The technical field to which the invention relates

This invention relates to a cellular network, in particular to a system that creates a subnet-based Internet Protocol aboard aircraft in the onboard wireless cellular network.

The level of equipment

In wireless communications, there is a problem in the manage wireless services provided to aircraft network passengers on the plane when they move between base stations in cellular network. This aircraft network serves many subscribers and has a line with terrestrial network via a broadband connection, which serves at the same time many individuals. The task of managing this broadband connection that provides individual identification aboard subscribers, has yet to decide in existing wireless networks.

In the field of cellular communication wireless subscriber usually moves in the areas served by the network, the provider of mobile services, and saves your desired subscriber set of functions. The availability of a set of functions through its network is controlled by its own database provider of mobile services, often referred to as registry own subscribers (HLR), with data connections with one or more switches (batch or channel) and with various accessories, such as voice mail, servers short messages to ensure inextricably management of this set of functions. Every subscriber is associated with one-to-one connection, which contains the channel on the database to access the desired service.

If the wireless subscriber had to pass between the networks of the region meet its own cellular network to the network of the same or another provider of cellular services (called the «provider of cellular roaming services»), this wireless subscriber should have the ability to initiate and receive calls uniformly, regardless of location. In addition, it ought to be possible in a transparent manner to move the set of functions of this wireless subscriber with him. But to have this chance of moving a set of functions that need to be available for sharing a database file in which the registry own subscribers (HLR) private mobile services transfers authorized profile feature set of the subscriber database provider of cellular roaming services, often referred to as the registry of roaming subscribers, or VLR. Then VLR recognizes that the roaming wireless subscriber has the right on some set of functions and allows the service provider's network of cellular roaming services transparently to offer these features wireless subscriber. While roaming wireless subscriber keeps the same authorized functions, or «subscriber category, which he had in his own network provider of mobile services.

When wireless subscribers are the cellular network (that is, they fly in the plane as passengers), they are confronted with a unique environment that has traditionally been disconnected from terrestrial cellular networks and wireless LAN aircraft ensures the interaction of the subscriber (also called «passenger») with a variety of services and content. Therefore aircraft wireless network can function as a content filter or can create unique content types, which are directed to individual passengers that are on Board of the aircraft. However, although aircraft network service a large number of passengers, it has a line of communication with ground-based network access through a broadband radio frequency connection, which has a single IP address in terrestrial network access. Thus, broadband wireless connection simultaneously communication takes many individual passengers, but these relations can not be identified separately terrestrial network access. In existing wireless networks still need to deal with the control of this broadband connection to provide the individual identification of passengers through the appointment of a separate, unique IP addresses to each passenger wireless device.

Disclosure of the invention

The above problems are resolved and technical progress in this field achieved by this system to control addresses the mobile Internet-Protocol on-Board wireless cellular network (called here the «plane IP address of a mobile Internet Protocol»)which provides for the assignment of individual addresses the Internet Protocol (IP address) each passenger wireless devices in aircraft and aircraft serviced wireless network, which allows us to deliver wireless services individually identifiable passenger wireless devices.

Aircraft system IP address of a mobile Internet Protocol provides wireless services to passengers that are on Board of the aircraft by memorizing data pointing individually identified the wireless devices that are on Board of the aircraft. Aircraft system IP address of a mobile Internet Protocol assigns a single IP address, or each modem «air-earth» block communications «air-earth», which completes the radio frequency line connecting aircraft network with terrestrial network access or mobile IP (MIP) the client is executed on the host processor «air-earth», located for these modems «air-earth». The third approach is to avoid the use of mobile IP client and use simple IP addresses and IP tunnel to connect aircraft network with terrestrial network access. This approach does not change the ICPC or other EVDO protocols/notifications, but still allows the terrestrial network access directly see private IP address of the wireless device.

E-services provided to the passenger, include the Internet, flight of the services activities, such as multimedia presentations, as well as services based on the destination that bind passenger plans for this trip offers additional services that are available for passengers in its principal place of destination, and the planned schedule of the trip, and, optionally, voice services. Thus, the passenger is offered the opportunity during his flight to expand their knowledge, both in flight and at the place of destination, by reference to a variety of services. Individual identification of each passenger wireless device simplifies the provision of these services and allows individualization of these services on a pre-defined profiles created by the passenger.

