  • Publication number: 20240121589
    Abstract: A unit is provided through an application of a disaster condition to a PLMN in 5GS, the unit being for transmitting and/or receiving a notification in a case that a communication service cannot be provided to a UE and for selecting a roaming destination PLMN by the UE. Provided are a procedure to allow the UE to recognize a state of a certain PLMN and transmit and/or receive information for appropriately selecting a PLMN as a moving destination in a case that a disaster condition applies or no longer applies to the certain PLMN, a method of selecting a PLMN based on information received and stored by the UE through a notification from the PLMN or the like, and a communication unit.

  • Patent number: 11548910
    Abstract: The invention provides a novel method for producing an oligonucleotide using a nucleoside or oligonucleotide that is easy to isolate and has high storage stability. The oligonucleotide production method includes a step of subjecting a nucleoside or oligonucleotide having a pseudo solid phase-protecting group in at least one location selected from the group consisting of 2?-position, 3?-position, 5?-position and a nucleobase moiety and having a 5?-hydroxyl group or a 3?-hydroxyl group, to H-phosphonation to convert the 5?-hydroxyl group or the 3?-hydroxyl group into an H-phosphonated form.
    Type: Grant
