Bearer Contexts

GTP Bearer Contexts

A GTP (GPRS Tunneling Protocol) Bearer Context refers to the logical path created for user data transfer between the User Equipment (UE) and the network in mobile telecommunications.

Each bearer context is defined by a unique set of Quality of Service (QoS) parameters and characteristics to ensure proper delivery of services according to user or application needs.

Key Features:

• Unique Identification: Each GTP bearer is identified by the Tunnel Endpoint Identifier (TEID), along with the IP addresses of the GTP peers.

• QoS Parameters: Includes attributes such as priority, data rate, and delay tolerance, ensuring that data packets meet specific service requirements.

• Creation and Management: Bearers are dynamically created, modified, and deleted in response to network conditions and user activity.

• Separation of Control and User Plane: Facilitates efficient data routing and avoids congestion by keeping signaling and data transfer independent.

GTP Bearer Contexts are essential for maintaining a reliable and efficient data connection in 2G, 3G, and 4G networks.
