The invention relates to mobility management in an Internet-type protocol traffic in a mobile communications network. At least one of mobile exchanges (DXT1, DXT2) in the mobile communication network is arranged to dynamically allocate an IP address to a mobile host (MH) from an address space of the mobile communications network for a lease period and to associate the allocated IP address with a user identity (SSI) and a data equipment identity (NSAPI) used for identifying the mobile host (MH) in the mobile communication network. |
