    Abstract: In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

    Abstract translation: 在用于在通信网络中建立通信的系统和方法中，网络服务提供商可以动态地为移动设备分配IP地址以节省IP地址资源。 网络服务提供商还可以实现网络地址转换，以进一步节省IP地址资源并提供改进的安全性。 如果请求者寻求获取移动设备的IP地址并且地址是本地地址，则系统确定移动设备是否具有将移动设备的IP地址与公共IP相关联的网络地址转换（NAT）绑定 地址。 如果移动设备没有NAT绑定，则系统创建NAT绑定，将移动设备的IP地址与公共IP地址相关联。

    Abstract: Various implementations disclosed herein enable programming user plane gateway controllers over enhanced N9 interfaces. In various implementations, a method of gateway controlling is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations the method includes determining, by a first packet gateway controller connected to a first session manager device, that a user equipment moved to a geographical area that is served by a second session manager device. In some implementations, the method includes receiving, by the first packet gateway device, a set of information for a second packet gateway device. In some implementations, the method includes transmitting, by the first packet gateway device, a session establishment request via a first network interface to the second packet gateway controller using segment routing via a second network interface.

    Abstract: A method is provided in one example and includes receiving a request from a first network element associated with a first network for establishing a first communication session between the first network element to a first user device associated with a second network. The request includes a first user identifier used to identify a first user associated with the first user device within the first network. The method further includes translating the first user identifier to a second user identifier in which the second user identifier is used to identify the first user within the second network. The method still further includes sending a first query including the second user identifier to a second network element, and receiving a first response message including quality of service information indicated by a policy associated with the second user identifier.

    Abstract: A method is provided in one example and includes receiving at least one first input indicating at least one network condition associated with a first user device having a user associated therewith. The first user device has a first bearer channel established between the first user device and a gateway, and the first bearer channel has a first quality of service level. The method further includes determining whether to modify the first user device to a second quality of service level based upon the received at least one first input, and sending a first request to a first network element instructing the first network element to modify the first user device to the second quality of service level.

    Abstract: This disclosure relates to systems and methods for paging devices in a communication network. A network device providing mobility management through control messaging can be assigned a number of cell sites in multiple tracking areas. The network device such as a mobility management entity (MME) can use a subscriber-aware implementation to provide a hierarchy for contacting a mobile device with a page. The subscriber-aware implementation can be tailored to analyze subscriber activity such as frequency and timing, to page a subset of the total number of cell sites in multiple tracking areas based on the subscriber activity, and to expand the subset after unsuccessful attempts to page the mobile device.
