Service trial system and method for individuals and communities

[0001] The invention disclosed broadly relates to the field of service discovery, service trial either by an individual or a community and person to person marketing of services using wireless mobile communication technology.

[0002] The ubiquitous mobile wireless devices that communicate over cellular telephone networks, wireless LAN networks, and/or Bluetooth networks, enable large portions of the public to easily communicate with one another. The prevalence of mobile wireless devices offers promotional opportunities to businesses to attract customers among the wirelessly-communicating public. Consumer-oriented businesses sell a wide variety of services online to individual customers. The enterprising consumer-oriented business owner can promote their business by attracting members of the wirelessly-communicating public with free trial offers of online services. The business can make a promotional offer to potential customers of membership in an online club or organization sponsored by the business, which features free trials of online services for a limited period of time.

[0003] The problem is how to gather enough interested customers to become members of the online club to justify the time, effort, and expense that must be expended by the business to show a profit from the promotion. A corollary to this problem is how do new members of the wirelessly-communicating public discover the online services that are available. A further problem is how does the business monitor the duration of trial membership for individual customers so that the customer can be offered the service for a fee after the trial period expires.

[0004] In accordance with one embodiment of the invention, the enterprising business provides an interactive online service, that will be useful to interested members of the wirelessly-communicating public, by providing to them a medium to discuss and collaborate amongst themselves via their mobile wireless devices about topics of interest that are related to the services that the service provider sells online. Online communities of wireless users can interactively share their individual, real-time observations to build up a body of commonly accessible online information. Such online communities benefit from the addition of new members to increase the coverage and accuracy of the online body of information they gather. The invention enables an enterprising business to exploit this natural desire of such online communities to attract new members. Examples of business ventures that can benefit from the invention include an online provider of highway traffic reports, a ski equipment shop sponsoring online reports of skiing conditions, and a surfing equipment shop sponsoring online reports of local surfing conditions. The invention enables the service provider to promote its business by attracting new members from the wirelessly-communicating public with free trial subscriptions to the service for a limited period of time. In this manner, there is an affinity and loyalty developed in the new members toward the service provider, which will ultimately result in online purchases of services or goods from the service provider after the period of the free trial service expires. In accordance with an embodiment of the invention, the trial subscription is shared by the new member with friends, who will also enjoy the free trial service for a limited period of time, thereby enabling the service provider to attract a larger number of potential customers.

[0005] In accordance with another embodiment of the invention, mobile wireless devices have a Service Trial Client software module embedded in them at the time of their manufacture or later by downloading. The Service Trial Client includes an icon that is displayed on the mobile wireless device with a link to a Service Trial Server. When activated by the device's user, the link wirelessly connects the mobile wireless device to the Service Trial Server and downloads from the server a general catalog of available online services, such as a highway traffic monitoring service for motorists.

[0006] For each available online service listed in the catalog, at least one, and optionally two, icons associated with the service provider of the service are presented. A Service Trial icon is displayed on the mobile wireless device with a link to trial-provisioning logic within the Service Trial Server to set up the trial service subscription to be provided by the service provider for a limited period of time for the user's mobile wireless device. Optionally, a second icon is displayed on the mobile wireless device with a direct link to the service provider to set up a normal, paid-subscription service to be provided by the service provider to the user's mobile wireless device.

[0007] In accordance with a further embodiment of the invention, the Service Trial Server includes a database for each service provider employing the server for providing trial services to the wirelessly-communicating public. A service provider's database in the Service Trial Server includes a record for each trial service subscriber to the service provider's service. Each subscriber record includes the subscriber's wireless network address, the expiration date for the subscriber's trial period, and, optionally, the wireless network addresses of friends who will share the trial service.

[0008] During the provisioning phase, when the trial service subscriber applies for the trial subscription, the Service Trial Server sends the subscriber's wireless network address to the service provider, which replies with an authorization code that is optionally stored in the subscriber's record. The authorization code is forwarded by the Service Trial Server to the Service Trial Client software module in the user's mobile wireless device. If the trial service subscriber has added the wireless addresses of one or more friends, the authorization code is forwarded by the Service Trial Server to each of the named friends along with an invitation to join in the free trial service. If a friend accepts the invitation, a notice is sent to the trial service subscriber that the friend has joined in the trial. The friend can access the service on the same basis as can the trial service subscriber.

[0009] In accordance with another embodiment of the invention, there are two ways that the trial service subscriber's mobile wireless device can access the service during the subscriber's trial period. The first way is by the subscriber's mobile wireless device directly addressing the service provider over the wireless network and sending the subscriber's authorization code. The service provider will send a query including the subscriber's wireless address and authorization code to the Service Trial Server, which will check the subscriber's record to confirm that the subscriber's trial period has not expired. The Service Trial Server then responds to the service provider whether the subscriber is still within the trial period, and if so, the service provider then proceeds to provide the service to the subscriber. If the subscriber's trial period has expired, then the Service Trial Server sends a message directly to the trial service subscriber and the friends listed in the subscriber's record to subscribe to the service provider's normal paid-subscription service at the end of the trial period.

