Step S202, access network elements determine the data transmission period of the business datum of terminal.
Step S204, access network elements are the entry-into-force time of terminal configuration SR resource and SR resource according to data transmission period, and wherein SR resource and entry-into-force time are used to indicate terminal and only are allowed to use the SR resource to send SR in the entry-into-force time.
Step S206, access network elements sends to terminal with SR resource and the entry-into-force time of configuration.
In the correlation technique, terminal takies the SR resource always, thereby causes the service efficiency of SR resource not high.In the embodiment of the invention, by configuration cycle SR resource and entry-into-force time thereof, can guarantee that on the one hand this terminal sends SR in entry-into-force time life cycle SR resource, thereby do not affect the throughput of this terminal, do not increase extra signaling consumption, can guarantee that on the other hand the time of this cycle SR resource beyond the entry-into-force time used by other terminal, thereby improve the service efficiency of SR resource.
In addition, can carry out timely and effectively when needs carry out transfer of data in order to guarantee this terminal, the present invention has taken into full account the application reality of current terminal, and proceed from the reality, data transmission period according to the terminal traffic data is configured cycle SR resource and entry-into-force time thereof, and the below is elaborated.
At present, the business datum of terminal mainly concentrates on line service (such as microblogging, mobile phone QQ, FaceBook etc.).These require terminal to remain on for a long time line states at line service usually; namely; even if the user does not have transmission information; this class also can periodically send keep-alive packet (its transmission cycle normally reaches tens of seconds to several minutes) at line service, to keep the application layer link between terminal and the service provider's server.Therefore, this application layer behavior will keep RRC to connect so that terminal is connected with network side just, thereby so that network side disposes SR resource to terminal keeps always and can't discharge.
Among the present invention, according to the transmission cycle of above-mentioned keep-alive packet, predict the data transmission period of terminal, then according to data transmission period configuration cycle SR resource and entry-into-force time thereof.Like this, when follow-up keep-alive packets need sent, cycle SR resource exactly came into force in its entry-into-force time, thereby can guarantee that this keep-alive packet transmits timely and effectively.
For the data transmission period of the business datum of determining terminal, the present invention also provides three kinds of possible implementations, is elaborated below in conjunction with example 1 to example 3.
Example 1: access network elements is according to the historical specified data transmission time in transmission time of business datum.Because the historical transmission time can be reflected the Time-distribution of business data transmission, therefore, in this preferred embodiment, directly according to historical specified data transmission time in transmission time of business datum, its determine procedures is easy, determine reliable results.
Example 2: access network elements receives the transmission time distribution characteristics of the business datum of self terminal; Access network elements is according to the distribution characteristics specified data transmission time in transmission time.Because terminal can obtain the transmission time distribution characteristics of business datum in time, exactly, therefore access network elements is according to the distribution characteristics specified data transmission time in transmission time of coming self terminal, can guarantee that this data transmission period presses close to the situation of current terminal more, and then can guarantee the high efficiency of transmission of business datum between access network elements and terminal.
Example 3: access network elements receives the transmission time distribution characteristics from the business datum of core net; Access network elements is according to the distribution characteristics specified data transmission time in transmission time.Because core net can be stored the transmission time distribution characteristics of a plurality of business datums, therefore, access network elements is according to the distribution characteristics specified data transmission time in transmission time from core net, can guarantee to initiate the professional initial stage the user (namely not history of existence transmission time or transmission time in the past during distribution characteristics) with regard to the specified data transmission time, and then can guarantee the high efficiency of transmission of business datum between access network elements and terminal.
Need to prove that the mode in above-mentioned specified data transmission time only is several preferred implementations, in the practical application, any other can the specified data transmission time implementation, all should include protection scope of the present invention in.
Preferably, access network elements sends to SR resource and the entry-into-force time of configuration terminal and comprises: access network elements sends to terminal with SR resource and the entry-into-force time of configuration by the RRC dedicated signaling.
