  • Patent number: 11818139
    Abstract: A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.

  • Patent number: 11799968
    Abstract: A communications method and apparatus are provided. The method includes: A first access network device sends a first message to a core network device, where the first message is used to indicate to suspend one or both of a first PDU session and a second PDU session. The first PDU session and the second PDU session are PDU sessions that are established as requested by a same terminal, and are used to transmit a duplicated data packet. According to the method, when a condition for implementing reliable transmission is not met, the core network device can be indicated to suspend the PDU session. In this way, a PDU session does not need to be re-established, and signaling overheads for establishing the PDU session are saved.

  • Publication number: 20230295594
    Abstract: The invention relates to method for the efficient expression and purification and application of a recombinant fusion protein of MANNase and homologues thereof and GLP-1. Through genetic recombination technology, soluble proteins are obtained by using high density fermentation of Pichia pastoris to induce secretory expression, followed by isolation and purification by filtration and concentration to obtain high yield of target proteins. The high fermentation expression and simple isolation steps solve the limitations of the current GLP-1 analogs such as low drug yield, high cost and the need for frequent injections. More importantly, the fusion protein has hypoglycemic effect not only by injection, but also by oral administration for hypoglycemia and weight reduction, which has good application value in obese and pre-diabetic patients. It also provides a basis for further research on the mechanism of hypoglycemia and weight loss of mannanase and homologues thereof with GLP-1 recombinant fusion protein.
