Abstract
A method for providing crowd sourced navigation alerts including receiving, at a User Equipment (UE), an Multimedia Broadcast Multicast Service (MBMS) start session message when the UE is located within a predefined MBMS area. The method may further include receiving traffic message data, which includes information regarding at least one traffic event, over the MBMS session, where the traffic message data may be based on at least one traffic notification provided by at least one second UE. The method may also include comparing a distance from the UE to a position of the at least one traffic event described in the traffic message data to at least one threshold, and providing at least one alert associated with the at least one traffic event based on the comparing.

A method, comprising:
- receiving, at a first User Equipment (UE), a Multimedia Broadcast Multicast Service (MBMS) start session message when the first UE is located within a predefined MBMS area;
- receiving traffic message data, which includes information regarding at least one traffic event, via an MBMS session, wherein the traffic message data is based on at least one traffic notification provided by at least one second UE;
- comparing a distance from the first UE to a position of the at least one traffic event described in the traffic message data to at least one threshold;
- and
- providing at least one alert associated with the at least one traffic event based on the comparing.
A user equipment (UE), comprising:
- a wireless interface that communicates over a wireless channel;
- a memory configured to store instructions;
- and
- a processor, coupled to the wireless interface and the memory, wherein the processor is configured to execute the instructions stored in the memory to:
- receive a Multimedia Broadcast Multicast Service (MBMS) start session message when the UE is located within a predefined MBMS area,
- receive traffic message data, which includes information regarding at least one traffic event, via an MBMS session, wherein the traffic message data is based on at least one traffic notification provided by at least one second UE,
- compare a distance from the UE to a position of the at least one traffic event described in the traffic message data to at least one threshold, and
- provide at least one alert associated with the at least one traffic event based on the comparing.
A method, comprising:
- receiving, at a Navigation Alert System (NAS), a traffic notification from at least one User Equipment (UE);
- determining a suggested Multimedia Broadcast Multicast Service (MBMS) service area based the received traffic notification;
- generating a traffic alert request, wherein the traffic alert request includes the suggested MBMS service area and an approximate position of a traffic hazard;
- determining session attributes for an MBMS transmission, based on the traffic alert request, wherein the session attributes include an MBMS area based on the suggested MBMS service area;
- establishing at least one MBMS bearer and multicast address based on the session attributes;
- and
- providing multicast traffic message data over the at least one MBMS bearer to base stations serving the MBMS area.
