Description

Method, system and device for determining initial service authorization value

technical field

The present invention relates to mobile communication technology, in particular to a method, system and equipment for determining an initial Serving Grant (SG, Serving Grant) value.

Background technique

High Speed Uplink Packet Data Access (HSUPA, High Speed Uplink Packet Data Access) is a new technology introduced in the version 6 protocol of the third generation mobile communication standardization partnership project (3GPP, Third Generation Partnership Project) to increase the transmission rate of uplink data , using the uplink fast scheduling of the base station (NodeB), physical layer hybrid retransmission (HARQ, Hybrid Automatic Repeat request), soft handover and 2ms transmission time interval (TTI, Transmission Time Interval) short frame transmission technology, theoretically can support the highest The peak rate is 5.76Mbps.

Fig. 1 is the structural representation of HSUPA protocol in the existing Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system. As shown in Figure 1, on the user terminal (UE, User Equipment) side, a media access control (MAC, Media Access Control) layer entity MAC-es or MAC-e is added to implement HARQ retransmission and MAC-d Protocol data unit (PDU, Protocol Data Unit) multiplexing and other functions. MAC layer entities MAC-es and MAC-e are added on the network side. In order to support the fast scheduling of the base station, the MAC-e entity on the network side is moved down to the base station; in order to support the macro-diversity of HSUPA, the MAC-es is located in the Serving Radio Network Controller (SRNC, Server Radio Network Controller). An enhanced dedicated channel (E-DCH, Enhanced-Dedicated Channel) is added between the MAC layer and the physical layer (PHY, Physical Layer) to carry transmission data blocks.

Among them, several physical channels are added in the physical layer, for example, an enhanced dedicated physical control channel (E-DPCCH, E-DCH Dedicated Physical Control Channel) and an enhanced dedicated physical data channel (E-DPDCH) are added to the uplink physical channel. , E-DCH Dedicated Physical DataChannel). Correspondingly, an enhanced absolute grant channel (E-AGCH, E-DCH Absolute Grant Channel), an enhanced relative grant channel (E-RGCH, E-DCHRelative Grant Channel) and an enhanced acknowledgment indicator channel ( E-HICH, E-DCH HARQ Acknowledgment Indicator Channel). Among them, the uplink E-DPDCH is used to carry the uplink data transmitted by the UE in the HSUPA technology; the uplink E-DPCCH is used to carry the accompanying signaling of the demodulation data channel E-DPDCH. The downlink E-AGCH is a public channel, which is used to indicate the maximum available uplink transmission rate or power of the UE; the downlink E-RGCH is a dedicated channel, and the uplink transmission rate of the UE can be quickly adjusted at a frequency of 2ms at the fastest; the downlink E-HICH is The dedicated channel is used to send acknowledgment/non-acknowledgment (ACK/NACK, Acknowledgment/NegativeAcknowledgment) information to feedback whether the user receives process data correctly.

When the UE accesses the base station, the base station will configure the initial service grant (SG, ServingGrant) for the UE, and it will be carried by the radio network controller (RNC, Radio Network Controller) through the third layer (L3, Layer 3) signaling The Serving Grant Value (Serving Grant Value) is notified to the UE, and the value of the initial SG value directly determines the power ratio of the E-DPDCH and DPCCH that the UE can use when transmitting data. Subsequently, when the UE needs to perform service transmission, it can transmit data according to the initial SG value carried in the Serving Grant Value. During service transmission, UE can update the value of SG according to the absolute grant (AG, Absolute Grant) or relative grant (RG, Relative Grant) information received from E-AGCH or E-RGCH channel. Usually, the value of SG includes 38 levels ranging from 0 to 37. When the base station needs to increase or decrease the SG value of the UE by one level, it can update the SG on the UE side through the RG UP or RG DOWN authorization information; if it needs to increase or decrease multiple levels, it can directly update the UE through the AG information side of the SG.

In practical applications, ping delay is an important indicator for operators to examine network performance, and it can directly reflect whether the network can respond to UE requests in a timely manner. Usually, the shorter the delay, the better, provided that other performances are not affected.

When using HSUPA technology for data transmission, the initial SG value of the UE will directly determine the rate that the UE can use when it starts data transmission. If this value is set to a small value, even if the current network resources are sufficient, the UE must A higher transmission rate cannot be obtained until the base station allocates an AG or performs RG UP authorization for it. Before this, data transmission can only be performed at a lower rate, resulting in the inability of its own data to be transmitted in time, that is, the delay performance is greatly affected. Therefore, to address this problem, it is necessary to find a method capable of improving UE access delay.

