The invention relates to a method for transmitting data records to mobile terminals (414, 415, 416) which are connected via a radio network (4) to a data server (1) connected to a data network (2), by means of which the data records are transmitted via the radio network (4) can be transmitted to terminals (414, 415, 416) located in a radio cell (41) of the radio network (4) as a broadcast signal or alternatively as an individual signal specifically directed to one or more terminals (414, 415, 416), wherein a total signal transmitted to the radio cell (41) includes a corresponding broadcast signal portion (412) and a corresponding individual signal portion (413), comprising the steps of: a) identifying the terminals (414, 415, 416) within the radio cell (41) by the Data server (1), b) determining a preferred Broadcastsignalteilfaktors for the total signal by the data server (1) on the basis of one of the within the radio cell (41) ide c) transmitting a first portion of the data records in the broadcast signal portion (412) of the total signal and a second portion of the data records in the individual signal portion (413) of the total signal from the data server (1) to the terminals (414 , 415, 416), wherein the broadcast signal portion (412) of the total signal transmitted to the terminals (414, 415, 416) is determined based on the determined preferred broadcast signal sub-factor. The invention is characterized in that the terminals (414, 415, 416) identified in the radio cell (41) are each assigned a user profile and the contents of the data records transmitted in the broadcast signal part (412) are compiled as a function of the information stored in the user profiles becomes.
The invention relates to a method for transmitting data records to mobile terminals, which are connected via a radio network to a data network connected to a data server, by means of which the records via the wireless network located in a radio cell of the wireless network terminals as a broadcast signal or optionally as an an or several terminals specifically directed individual signal can be transmitted,
wherein a total signal transmitted in the radio cell contains a corresponding broadcast signal part and a corresponding individual signal part, comprising the steps:
a) identifying the terminals located within the radio cell by the data server,
b) determining a preferred broadcast signal sub-factor for the overall signal by the data server on the basis of a data demand requested by the terminals identified within the radio cell,
c) transmitting a first portion of the records in the broadcast signal portion of the overall signal and a second portion of the records in the individual signal portion of the total signal from the data server to the terminals, wherein the broadcast signal portion of the transmitted to the terminals total signal is determined based on the determined preferred broadcast signal sub-factor.
Such a method is known from US 2013/0051331 A1 known.
In the known method, a data server transmits data records via a LTE network (Long Term Evolution network) to mobile terminals, such as smart phones or laptops, using an EMBMS protocol (Evolved Multimedia Broadcast Multicast Service Protocol). In the case of EMBMS, the data is transmitted by a time-multiplex method in which a broadcast and a unicast signal are transmitted in the same frequency channel but at different time intervals.
In the known method, by using the EMBMS protocol, the data sets are transmitted to the terminals connected to a base station of the LTE network via an overall signal composed of a broadcast signal part and a unicast signal part. The data server determines for this purpose a preferred Broadcastsignalteilfaktor for the emitted total signal. In the context of the present description, the broadcast signal partial factor is to be understood as the temporal component of the overall signal which is favorably to be used for the transmission of data records as a broadcast signal. Typically, that portion is determined for this purpose, which is not needed to send records that must be sent as a mandatory individual signal. In the known method, the data server takes into account the contents requested by the terminals for determining the preferred broadcast signal sub-factor and, in particular, how many terminals have requested an identical content that can be transmitted via broadcast. By transmitting identical contents via the broadcast signal part of the overall signal, the corresponding terminals no longer need to be addressed via the unicastsignal part, so that the overall limited available transmission capacity of the base station can be used efficiently. The data server, based on the determined preferred broadcast signal sub-factor, tunes the proportion of the broadcast signal portion in the overall signal, i. he assigns the Broadcastsignalteil the corresponding time periods for the transmission in the frequency channel.
As is known, in the case of a broadcast transmission at a specific time, only a single, shared content can be transmitted simultaneously to the corresponding terminals, whereas different contents can be transmitted to different terminals in the context of the unicast transmission. As a result, the known method is severely limited, especially in situations in which many different contents are requested by the terminals at the same time. In such a scenario, only a few of the contents to be transmitted are identical, so that consequently only a correspondingly small part can be transmitted via the broadcast signal part of the overall signal. Therefore, a large part of the content must therefore necessarily be transmitted in the unicast signal part, which however can often not be guaranteed due to the limited total available transmission capacity of the radio network. A part of the terminals, which would ideally have to be supplied with content via the unicastsignal part, must therefore also be addressed via the broadcast signal part of the overall signal if the available total transmission capacity is exceeded. However, this will provide the users of these devices with content that may not be in their interests.
From the US 2013/0051331 A1 It is also known that when determining the preferred broadcast signal factor, the total number of terminals connected to a base station of the radio network can also be taken into account. In this way, for example, radio cells of the radio network can be identified, in which the total transmission capacity is exceeded with high probability and in which therefore a supply of terminals via the Broadcastsignalteil is particularly useful. However, this does not make it possible to match the contents transmitted via the broadcast signal part to the interests of the corresponding users.
It is the object of the present invention to further develop a generic method such that the contents transmitted via the broadcast signal part better correspond to the interests of the respective users of the terminals.
This object is achieved in conjunction with the features of the preamble of claim 1, characterized in that the identified in the radio cell terminals each have a user profile is assigned and the content of the data transmitted in the broadcast signal part data sets is compiled depending on the information stored in the user profiles.
Preferred embodiments are subject of the dependent claims.
