Below in conjunction with accompanying drawing, be described in detail as follows:
Shown in Fig. 2 and Fig. 3 a, the invention provides a kind of multi-mode radio network interface card that receives and handle the different radio signal.A kind of multi-mode radio network interface card 1, it can receive and handle the packet information of multiple different radio agreement simultaneously, and carries out wireless transmission individually or simultaneously.
Wherein, this multi-mode radio network interface card 1 is combined by antenna 111, a multi-mode radio module 12, a multi-mode antenna 121, a medium access control layer 13, an external memory storage 131 and a bridging interface 14 that a radio module 11, is used for WLAN.
Wherein, this radio module 11 is used to change the wireless signal of 802.11 communication protocols, and as the approach that transmits packet information between antenna 111 that is used for WLAN and the medium access control layer 13.
This antenna 111 that is used for WLAN is used to receive or send the wireless signal of 802.11 communication protocols, and as the media that transmits wireless signal between this multi-mode radio network interface card 1 and the radio area network 3.
This multi-mode radio module 12 is used to change the wireless signal of other wireless agreements, and as the approach that transmits packet information between multi-mode antenna 121 and the medium access control layer 13; In addition, this multi-mode radio module 12 can be according to the demand of user or environment, and sets and replace to different wireless communication protocol (for example: GPRS, 802.11, BlueTooth, CDMA etc.).
This multi-mode antenna 121 is used to receive or send the wireless signal of other wireless agreements, and as the media of this multi-mode radio network interface card 1 with wireless signal base station 4 transmission packet information.With aforementioned multi-mode radio module 12 in like manner, this multi-mode antenna 121 also can be according to the demand of user or environment, and sets or replace to different wireless communication protocol (example: GPRS, BlueTooth, CDMA etc.).
802.11 packet information that this medium access control layer 13 is used for individual treated and reads radio module 11, or individual treated and the packet information or the packet information that read other wireless agreements of multi-mode radio module 12.
This external memory storage 131 is used to read and the packet information of temporary other wireless agreements, when making medium access control layer 13 handle 802.11 packet information, the packet information of other wireless agreements can be waited for and be temporary, thereby can not influence the work of medium access control layer 13, or cause the packet information of other wireless agreements to be conflicted mutually, and then avoided clogging with 802.11 packet information.
This bridging interface 14 is as the approach that packet information is transferred to host computer 2; This bridging interface 14 also can be according to the demand of environment, and is arranged to different interface (example: PCMCIA, CF, USB etc.).
Shown in Fig. 3 a and Fig. 3 b, be GPRS package of the present invention and WLAN package enforcement view and GPRS package of the present invention and WLAN package transmission schematic flow sheet.As seen, to receive and handle the transfer process of different radio communications protocol packet information simultaneously as follows for this multi-mode radio network interface card 1:
It mainly is multi-mode radio module 12 and the multi-mode antenna 121 that this multi-mode radio module 12 and multi-mode antenna 121 is provided with, changes to the wireless communication protocol that can transmit the GPRS packet information;
This multi-mode radio network interface card 1 is like this transmission from the packet information of radio area network 3: the wireless signal that receives or send 802.11 communications protocols by the antenna 111 that is used for WLAN, and the wireless signal that receives transferred to radio module 11, utilize this radio module 11 that wireless signal is converted to packet information, and packet information is sent to medium access control layer 13, again by the agreement sublevel of these medium access control layer 13 controls to the access of essence transfer medium, and the processing of 802.11 packet information, provide transmission packet information approach by bridging interface 14 at last, this packet information is sent to host computer 2.Like this, just make host computer 2 be connected on the radio area network 3, the user just can browsing page or transmission information.
Meanwhile, this multi-mode radio network interface card 1 is to make between GPRS signal base station 4 and the host computer transmission information mutually like this: at first receive or send the GPRS signal by multi-mode antenna 121, and the GPRS signal that receives transferred to multi-mode radio module 12, utilize this multi-mode radio module 12 that the GPRS signal is converted to packet information, and the GPRS packet information is sent to external memory storage 131, utilize external memory storage 131 temporary GRPS packet information, so just can be when medium access control layer 13 work be busy, temporary GPRS signal and wait, thereby neither can influence the work of medium access control layer 13, can not cause the GPRS packet information to be conflicted mutually again with 802.11 packet information; And then the agreement sublevel that utilizes this medium access control layer 13 to handle to the access of essence transfer medium, and the packet information of reading external memory 131, provide transmission GPRS the approach of packet information by bridging interface 14 at last, the GPRS packet information is sent to host computer 2.Like this, just make host computer 2 be connected on the GPRS signal base station 4, the user just can browsing page or message transmission.
And, this multi-mode radio module 12 and multi-mode antenna 121 also can be provided with, change to the multi-mode radio module 12 and the multi-mode antenna 121 that can transmit different wireless communication protocol (example: BlueTooth, CDMA etc.), make its this multi-mode radio network interface card 1 can transmit and handle different radio agreement signal.
Combination utilization by above-mentioned member, this multi-mode radio network interface card 1 just can receive 802.11 packet information with radio module 11 by the antenna 111 that is used for WLAN, or utilize multi-mode radio module 12 and multi-mode antenna 121 to transmit and conversion GPRS signal, read by external memory storage 131 again and temporary GPRS packet information, by medium access control layer 13 individual treated GPRS packet information and 802.11 packet information, by bridging interface 14 this packet information is offered host computer 2 at last then.As seen, this scheme of the present invention neither can influence the work of medium access control layer 131, and cause the GPRS packet information to be conflicted mutually with 802.11 packet information, can transmit or receive packet information again simultaneously from radio area network 3 or GPRS signal base station 4, but also can reduce internal structure cost and reduced volume in a large number, and then have the cost of saving and portable characteristics.
In order to be illustrated more clearly in the present invention compared with prior art, the progressive that has and practicality, it is as follows now to do a comparative analysis:
The shortcoming of prior art is:
1. member is many, volume big, carry inconvenience;
2. cost is higher, and is unfavorable to the consumer;
3. do not have a practicality.
Advantage of the present invention is:
1. member is few, volume is little, carrying convenience;
2. cost is lower;
3. utilize external memory storage to keep in packet information, can avoid packet information mutually to conflict;
4. but the packet information of the multiple different radio communications protocol of individual treated;
5. has practicality;
The above specific embodiment only is explanation technical scheme of the present invention, and can not be used for limiting the present invention.
