Location information services or location management systems in VCN (Vehicular Communication Networks) are used to provide location information about vehicles such as current location, speed, direction and report this information to other vehicles or network entities that require this information. This paper designs firstly an EDQS (Extended Dynamic Quorum System) which is a logical structure for location management of VCNs. Secondly, we propose a QAHLS (Quorum-based Adaptive Hybrid Location Service) on the basis of the EDQS which uses direct location scheme mixed with indirect location scheme according to the location preference and the location mobility for a vehicle. The performance of QAHLS is evaluated by an analytical model and compared with that of existing GQS (Grid Quorum System) based and DQS (Diamond Quorum System) based location services.
