As shown in Figure 4, show communication means according to another embodiment of the invention, comprising: step 402 receives message frame; Step 404 is obtained the service message Function Identification position in the described message frame, and judges according to the value of described service message Function Identification position whether the transmit leg of described message frame supports the operation of subscription service message and/or the operation of issuing service message; Wherein, the transmit leg of representing described message frame when the value of described service message Function Identification position is first value is only supported the operation of subscription service message, the transmit leg of representing described message frame when the value of described service message Function Identification position is second value is only supported the operation of issuing service message, represents that when the value of described service message Function Identification position is the 3rd value the transmit leg of described message frame supports the operation of subscription service message and issuing service message to operate simultaneously.

In this technical scheme, the transmit leg of message frame and recipient can be mobile phone or flat board, also can be equipment such as router, the chip module that utilizes data among above-mentioned transmit leg and the recipient to handle carries out the generation of message frame and parsing etc., and utilizes signal receiving/transmission device and antenna etc. to realize the transmitting-receiving of message frames.In the NAN network, understand the support situation of operating for service message between many NAN equipment mutually by making, thereby avoided only supporting subscription service message apparatus operating to identify and to be connected to other equipment, also avoid many only to support the NAN equipment of issuing service message operation to issue a large amount of issuing service message at short notice, guaranteed the joint efficiency of equipment room.Particularly, for the value of service message Function Identification position, for " 000000000000000000000000000000000000000000000001 ", show that this equipment only supports the operation of subscription service message such as first value; For " 000000000000000000000000000000000000000000000010 ", show that this equipment only supports the operation of issuing service message such as second value; Be " 000000000000000000000000000000000000000000000011 " such as the 3rd value, show that this equipment is supported to subscribe to simultaneously and the operation of issuing service message.Perhaps, in order to reduce the power consumption of equipment, can suitably shorten the figure place of service message Function Identification position, such as only using 4 bits, then first value is " 0011 " for " 0001 ", second value for " 0010 ", the 3rd value.

Need to prove, though above only introduced the communication equipment 100 among Fig. 1 in the literal and had generation, sent function such as corresponding message frame, and in conjunction with Fig. 2 communication processs such as its concrete generation, transmission have been described; Simultaneously, only introduce the communication equipment 300 among Fig. 3 and had functions such as reception, parsing corresponding message frame, and communication processs such as concrete reception, parsing have been described in conjunction with Fig. 4, but those skilled in the art it should be understood that communication equipment shown in Figure 1 100, the all functions that can have communication equipment 300 as shown in Figure 3 too, and realize the communication process that Fig. 4 describes; Similarly, communication equipment 300 shown in Figure 3 can have all functions of communication equipment 100 as shown in Figure 1 too, and realizes the communication process that Fig. 2 describes, and this obviously is to realize easily on the basis of the disclosed content of the application.

Below in conjunction with Fig. 5 to Fig. 7, to being elaborated based on technical scheme of the present invention.

In the present invention, proposed to inform other equipment by an equipment, about himself support situation for the service message operation, such as whether only supporting the operation of subscription service message or only support the operation of issuing service message or support subscription simultaneously and the operation of issuing service message, thereby avoid having the situation of only supporting the operation of subscription service message or only supporting issuing service message apparatus operating following of current network environment, with the joint efficiency between lifting means.

Especially, the application is at the event handling under the NAN network environment, i.e. information interaction situation between many NAN equipment.

Fig. 5 shows the schematic diagram of data frame format, and Fig. 6 shows the schematic diagram of management frame format.Can see that from Fig. 5 and Fig. 6 both all comprise A(is Address) 1, A2, A3 territory.Though in the prior art, the three has corresponding effect, is used for describing destination address such as the A1 territory, and the A2 territory is used for describing source address; But consider the actual features of NAN network, being equivalent to each NAN equipment independently is connected with other NAN equipment, and do not need the auxiliary of other equipment, the A3 address can not be used in the NAN network so, the service message Function Identification position of NAN equipment can be set so, to show that it is to the support situation of service message operation in A3.

In actual conditions, there are three kinds of situations: only support the operation of subscription service message or only support the operation of issuing service message or support subscription simultaneously and the operation of issuing service message.Describe with regard to above-mentioned three kinds of situations respectively below:

1, only supports subscription service message operation (namely intercepting message)

Under the theoretical case, equipment can adopt the A3 territory in the mac frame of data-message frame, administrative messag frame and/or public administration message frame to place service message Function Identification position, but since the equipment of type discussed herein can be not initiatively the transmission service discovery messages, just by intercepting the service message that other NAN equipment sends, connect with other NAN equipment again, wherein service discovery messages is generally administrative messag frame or public administration message frame, so only consider to identify with the data-message frame service message Function Identification position of this kind equipment usually.

Particularly, because the A3 territory is 6 bytes in existing standard, i.e. 48 bits, only need get two is used as service message Function Identification position, for example identifying NAN equipment with " 000000000000000000000000000000000000000000000001 " only supports the subscription service message function, or for the power saving of NAN equipment, the A3 territory only can be set to 4 bits fully, identify NAN equipment with " 0001 " and only support the subscription service message function.