In the prior art, during the process of UE accessing the network and performing wireless link establishment/addition/reconfiguration (PLSetup/Addition/Reconfigure), the base station can inform the wireless network through the information element "Serving Grant Value" in the relevant response message The initial SG value assigned by the controller to the UE; then, the radio network controller notifies the UE through L3 signaling. Table 1 shows the structure of the Serving GrantValue cell specified in the protocol.

Cell Name (IE/Group Name) Presentation (Presence) Range Cell type (IE Type and Reference) Description (Semantics Description) Serving Grant Value O (optional) INTEGER(0..37, 38) (0..37) indicates E-DCH serving grant index as defined in[32]; index 38 means zero grant

Table 1 The structure of the Serving Grant Value cell

Among them, 0-37 represent the possible values of SG, and 38 is a special value, which has nothing to do with the present invention and will not be introduced.

In the prior art, the setting mode of the initial SG value includes two kinds, the mode that is about to set the initial SG value to 0 and the mode of setting the initial SG value according to guaranteed bit rate (GBR, MAC-es Guaranteed Bit Rate), that is, by wireless The network controller notifies the base station of the corresponding GBR value of the UE, and the base station determines the initial SG value of the UE according to the GBR value. The characteristics of these two methods determine that it is impossible to fundamentally solve the problem of UE access delay, because:

If the initial SG value is set to 0, then only when the subsequent UE periodically reports scheduling information (SI, Schedule Information), that is, when the base station is notified of how much data it needs to send, the base station will allocate an AG grant to the UE so that the UE can start for data transfer. If the initial SG value is set according to GBR, although the delay can be reduced to a certain extent compared with the case where the initial SG value is set to 0, GBR is only the minimum transmission rate that the base station needs to allocate to the UE. Normally, according to this The initial SG value determined by the method is very small. When the SG value needs to be increased, the subsequent AG or RG authorization is required to increase the speed.

It can be seen that the initial SG value of the SG setting method in the prior art is set to be small, and the access delay when the UE transmits data to the network side is also relatively large.

Detailed ways

Aiming at the problems existing in the prior art, the embodiment of the present invention proposes a solution that can solve the UE access delay, including: determining the maximum allowed SG value according to the current remaining air interface resources; according to the current CE resource configuration and the service characteristics of the UE, combined with the obtained maximum allowed SG value, determine the initial SG value.

Compared with the prior art, in the solution described in the embodiment of the present invention, the initial SG value is determined according to the current remaining air interface resources and other information, and sent to the UE; subsequent UEs can perform data transmission according to the received initial SG value. Since the initial SG value determined according to the solution described in the embodiment of the present invention is usually relatively large (in the case of sufficient network resources), the UE access delay caused by the small initial SG value setting in the prior art is reduced question.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

Fig. 2 is a flowchart of a method embodiment of the present invention. In this embodiment, the determination of the initial SG value can be completed by the base station. As shown in Figure 2, the method may include:

S201: Determine the maximum allowed SG value according to the current remaining air interface resources.

In this step, the base station determines the maximum allowable SG value according to the current remaining air interface resources. The specific implementation method may be: the base station obtains the DPCCH signal-to-noise ratio (SIR, Signal toInterference Ratio) corresponding to the UE, the UE's serving cell (CELL) The remaining load factor α, the E-DPCCH gain factor β _ec and the DPCCH gain factor β _c . Since one base station may correspond to multiple cells, and different cells are responsible for providing services for different UEs, so in this step, the remaining load factor α obtained by the base station is the remaining load factor α of the serving cell where the UE is located. The load factor in this embodiment refers to a parameter used to indicate the severity of the uplink load, and the remaining load factor is the difference between the target load factor of the serving cell where the UE is located and the current actual load factor.

In practical applications, the values of DPCCH SIR, residual load factors α, β _ec and β _c can all be obtained through existing technologies. The specific acquisition process is well known in the art and will not be repeated here.

