Description
Technical field
The present invention relates to the 3G (Third Generation) Moblie technical field, particularly relate to the method for service speed regulation under a kind of no cascade operation/no coder operation.
Background technology
At present, Wideband Code Division Multiple Access (WCDMA) inserts (WCDMA) system and provides three kinds of business in circuit switching (CS) territory: adaptive multi-rate coding (AMR) speech business, controlled stream (RCS) business and multi-medium video-signal business.AMR is divided into two types of arrowband AMR (NB-AMR) and wideband A MR (WB-AMR), supports 8 kinds and 9 kinds of voice rates respectively, and the situation of supporting free of data (No Data) and quiet description (SID).3 kinds of data rates of RCS business support.The multi-medium video-signal business belongs to transparent service for radio network controller (RNC), be uncontrollable in its speed of RNC side.For AMR speech business and RCS business,, can carry out speed governing according to the ability of local resource situation and subscriber equipment (UE), to make full use of resource or alleviate congestion in the RNC side.
Under the adjustable situation of speed, the codec among core network (CN) and the UE need receive the signaling of RNC, so that dynamically regulate and use code rate according to the requirement of RNC.Wherein, RNC adjusts downstream data rate by Iu mouth user face (IuUP) to CN transmission rate control messages, adjusts upstream data rate by the chain of command agreement of air interface to UE transmission rate control messages.
When business was in cascade operation/encoderless operation (TFO/TrFO) state, data were through the CN transparent transmission, and CN does not carry out the conversion operations of encoding and decoding to data.Particularly, under the TFO state, though codec physically is present among the CN, codec functions is under an embargo, and this moment, codec was used to finish control or protocol conversion function, and IuUP is used for finishing the exchange of speech data between the codec of RNC and CN; Under the TrFO state, there is not codec among the CN, therefore there be not any conversion or the controlled function relevant with encoding and decoding, IuUP is used to finish the exchange of speech data between calling terminal RNC and the called end RNC.
Under the TFO/TrFO state, because the CN conversion operations that data do not carried out encoding and decoding, on/downstream data rate should be consistent, and that is to say that the downstream rate of an end should be consistent with the upstream rate of an other end.In existing technical scheme, RNC does not carry out active adjustment to upstream rate, when the congested triggering in opposite end or transmitting power trigger need carry out descending speed governing the time, opposite end RNC sends descending speed governing request message to local terminal RNC by IuUP, local terminal RNC adjusts the upstream rate of local terminal according to this speed governing request message.Because data are through the CN transparent transmission, after the upstream rate adjustment of local terminal was finished, the downstream rate of opposite end had also just adjusted automatically.
Fig. 1 is the method flow diagram of service speed regulation under the TFO/TrFO state in the prior art.At first, when business was set up, RNC was in the UE configuration/descending enabled mode collection the corresponding a kind of speed of each pattern that enabled mode is concentrated.Carry out in the process in business, as shown in Figure 1, the method for its speed governing may further comprise the steps:
Step 101: in the time of need carrying out descending speed governing in the opposite end, opposite end RNC sends descending speed governing request message to local terminal RNC, carries the target pattern collection of speed governing in this message.Target pattern collection wherein is the subclass of the descending enabled mode collection in opposite end, is the opposite end RNC resource situation current according to the opposite end, concentrates the set of the target pattern of the speed governing of selecting from descending enabled mode.
Step 102: after local terminal RNC receives descending speed governing request message, judge that the concentrated up enabled mode that whether has pattern to be present in local terminal of target pattern is concentrated, if have, after then from the common factor of target pattern collection and up enabled mode collection, selecting an appropriate mode as speed-regulating mode, execution in step 103; If no, process ends then, speed regulation failure.
Step 103: local terminal RNC sends transport format combination set control (TFC Subset Control) message to local terminal UE, and sends speed governing success response message to opposite end RNC, all carries selectable speed-regulating mode in the message;
Step 104: local terminal UE is adjusted into described speed-regulating mode rate corresponding with code rate after receiving TFC Subset Control message, after opposite end RNC receives speed governing success response message, self correlation behavior position and pattern information is upgraded.
Because the restriction of UE ability, for example restriction of the TFS Transport Format Set of UE (TFS) resource and transport format combination set (TFCS) resource, on the UE/descending enabled mode collection can not all be configured to the set of all patterns that CN supports.Normally descending enabled mode collection is configured to the set of all patterns of CN support, up enabled mode collection is configured to the set of max model, Assured Mode and some middle models of CN support.Like this, on/descending enabled mode collection is not reciprocity, causes in step 102, the target pattern collection of the descending speed governing in opposite end is very possible not in the up enabled mode collection of local terminal, causes the failure of speed governing.
Summary of the invention
In view of this, the present invention proposes the method for service speed regulation under a kind of TFO/TrFO state, under the not reciprocity situation of last/descending enabled mode collection, speed governing still can successfully be carried out.
