Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
In cdma system, portable terminal uses NID/system identification (NID/SID) to adjudicate whether roaming has taken place.A local network has distributed a pair of NID/system identification, stored the signatory NID/SID of portable terminal in the portable terminal, when it roams into other networks, NID/SID that portable terminal will receive by air interface and the NID/SID that himself preserves compare, if it is identical, then this system is the local CDMA network, otherwise this mobile terminal roaming has arrived other networks.
The present invention has utilized NID/SID, when networking, according to the roaming range of portable terminal NID/SID is set, and the BTS in the roaming range of mobile broadcasts this NID/SID; When portable terminal is contracted, the NID/SID of portable terminal place roaming range is stored in portable terminal; Portable terminal receives the NID/SID of BTS broadcasting, and the NID/SID with self storage is identical to judge the NID/SID that receives, if identical, access network then, otherwise portable terminal access network not.
Referring to Fig. 1, Fig. 1 is the cdma network structural representation of a preferred embodiment of the present invention.This net logically has been divided into a plurality of virtual MSC with a physics MSC when networking, for each virtual MSC is provided with a virtual MSC sign (V_MSCID).The scope of limiting mobile terminal roaming is in the local BTS in the present embodiment, so a BTS is provided with a NID/SID, the corresponding V_MSCID of NID/SID stores the corresponding relation of all NID/SID and V_MSCID among the HLR into; A V_MSCID is corresponding with all sub-districts (CELL) in the BTS; NID/SID of a BTS broadcasting.
Suppose that customer mobile terminal MS1 is defined in BTS1 (NID1/SID1) scope roaming, planning has 2 sub-district CELL1 below the BTS1, CELL2, CELL1 in MSC then, all corresponding V_MSCID1 of CELL2; It is NID1/SID1 that the HLR contracted user roams NID/SID, and V_MSCID1 corresponds to NID1/SID1.
When mobile terminal MS 1 is contracted NID1/SID1 is stored in portable terminal, and NID1/SID1 has been stored among the HLR as user profile.
If mobile terminal MS 1 is at BTS1, portable terminal receives the NID1/SID1 of BTS1 broadcasting, and judges that the NID1/SID1 that self stores when the NID1/SID1 that receives is signatory with it is identical, then can carry out location registers or calling.
Referring to Fig. 2, Fig. 2 is in cdma network structure shown in Figure 1, and mobile terminal MS 1 carries out the flow chart of location registers.This flow process may further comprise the steps:
Step 201, mobile terminal MS 1 sends position requests by BTS1 and BSC to MSC;
Step 202, MSC is that to obtain corresponding virtual MSC sign be V_MSCID1 to CELL1 according to the sub-district in the position requests;
Step 203, MSC reports HLR with V_MSCID1;
Step 204, HLR is NID1/SID1 according to the V_MSCID1 that reports finds the V_MSCID1 correspondence from stored relation NID/SID, NID1/SID1 in the user profile with itself and mobile terminal MS 1 when signatory compares, and this moment is identical, so continue location registers.
If mobile terminal MS 1 roams into BTS2, portable terminal receives the NID2/SID2 of BTS2 broadcasting, and judges that the NID1/SID1 that self stores when the NID2/SID2 that receives is signatory with it is inequality, and portable terminal can not access network.
The present invention can prevent that the user in order to realize roaming the NID/SID that revises self privately, has very high fail safe.For example, in the foregoing description, mobile terminal MS 1 be in order to roam into BTS2, and illegally the NID/SID with self storage has changed NID1/SID1 into, though can access network, can't carry out location registers.Still referring to Fig. 2, the process of its location registers may further comprise the steps:
Step 201, mobile terminal MS 1 sends position requests by BTS2 and BSC to MSC;
Step 202, MSC according to the sub-district in the position requests be CELL2 to obtain corresponding virtual MSC sign be V_MSCID2, V_MSCID2 is reported HLR;
Step 203, HLR is NID2/SID2 according to the V_MSCID2 that reports finds the V_MSCID2 correspondence from stored relation NID/SID, NID1/SID1 in the user profile with itself and mobile terminal MS 1 when signatory compares, and this moment is inequality, so the location registers failure.
In the present embodiment BTS is provided with a NID/SID, in actual applications, also can a NID/SID be set a CELL, the corresponding V_MSCID of NID/SID stores the corresponding relation of all NID/SID and V_MSCID among the HLR into; A V_MSCID is corresponding with a sub-district; A BTS broadcasts a plurality of NID/SID of its inner each sub-district correspondence.It is same as shown in Figure 2 that its portable terminal carries out the process of location registers.
By the above embodiments as seen, the method for limiting mobile terminal roaming can realize scope restriction exactly in this CDMA net of the present invention, and is safe.Internet resources and the interface-free resources having avoided causing owing to the frequent retry location registers of portable terminal are wasted, and network performance can be not influenced yet.Simultaneously, under the network optimization, dilatation, situation such as transfer, also need not to revise the MSC system data,, significantly reduced the system maintenance work amount as long as upgrade the CAMEL-Subscription-Information of portable terminal at HLR, can reach can commercialization standard.
