Abstract

End point device interacts directly and/or indirectly both with a first node using a first protocol and a second node using a second protocol. In one embodiment, the first node and the second node are access points. The second node does not have first node network address even if it is communicatively coupled to the first node via an alternate upstream path. The first node does not know second node network address. The end point device has the first node network address and the second node network address. The second node sends data destined for the first node to the downstream end point device. The end point device applied necessary coding, formatting and/or encryption to the data before delivering the data to the first node using the first node network address if the first protocol is different from the second protocol. Else the end point device forwards the data to the first node. The end point device in addition acts as a bridge for data from the first to the second node. Each of the first protocol and the second protocol is circuit switched or packet switched data communication protocol.

Through the following specific implementation mode The advantages of the present invention will become more apparent in conjunction with the related drawings. [Embodiment] FIG. 1 is a perspective terminal between a plurality of access networks (1) and $117 connected to a terminal device according to the present invention. A schematic diagram of the data exchange process performed by device 131 EPD (terminal Han) 131 may be, for example but not limited to, a notebook, a personal computer, a private computer, a server, a PDA (Personal Digital Assistant), and a video game machine. Each of 111 113, 115, and 117 is circuit-switched data, network or packet-switched data, 罔. Multiple access networks 111, 113, 115, and 117 can operate in accordance with the same protocol. Another implementation of the present invention In the case, multiple access networks ηι Each of 113, 115, and 117 is 10, and the number of access networks (1), m, m, and 117 may be one or more service providers. For management. Typical examples of multiple access networks m, n3, m, and 117 are job network or other MN (wireless area network), wlan, satellite network, cable power _, fiber network, (10) network, qing s Network 'CDMA network' EDGE network, WCDMA twist. In this thin hour hand, as shown in Figure!, the first access network m through the invalid communication link (in〇p touch vec 咖丽at face

The toe) communication is connected to the backbone network 103. The second access network 113 and the third access network n5 are communicatively coupled to the backbone network 103 via respective active communication links (operative 〇 cunmmunicaii〇nlink). The fourth access network 117 is not communicatively coupled to the backbone network ι. The EPD 131 is communicatively coupled to each of the multiple access networks (1), (1), and 117 via a communication link. The communication link between the EPD 131 and any of the multiple access networks, ιΐ3, outgoing and claws may be a wired link, a wireless link, or a tree and wireless hybrid link. The EPD 131 includes a first access network I/F (interface) 145, a second access network from m, and third and fourth access network I/Fs 149. These interfaces 145, (4) and 149 are one or more of a body and a weight. The EPD 131 transmits the first access network I/F 145, the second access network I/F H7, and the third and fourth access networks ρ/ρ 149 to the first access network m and the second access network, respectively: The third access network 115 communicates with the fourth access network 117. The coffee maker 3i further includes a data transfer circuit 141 and a bridge circuit 143. Optionally, one of the data forwarding circuit m and the bridging packet 143 may be turned off, or both may be turned off at the same time. Each of the accesses, . . . , 111, 113, 115, and 117 includes a plurality of intermediate routing selection nodes. The intermediate routing node is typically a client Ap (access point), (service provider) AP, router, switch, hub, and the like. For example, but not limited to, the first IRN (intermediate routing node) belonging to the 11 200836521 - access network 111 generates data destined for the second leg belonging to the second access network 113. The data may be a command, a control message, a path message (such as delay, traffic congestion, supported bit rate, interference, protocol parameter setting, etc.) issued by the second IRN, a handover request sent to the second party, a traffic sharing request, etc. . The first-IR transmits the generated data through the EPD 131 instead of through the backbone network 1〇3. # For example, the first IRN cannot communicate with the second side through the backbone network 1〇3 because the communication link between the younger-access network 111 and the backbone network 1〇3 is invalid. The first brain will send the data to the station 131 for the second Cong. The first leg may not be directly connected to the deletion. For example, the first _ is connected to the d(3) through the first-Ap connection. In this case, the first -_ encapsulates the coffee network address and the second hard identifier in the data, and then sends it to the -AP. The first place then forwards the received data to (4) EPD 131 receives the data through the first access point I/p 145. Bp. 131 uses the second IRN identifier to determine that the data is sent to the second job. In the embodiment, the same data communication protocol is used to communicate with the first access, the port 111, and the first access network 113. In this case, the data forwarding circuit T of the qing (3) forwards the received data to the second access network 113 through the second access network I/F 147; [the RN can be indirectly connected to the second AP through the second In this case, the second access network I/F 147 of the coffee m forwards the received data to the second place, and the second AP sends the data to the second side. In this way, the data initiated by the first leg in the first access network (1) passes through the second leg in the second access network 113 of the service provider. In another embodiment, the EPD 131 communicates with the first access network m using the first protocol, and the second protocol that is not compatible with the first protocol on the overnight communication with the second access network 113 12 200836521 Letter. For example, the first access network m is a wlAN network, the first protocol is a dirty δ〇2 ιι protocol, and the second access network 113 is a WAN (wireless area network), using a dirty 216 protocol. In this case, the bridge circuit 143 of the EPD m will process the _ of the _, to generate processed data in accordance with the second protocol. This process typically involves decoding/encoding, deformatting/formatting operations. (d) 131 sends the processed data to the second leg through the second accessor I/F w. In this way, the data initiated by the first job in the first access network m passes through the EPD 131 to reach the second random access in the second access network 113.

