Study on the enhancement of protocols for SMS service over SGs
The present document is a study on alternative protocols for the SMS over SGs architecture. Several involved interfaces are using MAP protocols for which alternative protocols will be analysed.
After addressing the requirements to introduce these protocol alternatives, the TR will identify which MAP procedures on the different interfaces for SMS need to have their equivalent with alternative protocols and will give their description with them. Interworking with other networks will be analysed with the possible use of interworking functions.
It will compare solutions with alternative protocols and make recommendations.
