Abstract
A routing device in a relay system based on a cellular system according to the invention is proposed. The routing device comprises a source user terminal sending the connection request to a destination user terminal through a relay station, a destination client determining whether a source client has a non-cellular system wireless interface shared with the destination client according to the connection request. If the destination client determines that the source client has the non-cellular system wireless interface shared with the destination client, the destination client directly establishes the data connection to the source user terminal through the non-cellular system wireless interface; if the destination client determines that the source client does not have the non-cellular system wireless interface shared with the destination client, the destination client establishes the data connection to the source user terminal by the relay station through the cellular system wireless interface. The routing device also comprises a relay station.
Description
Technical field
The present invention relates to moving communicating field, more specifically, relate to a kind ofly based on method for routing in the relay system of cellular system and equipment, in order to promoting the communication efficiency in the relay system, and break the capacity bottleneck that the base station air interface is caused.
Background technology
In order to give cellular system of future generation-effectively as WiMax/WiBro (broadband wireless access/WiMAX) etc.-increase throughput, and expanding system coverage, the 802.16j task groups of IEEE, 3GPP LTE, WWRF etc. have proposed to use relay system to be issued to the draft of above-mentioned purpose in effective cost control.The present invention relates generally to the relay system in the wireless cellular system of future generation, especially the relay system of WiMax/WiBro.
Existing relay system communication mode is as shown in Figure 2: two users of same sub-district, no matter whether they belong to same relaying, all need to carry out forwarding of data through the base station.When the first half of Fig. 2 is two telex networks of same relaying, data flow the path of process; When the latter half is two telex networks of different relayings, data flow the path of process.
There is following technical problem in the prior art.
Distance between two users is closer, as when being positioned at same relaying or adjacent relaying, this communication mode that carries out forwarding of data through the base station comparatively poor efficiency that seems.Moreover, in comprising the sub-district of trunk desk, because all communication all will be through the base station, the air interface of base station just becomes the bottleneck of system naturally.No matter trunk desk can be supported great throughput to the user, and it is the upper limit of network capacity that the air interface of base station can provide throughput.For the capacity that can bring into play relaying greatly and brought promotes, must try every possible means to overcome the bottleneck that air interface caused of base station.
In order to break the bottleneck that air interface caused of base station, and improve the efficient of communication, the present invention has provided the communication mode that is called " shortcut route ".In the shortcut route, two interior users of a relaying scope that exist together can pass through other frequency range (as ISM band) direct communication, or transmit data by relaying.The user who is in the adjacent relaying scope can communicate by the forwarding between the relaying.Compare traditional communication mode, the shortcut route not only can promote communication efficiency, and also having overcome all flows to a great extent must be through the bottleneck that air interface caused of base station.
