Method and terminal for terminal selection of cell

Abstract

The invention provides a method for selecting a community by a terminal and the terminal, and relates to the technical field of wireless networks. The method comprises the steps of: when detecting that the terminal is in radio link failure in the community, acquiring the quantity and the type of currently ongoing business; according to the quantity and the type of the business, starting a corresponding community selecting process, and determining the final dwelled community of the terminal. According to the method and the terminal provided by the invention, off-line reconstruction time delay after the radio link failure can be effectively shortened, so that a user can access the network as soon as possible; aiming at concurrence business, the terminal can be further redirected to the better community to promote user experience while keeping network connection and under the premise of meeting basic business requirements at first.

Description

technical field [0001] The invention relates to the field of wireless networks, and provides a method for a terminal to select a cell and the terminal. Background technique [0002] In the process of network evolution, the deployment of new networks is often promoted gradually, and there are usually scenarios where multiple networks coexist. For a TDD (Time Division Duplexing, time division duplex) system, there will be a mix of TD-SCDMA and TD-LTE. In the stage of network deployment, especially in the early stage of TD-LTE network construction, the network construction and network planning are not yet perfect, and there may be areas with weak coverage, which need to provide services together with the TD-SCDMA network, such as figure 1 As shown, in the range of TD-LTE coverage holes, the terminal is prone to wireless link failure (that is, disconnection), resulting in service interruption. At this time, the terminal needs to select a new cell to reside on based on the re-est...

Problems solved by technology

[0007] The above process tends to give priority to terminals staying on the LTE network when disconnecting from the network, which is convenient for providing reliable business services. However, it is not optimized according to the specific business needs when disconnecting from the network, which will lead to a long time for cell selection and seriously affect user experience. Especially in the initial stage of LTE network construction, due to the imperfect network coverage, there is a scenario where LTE and UTRA are mixed. After the terminal is disconnected from the network, it is likely to need to reside on the UTRA network to continue to provide services, and the above process will cause the terminal to take a long time In the state of searching for the LTE network, the overall off-network reconstruction delay is too long, especially when there are multiple concurrent services during off-network, which will seriously affect service performance and user experience
