Problems solved by technology

However, this solution has several drawbacks
One such drawback is that the use of in-band modem signaling prohibits any modification of the user plane in the network, potentially eliminating the MSD component when sending in-band
This delay jitter is prevalent in modem in-band signaling over packet-based networks, which affects the reliability of MSD delivery
Another drawback: the large amount of redundancy employed in modem in-band signaling to ensure reliable delivery results in very long delivery times

Embodiment Construction

[0018] The following detailed description of the present invention refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. In addition, the following specific embodiments do not limit the present invention.

[0019] The implementation described here involves transferring the MSD associated with the eCall from the mobile station to the PSAP via SMS over SAPI-0. As used herein, eCall may refer to an automatically or manually initiated emergency voice call supplemented by MSD including vehicle-specific and high-precision location information. The MSD may include vehicle type (car / truck), vehicle identification (make and model), time, geographic location of the vehicle, direction the vehicle is traveling, and / or number of passengers in the vehicle, among other types of data. In the 3GPP GSM standard, SAPI-0 represents a specific data link layer service access point, where the data link layer provides servic...

Abstract

A mobile station receives data for sending to a destination device and determines whether to send the data to the destination device via either short message service (SMS) over service access point identifier 0 (SAPI-0) or SMS over SAPI-3, where SAPI-0 and SAPI-3 comprise different service access points associated with a data link layer of a mobile network. The mobile station selectively sends the location information to the destination device via either SMS over SAPI-0, or via SMS over SAPI-3, based on the determination.

Description

technical field [0001] Implementations described herein relate generally to wireless communication systems and, more particularly, to the delivery of Short Message Service (SMS) messages in wireless communication systems. Background technique [0002] The Third Generation Partnership Project (3GPP) involves collaboration among groups of telecommunications associations to create globally applicable 3G mobile phone system specifications. 3GPP standards are based on the Global System for Mobile Communications (GSM) specification and cover standards for radio, core network and service architecture. [0003] Work is currently underway in 3GPP to introduce a new service called eCall. An eCall is an automatically or manually initiated emergency voice call supplemented by a Minimum Set of Data (MSD) including vehicle-specific and highly accurate location information. Using this information, emergency services can pinpoint and provide faster assistance to accident victims, saving m...
