Overload control for trusted WLAN access to EPC
In an embodiment, a method is provided for overload control for Trusted WLAN access to EPC, comprising: when rejecting a request for an UE in single connection mode (SCM) for an authenticated and authorized user, the network signalling a back-off time to the UE for the requested APN when congestion control is active for the APN, upon reception of the back-off time, the UE not initiating new request for the congested APN, for the duration of the back-off time.
1. An apparatus comprising:
at least, one memory configured to store computer-readable instructions; and
at least one processor configured to execute the computer-readable instructions to cause the apparatus to
request establishment of a packet data network connection via a trusted wireless local area network access to an evolved packet core network, in a single connection mode wherein a single connection at a time is supported via the trusted wireless local area access network,
receive, from an authentication, authorization, and accounting server, a response message including a failure cause due to congestion and a hack-off time, and
not initiate a new request for said establishment of a packet data network connection, for a duration of the back-off time.
2. The apparatus according to claim 1 , wherein the request is for a requested access point name, and the back-off time is for the requested access point name.
3. A method comprising:
requesting establishment of a packet data network connection via a trusted wireless local area network access to an evolved packet core network, in a single connection mode wherein a single connection at a time is supported via the trusted wireless local area network access network;
receiving, from an authentication, authorization, and accounting server, a response message including a failure cause due to congestion and a back-off time; and
not initiating a new request for said establishment of a packet data network connection, for a duration of the back-off time.
4. The method according to claim 3 , wherein the request is for a requested access point name, and the back-off time is for the requested access point name.
5. An apparatus comprising:
at least one memory configured to store computer-readable instructions; and
at least one processor configured to execute the computer-readable instructions to cause the apparatus to
receive overload information from a packet data network gateway of an evolved packet core network for a user equipment request for access to said evolved packet core network via a trusted wireless local area network access network, for a connection to a packet data network, in a single connection mode wherein a single connection at a time is supported via the trusted wireless local area access network, and
reject said request and signal to an authentication, authorization, and accounting server a failure cause due to congestion and a back-off time to signal to the user equipment to cause the user equipment not to initiate a new request for a duration of the back-off time.
6. The apparatus according to claim 5 , wherein the request is for a requested access point name, and the back-off time is for the requested access point name.
