2. when network size is big, because the roaming restricting data amount of sub-district roaming prescription formula is big, thereby cause configuration comparatively complicated, the system matches workload is also big.
3. for the travelling carriage that is in the cell boarder overlay region, owing to roam restriction by inserting the sub-district, logical phenomenon when breaking in the time of can occurring like this.
Another prior art is based on the roaming restricted version of PRL (first-selected roaming list) mode, this scheme basic thought is that CDMA WLL system is by wireless parameter management (Over the AirParameter Admini stration, OTAPA) function is controlled the PRL that stores in the terminal.The NID (network identity) of CDMA WLL system can be configured to cell level, and promptly each sub-district can corresponding unique N ID down for a BTS (base station).SID (system banner)/NID group among the terminal PRL is revised by the OTAPA process by CDMA WLL system, makes the SID/NID that stores in the terminal only identical with the corresponding SID/NID in certain sub-district.
After the user terminal start, at first carry out system and detect, search terminal is provided with the pilot signal of each sub-district in the frequency then, capture certain pilot signal on this frequency after, terminal just begins to accept the Sync Channel Message that this sub-district issues, and carries the SID/NID of BTS sub-district correspondence in this message; Terminal can with its PRL in SID/NID group corresponding district in search network, behind this network of terminal locking, just can be on this network by the access channel of eating dishes without rice or wine report location registers, begin to exhale, message such as page response carries out Business Processing.So just can guarantee to use in the SID/NID corresponding district that terminal registers when opening an account professional.
Yet above-mentioned prior art has following shortcoming:
1. to cell boarder overlay region user, because external cell is disturbed, can frequent appearance can't lock or lock mistake, speech quality can't guarantee.
2. this roaming restricted version all limits all business, comprises that urgent call, speech business, supplementary service, circuit type data service, Packet data service, short message etc. are all restricted.Urgent call is also limited, and is that urgent call can't be breathed out because terminal can't be used the restricted area access network.

Embodiment
Understand and realization the present invention the existing embodiments of the invention of describing in conjunction with the accompanying drawings for the ease of persons skilled in the art.
In order to realize the present invention, at first need on whole network, the roaming restriction of unified planning sub-district identify, each LAN is used same sub-district roaming restriction sign, and each LAN comprises at least one sub-district.The roaming restriction of described sub-district is designated SID/NID, LAC (lane place coding).Particularly, in whole network, the sub-district roaming restriction sign that each LAN is corresponding specific, the sub-district roaming restriction sign that different LAN is corresponding different.
As shown in Figure 1, the planning mode adopts following rule: with corresponding each LAN of the value of SID, the desirable arbitrary value of NID is 65535 as unified value.Wherein, the SID of all sub-districts of LAN 1 is 1, and NID is 65535; The SID of all sub-districts of LAN 2 is 2, and NID is 65535.Particularly, in whole network, different sid values is represented different LAN, and identical sid value is represented identical LAN, and each LAN comprises a plurality of sub-districts.
In Fig. 1, only adopted SID to represent LAN, should be noted that, also can adopt other method that whole network is planned.For example, can adopt the value of NID to represent LAN, that is to say, in whole network, the different different LAN of NID value representation, the identical identical LAN of NID value representation.Perhaps adopt the LAC value to represent LAN, that is to say, in whole network, the different different LAN of LAC value representation, the identical identical LAN of LAC value representation.
Secondly, travelling carriage is signatory roaming restriction when opening an account, and disposes its roams home restriction sign according to signatory roaming restriction, need identify its roams home restriction sign to all travelling carriages that belong to a LAN in the information of opening an account.To the contract purpose of roaming restriction of travelling carriage is can realize roaming in certain LAN in order to arrange it, after this travelling carriage having been disposed roams home restriction sign, show that this travelling carriage can limit realization roaming in the LAN that identifies in its this roams home, and can not in other LAN, realize roaming.As shown in Figure 1, all travelling carriages roams home restriction sign SID=1 in the information that opens an account in the LAN 1, the travelling carriage of its roams home restriction sign SID=1 can be realized roaming in LAN 1; All travelling carriages roams home restriction sign SID=2 in the information that opens an account in the LAN 2, the travelling carriage of its roams home restriction sign SID=2 can be realized roaming in LAN 2.
