摘要： Systems and methods for call localization are provided. The call localization can be provided in a radio access network by detecting a call flow between mobile node such as user equipment (UE) served by the same radio access network device. For example, a gateway can detect a call localization opportunity and the call can be localized with an evolved nodeB (eNB). The method provides for efficient routing, reporting of billing information, lawful monitoring, and mobility if one or both user equipment leave the common eNB.

摘要： A method for allocating network addresses comprises providing an address pool comprising a plurality of network addresses and then dividing the address pool into a plurality of address sub-pool that comprise a unique subset of the network addresses of the address pool. Each of the sub-pools is available for use by any one of a plurality of routing devices of a network access server. The method then comprises receiving a request to assign a first network address to a first user, allocating a first address sub-pool of the plurality of address sub-pools to a first routing device of the plurality of routing devices and transmitting a first message to the other routing devices to indicate that the first address sub-pool has been allocated. The method additionally comprises assigning the first network address to the first user from the first address sub-pool and advertising an aggregate route for the first address sub-pool over a network.

摘要： Methods and systems for providing redundancy in servicing packet data communications within wireless mobile data networks are disclosed. More particularly, the method and system provide a redundant Home Agent with the ability to assume the role of the primary Home Agent in the event of a primary Home Agent network, software, or other failure. The redundancy allows the Home Agent services to remain functional even in the event of a failure of one of the Home Agents in the redundant group, which may be composed of one or more Home Agents. The Home Agents can use a service redundancy protocol which is composed of messages that are sent between the redundant group of Home Agents. The messages allow the Home Agents to, for example, back up call session information, check on the status of one another, and share priority information.

摘要： A high density network access server implements a tunneling protocol between a modem module and a route server module. PPP and routing control packets received from the PPP link are tunneled to the route server for processing. The IP data packet forwarding function for the network access server is distributed directly to the modem modules. The combination of distributed PPP processing and distributed IP data packet forwarding enables the capacity of the network access server to be scaled to orders of magnitude greater than previously known, to handle thousands or even tens of thousands of simultaneous data sessions.

摘要： Systems and methods for improved inter-technology handovers between wireless networks are disclosed, in which a source radio access network operates on a first technology and a target radio access network operates on a second technology, and both radio access networks are managed at a single packet serving gateway. A foreign agent receives a mobile subscriber identifier during a handover of a mobile device from the source radio access network to the target radio access network and sends the mobile subscriber identifier to the packet serving gateway, and the packet serving gateway locates at least one process instance running on the packet serving gateway that is routing existing packet flows to the mobile device based on the mobile subscriber identifier. The packet serving gateway then transfers control of the at least one process to a control process.

摘要： 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 a tracking area. The network device such as a mobility management entity (MME) can use a criteria or heuristic based implementation to provide a hierarchy for contacting a mobile device with a page. The criteria or heuristic based implementation can page a subset of the total number of cell sites in a tracking area and expand the subset after unsuccessful attempts to page the mobile device. The implementation can also be tailored to offer a range of options for page requests received by a network device, which can be based on such things as the application sending the page request.

摘要： The functionalities of one or more of a mobility management entity (MME), serving gateway (SGW), and packet data network gateway (PGW) can be provided in a single device on the network. In the access gateway different functional elements are implemented as services and they can be configured on the same device. For example, the SGW and PGW can be configured on the same device. When user equipment UE connects from a home network, it is possible for the MME to choose the same SGW and PGW. This combined SGW and PGW can implement a single session for the UE, thereby capable of providing a savings in resources, allowing additional capacity, and allowing reduced latency and increased throughput because fewer hops are made on the network. This session acts as a SGW on the ingress side and a PGW on the egress side of the access gateway.
