Description
Technical field
The present invention relates to the data communications method in a kind of CDMA (Code Division Multiple Access, code division multiple access) communication system, particularly a kind of Packet data service provides method.
Background technology
The CDMA of current communications systems and be considered to the next generation communication system standard W-CDMA (Wideband-CDMA, in the broadband-CDMA), block data communication be by set up between terminal and the base station one to one continuously continuation method realize.But ideal situation is: continuing one to one between terminal and the base station lasts till always that grouping is exchanged for ends, and discharges this continue during the block data communication blocking period.So the capacity of communication channel can effectively be used, thereby save communication cost for the user.
During Packet data service, because the continuous connection state one to one of communication channel, make legacy packets data service in the cdma communication system bear excessive additionally opening and disappear, thereby reduced the service efficiency of channel capacity and forced the user to increase expense.In addition, to the data business, insert, increase gradually based on the demand of the data service of mobile communication as PC (personal computer) communication, internet.Most data services are carried out with the form of grouped data, and data are instantaneous rather than total appearance.That is to say that most data communication are block data communications.
In this case, have a kind of like this demand that increases day by day: interface structure is made under the prerequisite of minimum change in traditional cdma network, makes more user obtain data service with low expense.
Fig. 1 is the block diagram of terminal, base station and Radio Link in the mobile communication system.Radio Link among Fig. 1 is by carrying out the forward channel of transfer of data and form from the backward channel that terminal is transmitted to the base station from the base station to terminal.
Traditional CDMA mobile communication system has forward channel structure shown in Figure 3 and reverse channel architecture shown in Figure 2.Forward CDMA Channel has pilot channel, synchronizing channel, paging channel and is divided into primary channel and the forward traffic channel of auxiliary channel.Reverse CDMA channel comprises access channel and is divided into the reverse traffic channel of primary channel and auxiliary channel.
The bit rate of traditional two-way services channel is too low, so that Packet data service can not be provided.Guarantee that traditional two-way services channel has the approach that sufficiently high bit rate is used for Packet data service and is: the two-way services channel decomposing is become to bear traditional double to the primary channel of the identical function of Traffic Channel with for the auxiliary channel of the usefulness of block data communication.
Concerning Packet data service, calling should keep between base station shown in Figure 1 and terminal through forward direction and Reverse Fundamental Channel.Fig. 4 is to use the flow chart of the channel of traditional Packet data service.
Referring to Fig. 4, in step 411, use pilot channel, synchronizing channel, paging channel and access channel between terminal and base station, to set up basic call.Here, basic call two-way execution on forward direction and Reverse Fundamental Channel.In step 412, base station (terminal) determines whether the request of packet data transmission sends from terminal (base station).Under the situation that does not have the packet data transmission request, flow process jumps to step 417, keeps calling out on two-way primary channel.
When the packet data transmission request is arranged in step 412, then in step 413, auxiliary channel is used through forward direction (oppositely) primary channel notice terminal (base station) in base station (terminal), and in step 414, terminal (base station) is oppositely sending confirmation signal to base station (terminal) on (forward direction) primary channel.In step 415, grouped data is sent on two-way auxiliary channel fully.In step 416, in case grouped data sends/finishes receiving, two-way auxiliary channel just stops its operation.In step 417, on two-way auxiliary channel, keep calling out then.
Above-mentioned call establishment will be checked in the terminal aspect.Pilot channel, synchronizing channel and the paging channel of the controller of terminal in the forward channel of base station obtains the information of respective base station.Be used to insert of the message handling device generation of the information of this base station, convert signal to by baseband processor, and on Reverse Access Channel, send to the base station by terminal.
Message handling device analysis in the base station is ready to forward direction and Reverse Fundamental Channel from the access information that terminal receives, and is illustrated in the ready message of primary channel on the paging channel to the terminal transmission.The message handling device of terminal uses the two-way primary channel information acquisition forward fundamental channel that receives from the base station.Then, terminal on Reverse Fundamental Channel to base station transmit signals so that make the base station obtain Reverse Fundamental Channel.When the base station successfully obtains Reverse Fundamental Channel, then on forward fundamental channel, notify terminal this fact.When base station and terminal obtain two-way primary channel, then finish call setup.
After the call setup, terminal and the transmission/reception of base station waits grouped data exchange its information simultaneously on two-way primary channel on two-way primary channel.Although there is not transmission/receiving block data, calling should keep on two-way primary channel.Block data communication after the call setup is finished by repeating process shown in Figure 4.
Fig. 5 is the state transition graph based on the terminal of traditional CDMA standard.Referring to Fig. 5, when when state 511 powers up, terminal is set to initial condition 512.If terminal makes it regularly synchronous with the timing of system in initial condition 512, then state exchange is to idle condition 513.In idle condition 513, terminal can call attempt, and the base station sends the information of call attempt to terminal on paging channel, and terminal sends the message that pages reply to the base station.Then, terminal is set to system's access state 514.If terminal can not obtain paging channel message in idle condition 513, perhaps terminal turns to another neighbor base station from this base station in handover (handoff), and then terminal is returned initial condition 512.If the system that terminal is finished except that the reception of call attempt or calling confirmation signal in system's access state 514 inserts, then terminal turns back to idle condition.In contrast, if the reception that terminal is finished call attempt or called out confirmation signal in system's access state 514, then terminal enters traffic channel state 515.Traffic channel state 515 continues during Business Processing always.When Traffic Channel stopped its operation, terminal turned back to initial condition 512.
In traditional Packet data service, communication system should keep calling out on two-way primary channel, although have only the transmission/reception grouping of sparse (infrequent).For example, suppose grouped data about one minute to serve as transmissions/receptions in a second at interval, then communication system should with 59 seconds that data transmissions/reception time-out equates in maintenance login on two-way primary channel.In this case, the signal that sends on the two-way primary channel disturbs one other channel, thereby causes the waste of capacity of another the supported business in the cdma communication net.In addition, when more users required Packet data service, then for the user who only limits in the enterprising jargon sound communication of primary channel, the cdma mobile communication net became and more is difficult to insert.
Being used for the terminal of short grouping transmission/reception and the restriction that continues continuously between the base station has increased the expense of block data communication, and has hindered at cdma mobile communication block data communication extensively is provided on the net.Therefore, CDMA mobile communication system lags behind other communication system and is provided use with less aspect competitive.
Summary of the invention
The Packet data service that the purpose of this invention is to provide in a kind of CDMA mobile communication system provides method, is used for the only grouping transmission/reception period busy channel in the time of call setup.
