Embodiment Construction

[0024] The invention provides a method for allocating channel resources in a hybrid network mode composed of a mobile ad hoc network and a cellular network. The core idea is: firstly, the available resources are determined jointly by the cellular network and the mobile ad hoc network; the cellular network system (radio network controller) is responsible for the allocation of the cellular network channels, so the terminal can know the channel allocation status of the cellular network from the system; at the same time, Each terminal in the mobile ad hoc network can know the channel resources used by adjacent terminals through carrier sense; therefore, when the mobile ad hoc network is within the coverage of the cellular network, the available channel resources of the hybrid network are mobile ad hoc network and the intersection of idle channels in the cellular network, or, when the mobile ad hoc network part is outside the coverage of the cellular network, the available channel r...

Abstract

A method for distributing channel in mixed network MN includes sending public control information of mobile self-organized network (SON) by channel preset in cellular network (CN), monitoring the first service channel distribution message in preset channel by terminal in MN and obtaining the second service channel distribution message used for CN communication and down-sent by base station, selecting idle service channel for call in mobile SON and issuing service call request in preset channel by said terminal according to channel occupation information of two said distribution messages, distributing service channel to said terminal by CN for realizing CN mode call with base station.

Description

technical field [0001] The invention relates to a channel allocation method of a mixed network system, in particular to a channel allocation method in a mixed network system of a mobile ad hoc network and a cellular network. Background technique [0002] The network structure of the cellular network is a common network structure of the existing mobile communication system. The centralized wireless channel allocation method is adopted in the cellular network, that is, a central control device such as a base station or a service access point is required. Taking the current GSM and CDMA mobile communication systems as an example, the radio network controller (BSC / RNC) manages and allocates radio resources, and notifies the terminal of the allocated traffic channel through the base station in the downlink common channel. [0003] The mobile ad hoc network is another general mobile communication mode besides the cellular network. The mobile ad hoc network is a multi-hop temporar...
