Background technology
Present high-speed packet inserts (HSPA, High Speed Packet Access)+in, as subscriber equipment (UE, User Equipment) initially insert the HSPA+ network system after, if when existing data to transmit, by strengthening special uplink channel (E-DCH, Enhanced Dedicated Channel) or E-DCH uplink random access control channel (E-RUCCH, E-DCH Random access UplinkControl Channel) MAC layer-protocol Data Unit (MACe-PDU) bag on is given base station (Node B) with dispatch request information (SI, Scheduling Information) message by the ascending physical signal resource reporting of arbitrary distribution.Include the total buffer status (TEBS of E-DCH in the SI message, Total E-DCH Buffer Status) territory and highest priority logical channel buffer status (HLBS, Highest priority Logical channel Buffer Status) territory, Node B carries out dynamic dispatching (DS according to the information decision that TEBS territory and HLBS territory comprise, Dynamic Scheduling), or semi-persistent scheduling (SPS, Semi-Persistent Scheduling) the active period and the conversion of quiet period, and carry out the transmission of business for UE dispatching uplink stock number.Wherein,
The SPS business is the business of semi-static cyclical transmission, be in a period of time, to remain unchanged in the size of business packet and the time interval of arrival, like this, Node B is disposable allocate ascending physical signal resource (uplink semi-persistent resource) in advance with some cycles and repeat length after, this ascending physical signal resource is monopolistic.
The DS business is the business of dynamic transmission, the professional required ascending physical signal resource (up dynamic resource) of transmission DS constantly sends the scheduling authorization order by Node B and distributes, and once only distribute the ascending physical signal resource that takies one or several subframe, do not distribute periodic resource.
Specifically, TEBS territory in the SI message is used to represent total buffer memory of the logic channel of all scheduled transmission business of UE, the HLBS territory is used for representing that UE has data cached logic channel at present, the buffer memory of highest priority logical channel accounts for the ratio of total UE end buffer memory, promptly with the ratio of TEBS.Wherein, if UE has a plurality of logic channels to have identical limit priority, then HLBS represents that the buffer memory of the logic channel of buffer memory maximum accounts for the ratio of total TEBS.
The situation that only has the DS business for the user, the information that Node B comprises according to TEBS territory and HLBS territory knows that the current UE needs upload the total buffer memory information of DS business and the buffer memory information of highest priority logical channel, and the size of the up dynamic resource amount that needs distribute to UE when determining each dynamic dispatching according to its other resources situation, for example, under the situation of up dynamic resource deficiency, preferentially guarantee the required resource of buffer memory of highest priority logical channel.
For the situation that only has the SPS business, the value in the TEBS territory in the SI message that Node B reports by UE is judged the existing SPS service buffer of UE situation, and infer that with this this SPS business is in active period or quiet period, and determine that when UE being sent semi-static resource reconfiguration order carries out the conversion of active period and quiet period, about Node B specifically how to judge and and decision when carry out the conversion of active period and quiet period, different operators is provided with different algorithms, specifically can not repeat them here referring to the correlation technique document.
By as seen above-mentioned, among the existing HSPA+, UE obtains the technical scheme of ascending physical signal resource by SI reporting message, only be applicable to single S PS business or DS business, the situation that voice and packet data concurrent service is arranged for same UE, for example, professional and the DS business of SPS is arranged simultaneously, the situation that a plurality of SPS business are perhaps arranged, since total buffer memory of the logic channel of all scheduled transmission business of TEBS domain representation UE, and SPS is professional and the DS business all is divided in professional this class of scheduled transmission, and Node B can't know and distinguish the buffer memory of actual DS business and the buffer memory of each SPS business from the SI message that existing UE reports, thereby, for the ascending physical signal resource allocation is made troubles.
Based on the problem of above-mentioned existence, the existing solution that proposes is by being the logic channel of corresponding limit priority with the SPS business setting, and generates SI message, reports to Node B.Like this, Node B can identify the buffer memory of highest priority logical channel by HLBS territory and TEBS territory, it is SPS service buffer amount, buffer memory except that SPS service buffer amount is a DS service buffer amount, thereby make Node B can know and distinguish the buffer memory of actual DS business and the buffer memory of SPS business, and scheduling distribute corresponding ascending physical signal resource.
But above-mentioned is the technical scheme of highest priority logical channel SI reporting message with the SPS business setting, also can only be applicable to and not exist business and the UE higher to have only single SPS service needed transmission in the business that UE need transmit than SPS service priority, for other situation, Node B can not know from the SI message that existing UE reports still and distinguish the buffer memory of actual DS business and the buffer memory of each SPS business that this technical scheme lacks flexibility and autgmentability; In addition, this technical scheme also makes Node B can't know the situation of the highest priority logical channel of DS business, influences Node B to the scheduling of DS business and may cause carrying out the wasting of resources or the resource allocation wretched insufficiency that scheduling resource divides timing.
