Description
Technical Field
The present invention relates to a service providing technology, and in particular, to a heterogeneous network based service providing method and system, and a media server.
Background
The heterogeneous network technology attracts more and more attention as an emerging technology, and is regarded as a key technology of B3G/4G. This presents new challenges to current wireless communication technologies as future wireless or cellular communication systems require increased coverage to support higher rate data transmissions. At the same time, the cost of communication system construction and maintenance is more significant. With the continuous increase of the transmission rate and the communication distance, the energy consumption problem of the mobile terminal battery becomes prominent, and the future wireless communication adopts higher frequency, so that the path loss attenuation caused by the higher frequency is more serious, and the energy consumption problem of the mobile terminal battery is more prominent. By the heterogeneous network technology, a large number of base stations such as a micro-power base station Pico, a home base station femto, a Relay base station Relay and the like are adopted, cell splitting can be effectively carried out, most of data services are distributed to nodes mainly covering hot spots and indoor coverage, and due to the fact that the transmission distance is shortened, path loss is greatly reduced, data transmission quality is improved, the communication range is expanded, the overall throughput is improved, and therefore faster and better services are provided for users.
Taking a Relay base station Relay as an example, fig. 1 is a schematic diagram of a Relay network architecture, illustrating a structure of a typical Relay Node, as shown in fig. 1, in a Relay network, a Link between a Relay cell user (R-UE) and a Relay station where a Relay station (RN, Relay Node) participates in service is called an Access Link (Access Link), a corresponding interface thereof is called a Uu interface, a Link between the Relay station and a base station (DeNB) to which the Relay station belongs is called a Backhaul Link (Backhaul Link), a corresponding interface thereof is called a Un interface, and a Link between a macro cell user (M-UE) and a base station directly served by the base station is called a Direct Link (Direct Link).
The backhaul link carries data and control signaling from the relay cell to the base station, and if the relay station is replaced by a micro-power base station or a home base station, the network elements corresponding to the two ends of the backhaul link are the micro-power base station and a core network, and the link between the home base station and a home base station gateway is collectively called the backhaul link for convenience of description.
According to business statistics, 97% of Chinese city residents have owned mobile phones and 35% of the Chinese city residents have owned smart phones by 2011. These users are using smart phones anytime and anywhere, with home, travel, work, public transportation, restaurants, shopping malls, and airports being the most frequent places to use smart phones.
The main uses of smart phone users in China cities for using smart phones include: product search, travel route consultation, restaurant lookup, social interaction, video sharing, gaming, and shopping with coupons, among others. 50% of chinese city smartphone users will often notice mobile advertisements and try to get more information. And 75% of Chinese city smart phone users will use the smart phone to socialize every week, and the social network will become a new viewpoint.
A typical application of a commercial place is also brought forward, the application is called a Location Based Service (LBS) shopping platform, typically, a Location Service provided by Shopkick company builds a bridge between the mobile phone world and the real world, a user can receive shopping and consumption in an interactive environment, the user earns points by checking in, and then walks into a retail store, a large department store, a movie theater, a restaurant and the like cooperating with the Shopkick, the Shopkick system can push various coupons for the user according to the Location of the user, and the key technology is to use an audio transmission technology similar to a microphone on a mobile phone to realize the Location of the user. A so-called push system can be thought of as a media server which pushes a certain multimedia service stream for a user after a certain wireless system is positioned that the user enters a specific area, and is not limited to coupons, video advertisements of merchants and the like; and a temporary network community can be built to provide information interaction for community users entering a specific area, such as direct mutual data transmission, images, audio, text information and the like between point-to-point users.
However, the LBS shopping platform can be used only by means of a backhaul link, so that higher cost is generated when the LBS shopping platform is used, which obviously hinders the popularization and application of the LBS shopping platform, and the development of the LBS shopping platform is limited by the reduction of audiences.
