More specifically, when the network device such as MSC or SGSN performs the paging procedure to check the subscriber's location and serviceability during the basic call processing and proceed to the next step, the success rate and response rate of paging The present invention also relates to a device for paging group management, a call processing method by paging group management, a network device, and a method of driving the device, capable of performing paging in consideration of a load state of a network device.

There are many standards of standards for the global access of mobile communication systems. GSM (Global System for Mobile Communication) is one of the widely used standards. This is regarded as the standard of so-called second generation mobile communication system, followed by the revision of 2.5 generations. General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE) are examples of 2.5G technologies that provide data services at relatively high speeds over GSM networks.

Of course, these earlier standards have been enhanced with additional supplements. In January 1998, the Special Mobile Group (SMG) under the European Telecommunications Standards Association agreed to wireless access plans for a third-generation mobile communication system called Universal Mobile Telecommunications Systems (UMTS). 3GPP was formed in December 1998 to further implement the UMTS standard, and 3GPP is currently studying the next generation of mobile communication standards.

1 is a diagram illustrating a typical 3GPP UMTS system structure.

As shown in FIG. 1, the UMTS network structure includes a UTRAN (UTMS Terrestrial Radio Access Network) 110 and a Core Network (CN) 120 interconnected with the UTRAN 110 via an interface known as Iur. .

The mobile switching centers such as MSC and SGSN manage mobility information of the subscriber in the mobile communication network, that is, MSC or SGSN, in order to enable the mobile subscriber to receive the service normally at any position during or after the movement in the mobile communication network. In this case, the location information of the subscriber is periodically managed.

As a result, when the mobile switching service provides the mobile communication service, the mobile switching center can first check the location information and check whether the subscriber UE can receive the service normally, and then provide the service when the paging is successful.

However, in performing the paging, the conventional mobile switching center first attempts to paging in units of RNC 113 based on previous location information left by the receiving UE, and then attempts to paging in units of MSC or SGSN again when there is no response. The MSC or SGSN is responsible for many RNCs 113, resulting in excessive load on the MSC or SGSN.

In an embodiment of the present invention, the first mobile communication terminal 200 or the second mobile communication terminal 260 (hereinafter, referred to as a mobile communication terminal) of the present invention may be applied to various wired and wireless environments, and is divided into terminal types. PDA (Personal Digital Assistant), cellular phone, smartphone, etc.Personal Communication Service (PCS) phone, Global System for Mobile (GSM) phone, Wideband CDMA (W-CDMA) phone, CDMA-2000 phone, It may include all the MBS (Mobile Broadband System) phone. Here MBS phone represents a mobile communication terminal (200, 260) to be used in the next generation system is currently discussed. Furthermore, the mobile communication terminals 200 and 260 according to the embodiment of the present invention may further be referred to as electronic devices including a desktop computer and a laptop computer.

The mobile communication terminals 200 and 260 may include a wireless communication module and a wireless LAN module, and may further include a GPS module. As the wireless communication module is provided, the mobile communication terminals 200 and 260 access the mobile communication network 230 to perform normal voice call and data communication with the other party. In addition, since the mobile communication terminals 200 and 260 include a wireless LAN module, the mobile communication terminals 200 and 260 may receive various web page data by accessing the wired communication network 240 via the AP 210 recognized in the vicinity. Furthermore, the mobile communication terminals 200 and 260 may be classified into GPS terminals and non-GPS terminals according to whether the GPS module is provided, and when the GPS module is provided, the mobile communication terminal 200 or 260 receives data provided through the GPS satellite 220. .