To sum up describe, the technical scheme of existing UE SI reporting, Node B is difficult to know and distinguishes the buffer memory of the current DS business of UE and the buffer memory of each SPS business, influenced the scheduling of Node B to the DS business, dispatching efficiency is low, and in that being carried out scheduling resource, up DS business divide the timing meeting to cause the inadequate resource of the wasting of resources or distribution, simultaneously, because Node B need decide when carry out the conversion of active period and quiet period by the value in TEBS territory, and under the situation of multi-service especially many SPS business, the conversion of many SPS business is determined in the TEBS territory that can not comprise from the SI message that reports, and judges when up SPS business enters quiet period or active period thereby influenced Node B.
Summary of the invention
In view of this, the invention provides a kind of method of UE reporting scheduling solicited message, the buffer memory of pairing SPS business on the buffer memory of the current DS business of UE and each SPS resource can be known and distinguish to Node B according to this dispatch request information, thereby improve dispatching efficiency and resource utilization, and the buffer memory information when solving the SPS business and when active period and quiet period conversion resource being reshuffled is known problem.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
In the prior art, Node B distributes at type of service when the original allocation resource, different service types is assigned different ascending physical signal resources, for example, UE for needs transmission DS professional 1 and SPS business 2, be assigned up dynamic resource 1 and uplink semi-persistent resource 11, UE sends SI message by up dynamic resource 1 or uplink semi-persistent resource 11 to Node B, TEBS territory in the SI message is total buffer memory of DS waiting for transmission professional 1 and SPS business 2, and the HLBS territory is to be set to the logic channel corresponding cache amount of limit priority and the ratio of total buffer memory.Thereby, in the embodiment of the invention, consider that Node B and UE distinguish the buffer memory information in TEBS territory in the SI message and the ascending physical signal resource of SI reporting message use, dissimilar ascending physical signal resources is only transmitted the corresponding professional SI message of this ascending physical signal resource, what comprise in the SI message is the buffer memory information at the business of this ascending physical signal resource transmission, the i.e. buffer memory of the logic channel of the business transmitted of this ascending physical signal resource of TEBS domain representation wherein, rather than total buffer memory of the logic channel of the business of all ascending physical signal resource transmission of UE, like this, Node B is distinguished, with the situation of change of the traffic carrying capacity of small grain size grasp UE more to business according to the ascending resource of storage in advance and the corresponding relation that transmits type of service it on.
Fig. 1 is the method flow schematic diagram of UE reporting scheduling solicited message of the present invention.Referring to Fig. 1, this flow process comprises:
Step 101, UE obtains the buffer memory information of the business to be transmitted of each ascending resource correspondence;
In this step, business to be transmitted comprise the DS business and/or, the SPS business.Ascending resource (ascending physical signal resource) comprise the up dynamic resource that is used to transmit the DS business and/or, be used to transmit the uplink semi-persistent resource of SPS business.
With existing UE obtain be total buffer memory information of business to be transmitted different be that in the embodiment of the invention, what UE obtained is the buffer memory information of the business to be transmitted of each ascending resource correspondence.For instance, for DS waiting for transmission professional 1 and SPS business 11, UE obtains total buffer memory information of the SPS business 11 of total buffer memory information of DS business 1 of up dynamic resource 1 transmission and 11 transmission of uplink semi-persistent resource respectively.
Step 102, UE writes TEBS territory in the corresponding SI message with the buffer memory information of the business to be transmitted of the ascending resource correspondence obtained, is sent to Node B by this ascending resource.
In this step, the buffer memory information of the DS business to be transmitted of the up dynamic resource correspondence that UE will obtain writes the TEBS territory in the corresponding SI message, be sent to Node B by this up dynamic resource, or, the buffer memory information of the SPS business to be transmitted of the uplink semi-persistent resource correspondence obtained is write TEBS territory in the corresponding SI message, be sent to Node B by this uplink semi-persistent resource.In addition, upload for the up business of DS first, its corresponding SI message is to be uploaded to NodeB by the E-RUCCH channel.
In the practical application, ascending resource may comprise the child resource that is used to transmit a plurality of business, for instance, up dynamic resource 1 is used to transmit DS professional 1 and DS business 2, uplink semi-persistent resource 2 is used to transmit SPS professional 3 and SPS business 4, uplink semi-persistent resource 3 is used to transmit SPS business 5, then in the embodiment of the invention, TEBS territory in the SI1 message comprises total buffer memory of DS professional 1 and DS business 2, TEBS territory in the SI2 message comprises total buffer memory of SPS professional 3 and SPS business 4, and the TEBS territory in the SI3 message comprises total buffer memory of SPS business 5.HLBS territory in the SI message is same as the prior art, does not repeat them here.