Detailed description of the invention

The overall system architecture

Figure 1 illustrates in the form of a block diagram of the overall architecture cellular network, which includes a network of 2 «air-earth» (internal network), which connects the two elements external network containing air subsystem 3 and ground-based sub-system 1. The diagram illustrates the main ideas cellular network and for the purposes of simplicity, the illustrations do not include all the elements present in a typical cellular network. Disclosed in figure 1, the main elements provide a view of the relationships between the different elements which are used for the realization of cellular network to provide content passenger wireless devices located in the plane.

The General idea is illustrated in figure 1, is to ensure «the internal network, which connects the two segments «external network», which contain air subsystem 3 and ground-based sub-system 1. This is ensured by the network 2 «air-earth», as transmitting traffic passenger communication (containing speech and (or) other data, and control information and data set of functions between the air subsystem 3 and ground-based subsystem 1, making passenger wireless devices that are located in a plane, can receive services in the plane.

Air subsystem

«Aircraft engine» is a communication environment, which is implemented in the plane, and this relationship can be based on different technologies, including but without limitation them: wired, wireless, optical, acoustic (ultrasonic) and the like. An example of such network uncovered in U.S. patent number 6788935 entitled «Aircraft network for wireless subscriber stations».

The preferred option for air subsystem 3 is the use of wireless technology and the wireless technology, which is native for passenger wireless devices, which passengers and crew are on the plane. So, a laptop computer can communicate through wireless WiFi or WiMax (either through a wired connection, such as a LAN), or a personal digital assistant (PDA) can transfer telephone voice traffic via voice transmission over IP (VoIP). Similarly, a mobile phone that uses the GSM Protocol, communicates through global system for mobile communications (GSM)from inside the plane, air subsystem 3. Cell phone multiple access code division multiple access (CDMA) will use CDMA and analog telephone superior mobile phone service (AMPS)from inside the plane, will use the analog AMPS with air subsystem 3. Connection status will be packet-switched or circuit-switched, or both, and more. Ultimately, the purpose of air subsystem 3 is to ensure continuous and ubiquitous access to air subsystem 3 for passenger wireless devices that carry passengers and crew, regardless of the technology used in these devices.

Air subsystem 3 provides a mechanism for management services passenger wireless devices that operate in the cabin. This management includes not only the provision of connectivity passenger traffic, but also the availability specific sets of functions that each passenger is allowed to take. These functions include the flight entertainment services, such as multimedia presentations, as well as services based on the place of destination, which connect the existing passenger travel plans with proposals of additional services that are available for passengers in its principal place of destination, and with its planned schedule of the journey. Thus, the passenger is offered the opportunity to improve during the flight, their impressions of the trip, as during the flight and at the destination.

Passenger wireless devices 101, used in aircraft, may be identical to those used in cellular/PCS terrestrial network connection; however, these passenger wireless devices 101 register in advance with the carrier, serving the aircraft, and (or) users have non personal codes for identification. In addition, the antenna connects the passenger wireless devices 101 (base transceiver system (BTS) 111-114 in the salon, which are, as a rule, with built-in functions BSC/MSC. Modules BTS/BSC/MSC added for each supported technologies of air interface. Switch/router 122 acts as a bridge functions (for media content and signaling to a limited extent) between the air subsystem 3 and terrestrial network-1 security, since a switch/router 122 makes a call using a modem 123 in the terrestrial network 1 networking 2 «air-earth». Switch/router 122 converts individual channels of traffic and service signals from base stations in the aggregate data flow or from the aggregate data flow and transmits/receives aggregate data streams through the network 2 «air-earth», which maintains continuous service with the flight of the aircraft. Modem 123 includes the hardware of the radio and antenna systems for communication with ground-based transceivers in terrestrial network part 2 «air-earth». Individual channels of traffic, dedicated network 2 «air-earth», are enabled based on the needs in traffic intended for the support of the plane.

