Description of drawings
Fig. 1 is the structural representation according to the described a kind of resource allocation apparatus of the utility model embodiment;
Fig. 2 is according to the described data-signal flow graph of the utility model embodiment;
Fig. 3 is the use schematic flow sheet according to the described TBF of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the structural representation for the described a kind of resource allocation apparatus of the utility model embodiment specifically comprises: transmission/receiver module, network transmission module, cross over circuit module, Temporary Block Flow controller.
Transmission/receiver module is made up of a plurality of transmission/receiving elements, is used for the transmission and the reception of data-signal;
Network transmission module is used for communicating with packet switching network;
The cross over circuit module is used between wireless connections and network connection data being shone upon;
The Temporary Block Flow controller is used for reaching possible request monitors from the extra Temporary Block Flow of travelling carriage according to setting up and safeguard Temporary Block Flow from the foundation request of network and travelling carriage reception.
Described resource allocation apparatus comprises a plurality of transmissions (Tx) and receives (Rx) unit, one is used for the network transmission module of packet switching network (GPRS) communication and is used for the cross over circuit module of mapping (enum) data between wireless connections and network are connected, described network transmission module carries out transfer of data by cross over circuit module and transmission/receiver module, and Temporary Block Flow (TBF) controller is according to setting up and safeguard Temporary Block Flow from the foundation request of network and travelling carriage reception.Temporary Block Flow controller in the equipment described in the utility model at first is that an independent travelling carriage distributes several TBF, and constitutes message, to set up TBF, also to possible request monitors from the extra TBF of travelling carriage.
In the utility model, with a data-signal flow graph represent to transmit and receive data in the resource allocation apparatus course of work of signal, with reference to figure 2.
With a dispensing device and a receiving system illustrative is communicating pair.These two devices can both send and receive, but title wherein is meant their original functions in packet switching communication connects.In the present embodiment, dispensing device and receiving system are operated in the multi-user environment, wherein have definite Management Information Base control channel to use for a large number of users, and can give each connection with the traffic channel assignment of special use as required therein.
Among Fig. 2, the beginning that packet switching communication of 201 expressions connects, this connection sends its indication that begins that need set up a connection by dispensing device and shows beginning, shown in the unidirectional arrow above in 201, this process also usually occurs on the Common Control Channel, shown in the four-headed arrow below in 201, be on common signal channel or dedicated channel, to carry out some other information exchange subsequently.Be responsible for distributing the device of private communication channel to distribute at least one dedicated channel for the needs that connect, four-headed arrow in 201 need to represent two-way services to confirm this distribution, perhaps should carry out this distribution according in the equipment which, actual assignment messages can appear at any direction.As required, private communication channel can comprise the channel of data channel, control channel or other kind.
Shown in 202, actual transmitted in packets occurs on the private communication channel.To communicate to connect in order describing generally, to suppose that the distribution of private communication channel is just remained valid as long as transmitter has remaining grouping to send.In certain stage, dispensing device may send in the dedicated channel with the messaging parameter that is different from existing channel.According to the utility model embodiment, continue to use the dispensing device of existing dedicated channel to send an indication 203 that distributes other dedicated channel about needs.
Shown in 204, carry out the configuration of other dedicated channel.Shown in 205,, on channel, proceed grouping and send by distributing new resource to set up after other efficient channel distributes.If dispensing device need send in the dedicated channel with the messaging parameter that is different from existing channel once more, then can repeating step 203 to 205.Present embodiment does not limit from going on foot 203 numbers of repetition to step 205.Shown in 208, after any existing connection, grouping storehouse are used up, can be according to any known procedures with this connection termination.
A kind of resource allocation apparatus described in the utility model, setting up at least one between the travelling carriage on the packet wireless business of telecommunication system and network is connected and is used for sending at least one data flow, and be that a definite direction of transfer distributes the Temporary Block Flow (TBF) of at least two whiles, be sent to few data flow to connect described at least one.Wherein, described at least one be wirelessly connected on Temporary Block Flow of formation on the Packet Data Channel.Below just the use of TBF is described in further detail.