For convenience, hereinafter will be that example is represented sub-district roaming restriction sign with SID/NID.
Random limiting method of the present invention is described below.The basic thought of random limiting method of the present invention is: mobile station terminal reports each Active Set cell list and signal strength signal intensity when inserting or switch, network side takes out the SID/NID of each Active Set sub-district, judge that the SID whether sub-district is arranged in the Active Set cell list that reports equals the SID in the user configuration information, then allow call through if having, otherwise refusal inserts.Describe random limiting method of the present invention in the general voice calling procedure in detail below in conjunction with Fig. 2.
As shown in Figure 2, in step 201, travelling carriage sends initial call message to the base station, and described initial call message carries and activates cell list and this mobile station identification.
In step 202, the base station receives this initial call message, and sends the Connection Service request message according to this initial call message to Radio Access Controller, and described Connection Service request message carries and activates cell list and this mobile station identification.
In step 203, Radio Access Controller receives this Connection Service request message, and take out the activation cell list that carries in this message and this mobile station identification, from configuration, take out each sub-district corresponding district SID/NID according to cell list, obtain the ownership SID/NID of travelling carriage according to this mobile station identification.Then, sub-district SID/NID and user configured ownership SID/NID are mated,, then roam restriction, discharge this calling if all sub-district SID/NID are not equal to user configured ownership SID/NID; Otherwise, do not limit roaming, continue follow-up flow process.
Obtain the ownership SID/NID of travelling carriage according to this mobile station identification, several different methods can be arranged, for example, the contingency table of a mobile station identification and its ownership SID/NID can be in Radio Access Controller, established, its ownership SID/NID can be obtained by inquiring about this contingency table according to mobile station identification; Its ownership SID/NID also can directly be set in the attribute list of this travelling carriage, obtain its ownership SID/NID by inquiring about its attribute according to this mobile station identification.
In step 204, between Radio Access Controller and local switch, pass through the link establishment of V5 interface bearing.In step 205, Radio Access Controller sends assignment request message to the base station.In step 206, set up the air interface service channel between base station and the travelling carriage.In step 207, the base station is finished message with assignment and is sent to Radio Access Controller.In step 208, Radio Access Controller is dialed the travelling carriage of called number by the simulation of V5 chain road direction local switch.In step 209, local switch sends ring-back tone according to the situation of dialing the travelling carriage of called number to travelling carriage.If the called number travelling carriage is busy, then local switch sends busy ring-back tone to the caller travelling carriage.
According to the present invention, preferably, when planning sub-district roaming restriction sign, sub-district roaming restriction sign is associated with the area code of each single site network, as Guangzhou 020 correspondence 1/65535, Shenzhen 0755 correspondence 2/65535, at this moment, after base station system receives the initial call message of travelling carriage, can take out the sign and the Active Set sub-district of travelling carriage according to initial call message, find the respective user area code by mobile station identification, and then inquire about the roaming restriction sign that contingency table obtains user attaching, the roaming restriction sign of user attaching is roamed restriction sign with Active Set sub-district corresponding district compare by area code, if exist identical, then allow to call out, otherwise, roam restriction.Like this, mobile station identification and sub-district roaming restriction sign is mapped, base station system need not be carried out any configuration to user data just can realize local level roaming restriction.Following base station dilatation also need not to do any configuration modification.
Therefore, according to the present invention, after the whole network planning is finished, only need when opening an account, dispose travelling carriage the area code or the ownership SID/NID of local network, so configuration of the present invention is simple.
In addition, when travelling carriage is in the crossover region of two or more LAN, because the grand diversity that inserts with terminal when inserting and when switching is handled, and can effectively utilize the CDMA soft hand-off to improve overlay region speech quality like this, limiting user roaming scope at utmost again.
In addition, method of the present invention can not done the roaming restriction as fire alarm 119, robber and police 120 etc., thereby can farthest consider public interests special number.
According to the present invention, the speech quality for the crossover region that improves two local networks can interconnect by the A3/A7 interface between two local network RAC.
Though described the present invention by embodiment, those of ordinary skills know, without departing from the spirit and substance in the present invention, just can make the present invention that many distortion and variation are arranged, and scope of the present invention is limited to the appended claims.
