Embodiment Construction

[0035] The following description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the invention is defined by the appended claims. For simplicity, the following embodiments are discussed with respect to the terminology and structures of the 3GPP architecture. However, the embodiments discussed next are not limited to these systems, but are applicable to other existing systems.

[0036] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the sam...

Abstract

A system, computer readable medium and method for providing to a user device (20) location information of a data device that provides a specific asset, where the user device (20) is present in a network (32) that includes at least a serving node (36) and an address of the user device (20) is indicative of a gateway node (35) that is different from the serving node (36). The method includes receiving at the serving node (36) a first message from the user device (20), the first message including a request for the specific asset; sending the first message from the serving node (36) to the gateway node (35); receiving at the serving node (36) a second message from the gateway node (35), the second message including a first location of a first data device (44) that provides the specific asset; modifying at the serving node (36) the second message to include an indication about a second location of a second data device (46) that provides the specific asset, where the first location is different from the second location; and sending the modified second message including the second location to the user device (20) for accessing the specific asset.

Description

technical field [0001] The present invention relates generally to systems, software, and methods, and more specifically, to mechanisms and techniques for redirecting user devices to more appropriate data sources. Background technique [0002] Over the past few years, access to the Internet has enabled more and more people to use their computers or mobile phones or other devices (user devices) to download content, services, etc. from various service providers in order to watch movies, listen to songs, read the news, etc. As such, content delivery networks (CDNs) have become prevalent in the current Internet environment. CDNs provide mechanisms and network infrastructure that enable service providers to improve the accessibility of content to clients. FIG. 1 illustrates a system 10 with a client device 20 connected to a service provider 30 to request content from a CDN 40 . [0003] Content may include web pages (and / or individual objects, such as images on web pages), vide...
