RESTORATION OF A PDN CONNECTION AT PGW FAILURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240098148 titled 'RESTORATION OF A PDN CONNECTION AT PGW FAILURE
Simplified Explanation
The abstract describes a method of operation of a cellular communications system, involving various steps such as receiving an attach request from a user equipment (UE), sending a location update request to a home subscriber server (HSS), sending a DNS query request to a DNS server, selecting a Packet Data Network Gateway (PGW), and creating a session between the UE and Serving Gateway (SGW).
- Receiving attach request from UE
- Sending location update request to HSS
- Sending DNS query request to DNS server
- Selecting a PGW from candidate PGWs
- Creating a session between UE and SGW
Potential Applications
The technology described in the patent application can be applied in various cellular communication systems to efficiently manage network resources and establish connections between user equipment and network elements.
Problems Solved
1. Efficient selection of Packet Data Network Gateways (PGWs) based on DNS queries. 2. Streamlining the process of creating sessions between user equipment and Serving Gateways (SGWs).
Benefits
1. Improved network resource management. 2. Enhanced user experience through faster connection establishment. 3. Optimized utilization of network elements.
Potential Commercial Applications
Optimizing network resource allocation in cellular communication systems for improved performance and user satisfaction.
Possible Prior Art
One possible prior art could be the use of DNS queries to select network elements in cellular communication systems. Another could be methods of creating sessions between user equipment and network elements in a cellular network.
Unanswered Questions
How does this method handle network congestion?
The abstract does not provide information on how the method deals with network congestion and prioritizes connections during peak usage.
What security measures are in place to protect user data during the session creation process?
The abstract does not mention any security protocols or measures implemented to safeguard user data during the session creation process.
Original Abstract Submitted
a method of operation of a cellular communications system is disclosed. the method comprises: at a mme: receiving an attach request from a ue; sending a location update request to a hss; receiving a location update acknowledgement; sending, to a dns, a dns query request comprising an apn fqdn; receiving a dns query response comprising information that indicates candidate pgws that satisfy the dns query request and at least two pgws belonging to a same pgw set; selecting the first pgw; sending, to a sgw, a first create session request that comprises information that indicates the first pgw; receiving a first create session response; sending an attach accept to the ue; and at the sgw: receiving the first create session request from the mme; forwarding the first create session request to the first pgw; receiving the first create session response; and forwarding the first create session response to the mme.
