Abstract

The embodiments of the present invention disclose a method for issuing paging messages and an MSC/VLR, the method includes: determining types of networks terminating the process. if the MS only accesses a 2G network; issuing, by the MSC/VLR, paging messages on an RNC, and terminating the process, if the MS only accesses a 3G network; and issuing, by the MSC/VLR, paging messages on both the BSC and RNC, if the MS accesses both the 2G network and the 3G network. According to the embodiments of the present invention, the MSC/VLR can choose to issue paging messages on the BSC or the RNC separately or on both the BSC and the RNC, since it can determine the types of networks accessed by the MS. Thus, unnecessary paging messages issued on the BSC same time, a great deal of radio paging channel resources on the BSC or the RNC is saved, which greatly reduces effects on the process of paging other MSs.

Claims

1. A method for issuing paging messages, comprising:

determining types of networks accessed by a Mobile Station (MS);

issuing, by a Mobile Switching Centre/Visited Location Register (MSC/VLR), paging messages on a Base Station Controller (BSC) and terminating the process, if the MS only accesses a Second Generation Mobile Communication System network (2G network);

issuing, by the MSC/VLR, paging messages on a Radio Network Controller (RNC), and terminating the process, if the MS only accesses a Third Generation Mobile Communication System network (3G network); and

issuing, by the MSC/VLR, paging messages on both the BSC and RNC, if the MS accesses both the 2G network and the 3G network.

2. The method of claim 1, wherein the determining types of networks accessed by the MS comprises:

determining, by the MSC/VLR, the types of networks accessed by the MS according to an International Mobile Subscriber Identifier/Mobile Station International Integrated Service Digital Network Number (IMSI/MSISDN) and an MS access network type list stored in the VLR.

3. The method of claim 2, wherein the MS access network type list comprises a corresponding relationship between a number section of IMSI/MSISDN and the types of networks accessed by the MS.

4. The method of claim 1, wherein the determining types of networks accessed by the MS comprises:

determining, by the MSC/VLR, the types of networks accessed by the MS according to Access Restriction Data (ARD) information stored in the VLR.

5. The method of claim 4, wherein the ARD information is inserted into the VLR by a Home Location Register (HLR) through an insert Subscriber Data message during a process of location registration.

6. The method of claim 4, wherein the ARD information is subscribed while the MS opens an account, and is used for indicating the types of networks accessed by the MS.

7. The method of claim 1, wherein the determining types of networks accessed by the MS comprises:

inquiring, by the MSC/VLR, about version information submitted by the MS; and

determining that the MS accesses the 2G network, if the version of the MS is the one before R99;

inquiring, by the MSC/VLR, about an access capability of the MS in a data structure for storing attributes of the MS in the VLR according to the IMSI/MSISDN of the MS, if the version of the MS is the R99 or the one after R99; and

determining that the MS only accesses the 2G network if the MS is only capable of accessing the 2G network;

determining that the MS only accesses the 3G network if the MS is only capable of accessing the 3G network; and

determining that the MS accesses both the 2G and 3G networks if the MS is capable of accessing both the 2G and 3G networks.

8. The method of claim 7, wherein the version information is contained in a Revision level parameter of classmark1 information submitted to the MSC/VLR by the MS.

9. The method of claim 7, wherein the data structure for storing the attributes of MS in the VLR at least comprises one of the following:

IMSI number, the MSISDN, subscription information and the access capability.

10. The method of claim 1, wherein the determining types of networks accessed by the MS comprises:

determining, by the MSC/VLR, the types of networks accessed by the MS, according to at least two of;

IMSI/MSISDN of the MS and an MS access network type list stored in the VLR, ARD information stored in the VLR, and the version information submitted by the MS and an access capability of the MS.

11. A Mobile Switching Centre/Visited Location Register (MSC/VLR), comprising:

a first unit, for determining types of networks accessed by a Mobile Station (MS);

a second unit, for issuing paging messages on a Base Station Controller (BSC), and terminating the process, if the MS only accesses a Second Generation Mobile Communication System network (2G network);

issuing paging messages on a Radio Network Controller (RNC), and terminating the process, if the MS only accesses a Third Generation Mobile Communication System network (3G network); and

issuing paging messages on both the BSC and RNC if the MS accesses both the 2G network and the 3G network.

12. The MSC/VLR of claim 11, wherein the first unit is configured for determining the types of networks accessed by the MS according to an International Mobile Subscriber Identifier/Mobile Station International Integrated Service Digital Network Number (IMSI/MSISDN) and an MS access network type list stored in the VLR.

13. The MSC/VLR of claim 11, wherein the first unit is configured for determining the types of networks accessed by the MS according to Access Restriction Data (ARD) information stored in the VLR.

14. The MSC/VLR of claim 11, wherein the first unit is configured for inquiring about version information submitted by the MS, and determining the types of networks accessed by the MS according to the version information.

15. The MSC/VLR of claim 11, wherein the first unit is configured for determining the types of networks accessed by the MS, according to at least two of:

IMSI/MSISDN of the MS and an MS access network type list stored in the VLR, ARD information stored in the VLR, and the version information submitted by the MS and an access capability of the MS.
