Example embodiments are directed towards network slicing for multi-tenant location based services in a wireless telecommunication network. For each tenant of the plurality of tenants of the network, the system receives a request from the tenant for location based services for mobile devices of the tenant operating on the respective network slice defined for the tenant. In response to the request, the system provides the customized location based services to the tenant based on the respective network slice being associated with one or more location based services network functions or location based services systems of the wireless telecommunication network, which provide geographical locations of mobile devices operating on the wireless telecommunication network. The location based services network functions or location based services systems may include the location management function (LMF) and the Gateway Mobile Location Centre (GMLC) gateway node.
