The present disclosure relates to information processing and, more specifically, to a method and apparatus for sharing wireless traffic.
In recent years, introduction of wireless Internet technology has led to a new era in mobile device development. Evolvement of this technology marks the end of an era when people can only access to a network through fixed devices. It now becomes practical to access to the network anywhere and anytime. Therefore, a considerable number of mobile network applications have quickly occupied the market and has become a trend. People use mobile devices to do things that could only be done previously with fixed networking devices, for example, QQ chatting, viewing Wiki, shopping, financial management, etc. Undoubtedly, the mobile Internet technology has, to a certain extent, changed the traditional lifestyle.
However, this new lifestyle also brings some troubles; for example, a great number of wireless Internet applications generate enormous traffic to the wireless network, such that mobile operators have to restrict wireless traffic. The current solution is that the operators either charge subscribers according to their traffic or provide so called packages to subscribers; i.e., providing a fixed monthly traffic to each subscriber under a fixed charge, and the extra traffic is charged relatively high. Most subscribers would select the packages in order to save money. However, the package traffic of some subscribers might not be sufficient temporarily due to particular circumstances, but the extra traffic will be charged relatively high and change of the package will not be effective till next month; therefore, it cannot satisfy the temporary need for the higher traffic. Moreover, since the need is temporary, frequent change of packages is not convenient for subscribers; while some other subscribers have abundant traffic, which would be a waste at the end of a month. For the subscribers as a whole, it is a very uneconomical operating mode.
Existing mobile operators generally issue a warning when a subscriber's traffic approaches to the upper limit of the traffic as specified in the package, but it cannot solve the problem that the subscriber's traffic is temporarily insufficient, and the subscriber has to pay extra money for the access to the network, while those subscribers that have much remaining traffic cannot share their traffic to the abovementioned subscribers. The mobile operators themselves have no intention to solve this problem, because sharing traffic among subscribers would increase the burden on mobile operators' networks, but cannot bring revenues to the mobile operators.
Therefore, it is desirable for a solution, which can share network traffic among mobile devices without participation of mobile operators, thereby saving money for subscribers.

The embodiments of the present disclosure are described in detail with reference to the accompanying drawings and specific examples.
In the embodiments of the present disclosure, a mobile device includes, but not limited to, various devices that can access the world wide web through the mobile Internet, such as a mobile phone, a laptop, etc.
In one embodiment of the present disclosure, a method for sharing wireless traffic as implemented on a sharing server is provided. The method is to be implemented on a traffic sharing server.
Specifically, at step 302, the request for sharing the wireless traffic is received from the requesting mobile device, the request containing a list of unique numbers of other mobile devices within a certain range of distance from the requesting mobile device. At present, many technologies can enable a mobile device to sense the surrounding mobile devices, for example, through the WiFi function on the mobile device and taking the requesting mobile device as a slave device, those surrounding mobile devices that have opened the WiFi primary device function can be sensed. The surrounding mobile devices that have opened the Bluetooth function may also be sensed through the Bluetooth technology; or the surrounding mobile devices may also be sensed through the positioning service provided by the wireless operator, and the like. Such requesting mobile device may obtain the unique numbers of other mobile devices within a certain range of distance from the requesting mobile device. For example, when using the WiFi technology, the unique number of the mobile device is a service set identifier (SSID); when using the Bluetooth technology, the unique number is a device number; and when using the positioning service provided by the wireless operator to sense the surrounding mobile devices, the unique number of a mobile device is a SIM card number (for example, a mobile phone number) of the mobile device. The requesting mobile device arranges the unique numbers of all other mobile devices within a certain range of distance from the requesting mobile device into a list that is embedded into the request for sharing wireless traffic, which is sent to the traffic sharing server.
In one embodiment, the request for sharing the wireless traffic from the requesting mobile device further comprises at least one of the following information of the requesting mobile device: a unique number, a size of traffic requested for sharing, a manner for selecting a mobile device for sharing traffic, a manner for sharing traffic, a period of time for sharing traffic, a location of the mobile device when sharing traffic, etc. As to the manner for selecting the mobile device for sharing traffic, if there are a plurality of mobile devices that can be selected by the traffic sharing server, they can be selected one by one according to the order as arranged in the list; they can also be selected according to the remaining traffic of the mobile devices in the list; or they can be selected according to connection signal strength of the mobile devices in the list. Further, the mobile devices can be weighted and then ranked based on the above various information, for example, the remaining traffic of the mobile device, the connection signal strength, being or being not a friend, and the like, so as to determine whether to be selected as the mobile device for traffic sharing. As to the manner for traffic sharing, it means in a traffic sharing request, whether only a single mobile device is selected for traffic sharing or a plurality of mobile devices may be used for traffic sharing, etc. Because some mobile devices have some requirements on the mobile device that is willing to share traffic, in order to meet these requirements, the requesting mobile device has to provide some information. Of course, the above information may also be extended as required. The above information may be directly embedded in a traffic sharing request at once or provided as required by the traffic sharing server.
