3G (The third Generation Telecommunication) and Ad hoc heterogeneous network switchover method

Abstract

The invention discloses a 3G (The third Generation Telecommunication) and Ad hoc heterogeneous network switchover method. According to the 3G and Ad hoc heterogeneous network switchover method, a calling mobile terminal and a called mobile terminal communicate with each other through a 3G network and an Ad hoc network. The 3G and Ad hoc heterogeneous network switchover method comprises the following steps of: (1) measuring the RSCP (Received Signal Code Power) of a PCCPCH (Primary Common Control Physical Channel) of a base station in an active set and a candidate set of the 3G network, and measuring a signal state of the Ad hoc network simultaneously; (2) switching the 3G network to the 3G network; (3) switching the 3G network to the Ad hoc network; and (4) switching the Ad hoc network to the 3G network. According to the 3G and Ad hoc heterogeneous network switchover method provided by the invention, the properties of the heterogeneous network can be improved; the switchover delay is reduced; and the reliability requirement under an end-to-end time delay limitation condition of a real-time service can be met... The 3G and Ad hoc heterogeneous network switchover method is excellent in properties and easy to realize.

Description

technical field [0001] The invention relates to the field of heterogeneous networks, in particular to a method for switching between 3G and Ad hoc heterogeneous networks. Background technique [0002] Handover is an important resource management function in wireless communication systems, and it is also a unique function and key feature of cellular systems. Handover can be considered as one of the most complex and important processes in cellular communication. [0003] Reasons for switching are generally as follows: [0004] 1. When a mobile terminal enters another cell from one cell, in order to avoid call drop or data link disconnection, a handover process may be triggered. [0005] 2. In a non-CDMA system, the channel used by a mobile terminal may interfere with the channel used by a certain mobile terminal in an adjacent cell. In this case, switching the communication channel of the mobile terminal to a different channel of the same cell or a different channel of an a...
