The invention relates to methods and devices for the treatment of advanced proxy information while the device is based on nodes and/or proxy network gateways of a wireless mesh network.

In recent years, was developed by the IEEE 802.11 s (IEEE - Institute of electrical and electronics), which specifies the use of a mesh topology with nodes/network stations in a mesh network acting as a relay for messages. To connect this wire mesh to an external station, located outside the mesh network, on the border of the mesh are implemented proxy gateway, which forwards messages from outside to inside wire mesh and Vice versa. The proxy gateway may change the content of the message, for example to convert addresses or Protocol conversion.

The Project D11.0 802.11 s IEEE defines for cellular networks WLAN - wireless LAN) proxy information and the so-called elements of the proxy update PXU and confirm the proxy update PXUC. Proxy information consists of the proxy MAC address of the proxy gateway and the external MAC address of the external station in conjunction with the optional lifetime of this proxy information. Using the elements of a proxy update PXU and confirm the proxy update PXUC �Roxy information becomes available to other nodes in a mesh network, in the result, the other nodes are informed about what external addresses can be achieved through a (proxy) gateway.

Proxy gateway G1, which represents the external MAC address of E1 may send the proxy update. However, some other network station M1 in a wireless mesh network may also send this proxy information about the external MAC address of the external station and the proxy MAC address of the proxy network gateway G1, see Fig. 1. The dotted lines indicate a communication connection, such as network WLAN communication channels.

However, network station M1 may not receive the proxy update proxy network gateway G1, which changed proxy proxy information network gateway G1 and the external MAC address of E1 (e.g., the removal of proxy information), so that the network station can send the proxy update proxy with legacy information on proxy network gateway G1 and the external MAC address E1. The recipient of both elements proxy update does not recognize the wrong chronological order, and to recover the proxy information that is incorrect.

In the current draft specification of the proxy update defines a field called PXU sequence number (8 bits). But it is used only as an identifier proxy update, which�first identifies the adopted proxy update element in the confirm proxy information (PXUC), sent to confirm the reception of the proxy update.

The message Protocol HWMP path selection (HWMP - Protocol hybrid wireless mesh network) standard IEEE 802.11 s, may also contain proxy information. It always includes the HWMP sequence number, but the sequence number is only used as a sequence number to send information, not for proxy information.

Therefore, the aim of the invention is to provide methods and apparatus that prevent the wrong setting proxy information in a mesh network.

This task is solved by the independent claims. Concrete solutions of the invention are solved dependent claims.

The invention relates to a method for forming an extended proxy information in a mesh network,

- wire mesh with nodes that are generated as a proxy gateway and/or network station,

- for external alarm MAC address of the external station located outside the mesh network, using the proxy MAC address of the proxy network gateway (G1),

- for specific pairs of the MAC address, the designated proxy address and the external MAC address,

containing:

- detect changes in the external connection the station to the proxy network gateway;

- the formation, if the detected change, order�tion number proxy information either (i) by the increment of the existing sequence number proxy information for a specific pair of MAC addresses to at least one, or (ii) using the sequence number of the message or item, encoded using the standard Protocol hybrid wireless mesh network, and this sequence number greater than the sequence number of the previously generated messages or element, encoded using the standard Protocol hybrid wireless mesh network;

- the formation of an extended proxy information through:

- first field (F1) indicating the addition or removal of compounds, the presence of a third field (F3) and the presence of the fifth field (F5);

- the second field (F2), which includes external MAC address (EMACA);

- the third field (F3), which includes the proxy MAC address (PMACA), and the presence of a third field (F3) indicates the first field (F1);

- the fourth field (F4), which includes the sequence number of the proxy information (PISN);

- the fifth field (F5), which includes the lifetime of the proxy information (PILIFE), and the presence of the fifth field (F5) specifies the first field (F1).

