Description
Technical field
The present invention relates to single time slot adaptive multiuser speech business (VAMOS, Voice services over Adaptive Multi-user channels on One Slot) in user switch access technology, particularly relate to a kind of user of raising switch access success rate method and apparatus.
Background technology
VAMOS is third generation partner program (3GPP, The3rd Generation Partnership Project) global system for mobile communications (GSM that determines, Global System for Mobile Communications) for the evolution scheme being polymerized sublayer (CS, Convergence Sublayer).The general principle of VAMOS is the voice transfer simultaneously realizing two users under a channel, the Corticofugal Modulation of Somatosensory scheme of VAMOS is self adaptation quarternary phase-shift keying (QPSK) (AQPSK, Adaptive Quadrature Phase Shift Keying), up modulation scheme is the superposition of two Gaussian-filtered minimum shift keying (GMSK, Gaussian Filtered Minimum Shift Keying) signal.To the support of new training sequence set whether different and according to the demodulation ability of terminal, terminal is divided into does not support VAMOS(VAMOS not supported Terminal) tradition (legacy) terminal, VAMOS I terminal, VAMOS II terminal; Wherein, VAMOS I and the new training sequence code set 2(TSC Set2 of II terminal support, Training Sequence Code Set2), support the transmission etc. of mobile slow associated control channel (shifted SACCH, Slow Associated Control Channel).
At present, the networked users of gsm system are in the majority with legacy terminal, the antijamming capability of legacy terminal also divides several rank: non-single antenna interference cancellation (the NON SAIC of noiseless rejection ability, Non Single Antenna Interference Cancellation) terminal and have single antenna interference cancellation (SAIC, the Single Antenna Interference Cancellation) terminal of interference rejection capability.In fact, often have a lot of terminal to there is the situation of oneself actual physics layer ability rating of not reporting, therefore, base station needs to detect the ability of terminal, and what the physical layer ability of final terminal self detected with base station is as the criterion.
Because VAMOS carries out voice transfer for two users simultaneously, so, need to match to user terminal, the terminal type at present for matching, main consideration is several as follows:
NON SAIC terminal: terminal to report is NON SAIC terminal, base station is detected and is finally defined as NON SAIC, this type terminal is noiseless rejection ability;
MUTE SAIC terminal: terminal to report is NON SAIC terminal, base station is defined as SAIC terminal after detecting;
Single antenna interference cancellation automatic frequency controls (SAIC AFC, Single Antenna Interference Cancellation Automatic Frequency Control) terminal: terminal to report is SAIC terminal, base station is defined as SAIC AFC after detecting, and but this type terminal has SAIC ability there is frequency deviation problem;
SAIC terminal: terminal to report is SAIC terminal, base station is defined as SAIC terminal after detecting;
VAMOS I terminal: support training sequence set TSC SET2, do not support the joint-detection of physical layer;
VAMOS II terminal: support training sequence set TSC SET2, support the joint-detection of physical layer.
The priority relationship considered during pairing, is shown in Table 1; Wherein, user0 and user1 is the terminal that will match.
| Pairing priority | User0 | User1 |
| 1 | SAIC、MUTE SAIC | VAMOS I |
| 2 | SAIC、MUTE SAIC | VAMOS II |
| 3 | VAMOS I | VAMOS II |
| 4 | SAIC、MUTE SAIC | SAIC、MUTE SAIC |
| 5 | VAMOS I | VAMOS I |
| 6 | VAMOS II | VAMOS II |
| 7 | SAIC AFC | VAMOS I |
| 8 | SAIC AFC | VAMOS II |
| 9 | SAIC AFC | SAIC AFC |
| 10 | SAIC AFC | SAIC |
| 11 | NON SAIC | VAMOS II |

Embodiment
The basic thought of the embodiment of the present invention is: when the switching of VAMOS user terminal is initiated in base station, sending the burst position of to be switched terminal FACCH, and the gross power of armed to be switched terminal with pairing terminal is heightened by adjustment Corticofugal Modulation of Somatosensory parameter value simultaneously.
First, should understand business burst and control burst: usually, logic channel is divided into two large class--Traffic Channel (TCH, Traffic Channel) and control channel (CCH, Control Channel), wherein, Traffic Channel is for transmitting the speech after coding or customer data, on uplink and downlink channel, point-to-point mode is propagated; Control channel is for transmitting signaling or synchrodata.