The second one of the second access networks 113 generates second data for the third IRN in the third access network 115. The second access network 113 and the third access network ι 5 are communicably connected to each other through the backbone network (10). The third leg does not know the network address of the third brain. Second, the second data that arrives at the station as the third difficulty is sent to EpD m. The coffee i3i receives the second data from the second job through the second access network i/fm, and then sends the third data to the third _ through the third and fourth access network sands, and may It is necessary to deal with the type of protocol used by the second access network 113 and the third access network 115, and the epd ηι stores the network address of the third job in its memory. Qing (3) sends the final package data to the second and fourth access network I/F 149 after being encapsulated into the third IRN network bit 2 through the second data packet of the first access network I/F 147_ Three legs. The third IRN may be connected to the EpD i3i through the third place. In this case, the file is stored as a third-party network address. The EPD 131 encapsulates the network address ' at the second data in the second data' and then transmits it through the third and fourth access network I/F 149. The second data sealed by the third word is forwarded to the third IRN. The first access network 221 and the second access network 241 and the backbone network 203 are connected to each other through the backbone network 3 and through the downstream terminal device 271. A schematic diagram of a data exchange process between any two nodes through the downlink terminal device 271. The first access network 221 includes a first set of intermediate routing nodes (IRNs) 231, 233, 235, 237, and 239. The first set of intermediate routing nodes (IRNs) 231,

233, 235, 237, and 239 are connected directly and/or indirectly to each other. The first set of intermediate routing transport points (IRN) 231, 233, 235, 237, and 239 may be the first SP-AP

(Service Provider Access Point) such as 239, routers, switches, etc. The second access network j includes a second group 1 cis 251, 253, 255, 257, 259, and 261. The second group 11^251, 253, 255, 257, 259 and 261 are connected directly and/or indirectly to each other. IRN 261 is the second SP-AP. The backbone network 203 includes a third group of IRNs 211, 213, 215, 217, and 219. The third set of IRNs 21, 213, 217, 217 and 219 are connected directly and/or indirectly to each other. The EPD (Terminal Device) 271 is communicably connected to the second SP-AP 261 via the first communication interface (Ι/ρ) 277 to the first SP-AP 239' via the second communication interface 279. Therefore, EPD271 can pass the first communication! ^277 communicates with any of the first set of IRNs and the first SP-AP 239, and communicates with any of the second set of IRNs and the second certificate 261 via the second communication I/F 279. After associating itself to the first SP-AP 239 (i.e., the first access network 221), the EPD 271 receives the first network address from the -SP-AP 239. The first network address of EpD 271 will be passed to all IRNs in the first set of IRNs (dEPD 271 and/or first _AP 239 may choose to send the first scale location of EPD 271 to the third set of legs All of the marrow, or at least some of the legs. Similarly, after associating itself to the first (ie, the second access network 241), the EPD 271 receives the second network 14 from the second sp_Ap261. The second petal 1 of the New ° EPD271 will be transmitted to all the ceremonies of the second group of brains, and will be selectively transmitted to all brains in the third group of brains, or at least one of them, facets. Both the leg and the second leg can send data to the EpD 271. Any -IRN in the first set of faces does not know any of the second set of Cong's network addresses, and vice versa. The memory of the EPD271 is stored in Corresponding to the first network address of the first sp_AP 239 and the second sp_Ap and the network address corresponding to the second SP_AP 261. The π π uses the first SP-AP network address and the second sp_Ap network address respectively to the first 10239 and the first SP-AP 261 send data. ^ If not limited to, the first group of the brain - 233 ± into the second group of Lizhong second brain 253 The data may generally be a request, a command, a control message, a path message, etc. The first access network 221 and the second access network 241 are respectively served by two different service providers. The first access network 221 The same protocol is used in the data communication process with the second access network 241. The