Network «air-earth»

Network 2 «air-earth», shown in figure 1, is, of course, network, which is based on wireless communication (radio or optical) between ground subsystem 1 and passenger wireless devices 101, which are located in the plane, while it is preferable that the network was based on the radio connection. This wireless connection looks cellular topology, where, as a rule, several hundred describe a geographical spot, or the coverage zone composite network 2 «air-earth». Connection «air-earth» takes as passenger traffic connection and traffic service signals inherent in the network. In a preferred embodiment, network 2 «air-earth» takes all traffic to and from the aircraft and from him in the only comprehensive communication channel. This is «the only pipeline» has the significant advantages from the point of view of management of hardware and software handovers, when the aircraft is moving from one land cell to the next. This approach also gives the advantage of the new high-speed wireless cellular technology.

Alternative, network 2 «air-ground» can be controlled via a wireless satellite connection, where radio-frequency lines of communication are established between the aircraft and satellite and between satellite and ground-based subsystem 1, respectively. These satellites can be geosynchronous (seemingly stationary relative to the earth) or moving, as in the case of medium earth orbit (MEO) or low earth orbit (LEO). Examples satellites include, but are not limited to: geosynchronous satellites in sub-band frequencies «Ki», the direct broadcasting satellites (DBS), Indium, Globalstar and Inmarsat. In the case of specialized satellites, such as those used for direct broadcasting satellites, communication line, as a rule, is unidirectional, i.e. from the satellite to the admissions platform - in this case, to the plane. In such a system need a line of communication, leading one-way transfer from the aircraft to make the bilateral relationship. This communication line can be satellite or terrestrial, wireless in nature, as described previously. Finally, other means to communicate with aircraft include lines of communication over a larger area, such as high-frequency (HF) radio, and more unique systems such as architecture tropospheric scatter.

Network 2 «air-ground» can be seen as a pipe between the ground subsystem 1 and air subsystem 3 tolerated passenger traffic communication, such as control data and network functionality. Network 2 «air-ground» can be implemented as a single radio frequency communication line or multiple-frequency communication lines, some signals are routed on the various types of communication lines, such as line, «air-ground and satellite line. Thus, there is considerable flexibility in the implementation of this system using a variety of components and architectural ideas, revealed here, in various combinations.

RF structure for modem «air-earth», as a rule, uses many modems where one modem «air-earth» (modem 1 «air-earth») is working with vertical polarization signal, and the other modem «air-earth» (modem 2 «air-earth») operates with horizontal polarization signals, and as the intensity of the signal is lost/accrues in a separate modems «air-earth», this modem «air-earth» goes idle or active.

In the first variant of the implementation of this Protocol modems «air-earth» not assigned IP address, but there is mobile IP client in connection unit «air-earth» direct address to the public switched data network for General use. This mobile IP client is made with its own address and registered with the relevant external address/private address to associate own address with the modem 1 «air-earth» or modem 2 «air-ground» in the public switched data network for General use/external addresses. Communication own address with the address for transmission (subnet address) is not changed because the address to send the address represents the IP address of the public switched data network for General use and is controlled in the public switched data network for General use. Mobile IP client in connection unit «air-earth» requires information from the modem «air-ground» to update the mobile IP bindings external address/home address. Mobile IP client 413 should take a dedicated IP modem 1 «air-earth» and modem 2 «air-earth» (this is the address to send to mobile IP client). Mobile IP client must be configured/known own address and the server address of the private agent. This configuration can run multiple mobile IP client and tunnels communication unit «air-earth».

In the second version of the Protocol, each modem «air-earth» is assigned an IP address, and mobile IP client remains in the control processor «air-earth». This mobile IP client is made with its own address, and the address for transmission associated with a modem and a 1 «air-earth» or modem 2 «air-earth» block communications «air-earth». Mobile IP client in the host processor «air-earth» is connected via mobile IP tunnel with the public switched network of public data. Traffic switches between modems «air-ground»when the signal strength is lost/accrues in a separate modems «air-earth».

In the third variant of the Protocol, each modem «air-earth» is assigned an IP address, and simple IP addresses are controlled in connection unit «air-earth». Set the IP turrets connect the control processor «air-ground» with the router in terrestrial network access. Control processor «air-earth» functions as the destination of the tunnel and uses the address common use for these IP tunnels. Traffic switches between modems «air-earth, when the intensity of the signal is lost/accrues in a separate modems air-ground».

