane place comprises one or more base station controller.In existing P HS system, system sends paging information according to paging lane place all base station controllers in the paging lane place during calling called subscriber.When the user moved to different pagings lane place, terminal can be initiated location updating message, and system preserves the up-to-date paging location area information of user.
The physical connection of base station controller and base station adopts ISDN u interface line, its physical transfer generally can not surpass 3Km, therefore the region of base station controller covering is limited, its with base station number all fewer, like this, a paging lane place will certainly comprise a plurality of base station controllers, and not in GSM a paging lane place only comprise a base station controller.In mobile radio system, because being broadcast, handles called paging, each base station controller in the paging lane place will be handled the beep-page message of whole paging lane place, the processing load that this meeting brings a large amount of message congestions to base station controller and increased base station controller, reduced the treatment effeciency of base station controller, particularly can influence the call completion ratio of whole system at heavy traffic period.
Usually why the PHS system needs to all base station controller pagings, be because system and do not know the base station controller information at the current place of user, if the energy recording user is base station controller message accurately, just can avoid this problem, attaching position register HLR is all customer position informations of storage system, a kind of solution that is similar to gsm system is after user place base station controller changes, send the base station controller updating message by the PHS system gateway to attaching position register HLR, but because the base stations control district is less relatively in the PHS system, its change message is more, if adopt this scheme, communication meeting between PHS system gateway and the attaching position register is very frequent, will produce the another one communication performance bottleneck, can bring instability to system equally.
Summary of the invention
Purpose of the present invention solves in the existing wireless local telephone system excessive because of the excessive system loading that makes of beep-page message flow exactly, thereby influence the problem of system's call completion ratio, propose to reduce in a kind of wireless local telephone system the method for beep-page message flow, can alleviate the load of each base station controller, reduce message congestion, improve the called paging call completing rate.
Reduce the method for beep-page message flow in a kind of wireless local telephone system, comprise the following steps:
(1) the base station controller information that an embedded dynamic data base is preserved the user is set in the Access Network unit;
(2) lead the user exhale, the position dynamically updates database information when upgrading;
(3) the Access Network unit is received behind the system gateway call signaling and to be obtained this user's base station controller information to data base querying;
(4) beep-page message is initiated to this base station controller in the Access Network unit;
(5) whether the Access Network unit judges receives called subscriber answer, if receive then continue to finish the call proceeding flow process of back;
(6) if the Access Network unit is not received is replied, then all base station controllers in this paging lane place are initiated beep-page message, receive the call proceeding flow process of finishing the back after replying.
Described step (4) comprises the legitimacy of checking the user before this base station controller is initiated beep-page message earlier, if the legal beep-page message of just initiating of user.
After base station controller was received beep-page message, called paging message was sent in all base stations under its management, sends to the called subscriber by the base station again.
In existing wireless local telephone system, adopt method of the present invention, only need that software is carried out less change and just can reduce the called paging message traffic effectively, the corresponding disposal ability that strengthens base station controller, improved the percept of call completed of system, bearing high traffic for local telephone system has very obvious than effect under the big meaning, particularly high traffic situation.