Method of the present invention may further comprise the steps:
A) in the time of need carrying out descending speed governing in the opposite end, opposite end RNC sends descending speed governing request message to local terminal RNC, carries the target pattern collection of speed governing in this message;
B) local terminal RNC judges that the concentrated up enabled mode that whether has pattern to be present in local terminal of target pattern is concentrated, if do not have, then concentrate and select the adjustable mode collection, and send speed governing negotiate response message, carry the adjustable mode collection in this message to opposite end RNC from the up enabled mode of local terminal;
C) opposite end RNC concentrates from adjustable mode and selects the accepted pattern collection, and sends descending speed governing request message to local terminal RNC, carries the accepted pattern collection in this message;
D) local terminal RNC concentrates from accepted pattern and selects a pattern as speed-regulating mode, sends TFCSubset Control message to local terminal UE, and sends speed governing success response message to opposite end RNC, all carries described speed-regulating mode in the message;
E) after local terminal UE receives TFC Subset Control message, code rate is adjusted into described speed-regulating mode rate corresponding, after opposite end RNC receives speed governing success response message, self correlation behavior position and pattern information is upgraded.
Described business is AMR business or RCS business.
With respect to prior art, the invention has the beneficial effects as follows:
Under the not reciprocity situation of last/descending enabled mode collection, do not need to increase TFS resource and the TFCS resource of UE, by the negotiation of speed-regulating mode between two RNC, guaranteed that the success of speed governing is carried out.

Embodiment
Key of the present invention is: under the TFO/TrFO state, local terminal RNC is when the descending speed governing request message that receives that opposite end RNC sends, if the target pattern of the descending speed governing in opposite end concentrates the up enabled mode that does not have pattern to be present in local terminal to concentrate, then current resource situation according to local terminal, from the concentrated adjustable mode collection of selecting of up enabled mode, and send speed governing negotiate response message to opposite end RNC, carry the adjustable mode collection in this message.Opposite end RNC concentrates selection accepted pattern collection from adjustable mode, and sends descending speed governing request message once more to local terminal RNC when receiving speed governing negotiate response message, carries the accepted pattern collection in this message.Like this, the accepted pattern collection just necessarily is present in the up enabled mode of local terminal to be concentrated, and can guarantee that the success of speed governing is carried out.
Describe the present invention below in conjunction with accompanying drawing.
As shown in Figure 2, among the present invention under the TFO/TrFO state method of service speed regulation may further comprise the steps:
Step 201: in the time of need carrying out descending speed governing in the opposite end, opposite end RNC sends descending speed governing request message to local terminal RNC, carries the target pattern collection of speed governing in this message.
The target pattern collection is the opposite end RNC resource situation current according to the opposite end, concentrates the set of the target pattern of the speed governing of selecting from descending enabled mode.When business was set up, RNC was in the UE configuration/descending enabled mode collection.In the present invention, preferred mode is the set that descending enabled mode collection is configured to all patterns of CN support, up enabled mode collection is configured to the set of max model, Assured Mode and some middle models of CN support.
Step 202: local terminal RNC judges that the concentrated up enabled mode that whether has pattern to be present in local terminal of target pattern is concentrated, if do not have, then concentrate and select the adjustable mode collection, and send speed governing negotiate response message, carry the adjustable mode collection in this message to opposite end RNC from the up enabled mode of local terminal.
If determine that target pattern is concentrated to the up enabled mode that a rare pattern is present in local terminal and concentrates, then the same with prior art, carry out normal speed governing operation.Otherwise the resource situation current according to local terminal concentrated from the up enabled mode of local terminal and to be selected one or more acceptable speed-regulating modes, and with the set of described acceptable speed-regulating mode as the adjustable mode collection.Described speed governing negotiate response message is the 14th quasi-protocol data cell (PDU) of IuUP, and in described PDU, the related bits position is set to the sign that particular value is used as speed governing negotiate response frame.For example, the 2nd and the 3rd of described PDU frame control section (Frame Control Part) can be set to 1 sign that is used as speed governing negotiate response frame.
Step 203: opposite end RNC concentrates from adjustable mode and selects the accepted pattern collection, and sends descending speed governing request message to local terminal RNC, carries the accepted pattern collection in this message.
The accepted pattern collection is the opposite end RNC resource situation current according to the opposite end, concentrates the set of one or more acceptable speed-regulating modes of selecting from adjustable mode.
Step 204: local terminal RNC concentrates from accepted pattern and selects a pattern as speed-regulating mode, send transport format combination set control (TFC Subset Control) and cease this UE, and send speed governing success response message to opposite end RNC, all carry described speed-regulating mode in the message.
In the present invention, concentrate pattern of selection to be preferably from accepted pattern: to concentrate one of selection and the current immediate pattern of row mode that goes up of local terminal as speed-regulating mode from accepted pattern as speed-regulating mode.The purpose of doing like this is in order to guarantee steadily carrying out of speed adjustment process.
Step 205: local terminal UE is adjusted into described speed-regulating mode rate corresponding with code rate after receiving TFC Subset Control message, after opposite end RNC receives speed governing success response message, self correlation behavior position and pattern information is upgraded.
Because the downstream rate of opposite end and the upstream rate of local terminal are reciprocity, after the local terminal upstream rate adjustment success, the downstream rate of opposite end has also just been adjusted successfully automatically.
Method of the present invention goes for various types of business, for example AMR voice service, RCS business.
The invention solves the problem of the service speed regulation failure that causes owing to up-downgoing enabled mode collection is not reciprocity under the present TFO/TrFO state, under the situation of TFS resource that does not increase UE and TFCS resource, the method of utilizing the adjustable mode collection to rewind realizes the negotiation of speed-regulating mode between two RNC, has guaranteed that the success of speed adjustment is carried out.
Should be noted that at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spiritual scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