[0010] The second way that the trial service subscriber's mobile wireless device can access the service during the subscriber's trial period is send the request for the service to the Service Trial Server. If the subscriber's record shows that the subscriber's trial period has not expired, then the Service Trial Server sends a message to the service provider including the subscriber's wireless address and authorization code, authorizing the service provider to provide the service to the subscriber.

[0011] Monitoring logic is included in the Service Trial Server to review the record of each trial service subscriber on a periodic basis and to prompt the trial service subscriber and the friends listed in the record to subscribe to the service provider's normal paid-subscription service at the end of the trial period.

[0012] When the subscriber's record includes the wireless network addresses of the subscriber's friends who will share the trial service, logic in the Service Trial Server sends the friends' wireless network addresses to the service provider along with the subscriber's wireless address and authorization code. In accordance with another embodiment of the invention, there are two ways that the authorization code is forwarded to the Service Trial Client software module in the friends' mobile wireless devices. The first way that the authorization code is forwarded to the Service Trial Client software module in the friends' mobile wireless devices is by the Service Trial Server addressing the friends' mobile wireless devices and sending the authorization code and an invitation to a free subscription to the service.

[0013] The second way that the authorization code is forwarded to the Service Trial Client software module in the friends' mobile wireless devices is by the subscriber's mobile wireless device directly addressing the friends' mobile wireless devices and sending the authorization code and an invitation to a free subscription to the service. The friends who choose to participate in the trial subscription can make their request for service in the same manner as does the original trial subscriber.

[0014] In accordance with another embodiment of the invention, where a friend's mobile wireless device does not include the Service Trial Client software module, the subscriber can send a copy over the wireless network for downloading on the friend's device.

[0015] The resulting invention provides a complete over-the-air service trial and subscription tool that integrates discovery, trial, and subscription functions for online services. It enables a free trial period based on the service provider's specification, it enables person-to-person advertising of the service and communal trial and subscription to the service, and it enables prompting existing subscribers about new services.

[0044] An online, highway traffic monitoring service is an example of a service that is based on having a critical mass of members in an online community. The example provider of the service prepares online reports on automotive traffic congestion and hazards in a geographic region. Revenue for the service provider is derived from motorists subscribing to the reporting service, which allows them to access its traffic reports via their mobile wireless devices. Real-time information about automotive traffic congestion and hazards is provided by the subscriber motorists, themselves, who call or send messages the service provider and describe their on-the-scene observations, which are then compiled by the service provider into the traffic reports accessible to all subscribers. The accuracy and timeliness of the traffic reports depend on having a large number of subscribers. The service provider promotes its business by attracting new members of the wirelessly-communicating public with free trial offers of the service for a limited period of time. Motorists who participate in the free trial of the service and existing subscribers, as well, are interested in enlarging the membership in order to maximize the accuracy and timeliness of the traffic reports.

[0116] The steps of the flow diagram of FIG. 8 are as follows:

[0117] Step 810: displaying a Provider's Service Trial Icon of an online service provided by a service provider, the Provider's Service Trial Icon displayed on a user's mobile wireless device with a link to trial-provisioning logic within a Service Trial Server to set up a trial service subscription to be provided by the service provider for a limited period of time to the user's mobile wireless device.

[0118] Step 812: activating the Provider's Service Trial Icon and its associated link to cause the Service Trial Server to set up the trial service subscription with a Service Trial Client in the user's mobile wireless device.

[0119] Step 814: sending wireless addresses of one or more friends' wireless devices in association with said activating step.

[0120] Step 816: sending the user's wireless network address from the Service Trial Server to the service provider.

[0121] Step 818: receiving an authorization code from the service provider that is forwarded by the Service Trial Server to the Service Trial Client software module in the user's mobile wireless device.

[0122] Step 820: distributing said authorization code and an invitation to join in the trial to said wireless addresses of the one or more friends.

[0123] Step 822: accessing the service by the user's and the friends' mobile wireless devices during the subscriber's trial period.

[0124] The resulting invention creates following benefits:

[0125] 1. Combines discovery, trial and subscription through a reliable and easily accessible channel.

[0126] 2. Service trial is extended from individuals to the community around them, which brings forward a strong case for person-to-person marketing.

[0127] 3. Fast and easy user experience Over-The-Air, at many locations.

[0128] 4. Enhanced download manager functionality.

[0129] 5. Social aspects on service trials: end users can see services immediately in their social context without having to wait until there are enough friends who have the service activated.

[0130] 6. End users can try before subscription: The threshold for service trial is much lower and end users can find benefits of new services before committing to them.
