HLR 15 to process mobile communication subscriber calls. The MSC 14 interfaces with theBSC 13 to perform call setup and release and various functions such as call processing and supplementary service related functions. - Here, the VLR is a database for temporally storing subscriber information related the
MS 11 within the service area of the VLR. The VLR downloads information of theMS 11 and the subscriber registered within its serving area from theHLR 15 to store temporally, which is located within the MSC 14. - The
HLR 15 that is a circuit management server is a database, connected to the MSC 14, for managing information of the mobile subscribers. The HLR 15 interacts a number of theMSCs 14 to perform subscriber location registration and stores permanent information of theMS 11 and the subscriber and location information. TheHLR 15 interacts with the VLR to support the call processing and various functions related to the supplementary services. In particular, in a circuit network, the HLR 15 provides voice call related mobility and service related function. - Also, the AUC that is a circuit management server performs authentication procedure by using unique algorithm with the
Ms 11 to check whether theMS 11 is permitted to access the circuit network when theMS 11 requests a call to the network. - The
AAA server 16 performs authentication for access from thePDSN 17 to thePDSN 17 when the MS requests data service and management function for encryption key and encryption level for data encryption and accounting data collection function when theMS 17 transfers data in the Internet. - As shown in
FIG. 1 , since the circuit network for voice and the packet network for data are discriminated in the convention next generation mobile communication system, they have respectively the subscriber servers, theAAA server 16 and the HLR(AUC) 15. - As described above, mobility and authentication functions are performed by separate procedures in the separate networks in the convention next generation mobile communication system. Since the ALL-IP network integrates all the networks, call processing procedure is very complex if mobility and authentication functions are respectively performed by the
conventional HLR 15 and the AUC. Furthermore, when voice is transferred through the Internet in an IP packet, it is believed to be impossible to encrypt properly in the Internet, and security problems may be induced. Therefore, mobility and authentication functions should be integrated to be proper to the Internet in the ALL-IP network, for which it is required to have a common subscriber server. The prior art is not believed to meet these objectives. - Therefore, it is an object of the present invention to provide a common subscriber managing apparatus for commonly managing functions such as mobility management function, call related service management function, QoS (Quality of Service) management function, authentication and authorization management function, accounting management function and other existing subscriber server function by using common subscriber database in an ALL-IP (internet protocol) network that is based on a next generation mobile communication network, a method therefore, and a computer readable recording medium for recording a program for implementing the method.

Therefore, the present invention provides a CSS (Common Subscriber Server) for use in the ALL-IP network. That is, the present invention provides a functional model of the CSS, which uses commonly mobility management function, call related service management function, QoS (Quality of Service) management function, authentication and authorization management function and accounting function by a common subscriber database.
- While conventional authentication procedure for voice is performed during network access, encryption translation procedure is required at a final node of a packet network after Bearer data encryption after SA (Security Association) is performed in the conventional Internet in the ALL-IP in which voice is transferred in IP frames.
- In order to introduce such an Internet related authentication technique, SA setup and authentication key management function that are performed at the AAA server of the conventional packet network should be introduced. For effective call scenario, the CSS should include mobility management function and service management function. Therefore, the CSS performs commonly the mobility management function, the QoS management function, the service management function, the authentication and authorization function and the accounting function.
- By using the CSS capable of supporting an Internet authentication mechanism required in the ALL-IP network, the present invention is capable of message encryption/decryption of the IP scheme when voice is transferred in the IP frames so as to perform complete security processing for voice and provide the mobility management function, the QoS management function, the service management function, the authentication and authorization function and the accounting function.
- Hereinafter, several embodiments of the present invention and measurement results will be described in detail with reference to the accompanying drawings.
