`

`INTELLIGENT CACHE MANAGEMENT IN CONGESTED WIRELESS
`
`NETWORKS
`
`In the art today there are performance enhancing proxies and general standards for
`
`improvements of TCP performance in wired and wireless networks. Some of these techniques
`
`use clients and some are clientless. Some can look at network performance to enhance the
`
`optimization they provide. As noted, some may utilize a client and some may operate clientless.
`
`Almost all, if not all, are focused on optimization based on only a one-sided view of the
`
`networks connected to such a platform- either outbound wired, inbound/outbound wireless, or
`
`based solely on the cooperation with a client.
`
`As recognized by the inventor(s), when applications running in the background manage
`
`similar or the same content as an application running in the foreground (or in the case of
`
`programmatic updates in a user controlled foreground application-like the Yahoo! Sports
`
`scores examples- combined with the user hitting refresh), the resulting demand on a data
`
`network can produce congestion problems. As an example, a popular application such as eBay
`
`monitors for transaction changes (such as bid changes) using an programmatic process in the
`
`background and a user controlled view in the foreground which provides the user the ability to
`
`experience 'real-time' refreshes for bid changes.
`
`However, congested networks, heavily loaded content sites and anxious users can
`
`produce a slow or no-response, prompting the user to press refresh more often (e.g., the user is
`
`regularly hitting the refresh button, fetching foreground updates) adding to the congestion
`
`problems, network bandwidth consumption and further decreasing mobile device battery life.
`
`Description of One or More Embodiments of the Invention
`
`Embodiments of the present invention provide a system that optimizes multiple aspects of
`
`the connection with wired and wireless networks and devices through a complete view of activity
`
`including: loading, current application needs on a client, controlling the type of access (push vs.
`
`2
`
`Page 5 of 57
`
`

`

`pull or hybrid), location, concentration of users in a single area, time of day, how often the user
`
`interacts with the application, content or device, and using this information to shape traffic to a
`
`cooperative client/server or simultaneously mobile devices without a cooperative client. Because
`
`the inventive server is not tied to any specific network provider it has visibility into the network
`
`performance across all service providers. This enables optimizations to be applied to devices
`
`regardless of the operator or service provider, thereby enhancing the user experience and
`
`managing network utilization while roaming. Bandwidth has been considered the major issue in
`
`wireless networks today. More and more research has been done related to the need for
`
`additional bandwidth to solve access problems- many of the performance enhancing solutions
`
`and next generation standards, such as L TE and WiMAX are focused on providing increased
`
`bandwidth. However, history has shown that this simply doesn't solve all the problems. A key
`
`problem is lack of bandwidth on the signaling channel more so than the data channel.
`
`Embodiments of the present invention align requests from multiple applications to
`
`minimize the need for several polling requests; leverage specific content types to determine how
`
`to proxy/manage a connection/content; and apply specific heuristics associated with device, user
`
`behavioral patterns (how often they interact with the device/application) and network parameters.
`
`Embodiments of the present invention move recurring http polls done by various widgets,
`
`RSS readers etc. to a fixed internet (NOC), thus considerably lowering device battery/power
`
`consumption, radio channel signaling, and bandwidth usage. Additionally, embodiments ofthe
`
`present invention do this transparently so that existing applications do not need to be changed. In
`
`some embodiments, this can be done by implementing a local proxy on the device which
`
`automatically detects recurring requests for the same content (RSS feed, Widget data set) that
`
`matches a specific rule (e.g. happens every 15 minutes) and automatically caches the content on
`
`the client while delegating the polling to the server (e.g., to a proxy or virtual proxy operated as
`
`an element of a communications network). The server would then notify the mobile/client proxy
`
`if the content changes, and if content has not changed (or not changed sufficiently, or in an
`
`identified manner or amount) the mobile proxy provides the latest version in its cache to the user
`
`(without need to utilize the radio at all). This way the mobile device (e.g., a handset) does not
`
`3
`
`Page 6 of 57
`
`

