Abstract: In some examples, a source device categorizes a plurality of messages for transmission to a recipient device, the plurality of messages comprising vehicle-related information. Based on the categorizing, the source device identifies selected messages of the plurality of messages to be aggregated. The source device aggregates the selected messages into a single transmission from the source device to the recipient device.

Abstract: In some examples, a wireless device receives, from a wireless access network node, an indication of a supported extended emergency information (EEI) type supported by a wireless local area network (WLAN). The supported EEI type is selected from among a plurality of different EEI types. The wireless device sends a message relating to an emergency call, the message including EEI data according to the supported EEI type.

Abstract: In some examples, an access point determines, based on at least one criterion that includes a non-time based criterion, whether to activate group-addressed transmission of information relating to an access network. In response to determining, based on the at least one criterion, to activate group-addressed transmission of information relating to the access network, the access point transmits information relating to the access network in a message targeted to a group address.
