In the present embodiment, base station is BCCH ＞ PCCH ＞ CCCH ＞ SC-MCCH ＞ to the integrated scheduling order of each channel DCCH ＞ DTCH (business datum on DTCH channels dispatched herein is the re-transmission data of point-to-point service) ＞ SC-MTCH ＞ DTCH (business datum on DTCH channels dispatched herein is the first biography data of point-to-point service).To the cluster on SC-MTCH The scheduling of business is prior to the point-to-point scheduling for just passing business on DTCH, it is ensured that the transmission quality of group service.
Below by the explanation to step S101~step S104, to how to cause in the present embodiment on SC-MTCH The scheduling of group service is prior to the point-to-point scheduling for just passing business on DTCH is described in detail.
In S101, core net issues group service data and point-to-point business datum to base station, the base station that just pass receives collection Group business data and point-to-point just biography business datum, group service data pass through SC-MTCH transmissions, point-to-point just to pass business Data pass through DTCH transmissions.
For S102, group service data are received in base station and point-to-point are just passed after business datum, it is necessary to by cluster industry Business data and the point-to-point business datum that just passes make a distinction, to respectively obtain group service data and point-to-point just biography business number According to.Either group service data or point-to-point just biography business datum, it is required for establishing carrying, each carrying will select one Individual Traffic Channel-DTCH or SC-MTCH, if selection DTCH is exactly point-to-point just biography business, it is exactly cluster industry to select SC-MTCH Business, carrying have determined that these attributes when foundation, and each business datum carries the attribute information of carrying, therefore, base station The attribute information for the carrying that can be carried by the business datum of acquisition distinguishes group service data and just passes business number with point-to-point According to.
In S103, obtain group service data and after point-to-point just biography business datum, base station is it needs to be determined that group service Qos priority with it is point-to-point just pass business Qos priority.In particular it is required that so that the Qos priority of group service is higher than The point-to-point Qos priority for just passing business；Because it is wide that multiple monitoring users reception SC-MTCH are might have under a cluster user Business is broadcast, therefore, only the Qos priority of guaranteed group service just can guarantee that higher than the point-to-point Qos priority for just passing business The transmission quality of group service, such as the Qos of cluster voice are higher than the Qos of common point-to-point voice, and the Qos of cluster video will Higher than the Qos of common point-to-point video.
In S104, after Qos priority of the Qos priority higher than point-to-point just biography business of group service is ensured, base Qos priority and the point-to-point Qos priority for just passing business stood according to group service are group service data and point-to-point first Business datum distribution PDCCH and PDSCH interface-free resources are passed, to cause the transmission preferences of group service data just to pass industry in point-to-point The transmission for data of being engaged in.That is base station is preferably that group service data distribution PDCCH and PDSCH interface-free resources are transmitted, Then it is transmitted again for the point-to-point business datum distribution PDCCH and PDSCH interface-free resources that just pass, ensure that the biography of group service Transmission quality.
The dispatching method based on SC-MTCH of the present embodiment includes：Receive single cell broadcast traffic channel SC-MTCH and specially With the business datum on Traffic Channel DTCH；The attribute information of the carrying carried according to business datum, obtains group service data Business datum is just passed with point-to-point；The Qos priority of group service and the point-to-point Qos priority for just passing business are determined, wherein, The Qos priority of group service is higher than the point-to-point Qos priority for just passing business；According to the Qos priority and point of group service Qos priority to passing business at the beginning of point, it is that group service data and point-to-point just biography business datum distribution PDCCH and PDSCH are empty Mouth resource, to cause the transmission preferences of group service data in the point-to-point transmission for just passing business datum, to ensure that group service Transmission quality.
Below to " determining that the Qos priority of group service and the point-to-point Qos for just passing business are preferential in a upper embodiment The specific implementation of level " is described in detail.
