  • Publication number: 20240372656
    Abstract: A Radio Access Network (RAN) system includes a group of cell sites where each cell site includes multiple sectors, and each sector communicates with UE, the system including a Radio Resource Controller (RRC) in Central Unit (CU) controlling PUCCH resources for the sectors, and a Media Access Control (MAC) Scheduler in each sector allocating resources for PUCCH HARQ transmissions in an orthogonal manner separated in time or frequency or cyclic shift to minimize the inter-carrier interference across the sectors to improve system throughput.

  • Patent number: 12120117
    Abstract: A method and system for provisioning credentials is disclosed. The method includes receiving, by a token provider computer, a token request message from a token requestor computer that comprises an initial access identifier. The token provider computer transmits the initial access identifier to a first authorization computer, and then the token provider computer receives an intermediate access identifier. The token provider computer then transmits a token activation request message to a second authorization computer based at least in part on the intermediate access identifier. The token provider computer then receives a token activation response message from the second authorization computer. The token provider computer then provides the token to the token requestor computer.

  • Patent number: 12038946
    Abstract: Connection loss may be minimized for performing database query engine changes. A distributed database system may include different instances of the query engine that provide access to a database. When an event to change the version of the query engine is detected, a copy of the database may be created and a new instance of the query engine created. Read-only access to the database may be maintained using the different instances of the query engine while the new instance may be upgraded to the different version of the query engine. Upon successful installation of the different version of the query engine at the new instance, the new instance may be given read-write access to the database using the copy of the database and other database instances may be upgraded to the different version of the query engine.

  • Publication number: 20230120485
    Abstract: The present embodiments relate to systems and methods for token-for-token provisioning. A server computer can receive a message from a second token requestor. The message can include a request for a second token and can include a first token or the message can include a cryptogram request message. The server computer can transmit a provisioning request message to an authorizing entity computer requesting an authentication of a credential and receive a provisioning response message from the authorizing entity computer authenticating the credential. Any of the server computer or the authorizing entity computer can generate the second token. The server computer can provide the second token to a second token requestor for use in a recurring transaction. The first token and the second token can both be associated with a credential.

  • Publication number: 20220207527
    Abstract: Embodiments of the invention are directed to systems and methods for authenticating a user device using an authenticating device that has previously been associated with a user and/or a credential. The user may initiate a transaction at the user device. An authenticating device associated with the transaction may be sent an authentication request corresponding to the user device. The user may indicate whether or not the user device is authenticated utilizing the authenticating device. If the user device is authenticated, the transaction may proceed. If the user device is not authenticated the transaction may be rejected.

  • Patent number: 11288112
    Abstract: Data loss thresholds are enforced when performing updates to mirrored data sets. When an update is received for a data set that is mirrored to other copies of the data set, an evaluation of the difference between the data set and the other copies of the data set may be performed. If the evaluation determines that the difference fails to satisfy a threshold for acceptable data loss at the other copies upon a failure of the data set, a data loss mitigation action may be applied to performance of the update until the difference satisfies the threshold.

  • Patent number: 11144407
    Abstract: Systems and methods are disclosed to implement a synchronous database mirroring technique using delayed visibility write operations. In embodiments, a durable log of write operations in a primary database is replicated to a secondary database. The two databases do not make corresponding operations durable in a synchronous manner. However, the two databases coordinate to provide a visible view of the two durable logs that is guaranteed be durable in both databases. In embodiments, the primary database may monitor the state of the durable log of the secondary database, and periodically update the visible range of the logs to include operations that have been made durable in both databases. Advantageously, the visible range of the logs is permitted to grow asynchronously from the logs themselves, so that the two databases can provide a synchronized visible view of the log data without placing timing constrains on the data's durability.

  • Patent number: 10929428
    Abstract: Adaptive replication of changes may be performed for copies of a database. Log records may be generated and stored that correspond to changes to a database while a database is being copied. If the changes to be applied to a copy of the database is less than or equal to a threshold number of changes, then the copy of the database may be updated using the stored log records. If the changes to be applied to the copy of the database are greater than the threshold number of changes, then the copy of the database may be updated using data stored in the database.
