Description

Access admission control method for high-speed downlink packet access service

technical field

The invention relates to the third-generation mobile communication technology, in particular to an access permission control method for high-speed downlink packet access services.

Background technique

As a hot spot in the development of the communication field in recent years, the third generation mobile communication (3rd Generation, referred to as "3G") has become the most concerned technology in the world, and it is the most important development direction in the first decade of the 21st century. According to the needs of the market and the development of technology, the International Telecommunication Union (International Telecommunication Union, referred to as "ITU") began to study 3G technology and standards since 1986, and successively established two international standardization organizations - 3G Cooperative Engineering Organization (3rdGeneration Partnership Project, referred to as "3GPP") and 3G Second Cooperative Engineering Organization (3rdGeneration Partnership Project 2, referred to as "3GPP2") to complete the detailed draft of the standard. By May 2000, the ITU officially determined three standards centered on Code Division Multiple Access ("CDMA") technology as the 3G global technical standard, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, "WCDMA" for short) technology is one of them, and 3GPP will continue to be responsible for its improvement.

The WCDMA follow-up standards formulated by 3GPP are currently divided into R99, R4, R5 and the latest R6 versions. The system framework diagrams of this series of versions are basically similar. Its main feature is the Universal Terrestrial Radio Access Network (TRAN), "UTRAN" for short) adopts WCDMA technology.

In 3GPP R99/R4, the processing capability of the system is described by the number of CE (Channel Element, "CE" for short). One CE can process one channel of voice. Using CE can convert different types of system processing capabilities such as voice and data into a unified scale, and quantify the processing capabilities into values that can be compared with the processing capabilities of other services. Therefore, the number of CEs can be used as The basis for license (access certificate) authorization. By using software licenses (access certificates) to control CE, operators can gradually purchase software licenses (access certificates) with the certificate).

For example, assume that a set of base station equipment can handle 256 channels, but the operator only needs 140 channels in the Phasel stage. The value of the equipment is divided into two parts: hardware and software. The software is controlled by the license (access card). In the first stage, only the license (access card) of 140 channels needs to be purchased; The operator needs to increase the number of channels to 200. At this time, he only needs to purchase a software license (access card) for 60 channels to meet the demand; after 4 years, the operator needs to increase the number of channels to 240. At this time, he only needs to purchase another 40 channels. The software license (access card) for each channel. In this way, the CE license can reduce the initial investment of the operator, and achieve a win-win situation for equipment manufacturers and operators.

One of the important features of the R5 version of WCDMA technology is HSDPA (High Speed Downlink Packet Access, referred to as "HSDPA"). The basic idea is to establish a high-speed shared transmission channel to increase the data transmission rate. The introduction of HSDPA technology makes the data transmitted at the Iub port increase the HSDPA data on the basis of the original dedicated channel data and public channel data. The transmission of data on Iub will occupy a certain transmission bandwidth. The Iub bandwidth occupied by the data of the dedicated channel and the public channel is fixedly allocated according to the business conditions transmitted on the channel. However, because the transmission channel of HSDPA is a shared channel, multiple user data are transmitted on the same channel.

However, because HSDPA is a shared channel, not a dedicated channel, the CE in 3GPPR99/R4 cannot be used to measure the processing requirements, that is, it is impossible to use CE to quantify the processing capability requirements of HSDPA services for communication equipment to be compatible with other services. The numerical value of the processing power comparison.

Contents of the invention

In view of this, the main purpose of the present invention is to provide an access admission control method for high-speed downlink packet access services, so that the processing capability of communication equipment for HSDPA services can be quantified into a value that can be compared with the processing capabilities of other services.

In order to achieve the above object, the present invention provides an access permission control method for a high-speed downlink packet access service, which is applied to a third-generation mobile communication system. When a user initiates a call, the method includes the following steps:

The network side calculates the number of equivalent channel units of the high-speed downlink packet access service according to the number of current high-speed downlink packet access connections in the cell, and adds the number of channel units occupied by other service units and/or the number of equivalent channel units to obtain The current total number of channel units in the cell;

Judging whether the total number of channel units is greater than a preset first threshold, if so, rejecting the call, otherwise continuing the call.

Wherein, when calculating the number of equivalent channel units of the high-speed downlink packet access service according to the current number of high-speed downlink packet access connections in the cell, it is calculated in a progressive system.

