    • A method enabling a service at a communication network node and a network node adapted to execute the method is provided, wherein a first request, requesting for one or more operations to be associated with a symbol, is received from a first user. The request comprises an instruction, identifying one or more operations. The request triggers the generating of a unique symbol identity, and the creation of a symbol record, associated with the symbol identity, wherein the symbol record, linking the symbol identity to the one or more operations. At the node the symbol identity is also associated with the generated symbol, which is created by a symbol server and forwarded to the first user. Once the symbol has been received by the node in a second request, the symbol identity corresponding to the symbol is retrieved from the symbol server, and the service is enabled by executing the one or more operations according to the symbol record identified by the symbol identity.
    • 提供一种在通信网络节点和适于执行该方法的网络节点中实现服务的方法,其中从第一用户接收请求与符号相关联的一个或多个操作的第一请求。 该请求包括识别一个或多个操作的指令。 该请求触发生成唯一的符号标识,以及创建与符号标识相关联的符号记录,其中符号记录将符号标识链接到一个或多个操作。 在节点处,符号标识也与由符号服务器创建并转发给第一用户的生成符号相关联。 一旦节点在第二请求中已经接收到符号,则从符号服务器检索对应于符号的符号标识符,并且通过根据符号标识识别的符号记录执行一个或多个操作来启用该服务 。
