Description

Method and device for optimizing wireless network access parameters

technical field

The invention relates to parameter optimization technology in the field of wireless communication, in particular to a method and device for optimizing wireless network access parameters.

Background technique

The data traffic of the GSM network is getting higher and higher, and among the huge data traffic, small-packet services (such as QQ, Fetion, WeChat, etc.) account for more than 50% of the total traffic. The small packet service has the characteristics of less single traffic, more access times, and low utilization of channel resources, which occupies a large amount of network resources and causes the utilization of wireless channel resources in the wireless network to skyrocket.

For the small packet business, a resource-optimized small packet detection technology is introduced for the small packet service. In order to detect the small packet, the GSSN (Serving GPRS SUPPORT NODE) network element in the network detects the data volume of the small packet, and establishes the TBF according to the data volume allocation. The required number of PDCH channels can effectively reduce the radio resources occupied by TBF. For example, Ericsson's ACTIVE TBFLIMIT only considers TBFs with data bearers, not all TBFs, when calculating the multiplexing of a cell's Packet Data Channel (PDCH). The characteristic of the small packet service is that the TBF has no data bearer most of the time during use. Therefore, after activating this function, the wireless network can use the same PDCH to carry more user small packet services, and the effective utilization of network resources is greatly improved.

The TBF is usually a communication connection for temporarily transmitting data established between a mobile station (Mobile Station, MS) and a base transceiver station (Base TransceiverStation, BTS). After the TBF is established, different TBFs need to be distinguished by the TBF indication. In the same PSET of GSM network communication, TBF indication resources are limited. The uplink TBF indication resource (Uplink StateFlag, USF) usually includes 3 bits, which can realize the indication of 8 different TBFs; the downlink TBF indication resource (Temporary FlowIndicator, TFI) usually includes 5 bits , can realize the instruction to 32 TBF. When the TBF in the same PSET has not reached the upper limit, but the TBF indicates that the resources are exhausted, the establishment of the TBF cannot be completed and the data service access fails.

In the prior art, the small packet detection technology only considers the TBF, but ignores the lack of TBF indication resources, which will lead to the failure of TBF establishment.

Detailed ways

The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment one:

As shown in Figure 1, this implementation provides a method for optimizing wireless network access parameters, the method comprising:

Step S110: counting the success rate of TBF establishment;

Step S120: When it is determined that the TBF establishment success rate is lower than the first standard value, and the reason for the TBF establishment success rate is lower than the first standard value is that the TBF indicates insufficient resources, generate a first parameter adjustment instruction;

Step S130: According to the parameter adjustment instruction and the pre-stored first adjustment strategy, increase the total number of PESTs, increase the number of TBF indication resources included in a single PEST, shorten the blank TBF retention time, and/or reduce the number of PDCHs included in a single PEST, and At the same time, the total number of PESTs is increased inversely.

The specific operation of the step S110 may be that the network management device or the communication server extracts data related to TBF establishment from the BSC, and calculates the success rate of TBF establishment. In this embodiment, all parameters that can affect the terminal's access to the network can be regarded as wireless network access parameters.

The step S120 can be divided into multiple steps, specifically as shown in FIG. 2 :

Step S121: Judging whether the success rate of establishing the TBF is lower than the first standard value; if so, proceed to step S122: if not, directly end the procedure or transfer to other processing procedures;

Step S122: Determine whether the cause of the TBF establishment success rate lower than the first standard value is that the TBF indicates insufficient resources; if so, proceed to step S123: if not, directly end the process or transfer to other processing processes;

Step S123: Generate a first parameter adjustment instruction.

The first standard value in step S121 is a pre-stored threshold, and the threshold may be an empirical value obtained from historical data or an estimated value obtained through a simulation model based on current channel conditions and communication requirements. When the TBF establishment success rate is lower than the first standard value, it indicates that the TBF establishment failure rate is high at this time, and the access capability of the data service network is poor.

Reasons for the low success rate of TBF establishment include insufficient PDCH resources for establishing TBF, poor current radio channel quality resulting in unsuccessful establishment, and insufficient resources indicated by TBF. In step S122, whether the cause of the low success rate of TBF establishment is that the TBF indicates insufficient resources can be determined through methods such as elimination or sampling. The TBF indication resources include uplink TBF indication resources and downlink TBF indication resources; the uplink TBF indication resources are generally represented by USF; the downlink TBF indication resources are generally represented by TFI.

In step S123, when the TBF indicates insufficient resources, the network management device or the server or the base transceiver station generates a first parameter adjustment instruction.

The pre-stored first adjustment strategy described in step S130 may be an adjustment with a fixed step size or an adjustment according to a specified adjustment function. There are many specific implementation methods, which will not be listed here. The fixed step adjustment is based on a known step value, such as reducing the number of PDCH channels included in a single PEST by 2 each time or adding n PESTs each time, where n is an integer not less than 1. The adjustment function may be a coefficient function adjustment performed as an adjustment coefficient based on a ratio formed between the current TBF establishment failure rate and the TBF indication resource shortage rate, and the like.

