摘要： A wireless communication system constructed according to the present invention assigns each serviced mobile unit to a serving mobile switching center to minimize mobility management overhead and to equalize loading among a plurality of mobile switching centers. The wireless communication system includes the plurality of mobile switching centers and a base station system which includes a plurality of base station controllers, each of which couples to a plurality of base stations. A plurality of mobile units served by the system are assigned to the mobile switching centers so that loading is equalized. In one particular construction of the wireless communication system, a dispatching switch couples the base station system to the plurality of mobile switching centers and performs the assignments of the mobile units. In an example of operation, upon attachment of a mobile unit, the dispatching switch determines loading of each of the mobile switching centers. Then, based upon the loading, the dispatching switch assigns the mobile unit to one of the mobile switching centers, the "serving" mobile switching center. During subsequent calls, the dispatching switch establishes a transparent path between a base station controller servicing the call and the serving mobile switching center. Thus, once the serving mobile switching center is determined, operation is transparent to the serving base station controller and the serving mobile switching center. In another particular construction, each of the base station controllers couple to each of the mobile switching centers via a network. In such case, each of the base station controllers and each of the mobile switching centers includes additional equipment which performs at least a portion of the operations of the dispatching switch. The network may be dissimilar to a conventional data structure supported by the wireless communication system. In still another implementation, a signaling message router function routes signaling messages to the serving mobile switching center by using the mobile unit's temporary identification number (as assigned by the serving mobile switching center). The signaling message router function may be implemented in the network coupling the base station sub-system with the mobile switching center (in a message router), in the base station controller or in the mobile switching center.

摘要： The present disclosure relates generally to systems and methods for protecting emergency response services in telecommunications systems from attack. In one example, a system may include a network, a token generator, and a token validator. The network may be configured to communicate with a client via a network interface. The token generator is coupled to the network and configured to generate at least one token based on information associated with the client. The token contains sufficient information for the network to independently validate the client when an emergency response service request is sent by the client to the network. The token validator is coupled to the network and configured to perform a validation process on the token when the token is sent by the client to the network over the network interface. The network is configured to connect the emergency response service request only if the token is validated.

摘要： A method for preventing service disruption for a device in a network is provided. The method includes populating a filter list with an IP address declared to be valid for a server in the network and populating a rainy day list with an IP address discovered to be valid for the server. The method also includes requesting a DNS server to resolve a server domain name to a server IP address. When no response to the request is received, an IP address on the rainy day list is used to attempt to contact the server. When a response is received, the received IP address is compared to an IP address on the filter list or the rainy day list. When the received IP address matches an IP addresses on the filter list or the rainy day list, the received IP address is used to contact the server.

摘要： The present disclosure relates generally to systems and methods for providing secure network access in fixed mobile converged telecommunications systems. In one example, a method includes establishing, by a fixed access device, a connection with a mobile terminal over an air interface. The fixed access device may also establish a limited channel with a service provider network via a broadband interface. The limited channel is restricted to messages meeting one or more criterion. The mobile terminal may be authenticated with the service provider network via the limited channel using authentication information associated with the mobile terminal, and the service provider network has a preexisting relationship with the mobile terminal. A secure channel may be established between the fixed access device and the service provider network after the mobile terminal is authenticated. The secure channel may enable the mobile terminal to communicate with the service provider network using messages not meeting the criterion.

The server includes a controller configured to select a desired response profile for a plurality of broadcast client devices from a plurality of response profiles based upon current resource conditions and to include a prescribed response behavior for the client in the broadcast message. The broadcast message includes a response control field providing information regarding the desired response profile. The client devices include a receiver configured to receive the broadcast message. The client devices also include a controller configured to decode the control field in the broadcast message to determine the response behavior and respond to the broadcast message as prescribed by the server.