The request for sharing traffic may be directly sent to the traffic sharing server by the requesting mobile device using an application layer protocol through the wireless Internet, for example, performing data transmission by using http, https protocols; or the traffic sharing server can provide a page, and the user of the requesting mobile device provides relevant information to the traffic sharing server by filling a form, or submits the request for sharing traffic using various other information interacting manners.
In one embodiment, the method further comprises step S301 to receive registration from at least one mobile device, wherein the at least one mobile device is registered as a mobile device for sharing wireless traffic. The objective of the mobile device to register with the traffic sharing server is to promise that the mobile device itself is willing to provide a traffic sharing service, such that other mobile devices can obtain an access password of the mobile device, use this mobile device as the access point of the mobile network, and thereby access the Internet. Preferably, the registration information contains the unique number of the mobile device and a connection channel password. The registration information may further contain some other information, for example, to which devices the traffic sharing service will be provided, specific time for providing the service, and the like. In one embodiment of the registration information, the registered mobile device may demand a mobile device group for sharing traffic; i.e., only providing the traffic sharing service to mobile devices in the mobile device group for sharing traffic. For example, the mobile device group for sharing traffic may be a list of friends of the mobile device's owner, or a set of other reciprocal mobile devices voluntarily offering to share their traffic, or a list of unique numbers of some mobile devices, and the like. The registration information may further comprise the size of traffic available for sharing, the period of time for sharing traffic, the location of the device when traffic is available for sharing, and the like. One or a part of such information may exist in the registration information. In one embodiment, the traffic sharing server stores the unique number of the registered mobile device to a list of unique numbers of the mobile devices available for sharing wireless traffic, and the list of unique numbers may include a plurality of unique numbers of the mobile devices, for example, SSID number, Bluetooth device number, and the like.
Preferably, the requesting mobile device is a registered mobile device. Moreover, in order to enhance the security for use, the registration information may further comprise a password set for the mobile device, and the request from the mobile device for sharing wireless traffic contains the password set for the mobile device. In this way, password verification may be performed upon submitting the request, thereby enhancing the system security.
At step 304, at least one mobile device for sharing wireless traffic is selected for the requesting mobile device from the received list. In one embodiment, the traffic sharing server selects, for the requesting mobile device, at least one device for sharing wireless traffic by matching the received list with the list of stored unique numbers of mobile devices for sharing wireless traffic. For example, when using the WiFi technology, the received list comprises a plurality of nearby mobile devices that can act as the WiFi access points; the traffic sharing server stores a plurality of registered mobile devices available for sharing traffic; therefore, by matching the unique numbers in the two lists, the selected mobile device for sharing traffic can be found. Of course, it is also possible that no available mobile device is found after the matching, a request failure will be returned to the mobile device. Preferably, the reason for failure may also be provided.
In one embodiment, if the registered user has certain requirements on mobile devices that are willing to provide traffic sharing in the registration information, when matching the received list with the list of the stored unique numbers of the mobile devices available for sharing traffic, the information contained in the request for sharing wireless traffic from the mobile device will be matched with the stored registration information of the mobile devices in the list of unique numbers of the mobile devices available for sharing wireless traffic. For example, the period of time for sharing traffic as required in the registration information is 8:00-10:00 am, while the requested time for sharing traffic is 2:00 pm; even if other conditions are satisfied, the mobile device cannot act as the selected mobile device. For another example, if the requesting mobile device does not select the manner for selecting a mobile device for sharing traffic, but the traffic sharing server finds that there may be a plurality of selected mobile devices, then it may send the available list to the requesting mobile device that selects one or more mobile devices therefrom as the mobile device(s) for sharing traffic. In one embodiment, all registration information of the mobile devices in the list of stored unique numbers of mobile devices available for sharing wireless traffic is matched with all information of the requesting mobile device for selection.
At step S306, the unique number of the at least one selected mobile device and its connection channel password are sent to the mobile device. In this way, the requesting mobile device is connected to the at least one selected mobile device in response to receipt of the unique identification number of the at least one selected mobile device and its connection channel password. In one embodiment, the traffic sharing server further sends, to the mobile device, the traffic available for sharing of each mobile device in the current request for the at least one selected mobile device. The traffic available for sharing in the current request is jointly determined by the current remaining traffic of the mobile device and the traffic available for sharing.