first side 233 does not know that the network address of the second leg 253 is encapsulating the person 271 in the data of the second brain 253 at the destination end. The first network 10 address is then sent to the EPD 271. After passing through the first sp_Ap 239, the data arrives at the first communication I/F 277 of the EPD 271. The EPD 271 is received through the first communication ι/ρ π The data is encapsulated into the network address of the third SP-AP, and then forwarded to the second SP_AP26 through the second communication Ι/ρ 279. Second, the data is forwarded to the second IRN 253. Thus The data generated by irn233 reaches the arrival station end IRN through the EpD27i, that is, the second IRN 253. In another embodiment, the first access network 221 uses the first protocol for data communication, and the second access network 241 uses communication. The second protocol that is not compatible with the first protocol carries the number 15 200 The first IRN 233 sends the data to the EpD 271. The EpD 271 passes the SP-AP 239 and the first. After the data of the first: IRN2S3 is encapsulated into another first network address, the first IRN 233 sends the data to the EpD 271. The communication I/p 277 receives the training. The built-in bridge of the EpD η and the private path 275 process the received data to conform to the second protocol. This process r typically includes decoding, arranging, formatting, and the like. The EPD 271 sends the processed data conforming to the second protocol to the second sp_Ap 261 via the second communication ι/ρ279. Second, the second processing data is forwarded to the second 253. The first protocol may be, for example, a fiber optic data communication protocol, and the second protocol may be, for example, a wireless LAN 35 protocol such as ΙΕΕΕ8〇2 ιι. The king face in the second set of legs generates a second number of passes to the second leg 253. The third brain 211 does not know the network address of the second listener 253, and encapsulates the first network address of the EPD 271 in the second data, and then sends it to the first access network 221. For example, but not limited to, the fourth leg 235 of the first group is used as a communication gate for the first access network 221. The fourth 1 belly 235 receives the encapsulated second data from the third IRN 2u. The second data is sent to the first sp_Ap239, which sends it to 271. Which 271 sends the second data to the second sp_Ap26i through the second communication I/F 279, and may need to send the second data to the built-in bridge circuit 3 for processing, which is required to be processed with the first access, the network 221 and The type of protocol used by the second access network 241 is related. The second sp-site 261 forwards the second data to the arrival station, that is, the second smart. 3 is a schematic diagram of the terminal device supporting the data exchange between the first access point and the second access point milk through the terminal device 351 according to the present invention, wherein the first access point 313 and the second connection The in point 323 can be connected to each other through the upstream backbone network and through the downstream terminal device 351. The EpD 351 is communicably connected to the upstream first (access point) 313 through the first communication interface (10) 16 200836521 355, and communicates with the upstream second AP 323 via the second communication I/F 363. The first-AP 313 communication connects the downstream stream .351 and the upstream first node (not shown) belonging to the first access network 311. The first access network 通信1 is communicatively coupled to the upstream backbone network 3〇3, that is, the first AP 313 can interact with the upstream backbone network 303. Similarly, the first: 323 can interact with the downstream EpD 35l and interact with the upstream backbone 3 〇 3 via an upstream second node (not shown). The first 323 323 uses the first protocol 361 to handle upstream and downstream data communications. The second A? milk uses a second protocol 369 that is not communicatively compatible with the first protocol 361 to handle upstream and downstream data communications. For example, the first protocol 361 is the ffiEE 8〇216 protocol, and the second protocol 369 is the wired data communication protocol. After associating itself to the first AP 313 for the first time, the EPD 351 receives the young AP address 357 and the first EPD address 359 from the first ap 313. The first AP address 357 can uniquely identify the first AP 313. The first AP 313 uses the first EPD address 359 to transmit data to the EPD 351. After being associated with the second AP 323, the EPD 351 includes the built-in AP bridge