Description

A kind of radio open resource PRB load evaluation method and device

Technical field

The present invention relates to the load evaluation technology in mobile communication, particularly relate to a kind of radio open resource Physical Resource Block (PRB, Physical Resource Block) load evaluation method and device.

Background technology

Effective utilization of Radio Resource is one of subject matter of facing of wireless network, and Optimizing Network Resources utilance makes the traffic carrying capacity intelligent distribution of the whole network, thus guarantees that the service quality of different business needs the problem of solution at present badly.But along with the development of Long Term Evolution (LTE, Long Term Evolution) network, LTE user gets more and more, the PRB resource overload that causes that Radio Resource is rare, eat dishes without rice or wine in LTE community.When PRB resource overload is eated dishes without rice or wine in community, need the partial service of LTE community to be diverted to second generation mobile communication technology (2G, Second Generation) community, third generation mobile communication technology (3G, Third Generation) community or LTE adjacent area.So, rationally accurately evaluate the eat dishes without rice or wine situation of PRB resource load of LTE community and become the problem that load balancing primarily solves.

According to third generation partner program (3GPP, The3rd Generation Partnership Project) transport stream (TS, Transport Stream) 36.300, the object of load balancing is the unbalanced distribution of the business load in order to solve community and minizone, reach Radio Resource high usage by affecting load Distribution, service quality (QoS, Quality of Service) ensures and low cutting off rate.Meanwhile, 3GPP has carried out simply defining to PRB USAGE in TS36.3144.1.1.1 joint and 4.1.1.2 joint:

TS36.3144.1.1.1 chapters and sections define the computational methods of Total PRB usage, the method based on reference point be the Service Access Point of medium access control (MAC, Medium Access Control) layer and physical layer, computing formula is as follows:

Wherein, the implication of each parameter in formula (1) is see table 1.

Table 1

TS36.3144.1.1.2 saves the PRB that chapters and sections define every levels of quality of service mark (QCI, QoS ClassIdentifier) and uses the computational methods of number, the method based on reference point be the Service Access Point of MAC layer and physical layer, computing formula is as follows:

$M1=(\mathrm{qci},T)=\underset{\∀t}{\mathrm{\Σ}}\underset{\∀p\∈S\left(t\right)}{\mathrm{\Σ}}\frac{1}{W\left(p\right)}\×X\left(t\right)\×\frac{B(t,\mathrm{pci})}{B\left(t\right)}---\left(2\right)$

Wherein, the implication of each parameter in formula (2) and formula (3) is see table 2.

Table 2

The PRB of existing 3GPP36.3144.1.1.1 and 4.1.1.2 joint uses the computational methods of number just to add up the instream factor of PRB, and PRB instream factor can not reflect the busy of network, therefore cannot evaluate PRB load accurately, more can not be directly used in the assessment of load.

Embodiment

In order to more at large understand feature of the present invention and technology contents, below in conjunction with accompanying drawing, realization of the present invention is described in detail, the use of appended accompanying drawing explanation only for reference, is not used for limiting the present invention.

Fig. 1 is the schematic flow sheet of the radio open resource PRB load evaluation method of the embodiment of the present invention, as shown in Figure 1, in a preferred embodiment of the invention, described radio open resource PRB load evaluation method assesses all carryings based in the unit interval, and this example wireless interface-free resources PRB load evaluation method comprises the following steps:

Step 101: measure non-VoIMS GBR based on MAC layer and carry PRB use number corresponding to unit throughput, carry PRB corresponding to unit throughput according to described non-VoIMS GBR and use number and GBR total value and first rate Dynamic gene, calculate the PRB load that described non-VoIMS GBR carries.

In the embodiment of the present invention, based on MAC layer, namely based on reference point, to be MAC layer with the Service Access Point of physical layer measure that non-VoIMS GBR carries PRB corresponding to unit throughput uses number; Here, non-VoIMS GBR carrying is the wherein a kind of of service bearer to be measured, and service bearer to be measured also comprises: non-GBR carrying, VOIMS carrying and common signal channel carrying.

Particularly, non-VoIMS GBR carrying belongs to the carrying of GBR traffic, carries, such as QCI=2 ~ 4 for all non-VoIMS GBR, and total PRB of the total throughout that all non-VoIMS GBR in measurement unit's time carry and correspondence uses number; And non-VoIMSGBR carries PRB use number corresponding to unit throughput according to following formulae discovery:

S1=M1÷N1 （4）

Wherein, described S1 is that described non-VoIMS GBR carries PRB use number corresponding to unit throughput; Described M1 is that described total PRB uses number; Described N1 is the total throughout that described non-VoIMS GBR carries.

So, the PRB use number of some non-VoIMS GBR carrying can be evaluated by said process.

Preferably, describedly carry PRB corresponding to unit throughput according to described non-VoIMS GBR and use number and GBR total value and first rate Dynamic gene, calculate the PRB load that described GBR carries, comprising: the PRB load of GBR carrying according to following formulae discovery:

P1=S1×G1×V1 （5）

Wherein, described P1 is the PRB load that described GBR carries; Described S1 is that described non-VoIMSGBR carries PRB use number corresponding to unit throughput; Described G1 is described GBR total value; Described V1 is described first rate Dynamic gene.

