Problems solved by technology

[0005] When the service carried by the intertransfer carrier frequency F2 in the carrier intertransfer area A area is converted from 1X to DO, and the 1X service moves from the carrier non-interchange area to the carrier intertransfer area, the services established on F2 will be unable to perform call dropped

Embodiment Construction

[0028] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] figure 2 It is a flow chart of a method for avoiding call drop in a 1X-DO carrier interswitching border area provided by an embodiment of the present invention, as shown in figure 2 As shown, the steps include:

[0030] Step S201, setting up an isolated area between the carrier inter-transfer area and the carrier non-inter-transfer area for 1X-DO service inter-exchange.

[0031] A specific isolation zone is added outside the carrier inter-transfer area to reduce the interference of the carrier frequency F2 carrying 1X services in the carrier non-interchange area to the inter-transfer carrier frequency F2 carrying DO services in the carrier inter...

Abstract

The invention discloses a method for avoiding handover drop in a 1X-DO (data optimized) carrier transfer boundary zone, and relates to the field of CDMA (code division multiple access) mobile communication. The method comprises the following steps: setting an isolation zone between a carrier transfer zone and a carrier non-transfer zone for the 1X-DO business; and when a terminal initiates a calling for establishing business connection in a boundary zone of the isolation zone and the carrier non-transfer zone, judging if the business carried in a transfer carrier frequency in the carrier transfer zone is converted from the 1X business to the DO business by a base station, the base station indicates the terminal to perform the carrier frequency switching operation if judging that the business carried in the transfer carrier frequency in the carrier transfer zone is converted from the 1X business to the DO business, so that the 1X business can be established on the non-transfer carrier frequency as far as possible; and the base station does not indicate the terminal to perform any carrier frequency switching operation if judging that the business carried in the transfer carrier frequency in the carrier transfer zone is not converted from the 1X business to the DO business. The method for avoiding the handover drop in the 1X-DO (data optimized) carrier transfer boundary zone disclosed by the invention solves the handover drop problem of the 1X business in the boundary zone.

Description

technical field [0001] The invention relates to the field of code division multiple access CDMA mobile communication, in particular to a method for solving the problem of call drop in 1X-DO carrier interswitching boundary area switching. Background technique [0002] Voice ARPU (Average Revenue Per User, average revenue per user) has dropped to around US$2, while data ARPU remains at around US$10. The wireless data market in India has great potential for development. Therefore, operators are vigorously promoting the large-scale deployment of wireless data networks to enhance their competitiveness in terms of network coverage, performance and services. [0003] For operators limited by carrier frequency points, technological evolution and solutions for improving spectrum efficiency are urgently needed. Therefore, a solution such as 1X-DO carrier exchange is proposed, which can be softly upgraded through the live network, and the terminal on the live network does not need to ...
