Definitions
- the present invention relates to content retrieval services provided in a radio access network and more particularly to the caching of retrieved content in a radio access network.
- the radio access network provides for the foundation of modern cellular telephony.
- the RAN functions to join different end user mobile devices to a core network (CN) such that individuals can enjoy telephonic and data communications wirelessly within a geographic area covered by the various base stations of the radio access network.
- CN core network
- the RAN provides the requisite infrastructure to pass both voice and data traffic from the over-the-air medium to both the terrestrial circuit switched communication network and the packet switched data communications network inclusive of the global Internet.
- the RAN generally includes multiple different radio network controllers (RNC) each managing a set of base stations providing wireless connectivity to a geographic cell.
- RNC radio network controllers
- the entirety of the different RNCs of the RAN are linked to what is known as the cellular data core or CN through a gateway known as the serving generalized radio packet service node (SGSN).
- SGSN serving generalized radio packet service node
- the CN provides various services to customers who are connected by the RAN.
- One of the main functions is to route calls across the public switched telephone network (PSTN).
- PSTN public switched telephone network

- CDN content delivery network
- the CN includes a gateway known as the gateway GPRS service node (GGSN).
- GGSN gateway GPRS service node
- the typical CDN can provide for advanced content delivery services such as content caching and content filtering.
- Content caching refers to the intermediate temporary storage of previously retrieved content under the assumption that a temporally proximate subsequent request for the content can be satisfied from temporary storage rather than repeating a more time consuming request for content in the CDN.
- content filtering refers to the restriction of the delivery of requested content when the content meets a particular profile such as being published by a particular source or incorporating particular subject matter.
- TCP transport control protocol
- a method for content caching with remote filtering services in a RAN can include receiving a response to a request from an end user device wirelessly coupled to a base station of the RAN, marking the response as uncacheable, and routing the response to the base station over a data communications network.
- the response can be received in an RNC of the RAN.
- the process of marking the response as uncacheable can depend upon the evaluation of a policy with respect to the response.
- marking the response as uncacheable can include annotating a hypertext transfer protocol (HTTP) header of the response to indicate that the response is not to be cached in the base station.
- HTTP hypertext transfer protocol
- a RAN based data processing system can be configured for content caching with remote filtering services.
- the system can include a base station comprising an antenna, a receiver, a transmitter, a processor, a local cache, and a network interface to a data communications network.
- the system also can include an RNC coupled to the base station over the data communications network and a caching module disposed in the base station and coupled to a cache.
- the system can include a filtering service executing in the RNC.
- the service can include program code enabled to receive a data request from the base station on behalf of an end user device, to route the request to a content server in a computer communications network through a coupled CN, to receive a response to the request, to determine whether or not the response is cacheable according to a policy, to mark the response as uncacheable if determined to be uncacheable, and to forward the response to the base station.
- the present invention provides a method for content caching with remote filtering services in a radio access network, RAN, the method comprising:
- the present invention provides a radio access network, RAN, based data processing system configured for content caching with remote filtering services, the system comprising: a base station comprising an antenna, a receiver, a transmitter, a processor, a local cache, and a network interface to a data communications network; a radio network controller, RNC, coupled to the base station over the data communications network; a caching module disposed in the base station and coupled to a cache; and, a filtering service executing in the RNC, the service comprising:

- RAN radio access network
- the present invention provides a computer program stored on a computer readable medium and loadable into the internal memory of a digital computer, comprising software code portions, when said program is run on a computer, for performing the steps of the invention. Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
- Figure 1 is a pictorial illustration of a process for content caching with remote filtering services in a RAN, in accordance with a preferred embodiment of the present invention
- FIG. 2 is a schematic illustration of a RAN based data processing system configured for content caching with remote filtering services, in accordance with a preferred embodiment of the present invention.
- Figure 3 is a flow chart illustrating a process for content caching with remote filtering services in a RAN in accordance with a preferred embodiment of the present invention.
- Embodiments of the invention provide for a method, system and computer program product for content caching with remote filtering services in a RAN.
- content requests received in an RNC from different base stations coupled to the RNC can be routed through a CN to addressed content providers in a content distribution network such as the global Internet.