Consider outside the entry-into-force time, but may have interim essential data interaction between access network elements and the terminal.The embodiment of the invention provides a kind of possible solution alternately for upstream data, namely, in the time of outside terminal is in the entry-into-force time, access network elements receives Buffer Status Report (the Buffer State Report of the upstream data of terminal transmission, referred to as BSR), wherein BSR be used to indicate terminal under having upstream data to be sent and not existing for the situation of the Physical Uplink Shared Channel PUSCH resource that sends upstream data to access network elements application PUSCH resource; Access network elements is to terminal distribution PUSCH resource; Access network elements receives the upstream data of self terminal with the PUSCH resource, thereby can realize easy, reliably above-mentioned data interaction.
Preferably, with the SR resource of configuration with after the entry-into-force time sends to terminal, said method also comprises at access network elements:.
Preferably, at access network elements with the SR resource of configuration with after the entry-into-force time sends to terminal, said method also comprises: in the time of outside terminal is in the entry-into-force time, access network elements carries out reprovision to the SR resource, and wherein the cycle SR resource that is used to indicate after terminal still only is allowed to use reprovision in the entry-into-force time sends SR the SR resource of reprovision and entry-into-force time.
Preferably, the entry-into-force time comprise following one of at least: the biasing of the length of the entry-into-force time in the cycle of coming into force of entry-into-force time, the cycle of coming into force, the initial time of the entry-into-force time in the cycle of coming into force.
Be described in detail below in conjunction with the implementation procedure of instantiation to the embodiment of the invention.
The present embodiment scene is the LTE system, core network element is Mobility Management Entity (Mobility Management Entity, referred to as MME), access network elements is eNB, the log-on message of terminal is stored in local registrar (Home Subscriber Server is referred to as HSS).
Before introducing present embodiment, the part concept that need use present embodiment first (comprise preferred applicable situation of the present invention and at the data production of line service) is described.
Different types of service, whether the rule that the time interval that its packet arrives distributes is different, have periodically according to the data packet interarrival times, is broadly divided into periodic and aperiodic two classes.If have the time of advent of most of packets of business datum periodically, then adopt method of the present invention, can realize preferably effect, if be at random the time of advent of most of packets of business datum, not significantly not periodically, then advantage of the present invention will be difficult to fully, effectively bring into play.Therefore, when access network elements judges that the business datum of terminal does not have obvious periodicity, the entry-into-force time that can dispose for this user the SR resource, resource continuous the coming into force of SR that namely allows this terminal.
At present, the data that produce at line service roughly are divided into three following classes: (1), keep-alive message: for the link between the client and server that guarantees software, need the client software on the terminal periodically to send keep-alive message (Keep alive message) to server, its cycle usually at 30 seconds to a few minutes; (2), state upgrades: comprise the state variation promptings such as the reaching the standard grade of user self or good friend, stealthy, content update, these class data are non-periodic transfer, and its time interval is usually about several minutes; (3), the autonomous data that send of user: user's use habit is depended at the transmission interval of these class data usually, in busy, its data send interval at tens of seconds to tens minutes; In idle, its data send the interval may reach tens of minutes to more than one hour.
The below take present hot topic at line service as example, implementation procedure of the present invention is described in detail.
Steps A, for the data transmission period spaced features that obtains above-mentioned data (be whether transfer of data has periodically, the cycle size, average data Transmission Time Interval, the information such as mathematical distribution at data transmission period interval), eNB can be by three kinds of following modes:
(1), sends to eNB by terminal by RRC dedicated signaling (for example by RRCConnectionReconfigurationComplete message or RRCConnectionSetupComplete message, can with reference to 3Gpp agreement TS36.331);
(2), voluntarily the Transmission Time Interval feature of the business datum of terminal is added up to obtain by eNB;
(3), the data transmission period spaced features of miscellaneous service can be stored in (for example among the HSS) in the core network element, when the user initiates new business, sent to user's service eNB by the core net data transmission period spaced features that new business is corresponding.
Step B, eNB can decide how to be terminal configuration SR resource according to above-mentioned data transmission period spaced features, and whether to this SR resource distribution entry-into-force time.