The mobile communication terminals 200 and 260 are wireless application protocol (WAP), an Internet access protocol, Microsoft Internet Explorer (MIE) based on HTML using HTTP protocol, and handheld device transport protocol (HDPT). Protocol), iT-Mode of NTT DoKoMo, or a wireless Internet connection browser of a specific telecommunication company to access the Internet via the mobile communication network 230. Among the Internet access protocols used by mobile communication terminals 200 and 260, MIE uses m-HTML, which is shortened by slightly modifying HTML, and in the case of i-Mode, compact HTML (c-HTML) which is a subset of HTML. I use the language

In recent years, mobile communication terminals 200 and 260 such as smartphones use a browser for a wireless Internet connection of a specific carrier such as Opera Mini for iPhone, or provide a mobile communication in order to provide faster wireless Internet. Wireless broadband high-speed Internet is provided by using Wi-Fi and WiBro, which are local area networks, together with the terminals 200 and 260.

The AP 210 includes a small base station, such as a femto or pico base station, which is frequently installed in a building. Here, the femto or pico base station is classified according to the maximum number of mobile communication terminals (200, 260) can be connected according to the classification of the small base station. In addition, the AP 210 includes a short range communication module for performing short range communication such as Wi-Fi with the mobile communication terminals 200 and 260. In the embodiment of the present invention, short-range communication is RF and ultra-wideband communication such as Bluetooth communication, Zigbee communication, infrared communication (IrDA), Ultra High Frequency (UHF) and Very High Frequency (VHF) in addition to Wi-Fi. (UWB) and the like can be carried out in various standards. Accordingly, the AP 210 may extract the location of the data packet, specify the best communication path for the extracted location, and forward the data packet to the next device, for example, the mobile communication terminal 200 or 260, along the designated communication path. have. The AP 210 may share several circuits in a general network environment and may include a router and a repeater.

The mobile communication network 230 may include both a synchronous (CDMA) network, an asynchronous (WCDMA) network, a GSM network, and a Long Term Evolution (LTE) network. In the exemplary embodiment of the present invention, any communication network may be used as long as it can perform wireless communication with the mobile communication terminals 200 and 260, and thus the present invention will not be particularly limited thereto.

Among them, for example, the WCDMA network may include a NodeB 300, an RNC 310, an MSC 320, and an SGSN 350 as shown in FIG. 3. Furthermore, the WCDMA network may further include a Visitors Location Register (VLR) 330 and a Home Location Register (HLR) 340. Here, the RNC 310 serves as a kind of auxiliary network device that relays voice or data calls between the NodeB 300 and the MSC 320 or between the NodeB 300 and the SGSN 350. Of course, the NodeB 300 and the RNC 310 in the WCDMA network may be replaced by a base station transmission system (BTS) and a base station controller (BSC) in the case of the CDMA network. In addition, in an Evolved Packet Core (EPC) network, an evolved base station (e-NodeB) and a mobility management entity (MME) may be replaced. The MME is an integrated form of an RNC 310 and an MSC 320 in a WCDMA network. The roles of the RNC 310 and the MSC 320 perform almost the same.

The NodeB 300 is arranged in units of cells, for example, receives a call request signal from the first mobile communication terminal 200 through a traffic channel among signal channels, and receives the received call request. Location registration is performed to transmit a signal to the RNC 310 or to locate the location of the second mobile communication terminal 260 present in the cell area under its control. As described above, the NodeB 300 determines the location of the second mobile communication terminal 260 in its cell area and transmits a call request signal transmitted from the MSC 320 through the RNC 310. In addition, the NodeB 300 is a network endpoint device directly connected to the mobile communication terminals 200 and 260 to perform baseband signal processing, wired / wireless conversion, and transmission and reception of wireless signals.

In addition, the NodeB 300 may obtain information such as latitude and longitude where the NodeB 300 is located by using a signal from the GPS satellite 220, and the location information of the NodeB 300 is transmitted through a system parameter message of the forward link call channel. It may be transmitted to the mobile communication terminal (200, 260). The mobile communication terminals 200 and 260 may register new location information by calculating the moving distance of the mobile communication terminals 200 and 260 by using the location information of the NodeB 300 of the cell to which the mobile communication terminals 200 and 260 belong. Here, the location registration is a processing procedure for notifying the MSC 320 through the NodeB 300 of the location, status, identifier, slot period, and other features of the mobile communication terminals 200 and 260, and the NodeB 300 moves. This is a procedure to effectively call the mobile communication terminal (200, 260) when trying to set the received signal to the communication terminal (200, 260). The location registration of the mobile communication terminals 200 and 260 is performed by the mobile communication terminals 200 and 260 between the MSCs 320 when the power of the mobile communication terminals 200 and 260 is turned on or off. It can be implemented when moving the and when the parameters of the mobile communication terminal (200, 260) is changed.