The method according to the invention makes it possible to variably compile the content transmitted via the broadcast signal part as a function of the information stored in the user profiles. As a result, in comparison with the method known from the prior art, a larger number of users can be supplied with content relevant to them via the broadcast signal part. For this purpose, the data server identifies, for example via the IP addresses, the terminals located within a radio cell of the radio network and composes the content transmitted via the broadcast signal portion of the overall signal in accordance with the interests of the respective users. As a result, all users, in particular in the case of insufficiently available total transmission capacity of the radio network, can be provided with content corresponding to their interests. The data server identified in a radio cell identified terminals, such as smartphones or laptops, associated user profiles can refer to it in different ways.
In an alternative embodiment of the method according to the invention, provision is made for the user profiles to be obtained from the data server via the connected data network. The data server can thus, for example, obtain the user profiles via the Internet from third-party providers, such as Facebook, google, or last.fm. He can retrieve the access data required for this purpose, for example via a unicast signal from the terminals. The access data may be for this purpose e.g. previously entered by the user on the terminal or stored in this. Of course, it is also possible for the user profiles, once obtained via the data network, to be stored by the data server for future use.
In a preferred embodiment of the method according to the invention, it is provided that the user profiles are created by the data server. As a result, the access data of the user can be completely dispensed with. By way of example, the data server can create a user profile corresponding to each terminal via the IP addresses known to it and the contents requested by the respective terminals.
In a further preferred embodiment of the method according to the invention, it is provided that the terminals located within the radio cell are recognized by a recognition system independent of the radio network, by means of which identification information about the terminals located within the radio cell is transmitted to the data server, so that those located within the radio cell Terminals are identifiable by this. This embodiment is particularly advantageous if the transmission capacity of the radio cell is no longer sufficient to identify all located in the radio cell terminal via its IP address. In such a case, for example, a vehicle - representative of the femtocell or the terminals connected to it - which newly enters such a radio cell, can advantageously be identified by a GPS system independent of the radio network, which then uses the data server informed about the entry of the vehicle into the radio cell. In this way, the vehicle can be identified by the data server and a correspondingly assigned user profile can be taken into account accordingly when compiling the content transmitted via the broadcast signal part into the radio cell.
Further features and advantages of the invention will become apparent from the following specific description and the drawings.
1 : An illustration of an embodiment of the method according to the invention.
1 shows an illustration of an embodiment of the method according to the invention. In 1 is a data server 1 seen coming from a Broadcast Multicast Service Center (BM-SC) 11 and a content server 12 is constructed. The content server 12 is doing a data network 2 connected with a third party 21 connected is. In 1 is also shown that the BM-SC 11 over a base station 411 a radio cell 41 on from a broadcast signal part 412 and an individual signal part 413 constructed total signal in the radio cell 41 that has been generated using an evolved multimedia broadcast multicast service (EMBMS) protocol. The broadcast signal part 412 the total signal is sent to the terminals 414 . 415 , the individual signal part 413 to the terminal 416 transmitted. The individual signal part 413 is in the in 1 illustrated embodiment, a unicast signal part. In 1 is also shown to be a recognition system 5 the terminals 414 . 415 . 416 , via GPS signals 51 . 52 . 52 within the radio cell 41 of the LTE wireless network 4 recognizes and a recognition information to the content server 12 transmitted. The content server 12 identifies the terminals by means of the recognition information 414 . 415 and 416 and realizes that these are in the radio cell 41 are located. The content server 12 refers to the terminals 414 . 415 and 416 associated user profiles from the third party 21 , Based on the information stored in the user profiles, the content server in the 1 illustrated embodiment that the the terminals 414 and 415 assigned users have a similar taste in music, and determined in coordination with the BM-SC 11 , via the base station 441 it is known that the terminal 416 has requested an e-mail record that is only in the Unicastsignalteil 413 the total signal can be transmitted, a preferred Broadcastsignalteilfaktor. In the in 1 illustrated embodiment, determine the content server 12 and the BM-SC 11 as Broadcastsignalteilfaktor those periods of the total signal, which are still available for a broadcast transmission in addition to the mandatory for the transmission of the e-mail record time periods. The content server 12 then sets music records whose content matches the taste of music of the users of the terminals 414 and 415 correspond and in the determined, still available periods of time to the terminals 414 and 415 can be transferred together. The collected records are transferred by the content server 12 to the BM-SC 11 that in the broadcast signal part 412 the total signal, which is determined by the still available for the broadcast transmission periods, to the terminals 414 and 415 transmitted. At the same time, the BM-SC transmits 11 in the individual signal part 413 the total signal from the content server as well 12 previously transmitted e-mail record to the terminal 416 ,
Of course, the embodiments discussed in the specific description and shown in the figures represent only illustrative embodiments of the present invention. A broad range of possible variations will be apparent to those skilled in the art in light of the disclosure herein. For example, the individual signal part of the overall signal does not necessarily have to be a unicast signal part. On the contrary, any individual signal directed specifically to one or more terminals can be used for this purpose. The individual signal part can therefore in particular also be a multicast signal part, with which a specific group of terminals can be addressed via their IP addresses and simultaneously supplied with a single, common content. The method according to the invention can be initiated by different events. For example, For example, an actual increase in the traffic load can be detected based on the incoming requests. However, it is also possible to anticipate a high traffic load based on a high density of mobile devices that is actually detected or from third-party context information, e.g. from traffic jams, is derived. Such a density of mobile devices can also be anticipated from historical data.
