In this technical scheme, the transmit leg of message frame and recipient can be mobile phone or flat board, also can be the equipment such as router, utilize generation and parsing etc. that the chip module of data processing in above-mentioned transmit leg and recipient carries out message frame, and utilize signal receiving/transmission device and antenna etc. to realize the transmitting-receiving of message frame.In NAN network, by making the support situation mutually understood between multiple stage NAN equipment for service message operation, thus the equipment None-identified avoiding only support subscription service Message Opcode can be connected to other equipment, it also avoid multiple stage and only support that the NAN equipment of issuing service Message Opcode issues a large amount of issuing service message at short notice, ensure that the joint efficiency of equipment room.Particularly, for the value of service message Function Identification position, such as the first value is " 000000000000000000000000000000000000000000000001 ", shows that this equipment only supports subscription service Message Opcode; Such as the second value is " 000000000000000000000000000000000000000000000010 ", shows that this equipment only supports issuing service Message Opcode; Such as the 3rd value is " 000000000000000000000000000000000000000000000011 ", shows that this equipment is supported to subscribe to and issuing service Message Opcode simultaneously.Or in order to reduce the power consumption of equipment, suitably can shorten the figure place of service message Function Identification position, such as only using 4 bits, then the first value is that " 0001 ", second is worth for " 0010 ", the 3rd value are " 0011 ".

It should be noted that, although above in word the communication equipment 100 only described in Fig. 1 there is generation, send the functions such as corresponding message frame, and composition graphs 2 describes the communication processs such as its concrete generation, transmission; Simultaneously, the communication equipment 300 only described in Fig. 3 has reception, resolves the functions such as corresponding message frame, and composition graphs 4 describes the communication processs such as concrete reception, parsing, but those skilled in the art it should be understood that the communication equipment 100 shown in Fig. 1, the all functions of communication equipment 300 as shown in Figure 3 can be had too, and realize the communication process of Fig. 4 description; Similarly, the communication equipment 300 shown in Fig. 3, can have all functions of communication equipment 100 as shown in Figure 1 too, and realizes the communication process of Fig. 2 description, and this is on the basis of content disclosed in the application, is obviously easily to realize.

Below in conjunction with Fig. 5 to Fig. 7, be described in detail to based on technical scheme of the present invention.

In the present invention, propose and inform other equipment by an equipment, about the support situation that himself operates for service message, such as whether only support subscription service Message Opcode or only support issuing service Message Opcode or support to subscribe to and issuing service Message Opcode simultaneously, thus avoid the situation that only there is the equipment only supported subscription service Message Opcode or only support issuing service Message Opcode under current network conditions, with the joint efficiency between lifting means.

Especially, the application for the event handling under NAN network environment, the information interaction situation namely between multiple stage 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 from Fig. 5 and Fig. 6, both all comprise A(and Address) 1, A2, A3 territory.Although in the prior art, three has corresponding effect, and such as A1 territory is for describing destination address, and A2 territory is for describing source address; But consider the actual features of NAN network, be equivalent to each NAN equipment independently with other NAN equipment connection, and do not need the auxiliary of other equipment, so A3 address can not be used in NAN network, the service message Function Identification position of NAN equipment so can be set in A3, to show its support situation operated service message.

In a practical situation, there are three kinds of situations: only support subscription service Message Opcode or only support issuing service Message Opcode or support to subscribe to and issuing service Message Opcode simultaneously.Just above-mentioned three kinds of situations are described respectively below:

1, only subscription service Message Opcode (namely intercepting message) is supported

Under 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 because the equipment of type discussed herein can not transmission service discovery messages initiatively, 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 usual consideration data-message frame identifies the service message Function Identification position of this kind equipment.

Particularly, because 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 subscription service message function, or in order to the power saving of NAN equipment, A3 territory only can be set to 4 bits completely, identify NAN equipment with " 0001 " and only support subscription service message function.

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

The transmit leg of data-message frame, should arrange device type flag or type of message flag in data-message frame, to show that this transmit leg is for NAN equipment or this data-message frame are for NAN message; Simultaneously, the recipient of data-message frame is to the data-message frame received, first the device type flag or type of message flag that wherein comprise should be resolved, 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 at least should parse the service message Function Identification position comprised in this data-message frame.

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

Table 1

The reservation position that wherein types value is " 11 ", subtype value is " 0000-" can be utilized, device type flag or type of message flag are set.

2, only issuing service Message Opcode (namely sending message) is supported

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

But for some in particular cases, if the address of administrative messag frame is unicast address, so in order to avoid the situation of service message operation mark position cannot be parsed, the method be similar to described in 1 can be adopted, device type flag or type of message flag is added in administrative messag frame, to show that sent service message frame is for NAN administrative messag frame, and all NAN equipment listening to this message frame is made all at least to parse service message operation mark position (as being resolved to A3 territory).

Table 2

Particularly, as above shown in table 2, the reservation position that wherein types value is " 00 ", subtype value is " 1111 " can be utilized, device type flag or type of message flag are set.

3, support to subscribe to and issuing service Message Opcode (namely intercept and send message) simultaneously

When needs inform that other equipment self can perform subscription service Message Opcode, the mode as described in 1 can be adopted; When needs inform that other equipment self can perform issuing service Message Opcode, the mode as described in 2 can be adopted.

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

Simultaneously, when adopting the issue of data-message frame or administrative messag frame to be unicast messages frame, still needing to adopt the setting for device type flag or type of message flag as described in 1 or 2, cannot resolve to avoid the recipient of message frame and obtaining service message Function Identification position.

In addition, except data-message frame and administrative messag frame, when equipment needs to inform that other equipment self are supported issuing service Message Opcode or supported subscription and issuing service Message Opcode simultaneously, can also use as 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 mutually inform the flow process of support situation of service message operation as follows at NAN equipment room:

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

Step 704, device A resolves device type flag in message frame or type of message flag, with the type determining equipment B or the type of message frame received.

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

Step 708, whether the destination address described in the A1 territory of no matter message frame is the address of device A, and device A all needs the service message Function Identification position parsed at least again in message frame.

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

Step 712, performs subsequent treatment.

Step 714, resolves 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 in correlation technique that the function that the equipment cannot determined in current network operates for service message supports situation, the invention provides a kind of communication equipment and a kind of communication means, make multiple equipment can be well understood to each other for the support situation of service message operation, under avoiding current environment, only there are the multiple equipment supporting subscription or service operations, be conducive to the efficiency promoting service discovery.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