In the context of the present description, the term "proxy information", as known from IEEE standard 802.11 s, is called the proxy information. In addition, the enhanced proxy information is called an advanced proxy information. The term "MAC" is used as abbreviation description control access to the medium, as indicated, for example, I�p, in IEEE 802.3-2002 section 4.1.4, for example, for use in the Ethernet Protocol as the MAC address.

The advantage of this method is that you can avoid misinterpretations of messages that includes a legacy proxy information. This means that the reliability of the element proxy of information available at the nodes in a mesh network, may be increased, so as to prevent the forwarding of frames to the wrong proxy gateway due to outdated proxy information.

Serial number proxy information is increased by one for the formation of a PXU element (PXU proxy update) with proxy information, for example, for IEEE 802.11 s, especially when the lifetime of the proxy information. Another case, which leads to the increment of the sequence number proxy information relates to PXU, which is associated with the proxy information that should be removed through corresponding mesh nodes. If the sequence number of the proxy information defined for a specific pair of MAC addresses for the first time, the sequence number of the proxy information can be set to a predefined or arbitrary number.

If you use a dedicated fourth field in the advanced proxy information sequence number proxy information is formed by the increment creatures�existing sequence number proxy information. In the case if you use the sequence number of the message item standard Protocol hybrid wireless mesh HWMP, no dedicated fourth field is not formed in the extended proxy information, but the sequence number is used as a sequence number for the proxy information. Also in this case, when emitted, the new element or message, encoded by HWMP, the sequence number of the new item or message is increased compared to a sequence number previously sent HWMP element or message. This means that advanced proxy information can be distinguished from previously formed the advanced elements of the proxy information due to the higher sequence number proxy information.

The present invention also relates to a method of receiving and executing advanced information proxy information in a mesh network,

- wire mesh with nodes that are generated as a proxy gateway and/or network station,

- for external alarm MAC address of the external station located outside the mesh network, using the proxy MAC address of the proxy network gateway (G1),

- for a specific pair of MAC addresses, a specific proxy address and the external MAC address,

containing:

reception advanced proxy information;

the performance of adding and�and removal of the external connection the station to the proxy network gateway, specified advanced proxy information through the node if the sequence number of the proxy information of the enlarged element proxies more information than the existing sequence number proxy information specific pair of MAC addresses.

The advantage of this method is that you can avoid misinterpretations of messages that includes a legacy proxy information. This means that the reliability of the element proxy of information available to nodes in a mesh network, may be increased, so as to prevent the forwarding of frames to incorrect proxy network gateways due to outdated proxy information. In accordance with the previous description of the sequence number of the proxy information is extracted either from the fourth field of the element proxy of information or a sequence number of the message or item, encoded through standard HWMP. Serial number proxy information, which was adopted by the previous item or the previous message, coded by HWMP or as the fourth field of the previous element proxy information is set and used as the existing sequence number proxy information.

In an optional enhancement of the described method is advantageous to send or receive advanced proxy information as part of the elements�and or messages coded using the standard Protocol hybrid wireless mesh network. When using the standard Protocol hybrid wireless mesh network can be provided cost-effective and resources implementation and execution of the invention.

The present invention also relates to a proxy network gateway for the formation of an extended proxy information in a mesh network (MNET),

- wire mesh with nodes that are generated as a proxy gateway and/or network station,

- for external alarm MAC address of the external station located outside the mesh network, using the proxy MAC address of the proxy network gateway (G1),

- for specific pairs of the MAC address, the designated proxy address and the external MAC address,

containing:

- the first unit to detect changes in the external connection the station to the proxy network gateway;

- the second block to form, if the detected change, the sequence number proxy information either (i) by the increment of the existing sequence number proxy information for a specific pair of MAC addresses to at least one, or (ii) using the sequence number of the message or item, encoded using the standard Protocol hybrid wireless mesh network, and this sequence number greater than the sequence number RA�it formed a message or item, coded using the standard Protocol hybrid wireless mesh network;

- the third block to form an extended proxy information through:

- first field indicating the addition or removal of compounds, the presence of a third field and the presence of the fifth field;

- the second field that includes an external MAC address;

- the third field, which includes the proxy MAC address, and the presence of a third field specifies the first field;

- the fourth field including a sequence number proxy information;

- the fifth field, including the lifetime of the proxy information, and the presence of the fifth field specifies the first field.