In addition, in the method, when performing the progressive calculation:

Presetting the second threshold and the third threshold, wherein the third threshold is greater than the second threshold;

For the part of the number of connections for high-speed downlink packet access that is greater than the third threshold, set the number of equivalent channel units for each connection to 2;

For the part of the number of connections for high-speed downlink packet access that is greater than the second threshold and less than or equal to the third threshold, set the number of equivalent channel units for each connection to 4;

For the part of the number of connections of the high-speed downlink packet access that is less than or equal to the second threshold, the number of equivalent channel units for each connection is set to be 8.

In addition, in the method, the values of the second and third thresholds are determined according to the following standards through pre-measurement or simulation:

When the number of high-speed downlink packet access connections in the cell is less than or equal to the second threshold, the average maximum transmission speed of the connected high-speed downlink packet access users should be greater than 384K bits per second;

When the number of high-speed downlink packet access connections in the cell is less than or equal to the third threshold, the average maximum transmission speed of the connected high-speed downlink packet access users should be greater than or equal to 128K bits per second.

In addition, in the method, the current total number of channel units in the cell may be the sum of the number of channel units and/or the number of equivalent channel units occupied by all calls of all service types in the cell.

In addition, in the method, the current total number of channel units in the cell may be the sum of the number of channel units and/or the number of equivalent channel units occupied by all calls of at least one pre-specified service type in the cell, which is determined in advance The specified service types include high-speed downlink packet access services.

Furthermore, the method is used to authorize the use of third generation mobile communication devices.

Also in the method, the channel unit may be a channel unit defined by the Third Generation Partnership Project R99.

By comparison, it can be found that the main difference between the technical solution of the present invention and the prior art is that the number of equivalent CEs of HSDPA services is calculated according to the current number of HSDPA connections in the cell, and the CEs and/or equivalent CEs occupied by other services are added. Get the current total number of CEs in the cell, and use the total number of CEs as the quantitative representation of the current processing capacity of the cell, and use it as the basis for rejecting new calls.

During specific implementation, a progressive system may be used to set several intervals of the number of HSDPA connections, and each interval is preset with a corresponding number of equivalent CEs for each connection.

The principle of interval setting is that each HSDPA user can obtain a certain transmission speed guarantee within this interval.

The difference in this technical solution has brought obvious beneficial effects, that is, the HSDPALicense (license) can be uniformly converted to the CE License of 3GPP R99. In this way, operators can achieve transparency and simplify maintenance of various wireless access technologies when managing base station licenses.

Because the number of equivalent CEs that can be converted for each HSDPA connection is fundamentally based on the transmission rate, and voice and other data services also have a certain transmission rate, so it can be naturally unified, and it is relatively easy to establish between operators and equipment Agreement among manufacturers.

By setting different equivalent CE numbers for each connection for different numbers of HSDPA connections, it can comply with the rule that the transmission speed of HSDPA users changes with the number of HSDPA connections, so that the license conversion is more accurate.

Description of drawings

FIG. 1 is a schematic flow chart of a method for controlling access permission of an HSDPA service according to an embodiment of the present invention.

Detailed ways

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 in conjunction with the accompanying drawings.

A method for controlling access permission of HSDPA services according to an embodiment of the present invention is shown in FIG. 1 . It should be pointed out that this method is applied to a 3G system, and more specifically, this method can be used to authorize the use of 3G equipment.

Referring to Fig. 3, at first in step 110, when the user initiates a call, according to the connection number of current HSDPA in the subdistrict, determine the equivalent CE number of HSDPA service of this subdistrict, wherein CE can be the CE defined by 3GPP R99.

The number of equivalent CEs that can be converted for each HSDPA connection is fundamentally based on the transmission rate, and voice and other data services can also be converted according to the transmission rate, so it can be naturally unified, and it is relatively easy for operators and equipment Agreement among manufacturers.

The number of HSDPA connections is the number of connections in the HSDPA state, but the rate that each HSDPA connection can carry is uncertain, and is related to the total number of users in the current cell, the number of HSDPA resources (power, code), and service models.

In this embodiment, the equivalent CE number is calculated using the progressive system, which can be calculated in the following way:

Two thresholds are preset—a second threshold and a third threshold, wherein the third threshold is greater than the second threshold. Of course, it can also be one or more thresholds, which can be set according to actual needs.

For the part of the number of HSDPA connections greater than the third threshold, the number of equivalent CEs for each connection is set to 2;

For the part of the number of HSDPA connections that is greater than the second threshold and less than or equal to the third threshold, the number of equivalent CEs for each connection is set to 4;

For the part of the number of HSDPA connections that is less than or equal to the second threshold, the number of equivalent CEs for each connection is set to be 8.

