  • Publication number: 20220374226
    Abstract: The invention relates to the filed of the Internet of Things, and in particular, to an OTA differential upgrade method and system of a master-slave architecture. The method comprises: Step S1, obtaining an upgrade scheme, and determining a master-slave connection relationship and an upgrade manner according to the upgrade scheme; Step S2, downloading a differential upgrading file; Step S3, determining a processing mode of a master node according to the upgrading manner of a slave node; if the upgrading manner of the slave node is a first manner, the node flashes and restores the differential upgrading file and sends the differential upgrading file to the slave node, so that the slave node completes upgrading; if the upgrading manner of the slave node is a second manner, the master node flashes and restores the differential upgrading file and sends the differential upgrading file to the slave node for upgrading.

  • Patent number: 11223978
    Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to an information transmission method, an information modification method, and apparatuses, so as to solve a technical problem of voice transmission interruption in an SRVCC scenario in the prior art. In embodiments of the present invention, when a UE is in a connected state, a base station is notified of an SRVCC capability of the UE in real time, so that the base station can update the locally stored SRVCC capability of the UE in real time, and then determine, according to an actual situation, whether to initiate an SRVCC process, thereby ensuring a success rate of the SRVCC process and avoiding a possible phenomenon of call drop as far as possible.
