Description

Wireless device network insight delivery method {NETWORK INSIGHT DELIVERY}

The present invention relates to mechanisms for conveying network insights to a device such as a wireless device.

Data analytics insights are transforming various industries by linking these insights and decisions. The network infrastructure generates network insights from, for example, evolved node B (eNB), radio applications cloud server (RACS), and customer experience manager (SAI/CEM). These types of insights can be useful in many devices or elements of a network. For example, this type of information may be useful for mobile applications, ie apps. As is known, an app may be considered a self-contained program or a piece of software designed to fulfill a special purpose, especially when downloaded to a mobile device by a user. Apps on mobile devices (eg, smartphones, tablets, etc.) use nuanced and rapidly changing app knowledge to make many decisions.

However, there is a need for a solution that provides easy access to insights that apps can use in their internal decisions.

In order to solve the above-described conventional problem, the present invention aims to provide a need for a solution that provides easy access to insights that apps can use in their internal decisions.

In order to solve the above-described technical problem, the method for transmitting network insights to a wireless device according to the present invention includes the steps of detecting at least one Wi-Fi advertised value by an application running on the wireless device, and Extracting, from the advertised value, at least one cellular network insight for cellular network conditions.

According to the present invention, it has the effect of providing a need for a solution that provides easy access to insights that apps can use in their internal decisions.

Does not.

There are a number of use cases where apps use insights to generate efficiencies and monetization for both apps and network operators. As an example, you decide to download some videos from the internet, but consider an idle app that is flexible with respect to timing. Today, apps don't know the local cell link speed (because the app is idle), and the app doesn't know the link speed in other cells. Thus, the app will not be able to find the fastest download opportunity, so the app will download less opportunistically, possibly discovering, for example, 06 Mbps, consuming a long time on the channel and draining battery life. . However, if using Network Nnowledge, the app will know when and where the least congested opportunities are using push notifications for the fastest download times or network knowledge that provided the fastest cell ID. In this way, the app uses much less battery life (e.g. not 100% due to less time on a channel that is 6 Mbps). Because downloading in this way also shifts traffic from congestion, it is beneficial to network operators. For example, there are more examples related to streaming, video telephony, gaming, user alerts, home screens, Wi-Fi or navigation. Network knowledge, very simply, fundamentally supports all Insights use cases.

As mentioned above, there is a need to enable networking insights to be easily accessed by such apps so that apps can make better decisions about when and how to take certain actions. 1 illustrates an example of using Insight. In this example, an app, such as a social networking app, may want to download videos or other information. Without access to network insights, the app may attempt to download information during periods of high congestion that incur longer download times and drain battery life.

However, through access to cellular or network insights, the app can determine when lower congestion periods exist and perform its desired actions during those lower congestion periods, thereby allowing faster download times. And save battery life. It should be noted that Figure 1 illustrates only one of the many opportunities that can be created by apps that utilize cellular congestion insights. Many other examples and uses are possible.

In another example, an application may need to access an authentication challenge value to access local management and configuration of the cellular access point. This authentication challenge value is an example of a networking insight that can help make better decisions about how such an app takes this action.

To connect the network insights with the app/application service provider, cellular congestion insights can be conveyed as the application activates the cellular modem and transmits and receives some information over the wireless link. 2 illustrates an example of delivery of insights to apps through a bearer path.

IEEE 80211 provides two methods of conveying additional information elements to wireless devices without persuading the wireless devices to authenticate the Wi-Fi network. The information elements are regularly transmitted, mainly containing a service set identifier (SSID), a homogeneous SSID (HESSID) in case of HS20 enabled Wi-Fi access, and a basic SSID (BSSID) to provide a unique identifier for such an access point. Information elements included in BEACONS, which are broadcasts, or an access network query protocol (ANQP) introduced by IEEE 80211u that allows provision of more comprehensive information as a response to a query by a wireless device prior to authentication. It can be provided by any one of comprehensive advertising services.

Since beacons have to be broadcast frequently with the most robust modulation and coding, the available space for additional information in beacons is very limited to avoid wasting a huge portion of the available spectrum.

To overcome the limitations of broadcasting generic information to beacons, IEEE 80211u provides a special protocol that runs in the pre-association stage, which can be used to actively query generic information from the access network. Such a service is currently limited to additional information about the Wi-Fi access point and can be extended by the recently established project IEEE 80211aq for various service discovery protocols. 3 illustrates an example of a generic advertisement service (GAS) messaging diagram.

Embodiments of the present invention are used to convey cellular access specific network insights to smartphones, tablets, or apps running on other mobile or wireless devices, e.g., the SSID field or hot spot 20 dictionary of Wi-Fi. -Provides the use of the Wi-Fi advertised value of the text within the associated advertisement message. Embodiments of the present invention also provide additional information on how to deploy the GAS/ANQP protocol discussed above to convey cellular access specific network insights according to service discovery protocols such as the 3GPP ANDSF protocol.