In order more clearly to describe above-mentioned layoutprocedure, the present invention also provides an instantiation.
Suppose certain online chatting software that the user uses, eNB obtains its data transmission period spaced features and is: the keep-alive message transmission cycle is 30s; The average transmission time of state updating information is spaced apart 3 minutes; The user voluntarily average transmission time of the transmission of data is spaced apart 15 minutes.This shows that in the data that this user produces, major part is periodic keep-alive message, therefore be fit to adopt mechanism of the present invention, be this user and dispose SR resource and entry-into-force time thereof.
At first, eNB can determine cycle of this entry-into-force time in the following manner in this example:
User's SR resource distribution (referring to 3Gpp agreement TS36.331):
sr-PUCCH-ResourceIndex＝M；
sr-ConfigIndex＝1；
dsr-TransMax＝4；
In the above-mentioned parameter, sr-PUCCH-ResourceIndex represents the PUCCH resource index of user's SR, and the user can calculate to get the SR orthogonal code, cyclic shift and the frequency domain position on PUCCH that use according to this index.Computational methods define in TS36.211, do not belong to the present invention and innovate category, therefore are not described in detail in the present embodiment.
Sr-ConfigIndex represents the life cycle of the PUCCH resource index that described user's SR uses, the time domain sub-frame offset of PUCCH resource index that SR uses; In TS36.213, define, shine upon according to following table:
The mapping table of table 1sr-ConfigIndex, life cycle and time domain sub-frame offset
After dsr-TransMax represents that UE1 triggers SR, the number of times of the maximum transmission SR that allows (head that comprises SR passes and retransmits).
The content of above-mentioned SR resource distribution all defines in existing LTE agreement, does not belong to the present invention and innovates category, therefore is not described in detail in the present embodiment.
Here for simplicity, only enumerated the relevant configuration parameter of the Radio Resource that uses with SR in the prior art as an example, and do not enumerate the relevant configuration parameter of all SR in the prior art, in fact, according to content of the present invention, all configuration parameters relevant with SR all need to come into force according to the entry-into-force time of following SR resource distribution.
Therefore; eNB can be according to the greatest common divisor at the average arrival time interval of this user's keep-alive message and other two classes data in this example; the cycle of the entry-into-force time of the SR resource of configure user is 30 seconds, like this can be to greatest extent so that on the aperiodic data of other two classes also are complementary with the entry-into-force time.
Secondly, because the professional packet that produces of online chatting class usually less (its transmission is consuming time be generally less than 1 second), therefore, eNB can dispose the duration that comes into force of SR resource=1 second in this example.
Again, eNB can be in conjunction with the initial time of following formula 1 configuration take-effective duration in interim weekly biasing in this example.
Formula 1:
In the following formula, n
fExpression current system frame number (each system-frame length is 10ms), n
sThe sequence number (span be 0～19) of expression current time slots (slot, each slot length is 0.5ms) in radio frames (identical with system-frame length, as to be 10ms), N
SR_avail_offsetExpression comes into force the initial biasing moment in per cycle of duration, according to subframe (subframe, length is 1ms) be configured for unit, span is [0, (SR_avail_period-SR_avail_length) * 1000) (wherein SR_avail_length represents the duration that comes into force), SR_avail_period represents coming into force the cycle of SR resource distribution, because come into force cycle and come into force that duration all defines according to second, therefore multiply by 1000 in above-mentioned formula is converted into ms.
Network side and terminal be the above-mentioned formula of agreement in advance, and eNB only need define N
SR_avail_offsetGet final product, terminal can be according to N
SR_avail_offsetCalculate the initial biasing of per cycle of the described duration that comes into force constantly.