`

`need to open up or use a data connection if the request is for content that is monitored and that
`
`has been not flagged as new/changed.
`
`The logic for automatically adding URLs/content to be monitored can check for various
`
`factors like how often the content is the same, how often the same request is made (is there a
`
`fixed interval/pattern?), which application is requesting the data, etc. Similar rules to skip using
`
`the cache and request the data from the original source may also be used. For example, when the
`
`request comes at an unscheduled/unexpected time (user initiated check), or after every (n)
`
`consecutive times the response has been provided from the cache, etc., or if the application is
`
`running in the background vs. in a more interactive mode of the foreground. As more and more
`
`mobile applications base their features on resources available in the network, this becomes
`
`increasingly important. Embodiments of the present invention also remove unnecessary chatter
`
`from the network, benefitting the operators trying to optimize the wireless spectrum usage.
`
`In some embodiments, the present invention includes a distributed proxy for network
`
`traffic optimization, as shown in Figure 1. The main components include a proxy client running
`
`on a device [1 05], a proxy server running in the network [1 02], and an internal protocol between
`
`the proxy client and the proxy server [109, 110]. Typically, the proxy client and proxy server
`
`would be implemented as a set of instructions executed by a (micro) processor, although other
`
`implementations are possible (firmware, etc.). The proxy client, shown in Figure 2, includes
`
`connection management functionality [206], application protocol logic modules [213], a local
`
`cache [203], and an interface to retrieve information on device properties (e.g., information on
`
`device battery level, whether the device is being actively used or not, and the registered network)
`
`[210]. The proxy server, shown in Figure 3, includes connection management functionality
`
`[302], application protocol logic modules [31 0], a connection and content metadata database
`
`[303], and a device information database [304].
`
`In general operation, the proxy client [202] is an application independent proxy that
`
`mobile applications [200] can use to open any TCP connection to any host. The proxy client will
`
`detect the type of traffic and utilize an appropriate application protocol module [213] to process
`
`the traffic. With the chosen protocol/logic module, the proxy client may process the data locally
`
`4
`
`Page 7 of 57
`
`

`

`and generate necessary talkback communication using its local cache, communicate the
`
`processed data along with device properties to the proxy server using the internal protocol [11 0],
`
`modify or delay any data before sending it to the proxy server, detect usage patterns between
`
`similar connections and provide this to the proxy server as connection metadata, or any
`
`combination ofthe above.
`
`If the proxy server is contacted regarding processing the original connection, the proxy
`
`server will utilize an appropriate application protocol module [31 0] to process the traffic. With
`
`the chosen protocol/logic module, the proxy server may contact the intended target of the
`
`connection and route the data from the proxy client to the target, generate talkback
`
`communication using its local cache, modify or delay any talkback communication data based on
`
`the device properties, and based on the connection metadata, start background processing to
`
`gather data for later use with similar connections, as well as any combination of the above.
`
`Both the proxy client and the proxy server will, where applicable continue to observe and
`
`process the data using the application protocol modules for the entire duration of the connection.
`
`After the original connection no longer exists, the proxy client and proxy server may still share
`
`information about the ceased connection and its properties for later use with similar connections.
`
`In this mode of operation, the proxy server may signal the proxy client that some data in its local
`
`cache is no longer up to date (and hence is stale), or alternatively pre-load the client cache with
`
`the fresh data. This can be done in bulk to avoid multiple radio requests, or on an application by
`
`application basis.
`
`From a mobile application's [200] point of view, the proxy is transparent and no
`
`modifications are needed in the way the application uses the connections. Proxy-aware mobile
`
`applications [212] may also be implemented, and can provide additional information about the
`
`connection characteristics to the proxy client.
`
`In some embodiments, the present invention offers benefits with respect to network
`
`usage, in that by serving requests from the local cache, the proxy client reduces the number of
`
`requests that are done over the wireless network. Further, the proxy client and the proxy server
`
`5
`
`Page 8 of 57
`
`