GBR total value in the present embodiment is the speed summation that all GBR carry, the speed of GBR carrying must ensure the normal transmission of GBR carrying, the total value parameter of GBR is by the strategy of core-network side and charging rule functions unit (PCRF, Policy and Charging Rules Function) configuration, and by mobile management entity (MME in loading establishing process, Mobility Management Entity) by message---S1APE-RAB SETUP REQUEST sends base station (eNodeB) to, and GBR total value is the speed of operation layer.

But, owing to being that to be MAC layer with the Service Access Point of physical layer measure that non-VoIMS GBR carries PRB corresponding to unit throughput uses number based on reference point at the present embodiment, therefore, GBR total value needs to be multiplied by first rate Dynamic gene, to match with described reference point.

As shown in Figure 3, packet is from PDCP (PDCP, Packet Data ConvergenceProtocol) layer needs through processes such as the compression of IP head, the encapsulation of PDCP layer, the encapsulation of wireless spread-spectrum technology (RLC, Radio Link Control) layer, MAC layer encapsulation to MAC layer.Operation layer packet, namely the IP packet of operation layer is the Service Data Unit (SDU of PDCP layer, Service Data Unit), therefore, the throughput that PRB load is measured in MAC layer is different from the GBR total value of operation layer, the packet header expense corresponding mainly due to PDCP layer, rlc layer, MAC layer and the huge Header compression (RoHC of PDCP layer, RobustHeader Compression), but PDCP RoHC compressed IP packet header is greater than packet header expense corresponding to PDCP layer, rlc layer, MAC layer for the impact of speed.

Therefore, the described first rate factor meets following formula:

V1=（R11-R12+R13+R14+R15）÷R11 （6）

Wherein, described V1 is the described first rate factor; Described R11 is the PDCP SDU speed that non-VoIMS GBR carries; Described R12 is the speed that the IP Header compression of non-VoIMS GBR carrying is corresponding; Described R13 is speed corresponding to PDCP packet header that non-VoIMS GBR carries; Described R14 is speed corresponding to RLC packet header that non-VoIMS GBR carries; Described R15 is the MAC packet header corresponding speed that non-VoIMS GBR carries.

In the embodiment of the present invention, based on MAC layer, namely based on reference point, to be MAC layer with the Service Access Point of physical layer measure that non-GBR carries PRB corresponding to unit throughput uses number.

Particularly, carry, such as QCI=5 ~ 8 for all non-GBR, all total throughouts of non-GBR carrying in measurement unit's time and total PRB of correspondence use number; And non-GBR carries PRB use number corresponding to unit throughput according to following formulae discovery:

S2=M2÷N2 （7）

Wherein, described S2 is that described non-GBR carries PRB use number corresponding to unit throughput; Described M2 is that described total PRB uses number; Described N2 is the total throughout that described non-GBR carries.

But, owing to being that to be MAC layer with the Service Access Point of physical layer measure that non-GBR carries PRB corresponding to unit throughput uses number based on reference point at the present embodiment, therefore, minimum non-GBR bit rate needs to be multiplied by the second speed Dynamic gene, to match with described reference point.

As shown in Figure 3, packet needs from PDCP layer to MAC layer through processes such as the compression of IP head, the encapsulation of PDCP layer, rlc layer encapsulation, MAC layer encapsulation.Operation layer packet, namely the IP packet of operation layer is the SDU of PDCP layer, therefore, the throughput that PRB load is measured in MAC layer is different from the GBR total value of operation layer, the packet header expense corresponding mainly due to PDCP layer, rlc layer, MAC layer and the RoHC of PDCP layer, but PDCP RoHC compressed IP packet header is greater than packet header expense corresponding to PDCP layer, rlc layer, MAC layer for the impact of speed.

Therefore, described second rate factor meets following formula:

V2=（R21-R22+R23+R24+R25）÷R21 （9）

Wherein, described V2 is described second rate factor; Described R21 is the PDCPSDU speed of non-GBR carrying; Described R22 is the speed that the IP Header compression of non-GBR carrying is corresponding; Described R23 is the speed corresponding to PDCP packet header of non-GBR carrying; Described R24 is the speed corresponding to RLC packet header of non-GBR carrying; Described R25 is the MAC packet header corresponding speed of non-GBR carrying.

In the embodiment of the present invention, based on MAC layer, the Service Access Point being namely MAC layer and physical layer based on reference point is measured total PRB that VoIMS carries and is used number.

Particularly, carry, such as QCI=1 for all VoIMS, total PRB of the VoIMS carrying in measurement unit's time uses number to be P3, then the PRB load of VoIMS carrying is P3.

So, the PRB use number of some VoIMS carrying can be evaluated by said process.

Here, because the speed of VoIMS carrying is more stable, therefore, without the need to Dynamic gene of advancing the speed.
