receiving, from a network function that handles connection and mobility management tasks in a subsequent-generation visited network, a first data in a subsequent- generation context (i.e., node 104 receives the message transmitted by 5G-RAN 102 in step 306 and, in response, identifies the default QoS flow and GBR QoS flows per PDU session based on associated QoS characteristics; see paragraph [0067]), wherein the first data in the subsequent-generation context is originated by a request from a subsequent-generation capable user equipment (UE) to use a precedent- generation network service (for example, the UE transmitting a registration request message comprising information identifying a set of one or more translation methods for mapping 5G QoS flows to 4G bearers that are supported by the UE.; see paragraph [0029]);
converting the first data in the subsequent-generation context to a second data in a precedent-generation context (i.e., Node 104 then uses the predetermined translation rule to assign an EPS bearer identifier (ID) to one or more of the identified QoS flows (e.g., a first EPS bearer ID may be assigned to the default QoS flow and other EPS bearer IDs are assigned to the GBR QoS flows); see paragraph [0067]);
sending, to a precedent-generation home network, the second data in the precedent- generation context (i.e., The assigned EPS bearer IDs are then included in a handover message generated by node 104. For example, node 104 may sort the QoS flows in priority order according to the predefined rule. This priority order is used to populate a handover message that is generated by node 104 and sent to node 105.; see paragraphs [0067] and [0071]);
receiving, from the precedent-generation home network, a third data in the precedent-generation context, wherein the third data is a result of processing the second data by the precedent-generation home network (i.e., 4G-RAN 103 receives the Handover Request, reserves resources for the requested bearers (i.e., the bearers identified by the E-RAB IDs included in the transparent container), and generates and acknowledgment (ACK) (e.g., the S1AP message Handover Request Acknowledge)… 4G-RAN 103 transmits the ACK to node 105; see paragraphs [0072]-[0075]);
converting the third data in the precedent-generation context to a fourth data in the subsequent-generation context (i.e., in response to receiving the response message transmitted by node 105, node 104 transmits a handover command to 5G-RAN 102.; see paragraph [0076]); and
sending, to the network function in the subsequent-generation visited network, the fourth data in the subsequent-generation context (i.e., node 104 transmits a handover command to 5G-RAN 102… 5G-RAN 102 receives the handover command and then sends a handover command to UE 101; see paragraphs [0076] and [0077]).
Regarding Claim 11, Larsen discloses wherein a first adaptor is used for
sending and receiving data in the subsequent-generation context, and a second adaptor is used for sending and receiving data in the precedent-generation context (see figure 1).
Regarding Claims 12 and 20, Larsen discloses wherein converting the first data
in the subsequent- generation context to the second data in the precedent-generation context further comprises at least one of: translating information from a subsequent-generation procedure into a precedent-generation procedure, or converting a subsequent-generation identity to a precedent-generation identity (see paragraph [0067]).
Regarding Claim 13, Larsen discloses wherein converting the third data in the
precedent- generation context to the fourth data in the subsequent-generation context further comprises at least one of: translating information from a precedent-generation procedure into a subsequent-generation procedure (see paragraph [0076]), or converting a precedent-generation identity to a subsequent-generation identity.
