RESTORATION OF A PDN CONNECTION AT PGW FAILURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18511182 titled 'RESTORATION OF A PDN CONNECTION AT PGW FAILURE
Simplified Explanation
The method disclosed in the abstract involves the operation of a cellular communications system, including steps such as receiving an attach request from a UE, sending a location update request to a HSS, selecting a PGW, sending create session requests, and forwarding responses between network elements.
- Receiving attach request from a UE
- Sending location update request to a HSS
- Selecting a PGW based on DNS query response
- Sending create session requests between MME, SGW, and PGW
- Forwarding responses between network elements
Potential Applications
This technology can be applied in various cellular communication networks to efficiently manage network resources and establish connections for user equipment.
Problems Solved
1. Efficient selection of PGW based on DNS query response 2. Seamless establishment of connections between network elements
Benefits
1. Improved network efficiency 2. Enhanced user experience with faster connection setup
Potential Commercial Applications
"Optimizing Network Resource Allocation in Cellular Communications Systems"
Possible Prior Art
Prior art may include patents or publications related to network resource allocation, DNS query optimization, and session establishment in cellular networks.
Unanswered Questions
How does this method handle network congestion?
The abstract does not provide details on how the method addresses network congestion during the selection and establishment of network elements.
What security measures are in place to protect user data during these operations?
The abstract does not mention specific security measures implemented to safeguard user data during the various network operations described.
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.