The adjustment of the wireless network access parameters in step S130 includes at least the following types, one or more of which can be selected during the specific implementation process.

The first type: directly increase the number of TBF indication resources contained in each single PEST;

The second method: increase the total number of PESTs, thereby indirectly increasing the total number of TBF indication resources. In the case that the number of TBFs occupied by communication in the designated cell remains unchanged, it can also reduce the problem of TBF establishment failure caused by insufficient TBF indication resources. .

The third method: shorten the blank TBF retention time. After the TBF is established between the terminal and the base transceiver station, in order to realize one-time communication that can be used for multiple small packet services, the TBF will be released after a period of delay after the terminal and the base transceiver station have completed one communication. At this time, the TBF is an idle TBF, and the idle TBF also occupies the TBF indication resource. In this embodiment, in order to speed up the release of the TBF indication resource, the retention time of the blank TBF may be shortened, so as to effectively improve the effective utilization rate of the TBF indication resource.

The fourth type: reduce the number of PDCH channels included in a single PSET, and increase the total number of PSETs inversely proportional to the reduction factor of the number of PDCH channels included in a single PSET. Usually a PSET includes multiple PDCH channels; the PDCH channel is the smallest unit that bears TBF. The more the number of a PDCH channel is, the more the number of TBFs is carried. In the case of limited TBF indication resources, reducing the corresponding PDCH channels in a single PSET can avoid the problem of TBF establishment failure caused by the lack of TBF indication resources in a single PSET. And inversely increasing the PSET can avoid the problem of TBF establishment failure due to the decrease in the number of PDCH channels caused by the decrease in the total number of PSETs. Therefore, in S150 of this embodiment, the success of TBF establishment can be solved by reducing the number of PDCH channels included in a PSET and increasing the total number of PSETs inversely. reason for the low rate.

Specifically, if the number of PDCH channels included in a single PSET is halved, the total number of PSETs will be doubled, which is equivalent to dividing a larger PSET into multiple smaller PSETs, which not only solves the problem of TBF establishment failure due to insufficient resources indicated by TBF , while ensuring that there are still enough PDCH channels for communication between the terminal and the base transceiver station.

In the wireless network access parameter optimization method described in this embodiment, for the problem that the success rate of TBF establishment is lower than the first standard value caused by insufficient TBF indication resources, the PDCH channel included in a PSET, the total number of PSETs, and the TBF indication resources are carried out. And the optimization of at least one parameter in the blank TBF retention time can effectively improve the network access capability, especially the network access capability of the data service.

The network parameter optimization method described in this embodiment is especially suitable for improving the performance of data service access, especially when combined with the small packet detection technology, the improvement of data service access performance is more obvious.

As a further improvement of this embodiment,

As shown in Figure 3, the method also includes:

Step S210: Count the success rate of PDCH allocation;

Step S220: judging whether the PDCH allocation success rate is lower than a second standard value;

If not, then enter step S230; if yes, then enter the processing flow of the specified cell for capacity expansion and/or business offload; wherein, any of the existing methods can be used for capacity expansion and/or service offload, in this embodiment Step S280 and step S290 provide a preferred way;

Step S230: the statistical TBF establishment success rate;

Step S240: Determine whether the success rate of TBF establishment is lower than the first standard value; if so, proceed to step S250:

Step S250: generating a first parameter adjustment instruction;

Step S260: According to the parameter adjustment instruction and the pre-stored first adjustment strategy, increase the total number of PESTs, increase the number of TBF indication resources included in a single PEST, shorten the blank TBF retention time, and/or reduce the number of PDCHs included in a single PEST, and At the same time, the total number of PESTs will be increased inversely;

Step S280: generating a second parameter adjustment instruction;

Step S290: According to the second parameter adjustment instruction and the pre-stored second adjustment strategy, perform at least one of increasing the half-rate threshold and lowering the cell reselection hysteresis CRH.

Increasing the half-rate threshold is equivalent to reducing the full-rate PDCH channels, so that one PDCH channel can carry more service data, which can effectively alleviate the problem of wireless network access failure caused by insufficient PDCH channel resources.

Specifically how to increase the half-rate threshold can use the following methods:

Use the counter COUNTTER-NP to count PDCH channel resource shortage events;

Determine the half-rate threshold according to HRLIM+COUNTTER-NP*a; wherein a is a half-rate threshold adjustment parameter; in this embodiment, it is preferably 0.1, and the specific value range can be determined according to the wireless environment and communication requirements of the current cell. Wherein, the HRLIM is the current half-rate threshold of the current cell.

