The terminal use sends to the BTS at its place and calls out, and after this BTS receives this calling, will send to the RAC that is connected with this BTS in this calling.
The customer data base of step 202:RAC inquiry WLL network, whether inquire about this user is the user of WLL network, if, execution in step 203, otherwise, execution in step 204.
RAC receives after the calling, and respective handling is carried out in the calling that it can be defaulted as the user of WLL network:
RAC resolves the calling that is received, obtain the user of this calling user ID (such as: IMSI), RAC can be according to the customer data base of the local or long-range WLL network of user ID inquiry then, determine whether the user is WLL user: if there is this user in the customer data base of WLL network, then can judge the user of this user, execution in step 203 for the WLL network.
If there is not this user record in the customer data base of WLL network, show that this user is not the user of WLL network, then can infer the user of this user, execution in step 204 for the mobile network.
Step 203:RAC submits to calling the LE of WLL network by the V5 interface.
After the LE of WLL network receives calling, can this calling be handled accordingly according to present WLL call treatment technique.
Step 204:RAC submits to calling mobile network's MSC by the A interface.
If in step 202, there is not this user record in the customer data base of WLL network, show that this user is not the user of WLL network, then can infer the user of this user for the mobile network, then carry out this step.
RAC will call out second network that corresponding user inserts as this RAC: mobile network's user, will call out by the A interface, and submit to mobile network's MSC.
After mobile network's MSC receives calling, can this calling be handled accordingly according to the treatment technology of this present mobile network to calling out.
After RAC submits to mobile network's MSC with calling, if RAC receives the information to this call treatment failure that mobile network's MSC returns, and the reason that is resolved to this processing failure is: this user is not this mobile network's user, i.e. this user's the information of opening an account not in mobile network's customer data base, then RAC can judge this user neither the user of the WLL network that this RAC inserts, be not another network that it inserted: mobile network's user yet, then RAC can handle current calling as defective ringing: return the access error message to the terminal use, perhaps any processing is not carried out in this calling.
Certainly,, do not receive the processing failure information that this mobile network's MSC returns, show that then MSC successfully carries out respective handling to business if RAC submits to calling after mobile network's the MSC.
Therefore, owing to use the present embodiment method, RAC is after receiving any calling, RAC handles all-calls according to WLL user, the customer data base of inquiry WLL network, judge whether this user is the user of WLL network, if the LE that then this calling is forwarded to the WLL network handles; Only when RAC confirmed that the user of current calling correspondence is not the user of WLL network, RAC transferred to this calling second network with its access again: the mobile network, handled by this mobile network.As seen, use the present embodiment method, realized using the access of same RAC WLL network, mobile network.Promptly realized the application of the same wireless access part of WLL network and mobile network sharing.

After mobile network's MSC receives calling, can this calling be handled accordingly according to the treatment technology of present mobile network to calling out.
Step 303: if RAC receives the processing failure information that this mobile network returns, and this information shows that this user is not this mobile network's user, and then execution in step 304; Otherwise, the method ends flow process, RAC disposes to this calling.
RAC will call out the user that corresponding user is defaulted as the mobile network, and after this calling being submitted to mobile network's MSC, if this RAC receives the processing failure information that this MSC returns, and being resolved to the reason of handling failure is: this user is not this mobile network's user, i.e. this user's the information of opening an account not in mobile network's customer data base, then the RAC execution in step 304.
The customer data base of step 304:RAC inquiry WLL network, whether inquire about this user is the user of WLL network, if, execution in step 305; Otherwise, execution in step 306.
RAC can resolve the calling that is received, obtain the user of this calling user ID (such as: IMSI), then, RAC can determine whether the user is WLL user according to the customer data base of user ID at the local or long-range WLL network of inquiry.If there is this user in the customer data base of WLL network, then can judge the user of this user, execution in step 305 for the WLL network; If there is not this user record in the customer data base of WLL network, then RAC can infer the user that this usefulness is not two networks (mobile network and WLL network) that inserted per family, execution in step 306.
Step 305:RAC should call out by the V5 interface, submitted to the LE of WLL network.
If there is this user in the customer data base of WLL network, then can judge the user of this user for the WLL network, then carry out this step: will call out by the V5 interface, and adopt the V5 interface protocol, and submit to the LE of WLL network.

