Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of channel adjusting method.
Background technology
In mobile communication system, carry accordingly according to the terminal traffic type selecting, wherein in most cases adopt private resource to carry the business of terminal, as voice, data download, multimedia, stream business etc.In the maintenance process of terminal traffic, because the complexity of wireless environment is for the service quality (Qos, Quality of Service) that guarantees that terminal is applied for, usually need the link circuit resource of terminal traffic is adjusted accordingly, to guarantee the Qos of utilization ratio of wireless resources and terminal.
According to the characteristics of 3G communication, when terminal initial inserts, need and Radio Resource control (RRC, Radio Resource Control) connection that network side is set up its signaling of carrying.After the RRC of terminal connection was based upon on the dedicated channel (DCH, Dedicated Channel), this moment, terminal promptly was in the DCH state.Behind the associative operation of finishing authentication to this terminal, service request identification, the type of this requested service of terminal and Qos are clear and definite.In setting up the process of service bearer, be a reconfiguration course to original link.For the Radio Link of this terminal, after reshuffling, should can carry simultaneously the signaling and the business of this terminal, and the Radio Link during with its signaling of carrying is inconsistent.
Because above-mentioned Radio Link there are differences before and after reshuffling, so need aloft to go up, network side and terminal equipment should adopt this configuration simultaneously at some fixed time points, if the time point that both sides use is inconsistent, then must cause out of touch mutually, thereby cause communication disruption.Behind accessing terminal to network, in communication period, because the variation of business datum amount or the variation of wireless quality, Qos for save radio resources or assurance terminal, need carry out the quality adjustment to original Radio Link, also need the Radio Link of terminal is reshuffled, there is identical attribute in the Radio Link characteristic after reshuffling with Radio Link characteristic in the above-mentioned access procedure.
Characteristics of above-mentioned application are exactly that end is a designated cell, under the control of same base station (NodeB), because professional variation, carry out the adjustment of DCH-DCH, need reshuffle existing link layer, maintenance in order to communicate by letter simultaneously, the new link after reshuffling be interface termination equipment and network side use synchronously aloft.
In order to address the above problem, at present in the 3GPP agreement, realize by the method for using synchronized reconfiguration, introduce the notion of activationary time point usually, using new link at the same time simultaneously by activationary time point coordination terminal equipment and network side in the synchronized reconfiguration process.
In concrete wireless network environment, because its complexity and many existence through disturbing, the setting of activationary time point is an important factors.Figure one is the access procedure at certain terminal primary circuit territory of certain designated cell under certain specific base control, it is described in detail in the at present existing scheme, after the RRC of terminal in access procedure connection is based upon DCH, to set up in the process in follow-up business, the adjustment process of DCH-DCH is specific as follows:
101, terminal is when inserting, and network based certain strategy connects the RRC of this terminal and is based upon on the DCH;
102, after RRC connects foundation, terminal high level (layer three) by and core net (CN) alternately, at radio network controller (RNC, Radio Network Controller) and the interface between the CN (Iu interface) the Iu signaling of setting up this terminal connect, and connect in conjunction with the RRC of air interface, finish UE and CN alternately;
103, CN requires RNC to set up corresponding RAB for this terminal equipment again;
104 and 105, RNC sets up this professional Iu interface bearing of carrying according to the requirement of CN at the Iu interface;
106, RNC is according to the requirement of CN, and the interface (Iub interface) by RNC and base station (Node B) requires the Node B existing Radio Link of this terminal of interface synchronized reconfiguration aloft;
107, Node B is according to the requirement of RNC, prepare corresponding resource and carry out pre-configured, finish on request resource pre-configured after, to the RNC success response;
108 and 109, RNC sets up this professional Iub interface carrying of carrying at Iub interface;
110, RNC calculates the activationary time of this link according to certain strategy, at the appointed time puts by order notice NodeB and enables this link;
111, RNC notice terminal equipment is configured according to new requirement, comprises the characterisitic parameter of new bearer and the activationary time point of this link of use in this order;
112 and 113, after UE receives the configuration order of RNC, reply the affirmation information that data are correctly received to RNC, the requirement according to configuration order is configured then; After configuration is finished, judge whether the activationary time point in the configuration order arrives,, then wait for, after activationary time arrives, then switch in the new configuration and reply, and use the new row communication that is configured into to RNC answer configuration successful if activationary time does not arrive;
114 and 115, RNC confirms UE, and carries out success response to CN;
116, UE and CN carried out the mutual of other after carrying was set up and finished.
For after terminal traffic is set up, follow-up increase business, multi-service circumstances discharge a certain business down, or corresponding service is carried out the situation of DCH-DCH adjustment process, its principle is identical with figure one, the message of air interface can be according to the concrete parameter difference of adjusting, adopt different message, so do not repeat them here.
Yet there is following shortcoming in above-mentioned existing scheme:
1, need activationary time to coordinate RNC and UE uses new link simultaneously, because the complexity of wireless environment, the difference of terminal traffic, not of uniform size the causing of air interface institute message transfer, thus the propagation delay time of idle message is inconsistent, causes the activationary time difficult design;
If the design of 2 activationary time points is excessive, then when wireless environment was better, link configuration can not come into force after finishing, and caused call delay to increase; If the design of activationary time point is too small, when wireless environment was abominable, UE may not receive configuration order owing to disturbing, thereby causes communication disruption;
3, in order to carry out the design of activationary time point, RNC need measure the propagation delay time of UE and network, so as the computing activation time, the expense of increase system;
4, when being configured, need the pre-configured resource of Node B, according to the pre-configured time of computing activation as a result, notify Node B activationary time once more, the reciprocal process more complicated;
5, because the complexity of wireless environment, consider that different business can be inconsistent at the number of times of eating dishes without rice or wine to transmit re-transmission, at computing activation during the time, should be according to maximum retransmission and maximum data packet, come the computing activation time, thereby make that as a rule the time delay that continues that causes calling out increases, and reduces the susceptibility of terminal.
