Description

CACHE STORAGE OF CONTENT WITH REMOTE LOAD SERVICES IN A RADIO ACCESS NETWORK TECHNICAL FIELD The present invention is concerned with content retrieval services provided in a radio access network and more particularly with caching the content retrieved in a radio access network.
BACKGROUND OF THE INVENTION The radio access network (RAN) provides the foundation of modern cellular telephony. The RAN works to link different mobile end-user devices to a core network or central network (CN) in such a way that individuals can enjoy telephone and data communications wirelessly within a geographic area covered by the various base locations of the network of radio access. Generally speaking, the RAN provides the infrastructure required to pass both the voice traffic and data from the medium in the air to both the communication network communicated by terrestrial circuits and the data communication network communicated by the inclusive global internet packages .
In the present, several standards have been implemented in relation to the RAN. Examples include the global system for mobile communications (GSM), the universal mobile communications system (UMTS) and the "Edge" RA of GSM (GERAN). The RAN generally includes multiple different radio network controllers (RNCs) each operating a set of base stations that provide wireless connectivity to a geographic cell. All the different RNCs of the RAN are linked to what is known as the cellular data core or CN by means of a gate known as the generalized service radio packet service node (SGSN). The NC provides several services to clients that are connected by the RAN. One of the main functions is to route calls through the public connected telephone network (PSTN). Another is to wrap data packets in an internet protocol (IP) network such as global internet such that end users of the RAN can access services provided by a content delivery network (CDN). For that purpose, the CN includes a gate known as the gate GPRS service node (GGSN).
The typical CDN can provide advanced content delivery services such as content caching and content filtering. Content caching refers to intermediate temporary storage of content previously recovered under the supervision that a subsequent temporary request for content can be satisfied from temporary storage instead of repeating a request that consumes more time for content in the CDN . In contrast, content filtering refers to the restriction of the delivery of the requested content when the content satisfies a particular profile such as being published by a particular source or incorporating particular material. In both instances, the packet processing required to perform advanced content services often demands that those services be provided within the CN where the communications protocol used in the CN is consistent with that of global internet-that is, the control protocol transport (TCP) over IP.
Still, some have suggested placing media for content services such as content caching and content filtering within the RANs. In this regard, Patent Application Publication 20100034089 of Kovvali et al., Suggests the placement of content caching services within the RAN and the removal of TCP / IP loads from the RAN protocol specific to the RAN. However, the placement of content services such as caching and filtering even closer to the end user within the various base stations is undesirable since this requires hardening of computing devices that support the content devices due to the medium physical environment of the base station. As such, when the content services are performed at the base station, only a minimum computing device is provided to handle most of the most basic content services. However, it is often desirable to make more than just the most basic content services. For example, in many instances it is desirable to perform upload services for the content services provided to the end users. To the extent that freight services require more than the most basic computing device, freight services together with the corresponding content services are provided jointly in the RAN as a matter of convenience.
Accordingly, there is a need in the art to deal with the problems mentioned above.
BRIEF DESCRIPTION OF THE INVENTION The embodiments of the present invention address deficiencies in the art with respect to content services in a RAN and provide a novel and non-obvious method, computer program and product product for caching content with remote loading services in a RAN. In one embodiment of the invention, a method for caching content with remote load services in a RAN has been claimed. The method includes receiving a data request from an end-user device in a base station of a RAN and routing the request to a packet-switched data communications network of the base station by means of a core network or central network arranged between the RAN and the data communications network. The method also includes receiving a response to the request at the base station, caching the response in a local cache memory of the base station, and sending a response to the end user device. Finally, the method includes transmitting characteristic data of the response to a remote load service external to the base station but within the RAN, for example a size of the response, a size of the request or both. In one aspect of the mode, the transmission of the characteristic data of the response to a remote load service may include first batching the characteristic data of the response with other data characteristic of other responses to other requests of other end-user devices. which communicate with the base station and subsequently transmit the data by batch to the remote loading service.
In another embodiment of the invention, a RAN-based data processing system may be configured to store the contained cache with remote loading services. The system may include a base station that includes an antenna, a receiver, a transmitter, a processor, a local cache memory and a network interface to a data communications network. The system may also include an R C coupled to the base station over the data communications network. The system may also further include a charging service that executes in registry of a host computer registration charges for data service provided in the RAN. Finally, the system can include a cached storage with the remote loading module executed by the processor of the base station. The module may include program codes enabled to receive a data request from an end user device, to route the request to a content server in a computer communications network by means of a coupled CN, to receive a response to the request, store the response in the local cache in the station, send the response to the end user device and transmit characteristic data of the response to the external load service.

Additional aspects of the invention will be summarized in part in the description that follows and in part will be obvious from the description or can be learned by. the practice of the invention. The aspects of the invention will be realized and obtained by means of elements and combinations indicated particularly in the appended claims. It will 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.
BRIEF DESCRIPTION OF THE FIGURES The present invention will now be described by way of example only with reference to preferred embodiments as illustrated in the following figures.
