Abstract
A gateway device of a mobile packet core network matches (S31) data packets flowing to/from the mobile packet core network, using a filter, and terminates (S33) a session in accordance with an action for the filter when a data packet of the session, which flows to/from the mobile packet core network, matches the filter (S32).
Claims12
A method comprising:
- detecting that there is no connectivity to a mobile packet data network due to a link or route failure;
- in response to the detecting, enabling and activating a rule in a gateway device of the mobile packet core network, with a filter that includes at least one of a specific service, a specific application, a specific protocol, an address range of user equipments that are known to have a connection to the mobile packet data network, or a packet destination address, wherein the rule is provided by a policy and charging rules function;
- detecting, by the gateway device, when a data packet flowing to or from the mobile packet core network matches the filter;
- terminating, by the gateway device a session when a data packet of the session, which flows to or from the mobile packet core network, matches the filter;
- maintaining, by the gateway device, the session when the session does not send any data during a period when there is no connectivity to the mobile packet data network;
- and
- establishing, in association with at least one session that was previously terminated, at least one new session via the gateway device or another gateway device.

A gateway device of a mobile packet core network, comprising:
- a processor;
- and
- a memory, wherein the processor and the memory are configured to cause the gateway device at least to:
- enable and activate a rule with a filter, wherein the rule is provided by a policy and charging rules function;
- detect when a data packet flowing to or from the mobile packet core network matches the filter, the filter includes at least one of a specific service, a specific application, a specific protocol, an address range of user equipments that are known to have connection to the mobile packet data network, or a packet destination address;
- terminate a session when the data packet of the session, which flows to or from the mobile packet core network, matches the filter;
- maintain the session when the session does not send any data during a period when there is no connectivity to the mobile packet data network;
- and
- establish, in association with at least one session that was previously terminated, at least one new session via the gateway device or another gateway device.

A non-transitory computer-readable storage medium having stored thereon a computer program product including a program for a processor of a gateway device of a mobile packet core network, comprising software code portions for performing, when the program is run on the processor:
- enabling and activing a rule with a filter, wherein the rule is provided by a policy and charging rules function;
- detecting when a data packet flowing to or from the mobile packet core network matches a filter, the filter including at least one of a specific service, a specific application, a specific protocol, an address range of user equipments that are known to have connection to the mobile packet data network, or a packet destination address;
- terminating a session when the data packet of the session, which flows to or from the mobile packet core network, matches the filter;
- maintaining a session when the session does not send any data during a period when there is no connectivity to the mobile packet data network;
- establishing, in association with at least one session that was previously terminated, at least one new session via the gateway device or another gateway device.