The RNC 310 controls the NodeB 300, and allocates and releases radio channels for the mobile communication terminals 200 and 260, transmit power control of the mobile communication terminals 200 and 260 and the NodeB 300, and inter-cell soft hands. Soft handoff and hard handoff determination, transcoding and vocoding, GPS clock distribution, and operation and maintenance of NodeB 300 are performed. In addition, the RNC 310 transmits subscriber information of the location-registered mobile communication terminals 200 and 260 to the MSC 320. The RNC 310 transmits a call request signal transmitted from the first mobile communication terminal 200 through the NodeB 300 to the MSC 320, and on the contrary, the RNC 310 transmits a call request signal transmitted from the MSC 320. It serves to deliver to the second mobile communication terminal 260 through the NodeB (300).

The MSC 320 performs basic and additional service processing, reception and outgoing call processing of a subscriber, location registration procedure and handoff procedure, and interworking with other networks. For example, the MSC 320 of the IS-95 / A / B / C system includes an Access Switching Subsystem (ASS) that performs distributed call processing, and an Interconnection Network Subsystem (INS) that performs centralized call processing. It includes a subsystem such as a Central Control Subsystem (CCS), which is in charge of centralizing operations and maintenance, and a Location Registration Subsystem (LRS), which performs storage and management of information on mobile subscribers. In addition, the MSC 320 for 3rd and 4th generation may include an Asynchronous Transfer Mode (ATM) switch. The ATM switch increases the transmission speed and the efficiency of line use by packet transmission of cells. When the MSC 320 performs location registration of the mobile communication terminals 200 and 260 through the NodeB 300 and the RNC 310, the subscriber information of the mobile communication terminals 200 and 260 is temporarily stored in the VLR 330. After storing, the HLR 340 requests the location registration of the mobile communication terminals 200 and 260.

The VLR 330 receives and stores the location information of the visited subscriber whose location information registration is performed from the MSC 320. The VLR 330 temporarily stores subscriber information and notifies the HLR 340 when the mobile communication terminals 200 and 260 perform location information registration, and notify the mobile terminal 200 and 260 from the HLR 340. While receiving and managing a copy of the terminal identification number, terminal unique number and service information of the terminal performs the function to utilize the location control, call processing, external operation processing of the mobile communication terminal (200, 260).

The HLR 340 receives location information of the mobile communication terminals 200 and 260 from the VLR 330 and performs functions such as registration recognition, registration deletion, and location verification. In addition, the HLR 340 stores profile information of the mobile communication terminals 200 and 260 waiting for a call. Here, the profile information refers to a mobile identification number (MIN), an electronic serial number (ESN), or subscribed mobile communication service information of the mobile communication terminals 200 and 260.

SGSN 350 may include a Gateway GPRS Support Node (GGSN). The SGSN 350 manages, manages, authenticates, and manages the mobility of the mobile communication terminals 200 and 260 for the General Packet Radio Service (GPRS) service, a call processing procedure, and a session for handling transmission and reception of packet data. Billing function can be supported. It also has a routing process for packet data. Here, the GGSN is a serving node of an IP-based packet network that provides a high speed packet data service for GPRS. The GGSN performs session management and packet data routing functions for the packet data service, and the mobile communication network 230 and the Internet. It provides an interface for connecting wired communication networks 240 such as networks, GPRS supports 384 Kbps data transmission speed, provides multimedia mail, and asynchronous communication that maximizes transmission line efficiency by packet data transmission. System.

