摘要： The authorized IP addresses configured at components in an IMS network may become out of sync with a first pool of IP addresses provided by a core network to UEs. This may result in emergency communications being received at the IMS network from a UE using a first IP address of the first pool of IP addresses that is not recognized by the IMS network. A session management component of the core network may automatically assign a second IP address from a second pool of IP addresses based on determining the session management component has not received an update notification from the IMS network within a threshold time (e.g., 500 milliseconds, 1000 milliseconds, etc.) from transmitting a request to establish a packet data communications session to the IMS network using the first IP address. The IMS network may then receive packets from the second IP address.

摘要： The disclosed system includes a first gateway of a first type configured to receive wireless packets from a core network node, and a second gateway of a second type colocated with the first gateway and configured to transmit at least a portion of the wireless packets to a network. The first gateway is configured with a first internet address that identifies the second gateway and a second internet address that identifies a third gateway of the second type. The first gateway is configured to transmit a first portion of the wireless packets to the second gateway based on the first internet address and transmit a second portion of the wireless packets to the third gateway based on the second internet address. The second gateway is configured with a third internet address that identifies the second gateway.
