Abstract
Examples provided herein establish a GTP session between a base station and a gateway. A session establishing request is received in response to an attach request from a wireless terminal to the base station, and a gateway located within an edge site is selected based on the session establishing request. The session establishing request is edited to include information designating the gateway and transmitted to the gateway.
Claims21
A method comprising:
- in response to receipt by a first base station of an attach request from a wireless terminal associated with terminal-related information, receiving, by a server, a session establishing request from a network management device (MME);
- acquiring, by the server, a list of serving and packet data network gateway (S/PGW) candidates;
- selecting, by the server, a serving and packet data network gateway (S/PGW) located at an edge site from the list of serving and packet data network gateway (S/PGW) candidates based on the terminal-related information and base station information included in the session establishing request;
- editing, by the server, the session establishing request to include a designation of the serving and packet data network gateway (S/PGW), wherein the session establishing request is edited at a Fully Qualified Tunnel End Point Identifier (F-TEID) field to include the designation of the serving and packet data network gateway (S/PGW);
- in response to transferring the edited request to the serving and packet data network gateway (S/PGW), receiving, by the server, a response from the serving and packet data network gateway (S/PGW), wherein an internet protocol (IP) address of an interface with the serving and packet data network gateway (S/PGW) is set in the F-TEID field;
- and
- transferring, by the server, the response to the network management device (MME) such that the response establishes a General Packet Radio Service (GTP) session between the first base station and the serving and packet data network gateway (S/PGW).
An apparatus comprising:
- a receiver that, in response to receipt by a first base station of an attach request from a wireless terminal, receives a session establishing request from a network management device (MME);
- a controller that:
- acquires a list of serving and packet data network gateway (S/PGW) candidates;
- selects a serving and packet data network gateway (S/PGW) located within an edge site from the list of serving and packet data network gateway (S/PGW) candidates based on the session establishing request;
- and
- edits the session establishing request to include information designating the serving and packet data network gateway (S/PGW), wherein the session establishing request is edited at a Fully Qualified Tunnel End Point Identifier (F-TEID) field to include the information designating the serving and packet data network gateway (S/PGW);
- a transmitter that transmits the edited session establishing request to the serving and packet data network gateway (S/PGW);
- the receiver that receives a response from the serving and packet data network gateway (S/PGW), wherein an internet protocol (IP) address of an interface with the serving and packet data network gateway (S/PGW) is set in the F-TEID field;
- and
- the transmitter that transmits the received session establishing response for establishing a General Packet Radio Service (GPRS) Tunneling Protocol (GTP) session between the first base station and the serving and packet data network gateway (S/PGW).
A non-transitory machine-readable storage medium encoded with instructions executable by a processor, that when executed causes a computing device to:
- receive a session establishing request in response to receipt by a first base station of an attach request from a wireless terminal;
- acquire a list of serving and packet data network gateway (S/PGW) candidates;
- select a serving and packet data network gateway (S/PGW) located at an edge site from the list of serving and packet data network gateway (S/PGW) candidates based on the received session establishing request;
- edit the session establishing request to include a designation of the serving and packet data network gateway (S/PGW), wherein the session establishing request is edited at a Fully Qualified Tunnel End Point Identifier (F-TEID) field to include the designation of the serving and packet data network gateway (S/PGW);
- transfer the edited session establishing request to the serving and packet data network gateway (S/PGW), wherein an internet protocol (IP) address of an interface with the serving and packet data network gateway (S/PGW) is set in the F-TEID field;
- receive a session establishing response from the serving and packet data network gateway (S/PGW);
- and
- transfer the received session establishing response for establishing a GTP session between the first base station and the serving and packet data network gateway (S/PGW).
