Abstract
A method for improving reliability of Voice over LTE (VoLTE)/Video over LTE (ViLTE) calls includes detecting, by a User Equipment (UE) camped on a first Radio Access Technology (RAT), a problem with a radio connection on the first RAT at a first time. After detecting the problem with the radio connection, the UE blocks Non-Access Stratum (NAS) registration on a second RAT in a time period between the first time and a second time later than the first time. The second RAT is different than the first RAT.
Claims20
A method, comprising:
- detecting, by a User Equipment (UE) camped on a first Radio Access Technology (RAT), a problem with a radio connection on the first RAT at a first time;
- and
- blocking, by the UE, Non Access Stratum (NAS) registration on a second RAT in a time period between the first time and a second time later than the first time.
A device camped on a first Radio Access Technology (RAT), comprising:
- a memory;
- and
- at least one processor communicatively coupled with the memory and configured to:
- detect a problem with a radio connection on the first RAT at a first time;
- and
- block Non-Access Stratum (NAS) registration on a second RAT in a time period between the first time and a second time later than the first time.
A non-transitory computer-readable medium containing instructions which, when executed, cause a computing device camped on a first Radio Access Technology (RAT) to perform operations comprising:
- detecting a problem with a radio connection on the first RAT at a first time;
- and
- blocking Non Access Stratum (NAS) registration on a second RAT in a time period between the first time and a second time later than the first time.