After obtaining the values of the above parameters, the base station calculates the unquantized maximum allowable SG value according to formula (1);

${<span\; class="notranslate">\; (</span>\frac{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; ed</span>}}}{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 256</span>}}{{\mathrm{<span\; class="notranslate">\; SIR</span>}}_{\mathrm{<span\; class="notranslate">\; DPCCH</span>}}}<span\; class="notranslate">\; *</span><span\; class="notranslate">\; (</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&alpha;</span>}}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>\frac{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; ec</span>}}}{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span>$

即为未量化的最大允许的SG值。本实施例中，之所以按照公式(1)的方式对未量化的最大允许的SG值进行计算，是因为现有技术中，剩余负载因子α可按照公式(2)计算：Among them, β _ed represents the gain factor of E-DPDCH;

That is, the unquantified maximum allowable SG value. In this embodiment, the reason why the unquantified maximum allowable SG value is calculated according to the formula (1) is because in the prior art, the residual load factor α can be calculated according to the formula (2):

$\mathrm{<span\; class="notranslate">\; \&alpha;</span>}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}{{\mathrm{<span\; class="notranslate">\; N</span>}}_{\mathrm{<span\; class="notranslate">\; o</span>}}}<span\; class="notranslate">\; /</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; +</span>\frac{{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}{{\mathrm{<span\; class="notranslate">\; N</span>}}_{\mathrm{<span\; class="notranslate">\; o</span>}}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; )</span>$

为每比特能量与噪声功率密度的比值，其具体计算方式如公式(3)所示：in,

$\frac{{\mathrm{<span\; class="notranslate">\; E.</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}{{\mathrm{<span\; class="notranslate">\; N</span>}}_{\mathrm{<span\; class="notranslate">\; o</span>}}}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; SIR</span>}}_{\mathrm{<span\; class="notranslate">\; DPCCH</span>}}}{\mathrm{<span\; class="notranslate">\; 256</span>}}<span\; class="notranslate">\; \&times;</span><span\; class="notranslate">\; [</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>\frac{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; ec</span>}}}{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>\frac{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; ed</span>}}}{{\mathrm{<span\; class="notranslate">\; \&beta;</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; ]</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; )</span>$

Substituting formula (2) into formula (3), formula (1) can be derived.

为未进行量化的最大允许的SG值，而基站向UE发送的SG值为量化后的值，所以本步骤中，基站还需要根据服务授权表(SG Table)对 进行量化，将 

向下量化到SG Table中一个与该 

最接近的量化值SGbyLoad，即最大允许的SG值。Since the calculated

is the maximum allowed SG value without quantization, and the SG value sent by the base station to the UE is a quantized value, so in this step, the base station also needs to To quantify, the

Quantize down to one in the SG Table with the

The closest quantization value SGbyLoad, that is, the maximum allowed SG value.

The SG Table usually includes 38 quantized values, that is, 0 to 37. Different quantized values correspond to unquantized values in different ranges. For example, in increasing order, unquantized values between 0 and A correspond to The quantized value of is 0, and the quantized value corresponding to the unquantized value between A～B (B>A) is 1. The specific quantization method is well known in the art and will not be repeated here. In this step, the base station will calculate the obtained Quantized to a value from 0 to 37, represented by SGbyLoad.

S202: Determine an initial SG value according to the current CE resource configuration situation and the service characteristics of the UE, combined with the obtained maximum allowed SG value.

In this step, the base station determines the initial SG value that needs to be sent to the UE according to the current CE resource configuration situation and the service characteristics of the UE, combined with the maximum allowed SG value obtained in S201. The specific implementation method may be:

The base station calculates the SG value SGbyCE corresponding to the CE value according to the CE value actually allocated to the UE by itself. The base station includes a CE scheduling entity, and the CE scheduling entity can calculate the SG value SGbyCE corresponding to the CE value according to the CE value actually allocated by the base station to the UE. Wherein, CE is a kind of resource that needs to be used when the base station demodulates the data reported by the UE. The base station determines the CE value allocated to the UE according to its own situation, such as how many CE resources can be allocated and how many UEs need to be allocated, and calculates the corresponding SGbyCE according to the CE value. The specific distribution method and calculation method are well known in the art and will not be repeated here.

In addition, in the HSUPA technology, when the UE accesses the network, the radio network controller will configure the maximum bit rate (MBR, E -DCH Maximum Bitrate) and GBR, and notify the base station through the base station application part (NBAP, NodeB Application Part) message. Among them, the radio network controller configures MBR and GBR for the UE according to the characteristics of the service itself carried out by the UE, such as the requirements of QoS (Quality of Service). Different service characteristics can correspond to different MBR and GBR values. The specific configuration method for existing technology. The radio network controller limits the maximum transmission rate that the UE can use by configuring the values of MBR and GBR, and requires the network side to provide a guaranteed bit rate as much as possible, that is, the minimum transmission rate that the network side needs to provide to the UE. Table 2 and Table 3 show the composition structure of MBR and GBR cells respectively.