`

`may filter irrelevant data from the communicated data. The proxy client and the proxy server
`
`may also accumulate low priority data and send it in batches to avoid the protocol overhead of
`
`sending individual data fragments. The proxy client and the proxy server may compress or
`
`transcode the traffic, reducing the amount of data sent over a wireless network. The signaling
`
`traffic in a wireless network is reduced, as the wireless network is used less often by optimizing
`
`small bursts away and the network traffic can be synchronized among individual applications.
`
`With respect to the battery life of a mobile device, by serving requests from the local
`
`cache, the proxy client reduces the number of times the radio module is powered up. The proxy
`
`client and the proxy server may accumulate low priority data and send it in batches to reduce the
`
`number of times and/or amount of time when the radio is powered up. The proxy client may
`
`synchronize the network usage by performing the hatched data transfer for all connections
`
`simultaneously.
`
`In some embodiments, the present invention may be used in the case of home screen
`
`widget polling for data using HTTP, as shown in Figure 4. In the normal flow of operation, the
`
`widget performs a HTTP request to the data provider server [405, 406]. If the data has been
`
`updated, the widget refreshes itself. The widget waits for a small period of time and starts over at
`
`the initial step. With respect to using a distributed proxy, the widget performs a HTTP request
`
`via the proxy client [407, 408]. The proxy client detects the connection type to be a HTTP GET
`
`request. The proxy client checks the local cache for any previous information about the request.
`
`If the locally stored response is not available, the client updates all information about the
`
`request and the time it was made for later use. The client sends the request to the proxy server
`
`and the server performs the request and returns the results. The client stores information about
`
`the result and returns the result to the requestor. If the same request has occurred multiple times
`
`(within a certain time period) and it has often yielded same results, the client notifies the proxy
`
`server that the request should be monitored for result changes [409]. If the request was marked
`
`for monitoring, the client will store the results into its local cache. If the locally stored response
`
`is available, the client will return the response from the local cache without performing
`
`communication over the wireless network [ 413].
`
`6
`
`Page 9 of 57
`
`

`

`Independently of the widget or client operation, the server proxy will perform the
`
`requests marked for monitoring to see whether the response has changed [410]. Whenever an
`
`unexpected response is received for some request, the server will notify the client that the
`
`response has changed and that the locally stored response on the client should be erased or
`
`replaced with a new response [416]. A subsequent data request by the client results in the data
`
`being returned from the proxy server [ 417, 418]. A benefit of using the distributed proxy in this
`
`case is that the wireless network is only used whenever the content for the widget has actually
`
`changed; the traffic required to check for the changes is not done over the wireless network. This
`
`reduces the amount of generated network traffic and shortens the total time and the number of
`
`times the radio module is powered up on the mobile device, thus reducing battery consumption.
`
`With respect to polling for changes in a mailbox, in the normal flow of operation, the
`
`mail client opens a connection to the mail server, the mail client authenticates with the server and
`
`queries for new email, and if new mail has arrived, a notification is shown. The mail client then
`
`closes the connection. The mail client waits for a period of time and starts over. A variation is to
`
`leave the connection open and start over at the second step after a predetermined period of time.
`
`In the context of a distributed proxy, the mail client opens a connection to the mail server
`
`via the proxy client, the proxy client detects the traffic type and the chosen application logic
`
`module simulates a mail server authentication, and the proxy client looks up from the local
`
`database whether information about the particular mail connection is available. If the information
`
`is not available, the connection is routed to the proxy server, the proxy server establishes a
`
`connection to the mail server and performs authentication using the data from the mail client, the
`
`data between the mail client and the mail server is directly routed through the proxy connection,
`
`and when the mail client closes the connection, the proxy client may choose to leave the actual
`
`connection to the backend open and store information about the connection into the local
`
`database for later use if the same mail connection has been used frequently. If the information is
`
`available, the client proxy will continue to simulate mail server responses for the mail client for
`
`all queries for which it has the data available. If the mail client performs an operation that cannot
`
`be simulated by the proxy client, the proxy client will route the data to the proxy server and the
`
`7
`
`Page 10 of 57
`
`

`

`proxy server will pass the data to the mail server and route the data between the two. The proxy
`
`server may need to re-establish the connection to the mail server at this point. When the mail
`
`client closes the connection, the proxy client may choose to continue to store information about
`
`the connection for later use or it may request the proxy server to terminate the mail server
`
`connection and remove any information about the connection from the database.
`
`Independently of the mail client or the proxy client, the proxy server will query the mail
`
`server for any changes that the mail client has previously queried. If any information in the mail
`
`server has changed, the proxy server will notify the proxy client to stop simulating any responses
`
`based on locally cached data in order to let the mail client receive the changed data from the mail
`
`server.
`
`Embodiments of the present invention mitigate application protocol keep-alive traffic.
`
`Existing application protocols may provide long lived connections that allow servers to push
`
`updated data to the client without the need of the client to periodically re-establish the
`
`connection or to periodically query for changes. However, the client needs to be sure that the
`
`connection remains usable by periodically sending some data, often called a keep-alive message,
`
`to the server and making sure the server is receiving this data. While the amount of data sent for
`
`a single keep alive message is not significant and the keep-alive interval for an individual
`
`application is not too short, the cumulative effect of multiple applications performing this
`
`operation individually will amount to small pieces of data being sent very frequently. Frequently
`
`sending bursts of data in a wireless network results in high battery consumption by a mobile
`
`device due to the constant need of powering the radio module. Each burst will also require a
`
`significant amount of signaling traffic in a wireless network compared to the actual data being
`
`sent. By using the inventive distributed proxy model, the proxy client can prevent the keep-alive
`
`messages (or at least many ofthem) from being sent over the network and the proxy server can
`
`independently generate the required keep-alive messages to maintain the actual backend
`
`connection.
`
`In alternative embodiments, the proxy client can be implemented directly into the TCPIIP
`
`stack of the device operating system. The proxy client can be bundled into a wireless modem to
`
`8
`
`Page 11 of 57
`
`

