Current iDEN technology limits dispatch service to a user's home regional network; future iDEN technology changes will allow users to roam into other regional network and continue to have dis- patch service. In both cases, it would be useful if the end user knew that they were about to roam out of their home regional network. In the case where dis- patch service is not available outside of a user's home regional network (either because the technolo- gy isn't in place or they are not provisioned for roaming dispatch service), users want the ability to know if they about to travel outside of their home regional network and thus lose dispatch service. In the case where a user does have the ability to roam and retain dispatch service, there might be added charges that are incurred when roaming and again users would want to know if they are about to travel outside of their home regional network and thus get charged higher rates for dispatch service.