- Response received for the requests can be compared to a filtering policy to determine whether or not the individual responses are cacheable.
- the filtering policy can specify content uncacheable according to age of the content, type of the content, the source of the content, or constituent components of the content.
- the non-cacheable response can be marked as such and forwarded to a base station from which a corresponding request had been received.
- a caching module in the base station in turn, can cache only those responses not marked uncacheable. In this way, the caching function can remain distributed in the respective base stations while maintaining the filtering service in the RNC.
- Figure 1 pictorially depicts a process for content caching with remote filtering services in a RAN.
- a cellular telecommunications network can be provided to include different base stations 120 arranged to provide wireless telephonic access to different end user devices 110 for the PSTN 140.
- Clusters of the base stations 120 can be communicatively linked to a common RNC 130 that in turn can be coupled to a CN 150 thus forming a RAN.
- the CN 150 can include both a SGSN 160A acting as a gateway for traffic between the CN 150, the PSTN 140 and each RNC 130, and also a GGSN 160B acting as a gateway between the CN 150 and the data communications network 100— typically the global Internet.
- the CN 150 itself can support a number of content services 170 as is well known in the art.
- a data processing system for content filtering 190 A can be disposed in the RNC 130 and can be configured for communicative coupling to different content caches 190B each executing in respectively different base stations 120.
- the data processing system 190A can include program code that when executes in the data processing system, processes content 190C retrieved in response to a content request originating from an end user device 110 by way of a corresponding base station 120, from a content server 180 on the data
- the data processing system 190 A can filter the content 190C according to a filtering policy specifying whether or not particular content 190C is to be deemed cacheable. For content 190C deemed uncacheable, the data processing system 190 A can mark the content 190C as such, for example by embedding a notation in an HTTP header of the content 190C. Thereafter, the data processing system 190 A can route the content 190C to the corresponding base station 120 for return to the end user device 110 and for caching by the content cache 190B if the content 190C has not be marked as uncacheable.
- Figure 2 is a schematic illustration of a RAN based data processing system configured for content caching with remote filtering in a packet data network such as a 2.5G or 3G network.
- the system can include a base station 200A coupled to an RNC 200B over a communications network 250, commonly an IP network or an asynchronous transfer mode (ATM) network.
- the base station 200 A can include a receiver/transmitter 230 receiving over-the-air communications from different end user devices within transmission range of the base station 200A by way of antenna 265, and routing the same to the RNC 200B by way of a network interface 210.
- a processor 240 can be provided to perform computational processing on received data as the data is placed in memory 220.
- a caching module 280 coupled to a content cache 275 can execute by the processor 240 of the base station 200A.
- the caching module 280 can perform caching of cacheable content in the cache 275 for content received in the base station 200A in response to requests from coupled end user devices.
- the RNC 200B can include a host computer 260 with at least one processor and memory supporting the execution of an operating system 270.
- the operating system 270 in turn can host the execution of a content filtering service 280.
- the content filtering service 280 can include program code that when executed in the operating system 270, can receive responses to requests from over the data communications network 250 and apply a policy 285 to those responses to determine whether or not the responses are cacheable.
- the program code of the content filtering service 280 can mark those uncacheable responses as such—for example by annotating a header to the responses indicating that the responses are not be cached by the caching module 280 in the base station 200A.
- Figure 3 is a flow chart illustrating a process for content caching with remote filtering services in a RAN.
- a content request can be received from a base station on behalf of an end user device wirelessly accessing the base station.
- the request can be routed onto the CN for ultimate processing by a content provider on the global Internet.
- a response to the request can be received from over the CN and in block 340, a policy can be applied to the response.
- the policy can specify whether or not content in the response is to be cached or marked uncacheable. For instance, the policy can set forth that content is not be cached based upon the age of the content, the constituency of the content, or the source of the content, to name only a few criteria.
- decision block 350 if the policy once applied results in the content having been determined to be cacheable, the response can be routed to the base station for delivery to the end user device and caching in the base station at the discretion of the caching module of the base station. However, if in decision block 350, it is determined according to the policy that the content is not cacheable, in block 370, the response can be marked as non-cacheable before the content is returned in the response to the base station in block 360 along with the marking of non-cacheability.
