We disclose a new type of wireless telecommunications subscription service and related methods. In some embodiments, the new subscription service may be used by an eCall only MS, or by any other suitable wireless access device (NAD), in order to operate in a restricted access and mobility management (RAMM) mode (304). The RAMM service limits usage of network resources, while enabling utilization for certain limited kinds of calls. The service may be used for eCall, in the case of motor vehicles (FIG. 1 ), for example, or for machine to machine communications and remote alarms (FIG. 6). The new subscription service may be used to avoid an eCall only MS being denied access to a network due to non-use of a prepaid (USIM) subscription (314). |
