Methods and devices of enabling paging of a wireless communication device. In an aspect, a method of a node configured to provide core network user plane functionality in a communications network is provided to enable paging of a wireless communication device being in an idle state. The method includes receiving an indication that data is to be transmitted in downlink to the wireless communication device, identifying a radio access network control plane function, and sending a downlink data notification comprising an identifier of the wireless communication device and of a core network control plane function configured to provide mobility management where the wireless communication device currently is registered, thereby enabling for the identified radio access network control plane function to forward the download data notification to the identified core network control plane function configured to provide mobility management to enable the identified core network control plane function configured to provide mobility management to page the wireless communication device.

There is provided a method of operating a message processing node in a message processing system. Upon receipt of a message for a transaction referring to an object for which a record is stored in a database (), a request is sent to the database to lock the record for the object (). Where the record is unlocked, a message is received from the database indicating that the request to lock the record is successful () and the received message for the transaction is processed (). Where the record has been locked previously by another message processing node, a message is received from the database indicating that the request to lock the record is unsuccessful and identifying the message processing node to which the record is locked () and the received message for the transaction referring to the object is forwarded to the identified message processing node ().
