Description
Technical field
The message transmitting method that the invention relates to a kind of control device and be used for this control device is more specifically said so and can directly be transmitted world-wide web IGMP (internet group management protocol about a kind of; IGMP) control device of report and the message transmitting method that is used for this control device.
Background technology
Along with the progress of science and technology and the development of information industry, computer and network occupies indispensable status in daily life.For example, with the various data of Computer Processing or with the various information of Web search, shopping and exchanges data or the like, all be the habitual life styles of the mankind.In recent years; Since wireless network have do not need physical network wiring with and the mobility advantages of higher; Therefore wireless network also more and more receives people's attention, to develop the most global microwave access interworking protocol (worldwide interoperability formicrowave access now; WiMAX) wireless network is an example, and it can support the wireless Internet access under the high-speed mobile, and the while is the support voice function further.
And in wireless network; No matter be that mobile phone or luggable computer all can be considered a kind of mobile device or a kind of travelling carriage (mobile station); When travelling carriage is prepared when wireless network is obtained the service (for example web page browsing) of application-specific, promptly can require to set up the wireless connections (connection) relevant to the base station of its corresponding connection (base station) with web page browsing.Because when carrying out web page browsing; Be not to carry out transfer of data constantly between travelling carriage and the base station; Therefore between travelling carriage and base station, do not carry out in the transfer of data, travelling carriage just can get into an idle mode (idle mode) to save the consumption of its electric power.
In addition, because the user of network increases day by day, thereby the use amount of network bandwidth (bandwidth) and the network address (network address) also heightens thereupon.For solving this problem, any wireless network services provider and Wireless Communication Equipment manufacturer just proposed the to multicast notion of (multicast) reduces the use amount of network bandwidth with this technology.For example; Obtain the data of Chinese Central Television's program through wireless network when a plurality of user's desires that are connected on the different base station; The method that known technology will use single propagation (unicast) is sent to these base stations with man-to-man mode respectively with the data of Chinese Central Television's program, is transferred to each user more respectively; If use the method that multicasts; These desires obtain the data of Chinese Central Television's program through wireless network user will be regarded as the member (membership) of same colony (Group); The member who belongs to same colony can receive the data of representing this group network address, and the data of Chinese Central Television's program then can use the mode of colony's broadcasting to be sent to these users once.Hence one can see that, transmits data once to a plurality of users with the mode that multicasts, and then reduce the use amount of the network bandwidth and the network address significantly.
If prepare to build put one have function of multicasting and idle mode simultaneously wireless network, then need in this wireless network, to add the IGMP framework to reach the function that multicasts.As shown in Figure 1, it is one to have the wireless network 1 of IGMP framework, and it comprises a multicast system 11 and a plurality of travelling carriage 13,15,17,19.Then store the tabulation that multicasts in the multicast system 11, this tabulation that multicasts then stores in the wireless network 1 the existing group that multicasts at present.For example; If in wireless network 1, there are two kinds of data sending, one is the data of Chinese Central Television's program (figure does not illustrate); Another then is the data of Phoenix Satellite TV program (figure does not illustrate); In the tabulation that multicasts, will write down two groups that multicast, the group that multicasts wherein is set to Internet protocol (internetprotocol is hereinafter to be referred as the IP) address of sending Chinese Central Television's program data; Another group that multicasts then is set to the IP address of sending the Phoenix Satellite TV program data.
In more detail, if travelling carriage 13,15 receives only Chinese Central Television's program data, then travelling carriage 13,15 will be added to the group that multicasts that belongs to Chinese Central Television's program; And if travelling carriage 17 receives only the Phoenix Satellite TV program data, then travelling carriage 17 will be added to the group that multicasts that belongs to the Phoenix Satellite TV program; If travelling carriage 19 is to receive Chinese Central Television's program data and Phoenix Satellite TV program data, then travelling carriage 19 will be added to the group that multicasts that multicasts group and belong to the Phoenix Satellite TV program that belongs to Chinese Central Television's program.
After travelling carriage 13,15,17,19 receives IGMP request signal 110 and IGMP request signal 112 respectively; Travelling carriage 13,15 will be responded an IGMP report signal 130 and 150 times multicast systems 11 of an IGMP report signal respectively to IGMP request signal 110; Inform multicast system 11, travelling carriage 13,15 still need receive Chinese Central Television's program data; Travelling carriage 17 will be responded IGMP report signal 170 a to multicast system 11 to IGMP request signal 112, inform multicast system 11, and travelling carriage 17 still need receive the Phoenix Satellite TV program data; And travelling carriage 19 will respond IGMP request signal 110 respectively and IGMP request signal 112 is responded an IGMP report signal 190 and IGMP report signal 192 a to multicast system 11; Inform multicast system 11, travelling carriage 19 still need receive Chinese Central Television's program data and Phoenix Satellite TV program data.By this, the multicast system 11 of wireless network 1 will be able to successfully reach the function that multicasts.