For example, assuming that the second threshold is 6 and the third threshold is 18,

If the current number of HSDPA connections is 5, each HSDPA connection is equivalent to 8 equivalent CEs, and the number of equivalent CEs of the HSDPA service in the cell is 5×8=40.

If the current number of HSDPA connections is 18, each HSDPA connection is equivalent to 8 equivalent CEs for the part less than or equal to 6, and each HSDPA connection is equivalent to 4 equivalent CEs for the part greater than 6 and less than or equal to 18. Therefore, the number of equivalent CEs of the HSDPA service in the cell is 6*8+(18-6)*4=96.

If the current number of HSDPA connections is 20, each HSDPA connection is equivalent to 8 CEs for the part less than or equal to 6, and is equivalent to 4 equivalent CEs for each HSDPA connection for the part greater than 6 and less than or equal to 18. In the part of 18, each HSDPA connection is equivalent to 2 equivalent CEs, so the number of equivalent CEs of the HSDPA service in the cell is 6×8+(18-6)×4+(20-18)×2=100.

In specific implementation, the currently valid HSDPA connections can be numbered from 1; each HSDPA connection numbered below 6 (including 6) is converted to 8 equivalent CEs; ) between each HSDPA connection is converted into 4 equivalent CEs; for each HSDPA connection numbered above 19 (including 19), it is converted into 2 equivalent CEs.

It can be seen that in this embodiment, the number of HSDPA connections is divided into several intervals for processing by using the second and third thresholds. The principle of setting the second and third thresholds is that each HSDPA user can obtain a certain amount of transmission in this interval. Speed guaranteed. In this embodiment, through pre-measurement or simulation, the values of the second and third thresholds are determined according to the following criteria:

When the number of HSDPA connections in the cell is less than or equal to the second threshold, the average maximum transmission speed of the connected HSDPA users should be greater than 384K bits per second. When the number of HSDPA connections in the cell is less than or equal to the third threshold, the average maximum transmission speed of the connected HSDPA users should be greater than or equal to 128K bits per second.

By setting different equivalent CE numbers for each connection for different HSDPA connection numbers, the present invention can comply with the law that the transmission speed of HSDPA users changes with the number of HSDPA connections, so that the license conversion is more accurate.

Thereafter, enter step 120, and calculate the current total number of CEs in the cell.

The current total number of CEs in a cell can be the sum of the number of CEs occupied by all calls of all service types in the cell and/or the number of equivalent CEs, or it can be the sum of the number of CEs occupied by all calls of at least one pre-specified service type in the cell The sum of CE numbers and/or equivalent CE numbers. "And/or" refers to the two possibilities of "and" and "or". Specifically, some services (such as voice services) are directly calculated by the number of CEs, while other services (such as data services) are calculated by equivalent It is calculated by the number of CEs. Therefore, when calculating the total number of CEs of various services, if the service is counted by CE, it is counted as the number of CEs, and if the service is counted by equivalent CEs, it is counted as the number of equivalent CEs.

In the present invention, regardless of whether the current total number of CEs in a cell is the sum of the number of CEs occupied by all calls of all service types and/or the number of equivalent CEs, or the number of CEs occupied by all calls of a pre-specified service type and/or Or the sum of the equivalent CE numbers, including HSDPA services.

In this step, the number of CEs equivalent to the HSDPA service and the number of CEs occupied by other services and/or the number of equivalent CEs are added together to obtain the current total number of CEs in the cell. The total number of CEs can be used as a quantitative representation of the currently used processing capability of the cell.

Thereafter, enter step 130, use the above-mentioned total number of CEs as the basis for rejecting new calls, specifically, judge whether the total number of CEs is greater than the preset first threshold, that is, the number of Licenses (permits) that the equipment manufacturer allows the operator to use. It includes the HSDPA License.

If it is determined in this step that the total number of CEs is greater than the preset first threshold, it means that the demand for equipment capabilities exceeds the equipment processing capabilities that the equipment manufacturer allows to the operator. In order to protect the interests of the equipment supplier, enter step 140 and reject the call. On the other hand, if it is determined that the total number of CEs is not greater than the preset first threshold, then enter step 150 and continue calling.

As can be seen, in the present invention, the HSDPA License (permit) can be uniformly converted to the CE License of 3GPP R99. In this way, operators can achieve transparency and simplify maintenance of various wireless access technologies when managing base station licenses.

Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the present invention. The spirit and scope of the invention.