Ground subsystem

So, the relationship between passenger wireless devices 101, located in aircraft, and ground-based subsystem 1 landline networks is transmitted through the air subsystem 3 and network 2 «air-earth» ground controllers 141 base station cellular network. Advanced features described below and provide air subsystem 3, network 2 air-to-ground and ground controllers 141 base station, ensure the provision of passenger wireless devices 101, located in the plane, transparent to the passengers. The radio access network (RAN) supports communication from a variety of aircraft and can apply only omnidirectional signal, or you can apply multiple spatial sectors, which can be defined as the angles of azimuth and tilt. Aircraft networks carry the service lines from point to point between the radio access networks (RAN) in different locations (the various ground-based subsystems 1)to maintain the continuity of services in network 2 «air-earth». Transfer service can be either hardware or software, or it may be a hardware and software combination in the lines «air-ground» and «air-ground».

Mobile switching center (MSC) provides management of mobility for all onboard systems and provides management transfer between ground stations, aircraft when the system is moved between service areas adjacent land subsystems 1. The controller base station (BSC) matches all traffic to base transceiver subsystem (BTS) or from it. Site maintenance package data (PDSN) manages the allocation of capacity of each of the base transceiver subsystem (BTS) from onboard systems in their respective service areas.

Typical onboard aircraft network

Figure 2 illustrates the architecture of a typical onboard aircraft network for passenger wireless devices, as it is embodied in multi-seat commercial aircraft 200. This system contains many elements that are used to implement trunk line, which is used to provide wireless connectivity for a wide variety of wireless devices of various kinds. Onboard of the airplane network for passenger wireless devices contains a local network 206, which includes a system 201 radio frequency communications, which uses the schema extended range and short-range performance. This network 206 supports connections with both circuit-switched and packet switched from passenger wireless devices 221-224 and connects the link from these passenger wireless devices 221-224 through a lock transceiver or transceiver 210 to the public switched telephone network 126 (PSTN) and other destinations, such as the Internet 127 or public switched data network of General use (PDSN). Thus wireless passengers retain his only ID number, as if they were directly connected to the public switched telephone network 126 General use. Passenger wireless devices 221-224 include a variety of communication devices, such as portable computers 221, cell phones 222, music players MDE (not shown), personal digital assistants (PDA) (not shown), devices, 223 on the basis of WiFi devices 224-based WiMax and the like, and for ease of description all of them together are called here «passenger wireless devices,» regardless of the specifics of their implementation.

The main elements of the onboard aircraft network for passenger wireless devices contain at least one antenna 205 or the connection tool of electromagnetic energy for air subsystem 3 or from the air subsystem 3, located in 200 aircraft, which is used for communication with many passenger wireless devices 221-224, located in 200 aircraft. This at least one antenna 205 connected with a wireless controller, 201, which encompasses many elements that serve to regulate wireless communications with multiple passenger wireless devices 221-224. Wireless controller 201 includes at least one low power RF transceiver 202 to provide space communication packet switching using, for example, such a scheme wireless as PCS, CDMA or GSM. In addition, a wireless controller 201 includes low power RF transceiver 203 to provide space communications with switched-based packet data, using such a scheme wireless communication such as WiFi (which can also send a voice-over-Internet Protocol packet switched (VoCP)). Finally, a wireless controller 201 includes segment 204 power control, which is used to control the output power of many passenger wireless devices. He is also, by means of devices of radio-frequency noise suppression to protect passenger wireless devices from direct and erroneous references to the terrestrial network in mode. Function low transmit power levels on Board the aircraft represents the item 204 power control wireless controller 201 onboard aircraft network for passenger wireless devices so that regulate power output signal passenger wireless devices 221-224, to minimize the probability of reception of cell signal ground base stations or terrestrial wireless devices.

Obviously, these above-mentioned segments of the wireless controller 201 can be combined or broken in various ways to obtain and implementation, which differs from the disclosed above. Describes the specific embodiment selected for the purposes of illustration ideas of the invention and is not intended to limit the applicability of this idea to other incarnations.

Wireless controller 201 connected via a network backbone 206 with many other elements that are used to provide passenger services wireless devices 221-224. These other elements may include aircraft interface 209 (which includes «Block communications «air-ground» and «control processor «air-earth») to provide the control, switching, routing and aggregation for the transmission of communications passenger wireless devices. Item 207 obtain the data is used for interfacing with multiple sensors 211-14 flight system and element 216 global positioning system to collect data from multiple sources, as described below. Further, with this basic network 206 connected through a wired connection or wireless connection communication devices pilot, such as display 217 and headphones 218.