Preferably, the requesting mobile device may record the used traffic for sharing and send it to the traffic sharing server, or the selected mobile device may record the used traffic for sharing and send it to the traffic sharing server.
In one embodiment, the requesting mobile device disconnects from the selected one mobile device. At this point, the traffic sharing server will receive the usage amount of the shared traffic of the at least one selected mobile device in this request, such that the traffic sharing server may know how much traffic for sharing is provided by the registered device, and how much available sharing traffic still remains. In one embodiment, after sharing and using the traffic, the registered mobile device should also report its own remaining traffic to the sharing traffic server so as to avoid the circumstance in which it is still appointed as a mobile device for traffic sharing although its own remaining traffic is insufficient to provide traffic sharing. Thus, the traffic sharing server should further consider the stored usage amount of the shared traffic of the mobile device available for sharing wireless traffic when matching the request for sharing wireless traffic from the mobile device with the registration information of the mobile devices in the list of unique numbers of the mobile devices available for sharing wireless traffic.
In one embodiment, since the traffic sharing request is generally once-for-all, the connection channel password information of the selected mobile device may be channel password information temporarily generated by the traffic sharing server, which is different from the commonly used connection channel password information of the selected mobile device. The traffic sharing server may maintain the mapping relationship between the passwords and notify the generated connection channel password to the selected mobile device for traffic sharing. When receiving a request for accessing the Internet by using the connection channel password information, the selected mobile device for traffic sharing would map the connection channel password information to its real connection channel password based on the above password mapping relationship, thereby allowing for connection. In another embodiment, the traffic sharing server may generate a connection password for the registered mobile device regularly, and update it regularly, such that access is allowed when the selected mobile device receives the connection request, which may also achieve the objective of security.
The traffic sharing server may maintain traffic requesting conditions among respective mobile devices, traffic sharing situations, registration information of mobile devices, a list of mobile devices available for sharing traffic, and other information. The above information may be stored in a database or in other manners.
The requesting mobile device and the selected mobile device may be present in the mobile operation network of a same mobile operator or not in the mobile operation network of the same mobile operator, as long as the mobile devices may sense the location of the other party and may act as the network access points. The specific technical solution for sharing is similar to the traffic sharing between the mobile devices of the same mobile operator.
Based on the same inventive concept, the embodiments of the present disclosure further disclose a method of a requesting mobile device for requesting sharing wireless traffic. The method is to be implemented on the requesting mobile device.
In one embodiment, the requesting mobile device should further get other mobile devices within a certain range of distance from the requesting mobile device. For example, the selected mobile device acts as the WiFi primary device, then the requesting mobile device may request for connecting with a mobile device whose SSID number is the received unique number. Through the connection channel password, the selected mobile device acts as the WiFi access point to access the Internet. For another example, the selected mobile device acts as a Bluetooth device, then the requesting mobile device may request for connecting with a Bluetooth mobile device whose device number is the received unique number. Through the connection channel password, the Internet is accessed.
In one embodiment, when the requesting mobile device is using the shared traffic, if the mobile device for sharing its traffic is leaving, the connection strength between the requesting mobile device and the mobile device providing the service will become increasingly weaker, and when the weakness reaches a certain extent, the requesting mobile device can not access the Internet, and the connection will be disconnected. In other words, the requesting mobile device disconnects from the at least one selected mobile device in response to the connection strength with the at least one selected mobile device being lower than a set threshold. The set threshold may be set by the requesting mobile device, for example, 75% of the connection strength. The specific value is dependent on the specific connection strength under which the data transmission for the requesting mobile device is stable.
In another embodiment, receiving the unique number of the at least one selected mobile device and its connection channel password further comprises: receiving the traffic available for sharing of each selected mobile device in the current request for the at least one selected mobile device, and the method further comprises: the mobile device disconnecting from the selected one mobile device in response to the used traffic for sharing reaches the traffic available for sharing of a mobile device in the current request for the at least one selected mobile device.
In one embodiment, in response to the number of the at least one selected mobile device being more than one, after the mobile device disconnects one of the selected mobile devices, it connects with the next selected mobile device. In this way, it may continuously use a plurality of selected traffic-sharing mobile devices; moreover, for a requesting mobile device, such handover may be transparent, and the user of the requesting mobile device can barely sense it. If all of the selected mobile devices in one request have been disconnected, while the requesting mobile device still has a request for sharing traffic, it may initiate another request for sharing traffic to the traffic sharing server.
Based on the same inventive concept, embodiments of the present disclosure further provide a system for sharing wireless traffic.
