1. A method comprising:
- receiving, in a network element of a packet data core network, a network resource request from a user equipment, said request including an indication on the user equipment'"'"'s internet protocol version capability or a request for a particular packet data protocol type;
creating, in said network element, a set of parameters for guiding the user equipment in IP address allocation at least in one packet data network, said set of parameters including at least a recommended version of internet protocol address type to be used and information on a plurality of internet protocol versions transition technologies of the given type in a form of a first priority list recommending the user equipment to use the transition technology with the highest priority to be used by the user equipment when accessing through said packet data network; and
signalling said set of parameters to the user equipment as a response to the network resource request to be used by the user equipment in requesting the recommended version of internet protocol address type, wherein the user equipment selects a transition technology to be used from the first priority list and a second priority list of supported internet protocol versions transition technologies internal to the user equipment.

7. A network element, comprising:
-
at least one processing unit; at least one memory including computer program code, the at least one memory and the computer program code configured to, with at least one processing unit, cause the apparatus to; receive a network resource request from a user equipment, said request including an indication on the user equipment'"'"'s internet protocol version capability or a request for a particular packet data protocol type; create a set of parameters for guiding the user equipment in internet protocol address allocation in at least one packet data network, said set of parameters including at least a recommended version of internet protocol address type to be used and information on a plurality of internet protocol versions transition technologies of the given type in a form of a first priority list recommending the user equipment to use the transition technology with the highest priority, which the user equipment should preferably use when accessed through said packet data network; and signal said set of parameters to the user equipment as a response to the network resource request to be used by the user equipment in requesting the recommended version of internet protocol address type, and wherein the user equipment selects a transition technology to be used from the first priority list and a second priority list internal to the user equipment of supported internet protocol versions transition technologies.

8. An apparatus comprising:
-
an internal priority list of supported internet protocol versions transition technologies; at least one processing unit; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processing unit, cause the apparatus to; transmit a network resource request to a packet data core network, said request including an indication on the internet protocol version capability of the apparatus or a request for a particular packet data protocol type; receive signalling from said packet data core network as a response to the network resource request, said signalling including a set of parameters comprising at least a recommended version of internet protocol address type to be used at least in one packet data network and information on a plurality of internet protocol versions transition technologies of the given type in a form of a second priority list recommending the apparatus to use the transition technology with the highest priority in said the set of parameters to be used when the apparatus accesses through said packet data network; select a transition technology to be used from said priority list and said internal priority list; and request the recommended version of internet protocol address type and refrain from requesting another internet protocol address type, when an application requiring said address type is initiated. - View Dependent Claims (9, 10, 11)

12. A non-transitory computer readable medium storing computer program code that is executable in a data processing device comprising an internal priority list of supported internet protocol versions transition technologies, wherein the computer program code is executable to cause the data processing device to perform:
-
creating a network resource request to be transmitted to a packet data core network, said request including an indication on the internet protocol version capability of the data processing device or a request for a particular packet data protocol type; in response to receiving signalling from said packet data core network as a response to the network resource request, storing a set of parameters received in said signalling in a memory, said set of parameters comprising at least a recommended version of internet protocol address type to be used at least in one packet data network and information on a plurality of internet protocol versions transition technologies of the given type in a form of a priority list recommending the data processing device to use the transition technology with the highest priority, which the user equipment should preferably use when accessed through said packet data network; selecting a transition technology to be used from said priority list and said internal priority list; and requesting the recommended version of internet protocol address type, when an application requiring said address type is initiated.