circuit 353 from the second AP 323 to the second AP address 365 and the second EPD address 367 〇 EPD 351. The first access network 311 and the second access network 321 are each maintained by two different service providers. The first AP 313 does not know the address 365 of the second AP, and the second AP 323 does not know the address 357 of the first AP. The EPD 351 interacts with the first AP 313 via a wireless link and interacts with the second AP 323 via a wired link. The first AP 313 wants to send data to the second AP 323. The data generally includes a handover request sent to the second AP 323, a traffic sharing request sent to the second AP 323, a path message of the communication path between the backbone network 3〇3 and the first Ap313, and a delay in the second access network 321 And/or traffic congestion status query message 17 200836521 and so on. I don't know the first: ΛΡ address 3 (4) - axis 3 sends the data to delete. The 35i receives the data through the first communication I/F 355. The built-in 桥ρ bridge circuit in the coffee 351 formats and/or encodes the data to generate processed data. The processed data conforms to the second protocol. The sub-51 transmits the processed data to the second Le 3 through the second communication ι/ρ and using the second Ap address milk. When the second milk 23 wants to send the second data to the first AP 313, it sends the second data to the 351 using the second protocol and the second address 367. The EPD 351 receives the second data through the second communication purchase 63. The built-in λρ bridge circuit 3S3 in the 51 deletes and formats the second data to generate second processed data conforming to the first protocol 361. The 351 sends the first AP data to the first AP 313 via the first communication (10) 355 using the first AP address 357 _.仏&AP313 and AP323 communicate with each other via the upstream backbone network 3〇3 but the data exchange between the two still needs to be carried out through the downstream, because the first AP 313 and the The two Ap 323 do not know each other's network address. In another example, although the first AP 313 and the second location 323 obtain the other party's network address ', they are not connected to each other through the upstream backbone network 3〇3. In this embodiment, the 'AP-AP 313 and the second milk 23 exchange data between each other through the downstream Ερ〇25ι. When the data flows through the EPD sister, it is necessary to properly handle the data originating from one of the two parties (the -APM3 and the second location 323) and the other party to the other party Ap. A bridging operation is performed between the AP 313 and the second AP 323. 4 is a schematic diagram of an example of a terminal device supporting data exchange between a first intermediate routing node 411 and a second intermediate routing domain 4S1 in accordance with the present invention, wherein the 18th 200836521 - intermediate routing node 411 and the second intermediate route The selection node 451 is connected to the terminal device 491 through the first access point 431 and the second access point 471, respectively. The first intermediate route, the selection node (brain) 411 still communicates with the first data network 481 through its upstream communication interface (i/f), and also communicates through the downstream communication Ι/ρ421 with the first ^ (access point) ) 々η interaction. The first IRN 411 communicates with the first location 4" using the first Ap address 415. The first AP 431 communicates (interacts) with the first IRN through its upstream communication ι/ρ 433, through its downstream communication I/F 439 and EPD (terminal device) 491. The first AP 431 communicates with the brother 411 using the address ^ 435. The first AP 431 interacts with the EPD 491 using the first EPD address 437. The first irn 411 is in its memory The first epd address 437 is stored. Therefore, before the data sent to the EPD 491 is sent to the first Ap431, the first IRN 411 encapsulates the first EPD address 437 in the data. The second IRN 451 is upstream through it. The communication ι/ρ 453 interacts with the second data network 485, interacting with the second AP 471 through its downstream communication I/F 461. The second IRN 451 communicates with the second AP 471 using the second AP address 455. The second AP 471 communicates with the second coffee 451 through its upstream communication _ I/F 473, and communicates with £0 491 through its downstream 1/?479. The second AP 471 uses the second IRN address 475 and the second IRN 451. Communication, the address uniquely identifies the second IRN 451. The second AP 471 interacts with the EPD 491 using the second EPD address 477. The second IRN 451 is