An apparatus and method for creating a finite blockchain is provided. The blockchain comprises a genesis block that is the first block of the blockchain. The genesis block comprising a genesis expiry time. The method comprises the steps of creating a reincarnation block when a predefined condition is satisfied and appending it to the blockchain; determining whether the genesis expiry time has elapsed based on an expiry period; if the genesis expiry time has elapsed then identifying a first reincarnation block; if the first reincarnation block is identified then deleting all the blocks preceding the first reincarnation block including the genesis block in the block chain.

Method and apparatus for creating a finite blockchain

A method and a wireless transmit/receive unit (WTRU) (), including a universal subscriber identity module USIM (), for identifying a closed subscriber group (CSG) cell are disclosed. The WTRU () receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU () determines whether the CSG ID is programmed in the USIM (). The cell broadcast may include a single bit information element (IE) indicating that the cell is a CSG cell. If the cell ID is a CSG ID, the cell ID may further include a plurality of fields which indicate at least one of a country, a region, an operator, and a home evolved Node-B (HeNB) number. The cell broadcast may further include a bit indicating whether the CSG cell is public or private. The cell broadcast may further include a bit indicating that emergency calls are allowed from all users.