In addition, the SGSN 350 according to the embodiment of the present invention may be the same as in the case of the MSC 320 described above, but the basic call between the first mobile communication terminal 200 and the second mobile communication terminal 260 is called. As a part of the basic call processing procedure, when the call request of the first mobile communication terminal 200 is attempted, paging to the second mobile communication terminal 260 is performed to enable the second mobile communication terminal 260 to make a call. It checks to see if it is in a state. In such a paging attempt, the network devices 320 and 350 according to the embodiment of the present invention may perform a specific RNC (based on previous location information among the plurality of RNCs 310 connected to each of the individual network devices 320 and 350). If paging is performed first with respect to 310, and if there is no response from paging from the second mobile communication terminal 260, the second paging is attempted in a paging group unit in which a plurality of RNCs 310 are grouped. Done.

In order to perform such a function, the network devices 320 and 350 including the SGSN 350 may include, for example, a signal processor 400 and a paging group manager 410 as shown in FIG. 4. . Here, the signal processor 400 processes a voice call or a data call between the first mobile communication terminal 200 and the second mobile communication terminal 260 and paging according to a paging scheme set or changed in the paging group manager 410. Will be performed. The paging group manager 410 may set or change a paging method according to a request or control of the paging group management server 250 in association with the paging group management server 250.

As a result, the signal processing unit 400 receives a signal for the call request from the first mobile communication terminal 200 and transmits the signal to the second mobile communication terminal 260 according to a method set or changed in the paging group management unit 410. Paging will be performed. At this time, the signal processor 400 attempts to page the first RNC 310 based on the previous location information of the second mobile communication terminal 260 provided by the HLR 340, for example, as described above. In this case, paging may be retried in a group unit that forms a group with adjacent RNCs 310 based on the RNC 310 that attempted primary paging.

In addition, the paging group management server 250 according to an embodiment of the present invention further connects to network devices 320 and 350, such as the MSC 320 or SGSN 350, various system load conditions, paging success rate or response rate, etc. The situation may be monitored and a paging group for the RNC 310 may be set or changed based on the monitored information. In this regard, the paging group management server 250 may be provided with the movement pattern information, etc. of the mobile subscribers from a movement pattern management server (not shown), etc., to set and change the paging group for the RNC 310 based on this. will be.

For example, assuming that individual network devices 320 and 350 manage ten to twelve RNCs 310, the paging group management server 250 may provide statistical information or monitoring information on a mobile subscriber's movement pattern. The 12 RNCs 310 may be divided into a plurality of small groups, and the paging group information may be provided to the network devices 320 and 350 to be set or changed. Of course, a plurality of small groups may be formed as one medium group, and paging group information may be provided to the network devices 320 and 350 to be set and changed to further attempt paging for the middle group.

On the other hand, the paging group management server 250 according to an embodiment of the present invention may be provided in the network device 320, 350, such as the MSC (320) or SGSN (350) may be included in the paging group management unit 410. In other words, the paging group manager 410 may be used in the form of a board or a card in which a specific paging group program is set, according to the needs of the system operator. Therefore, the embodiment of the present invention will not particularly limit how the paging group is applied to the network devices 320 and 350.

FIG. 5 is a diagram illustrating an example of forming a paging group by the paging group management server of FIG. 2.

Referring to FIG. 5 together with FIGS. 2 and 3, in FIG. 5A, a plurality of independent small groups are formed for a plurality of RNCs 310 based on the above-described monitoring information or movement pattern information. Indicates. Here, a location area (LA) represents a unit for managing location information in the HLR 340, and a mobile switching center server (MSV) represents a unit of individual network devices 320 and 350, and shaded RNC 2 and RNC. 4 and RNC 10 indicate the RNC 310 related to previous position information of the receiving second mobile communication terminal 260.

In the case of forming a small group as shown in (a) of FIG. By first attempting paging to a specific RNC 310, and if there is no response by attempting a second paging for the group forming a small group with the adjacent RNC 310, including the RNC 310 attempted the first paging In the paging attempt, the load generated by the network devices 320 and 350 may be reduced.