Because according to existing standard, when certain equipment receives from the data-message frame of other equipment, can directly be resolved to A1, judge whether its destination address is the address of self, if not, then directly abandon, this will cause the recipient of message frame can't determine service message Function Identification position in this message frame.Therefore, the present invention is by setting up following regulation, to avoid above-mentioned situation:

The transmit leg of data-message frame should arrange device type sign position or type of message sign position in the data-message frame, be that NAN equipment or this data-message frame are NAN message to show this transmit leg; Simultaneously, the data-message frame of the recipient of data-message frame to receiving, should at first resolve the device type sign position or the type of message sign position that wherein comprise, determine whether transmit leg is NAN equipment, if, then no matter whether the destination address of its message frame is the address of current receiver, all should parse the service message Function Identification position that comprises in this data-message frame at least.

For device type sign position or type of message sign position, can table 1 specific as follows be set by type field and the subtype territory at the frame control domain of the mac frame of data-message frame:

Table 1

Can utilizing wherein, types value arranges device type sign position or type of message sign position for " 11 ", subtype value are the reservation position of " 0000-".

2, only support issuing service message operation (namely sending message)

This kind equipment only sends the service discovery messages frame, for other NAN equipment, be resolved to the service message frame that sends when being management frames, general parsing that all can be whole is intact, because the administrative messag frame is broadcast message frame in existing standard, the A1 address is broadcast address so, only supports the issuing service message function so A3 only need be set in identifying this type of NAN equipment.For example identifying NAN equipment with " 000000000000000000000000000000000000000000000010 " only supports the issuing service message function, or for the power saving of NAN equipment, the A3 territory only can be set to 4 bits fully, identify NAN equipment with " 0010 " and only support the issuing service message function.

But for some in particular cases, if the address of administrative messag frame is unicast address, so for fear of the situation that can't parse service message operation mark position, can adopt the method described in 1 that is similar to, in the administrative messag frame, add device type sign position or type of message sign position, the service message frame that is sent to show is NAN administrative messag frame, and makes all NAN equipment that listen to this message frame all parse service message operation mark position (as being resolved to the A3 territory) at least.

Table 2

Particularly, as above shown in the table 2, can utilizing wherein, types value arranges device type sign position or type of message sign position for " 00 ", subtype value are the reservation position of " 1111 ".

3, support simultaneously to subscribe to and issuing service message operation (namely intercepting and send message)

When needs inform that other equipment selfs can be carried out the operation of subscription service message, can adopt the mode described in 1; When needs inform that other equipment selfs can be carried out the operation of issuing service message, can adopt the mode described in 2.

Certainly, can in data-message frame or administrative messag frame, add service message Function Identification position, to inform that other equipment selfs can be supported to subscribe to simultaneously and the operation of issuing service message, suppose that then it arranges this service message Function Identification position in the A3 territory of message frame, then for example identifying NAN equipment with " 000000000000000000000000000000000000000000000011 " supports to subscribe to and the issuing service message function simultaneously, or for the power saving of NAN equipment, the A3 territory only can be set to 4 bits fully, identify NAN equipment with " 0011 " and only support the issuing service message function.

Simultaneously, when adopting the issue of data-message frame or administrative messag frame to be the unicast messages frame, still need to adopt the setting for device type sign position or type of message sign position as describing in 1 or 2, can't resolve with the recipient who avoids message frame and obtain service message Function Identification position.

In addition, except data-message frame and administrative messag frame, when equipment need inform that other equipment selfs are supported the operation of issuing service message or supported the operation of subscription and issuing service message simultaneously, can also use as the common action message frame, and corresponding service message Function Identification position is set in this message frame.

As shown in Figure 7, according to an embodiment of the inventionly inform the flow process of the support situation of service message operation as follows mutually at the NAN equipment room:

Step 702, current device A receives the message frame from equipment B.

Step 704, device A are resolved device type sign position or the type of message sign position in the message frame, with the type of the type of determining equipment B or the message frame that receives.

Step 706, if equipment B is NAN equipment, or message frame is the NAN message frame, then enters step 708, otherwise enters step 714.

Step 708, no matter whether the purpose of description address is the address of device A in the A1 territory of message frame, device A all needs to parse at least the service message Function Identification position in the message frame again.

Step 710, concrete numerical value according to service message Function Identification position, determine equipment B to the support situation of service message function, such as only supporting the operation of subscription service message, only supporting issuing service message to operate or support simultaneously the operation of subscription service message and the operation of issuing service message.

Step 712 is carried out subsequent treatment.

Step 714 is resolved the A1 territory of message frame, determines the destination address of this message frame.

Step 716 if the address of current device A then enters step 712, otherwise enters step 718.

Step 718 abandons current message frame.

More than be described with reference to the accompanying drawings technical scheme of the present invention, consider and to determine in the correlation technique that the interior equipment of current network is for the function support situation of service message operation, the invention provides a kind of communication equipment and a kind of communication means, make a plurality of equipment can be well understood to the support situation of operating for service message each other, to avoid only there are a plurality of equipment of supporting subscription or service operations under the current environment, be conducive to promote the efficient of service discovery.

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