By lowering the CRH, even if the cell is at the edge of the two cells, the source cell can be cut into the target cell faster, so that the traffic of the source cell can be diverted to the target cell, and it can also reduce the PDCH channel resource shortage in the source cell. The problem of poor wireless network access performance.

Specifically, how to down-regulate CRH can be achieved by the following steps:

Use the counter COUNTTER-NP to count PDCH channel resource step events;

According to CRH-COUNTTER-NP*b; wherein, the CRH is the current cell reselection hysteresis; the b is a CRH adjustment parameter, the value is preferably 2 in this embodiment, and the specific value can be based on the wireless status of the cell and communication needs.

In a specific implementation process, the statistics of the PDCH allocation success rate and the TBF establishment success rate may also be performed simultaneously. If the PDCH allocation success rate is 100%, it means that the PDCH channel resources in the cell where the terminal is located or in the designated cell are sufficient at this time, and the reason for the TBF establishment failure has nothing to do with insufficient PDCH channel resources. If the PDCH allocation success rate is higher than the second standard value; the second standard value is generally not greater than 100%, which means that the PDCH channel resources are relatively sufficient at this time, and have little influence on whether the TBF establishment is successful. Therefore, when analyzing the reason why the TBF establishment success rate is lower than the first standard value, the cause analysis of the low PDCH allocation success rate is prioritized.

Both the first parameter adjustment instruction and the second parameter adjustment instruction in this embodiment may be adjustment-related control signaling including the parameter to be adjusted and the adjustment method, and the network management device or the server or the processor installed on the base station Formation; at the same time, it can also be a simple trigger signal, such as an electrical signal for parameter adjustment. As for how to adjust the parameters, which parameters are adjusted are stored in advance by the logical network element or physical network element performing the parameter adjustment.

As shown in FIG. 4, a specific application example is provided below based on the wireless network access parameter optimization method described in this embodiment:

Step S310: The SERVER program applied on the server or network management equipment extracts data from the BSC, and calculates the success rate of TBF establishment and PDCH allocation.

Step S320: Judging whether the data service accessibility is normal; the specific judging method includes: judging that the success rate of TBF establishment and the success rate of PDCH allocation are higher than their corresponding standard values,

If yes, it means that the data service access is normal at this time, and the data service with better communication effect in the designated cell can be guaranteed, and the wireless network access parameter optimization process can be ended.

Otherwise, it means that the data service accessibility in the designated cell is not normal at this time, and the process goes to step S320.

Step S330: If the PDCH allocation success rate is low (for example, lower than a pre-stored or received first threshold), it means that the PDCH channel resources are insufficient at this time and go to step 360; otherwise, go to step S340.

Step S340: When the success rate of TBF establishment is low (for example, lower than a pre-stored or received second threshold), and in the case of sufficient PDCH channel resources, it is determined that the TBF indicates insufficient resources, specifically including the determination of insufficient TFI and USF resources insufficient,

If the TBF indicates insufficient resources, then go to step S360, otherwise, end the network parameter optimization procedure or go to other processing procedures.

Step S350: Optimizing parameters, and the specific implementation scheme of optimizing parameters can be any one of the following:

Solution 1: reduce the number of PDCH channels included in a PSET and increase the number of PSETs inversely;

Solution 2: Increase the TBF indication resources included in PSETS;

Solution 3: Shorten the blank TBF retention time;

Solution 4: Increase the total number of PSETs in each wireless frame separately.

The parameters adjusted by the wireless network access parameter adjustment method described in this embodiment are used to achieve better access performance of the terminal's wireless access, and synchronize the statistics of the success rate of PDCH allocation and the parameters related to the PDCH channel The adjustment can effectively improve the success rate of data service network access.

A specific example based on step S350 is provided below. The SERVER program optimizes the data channel configuration, adjusts the parameter PSET, and changes PSETLIMIT=8 to PSETLIMIT=4, which means that a PSET is changed from including 8 PDCH channels to including 4 PDCH channels. At the same time, the total number of PSETs is doubled, so that the total number of TBF indication resources is doubled, and the total number of TBFs that can be established remains unchanged. At the same time, the blank TBF retention time can also be shortened, such as TIMER=TIMER-100=1600, so that the original TIMER=1700 time units can be changed to 1600 time units. The time unit can be microseconds or milliseconds.

By adjusting the number of time slots used to carry data services in each wireless frame, the adjustment of the number of PDCH channels can be adjusted; usually, a PSET can only exist on one carrier, and when the total number of PDCHs remains unchanged, reduce the number of PDCHs in a PSET Quantity, while will result in the total number of PSETs. The more time slots used to carry data services in a single radio frame, the more PDCH channels included in the PSET.

Based on the above, the wireless network access parameter optimization method described in this embodiment changes the problem of TBF establishment failure caused by the control of TBF indication resources in the existing method, and realizes network access through adjustment and optimization of parameters related to TBF indication. Enhanced access capabilities.