As shown in FIG. 5A, FIG. 5B forms a plurality of small groups based on monitoring information or movement pattern information, and in the case of a specific RNC 310, is formed to be included in two small groups. . In this case, for example, when the network device 320 or 350 attempts to page the second mobile communication terminal 260 on the receiving side, the network device 320 or 350 may be used as a primary for the specific RNC 310 based on the previous location information registered in the HLR 340. If paging is attempted and there is no response, paging may be attempted once again for the RNC 310 that attempted primary paging. For example, if the second mobile communication terminal 260 is in a shadowed area where no signal is received at the first paging attempt, and is out of the shadowed area at the second paging attempt, the response success rate is increased as compared to the case of FIG. Will be done.

Furthermore, in the method of forming the RNC paging group according to the embodiment of the present invention to include the RNC 310 overlapping each other as shown in (b) of FIG. 5, for example, the individual network devices 320 and 350 may be If the eleven RNCs 310 are in control, the RNC paging group forms two small groups of five and six RNCs 310 each as a group, where the RNCs 310 are in the range of two to four. It may be possible to form overlapping. Since this can be changed according to what information is set on the basis of the group, as mentioned above, the embodiment of the present invention will not particularly limit the method of setting such an RNC paging group.

FIG. 6 is a diagram illustrating a call connection process of an apparatus for managing paging groups of FIG. 2.

Referring to FIG. 6 together with FIGS. 2 and 3, first, the paging group management server 250 accesses network devices 320 and 350 such as the MSC 320 or the SGSN 350 to request management of the paging group. (S601). Here, the request for management may mean that the network device 320 or 350 is provided with a paging group related program to be set or changed to a predetermined program.

As described above, the network devices 320 and 350 set or change the paging group according to the paging scheme provided by the paging group management server 250 (S603).

Thereafter, when the first mobile communication terminal 200 requests a call to the second mobile communication terminal 260 (S605), the network devices 320 and 350 receive a signal for the request.

The network devices 320 and 350 provide and set or change the paging group management server 250 when a call connection is attempted with the second mobile communication terminal 260 according to a request of the first mobile communication terminal 200. Paging is attempted according to the group method (S607).

For example, the network devices 320 and 350 according to an embodiment of the present invention first attempt to page the corresponding RNC 310 based on the previous location information of the second mobile communication terminal 260, and then the second device. If there is no response from the mobile communication terminal 260, the secondary paging is attempted in the RNC paging group unit managed by the paging group management server 250.

In this case, if there is a response from the second mobile communication terminal 260 (S609), the network devices 320 and 350 connect the calls of the first mobile communication terminal 200 and the second mobile communication terminal 260 with each other ( S611).

If there is no response from the second mobile communication terminal 260 even when the second paging attempt is attempted, the network devices 320 and 350 may retry paging according to a method of forming a small group paging group in a medium group unit. There will be. Since it has been described above, further description will be omitted.

According to this process, the network devices 320 and 350 according to the embodiment of the present invention can flexibly manage network resources such as the RNC 310 when paging to the second mobile communication terminal 260 on the receiving side. Furthermore, the response success rate can be increased.

FIG. 7 is a diagram illustrating a driving process of the network device of FIG. 4.

Referring to FIG. 7 together with FIGS. 2 and 3, first, the network devices 320 and 350 set an RNC paging group or change a preset paging group according to the management of the paging group management server 250 of the RNC 310. (S701).

Subsequently, when the network device 320 or 350 requests a call for the second mobile communication terminal 260 of the first mobile communication terminal 200, the network devices 320 and 350 move to the second mobile communication terminal 260 according to a set or changed RNC paging group method. Paging is attempted (S703).

In this case, if there is no response from the second mobile communication terminal 260, the network devices 320 and 350 try to paging once again according to the method in which a plurality of small groups are formed into the middle group again, or the entire RNC group, that is, the individual network devices.
