The mobile call manager (MSC) describes the terminal location registration, the wireless section call control, the wired section voice call control and voice path setting, and the packet data path setting as follows.

One). Terminal Location Registration (HLR: Home Locaticn Register) and Radio Section Call Control of Mobile Call Agent (MCA) 220

The mobile terminal (MS) 101, 102 receives the control information signal of the base station 201 and knows the location information of the currently connected terminal. If the location information is changed or needs to be registered according to other location registration requirements, the location The registration message is sent to the base station (BTS).

At this time, the base station (BTS) transmits the location registration message of the mobile terminal (101, 102) to the base station controller (BSC), the base station controller (BSC) to the mobile call manager (MCA), the mobile call manager is a mobile terminal (101, 102) It updates the location information of and transmits the updated information to Packet Routing Control (PRC) and Call Control Agent (CCA).

When the mobile terminal 101 or 102 requests a voice call or packet data service, the mobile call manager (MCA) / beester location register (VLR) allows a call connection through an authentication process, and the voice channel occupancy and packet of the wireless channel are allowed. After allowing the channel to be occupied, the wireless terminal connection state of the mobile terminal is preserved and managed.

2). Wired Segment Voice Call Control and Voice Routing for Mobile Call Manager

When the mobile terminal 101, 102 makes a voice call, a forwarding link for the transmission of a wireless voice packet between the mobile terminal 101, 102 and the base station controller (originationg BSC) is established and terminated at the origination BSC. The wireless voice packet of the terminal is transmitted to the trunk gateway (TG) 230 in the case of a call with a wired subscriber according to the called party's location, and the voice of the call is converted into a PCM voice signal at the trunk gateway (TG) 230 to be converted into a PSTN. It is connected to the incoming subscriber of the / PLMN (Public Switched Telephone Network / Public Land Mobile Network) 320 by a line.

In addition, a Radio Call Control (RCC) signal allocates a channel for delivering voice packets to a trunk gateway (TG) 230 in a mobile call manager (MCA), and a signal with a PSTN / PLMN 330 is a mobile call. The manager (MCA) transfers the signal processing gateway (SG) 231 to the signal processing gateway (SG) 231 for signal interworking with the public network (PSTN / PLMN) 320 for call setup to the called subscriber. .

And, when connecting to a wireless terminal in the same operator, the mobile call manager (MCA) transmits a control signal to the terminating base station controller (terminating BSC) of the base station where the destination terminal is located, and the voice packet is delivered to the terminating base station controller It is delivered to the base station controller and the destination terminal.

When connected to a wireless terminal in another provider network, a signal of a mobile call manager (MCA) is transferred to an intercarrier gateway (IGG) 233 connected to the corresponding operator network, and a voice packet is also transmitted to the intercarrier gateway (ICG). The signal is transmitted to the mobile call manager (MCA) in which the called terminal in the 3G All IP Network 310 is located. At this time, the voice packet is delivered to the base station controller (BSC) of the base station (BTS) where the destination terminal controlled by the mobile call manager (MCA) is located and is wirelessly connected to the destination terminal.

3). Packet Data Path Settings for Mobile Call Manager

When a terminal subscriber connects to a terminal 102 connected to a computer or the like to execute a packet data service, a radio channel packet is transmitted from the packet data terminal 102 to a wireless base station (BTS) 201 and a base station controller (BSC), The packet data selected by the base station controller (BSC) is transferred to a packet control function (PCF), the PCF is transmitted to a packet data serving node (PDSN), and the PDSN 240 is connected to the Internet / Internet to access the mobile terminal. It becomes a service.

Here, a Point to Point Protocol (PPP) link is established between the mobile terminal 102 and the PDSN, and the packet data service state is inactive until the mobile terminal is powered down or by another method. It is necessary to ensure that the PPP link of 102 is maintained with the first registered PSDN.

