Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
At present, the IP agreement that is adopted in the communication network mainly provides the Routing Protocol of IP-based data traffic between network node, it provides a kind of mobile node that makes to be connected to the mechanism of the ip router node on any link with a permanent IP address, can route a data packet to and may change on the mobile node of position fast always based on this IP agreement.The purpose of this IP agreement initial design is the appearance and the development of complying with the INTERNET technology, the INTERNET technical development so far, can guarantee higher bandwidth and based on wire communication thereby can obtain higher communication quality, add chip and handle the enhancing of capacity, thereby, the pattern of " service of doing one's best " followed for present IP agreement, the application in the INTERNET network does not influence user experience.
Yet cordless communication network is compared with as the wire communication based on the essence of its radio communication, and its bandwidth resources are very valuable, and in practice, the channel of cordless communication network very easily is interfered; And at present the bandwidth of cordless communication network is also well below the bandwidth of INTERNET network; Say that from terminal equipment the handling property of cordless communication network terminal (as mobile phone) is also far away less than personal computer.Therefore, when in cordless communication network, adopting this IP agreement, its service mode of doing one's best of following will highlight sensitive questions such as outage probability is too high, the service time delay is long, thereby have a strong impact on user experience, and make that the cordless communication network utilization rate of channel resources is lower.
For addressing this problem, the inventor herein has creatively proposed the wireless iBUS protocol infrastructure in a kind of cordless communication network, promptly on basis based on the node route pattern of assigned ip data service, and the further scheduling feature of enhanced IP data service.The basis of scheduling is the urgency parameter that generates at the IP data service, basic scheduling thinking is, the IP data service is ranked from high to low according to the urgency parameter, and the IP data service that the priority scheduling urgency is the highest postpones handling the low excessively IP data service of urgency.
With reference to the schematic diagram of wireless iBUS protocol infrastructure shown in Figure 1, in practice, described wireless iBUS agreement mainly acts on home base stations 100, target BS 300 and routing node 200 therebetween.From protocol layer architecture, home base stations 100 and target BS 300 include radio link control layer (rlc layer) 101,301, media access control layer (MAC layer) 102,302 and physical layer 103,303, and each routing node 200 therebetween comprises application layer 201,202, protocol layer 201,204 and key-course 205,206.The function of current IP data service is determined and dispatched according to the urgency parameter to the rlc layer 101 of home base stations 100 in order to finish the urgency parameter; 301 of the rlc layers of target BS 300 correspondingly carry out the function that the targeted customer was resolved and be dispatched to the urgency parameter; The MAC layer 102,302 of home base stations 100 and target BS 300 and the application layer 201,202 of each routing node 200 and protocol layer 203,204 are mutual, in order to carry out the management of channel resource and the mapping of professional and channel at each end (home base stations or target BS) respectively; The physical layer 101,301 of home base stations 100 and target BS 300 is communicated by letter with the physical layer 205,206 of each routing node 200 respectively.
With reference to figure 2, show the flow chart of the dispatching method embodiment 1 of IP data service in a kind of cordless communication network of the present invention, specifically can may further comprise the steps:
The IP data service request that step 11, wireless terminal user are initiated to cordless communication network;
For example, wireless terminal user initiates to carry out the request of visual telephone service or the request of reception Email to 3G network.
The urgency parameter of step 12, the acquisition IP data service of asking;
In embodiments of the present invention, described urgency parameter is mainly used in access control and scheduling, can from network traffics, pick out effective I P data service, with guarantee wireless network resource can Priority Service in effective I P data service, thereby improve the effective rate of utilization of wireless network resource.
Step 13, the described urgency parameter of foundation are dispatched described IP data service.
In specific implementation, can generate the urgency parameter of current IP data service according to presetting rule by home base stations, each intermediate node directly receives the urgency parameter that upper level base station or node transmit and carries out route then, until being transferred to target BS.
As a kind of preferred embodiment, described urgency parameter can adopt following rule to generate:
1) type according to the IP data service generates;
For example, for visual telephone service, it is 0.8 that the urgency parameter is set; For electronic mail service, it is 0.5 that the urgency parameter is set.
2) user gradation according to request IP data service generates;
For example, for VIP user, it is 0.7 that the urgency parameter is set; For domestic consumer, it is 0.3 that the urgency parameter is set.
3) generate according to the type of described IP data service and request user's grade.
For example, for VIP user's visual telephone service, it is 0.56 that the urgency parameter is set; For the visual telephone service of domestic consumer, it is 0.24 that the urgency parameter is set.
According to this urgency parameter rule that data service is dispatched to IP can for:
Rule one: when described urgency parameter is higher than a certain threshold value, preferentially with this IP data service access to wireless communication network;
Rule two: when described urgency parameter is lower than a certain threshold value, in this IP data service of nodal cache, when the cordless communication network channel resource has the free time, the IP data service of described nodal cache will be access in cordless communication network in the mode of first in first out.
In specific implementation, it all is feasible that those skilled in the art adopt the combination of any scheme or these two kinds of schemes, its basic ideas are to give the high IP data service of urgency the preferential configuration of the channel resource of cordless communication network, and the IP data service that urgency is low is at nodal cache, to wait for more suitably scheduling window, utilize idle channel resource to dispatch as far as possible, thereby improve the utilance of wireless communication resources.
As another kind of preferred embodiment, described urgency parameter can also adopt following rule to generate:
In the 1st step,, the maximum service time limit parameter of IP data service is set according to the type of IP data service and/or request user's grade;
In the 2nd step, obtaining to finish the IP data service of asking, to serve the ratio in the maximum service time limit of needed time and this IP data service be the urgency parameter.
