Embodiment 1

[0038] Example 1, see figure 2 , taking the HSDPA system as an example to describe the scheduling strategy as the scheduling strategy of the maximum pilot signal quality index.

[0039] Step 201: Obtain the distribution of at least one HSDPA user in the planned area, that is, obtain specific location information of at least one HSDPA user in the planned area. Here, in the network simulation process, various possible distributions of HSDPA users can be input into the network simulation system to simulate various distribution conditions of HSDPA users that may appear in the actual environment. In this embodiment, the planned area is as image 3 As shown, two cells are included, and 10 HSDPA users (UE1~UE10) are distributed in this area. The specific location information of these 10 HSDPA users and the basic information of the two cells to be planned are input into the simulation system.

[0040] Step 202: Obtain the pilot channel quality of the HSDPA user according to the loc...

Embodiment 2

[0060] Example 2: see Figure 4 , taking the HSDPA system as an example to describe the scheduling strategy as a proportional fair scheduling strategy,

[0061] Step 401: Obtain the distribution of at least one HSDPA user in the planned area, that is, obtain specific location information of at least one HSDPA user in the planned area. At the same time, the network simulation system also obtains the basic information of each community in the planning area.

[0062] Step 402: Calculate the pilot channel quality of each HSDPA user in each cell according to the location of the user, and sort the HSDPA users in the same cell according to the calculated pilot channel quality.

[0063] Step 403: According to the sorting result of step 402, within the same TTI, select N HSDPA users with the best pilot channel quality for data transmission with a certain probability. That is, the selected N HSDPA users are N scheduled HSDPA users. Here, the HSDPA cell configuration determines that N...

Embodiment 3

[0068] Embodiment 3: see Figure 5 , taking the HSDPA system, the scheduling strategy is described as the round-robin scheduling strategy.

[0069] Step 501: Obtain the distribution of at least one HSDPA user in the planned area, that is, obtain specific location information of at least one HSDPA user in the planned area.

[0070] Step 502: Calculate the pilot channel quality of each HSDPA user according to the position of each HSDPA user in each cell. Here, it is only necessary to obtain the strongest pilot channel signal strength of the position where each HSDPA user is located. According to the strongest pilot channel signal Strength determines the cell where each HSDPA user is located.

[0071] Step 503: Randomly select N HSDPA users in the same TTI of each cell for data transmission. That is, the selected N HSDPA users are N scheduled HSDPA users.

[0072] Step 504: According to the location of each scheduled HSDPA user selected in step 503, the SINR of the location is...

Abstract

The invention discloses to a method for fetching high speed downlink packet access (HSDPA) transmission throughput, which is used for solving the problems that network simulation to a wireless networksystem after HSDPA technology is brought in is complex and the fetched HSDPA transmission throughput is inaccurate in the prior art. The method is that: Firstly, fetch pilot signal quality of each HSDPA user in at least one HSDPA user according to fetched location information of at least one high speed downlink packet access HSDPA user in a planning area, then select HSDPA users with set amount in each district as scheduling HSDPA users to transfer data according to the pilot signal quality of each HSDPA user by a set scheduling policy, finally, determine HSDPA transmission throughput in thedistrict according to the location information of each scheduling HSDPA user in each district. The invention also discloses a network simulation system for fetching HSDPA transmission throughput.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a system for obtaining high speed downlink packet access (HSDPA, High Speed ​​Downlink Packet Access) transmission throughput in network simulation. Background technique [0002] When planning a wireless network in a Code Division Multiple Access (CDMA, Code Division Multiple Access) system, considering the strong coupling between network coverage and network capacity caused by multiple access interference, it is necessary to plan the wireless network system Modeling, planning the capacity of the wireless network through simulation technology. Currently, wireless network planning software mostly adopts a static simulation method based on the theorem of large numbers for network simulation of capacity, and this simulation method has also been recognized by the industry. However, there is no mature method for the network simulation of the wirele...