Thus, one embodiment broadcasts cellular access specific network insights, signals cellular access specific network insights without activating a cellular modem, and communicates cellular access specific network insights without consuming additional Wi-Fi/cellular resources. It is configured to utilize existing Wi-Fi messages to connect the application service provider.

4 illustrates a system according to an exemplary embodiment of the present invention. As illustrated in FIG. 4, the system can communicate with one or more (cellular) base stations 107 and/or one or more Wi-Fi access points (APs) 105 or one or more mobile devices served by them. They may include 100. Base stations 107 and/or Wi-Fi access points (APs) 105 are, in turn, PDN GW (packet data network gateway), which may be connected to, for example, the Internet or a wide area network (WAN). 115) and may be connected to or communicate with the core network.

In an embodiment, as illustrated in FIG. 4, the base stations 107 and/or Wi-Fi access points (APs) 105 communicate with or correspond to a performance information manager (PIM) or network monitor 113. Can be connected. In addition, a Wi-Fi access point can be literally integrated with a cellular access point to further enable this network monitoring communication embodiment. Likewise, the PDN GW 115 may also communicate with or be connected to the performance information manager 113. In certain embodiments, the performance information manager 113 may eventually be connected to the Wi-Fi AP controller 110 that controls the Wi-Fi access points (APs) 105. Optionally, the PDN GW 115 may also communicate with or be connected to the Insight Configuration Server 120, which may also be connected to or communicate with the Wi-Fi AP controller 110.

5 illustrates a signaling diagram illustrating an example of how to organize Wi-Fi systems to convey specific cellular network insights to devices running one or more applications (eg, wireless devices).

The method includes, in step 200, that a cellular network (e.g., eNB/RAN, performance management system/PIM) provides a cellular network congestion insight to a Wi-Fi network or a Wi-Fi-based cellular insight configuration server. Can include.

Subsequently, the method may include, in step 202, providing a Wi-Fi advertised value update.

The method may also include, at step 204, that the device (or an application running on it) detects at least one Wi-Fi advertised value. The method may also include, in step 205, extracting, from the at least one Wi-Fi advertised value, at least one network insight for the network condition.

In an embodiment, at least one Wi-Fi advertised value is communicated to the wireless device within a hot spot 20 pre-associative advertisement message. According to certain embodiments, the at least one Wi-Fi advertised value includes a Wi-Fi SSID (eg, HE SSID, HE SSID) name.

In some embodiments, the rules or mapping for encoding/decoding/extracting network insights from the received Wi-Fi advertised value exchanged in step 207 may be pre-provisioned to the wireless device, e.g., given It may be downloaded from at least one of an Internet server, for example, a network knowledge server, an ANDSF server, hotspot 20 signaling, or 3GPP signaling.

In other embodiments, the rules or mapping for encoding/decoding/extracting network insight from the received Wi-Fi advertised value may be, for example, current cell ID number, time of day, location, encryption key and seed. It may include a function of other parameters including at least one of. According to an exemplary embodiment, the actual insight itself may be hashed or encrypted using, for example, a predominant macro LTE cell ID number and/or a separate encryption key. This may make it possible to prevent apps that have not paid for access to the insights from being able to extract the insights. For example, apps that did not pay for full access or access to insights would not have an encryption key that would make the SSID opaque.

According to another embodiment, the rules or mapping for encoding/decoding/extracting network insight from the received Wi-Fi advertised value is the SSID value so that the SSID value can be signed and verified by detecting and decoding the SSID value. It may be such that the value includes redundancy. This may be analogous to using a long CRC-like field on the end of the SSID or forward error correction mechanisms to allow the app to verify that the dissected SSID is actually a valid SSID that actually conveys network insight.

According to another embodiment, the app may leverage the Wi-Fi Hotspot 20 pre-association process to verify that the received SSID is reliable and can be decoded to extract cellular condition insights.

Returning to FIG. 5, in an embodiment, the wireless device (or application running thereon) generates at least one application adaptation and/or runs on or tethered to the wireless device in step 210. The values of the extracted network insights can be used to provide insights to at least one other application. In an embodiment, the network condition encoded in the SSID or pre-association signaling may include at least one of the network conditions of one or a plurality of cellular communication links.

Depending on the embodiment, a network node, such as a Wi-Fi based cellular insights configuration server, may be configured to perform a method comprising detecting a first level of cellular network congestion on the first cellular wireless network. In response to this detection, the network node may communicate the SSID text value over the second wireless network (eg, a Wi-Fi network). The SSID text value may encode the detected first level of wireless network congestion. Also, the network node may additionally detect the second level of network congestion on the first wireless network. In response to this detection, the network node may convey the second SSID text value over the second wireless network. This second SSID text value may encode a second level of wireless network congestion.