For example, according to visual telephone service and electronic mail service request that VIP user A initiates, the maximum service time limit parameter that generates visual telephone service is 100ms, and the maximum service time limit parameter that electronic mail service is set is 200ms; Obtaining the current time of finishing the visual telephone service service is 120ms, and the time of finishing the electronic mail service service is 160ms, and the urgency parameter that then obtains the visual telephone service of user A is 1.2, and the urgency parameter of electronic mail service is 0.8.
With reference to figure 2, in the present embodiment, the rule of dispatching the IP data service according to described urgency parameter is:
Rule one: when described IP data service exceeds its maximum service time limit, or its urgency parameter U abandoned handling this IP data service greater than 1 o'clock, and promptly part shown in 302 is not done queuing among the figure, directly abandons handling;
This situation shows that this IP data service can not finish its needed data service service within its maximum service time limit D, therefore abandons its service.For the IP data service that need just can finish greater than maximum service time limit D, promptly part shown in 301 among the figure is also directly abandoned handling, thereby does not participate in radio channel resource scheduling and transmission, this part resource is saved out, be used for providing service to urgency effective I P data.
Rule two: when described urgency parameter U greater than 0 and less than 1 the time, promptly for the IP data service of part shown in 303 and 304 among the figure, arbitrary routing node that it experienced can will be access in cordless communication network from high to low according to the urgency parameter.When the urgency parameter is 0 or 1, be two critical conditions, urgency is 0, represents that this IP data service finished service in its maximum service within the time limit; Urgency is the maximum service time limit of 1 this IP data service of expression just can satisfy it to serve needed time delay, for the sake of assurance, abandons its processing.
Preferably, can also further mark high risk zone according to the B point between effective category 0 and 1 of urgency in the IP data service, promptly the part shown in 304 among the figure for the IP data service of this part, can be abandoned scheduling and handle; In this case, for the IP data service of optimizing part shown in the zone 303, dispatch and the access to wireless communication network according to the urgency parameter.
In specific implementation, it all is feasible that those skilled in the art can further make up two rules.
For example, be 1.2 in the urgency parameter of the visual telephone service of user A, the urgency parameter of electronic mail service is under 0.8 the situation, then to abandon the packet of user A visual telephone service; Then with the packet buffer memory of electronic mail service to the scheduling queue of present node.Supposing in the scheduling queue of present node institute buffer memory, has following information this moment:
| User profile | IP data service type | The urgency parameter |
| VIP user B | Visual telephone service | 0.95 |
| VIP user A | Electronic mail service | 0.8 |
| The C of domestic consumer | The video downloading service | 0.7 |
According to the urgency parameter from high to low, at first insert the visual telephone service of VIP user B, insert the electronic mail service of VIP user A then, insert the video downloading service of the C of domestic consumer again.
In practice, usually may cause failing to finish the service of current IP data service because of various reasons at a certain node, in this case, as long as do not exceed the maximum service time limit of this IP data service, then can further obtain to finish described IP data service and serve the needed time, with the ratio of remaining time in maximum service time limit of this IP data service, be the urgency parameter of upgrading.
More than the scheduling queue shown in the table is an example, if fail to finish the electronic mail service of VIP user A at present node, and queuing has taken the time of 20ms, then the remaining time in the visual telephone service maximum service time limit of user A is 200ms-20ms=180ms, correspondingly the urgency parameter is updated to 160/180=0.89, and promptly the pairing urgency parameter of the electronic mail service adjusted at the VIP user A of present node buffer memory is 0.89.
This moment then, again according to the urgency parameter of described renewal with the IP data service of present node buffer memory from high to low the access to wireless communication network get final product.In practice, can by this IP data service behind a certain time slot of present node buffer memory, participate in the IP data service scheduling of this node again.
For more effectively utilizing wireless channel, can also form packet at same user's IP data service and dispatch; Perhaps, forming packet at the IP data service of same destination address dispatches; Perhaps, forming packet at the IP data service of same user and same type dispatches.No matter be to adopt frequency division multiple access, code division multiple access, or mix the mode that inserts multiple access, the data set bag can promote the utilization ratio of upstream or downstream link.
With reference to figure 4, show the flow chart of the dispatching method embodiment 2 of IP data service in a kind of cordless communication network of the present invention, specifically can may further comprise the steps:
The IP data service request that step 41, wireless terminal user are initiated to cordless communication network;
In practice, the IP data service can package according to a certain feature, as packaging according to same destination address (for example base station) or same customer service, IP data service after the group bag can be done scheduling queue in the base station, wireless channel is according to timeslot scheduling, the corresponding IP data bag is mapped to concentration of transmissions in the corresponding channel time slot, therefore do not need each packet in the IP data service is dispatched one by one and transmitted, thereby strengthened the utilization ratio of wireless network resource and the dispatching efficiency of wireless IP data service, reduced wireless channel interference probability.
Need to prove that after forming packet, the requirement in its maximum service time limit is all satisfied in each packet in will guaranteeing to wrap when scheduling.
Certainly, the generation scheme of above-mentioned urgency parameter reaches correspondingly, and IP data service scheduling mode only is used as example, those skilled in the art adopt other to generate the urgency parameter and IP data service dispatching method all is feasible, for example, can also and dispatch according to definite urgency parameters such as fairness, channel circumstances, the present invention need not this to be limited.