-
FIG. 2 shows a diagram of one embodiment of a CSS in an ALL-IP network in accordance with the present invention. - As shown in
FIG. 2 , the CSS in the ALL-IP network of the present invention comprises a MS (Mobile Station) 21 that is compatible to a media (voice, image, moving image data) standard that is supported by the ALL-IP network, a RAN (Radio Access Network) 22 for controlling wireless resource of theMS 21 and wireless traffic, controlling handoff, realigning data from/to apacket network 25 based on a request of theMS 21 to have interface criteria, and providing the realigned data to theMS 21, a CCF (Call Control Function) 23 for controlling a call between theRAN 22 and aCSS 24, and theCSS 24 for providing SA setup function for voice processing and commonly managing the mobility management function, the QoS management function, the service management function, the authentication and authorization function and the accounting function for theMS 21 by using a common subscriber database. - Comparing with the conventional next generation mobile communication system as shown in
FIG. 1 , the ALL-IP network comprises theCCF 23 for call control function instead of a MSC (mobile switching center) and theRAN 22 includes an IP BSC (Base Station Controller) 222, an IP BTS (Base Station Transceiver) 221 as shown inFIG. 2 . - Here, the
IP BSC 222 can be omitted but theIP BSC 221 is itself connected to the IP network, i.e., theIP BSC 221 is an IP node. - Therefore, the
RAN 22 can be constructed in many forms including theIP BTS 221, theIP BSC 222 and the IP FCF (Packet Control Function) 223. - The
RAN 22 controls wireless resources management and wireless traffic and controls handoff. Also, theRAN 22 combines input signals through multi-path or selects one of frames during the handoff to improve the QoS. - When the
IP BTS 221 is the IP node, functions of theconvention IP BSC 222 are distributed to theIP BTS 221 andCCF 23 of the core network so that the IP BSC can be omitted. For this, some problems should be solved. - Firstly, during soft handoff between the
IP BTSs 221, quality of data that is transferred from theMS 21 to the network is improved by diversity function. That is, data transferred via the multi-path are combined or one of frame is selected to improve the quality of data. - Since frame selection function is disposed at the
conventional IP BSC 222, it should be submitted to one of theIP BTS 221 and the core network. However, because the core network can not take this frame selection function, this function is disposed at theIP BTS 221. At this time, because the frame selection could induce frequent data generation between theIP BTSs 221, a solution, i.e., location of a proper diversity apparatus, is requested. - Secondly, another point that should be considered in location of the frame selection apparatus is that the QoS is not certain in the Internet. Therefore, a connecting method between an apparatus that is implemented for the frame selection function that requires real time processing and the
IP BTS 221 should be provided. - For this, the frame selection apparatus is discriminated as a diversity apparatus separate from the
IP BTS 221, which is connected to theIP BTS 221 through a direct path instead of the conventional Internet path. Here, because the Internet cannot satisfy real time characteristic as described above, the frame selection is performed effectively using the direct path. Of course, when the Internet can certain real time processing enough, the direct path can be replaced with the Internet obviously. In particular, the location of the diversity apparatus can be performed using a number of methods. Desirably, eachIP BTS 221 has the diversity apparatus and a direct path provides between the diversity apparatuses in the ALL-IP network, or each group ofIP BTS 221 has the diversity apparatus and a direct path provides between the diversity apparatuses and between theIP BTS 221 and the diversity apparatus so that the frame selection function can be supported during the soft handoff. The selection criteria can be capability of the diversity apparatus. - The
RAN 22 that can be implemented in various forms transfers data between theRAN 22 and thepacket network 25 under control of theIP BSC 222 at thePCF 223 and realigns compressed data that is transferred through the packet network, whose data rate is adjusted between theRAN 22 and thepacket network 25 to provide the compressed data. Also, theRAN 22 controls the wireless resources of theMS 21 and wireless traffic, controls the handoff, realigns data from/to thepacket network 25 to have interface condition based on the request of theMS 21 to provide to theMS 21, and transfers voice and data to anotherMS 21. - It will be described in detail for one embodiment of the functional model of the