Finally, for connecting aircraft interface 209 to the antenna 215 is a gateway(s) transceiver(s) 210 to ensure the transmission of signals from aircraft network for passenger wireless devices 221-224 to the transceivers located on earth. In these components is enabled router due to direct communications signals to the required destination. Thus, the signals that are designed for passengers on the plane are routed to these persons, while the signals are routed to the passengers are located, for example, on earth, are routed in the land-based subsystem. In the implementation of the antenna (antenna) 215 by plane, you can use a combination of aircraft antennas, which, as a rule, minimize effective radiated power (EPR) in Nadir (in the direction of the Earth)to service aircraft network for passenger wireless devices 221-224.

Registration of passenger for system access

For ease of description, the following examples are based on the use of variants of cellular networks CDMA2000 EVDO. However, as illustrated here the idea is not limited by this implementation, and it is assumed that other implementations can be created on the basis of other network architectures and implementations. So figa and 3B show the form of a block diagram of the architecture typical of the cellular network EVDO for transmission of IP and data services for IP transmission, respectively, and are used to illustrate the architecture and operation of this aircraft mobile system of IP addresses. CDMA2000 is a hybrid 2.5/3 generation of mobile telecommunications, which uses multiple access code division multiple access (CDMA)to transmit digital signals radio, voice, data and ancillary data between wireless devices and base stations. The architecture and operation of cellular networks CDMA2000 standardized Project 2 third generation partnership (3GPP2). In cellular networks CDMA2000 supported two technologies radio access network: IxRTT and EV-DO (optimized evolution data), and CDMA2000 is a third generation technology when you use the network access EV-DO.

The network CDMA2000 (referred to here as the «network access») contains three main parts: the core network (CN), the radio access network (RAN) and a wireless device (MS). Core network (CN) is further divided into two parts, one of which interacts with external networks such as the public switched telephone network (PSTN), and interacts with other network based on the Internet Protocol, such as the Internet 311 and (or) private network 312 data. Wireless device MS completes the path on the user side of the cell network and allows subscribers to access network services through the interface Um, implemented for connection of the wireless device (MS) with a network of 300 access.

Several key components of a network of 300-only access to IP data, as shown in figa are:

- Base transceiver system (BTS): an object that provides the function of transmission through reference point Um.

- Base transceiver system (BTS) consists of radios, antennas and equipment.

Controller base station (BSC): object, which provides management and control for one or more base transceiver system (BTS).

Function package management (PCF): object, which provides a network interface with the switching of packages (Internet 311 and (or) private network 312 data).

A wireless device (MS) is acting as mobile IP client. A wireless device (MS) communicates with a network of 300 access to appropriate radiorecord to exchange packets and monitors radio resource (for example, active, standby, hibernate). A wireless device (MS) takes the buffer packets from the base transceiver system (BTS)when radiorecord are not in place or are inadequate to maintain flow to the network of 300 access. When enabled wireless device (MS) is automatically registered in the registry of private subscribers (HLR) in the mobile switching center (MSC) in order to:

- to authenticate wireless device (MS) for the network medium, and which makes the access;

- to provide the registry own subscribers (HLR) the current location of the wireless device;

- to provide service mobile switching center (MSC)is allowed functions of the wireless device.

After successful registration in the register of private subscribers (HLR) wireless device (MS) ready to install voice calls and data calls. They can take either of two forms - transfer circuit switched data (CSD) and the transmission of data by packet switching (PSD), depending on compliance (or lack thereof) of the wireless device to the standard is-2000.

Wireless device must match the standard is-2000, to initiate the transmission of data packets through the network of 300 access. Wireless devices that only have the function is-95, is limited by data transmission is switched on switched telephone network (PSTN), while the terminal is-2000 can choose to either transfer data by packet switching, or data transmission with the channels switching. The parameters sent wireless device (MS) for aerial communication lines (AL) in the network of 300 access, determine the type of the requested services. For each session data session is created Protocol point-to-point connection (PPP) between a wireless device (MS) and the serving host packet data (PDSN). Assigning an IP address to each wireless device may be provided either by the serving host packet data (PDSN), or the server dynamic host configuration Protocol configuration head machine (DHCP) via its agent (ON).

