A method is provided in one example embodiment and includes receiving a request for a service flow over a wireless link, where the request specifies resource requirements; dynamically reserving bandwidth for the resource requirements in a backhaul link; and mapping a packet received over the wireless link to the backhaul link based on an identification element associated with the packet and the service flow.

A method is provided in one example embodiment and includes receiving a plurality of status signals, for a plurality of radio links, at a microwave device; detecting a bandwidth anomaly based on the status signals; and communicating a quality of service (QoS) control signal, which is based on the bandwidth anomaly, to a gateway coupled to at least one of the radio links.

In one embodiment, a security gateway receives an IPSec Initiation (IPSec INIT) request from a client. The security gateway may communicate with a AAA server to authenticate the client. After authentication, the security gateway intercepts a URR Discovery request from the client. The security gateway determines registration information for a response to the registration request. The registration information may be information on where the client can locate a D-GANC. A response is generated using the determined information and sent to the client. The response to the discovery request is performed without communicating with a P-GANC. Accordingly, a security gateway is used to authenticate the client and also to respond to the discovery request. This does not require that a P-GANC function be deployed in a network. Thus, cost and processing power may be saved.

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.

An apparatus for providing connectivity is provided that includes a mobility server operable to coordinate a communication session between a first and a second end-user device. The first end-user device is associated with a first call leg and the second end-user device is associated with a second call leg. A handoff is executed in transferring the communication session from the first end-user device to the second end-user device. In more particular embodiments, the mobility server is operable to receive signal strength information from the first end-user device and to execute the handoff based on the signal strength information. In addition, the handoff is executed based on an end-user preference that is provided in a subscription that is accessed by the mobility server.

An apparatus for charging in a network environment is provided that includes an access gateway encapsulation/decapsulation element operable to establish one or more packet data protocol (PDP) links on behalf of an end user and to perform encapsulation and decapsulation operations for one or more of the links associated with the end user. The access gateway encapsulation/decapsulation element is further operable to interface with a client services packet gateway (CSPG) that is operable to provide enhanced packet processing for the end user for requested information. The apparatus also includes an access gateway policy element operable to interface with the CSPG. The access gateway encapsulation/decapsulation element and the access gateway policy element cooperate to use one or more inter-module headers in order to coordinate the enhanced packet processing for one or more communication flows associated with the end user.

In one embodiment, a load balancer receives a message from a tunnel termination gateway (TTG) associated with a mobile device. The load balancer may receive messages from a plurality of TTGs. A gateway node in a plurality of gateway nodes in which to send the message is determined. The load balancer then assigns a NSAPI for use by the gateway node. For example, the NSAPI may be associated with a tunnel that is generated between the TTG and GGSN. The load balancer ensures that the assigned NSAPI is not currently in use at the gateway node. Thus, no overlapping of NSAPIs may occur even though the load balancer is processing messages from multiple TTGs for multiple gateway nodes.

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.

A method for assisting in a handover is provided that includes utilizing a link between a centralized access controller (CAC) and customer premises equipment (CPE) to facilitate a communication session involving a mobile station. The method also includes rejecting a handover from a public network to a cell controlled by the CAC after recognizing, in advance, that sufficient resources are unavailable for supporting a channel to be employed for the handover.
摘要:
In a satellite mobile telecommunications system based on the GSM standard, and using a TDMA frame structure, discontinuous transmission (DTX) mode is used to take advantage of the substantial silences which occur during normal speech. In this mode, traffic channel (TCH) data is not sent, but control of the link between a ground station and a user terminal is maintained by sending control channel data bursts (SACCH) together with silence descriptor (SID) frames. To avoid high peak to mean values of transmission power at the satellite, the emission time of the bursts is controlled so as to be uniform over the available sending opportunities. Conventional techniques for doing this cannot be used in a system which includes diversity operation. Therefore, the burst transmission time at the ground station is set in dependence on a reference provided by the user terminal which is a modified version of the reference generated for contention resolution of random access requests.