`

`provide transparent use for the device operating system. The proxy client can also be bundled
`
`into a firewall or a router to provide transparent use for the device operating system.
`
`Alternative embodiments apply similar techniques for a variety of protocols including
`
`HTTP, HTTPS, IMAP, POP, SMTP and ActiveSync. Use of application specific protocol
`
`handlers allows for optimization of any protocol that can be port mapped to a hander in the
`
`distributed proxy.
`
`INTELLIGENT CACHE MANAGEMENT IN CONGESTED WIRELESS NETWORKS
`
`As recognized by the inventor(s), by detecting the rate and shape of requests to the same
`
`URI (or another source of data), combined with the current state of the mobile device (e.g.,
`
`whether the backlight is on or off), the described virtual proxy can determine the difference
`
`between content that is programmatically refreshed and content that is requested by the user in
`
`the foreground. Using this information, along with the current network conditions such as the
`
`TCP connection delay and/or RTT, current radio coverage statistics, the virtual proxy can decide
`
`if and when to cache content locally. If content is already cached, then the cached version is
`
`presented to the user. If not, the request is passed through and the resultant content is presented.
`
`To ensure the user experience is not negatively impacted, the system can consider the
`
`"criticality of an application" as a factor. For example, financial applications may be considered
`
`critical so that they are always fetched and current data are always presented. An application, by
`
`name or type, can be considered critical at the time of provisioning. That is, the sever-side
`
`component of the virtual proxy can be provisioned with "profiles" which specify the criticality of
`
`the application. This profile is communicated to the device side of the virtual proxy during
`
`initialization or subsequent establishment of polling requests.
`
`A set of basic criteria (along with profile information) are applied to each URI to
`
`determine the suitability of related content for caching (size, etc.). The profile is also used to
`
`identify applications for which caching will typically not be appropriate, such as the Google
`
`Market. Additionally, the periodicity of each request as identified by a specific URI is
`
`9
`
`Page 12 of 57
`
`

`

`monitored by the proxy such that polling behavior can be detected, and the content cached as
`
`appropriate.
`
`When a URI has been identified as suitable for caching, a message is transmitted to the
`
`server component requesting that that the content associated with the URI be monitored for ·
`
`changes. When the server detects that the content has been altered, the server transmits a
`
`message to the device side proxy instructing it to invalidate whatever cache elements are
`
`associated with that URI.
`
`Typically, disk usage parameters as described by the carrier configuration are respected.
`
`As such, the client-side Proxy will usually not use more than the specified percentage of
`
`available disk space for cache entries. In addition to total disk usage, the client-side proxy also
`
`imposes a configurable limit on the total number of cache entries.
`
`Cache entries are aged out automatically by the client-side proxy as determined by
`
`configurable parameters. Additionally, cache elements may be removed to remain in compliance
`
`with disk usage or entry count restrictions.
`
`The client-side proxy will invalidate the entire cache should the server-side component
`
`become unavailable. The client-side proxy may encrypt cached textual content. Binary content
`
`(images etc.) is typically not encrypted.

`INTELLIGENT CACHE MANAGEMENT IN CONGESTED WIRELESS NETWORKS
`
`What is claimed is:
`
`1.
`
`A method of determining whether to cache data in a client device, comprising:
`
`determining that the client device has made a request for data from a data source
`
`over a communications network;
`
`determining whether the client device is in an active state or an idle state;
`
`accessing a profile for the application requesting the data from the data source;
`
`determining one or more current operational characteristics of the network; and
`
`based on the client device state, application profile, and current operational
`
`characteristics of the network, determining whether to cache a set of data in the client device.