Figure 1 is a pictorial illustration of a process for caching content with remote loading services in a RAN, according to a preferred embodiment of the present invention; Figure 2 is a schematic illustration of a RAN-based data processing system configured to cache content with remote upload service, according to a preferred embodiment of the present invention and Figure 3 is a flow chart illustrating a process for caching content with remote loading services in a RAN, according to a preferred embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION Modes of the invention provide caching of content with remote loading services in a RAN. According to one embodiment of the invention, a containment request can be received in a caching storage processor running in memory for a computing device in a base station of a cell in RAN of a cellular communications network such as a 3G cellular communication system or UMTS. The content request can be inspected to determine if a response to the request can be found in a local cache memory to the base station. If so, the response stored in cache to the request can be returned to the requesting end user device. Otherwise, a response can be received by means of a CN coupled to the RAN and returned to the end user device. In addition, to the extent that it is determined that the response can be stored in cache memory, the response can be placed in the local cache memory of the base station and a remote load service external to the base station can be notified of caching of the response in order to handle billing externally to the base station.
In a further illustration, Figure 1 pictorially illustrates a process for caching content with remote loading services in a RAN. As shown in Figure 1, a cellular telecommunications network may be provided to include different base stations 120 arranged to provide wireless telephone access to different end user devices 110 for the PSTN 140. Groups of the base stations 120 may be communicatively linked. to a common RNC 130 which in turn can be coupled to a CN 150 thus forming a RAN. The CN 150 may include both an SGSN 180A which acts as a gate for traffic between the CN 150, the PSTN 140 and each RNC 130 as well as a GGSN 160B which acts as a gate between the CN 150 and the data communications network 100 -commonly global internet. The CN 150 itself can support a number of content services 160 as is well known in the art.
It will be noted that a data processing system for caching with remote load 190a can be exposed on one or more of the base stations 120 and can be configured for communicative coupling to a load service 190 running on RNC 130 externally to the base station 120. The data processing system 190A may include program codes that when executed in the data processing system process requests for content that are derived from the end user devices 110 that communicate with the station of base 120 to service cached responses locally to the end user devices 110. Program codes, when executed, may additionally retrieve 190C responses from content servers 180 in the data communications network 100 by means of the CN 150 that have not been cached and can return those recovered 190C responses to user devices final 110. Still further still, the program codes when executed may provide to the load service 190B data pertaining to the nature of the recovered responses 190C once cached locally in the base station 120 such that the load service 190B can process the billing resulting from the caching of the retrieved 190C responses.
In still a further illustration, Figure 2 is a schematic illustration of a RAN-based data processing system configured for content caching with remote charging services in a packet data network, such as a 2.5G network or 3G. The system may include a base station 200A coupled to an RNC 200B in a communications network 150, commonly an IP network or an asynchronous transfer mode network (ATM). The base station 200A may include a receiver / transmitter 230 that receives in-air communications from different end-user devices within the transmission range of the base station 200A via the antenna 265 and which routs the same to the RC 200B by means of of the network interface 210. A processor 240 may be provided to perform computational processing on the received data as the data is placed in the memory 220.
The RNC 200B, in turn, can include a host computer 260 with at least one processor and memory that supports the execution of an operating system 270. The operating system 270 in turn can host the execution of a load service 280. The load service 280 may write records to a customer charge data storage 290 in advance of customer service-oriented charges for data services provided to different customers of a RAN-based data processing system. In compliance with the load service 280, a cache storage with remote load module 300 can be arranged in the base station 200A together with a local cache memory 275 coupled to the cache storage with the remote load module 300.
Caching with remote loading modules 300 may include program codes that when executed by the processor 240 of the base station 200A may process requests for data received from end-user devices wirelessly coupled (not shown) when returning responses cached in the local cache memory 275 or for recover the responses of the data communication network 150 and to cache the responses retrieved in the local cache 275. In addition, when a response is placed in the local cache 275 the program code of the caching with the module Remote load 300 may provide characteristic data of the cached response and optionally the request to the load service 280, such as a size of the response stored in cache. In this regard, caching with the remote loading module 300 can provide the characteristic data to the load service 280 in real time or in batches together with other characteristic data for other responses stored in cache.
In still yet a further illustration, Figure 3 is a flow chart illustrating a process for caching content with remote load services in an RA. Beginning in block 310, a data request may be received at a RAN base station of an end user device that communicates wirelessly with the base station. In block 320, a local cache memory in the base station can be queried for a response to the request. In decision block 330, if a response to the request can be located in the local cache memory, in block 340, the response can be returned to the end user device. Otherwise, in block 350, a response to the request can be retrieved from a content provider on the internet by means of a CN and a corresponding RNC and finally back to the base station.
In decision block 360, it can be determined whether the response is cacheable or not (for example, whether a content filter would prevent caching of the response or not). If not, in block 340, the response can be returned to the end user device. Otherwise, in block 370 the response can be placed in the local cache memory of the base station and in block 380 the size of the response can be calculated (and optionally of the request that leads to the response). After this, in block 390, a remote load service in the RNC can be invoked by means of an interface to the remote load service with an identity of the requesting end user device and the response size and optionally an identification of the response and size of the request. Finally, in block 340, the response can be returned to the end user devices.