stored in it The second EPD address 477 is stored in the memory. Therefore, before the data sent to the EPD 491 is sent to the second AP 471, the second IRN 451 encapsulates the second EPD address 477 in the data. The first AP431 And the first IRN 411 is part of the first data network 483. The second AP 471 and the second IRN 451 are part of the second data network 485. The first AP 431 and the first IRN 411 operate in accordance with the first protocol. The second AP 471 19 200836521 and the The second IRN 451 operates in accordance with the second protocol. The first protocol and the second protocol are mutually compatible or non-compatible with each other. The first IRN 411 generates data to be sent to the second IRN 451. The first IRN 411 does not communicate through its upstream communication I/ F 413 sends the data to the path of the second IRN. Even if such a communication path exists, the first IRN 411 does not know the second IRN address 475. The first IRN 411 adds the first AP address 415 to the second IRN identifier in the data, The arriving station end indicating the data is the second IRN 451. The data added by the first IRN 411 through its downstream communication I/F 421w is sent to the first AP 431. The first AP 431 forwards the data to the EPD 491 using the first EPD address 437. EPD491 from The arrival station of the data is determined in the second IRN identifier: ^ is the IRN 451. If the first AP 431 and the second AP 471 use the same communication protocol, then the data does not need to be formatted and/or encoded. The data forwarding circuit 493 of the EpD 491 adds a second Ap address 455 to the data. If the first Ap 431 and the first Λρ 471 use different communication protocols, then the data needs to be formatted and/or encoded to conform to the protocol used by the second 471. In this case, the built-in AP bridge circuit 495 of the EpD 491 performs formatting and/or encoding operations to conform to the protocol used by the second AP 471. The built-in bridge circuit peach also adds the first AP address 455 to the formatted data. The second communication I/F 499 of the EPD 491 transmits the data obtained from the data forwarding circuit 3 or the built-in Ap bridge circuit 5 to the second. The first AP 471 then forwards the data to the second brain 751 through its upstream communication I/p 473 and using the second address 4. When the data is transmitted from the initiating end, i.e., the first brain to the second station 451, the second brain 451, 卿ρ〇49ΐ performs the necessary formatting and/or encoding processing on the data. The first leg river and the first leg are collected as one of 20 200836521 or more routers, access points, switches, and so on. The first brain 4n may be a service provider access point, and the first AP may be a client access point. The foot 491 can be a second computer, a PDA, a laptop, a telephone, a video game box, and the like. The data communication protocol used by the first and second APWs may be either a circuit switched protocol or a "group exchange protocol" or a combination thereof. ' σ > The first leg 451 generates the second data sent to the first Cong 4U. The second deletion does not know the first leg address 435, then sends the second data to the office. In the process of transmission via the ^1, EPD 491, and the -AP 431, the second data finds a path to the -IRN 411.

The first access point 513 is the service provider. Point (SP_AP), which is part of the hunger net crime. The -SP-APM3 uses the first knowledge 56^ (usually the positive 8 〇 2 · ii) to come with the coffee 541 and the peeling net 5n W ^... he is The packet exchange data communication is performed at the point (not shown). The first SP-AP 513 is connected to the coffee 541 through the first communication. The first communication Ι/ρ is operated by the first protocol 561. 筮 ― 分 t ..., The first access point 533 疋 service provider access point (sp_Ap), which is the WAN network 531 - such as eight # 邛 knife. The second two SP-AP 533 uses the second protocol 569 (usually IEEE 802.16 co-site &&&) to perform packet-switched data communication with any other node 21 200836521 (not shown) in the EPD 541 and the WAN network 531. The second SP-AP 533 transmits the second communication I/F 563 and the EPD 5 41. The second communication I/F 563 thus operates in accordance with the second protocol 569. The network 511 and the WA1S [network 531 ', that is, the brother-SP-AP 513 and the second SP_AP 533 are connected to each other via the upstream backbone network 503. The first SP-AP 513 does not know the second AP address 565 for the only two-in-one gp_AP 533. The second SP-AP 533 also does not know the first AP for uniquely identifying the first SP-AP 513. Address 557.