To this end, a packet routing controller (PRC) of a mobile call manager designates a PSTN to which a mobile terminal connects when requesting packet data service from an initial mobile terminal, and the mobile terminal 102 determines a base station 201 and a base station controller ( When moving to another new BSC / PCF 212 area in a dormant state that does not have a wireless traffic channel with the BSC), the mobile terminal is determined from a registration message according to a location registration message or a packet zone change of the terminal. Detect that the position shift of has occurred.

Then, the mobile call manager informs the previous BSC / PCF that was previously serviced to move the mobile terminal to remove the registration status of the mobile terminal stored in the previous PCF, and informs the new BSC / PCF that the mobile terminal has moved. Subject removes the registration status of the mobile terminal previously stored in the PCF.

In addition, it informs the new BSC / PCF that the mobile terminal has visited, and transmits the information of the serving PDSN of the mobile terminal so that the new PCF and the serving PDSN establish the RP (Radio-PPP) link, thereby providing a PPP link between the mobile terminal and the serving PDSN. Is to be kept constant.

The packing routing controller (PRC) manages the serving PSDN ID of the mobile terminal, the active / inactive packet data service of the mobile terminal, the serving PCF ID, and so on. It provides packet routing information of the mobile terminal to / PCF.

The mobile call manager (MCA) has mobile terminal mobility control, call control, radio resource allocation state control, and wired network connection control of the mobile switching center 341 together with one integrated wired / wireless control function. Core network) and wireless access network function elements together, there is no clear distinction between wired and wireless segments in All IP, so access network elements and core network elements are not separated and other access networks This is a disadvantage when accepting IP core networks.

However, in the All IP network as shown in FIG. 1, since all network elements are connected to one integrated IP network without being separated into a wireless network and a core network, an IP core network is established and various access networks In case of integrating the system, it is inefficient for duplication or management of network elements.

In addition, data and signals transmitted between radio sections (base stations and base station controllers) require real-time transmission for the purpose of soft handoff and power control of the cdma 2000 system, whereas the core network does not require a relative real-time response. Mixed with non-voice packet data of IP, complex management operation and quality of service (QoS) management in case of using IP network, especially when wanting to accept other kinds of access network in All IP core network Guaranteeing real-time quality of service (QoS) between the base station and the base station controller is difficult.

The present invention has been made to solve the above-mentioned problems, and the All IP network is divided into an IP core network and a wireless access network, and the all IP core network can be connected to various types of access networks. While the core network element is used in common regardless of the type of the access network, the mobile call manager is a wireless control manager (WCA) which is a wireless network dedicated element and a wired call manager (TCA) which is a wired network line access control element. The purpose of the present invention is to provide an all IP network operating system and a method of operating a mobile communication system for separating and operating an IP wireless access network control and an IP core network.

That is, the IP core network 600 includes a home location register (HLR) 540, a radio control manager (WCA (MM / RCC / PRC)) 531, a wired call manager (TCA (CSCF)) 532, a base station Controller / PCF 520, PDSN 556, signal processing gateway (SG) 553, trunk gateway (TG) 554, voice server (VS) 555, intercarrier gateway (ICG) 551, Network elements such as an intergeneration signaling processing gateway (IGSG) and an intergeneration trunk gateway (IGTG) 728 are configured.

The operation of the outgoing voice call of the mobile terminal in an all IP network may include;

For the call origination of the mobile terminals 501 and 502, the wireless base station (BTS) 510 receives the origination request message and transmits it to the base station controller (BSC) 520 through the IP field (RAN) 601 to transmit the call request message to the base station controller ( When the BSC 520 requests the wireless control manager (WCA) 531, the wireless control manager (WCA) 531 executes authentication of the terminal through the home location register (HLR) 540 and permits wireless connection. The base station controller (BSC) 520 then allocates radio resources and requests radio packet frame data delivery.