The travelling carriage of wireless network 1 is behind the IGMP request signal that receives multicast system 11 transmissions, and all necessary loopback IGMP report signal is to multicast system 11.If one be in idle mode travelling carriage receive the IGMP request signal, leave idle mode just must come and go through a large amount of control signals, rebulid data channel simultaneously, with loopback IGMP report signal.Travelling carriage if need not receive other data, will get into idle mode once again after having sent the IGMP report signal.Regularly send under the situation of IGMP request signal at multicast system 11, travelling carriage will leave/get into idle mode continually.In view of the above, leave the unnecessary waste that a large amount of control signals that idle mode transmits will cause the frequency range of wireless network, simultaneously,, the power consumption that causes travelling carriage is heightened if travelling carriage leaves/get into idle mode continually for making travelling carriage.
Please continue to consult Fig. 2, it is to illustrate between multicast system 11 and the travelling carriage 17, the sketch map that signal transmits.Multicast system 11 comprises a base station 111, an Access Network service (access network service; ASN) gateway 113, a call controller (paging controller; PC) 115 and one validator (authenticator) 117.When travelling carriage 17 is in an idle mode, represents it only can receive and multicast signal and can not send signal.And the tabulation that multicasts of multicast system 11 promptly is stored in the ASN gateway 113.When travelling carriage 17 receive IGMP request signal 110 that ASN gateway 113 sent through base station 11, after 112; Travelling carriage 17 must leave idle mode in advance and rebulid data channel, to respond an IGMP report signal 170 to ASN gateways 113 to IGMP request signal 112.
Therefore; Travelling carriage 17 will send a correction earlier and require signal 210 to base station 111; When base station 111 receive revise require signal 210 after; To send idle jumping out and require signal 230 to ASN gateways 113, and make ASN gateway 113 learn that travelling carriage 17 prepares to exit idle mode, ASN gateway 113 will leave unused to jump out and require signal 230 to transfer to call controller 115 simultaneously; Call controller 115 will respond idle jumping out and require signal 230, carry out one of travelling carriage 17 with validator 117 and write down exchanger (context exchangeprocedure) 290.
After the record exchanger 290 between call controller 115 and the validator 117 is finished, call controller 115 will transmit idle response signal 270 to the ASN gateways 113 of jumping out.ASN gateway 113 promptly passes on to leave unused jumps out response signal 270 to base station 111.When base station 111 receive idle jump out response signal 270 after; To transmit a channel registration and require signal 232 to ASN gateways 113; Receive a channel registration response signal 250 of sending subsequently again, to rebulid the data channel of travelling carriage 17 by ASN gateway 113.After the data channel of travelling carriage 17 was set up, base station 111 was sent one immediately and is revised response signal 234 to travelling carriage 17, makes travelling carriage 17 leave idle mode.Travelling carriage 17 sends IGMP report signal 170 to ASN gateways 113 through base station 111 subsequently.Thus, travelling carriage 17 is in receiving IGMP request signal 110, after 112, can leave idle mode, and passback IGMP report signal 170 to ASN gateways 113.
Be the frequency range waste of reduction wireless network and the power consumption of travelling carriage; Known technology has proposed two solutions; One has delayed delivery time of an IGMP report signal separately for the travelling carriage of wireless network 1; After receiving an IGMP request signal, send the IGMP report signal with the travelling carriage avoiding belonging to same group simultaneously, cause the frequency range waste of wireless network; Another then sends the IGMP report signal for needing only a travelling carriage with broadcast mode; The travelling carriage that all the other and this travelling carriage belong to same group does not then need to send the IGMP report signal again; Avoiding travelling carriage to need constantly to jump out, and then increase the power consumption of travelling carriage from idle state.
In wireless network 1; The travelling carriage 13,15,19 that belongs to rating group of the Chinese Central Television (CCTV) is example; Suppose that delayed delivery time that travelling carriage 13 has is delayed delivery time that 1 second, travelling carriage 15 have is that the delayed delivery time that 2 seconds and travelling carriage 19 have is 3 seconds; After travelling carriage 13,15,19 receives IGMP request signal 110; Because the delayed delivery time that travelling carriage 13 has is 1 second, travelling carriage 13 will take the lead in sending IGMP report signal 130 with the mode of broadcasting, and travelling carriage 15,19 is after receiving IGMP report signal 130; Just do not need to send separately again IGMP report signal 150 and IGMP report signal 190, need the probability of jumping out from idle state with reduction travelling carriage 15,19.Yet so the practice probability that still can't make travelling carriage 13 jump out from idle state reduces.
In sum, regularly send under the situation of IGMP request signal at multicast system 11, travelling carriage will leave/get into idle mode continually, and this will cause the unnecessary waste of the frequency range of wireless network, also cause the power consumption of travelling carriage to heighten.In view of the above; To how to have in the wireless network of function of multicasting and idle mode at the same time; Make travelling carriage after regularly receiving the IGMP request signal, do not need to pass in and out idle mode continually because of replying the IGMP report signal, this is the problem that the dealer in this field needs solution badly.
