IP-based paging for DSDS

摘要

A method is disclosed for paging of a terminal having a first subscriber identity (IMSI1) attachable to a first mobile communication network (101) and a second subscriber identity (IMSI2) attachable to a second mobile communication network (201). The method is performed in a controller node (213; 600) of the second mobile communication network and involves registering (310, 410) the terminal's second subscriber identity (IMSI2) as attached to the second mobile communication network (201), followed by registering (320, 420) an auxiliary paging address (422) for the terminal's second subscriber identity. Then, a need to page the terminal's second subscriber identity is determined (330), and the terminal's second subscriber identity is paged (340). The paging involves sending (240) an auxiliary paging message (442) to the registered auxiliary paging address, and the auxiliary paging message is adapted for delivery to the terminal's first subscriber identity (IMSI1).