The advantage of this method is that you can avoid misinterpretations of messages that includes a legacy proxy information. This means that the reliability of proxy information available for nodes in a mesh network, may be increased, so as to prevent the forwarding of frames to incorrect proxy network gateways due to outdated proxy information. Other benefits described by the corresponding method.

Serial number proxy information is incremented for the formation of a PXU element (PXU proxy update) with the proxy information, for example, for IEEE 802.11 s, especially� if the lifetime of the proxy information. Another case, which leads to the increment of the sequence number proxy information relates to PXU, which refers to the element proxy of information that needs to be removed corresponding mesh nodes. In the case where the sequence number of the proxy information defined for a specific pair of MAC addresses for the first time, the sequence number of the proxy information can be set to a predefined or arbitrary number. The same applies to the use of HWMP sequence number as the sequence number proxy information.

The proxy gateway may be further improved by using a fourth unit for transmitting the extended proxy information as part of an element or message, encoded using the standard Protocol hybrid wireless mesh network. When using the standard Protocol hybrid wireless mesh network can be provided cost-effective and resources implementation and execution of the invention.

Finally, a part of the invention is a node for reception and execution of advanced information proxy information in a mesh network,

- wire mesh with nodes that are generated as a proxy gateway and/or network station,

- for external alarm MAC address of the external station located outside the mesh network via the proxy MAC �dres proxy network gateway (G1),

- for specific pairs of the MAC address, the designated proxy address and the external MAC address,

containing:

- the first block for receiving an extended proxy information;

- the second block for execution by adding or removing connections to external station with a proxy network gateway specified by the extended proxy information, if the sequence number of the proxy information of the enlarged element proxies more information than the existing sequence number proxy information specific pair of MAC addresses.

The advantage of this knot is that it is possible to avoid incorrect interpretation of messages, including outdated proxy information. This means that the reliability of the proxy elements of information available to the nodes in a mesh network, may be increased, so as to prevent the forwarding of frames to the wrong proxy network gateways due to outdated entries proxy information.

The node can be further improved by the third unit to receive the advanced proxy information as part of the element, encoded using the standard Protocol hybrid wireless mesh network. When using the standard Protocol hybrid wireless mesh network can be provided cost-effective and resources implementation and execution invented�I.

In the context of the present description, the term "proxy information", as known from IEEE standard 802.11 s, is called the proxy information. In addition, the enhanced proxy information is called an advanced proxy information. The term "MAC" is used as abbreviation description Control access to the medium, as determined, for example, in the IEEE 802.3-2002 section 4.1.4, for example, for use in the Ethernet Protocol as the MAC address.

Fig.2 shows a first example of the invention. Wire mesh MNET covers three proxy network node G1, G2, G3, which transmit messages from the field, external to the cellular network, in the inner region and Vice versa. In addition, the wire mesh covers network station STA, which �can be a portable computer user in a mesh network. The second and third proxy gateway G2, G3 and network station STA is also known as other network station M1. In General, the proxy network gateways and network station also known as mesh nodes.

