Abstract
A method and apparatus can be configured to transmit first policy rules to a packet-data-network gateway. The first policy rules are configured to be installed on the packet-data-network gateway. The first policy rules are configured to enable the packet-data-network gateway to create first route-header information. The method can also include transmitting second policy rules to an interworking gateway. The second policy rules are configured to be installed on the interworking gateway. The second policy rules are configured to enable the interworking gateway to create second route-header information.
Claims11
A method, comprising:
- transmitting, by a network entity, first policy rules to a packet-data-network gateway, wherein the first policy rules are configured to be installed on the packet-data-network gateway, and the first policy rules are configured to enable the packet-data-network gateway to create first route-header information;
- and
- transmitting second policy rules to an interworking gateway, wherein the second policy rules are configured to be installed on the interworking gateway, and the second policy rules are configured to enable the interworking gateway to create second route-header information, wherein the packet-data-network gateway and the interworking gateway are distinct entities.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to
- transmit first policy rules to a packet-data-network gateway, wherein the first policy rules are configured to be installed on the packet-data-network gateway, and the first policy rules are configured to enable the packet-data-network gateway to create first route-header information;
- and
- transmit second policy rules to an interworking gateway, wherein the second policy rules are configured to be installed on the interworking gateway, and the second policy rules are configured to enable the interworking gateway to create second route-header information,
- wherein the packet-data-network gateway and the interworking gateway are distinct entities.
A computer program product, embodied on a non-transitory computer readable medium, the computer program product configured to control a processor to perform a process, comprising:
- transmitting, by a network entity, first policy rules to a packet-data-network gateway, wherein the first policy rules are configured to be installed on the packet-data-network gateway, and the first policy rules are configured to enable the packet-data-network gateway to create first route-header information;
- and
- transmitting second policy rules to an interworking gateway, wherein the second policy rules are configured to be installed on the interworking gateway, and the second policy rules are configured to enable the interworking gateway to create second route-header information,
- wherein the packet-data-network gateway and the interworking gateway are distinct entities.
