Description
Technical field
The present invention relates to the digital mobile communication technical field, relate in particular to a kind of voice and video user rate negotiation method and system.
Background technology
IP Multimedia System (IP Multimedia Subsystem, IMS) be the 3G network core technology standard that third generation partner program (3GPP) is organized to set up at first, at present by International Telecommunications Union's telecommunication standards group (ITU-T) and the European Telecommunication Standard committee (ETSI) approval, include next generation network (Next Generation Network in, NGN) core standard framework, and be considered to realize not fixing/mobile network merges (Fixed-mobile convergence, important technology basis FMC).
IMS has proposed the network architecture of all-IP, and (Session InitiationProtocol SIP) controls, and realizes mobile management, Multimedia session signaling and bearer services transmission, realizes IP operation end to end to adopt conversation initialized protocol.
IMS is a core key-course, the Access Network that inserts the IMS net is IP universal access network (IP-Connectivity Access Network, IP-CAN), be that Access Network can be any IP network, such as LTE net, WCDMA net, CDMA2000 net, WLAN or ADSL, Cable can be linked into the IMS territory.The core control aspect that IMS provides is irrelevant with access, realization FMC that so just can be real.
Traditional telephone network is with the circuit exchange mode transferring voice, and the transmission bandwidth of requirement is 64kbit/s.The networking telephone (Voice over Internet Protocol, VoIP) be to be transmission platform with the IP packet switching network, by the IP network transferring voice, its basic principle is by voice compression algorithm speech data to be carried out compressed encoding to handle, then the speech data behind these compressed encodings is packed according to agreements such as IP, through IP network packet is sent to reception ground, again these VoPs is reverted to original voice signal through decoding decompression processing.Handle through compressed encoding, under identical bandwidth condition, can increase the calling number of support greatly.
At present, (Long-Term Evolution, LTE) in the system, the VoIP business realizes that by IMS its call establishment as shown in Figure 1 to Long Term Evolution.Calling subscriber A is after called subscriber B makes a call, whole call establishment divides following several steps, callee side evolution base station (eNB), Mobility Management Entity (Mobility Management Entity have been simplified among the figure, MME), gateway (Serving Gateway, S-GW), strategy and charging rule functions (Policy and Charging Rules Function, PCRF), agent conversation control function (Proxy Call Session Control Function, entity such as PCSCF), replace with ellipsis, other accompanying drawing and this figure are similar among the present invention:
Step 101: (E-UTRAN NodeB, (Radio Resource Control RRC) connects eNB) to set up Radio Resource control by Signalling exchange for user (UE) A and this side group station.
Step 102: (Packet Data Network Gateway PDN-GW/P-GW) sets up IP-CAN with PCRF to the grouped data network gateway of user A side.
Step 103: user A and this side eNB and MME set up default radio bearer by Signalling exchange (Radio Bearer RB), are used for the carrying of SIP.
Step 104: two end subscribers carry out coding/decoding negotiation by the SIP Signalling exchange through (two ends) PCSCF, and the result of negotiation comprises user rate, and user rate comprises uplink and downlink, promptly be two-way, and uplink and downlink is consistent.Here up refers to the user to the wireless network direction, the descending direction that refers to wireless network to the user, down with.
Step 105: user A notifies negotiation result the MME of this side by this side PCSCF, PCRF, GW (P-GW or P-GW and S-GW).
Step 106: the MME of user A side notifies user A the eNB of side according to negotiation result, and this eNB notifies user A and sets up professional radio bearer.
In the above-mentioned steps 104, two end subscribers carry out the process of coding/decoding negotiation and see shown in Figure 2.Among the figure, the complete encoding and decoding S set DP1 that UE1 structure UE1 supports sends to PCSCF1 by INVITE, if PCSCF1 receives the INVITE (SDP1) of UE1, check and find that SDP1 does not satisfy the strategy that operator is provided with at PCSCF1, can be to UE1 feedback Reason For Denial, UE1 initiates the coding/decoding negotiation request again according to this reason.In like manner, SCSCF1 or SCSCF2 or PCSCF2 refusal can allow UE1 initiate the coding/decoding negotiation request again.In addition, whether PCSCF1 consults with PCRF1 in this process, and by the strategy decision of operator, same, whether PCSCF2 consults with PCRF2, also is by the strategy decision of operator.
Find out that thus in this call establishment, the wireless network load is not considered in the negotiation of user rate, like this, operator just can't load according to wireless network and adjust voice user's speed.At present, wireless network load has only eNB to know, so eNB is to user rate, such as guarantee speed (GuaranteedBit Rate, GBR)/(Maximum Bit Rate MBR) should have right to speak to maximum rate.
More common situation is, in call establishment, when the wireless network duty ratio is bigger, operator is when considering business experience, user's requesting users speed can be reduced certain amplitude,, reduce call loss so that can insert more user, after treating that the wireless network load alleviates, recover the speed that the user needs again.
Summary of the invention

Embodiment
Core concept of the present invention is: in call establishment, and the negotiations process of eNB participating user speed, for example negotiations process of GBR/MBR, the while does not influence the duration of call setup.The embodiment of this paper is that example describes with AMR-NB (Adaptive Multi-Rate Narrowband).