The radio access network (RAN)

The radio access network (RAN) is the entry point wireless transmission or data, any language content. It consists of:

Air lines (AL);

- Towers/antennas, base stations and cable connections to base transceiver subsystem (BTS);

- Basic transmission subsystem (BTS);

Path from the base transceiver subsystem to the controller base station (BSC);

Base transceiver subsystem (BTS) controls the action of air communication lines (AL), and acts as an interface between a network of 300 access and wireless device (MS). Radio frequency resources, such as the allocation of frequencies, the division into sectors and management of power transmission by base transceiver subsystem (BTS). In addition, base transceiver subsystem (BTS) controls the back of the base station controller base station (BSC), in order to minimize any delays between these two elements.

The controller base station (BSC) routes the voice mail and data messages with switching circuits between base stations and mobile switching center (MSC). He is also responsible for managing mobility: it controls and directs transfer service from one base station to another as needed.

Function package management (PCF) routes IP packet data between a mobile station (MS) in base stations and service node packet data (PDSN). During the session packet data, it assigns available additional channels as needed to fit to the services requested wireless device (MS) and paid subscribers.

Serving a host packet data (PDSN)

Serving a host packet data (PDSN) is a gateway from the radio access network (RAN) in public (or private network packet. In simple IP network service node packet data (PDSN) acts as a stand-alone server access network (NAS)in mobile IP network, it can be run as a private agent (ON) or a foreign agent (FA). Serving a host packet data (PDSN) implements the following operations:

- Controls the interface packet radio between base transceiver subsystem (BTS), the controller base station (BSC) and the IP network by establishing, maintaining and complete the channel to the mobile client;

- Terminates the session Protocol point-to-point connection (PPP), initiated by the subscriber;

- Provides the IP address of the subscriber (or from the domestic Bank or through server dynamic host configuration Protocol configuration head machine (DHCP) or via a server authentication, authorization, and accounting (AAA));

- Performs packet routing on the external network packet data, or packet routing own agent (ON), which optionally can occur through secure tunnels;

- Collects and sends the packet data of the invoice;

- Actively monitors subscriber services based on profile information, adopted on the SCS server authentication server authorization, and accounting (AAA); and

- Authenticate users locally or queries

authentication, server authentication, authorization, and accounting (AAA).

Server authentication, authorization and accounting

Server authentication, authorization, and accounting (AAA) is used for authentication and authorization of subscribers for network access and storage of subscriber usage statistics for the invoice.

The native agent

The native agent (ON) supports the inextricable data roaming on other networks that support IxRTT. The native agent (ON) provides support IP address for mobile systems and directs any mobile traffic in the network for delivery to mobile phone. It also saves the user's registration forwards the packets to the service node packet data (PDSN) and (optional) creates a secure tunnel to the service node packet data (PDSN). Finally, the native agent (ON) supports dynamic assignment of users from the server authentication, authorization, and accounting (AAA) and (again optional) assigns dynamic of its own address.

The traditional setting of a single invocation in the access network CDMA2000

The following describes the scenario of a successful call setup for a single wireless device to establish a connection connection in the access network CDMA2000. note that this explanation bypasses the steps on the radio/radio base transceiver subsystem (BTS), concentrating instead on the functions of the Protocol, which started with the beginning of the dialogue between the wireless device (MS) and the controller base station (BSC):

1. To register for packet data services, wireless device (MS) sends the initial message over a channel of access to the base station subsystem (BSS).

2. The base station subsystem (BSS) notifies the initial messages, returning wireless device (MS) the receipt of the message.

3. The base station subsystem (BSS) creates a request message service SEE and sends this message to the mobile switching center (MSC).

4. Mobile switching center (MSC) sends a request message selection in the base station subsystem (BSS), requesting the allocation of radiorecorder. No terrestrial channels between the mobile switching center (MSC) and the base station subsystem (BSS) is not allocated call packet data.

5. The base station subsystem (BSS) and a wireless device (MS) carry out procedures for establishment of radio resource. Function package management (PCF) recognizes that no connection is available And 10 associated with this wireless device (MS), and selects the service node packet data (PDSN) for this call data. Connection And 10 is an expression defined by the texts of the standards, and refers to the interface between the controller base station (BSC) and the serving host packet data (PDSN), where And 10 represents the user IP data exchanged between the controller base station (BSC) and service node packet data (PDSN).

