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

Example Embodiment

[0052] Example 1: The network sets the UE in the cell to record the failure event of receiving the PCCH channel (ie, decoding the PCH), and the process in which the receiving UE performs the PCCH optimization according to the failure event information reported by the indication. This process is described by taking the case that the UE fails to read the PCCH channel three times continuously, which is regarded as a PCCH channel failure event, and the method of reporting the failure event information is to report when the UE enters the connected state. The process can be like figure 2 Shown, including:

[0053] Step 201: The network side device of cell A sends a system message, which indicates that all UEs in cell A need to record the event when receiving PCCH failed, and indicate 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 wh...

Example Embodiment

[0062] Example 2: The network sets the UE with positioning function in the cell to record the failure event of reading the PCCH channel (decoding the HS-DSCH), and the process of receiving the failure event reported by the UE to perform PCCH optimization according to the indication. This procedure is described by taking as an example that the UE fails to read the PCCH channel three times continuously, which is regarded as a PCCH channel failure event, and the method of reporting the failure event information is timing reporting. The process can be like image 3 Shown, including:

[0063] Step 301: The network side device 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 reading the PCCH fails, 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 has oc...

Example Embodiment

[0072] Example 3: The network sets the cell in the CELL_PCH or / and URA_PCH state (where the UE is in the CELL_PCH state means that the UE does not have a dedicated physical channel. The PCH is selected according to the algorithm provided by the network, and the DRX mode is used to monitor the state of the PICH. The UE is in the URA_PCH The status is similar to the CELL_PCH status, except that the cell update process is not performed after the cell reselection.) The UE records the PCCH channel (decoding HS-DSCH) failure event, and the process of PCCH optimization by the receiving UE according to the failure event reported by the indication . This process is described by taking the case that the UE fails to read the PCCH channel three times continuously, which is regarded as a PCCH channel channel failure event, and the method of reporting the failure event information is to report when the UE enters the CELL_DCH state. The process can be like 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...