FACCH works in dedicated mode, in business procedure when there being signaling message to transmit, can use a TCH time slot temporarily and be used as FACCH, this situation occurs when switching, be that speech or data time by using 20ms transmits signaling, this situation is called as frame steathily.
Below for Traffic Channel, business burst is described.Fig. 1 is current traffic channel measurement report periodic structure schematic diagram, and as shown in Figure 1, in TCH, a measurement report cycle duration 480ms, comprises four multi-frames in a measurement report, and each multi-frame duration 120ms, comprises 26 business burst in each multi-frame.When a handover occurs, when namely frame is stolen in generation, as shown in Figure 1, front four burst in multi-frame 1 are stolen frame and becomes FACCH, from the angle of terminal, when switching, base station is stolen frame by four burst and is sent FACCH; In Fig. 1, F represents FACCH, and T represents TCH.
The embodiment of the present invention, from burst aspect, is considered, when switching initiation, to carry out power control in burst aspect.The scene switched comprises following two kinds of situations:
Scene 1: because VAMOS is that two users are at the enterprising lang sound business of same channel, for user1 and user0, user1 is to be switched terminal, user0 is the object pairing terminal being about to pairing, when switching initiation, common way is switched on the wireless channel of user0 by the intra-cell user user1 that changes commanders, and makes user1 and user0 form a VAMOS to (pair); In the process switched, for be switched user user1, must have issuing of chain of command signaling switching within cell, and the transmission of this signaling is the data interference that will be subjected to user user0, this interference is likely control signal, is also likely voice.If the power that user1 launches is too low, or do not carry out the consideration of some power aspects, then user1 can the signaling that issues of decoding network side, causes and matches unsuccessfully.
Scene 2: for the VAMOS pair formed, due to the movement of two users or the change of extraneous wireless environment, current pair relationhip, from the requirement of wireless transmission, has been not suitable for maintaining this pair relationhip, therefore, network needs pair relationhip to remove.Here, still for user1 and user0, user1 is to be switched terminal, first wife when user0 is solution pairing is to terminal, common way is switched on a new reasonable channel of radio condition by user1 by handover operation, for to be switched user user1, issuing of chain of command signaling switching within cell must be had, the transmission of this signaling is the data interference that will be subjected to user user0, this interference is likely control signal, also be likely voice, if the power that user1 launches is too low, or do not carry out the consideration of some power aspects, then user1 can the signaling that issues of decoding network side, cause handoff failure.
Below in conjunction with drawings and the specific embodiments, the enforcement of embodiment of the present invention technical scheme is described in further detail.
Fig. 2 is the method flow schematic diagram that the embodiment of the present invention one improves that user switches access success rate, and as shown in Figure 2, the present embodiment improves the method that user switches access success rate, comprises the following steps:
Step 201: base station is initiated VAMOS user terminal and switched;
Step 202: sending the burst position of to be switched terminal FACCH, adjustment Corticofugal Modulation of Somatosensory parameter value, heightens the gross power of armed to be switched terminal with pairing terminal simultaneously.
Wherein, described pairing terminal can for when VAMOS matches object pairing terminal, also can for VAMOS separate match time first wife to terminal; Described armed to be switched terminal and the gross power of pairing terminal are exactly the gross power that base station will be transmitted to be switched terminal and pairing terminal.
Described Corticofugal Modulation of Somatosensory parameter, represent with alpha, for adjustment is transmitted to the relative power decibel difference of to be switched terminal and pairing terminal, such as: the power P 1 being meant to the be transmitted to be switched terminal x dB higher than the power P 0 being transmitted to pairing terminal of alpha=x, the main purpose of adjustment alpha value is: better resist another user in VAMOS pair to make to be switched terminal and match the interference of terminal, therefore, the power being transmitted to be switched terminal should be greater than the power of pairing terminal, namely alpha should be greater than zero, such as, alpha=2 is set, namely the power P 1 being transmitted to be switched terminal matches well the high 2dB of power P 0 to terminal, the main purpose increasing gross power P is: in order to promote the suppression of to be switched terminal Noise and Interference to external world.