Then, a traffic channel between the mobile terminals 501 and 502 and the BSC / SDU is established by allocating a transmission resource between the radio base station-base station controller (BTS-BSC). When the wireless control manager (WCA) 531 requests the voice call setup of the mobile terminal to the wired call manager (TCA) 532, the wired call manager (TCA) 531 determines the mobile terminal according to the called party information of the voice call. The voice call is connected to the mobile terminal and the called party by allocating for call setup with the serving BSC / SDU and the called party's TG / ICG / BSC and performing signaling.

Here, the soft handoff of the mobile terminal is fixed to the BSC / SDU, so that the wired call manager (TCA) 532 is not involved, and the wired side voice traffic bearer connection of the IP core network 600 does not change. maintain.

In the case of hard handoff to change the base station controller (BSC) of the mobile terminals 501 and 502, the wireless control manager (WCA) works with other wireless control managers to process handoff signaling of the mobile terminal and then wire By transferring handoff BSC / SDU information to the call manager (TCA) and requesting handoff reconnection, the wired section call connection is changed and set.

For packet service calls; As the mobile terminal requests the packet data service option, the wireless control manager (WCA) 531 permits the wireless connection of the terminal through the home location register (HLR) 540, and the PDSN ID to which the mobile terminal 502 is connected. To the BSC / PCF 520.

The base station controller (BSC) allocates radio resources for packet service of the mobile terminal according to the authorization of the radio control manager (WCA), and the PCF 522 transmits path information of the PDSN 556 to which the mobile terminal 502 is connected. When the PCF 522 establishes an RP link to the designated PDSN 556, the PPP link is established between the mobile terminal 502 and the PDSN 556, and the Internet access client S / W of the mobile terminal 502 is transmitted. The PDSN 556 manages visiting subscribers of the mobile terminal 5020 and performs Internet (or intranet) connection according to the scheme of FIG. 640).

Here, the home agent (HA) serves as a gateway for accessing the mobile IP user, and the AAA (Authertication, Authorization, and Accounting) server performs authentication, authorization verification, and charging for the user.

In the case of a hard handoff in which the mobile terminals 501 and 502 change the BSC / PCF 520, the wireless control manager (WCA) 531 provides a serving PDSN ID to the new BSC / PCF when the handoff is completed, thereby providing a new PCF. By establishing the RP link with the serving PDSN, the Internet packet link is continued without re-establishing the PPP link, the IP can continue to be used.

When the mobile terminals 501 and 502 move to another new BSC / PCF in a DORMANT state in which the packet bearer channel between the radio traffic channel and the BSC-PCF has been released, the wireless call manager (WCA) 531 determines that the packet of the mobile terminal Detect that the location change has occurred by automatic registration or other location register due to the area change, and the mobile terminal sends a message including the serving PDSN ID to the new BSC / PCF, so that the new PCF and the serving PDSN open the RP link. In addition, the location update information of the mobile terminal is transmitted to the previous BSC / PCF including information called DORMANT handoff, so that the RP link information and the RP link stored in the previous PCF are released early.

4 is divided into a wireless call manager (MCA) and a wireless control manager (WCA) and a wired call manager (TCA) to handle the wireless section control function and the wired section call connection, and separated into an IP column and an IP core. Various wired and wireless access networks (2G RAN, cdma 2000, other RAN) (3G / All IP Carrier, PSTN / PLMN, Internet / Intranet / ISP, Fixed Access Network) simultaneously from All IP network to Core IP network In this case, the wired call controller wired call manager (TCA) can be used as a home wired call manager (TCA) of another access network subscriber.

As described above, in the operation of the All IP network of the mobile communication system according to the present invention, wireless access for data access between the IP core network and the mobile communication terminal to access various types of access networks All IP networks are divided by network and each network element is separated, allowing core network elements to be connected in common regardless of the type of access network, so that other access networks can be accommodated in IP networks or various access networks. In case of integrating them, it is effective to exclude duplication of network elements and to facilitate management.

In addition, by separating the wired network call control function and the wireless access network control function, and clearly distinguish the wired and wireless interval, it is possible to facilitate the management operation of the IP network when using the IP network mixed with non-voice packet data.
