TELEMATICS SUPPORT FOR MOBILE WIRELESS NETWORK SERVICE SWAPPING

摘要

A method for implementation at a processor of a vehicular telematics unit is described. The method allows data structures formatted to store one or more wireless network communication parameters to be updated in response to a swap of a subscription with one network service provider for a subscription with a different network service provider. The method includes receiving, from a network access device of the vehicular telematics unit, a home public land mobile network (HPLMN) identifier corresponding to a wireless network service provider corresponding to an active subscription. The method also includes identifying, in a set of one or more access point name (APN) data structures each having a public land mobile network (PLMN) identifier field, a matching APN data structure having the HPLMN identifier stored at its PLMN element and designating the matching APN data structure as active.

主权项

1. A method, implemented at a processor of a vehicular telematics unit, for updating data structures formatted to store one or more wireless network communication parameters, the method comprising:
receiving, from a network access device (NAD) of the vehicular telematics unit, a home public land mobile network (HPLMN) identifier corresponding to a first mobile wireless network service provider (MWNSP); identifying, in a set of one or more access point name (APN) data structures each having a public land mobile network (PLMN) identifier element, a matching APN data structure having the HPLMN identifier stored at its PLMN element; and designating the matching APN data structure as active.