To sum up, according to SR resource and the entry-into-force time thereof of above-mentioned eNB configuration, the operable SR resource of user as shown in Figure 3, among Fig. 3, the vertical line square frame represents the SR resource distribution that eNB distributes to the user, and the SR resource distribution of other UE is distributed in the white box representative, can see, only in the duration that comes into force of entry-into-force time of the user's that eNB provides SR resource distribution, the SR resource distribution that the user just can use eNB to distribute; In the time of in not being in the duration that comes into force, user's SR resource distribution can be distributed to other UE by eNB and use.Simultaneously, because it is that data transmission characteristics with the user is complementary that eNB gives the entry-into-force time of user configured SR resource, the greatest common divisor interval at the average transmission interval of three kinds of data of the cycle of its entry-into-force time and user equates (namely 30 seconds), again because the data volume of online chatting business is less usually, therefore 1 second the duration that comes into force is enough to finish the transmission of a packet, therefore, the entry-into-force time of the SR resource of above-mentioned configuration can be so that the SR resource of system be fully utilized, and can not bring on the dispatch delay of UE obvious impact.
Fig. 4 is the schematic diagram according to the matching result of the entry-into-force time of the embodiment of the invention and user service data, and as shown in Figure 4, the entry-into-force time of periodic keep-alive message data and SR resource distribution mates fully; Although the aperiodic state more autonomous data that send of new data and user not have to mate fully with the entry-into-force time of SR resource distribution, major part can both be covered by the entry-into-force time, and unmatched probability of entry-into-force time is less.
Determining above-mentioned SR resource and after the entry-into-force time, eNB sends to the user with these information, it can send by the RRC dedicated signaling, and details is existing the definition in existing LTE agreement, is not described in detail.
In addition, determining above-mentioned SR resource and after the entry-into-force time, the transmission of the entry-into-force time of SR resource, can also be by in RRCConnectionReconfiguration or RRCConnectionReestablishment or RRCConnectionSetup message, increasing new cell (Information Element, referred to as IE) entry-into-force time of carrying SR resource and sending, perhaps by the direct entry-into-force time parameter of increase SR resource distribution in existing SR configuration IE.
In order more clearly to describe above-mentioned process of transmitting, the present invention also provides an instantiation.
Define a new IE:
Meaning of parameters among the above-mentioned IE is as follows:
Release represents the switch to the SR resource distribution entry-into-force time, if release puts 1, then represents the cancellation of SR resource distribution entry-into-force time (the SR resource distribution that is namely representing UE can continue to use, and is not subjected to the restriction of entry-into-force time).
Sr-Resource-Valid-Period represents coming into force the cycle of SR resource distribution, and span is 0～2047 second;
Sr-Resource-Valid-TimeLength represents the interior duration that comes into force of the cycle of coming into force of SR resource distribution, and span is 0～2047 second;
Sr-Resource-Valid-Offset represent to come into force duration the initial biasing of per cycle constantly, span is 0～2047000 millisecond;
Another example: above-mentioned parameter also can directly add among the existing IE:SchedulingRequestConfig.
After the user receives above-mentioned information, when terminal has SR to send, also comprised the entry-into-force time if both comprised the SR resource in this information, then this terminal only can send this SR according to this SR resource within the entry-into-force time of this SR resource; If only comprise the SR resource in this information, then this terminal can use this SR resource to send this SR all the time.
In addition, consider outside the entry-into-force time, but may have interim essential data interaction between access network elements and the terminal.Be described in detail below in conjunction with example.
In the time of outside UE is in the entry-into-force time, if eNB has the upstream data of this UE to arrive and etc. to be transmitted, eNB gets final product according to the flow process of current mechanism so, that is:
UE judges this moment whether available PUSCH resource is arranged, if do not have, then UE triggers random access procedure, reports the BSR of upstream data waiting for transmission to get final product to access network elements application PUSCH resource in random access procedure;
Outside the entry-into-force time of SR resource distribution, if access network elements is to user's SR resource distribution make amendment (reshuffling), then the SR resource distribution of the described UE behind the reprovision can not come into force at once, still only comes into force within the entry-into-force time of the SR of described UE resource distribution.
Need to prove, can in the computer system such as one group of computer executable instructions, carry out in the step shown in the flow chart of accompanying drawing, and, although there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
