Description
Technical field
The invention belongs to moving communicating field, relate in particular to a kind of wireless local loop system, Radio Access Controller and method of handling urgent call.
Background technology
WLL system (Wireless Local Loop, wireless local loop) replaces the circuit between subsets and the exchange to connect with wireless connections, and the wireless access system of telecommunication service is provided.There is GSM (Global Systems for Mobile commutations in common WLL system, global system for mobile communications) WLL system, CDMA (Code Division Multiple Access, the code division multiple access access) WLL system and PHS (Personal Handy-phone System, personal wireless phone system) WLL system etc.
Emergence call service is meant that the user dials the business of urgent special service number, such as 110,110,119 etc., below is that example describes with 110.Owing to all be in special circumstances during user's emergency call, such as robber and police, fire alarm, first aid etc., require the system can be to user's call request this moment, accomplish the restriction of quick access, no authentication, do not have the restriction of opening an account, no arrearage restriction, insert and automatic transfer etc. nearby, for the restriction of quick access, no authentication, do not have the restriction of opening an account and do not have service such as arrearage restriction, prior art realizes.But for inserting nearby and switched service automatically, existing WLL system is done and imperfection needs to optimize and improve.
In the prior art, solve insert nearby and automatically a kind of scheme of switched service be among the RAC (Radio Access Controller, Radio Access Controller) in the WLL system, the professional frame of each RAC all to be reserved a part of telephone number.To dialing all urgent calls of special service number, the number resource that directly uses this business frame to reserve inserts LE (Local Exchanger, local switch).For the user of RAC internetwork roaming, the LE of the professional frame connection of the RAC on access roaming ground nearby.To the disabled user or the user that do not open an account, also can use the reserved number resource, placement of emergency calls is done the call source analysis according to caller information on LE, route calls to the special service number of appointment.
In this scheme, at first, the reserved number resource is distributed unitedly in the professional frame of the RAC of WLL system, the caller information of access code may have identical call source attribute, because going up, LE realizes that the function of switching special service number is to analyze according to the call source attribute of caller information automatically, if all reserved number call source attributes of a professional frame are all identical, all users in then should the business frame, can only corresponding unified special service number, LE carries out route analysis according to the information of reserved number, 110 alarm centers of appointment can be inserted automatically, but the at county level other 110 warning working telephones of segmentation can not be transferred to automatically.
Secondly, if a WLL system has covered a plurality of local networks, a professional frame as RAC has connected a plurality of LE, each LE is to there being an area code, because the affiliated geographic area of all LE that this professional frame connects all is under the jurisdiction of a unified spy and obeys the center, so can't be transferred to each prefecture-level city oneself independently special clothes center automatically by LE.
Therefore, this scheme is only applicable to a professional frame and only connects a local network, the situation of having only unified EC in local network, can not solve in single professional frame Duo Xian, the many prefecture-level cities of single professional frame is to require the problem of the special clothes of switching target working telephone automatically under the Multiple Area Code Function situation.
Another solution is for urgent call, and the WLL system does not do special processing, uses user's caller information to insert LE as normal call, does the call source analysis on LE, is routed to the special service number of appointment.When professional frame of the RAC of WLL system meets a plurality of other LE at county level, can realize transfer the automatically working telephone of appointment of special service number, dial that system can be transferred to the working telephone of each public security bureau at county level correspondence automatically at 110 o'clock as the user.Simultaneously, when the RAC of WLL system supports Multiple Area Code Function, can realize transfer the automatically working telephone of appointment of special service number.
But in this scheme, can not urgently call on urgently for disabled user and the user that do not open an account and to cry, limit the scope of urgent call.Simultaneously, when the roamer dials, because the user uses is caller information when opening an account, the WLL system can be linked into calling on the ownership LE when opening an account, when ownership LE carries out route analysis to special service number, still urgent call be linked into the roamer the ownership county, the ownership city the spy obey the center, can not realize the function that inserts nearby.
In sum, in the prior art, because the WLL system can cover very big scope, such as striding a plurality of local networks, perhaps in a local network, covered a plurality of counties, and each local network, perhaps each county, the administration of oneself is all arranged, the own corresponding special mechanism of obeying can be set, such as one 110 working telephone in a county.For the intrasystem user of WLL, if roaming transcounty, that stride prefecture-level city taken place, then always insert the end office switch of opening an account originally during emergency call, can not obtain relief nearby.For the disabled user, when not opening an account user's emergency call, perhaps the WLL system can't insert, though perhaps use number that WLL reserves access switch nearby, but because a WLL coverage is very big, the frame of a RAC may connect a plurality of end office switch, can not determine insert which end office switch according to the current present position of WLL user, nearest spy obeys working telephone thereby switch also just cannot be transferred automatically.