A kind of mode that can realize is：The priority of group service is obtained, the priority of group service includes the first base This priority and the first special priority；Obtain the point-to-point priority for just passing business, the point-to-point priority bag for just passing business Include the second base priority and the second special priority；Judge whether the first base priority is higher than the second base priority, if It is no, then set is carried out on the default position of the first special priority, set is used to indicate that the Qos priority of group service is higher than point Qos priority to passing business at the beginning of point, if so, then without any operation.
Specifically, the embodiment is substantially excellent by the second of the base priority of group service first and point-to-point just biography business After first level obtains, first compare the first base priority and the second base priority, if the first base priority is basic more than second Priority, illustrate the Qos priority of group service natively higher than the point-to-point priority for just passing business, without any behaviour Make, base station will be preferably group service data distribution PDCCH and PDSCH interface-free resources to carry out business transmission.Only when When one base priority is less than or equal to the second base priority, just to being put on the default position of the first special priority of group service Position, even if the default position is changed into 1 from 0 so that the Qos priority of group service is higher than the point-to-point Qos priority for just passing business, So that base station is preferably group service data distribution PDCCH and PDSCH interface-free resources to carry out business transmission.The embodiment is fitted The less situation of business datum amount for transmission.
The mode that another kind can be realized is to obtain the priority of group service, and the priority of group service includes first Base priority and the first special priority；Obtain the point-to-point priority for just passing business, the point-to-point priority for just passing business Including the second base priority and the second special priority, set is carried out on the default position of the first special priority, set is used It is higher than the point-to-point Qos priority for just passing business in the Qos priority of instruction group service.
Specifically, the embodiment is substantially excellent by the second of the base priority of group service first and point-to-point just biography business After first level obtains, the first base priority and the second base priority are not compared, directly first in group service is special preferential The default position superset of level, even if the default position is changed into 1 from 0 so that the Qos priority of group service just passes industry higher than point-to-point The Qos priority of business.The embodiment is suitable for the more situation of the business datum amount of transmission.
Wherein, because uplink feedback is not present in SC-MTCH, thus group service base priority calculate do not consider it is descending Quality of wireless channel f (Δ CQI), the base priority of group service are obtained according to formula one：
Priority=f (delay) × Kpf+ rand_num formula one
The point-to-point base priority for just passing business is obtained according to formula two：
Priority=f (Δ CQI) × f (delay) × Kpf+ rand_num formula two
Wherein, f (Δ CQI) is channel factors, is calculated according to the CQI that terminal is fed back, and momentary channel quality is better, should Value is bigger；F (delay) is time delay factor：Current bearer delay requirement is higher, and real-time measuring data time delay is bigger, this because Subvalue is higher；KpfTo connect dispatching priority comparative factor, held for ensureing that dedicated bearer calculates priority value higher than non-dedicated Carry；Rand_num belongs to random number.F (Δ CQI), f (delay) and KpfAcquisition methods use method of the prior art, Rand_num is used for f (delay) × K in the base priority of two group services of calculatingpfWhen consistent, randomly select different Rand_num so that the base priority of two group services is different, or in the substantially excellent of two point-to-point just biography business of calculating During first level, f (Δ CQI) × f (delay) × KpfWhen consistent, different rand_num is randomly selected so that two point-to-point just biographies The base priority of business is different.
In order to be further ensured that the transmission quality of group service, it is necessary to which so that group service uses low bit- rate in PDSCH Transmission, in order to ensure that group service data use low bit- rate transmission, it is necessary to which so that PDCCH pattern is DCI1A mould in PDSCH Formula, resource allocation is carried out by the way of single current, and PDCCH aggregation levels are configured, wherein the original of aggregation levels configuration Then to ensure that business datum is transmitted in PDSCH using low bit- rate；The modulating mode for also requiring that PDSCH is QPSK mode, And modulation is configured with coding strategy (Modulation and Coding Scheme, abbreviation MCS) exponent number, wherein MCS The principle that exponent number is set will ensure that business datum is transmitted in PDSCH using low bit- rate.