The EPD 541 includes a built-in AP bridge circuit 543. The second sp-Ap knows that it wants to transmit packet data to the first SP-AP 513. The packet data typically includes a first handover request, a current performance message for the WAN network 531, a traffic load distribution request, a query message for the current performance of the WLAN network 511, control commands, and the like. The second sp_Ap magic channel 503 is indirectly connected to the first SP_AP 513 via the upstream backbone network 503. The second _ _ 533 cannot send data to the first accomplice through the upstream backbone network 5 〇 3 because the second SP-AP 533 does not know the first Λ ρ address 557. The second offender 533 uses the first coffee address 535 and the first -SP_AP identifier to report to the chat 541 Wei. The number of age groups is encoded by the second place-by-part before being transmitted according to the second packet exchange data protocol 569. The deletion 41 receives the packet data through the second communication (4) 3. The built-in circuit 543 decapsulates the packet data and transmits it to the first SP_AP 513 by using the first commit packet data. The built-in (6) 仃X see green n-set A^ bridge circuit 543 formats and/or encodes the packet data in accordance with the first packet switched data protocol 561. The first (fourth) measurement first-AP address 557 sends the formatted packet data to the first (10)^513. In this way, the packet data arrives at the first SP_AP 513. Similarly, the first scam 3 sends the second 22 200836521 packet data to the second place 33 through the EPD 541. EPD 54! is used as a bridge between the first spi 513 and the second sp_Ap, connected to the device. Since the first-SP_AP 513 and the second-practice 533 use two mutually incompatible, packet-switched data protocols', the EPD 541 decapsulates the packet data received through the first communication (4) 5 and the second communication 563 ', Encapsulating, decoding/encoding and/or decrypting/encrypting, and then transmitting the packet data through the other of the first communication I/F 555 and the second communication ι/ρ. 6 is a plurality of components included in a terminal device that supports a data stream between two uplink access points in accordance with the present day.

The first protocol 643, the second protocol 653, the third protocol 4 663, and the fourth protocol 673 may be one or more of a circuit switched data protocol and a packet switched data protocol. The first Ap, the second, the third, and the fourth Ap do not have each other's network address. The first AP, the second Ap, the third Ap, and the fourth are served by the same or different service providers. The EPD 600 can typically be a server, video game console, personal computer, notebook, PDA, telephone, and the like. The EPD 600 includes a display 603 and a user interface (I/F) 61. The user I/F 611 is, for example but not limited to, a mouse, a keyboard, a touch pad, a handwriting interface, a voice interface, 23 200836521 touch screen, and the like. The EPD 600 includes a storage system 6〇5 in which an Ap address 6〇9 and a pull 1 network address 607 are stored. Each of the first AP, the second AP, the third AP, and the fourth AP is uniquely identified by a network address, and the Ap address 6〇9 refers to four unique network and road addresses corresponding to four APs. . The EpD 6〇〇 associated with the four APs of the Ting can transmit and receive data with the four Aps. Each of these four APs distributes a unique network address for EpD 6 (8), and these four locations use the EPD network address 6〇7 to identify the EPD 600.

The EPD 600 includes an AP data forwarding circuit 621. EpD 6(8) also includes built-in; private channel 631, which includes some sub-modules, such as encoding/decoding module, sealing/de-packing module 635, and the like.

