Problems solved by technology

[0003]The existing drive test work is mainly carried out manually. On the one hand, it needs to invest a lot of manpower and time, which brings a lot of cost to the operator's network construction and maintenance. The heavy burden increases the operation and maintenance cost of the network; on the other hand, this kind of road test can only obtain the measurement information of outdoor public areas, but cannot obtain the information of indoor and private areas, such as office buildings or residential buildings. There are often a large number of users, so the measurement information of these locations is actually more meaningful, but it cannot be obtained through the existing drive test methods, so it is difficult to complete the network optimization of these locations through drive tests
[0004] The current 3GPP RAN2 is conducting research and discussions on the minimization of the drive test project (WI), and proposed some measurement quantities of the LTE (Long Time Evolution, long-term evolution) system, but lacks the UMTS TDD system (such as TD-SCDMA system) Measurement
Since the current commercial communication system includes the TDD-SCDMA system of the TDD standard, how to provide the function of minimizing the drive test for the current TDD system is still blank.

example 1

[0052] Example 1: The network sets the UE in the cell to record the failure event of receiving the PCCH channel (that is, decoding the PCH), and the receiving UE performs the PCCH optimization process according to the failure event information reported by the indication. The process is described by taking the UE failing to read the PCCH channel for 3 consecutive times as a PCCH channel failure event, and taking the reporting of the failure event information as an example when the UE enters the connected state. The process can be as follows figure 2 shown, including:

[0053] Step 201, the network side equipment of cell A sends a system message, which indicates that all UEs in cell A need to record the event when receiving the PCCH fails, and indicates that when the UE continuously reads the PCH channel corresponding to the PICH (carrying PCCH data) If the failure exceeds 3 times, it is considered that a PCCH reception failure event has occurred, and when the event occurs, th...

[0062] Example 2: The network sets the UE with the positioning function in the cell to record the failure event of reading the PCCH channel (decoding HS-DSCH), and receives the failure event reported by the UE according to the indication to perform PCCH optimization. The process is described by taking the UE failing to read the PCCH channel for 3 consecutive times as a PCCH channel failure event, and taking the reporting of the failure event information as a regular report as an example. The process can be as follows image 3 shown, including:

[0063] Step 301, the network side equipment of cell B sends a system message, which indicates that the UE with GPS positioning capability in cell B needs to record the event when it fails to read the PCCH, and indicates that when the UE continuously reads the HS-DSCH corresponding to the PICH If the channel (carrying PCCH data) fails more than 3 times, it is considered that a PCCH reading failure event occurs, and when the event occur...

[0072] Example 3: The network sets the cell to be in the CELL_PCH or / and URA_PCH state (wherein, the UE in the CELL_PCH state means that the UE does not have a dedicated physical channel, selects the PCH according to the algorithm provided by the network, and uses DRX to monitor the state of the PICH, and the UE is in the URA_PCH state The state is similar to the CELL_PCH state, except that the cell update (Cell Update) process is not performed after cell reselection), the UE records the failure event of receiving the PCCH channel (decoding HS-DSCH), and the process of performing PCCH optimization according to the failure event reported by the UE according to the indication . This process is described by taking the UE failing to read the PCCH channel for 3 consecutive times as a PCCH channel failure event, and reporting the failure event information as an example when the UE enters the CELL_DCH state. The process can be as follows Figure 4 shown, including:

Abstract

The invention discloses a method, device and system for optimizing a PCCH (Paging Control Channel) of a TDD (Time Division Duplex) system. The method comprises the following steps: a network side indicates that user equipment records PCCH paging failure information and reports the PCCH paging failure information when failing in receiving a PCCH paging message; the network side receives the PCCH paging failure information recorded and reported by the user equipment according to an indication; and the network side optimizes the PCCH according to the received PCCH paging failure information. By adopting the invention, the PCCH is optimized according to the information reported by the user equipment, therefore, the basis for optimizing the PCCH is more complete, the cost is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to a network optimization technology in the field of wireless communication, in particular to a method and system for optimizing a PCCH channel in a TDD system. Background technique [0002] In the existing TDD (Time Division Duplex, Time Division Duplex) system, including such as TD-SCDMA (Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access technology) and its evolution system network, such as, HSDPA ( High Speed ​​Downlink Packet Access, high-speed downlink packet access) system, HSUPA (High Speed ​​Uplink Packet Access, high-speed uplink packet access) system, HSPA+ (HSPA evolution, where HSPA is the abbreviation of High Speed ​​Packet Access, that is, high-speed packet access Incoming) system, usually by means of drive test to check the coverage quality of the network and whether the system performance meets the expected requirements of the design. The road test work mai...
