Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples, and with reference to accompanying drawing, the present invention is described in more detail.
Core content of the present invention is: by dispose the corresponding relation of roamer and PACA grade in advance on MSC/VLR, making MSC/VLR can be that the user who roams into self coverage distributes the PACA grade according to the corresponding relation of pre-configured roamer and PACA grade, and when MSC/VLR need be for this roamer's replay call, according to the PACA grade of distributing is this roaming user preferential assignment wireless channel, makes this roamer can preferential access wireless channel.
As shown in Figure 1, Fig. 1 realizes the method flow diagram of roaming user preferential access wireless channel overall technological scheme for the present invention, the corresponding relation of configuration roamer and PACA grade on MSC/VLR in advance, and this method may further comprise the steps at least:
Step 101:MSC/VLR judges whether the interior user of self coverage is the roamer, if then execution in step 102; Otherwise, process ends;
Step 102:MSC/VLR distributes the PACA grade according to the corresponding relation of described roamer and PACA grade for this roamer;
Step 103:MSC/VLR during for this roamer's replay call, judges whether there is available wireless channel in the Radio Resource, if then execution in step 104 at needs; Otherwise, execution in step 105;
Step 104:MSC/VLR is wireless channel of this roamer's assignment in available wireless channel, and this roamer inserts the wireless channel of MSC/VLR assignment;
Step 105:MSC/VLR is according to the PACA grade of distributing for this roamer, remove the local exchange user's lower speech channel than this roamer PACA grade, discharge the shared wireless channel of this speech channel, and giving this roamer with the wireless channel assignment that discharges, this roamer inserts the wireless channel of MSC/VLR assignment.
For the above-mentioned corresponding relation of configuration roamer and PACA grade on MSC/VLR in advance, when this corresponding relation of concrete configuration, can on MSC/VLR, dispose all corresponding identical PACA grade of all types of roamers, also can on MSC/VLR, dispose the corresponding different respectively PACA grade of dissimilar roamers.In addition, the corresponding relation of roamer who disposes on MSC/VLR and PACA grade also can be made amendment according to actual needs.
If all corresponding identical PACA grade of all types of roamers of configuration then can be distinguished roamer and local user on MSC/VLR.At this moment, in the time of in a certain user roams into the scope that MSC/VLR covers, MSC/VLR will be PACA ranking score dispensing this roamer corresponding with all types roamer of configuration.
If the dissimilar corresponding different respectively PACA grade of roamer of configuration on MSC/VLR, for example dispose the international roaming user PACA grade corresponding different respectively with national roaming subscriber, then not only roamer and local user can be distinguished, but also international roaming user and national roaming subscriber among the roamer can be further distinguished.At this moment, in the time of in a certain user roams into the scope that MSC/VLR covers, MSC/VLR will configuration with this roamer of the corresponding PACA ranking score of the type roamer dispensing.
Generally speaking, because international roaming user's communications rate is than the communication rate height of national roaming subscriber, can dispose higher PACA grade to the international roaming user, to the lower PACA grade of national roaming subscriber configuration, make the international roaming user can be better than the national roaming subscriber access wireless channel, national roaming subscriber can be better than local user's access wireless channel.
Certainly, in some cases, also can dispose higher PACA grade, to the lower PACA grade of international roaming user configuration to national roaming subscriber, make national roaming subscriber can be better than international roaming user access wireless channel, the international roaming user can be better than local user's access wireless channel.
Judging for the MSC/VLR described in the step 101 whether the user in self coverage is the roamer, is that MSC/VLR is according to carrying out with the corresponding international mobile subscriber identifier of Subscriber Number (IMSI) prefix.
IMSI is used for number that the mobile subscriber distributed of unique identification in the world, includes ten five digit number.Generally speaking, the IMSI prefix is preceding ten one-bit digitals in the IMSI character string.The front three numeral is used to represent different countries in the IMSI prefix, and the 4th is used for the operator that represents that same country is different to five digit number, and the 8th to ten one-bit digital is used for city or the area of representing that same country is different.
Because the area of each MSC service is fixed, each MSC also fixes for the IMSI prefix that the interior user of self coverage distributes, and each regional IMSI prefix is different.So MSC/VLR can determine that the user is local user or roamer according to user's IMSI prefix, if the roamer can also determine that further the user is international roaming user or national roaming subscriber.
When specific implementation, MSC/VLR can judge that the structure of this table is as follows by the user type table of inquiring about self:
| MSCID | The IMSI prefix | User type |
| X | 46003091234 | National roaming subscriber |
| … … | … … | … … |
In last table, mobile switching centre's sign (MSCID) is made of SYSTEM ID and SWITCH NO., is used for MSC of unique identification.The MSCID that in above-mentioned user type table, needs MSCID is configured to this MSC.User type has local user, national roaming subscriber and international roaming user.
MSC/VLR passes through just can determine this user's type to the above-mentioned user type table of user inquiring in self coverage.Generally speaking, the roamer roams into a place, needs to register to local MSC/VLR, and MSC/VLR just can determine this user's type to the above-mentioned user type table of user inquiring of registration.
Distribute the PACA grade for the corresponding relation described in the step 102 for this roamer according to described roamer and PACA grade, if all corresponding identical PACA grade of configuration all types roamer on MSC/VLR is then with this PACA ranking score dispensing roamer.If the corresponding different respectively PACA grade of the dissimilar roamers of configuration on MSC/VLR, then will with the roamer of the corresponding PACA ranking score of the type roamer dispensing the type.
For example, the corresponding higher PACA grade of configuration international roaming user on MSC/VLR, the lower PACA grade of configuration national roaming subscriber correspondence, judge that at MSC/VLR this user, can be with higher PACA ranking score dispensing this international roaming user corresponding with the international roaming user for after the international roaming user; Judge that at MSC/VLR this user, can be with lower PACA ranking score dispensing this national roaming subscriber corresponding with national roaming subscriber for after the national roaming subscriber.
In addition, the PACA business if the roamer has contracted simultaneously, then MSC/VLR distributes the PACA grade according to the roamer of configuration and the corresponding relation of PACA grade for this roamer, does not conflict for this user distributes the PACA grade according to the PACA business that the user contracts with MSC/VLR.At this moment, MSC/VLR can be set distribute the PACA grade for this roamer, MSC/VLR also can be set choose high a kind of of PACA grade in above-mentioned two kinds of foundations and distribute the PACA grade for this user according to the roamer of configuration and the corresponding relation of PACA grade.
Specifically, if being set, MSC/VLR distributes the PACA grade for this roamer according to the roamer of configuration and the corresponding relation of PACA grade, after the user of the PACA business of having contracted roams into the scope of MSC/VLR covering, MSC/VLR judges whether this user is the roamer, if then distribute the PACA grade for this roamer according to the roamer of configuration and the corresponding relation of PACA grade; Otherwise, do not distribute the PACA grade for this roamer.
If MSC/VLR is set to be chosen high a kind of of PACA grade in above-mentioned two kinds of foundations and distributes the PACA grade for this user, after the user of the PACA business of having contracted roams into the scope of MSC/VLR covering, MSC/VLR is according to roamer and the corresponding relation of PACA grade and the PACA business that this user contracts of configuration, be respectively this roamer and distribute a PACA grade, the height that compares these two PACA grades then selects higher PACA grade as the PACA grade of distributing to this roamer.
