Systems and methods for intelligent network edge traffic and signaling management are disclosed. According to an aspect, a method for controlling network edge traffic may include receiving network traffic flow information from a network element. The method may also include determining a control command for a network edge element based on the network traffic flow information. Further, the method may include communicating the control command to a network for control of network traffic at an edge.

Methods, systems, and computer readable media for optimization of bearer resources for IMS roaming are disclosed. According to one aspect a system for optimization of bearer resources for IMS roaming includes a home media resource function controller module (HMRFC) for managing local media resources and for selecting a visited media resource function controller module (VMRFC) to provide media resources to a home subscriber that is roaming in the visited network ('visiting subscriber'), and a VMRFC for managing media resources within the visited network and for providing media resources to the visiting subscriber in response to a request to provide media resources to the visiting subscriber.

According to one aspect of the present invention there is provided a method of preparing second protocol data for transmitting over a first protocol network comprising the steps of compressing the data to be transmitted in accordance with the first protocol, to produced first protocol compressed data and encrypting the first protocol compressed data in accordance with the first protocol to produce first protocol compressed and encrypted data. The invention consists of a means for the client to indicate to the first hop proxy that it wishes S/MIME encryption to be applied to part of an outgoing message. The first hop proxy then applies this encryption on behalf of the client. The encryption is therefore applied after the message has traversed the end terminal link. On the first proxy link, the message is sent without S/MIME encryption and can therefore benefit from compression (before the first hop IPSEC encryption is applied). A second aspect of the invention allows the support of end-to-end compression to be negotiated between end devices so that SIP compression can be applied to data before it is encrypted using S/MIME by the end system.

Security over a network

It is desirable to allow mobile stations such as mobile telephones or cell phones to connect to a wireless cellular network even without the presence of a SIM card or other identification information. This is desirable for example, for access to emergency services. By configuring the mobile station to be able to populate replies to request for identification information during call set up which are received from the network, it is possible to avoid redesigning the network while providing 'SIM-less' access to the network.
