Contribution to SMS management over 4G network in distance education context
In parallel to the using of resources implemented for distance learning, learners appreciate send and receive SMS. Although 4G offers very high data rates and adaptable quality of service, it does not support the SMS legacy service of GSM. 3GPP is currently specifying two architectures for SMS transmission: SMS over SGs, and SMS over IMS. However, when the learner uses a 4G service, to send or receive a SMS, he is first switched to 3G, which interrupts the current service on 4G. It is in this context that we propose a solution that permits to learner to send or receive SMS while continuing to use his service on the 4G network.