6. Function package management (PCF) sends a request message to the registration A11 in selected service node packet data (PDSN).

7. The registration request an acknowledged and serving node packet data (PDSN) accepts this connection, returning the response message reception A11. And service node packet data (PDSN), and the function of package management (PCF) create a linking the entry to connect And 10. The expression «EN» means a service signals are exchanged between the controller base station (BSC) and service node packet data (PDSN).

8. Once installed and radio line of communication, and connection of the a10, a base station subsystem (BSS) sends a message to complete the selection in the mobile switching center (MSC).

9. Mobile system and service node packet data (PDSN) establishes a connection channel (PPP), and then perform the procedure mobile IP registration through this connection channel (PPP).

10. After completion of mobile IP registration of a mobile system can send/receive data through crop GRE connection a10.

11. Function package management (PCF) periodically sends a request message to the registration A11 for renewal registration for connection a10.

12. For a confirmed registration request A11 service node packet data (PDSN) returns a response message reception A11. And service node packet data (PDSN), and the function of package management (PCF) updating linking record join the a10.

For a voice call switched requires additional elements shown in FIGU. In particular, this packet received from a wireless device (MS), is sent from the service node packet data (PDSN) media gateway (MGW), where it is converted to speech circuit-switched and delivered to the public switched telephone network (PTSN). In addition, the data call settings communicate with the proxy server initiated the session Protocol (SIP)to ensure that the Protocol is a utility signals and the call for communications based on IP, which can support functions and characteristics of the call, present in the public switched telephone network of General use (PTSN). The control function of the media gateway (MGCF), and gateway service signals (SGW) implement signs call, present in the signaling system 7 (SS7).

Figure 4 illustrates in the form of a block diagram of the architecture of implementing the aircraft systems IP address of a mobile Internet Protocol that provides IP addresses to mobile Internet Protocol in the above network EVDO. Circuit-switched network 401 of public data connected via radio communication lines of many hundred 421, 422 block 402 communication «air-earth» (part of the Wake interface 209 of figure 2), and then to the control processor 403 «air-earth» (part of the Wake interface 209 of figure 2). Block 402 communication «air-ground» includes many modems 411, 412 «air-ground» for the completion of the radio-frequency communication lines, supported honeycombs 421, 422. Block 402 communication «air-earth» also includes the mobile IP client 413. RF structure for modem «air-earth», as a rule, uses many modems where one modem «air-earth» (modem 411 «air-earth») is working with vertical polarization signal, and the other modem «air-earth» (modem 412 «air-earth») work with the horizontal polarization of the signal; and as the intensity of the signal is lost/accrues in a separate modems «air-earth», this modem «air-earth» goes idle or active.

Figure 5 illustrates in the form of a block diagram of the architecture to the aircraft system IP address of a mobile Internet Protocol that provides mobile IP address outside the network EVDO using mobile IP tunnel. In this second case, the implementation of the Protocol each of modems 511, 512 «air-earth» assigned IP address, and mobile IP client 513 is the host processor 503 «air-earth». Mobile IP client 513 configured with its own address 514, and the corresponding addresses mobile Internet Protocol 515, 516 associated with the modem 511 «air-earth» and modem 512 «air-earth», respectively, in unit 502 communication «air-earth». Mobile IP client 513 in the control processor 503 «air-earth» is connected via a mobile IP tunnel 514 with the public switched network 501 of public data. RF structure for modem «air-earth», as a rule, uses many modems where one modem «air-earth» (modem 511 «air-earth») is working with vertical polarization signal, and the other modem «air-earth» (modem 512 «air-earth») work with the horizontal polarization of the signal; and as the intensity of the signal is lost/accrues in a separate modems «air-earth», this modem «air-earth» goes idle or active.