Embodiment 3:
Fig. 4 is the schematic flow sheet of the call route method of present embodiment, and as shown, this method comprises:
Step 401:RAC receives the calling that BTS reports.
The terminal use sends to the BTS at its place and calls out, and after this BTS receives this calling, will send to the RAC that is connected with this BTS in this calling.
Step 402:RAC resolves to call out and obtains user property.
RAC resolves this calling after receiving customer call.If carry attribute of user information in this calling, then can directly obtain attribute of user information and can know that then this user is the user of WLL network according to analysis result, or mobile network's user; If carry this user's user ID in this calling, such as: international mobile subscriber identity (International Mobile Subscriber Identity, be called for short IMSI), then can be according to this user ID, the attribute of user relation table of inquiry Local or Remote storage is determined this attribute of user, and then know that this user is the user of WLL network, or mobile network's user.
Can adopt following dual mode in this attribute of user relation table:
First kind of mode: the pairing attribute of each user ID in the network is registered.Specifically as shown in Table 1:
Table one
User ID Attribute of user
User ID 1 Attribute of user 1
User ID 2 Attribute of user 2
The second way: the user to WLL network in the network and mobile network carries out unified planning, equitable subsection, then on each RAC or an other database, the relation on attributes table of unified configure user, make number section at each user ID place, corresponding with attribute of user respectively.With the user ID is that IMSI is an example, and this attribute of user relation table can adopt the form shown in the table two.
Table two
The literary name section Literary name section implication
Initial IMSI IMSI section initial value
Finish IMSI IMSI section end value
Attribute of user This number section attribute of user, attribute of user can be the user of WLL network or mobile network's user
Because the division of form basis section shown in the table two, the form shown in its phase his-and-hers watches one has unified planning to the user, uses the capacity of attribute of user table of this form less relatively, safeguards comparatively simple.
If, this attribute of user relation table adopts the form shown in the table two, then RAC can be according to the IMSI that is resolved to, the relation on attributes table of inquiring user, mate the affiliated IMSI section of this IMSI, then can know the attribute of user of this number section correspondence, thereby learn that this user still is mobile network's user for the user of WLL network.
Step 403:, this calling is submitted to corresponding network according to attribute of user.
RAC directly obtains attribute of user according to the Query Result of step 402: current user perhaps is mobile network's user for the user of WLL network.
If the Query Result of step 402 shows: this attribute of user is the user of WLL network, after then the LE of WLL network receives calling, can this calling be handled accordingly according to present WLL call treatment technique.
If the Query Result of step 402 shows: this attribute of user is mobile network's user, then RAC submits to mobile switching centre's (Mobile services Switching Center is called for short MSC) by the A interface with calling.MSC uses the corresponding mobile procotol, and calling is handled.Here be that cdma network is an example with this mobile network, use the A interface protocol of cdma network correspondence, this calling is submitted to the MSC of cdma network.After the MSC of cdma network receives calling, can this calling be handled accordingly according to present CDMA call treatment technique.
If in step 402, can't inquire this attribute of user information, be that RAC knows that this usefulness is not the WLL network of this RAC access and mobile network's user per family, then RAC can handle current calling as defective ringing: return the access error message to the terminal use, perhaps any processing is not carried out in this calling.
Therefore, because RAC can be the user of WLL network or mobile network's user according to the user of the calling that is received, and correspondingly carry out different calling routes and handle, route the call to corresponding WLL network or mobile network.Realized using the access of same RAC to WLL network, mobile network.Promptly realized the application of the same wireless access part of WLL network and mobile network sharing.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is to instruct relevant hardware to finish by program, described program can be stored in the computer read/write memory medium, this program is when carrying out, can comprise the steps: the Radio Access Controller receipt of call, and determine the attribute of user of this calling; If this attribute of user is: the user of first network that this Radio Access Controller inserts, then Radio Access Controller is submitted to described first network with this calling; If this attribute of user is: the user of second network that this Radio Access Controller inserts, then Radio Access Controller is submitted to second network with this calling.Here the alleged storage medium that gets, as: ROM/RAM, magnetic disc, CD etc.
