In one embodiment, while being connected to the network, a security issue may be detected and associated with the device. The device may be placed on a blacklist for the security issue. The blacklist is a list that is used to deny service for the device when it attempts to connect. Thus, the device is disconnected from the network. Identification information for the device is added to the blacklist at the authentication server. If the device attempts to reconnect to the network, the request is received at the authentication server. The authentication server can then check the blacklist and deny the request for access to the network if the identification information is on the blacklist. This denial is determined without sending the request to the HLR. Accordingly, the HLR is protected in that requests from a device that may be considered a security issue are not sent to the HLR.

In one embodiment, techniques for authorizing a mobile device are provided. A registration request is received for the mobile device. The registration request may include location identifier information. For example, a cell ID may be provided. Static location information is then determined based on the location identifier information. The static location information may be spatial coordinates. The registration request is then authorized based on the static location information. For example, a cell ID may be received and then spatial coordinates may be determined based on the cell ID. The registration request is then authorized based on the spatial coordinates. A response to the registration request is then sent.

An example method is provided and includes receiving a packet associated with a flow, determining a tunnel identifier for the flow, and determining a flow identifier for the flow. The method includes associating the flow identifier and the tunnel identifier to an Internet protocol (IP) address to generate a binding to be used for a network address and port translation (NAPT). In other embodiments, a routing decision is executed based on the binding between the identifiers and the IP address. The flow identifier can be a context identifier (CID), and the tunnel identifier can be a softwire tunnel ID. In yet other embodiments, the packet can be tagged as part of an encapsulation operation, which includes providing information about a network location at which the network address and port translation is to be executed.

In one embodiment, a network application may offload stateful operations to a user-plane application. In one embodiment, the network application receives state information for a user device. The network application then sends the state information to a user-plane application, which can maintain the state information. The network application may then offload a stateful operation to the user-plane application. For example, the network application may have the user-plane application perform stateful operations. Also, the network application may use the state information maintained at the user-plane application for error recovery after the network application fails. For example, the network application may recover the state information from the user-plane application after failure.

Techniques and systems for server farm load balancing and resource allocation are disclosed. In one embodiment, a method of load balancing can include: arranging servers into service groups; receiving an access request with information related to a differentiation between the service groups; selecting one of the service groups based on a mapping comparison to the information; and selecting one of the servers within the selected service group based on a hardware utilization comparison. The servers can include GPRS (General Packet Radio Service) Gateway Support Node (GGSN) or Remote Authentication Dial In User Service (RADIUS) servers, for example. The information can include an Access Point Name (APN) or Calling Station ID, for example.

Systems and methods are provided to facilitate efficient routing of unlicensed mobile access (UMA) communications. In one implementation, a method of providing a communication link between a first mobile station and a second mobile station through a customer premises equipment (CPE) device includes intercepting a call setup request provided by the first mobile station and received at a security gateway of the CPE device. An address associated with the second mobile station may be extracted from the call setup request and the address may be compared with a plurality of records maintained by the CPE device. A call setup request may be forwarded to the second mobile station if the address corresponds to at least one of the records. The first and second mobile stations may be in communication with the CPE device over a wireless local access network (WLAN) in accordance with an unlicensed mobile communication standard.

Systems and/or methods of selectively terminating security in mobile networks are presented. User equipment (UE) can specify cipher termination location capabilities for encrypting/decrypting data packets to a base station in a mobile network. The mobile network can subsequently determine at which node in the network to terminate the cipher in part according to the capabilities provided and deliver the determined location to the UE. The determined cipher termination location can be provided in response to a request to initiate communications, the initial request can specify the capabilities. The UE can utilize the location to support disparate types of networks and to intelligently deal with hand-offs and other functions of the mobile network.

In a cellular mobile telephone system, a mobile station (4d, 4e) requests allocation of a traffic channel by sending a request in a random access channel. Where there is a significant path length difference between locations in a cell and a network antenna, for instance on a satellite (3), not all of the available TDMA slots are used for random access signals. Instead, gaps of one to three time slots are left between valid random access time slots (103, 104) to avoid collision between random access bursts arriving at the network antenna along paths of different lengths.

A system for efficiently reauthenticating a client of a network. In a specific embodiment, the system includes an authentication server and a Security GateWay (SGW) in communication with the client. The SGW includes reauthentication information associated with the client. In a more specific embodiment, the authentication server includes an Authentication, Authorization, and Accounting (AAA) server. The SGW further includes one or more routines for employing the reauthentication information to reauthenticate the client. The AAA server performs initial authentication of the client to enable client access to the network, which yields the reauthentication information. The reauthentication information includes one or more keys and/or counters, such as an authorization key, an encryption key, and a master key, which is/are predetermined by the AAA server.