This implementation uses the mobile GR client 513 in the control processor 503 «air-earth», but any extraneous agent, because transmission of addresses 515, 516 made in mobile IP client 513, which is a private address 514 and server address 519 own agent and can use the program addresses 515, 516 any modem 511 «air-earth» or modem 512 «air-earth». When a registered only mobile IP client 513, native agent has 504 mobile IP tunnel 504 to pass addresses 1 (515) in the modem 511 «air-earth» or pass addresses 2 (516) in the modem 512 «air-earth». Mobile IP client 513 in the control processor 502 requests information from a block 502 communications air-ground update mobile IP bindings to the server 519 own agent. Mobile IP client 513 must accept IP addresses assigned by the modem 511 «air-earth» and modem 512 «air-earth» (this is the address transfer for mobile IP client). Mobile IP client 513 must have configured/known own address 514 and server address 519 own agent. There is mobile IP tunnel 504 on the modem 511, 512 «air-earth» or mobile IP tunnel 504 on the client WiFi.

6 illustrates a typical addressing used in the system by figure 5, and 7 illustrates the transfer of IP tunnel between modems «air-ground» with the resulting change in the typical addressing, which is shown in Fig.6. On these drawings are streams of data to the public switched network 501 of public data, which consist of payload data and added to the beginning address of the destination DIP=NAA and DIP=NEW When these data streams transferred in tunnels A and 514 MIP, in the beginning of threads are added to the data address consisting of addresses for sending SOA and SOA, respectively, and total encapsulation routing (ORE). Admission to the host processor 503 «air-earth» new address headers these data streams are erased and restored to its original addressing. 7 one tunnel MIP is routed via modem 511 «air-earth», thus the resulting addressing change at the beginning of addresses used in this tunnel MIP, with the DIP=CoA.2 on DIP=CoA.1 for this thread.

Fig illustrates in the form of a block diagram of the architecture to the aircraft system IP address of a mobile Internet Protocol that provides IP addresses to mobile Internet Protocol offline EVDO with the help of IP tunnels. In this third variant of implementation of the Protocol each of modems 811, 812 «air-earth» is assigned an IP address, and simple IP addresses are controlled in block 802 communication «air-earth». Many of IP tunnels 805, 806 connect the control processor 803 «the air-ground router 804 in terrestrial network access. Control processor 803 «air-earth» functions as the destination of tunnels and use a public address 813 for these IP tunnels 805, 806. Traffic switches between modems 811, 812 «air-earth» as the intensity of the signal is lost/accrues in a separate modems 811, 812 «air-earth».

Fig is an example of providing the IP address of a mobile Internet Protocol outside the network EVDO. Both modems 811, 812 «air-ground» are modems traffic, and both are connected and try to establish sessions/connections. Each modem 811, 812 «air-earth» has assigned to him a simple IP address which can be routed in aircraft network. As in the above systems, radio frequency structure for modem «air-earth», as a rule, uses many modems where one modem «air-earth» (modem 811 «air-earth») is working with vertical polarization signal, and the other modem «air-earth» (modem 812 «air-earth») work with the horizontal polarization of the signal; and as the intensity of the signal is lost/accrues in a separate modems «air-earth», this modem «air-earth» becomes inactive or active.

Control processor 802 «air-earth» functions as the destination of the tunnels, as defined in the documents of industry standards, and requires that a public address 813 destination of the tunnels was made in the control processor 803 «air-earth». Control processor 803 «air-ground» can tunnel data modem 811 «air-earth» and (or) modem 812 «air-ground» on the basis of operational performance of the modem «air-earth» (SINR, pie download, etc). In terrestrial end of this line 804 router performs functions destination 808 tunnels. Alternatively, the server 808 can be implemented in the core network for figa and 3B, in order to implement functions destination tunnels.

The server 808 is in the core network, and the client 807 is the host processor 803 «air-earth». IP data transmitted via this link, look indistinguishable from the application content from IP data is not transmitted via this link. The client 807 handles packets immediately before the transfer, and is the first in packet processing after the reception, so tunneling Protocol transparent to the software of a higher level. So, client IP address WiFi saved after passing through the tunnel and is transparent to multiple IP tunneling. Every fragmentation and reassembly of data is easy because TCP sessions are completed at the customer 807 and server 808. through the tunnel are only data, and the boundaries of the packages used in packets through the tunnel, have no connection with the original packaging TCP/IP. So fragmentation TCP/IP between the client and WiFi client 807 completely isolated from the TCP/IP connection between the server 808 and a source server, and oboroten can be segmented between the server 808 and a source server, and this fragmentation does not affect the TCP connection between the client 807 and WiFi client.