At some point of time the first proxy gateway G1 recognizes external station E1, which can be used to send messages to her and from her. To allow other network stations M1 to send messages to an external station E1, the first proxy gateway G1 informs at least one of the other network stations M1 of the outer stations. Thus, the first proxy gateway G1 generates the advanced proxy information, EPI, based on the following fields F1, ..., F5, see also Fig. 3:

FieldDescription
F1flags, described below;
F2external MAC address EMACA external station E1, for example, the 48-bit MAC address;
F3proxy MAC address PMACA first proxy network gateway G1, for example, the 48-bit MAC address;
F4serial number proxy information, PISN, for example, an integer without sign�;
F5the lifetime of the proxy information, such as an integer without a sign; it is set to the time for which the other network station STA, M1, advanced host proxy information, considers this proxy information is valid; the lifetime of the proxy information is measured in TU (TU is the time unit);

Field F1 defines the specific flags that indicate specific functionality advanced proxy information, EPI:

BitDescription
Position
0It is set to 1 if the proxy information should be removed and set to 0 otherwise. This bit is also known as "subfield removal."

1This so-called subfield "the source is a proxy" specifies that the source (sender) of the extended proxy information, EPI, is a proxy gateway that the proxy information when it is set to 1. In this example, the value 1 indicates the first proxy gateway G1. If it is set to 1, �about advanced proxy information EPI, contains F3. If this subfield is equal to 0, then there is a proxy MAC address.
2This bit indicates whether the advanced proxy information,EPI, information life time proxy information, when set to 1.
3-7Reserved.

In this example, the field is set as follows:

F1=0000.0110 (binary form) (deletion flag is not set, the advanced proxy information is added; a first proxy gateway is the source, the field F3 is not used; field F5 of the lifetime is used)

F2=0x0FFFA100AA00BA (field F2 represents a 48-bit MAC address)

F3 - missing

F4=376 (coded as an unsigned integer)

F5=5000

When the sequence number of the proxy information, PISN, installed for the first time, it can be used with any arbitrary number, for example, 376.

Then the advanced proxy information, EPI, is sent to a network station STA and the second proxy to network gateway G2. This other network station performs the following steps:

if she does not have proxy information for a pair of proxy network gateway G2 - external MAC addresses, which is a specific pair of MAC addresses, SMACAP, she creates this proxy information and sets the proxy network �Luz, external MAC address, serial number proxy information, and the lifetime of the proxy information on the values, as is customary in the advanced proxy information, EPI, this proxy information

- if it has proxy information for a particular set, it updates this proxy information only when the sequence number of the proxy information for the proxy information is greater than the sequence number of the proxy information stored for proxy information. Saved proxy information also known as existing proxy information, EPISN.

Now corresponding to another network station knows that the external station can be reached by a specific external MAC address and using the first proxy gateway G1.

Then second extended proxy information, EPI2, formed the first proxy network gateway, because external station no longer exists, for example, has a mobile device that left the wire mesh. Second extended proxy information, EPI2, is formed as follows:

F1=0000.0011 (binary form) (deletion flag is set; the first proxy gateway is the source, the field F3 is not used, the flag information of the lifetime is not installed, the field F5 is not used)

F2=0x0FFFA100AA00BA (field F2 represents a 48-bit MAC address)

F3 - missing

F4=377 (Ko�varies as an unsigned integer)

F5 - missing

To detect the last extended proxy information sequence number proxy information PISN increases, for example, one or any arbitrary positive value compared with the existing serial number proxy information that was used in previous extended proxy information. Therefore, PSNI=376+1=377.

This second extended proxy information, EPI2, for specific pairs of the MAC address is transmitted on the second and third proxy network gateways network and the station.

When the second extended proxy information EPI2 was adopted by other network stations and the recipient has a valid proxy information stored for a specific pair of MAC addresses, it compares the existing serial number proxy information to the accepted serial number proxy information. If the received serial number proxy information is higher than the existing sequence number proxy information, it will remove the proxy information for a specific pair of MAC addresses. Otherwise, the removal will fail.

If one of the other network stations M1 accepts proxy information with the advanced proxy information should be removed, it may or must register remove proxy information so that it is able t�VAT serial number proxy information with other enhanced elements adopted proxy information for this pair proxy network gateway external MAC address to determine whether the adopted proxy information is newer or older than deleted.

