Abstract
A network element includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the network element to: designate a first user plane function, from among the plurality of user plane functions, as a designated broadcast forwarder from which to receive broadcast control traffic, and receive the broadcast control traffic forwarded from the first user plane function, from among the plurality of user plane functions.
Claims14
A network element having a control plane function configured to communicate with a plurality of user plane functions, the network element comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network element to establish a subscriber session on a first of the plurality of user plane functions in response to a request to establish the subscriber session, the subscriber session being established on the first of the plurality of user plane functions independent of whether the request to establish the subscriber session was received at the control plane function via the first of the plurality of user plane functions.
A network element having a control plane function configured to communicate with at least a first user plane function and a second user plane function, the network element comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network element to
- establish, at the first user plane function, a first fate sharing group including a plurality first subscriber sessions, the first fate sharing group being associated with a first MAC address and a first subscriber IP subnet,
- establish the first fate sharing group at the second user plane function,
- activate the first fate sharing group at the first user plane function from among the first user plane function and the second user plane function.
A network element having a user plane function between a first network and a second network, the network element comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network element to
- configure a first fate sharing group including a plurality of first subscriber sessions, the first fate sharing group associated with a first MAC address and a first subscriber IP subnet,
- configure a second fate sharing group including a plurality of second subscriber sessions, the second fate sharing group associated with a second MAC address and a second subscriber IP subnet, and the second fate sharing group being configured and active on another user plane function,
- activate the first fate sharing group at the user plane function, and
- deactivate the second fate sharing group at the user plane function.
A network element having a user plane function of a Control and User Plane Separation in Broadband Network Gateway between a first network entity and a second network entity, the network element comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network element to
- determine whether a MAC address received from the first network entity is present at the second network entity, the first network entity being one of a subscriber management module or a border gateway protocol entity, and the second network entity being another of the subscriber management module or the border gateway protocol entity, and
- update a forwarding database for the user plane function in response to determining that the MAC address is present at the second network entity.