Two terminals of actual participation pairing, the ability of its physical layer may have larger difference, as listed in Table 1, therefore, for the terminal of particular type and anti-interference requirement, the value of modulation parameter alpha can be set during concrete enforcement, switch effect to reach best.
Described adjustment Corticofugal Modulation of Somatosensory parameter value, the gross power key of armed to be switched terminal with pairing terminal is highly specially: when Base Transmitter meets the power decibels difference that Corticofugal Modulation of Somatosensory parameter alpha requires to be switched terminal and the power of pairing terminal simultaneously, heightens being transmitted to be switched terminal and matching the gross power of terminal.Such as, as alpha=2, when the power P 1 being transmitted to be switched terminal matches well the power P 0 high 2dB to terminal, the gross power being transmitted to be switched terminal and pairing terminal is heightened.
Preferably, in order to reach optimum efficiency, describedly by armed to be switched terminal and the gross power key of pairing terminal highly can be: the maximum armed to be switched terminal and the gross power of pairing terminal being adjusted to base station transmitting power.
To be switched terminal sends the burst position of FACCH as shown in Figure 3, Fig. 3 is the embodiment of the present invention one base band (BB, Baseband) single plate structure schematic diagram, when base station initiate user switch time, in a multi-frame, will the speech of 20ms or data time be used to send FACCH, shown in Fig. 3, when switching, base station is stolen frame by four burst and is sent the position that F position in FACCH, Fig. 3 is business burst transmission FACCH; Accordingly, the position of each F in figure 3, adjustment Corticofugal Modulation of Somatosensory parameter alpha value, heightens being transmitted to the gross power of to be switched terminal with pairing terminal simultaneously.
Because mobile subscriber is in whole communication process, on average only have the time of 40% for call, other mosts of the time do not transmit speech information.Therefore, base station can adopt DTX, to save system resource; Wherein, DTX is divided into up DTX and descending DTX.DTX, by the wireless transmission of restriction garbage, reduces the generation of interference, individually can use in upstream or downstream.When network side opens descending DTX, when not having speech information, the pairing corresponding business burst position of terminal, what base station sent is mute frame.
Have transmitting power owing to sending pairing terminal mute frame, so, send to be switched terminal FACCH farthest can hide the interference of the pairing terminal of VAMOS pair in this time period, therefore, the success rate switched at this one-phase can significantly improve.But actual conditions are when initiating switching command in base station, the mute frame of pairing terminal can not be detected immediately, but when needing wait transmission pairing terminal mute frame to be detected, then send to be switched terminal FACCH, so just have one to postpone to produce, the time of wireless access can be increased.If this delay duration exceedes the wireless access overtime timer of end side, then terminal can abandon this switching, causes handoff failure.In order to prevent the generation of this type of situation, a preset duration can be set, if before preset duration terminates, the mute frame sending to pairing terminal can be detected, then send the FACCH of to be switched terminal in the mute frame position sending pairing terminal; If the mute frame sending to pairing terminal do not detected in preset duration always, then, when preset duration terminates, send to be switched terminal FACCH immediately.
Fig. 4 is the method flow schematic diagram that the embodiment of the present invention two improves that user switches access success rate, and as shown in Figure 4, when network side opens descending DTX, the present embodiment improves the method that user switches access success rate, comprises the following steps:
Step 401: base station is initiated VAMOS user terminal and switched;
Step 402: detect the mute frame sending to pairing terminal, if the mute frame sending to pairing terminal detected in Preset Time, then performs step 403, otherwise, perform step 404;
Step 403: send to be switched terminal FACCH in the mute frame position sending pairing terminal, perform step 405 afterwards;
Step 404: at the end of preset duration, sends to be switched terminal FACCH immediately;
Concrete, in preset duration, if be sent in the moment of to be switched terminal FACCH, immediately at the TCH eating dishes without rice or wine to run into pairing terminal transmission, then postpone the transmitting of FACCH, etc. the mute frame sending to pairing terminal to be detected, until the mute frame sending to pairing terminal detected, launch FACCH in the position of the transmitting mute frame sending pairing terminal.Otherwise, at the end of preset duration, send FACCH immediately
Step 405: sending the burst position of to be switched terminal FACCH, adjustment Corticofugal Modulation of Somatosensory parameter alpha value, heightens the gross power of armed to be switched terminal with pairing terminal simultaneously.