This can be best achieved through the expansion of extended stored proxy information by the deletion flag indicating whether the extended proxy information is valid (added) or invalid (deleted). It is installed in accordance with the deletion flag for the extended proxy information in the accepted proxy update PXU.

After this time, the second proxy gateway G2 sends advanced proxy EPI info, which includes proxy information sequence number PISN=376, the third proxy to network gateway G3. Proxy gateway G3 does not update its stored proxy information for a specific pair of MAC addresses on the basis of advanced proxy information, as received serial number 376 proxy information not more than saved (existing) sequence number 377 proxy information. Therefore, the third proxy gateway G3 retains correct proxy information for specific pairs of MAC addresses and does not accept incorrect proxy information for a specific pair of MAC addresses contained in the latest advanced proxy information from the second proc�and gateway G2.

In another example, the proxy information is transmitted using HWMP IEEE 802.11 (HWMP - Protocol hybrid wireless mesh networks; IEEE - Institute of electrical and electronics engineers). When, for example, the network station STA receives the proxy information of the advanced elements of the proxy information in the HWMP element (address extension is available), it does the following:

- if a network station does not have proxy information for a pair of proxy network gateway - external MAC address (proxy gateway is the address of the network station source (sender) address or network station of the recipient; external MAC address is, for example, an external sender address or the external address of the recipient), it creates this proxy information and sets the proxy gateway, the external MAC address, serial number proxy information, and the lifetime of the proxy information in the appropriate values, as is customary in the HWMP element with this proxy information in accordance with existing regulations. Serial number proxy information is set in HWMP sequence number from a received HWMP element.

- if it has proxy information for a couple proxy gateway - external MAC address, it updates this proxy information only if the HWMP sequence number of a received HWMP element with proxy information is greater than the sequence number of the PPW�and information for the stored proxy information.

The steps of the method described above can be implemented in software, the software may be stored in a storage device such as a CD-ROM, and can be performed at the processing unit. Data can be sent or received through the block IO (IO), which is connected with the processor unit. In addition, the processing unit may be connected to a storage device for storing intermediate data and/or instructions of the software.

In addition, the invention includes a proxy gateway for the formation of an extended proxy information in a mesh network with the following blocks, as shown in Fig. 4:

- the first unit U1 to detect changes in the external connection station E1 with proxy network gateway G1;

- the second unit U2 to form, if the detected change, the sequence number proxy information, PISN, either (i) by the increment of the existing sequence number proxy information, EPISN, for a specific pair of MAC addresses, SMACAP, on at least one or (ii) using the sequence number of the message or item, encoded using the standard Protocol hybrid wireless mesh network, and this sequence number greater than the sequence number of the previously generated messages or element, encoded by�Ohm standard Protocol hybrid wireless mesh network;

- the fourth field F4, which includes the sequence number of the proxy information, PISN;

The proxy gateway may further include a fourth unit U4 to transfer advanced proxy information, EPI, EPI2, as a part of the element, encoded using the standard Protocol hybrid wireless mesh network, and/or the fifth unit U5 for setting a sequence number proxy information sequence number of the element, encoded using the standard Protocol hybrid wireless mesh network.

The blocks U1, ..., U5 can be connected via a bus BUS to exchange data with each other and/or with the processor PROZ and memory unit MEM. In addition, the blocks, the processor and the memory can accept or transmit data through the module IO input / output.

Each�I network station or node G2, G3, M1 for the reception and execution of advanced information proxy information, EPI, EPI2, MNET mesh can contain the following blocks:

- the first block Z1 for receiving the extended proxy information, EPI;

- the second block Z2 for execution by adding or removing connections to external station E1 with proxy network gateway G1 indicated by the extended proxy information, EPI, node G2, G3, M1 only if the sequence number of the proxy information, PISN, advanced proxy information, EPI, EPI2, more than the existing sequence number proxy information, EPISN specific pair of MAC addresses, SMACAP.