FIG. 7 is a schematic diagram of the multi-parts included in the middle routing node in accordance with the local-transmission terminal device and the other intermediate-domain selection node. The brain (intermediate routing node) 700 is, for example but not limited to, a service provider access point, a client access point, a router, and the like. The job is part of the access network and/or is part of a backbone network that connects two or more access networks. There are two upstream interface states and 75 and two downstream communication interfaces 761 and 771. _ is associated with the first upstream IRN 743 through the first upstream f (interface) 741. _ is also associated with the first upper 仃 ilI / F75 卜 - downstream and the second downstream through 77i and the first hunger IRN751 f downstream 633 and the second downstream node (7). The first-downstream node 763 and the second downstream node 773 are usually terminal devices, terminals, routers, and the like. EPD (terminal equipment) is a telephone, a notebook computer, a personal computer, a PDA, a ship, a video game machine, and the like. For example, but not limited to, the brain is a service provider access point, the first-downstream node 763 is a client access point, and the second downstream stream 25 200836521 node 773 is a laptop. The first upstream stream 743 is a router, and the second upstream stream IRN 753 is a switch. The IRN 7 (8) associated with the upstream IRNs 743, 753 and the downstream nodes 763, 773 in communication stores the network address 715 of these upstream IRNs in their storage system 711 and the network addresses 713σΙΚΝ7 of these downstream nodes. The first protocol is used to communicate with the upstream IRNs 743, 753 and the downstream nodes 763, 773. The IRN 7 generates data for the second (not shown). Ihun 700 does not know the network address of the second I. I(10)7〇〇 The EpD address 721 is stored in its storage system 711. 1}^7(8) knows that EpD stores the network address of the second IRN. The processing circuit 723 in the IRN 7 that does not know the second IRN (not shown) network address transmits data to the EPD through the EPD address 721 through one of the paging interfaces 761 and 771. The EPD receives data from the leg 7 (8) directly or indirectly. If the clerk is the first lower stream node 673 or the second downstream node 773, the EpD will receive the data directly from the face 7 (8). On the other hand, if the coffee communication is connected to one or more of the downstream node 673 and the claw, the EPD indirectly deletes and receives the data. When necessary, the EPD processes the data received from the brain 7 , and then uses the second view (the unillustrated _ road address will be the number _ to the second (four). If the leg 7_π second is separately If the protocol is working on a mutually incompatible protocol, then the data is processed before the data is sent to the second. If the _ and the second leg use the same protocol for Ruitong k, the EPD directly forwards the data. The second leg, (iv) the opposite line processing. The IRN 7 (8) can also serve as the arrival station end of the data generated by the second node (not shown). The 仃 攸 仃 leg 743 receives the second data. The processing circuit of the brain 7 (8) is determined 】 26 200836521 end address. If the second data is sent to the down call _, then the toilet over the brother - downstream about 61 will send the second data to the first - downstream section. In the face, it is difficult to use The relationship between the data originating end and the arriving station end is connected to the second embarrassment through the ascending rider. I do not know that the second brain network address is added to the claw through the downstream communication interface. Among them - use the coffee address cut to send data to the second job. Figure 8 is in accordance with the present invention The terminal set up the bridge to the middle-middle way. The typical example of the middle route selection is the PC, laptop, PDA, video game console, telephone, servo and so on. The coffee bean includes a first wireless circuit and a second wireless circuit.

If it is difficult, the face is directly connected to the EPD. In the step 8n, the EPD receives data from the first leg through its first wireless circuit and the -AP. The well-being is initiated in the first brain, and is sent to the first by the first irn. In the step, the first AP forwards the data to the clerk through its first wireless circuit. Which and the AP interact with each other using the first protocol. The first wireless circuit is used to process the data using the first protocol. Communication. If the first job is the first place, the first one is the originator of the data. In the next step 821, the EPD is the same as, for example, (4) confirming the Zhao __ end address. If the 27 200836521 data is To the EPD, the financial step 83 EpD reads the new data. New, Ep[) waits from the first -IRN Data. If the data is sent to the third job, the EPD determines the protocol used by the second AP for data communication at step 841'. The coffee is ready to send the data to the second I belly through the second AP. If the AP: uses the first protocol for data communication, the EpD adds the network address of the second AP to the data received through the first wireless circuit. Next, in step (6), the EPD sends the data to the second place through the second wireless circuit. The second place forwards the data 2 second. Then, the coffee waits for the next data from the first brain. In this scheme, the second wireless circuit uses the first protocol to process the data communication. If the second I uses the second protocol for data communication, then in the step, the coffee processes the data to conform to the second protocol. Usually includes encoding and / or decoding, encapsulation and / or decapsulation, etc. ^ Next - step 871, EPD if the second wireless circuit sends the processed data to the second place. Second = send the processing data to the first Second _. The second scale Wei in this case according to the brother-Xiehong. Silk, coffee waiting from the first - listening to the next - from the source (also known as - the 亀 is the first: face) on the path of EPD data Perform the necessary processing.