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
The present invention proposes two kinds of improved procedures to existing procedure, first improved procedure as shown in Figure 3, concrete steps are as follows:
Step 301: calling subscriber A sets up RRC with this side eNB by Signalling exchange and is connected;
Step 302: the PDN-GW and the PCRF of user A side set up IP-CAN;
Step 303: eNB of calling subscriber A and this side and MME set up default radio bearer (RB) by Signalling exchange, are used for the carrying of SIP;
Step 304: through the PCSCF at two ends, carry out coding/decoding negotiation by the SIP Signalling exchange between calling subscriber A and the called subscriber B, the result of negotiation comprises initial user speed;
Among the present invention, user rate comprises up user rate and downlink user speed, can unify as required to be configured, and also can be configured respectively, and promptly upstream and downstream user speed can be different;
Step 305: calling subscriber A notifies this side MME by this side PCSCF, PCRF, gateway GW (P-GW or P-GW and S-GW) respectively with negotiation result, comprises initial user speed in the negotiation result; The notification procedure of called subscriber B side is omitted among the figure with this step.
Step 306: the MME of calling subscriber A side gives negotiation result the eNB of calling subscriber A side by E-RAB (E-UTRAN RadioAccess Bearer) message informing;
Step 307: the eNB of calling subscriber A side according to current wireless network load situation in conjunction with transmission quality requirements, the user rate that makes new advances of decision-making;
Decision methods is: if the current network load is heavier, adopt initial user rate can cause network load to increase the weight of or other reduction of property indexes, then the base station selects the user rate of the low one-level of speed as new user rate according to user rate collection and selection strategy that the user supported from the user rate collection that the user supported; If the current network load is lighter, adopt initial user rate can not cause network load to increase the weight of or other performance loss, then initial user rate is still selected to use in the base station, does not make at user rate under the situation of change, can handle according to the handling process of prior art.
Step 308: after new user rate is used in the eNB decision-making of calling subscriber A side, set up RRC with calling subscriber A according to new user rate and be connected;
Step 309: the eNB of calling subscriber A side carries new user rate in giving the feedback of MME;
Step 310: the MME of calling subscriber A side notifies new user rate to end subscriber by GW, PCRF, PCSCF;
Step 311: called subscriber B initiates new coding/decoding negotiation based on new user rate.
Called subscriber B if find that its speed is different with initial user speed, then initiates new coding/decoding negotiation after knowing new user rate; Preferably, if new user rate is lower than initial user speed and local terminal support, then can initiate new coding/decoding negotiation.
The present invention propose to second kind of improved procedure of existing procedure as shown in Figure 4, concrete steps are as follows:
Step 401-step 409: with the step 301-step 309 of first kind of improved procedure;
Step 410: the MME of calling subscriber A side is with the GW notice PCRF of new user rate by this side;
Step 411: initiate new coding/decoding negotiation based on new user rate by calling subscriber A.
Calling subscriber A if find that its speed is different with initial user speed, then initiates new coding/decoding negotiation after knowing new user rate; Preferably, if new user rate is lower than initial user speed and two ends are all supported, then can initiate new coding/decoding negotiation.
So second kind of improved procedure initiated new coding/decoding negotiation with the different of first kind of improved procedure by the calling subscriber.
Based on above-mentioned first kind and second kind of improved procedure, behind call setup, if eNB detects the current wireless network load and changes, eNB can on-the-fly modify up and/or descending user rate, eNB at first notifies local terminal user uplink and/or downlink user speed, and be revised as new user rate, then new user rate is notified to MME, MME is notified to new user rate to end subscriber or PCRF by GW, and end subscriber or this end subscriber are according to circumstances determined whether initiate new coding/decoding negotiation.
In the preferred embodiment of the present invention, network load value and user rate are negative correlation, eNB can all be divided into n interval with network load and user rate, the value in i network load interval is greater than the value in i+1 network load interval, the value in i user rate interval is less than the value in i+1 user rate interval, described 1≤i≤n; If the current network load is positioned at i interval, for each user rate that user rate is concentrated, eNB determines the residing interval j of this user rate, if j≤i then the current network load support this user rate, otherwise do not support that eNB can come to determine to adjust the size of speed in view of the above.
In the preferred embodiment of the present invention, MME is sent to GW by " user rate notification message " with new user rate; GW is sent to PCRF by " CC-Request message ", " Re-Auth-Answer re-authenticates response message " or " user rate notification message " with new user rate; PCRF is by " DiameterAA-Answer message ", and " Re-Auth-Request message " or " user rate notification message " is sent to PCSCF with new user rate; PCSCF is sent to UE by INFO, INVITE, MESSAGE, NOTIFY, UPDATE message or the user rate notification message of SIP with new user rate.
In the preferred embodiment of the present invention, the user rate that calling is carried out in the process is consulted also can adopt method of the present invention, after finding that as eNB the wireless network load changes, need to adjust user rate, then according to current uplink and downlink user rate a new uplink and downlink user rate is proposed by eNB, the same call establishment of subsequent process, be that eNB notice local terminal UE adopts new user rate, notify MME this new user rate simultaneously, initiate new rate consulation process by this end subscriber again, perhaps notify end subscriber by end subscriber is initiated new rate consulation process by GW by MME.
The present invention proposes is used to realize that the system of voice and video user rate machinery of consultation divides from functional module, can be divided into following several module:
Initial user rate consulation module, this module are used for carrying out coding/decoding negotiation between calling subscriber and the called subscriber after calling subscriber and network side are set up radio bearer, thereby determine initial user speed;
