METHODS AND SYSTEMS FOR SERVICE ENABLER DATA DELIVERY FLOW MANAGEMENT
A SEALDD server may receive a request to establish a SEALDD flow, wherein the SEALDD flow facilitates a transfer of VAL data between a VAL client endpoint and a first VAL server endpoint, and wherein the request comprises at least one of VAL client endpoint information and first VAL server endpoint information. The SEALDD server may establish a SEALDD flow associated with the first VAL server and associated with at least one VAL client endpoint. The SEALDD server may subscribe to a core network and receive a notification from the core network indicating a UE mobility event associated with a UE upon which the VAL client is hosted. The SEALDD server may determine to transfer the VAL client to a second VAL server. The SEALDD server may transfer the SEALDD flow to a different SEALDD server associated with the second VAL server.
1 . A method comprising:
receiving, by a first service enabler architecture layer for data delivery (SEALDD) server and from a SEALDD client, a request to establish a SEALDD flow, wherein the SEALDD flow facilitates a transfer of vertical application layer (VAL) data between a VAL client endpoint and a first VAL server endpoint, and wherein the request comprises at least one of VAL client endpoint information and first VAL server endpoint information;
processing, by the first SEALDD server, the request by establishing a SEALDD flow associated with the first VAL server and associated with at least one VAL client endpoint specified in the request;
subscribing, by the first SEALDD server, to a core network;
receiving, by the first SEALDD server and based on the subscribing to the core network, a notification from the core network indicating a user equipment (UE) mobility event associated with a UE upon which the VAL client is hosted;
determining to transfer the VAL client to a second VAL server based on the mobility event; and
transferring, by the first SEALDD server, the SEALDD flow to a second SEALDD server associated with the second VAL server.
2 . The method of claim 1 , further comprising a SEALDD flow identifier assigned by the SEALDD client.
3 . The method of claim 1 , wherein the VAL client endpoint information and the VAL server endpoint information further comprise at least one of a VAL client identifier, an internet protocol (IP) address, a port, or a uniform resource locator (URL).
4 . The method of claim 1 , wherein transferring the SEALDD flow to the second SEALDD server further comprises the first SEALDD server sending a request to push SEALDD flow information to the second SEALDD server.
5 . The method of claim 1 , wherein transferring the SEALDD flow to the second SEALDD server further comprises the second SEALDD server sending a request to pull SEALDD flow information from the first SEALDD server.
6 . The method of claim 1 , wherein transferring the SEALDD flow to the second SEALDD server further comprises sending, by the first SEALDD server, a SEALDD flow identifier to the second SEALDD server.
7 . The method of claim 1 , further comprising sending a response to the SEALDD client comprising an indication of successful establishment of the SEALDD flow.
8 . The method of claim 1 , further comprising sending a response to the SEALDD client comprising at least one of a first SEALDD server IP address or a first SEALDD server uniform resource identifier (URI).
9 . A first service enabler architecture layer for data delivery (SEALDD) server apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the first SEALDD server apparatus to:
receive, from a SEALDD client, a request to establish a SEALDD flow, wherein the SEALDD flow facilitates a transfer of vertical application layer (VAL) data between a VAL client endpoint and a first VAL server endpoint, and wherein the request comprises at least one of VAL client endpoint information and first VAL server endpoint information;
process the request by establishing a SEALDD flow associated with the first VAL server and associated with at least one VAL client endpoint specified in the request;
subscribe to a core network;
receive, based on the subscribing to the core network, a notification from the core network indicating a user equipment (UE) mobility event associated with a UE upon which the VAL client is hosted;
determine to transfer the VAL client to a second VAL server based on the mobility event; and
transfer the SEALDD flow to a second SEALDD server associated with the second VAL server.
10 . The apparatus of claim 9 , further comprising a SEALDD flow identifier assigned by the SEALDD client.
11 . The apparatus of claim 9 , wherein the VAL client endpoint information and the VAL server endpoint information further comprise at least one of a VAL client identifier, an internet protocol (IP) address, a port, or a uniform resource locator (URL).
12 . The apparatus of claim 9 , wherein causing the apparatus to transfer the SEALDD flow to the second SEALDD server further comprises causing the apparatus to send a request to push SEALDD flow information to the second SEALDD server.
13 . The apparatus of claim 9 , wherein causing the apparatus to transfer the SEALDD flow to the second SEALDD server further comprises the second SEALDD server sending a request to pull SEALDD flow information from the apparatus.
14 . The apparatus of claim 9 , wherein causing the apparatus to transfer the SEALDD flow to the second SEALDD server further comprises causing the apparatus to send a SEALDD flow identifier to the second SEALDD server.
15 . The apparatus of claim 9 , further comprising causing the first SEALDD server apparatus to send a response to the SEALDD client comprising an indication of successful establishment of the SEALDD flow.
16 . The apparatus of claim 9 , further comprising causing the first SEALDD server apparatus to send a response to the SEALDD client comprising at least one of a first SEALDD server apparatus IP address or a first SEALDD server apparatus uniform resource identifier (URI).
17 . A method comprising:
sending, by a service enabler architecture layer for data delivery (SEALDD) client and to a first SEALDD server, a request to establish a SEALDD flow, wherein the SEALDD flow facilitates a transfer of vertical application layer (VAL) data between a VAL client endpoint and a VAL server endpoint, and wherein the request comprises at least one of VAL client endpoint information and VAL server endpoint information;
receiving an indication of an establishment of a SEALDD flow associated with the VAL server and with at least one VAL client endpoint specified in the request;
determining occurrence of a user equipment (UE) mobility event of a UE upon which the VAL client is hosted; and
receiving, from the first SEALDD server, a transfer of the SEALDD flow to a second SEALDD server associated with the VAL server.
18 . The method of claim 17 , further comprising a SEALDD flow identifier assigned by the SEALDD client.
19 . The method of claim 17 , wherein the VAL client endpoint information and the VAL server endpoint information further comprise at least one of a VAL client identifier, an internet protocol (IP) address, a port, or a uniform resource locator (URL).
20 . The method of claim 17 , further comprising receiving, from the first SEALDD server, at least one of an indication of successful establishment of the SEALDD flow, a first SEALDD server IP address, or a first SEALDD server uniform resource identifier (URI).