Table 2 MBR Cell Composition Structure

IE/Group Name Prese nce Range IE type and reference Semantics description MAC-es Guaranteed Bit Rate INTEGER (0..2^24-1,...) Unit: bit/s

Table 3 GBR Cell Composition Structure

The MBR cell composition structure and the GBR cell composition structure shown in Table 2 and Table 3 are the formats specified in the existing protocol, and will not be repeated here.

After receiving the MBR and GBR from the radio network controller, the base station calculates the SG values SGbyMBR and SGbyGBR corresponding to the MBR and GBR respectively. The calculation method is the prior art, and will not be repeated here.

So far, the base station has obtained SGbyCE, SGbyMBR, and SGbyGBR, and can combine the SGbyLoad obtained in S201 to determine the initial SG value: due to the limitation of the current network resource configuration and the service characteristics of the UE itself, for example, the SGbyLoad calculated in S201 cannot be greater than The SGbyMBR configured for the UE cannot be smaller than the SGbyGBR configured for the UE; moreover, the SGbyLoad needs to be smaller than the SGbyCE, in case the CE resources cannot meet the requirements, etc.; the SGbyLoad calculated in S201 cannot be directly sent to the UE as the initial SG value, The initial SG value needs to be determined according to SGbyCE, SGbyMBR and SGbyGBR. The specific determination method can be performed as shown in formula (4):

SG=MAX(MIN(SGbyLoad, SGbyCE, SGbyMBR), SGbyGBR)

(4)

That is, take the minimum value among the three values of SGbyLoad, SGbyCE, and SGbyMBR, because these three values are the upper limit values that cannot be exceeded, so you can only take the smallest one of the three; then, compare the obtained minimum value with SGbyGBR For comparison, the larger value is taken. Since SGbyGBR is the lower limit value, the larger value between the obtained minimum value and SGbyGBR is determined as the initial SG value.

It can be seen that by adopting the technical solution of the embodiment of the present invention, the base station determines the initial SG value according to the current remaining air interface resources and other information, and sends it to the UE; subsequent UEs can perform data transmission according to the received initial SG value. Since the initial SG value determined according to the solution described in the embodiment of the present invention is usually relatively large, the problem of UE access delay caused by setting a small initial SG value in the prior art is reduced.

It should be noted that the embodiment shown in FIG. 2 is only used for illustration, and is not used to limit the technical solution of the present invention. For example, the process of acquiring SGbyCE, SGbyMBR, and SGbyGBR mentioned in S202 does not necessarily have to be performed after S201, and it is also possible to be performed before it. As long as the base station can finally obtain the four values of SGbyLoad, SGbyCE, SGbyMBR, and SGbyGBR.

The UE302 is configured to receive the initial SG value from the base station 301.

For the specific work flow of the system and device embodiments shown in FIG. 3 and FIG. 4 , reference may be made to relevant descriptions in the method embodiments, and details are not repeated here.

It can be seen that, by adopting the technical solution of the embodiment of the present invention, the initial SG value is determined according to the current remaining air interface resources and other information, and sent to the UE; subsequent UEs can perform data transmission according to the received initial SG value. When the network resources are relatively sufficient, the initial SG value determined according to the solution described in this embodiment is usually relatively large, thereby solving the problem in the prior art caused by setting the initial SG value small regardless of whether the network resources are sufficient or not. The problem of access delay when UE transmits data to the network side. A specific example is used below to further illustrate the technical effect of the solution described in the embodiment of the present invention.

When a UE with a category (category) of 3 pings a message with a size of 1460 bytes (byte), when resources are not limited, only one TTI (10ms) is needed to complete sending the message. However, if the method of setting the initial SG value to 0 in the prior art is adopted, it takes about 40 ms from when the UE sends the SI information to when the SG authorization issued by the network side takes effect. However, after adopting the technical solution of the embodiment of the present invention, the UE can directly use the maximum transmission rate supported by the network side when initially performing data transmission, thereby saving 40 ms of response time, that is, delay time.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