Like this, the buffer memory of total DS business and the buffer memory information of each SPS business are carried at respectively in each SI message, by ascending resource transmission separately, the business on concrete resource of each SI message identifier.
So far, the method flow of this UE reporting scheduling solicited message finishes.
Node B can execution in step 103 after receiving the SI message that reports.
Step 103, Node B determine to receive the ascending resource of SI message, carries out ascending resource scheduling according to the ascending resource of storage in advance and corresponding relation and the SI message of transmitting type of service on it.
In this step, as previously mentioned, ascending resource with its on the transmission type of service corresponding relation comprise: up dynamic resource 1 corresponding DS business, uplink semi-persistent resource 2 corresponding SPS business, uplink semi-persistent resource 3 corresponding SPS business.
Node B receives SI1 message, what determine reception SI1 message is up dynamic resource 1, inquire about stored relation in advance, what know this up dynamic resource 1 transmission is the DS business, then according to TEBS territory in the SI1 message and HLBS territory, be professional DS dispatching uplink resource to be transmitted, and upgrade corresponding corresponding relation; Receive SI2 message, what determine reception SI2 message is uplink semi-persistent resource 2, inquires about stored relation in advance, and what know these uplink semi-persistent resource 2 transmission is the SPS business, then, determine whether to carry out the conversion of active period and quiet period according to TEBS territory in the SI2 message and HLBS territory.
Like this, under the situation that the professional parallel transmission of the professional and a plurality of SPS of a plurality of DS is arranged, the buffer memory of the SPS business of correspondence on the buffer memory of the current DS business of UE and each SPS resource can be known and distinguish to Node B according to the ascending physical signal resource that receives each SI message, and carry out ascending resource scheduling at buffer memory corresponding professional on each concrete resource, waste when avoiding ascending resource scheduling and resource allocation are not enough and influence the situation of service transmission rate and quality, can improve dispatching efficiency and resource utilization, can also design the conversion that corresponding process is carried out semi-static resource active period and quiet period configuration according to SPS service buffer amount.
Fig. 2 is the method idiographic flow schematic diagram of UE reporting scheduling solicited message of the present invention.Referring to Fig. 2, this flow process comprises:
Step 201, UE and Node B write down respectively and monitor the buffer memory of the up SPS business of up DS business and each semi-static transmitted over resources;
Step 202, UE and Node B write down each and distribute the pairing type of service of ascending resource, for the professional still SPS business of DS, also are that this ascending resource of mark is the semi-static resource that the dynamic assignment resource still is used to transmit the SPS business.
Step 203 is identified at the buffer memory that TEBS domain representation in the SI message of uploading in the resource that different business distributes should business, the ascending resource by this business correspondence with the SI information reporting to Node B;
In this step, by being arranged on the buffer memory of business that TEBS territory in the corresponding SI message of uploading in the resource that different business distributes only is illustrated in the transmitted over resources of this distribution, rather than in the prior art, SI message has only one, no matter pass through which kind of resource reporting, total buffer memory of all dispatching servicess of UE is all represented in the TEBS territory that wherein comprises.
For instance, when carrying SI message among the MAC-PDU that UE uploads in the semi-static resource of SPS traffic assignments, the TEBS domain representation of SI message is the buffer memory of TEBS domain representation UE SPS business waiting for transmission on this uplink semi-persistent resource in the buffer memory information of the SPS of this semi-static transmitted over resources business.Specifically, if UE has a plurality of SPS business simultaneously, each SPS business has a corresponding semi-static resource, and the buffer memory information of this SPS business at UE is just represented in the TEBS territory in the SI message of carrying among the MAC-PDU that uploads in this semi-static resource so; If UE needs to upload a plurality of SPS business in a semi-static resource, the summation of the buffer memory of these a plurality of SPS business of TEBS domain representation in the SI message of carrying among the MAC-PDU that in this semi-static resource, uploads then.
For the DS business, when carrying SI message among the MAC-PDU that in the ascending resource that the DS service dynamic is distributed, uploads, or when utilizing E-RUCCH to upload SI message, the professional corresponding total buffer memory of logic channel of all DS waiting for transmission of the TEBS domain representation UE in the SI message.
As previously mentioned, in the prior protocols, TEBS domain representation UE holds the buffer memory summation of all scheduled transmission logic channels, comprise all DS service buffer amounts and all SPS service buffer amount and.And HLBS represents the buffer memory of highest priority logical channel and the ratio of TEBS value.
