Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of concurrent service processing method and device.
Background technology
Along with popularizing of TD intelligent terminal, various colourful application program of mobile phone arise at the historic moment.The client softwares such as QQ wherein, Fetion, microblogging often carry out the backstage and automatically move.And these clients are to keep to be connected connection with server, adopted the heartbeat packet testing mechanism, for example the QQ cell-phone customer terminal every tens seconds or a few minutes can be automatically and the webserver carry out heartbeat packet alternately, so just cause the intelligent terminal user often to be in the connection of packet data domain business (hereinafter to be referred as the PS business), when if the user connects in these application programs, dial or receive calls, voice and packet data concurrent service will occur.
Voice and packet data concurrent service is the distinct characteristic of 3G, and namely a plurality of circuit hosting domain business (hereinafter to be referred as the CS business), PS business occur simultaneously.Voice and packet data concurrent service has also brought a series of problem when enriching user's experience.When the most outstanding was exactly CS business and PS service concurrence, the PS business can produce abnormal conditions, took more resource, thereby caused a series of faults such as CS business one-way voice, call drop, and the user is caused very bad perception.
The all devices producer of present TD-SCDMA network is for the two schemes that carries of voice and packet data concurrent service.A kind of scheme is that voice and packet data concurrent service is based upon on the R4 carrier wave, and to take 4 BRU(be code channel up for speech business RAB, data service RAB and 3.4K signaling SRB), descendingly also take 4 BRU; Another kind of scheme is that voice and packet data concurrent service is based upon on the HSDPA carrier wave, up at least 4 BRU, the data service RAB use HS-PDSCH in descending voice and packet data concurrent service, speech business RAB and two DPCH channels of 3.4K signaling SRB use of taking.
The assessment of process to the actual performance of TD-SCDMA network, all there is comparatively serious defective in above two kinds of voice and packet data concurrent service based Carrying Schemes.
The first, voice and packet data concurrent service R4 carriers carry scheme: the TD-SCDMA network of China Mobile is in order to guarantee the downloading rate of PS business, R4 number of carriers in residential quarter will be less than the HSDPA number of carriers, for example for the outdoor grand station of S333, be generally the R4 carrier wave be the R4 carrier wave with the ratio of HSDPA number of carriers: HSDPA carrier wave=1:2, for indoor Micro-cell, general R4 carrier wave is the R4 carrier wave with the ratio of HSDPA number of carriers: HSDPA carrier wave=2:4.By the complaint statistics to existing network, find to adopt the network of this scheme, in the residential quarter that intelligent terminal is relatively concentrated, the complaint of up single-pass is high.Through on-the-spot test, find because the BRU that each voice and packet data concurrent service user uplink of this scheme takies is more than common AMR user's twice, although so this residential quarter number of users and few, but because the user's accounting that has voice and packet data concurrent service is larger, caused voice and packet data concurrent service seriously to tie up the physical resource of R4 carrier wave, up code resource utilization is too high.Too high code resource utilization has caused again up ISCP to disturb to be increased, and finally forms even call drop of up single-pass.
The second, voice and packet data concurrent service HSDPA carriers carry scheme: when voice and packet data concurrent service occurs, speech business RAB1 and data service RAB2 are carried on the HSDPA carrier wave simultaneously, and RAB1 and signaling SRB generally are mapped in the TS6 channel, and RAB2 is carried on HS-PDSCH channel: TS3, TS4, TS5.This scheme extensively adopts on the network of the TD-SCDMA of the manufacturers such as middle Xinghe Datang.Carry out the assessment of network quality through the city, Guangdong that the emerging equipment of centering covers, find that the voice and packet data concurrent service call drop that this mechanism causes is comparatively serious.Voice and packet data concurrent service is based upon and causes the high reason of cutting off rate to have on the HSDPA carrier wave:
1) in voice and packet data concurrent service, data service is carried by HS-PDSCH, data volume is very little, so scheduling times is less, when this user is scheduled once in a while, due to the interval of HS-SCCH greater than the GAP cycle, this moment, HS-SCCH can with initial maximum power transmission, cause this user AMR business to be disturbed and call drop by HS-SCCH;
2) during voice and packet data concurrent service, because the PS service traffics are very little, so up DCH channel needs reduction of speed to arrive than low rate, carry out simultaneously RB and reshuffle, this has increased and has gone offline/risk of dropped calls;
3) all TD-SCDMA equipment producer in the industry during voice and packet data concurrent service, if the PS business goes offline, will also discharge the AMR business of normal talking simultaneously, cause the AMR business in voice and packet data concurrent service to be forced to discharge;
4) disturb from the neighbor cell co-frequency co-time slot.
As known from the above, all there is the not good drawback of voice call perception in two kinds of present voice and packet data concurrent service based Carrying Schemes.