And in the embodiment of the invention, the notion in original TEBS territory has been done one to be redefined, owing to distribute at business during Resources allocation, so on certain resource with the TEBS territory just represent the buffer memory of the pairing business of this resource, rather than total buffer memory, can make Node B can grasp the situation of change of the traffic carrying capacity of UE like this with small grain size more.Further, comprise a plurality of logic channels for same ascending resource, can define the buffer memory of the highest priority logical channel in the business that HLBS represents to transmit on this ascending resource and the ratio of the pairing TEBS value of this ascending resource with maximum buffer memories with equal priority.
Step 204, Node B determine to receive the ascending resource of SI message, according to the ascending resource of storage in advance and the corresponding relation that transmits type of service on it, SI message is carried out ascending resource scheduling.
This step is with step 103.
Fig. 3 is another idiographic flow schematic diagram of method of UE reporting scheduling solicited message of the present invention.Referring to Fig. 3, this flow process comprises:
Step 301 judges whether current subframe receives the SI message that UE reports, if, execution in step 302, otherwise, execution in step 304;
Step 302, Node B inquiry receives the ascending resource of SI message, according to the ascending resource of storage in advance and the corresponding relation that transmits type of service on it, obtains ascending resource corresponding service type;
In this step, in advance Cun Chu ascending resource and on it corresponding relation of transport service be the ascending resource that Node B distributes and the type of service of this ascending resource transmission.
If ascending resource is dynamic dispatching resource or E-RUCCH resource, total buffer memory of DS business waiting for transmission on this dynamic dispatching resource of TEBS domain representation or the E-RUCCH resource in the SI message of then determining to receive, if ascending resource is semi-static resource, the SPS service buffer amount in the SI message of then determining to receive on this semi-static resource of TEBS domain representation.
Step 303 is upgraded corresponding buffer memory information, according to the SI message dispatching uplink resource that receives;
In this step, according to the SI message dispatching uplink resource that receives, its flow process and prior art are similar, different is, in the prior art, what Node B received is a SI message, total buffer memory of the logic channel of all the scheduled transmission business of TEBS domain representation UE in the SI message; And among the present invention, from the ascending resource of each distribution, receiving SI message respectively, the TEBS domain representation UE in the SI message is at total buffer memory of the logic channel of the transport service of this ascending resource correspondence of this ascending resource scheduling.
In the practical application, the complexity that depends on realization, Node B can select not only to write down the corresponding relation of ascending resource and transport service type, can also further write down ascending resource and transmit concrete service logical channels ID number corresponding relation, so that grasp resource and professional corresponding situation in more detail, so that the algorithm design of more optimizing in the future.
Step 304 receives next subframe, returns execution in step 301.
Lift an object lesson below, the present invention is described again.
Fig. 4 is the schematic diagram of UE SI reporting message request scheduling resource among the HSPA+ of the present invention.Referring to Fig. 4, the rectangular block of band shade is represented the semi-static resource 1 at professional 1 distribution of SPS, do not represent the semi-static resource 2 of distributing at SPS professional 2 with the rectangular block of shade, the rectangular block of band shade and arrow is expressed as the dynamic resource that dynamic service distributes, and is with straight line, does not represent the resource that E-RUCCH uploads with the rectangular block of shade.Every kind of piece is represented the pairing resource of different business, for example, the rectangular block of band shade is represented the professional 1 pairing semi-static resource 1 of SPS, has carried among the MAC-PDU that transmits in resource SI message corresponding, the TEBS territory in the SI message then corresponding the buffer memory information of corresponding service.Node B just can grasp the buffer memory information of each different business accurately and carry out the corresponding business scheduling of resource with this.
As seen from the above-described embodiment, Node B and UE distinguish with the physical resource that it reports transmission to use the buffer memory information in the SI message, comprise in the SI message of obtaining on the dissimilar resources at the buffer memory information of different business, UE writes TEBS territory in the corresponding SI message with the buffer memory information of the business to be transmitted of ascending resource correspondence, be sent to Node B by this ascending resource, NodeB determines to receive the ascending resource of SI message, according to the ascending resource of storage in advance and corresponding relation and the SI message of transmitting type of service on it, know and distinguish the up buffer memory information of SPS business on DS business and each semi-static resource, thereby carry out ascending resource scheduling.Like this, on up direction, no matter UE carries out the transmission of how many up SPS business and up DS business simultaneously, can both make Node B know the information of highest priority logical channel in professional total buffer memory of the DS of current UE on up dynamic resource and the DS business exactly, and the buffer memory of knowing the SPS business on each uplink semi-persistent resource of current UE, help scheduling and resource allocation that Node B carries out up DS business exactly, and when the pairing SPS business of each semi-static resource of judging UE carry out the conversion of active period and quiet period, to carry out reshuffling of uplink semi-persistent resource.And the present invention does not need each message format in the agreement is done any change, realizes simple.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
