Description
Technical field
The present invention relates to mobile communication technology, particularly realize synchronous method, system and equipment between radio network controller (RNC, RadioNetwork Control).
Background technology
As a kind of emerging multimedia service, multi-media broadcasting service (MBMS, MultimediaBroadcast Multicast Service) caused the extensive concern of industry, regarded as the business that application prospect is arranged in the third generation digital communication (3G, 3rd Generation) very much by industry.The MBMS business is meant, mobile phone users receives the digital audio/video frequency content of the forms of broadcasting with the form of channel or channel on the portable terminal with operating system and video capability, as TV programme etc.
Current, for synchronous code division multiple access (TD-SCDMA of time-division, Time Division-SynchronousCode Division Multiple Access) MBMS business in the system such as, adopting multimedia broadcasting single frequency network (MBSFN, Multimedia Broadcast Single Frequency Network) under the condition of networking, belong between each minizone of a RNC, identical frequency, time slot, code channel can have been realized adopting preferably, the MBMS business datum that synchronized transmission is identical.
But, under a lot of situations, also need between the different RNC to carry out synchronously.Such as, for the portable terminal that is in two RNC coverage intersections, it can receive the signal from two RNC simultaneously, if but asynchronous between two RNC, like this, portable terminal receives time of two paths of signals will be inconsistent, one the tunnel is fast, one the road is slow, and that slow road signal is moved terminal possibly as the interference signal processing, thereby influence the normal reception of this road signal.
For addressing the above problem, a kind of MBMS Iur synchronization scenario has been proposed in the prior art, the specific implementation of this scheme comprises following two processes:
1) MBMS Iur data synchronization process:
Fig. 1 is existing MBMS Iur data synchronization process schematic diagram, this process realizes based on network architecture shown in Figure 2, for simplifying accompanying drawing, a target radio network controller (DRNC, Target Radio Network Control) and some critical network entities have only been expressed among Fig. 2.As shown in Figure 1, may further comprise the steps:
Step 101: the RNC in the MBMS service area is configured to service wireless network controller (SRNC, Service Radio Network Control) and DRNC, and SRNC and DRNC are carried out identical physical channel, transmission channel and radio bearer (RB, Radio Bearer) dispose.
Here the service area of being mentioned is meant the professional corresponding coverage of a certain MBMS.Comprise in a certain service area which RNC is that operator can know in advance, so, in this step, operator can be according to self needs, each RNC in the service area is configured to SRNC and DRNC, promptly specifies a RNC as SRNC, other RNC is then as DRNC.Then, further SRNC and each DRNC that is disposed carried out identical physical channel, transmission channel and RB configuration.
Set up the Iur synchronous bearer between step 102:SRNC and each DRNC.
The process of setting up the Iur synchronous bearer in this step is towards disconnected process.As shown in Figure 3, Fig. 3 sets up the process schematic diagram for existing Iur synchronous bearer, wherein:
Step 1021:SRNC sets up request (Sync BearSetup Request) by Iur chain of command message MBMS synchronous bearer, initiates the Iur synchronous bearer and sets up process.
In this step, service center is initiated the MBMS business, and by the Iu interface between core net and the RNC, each RNC in service area comprises that SRNC and DRNC send session and begin (Session Start) signaling.Each DRNC does not do any processing after receiving this Session Start signaling, and after SRNC receives this Session Start signaling, then needs to initiate the Iur synchronous bearer and set up process.
Because SRNC does not also know in self place service area which DRNC is arranged, that is to say, SRNC and do not know in the whole network which RNC with self belong to same service area.So, generally, SRNC can all send MBMS Sync Bear Setup Request message by all RNC in whole network, wherein carries Temporary Mobile Group Identity (TMGI, Temporary Mobile Group Identifier), i.e. information such as MBMS service identification.
Step 1022: the DRNC in the service area is to SRNC feedback MBMS Sync Bear Setup response (Response) message.
After each RNC in the network receives MBMS Sync Bear Setup Request message from SRNC, carry out different processing: the DRNC that is positioned at same service area for those and SRNC, owing to pass through the pre-configured of operator, know that the RNC that sends this message is SRNC, and received Session Start instruction in advance, so, these DRNC will distribute local synchronous bearer resource, set up the Iur synchronous bearer, and to SRNC feedback MBMS Sync Bear Setup Response message; And for the RNC that those and SRNC are positioned at the different business zone, then the MBMS Sync Bear SetupRequest message that receives is not handled.
Step 103:SRNC handles the MBMS business datum that is received from core net, and the Iur synchronous bearer that passes through to be set up is sent to each DRNC.
In this step, core net sends the MBMS business datum by Iu interface all RNC in service area, each DRNC does not handle the MBMS business datum that receives, and after SRNC receives the MBMS business datum, then need to carry out Iu interface user plane (IuUP, Iu User Plane), user plane (the GTP-U of general packet wireless service tunnel protocol, General Packet Radio ServiceTunneling Protocol-User Plane), PDCP (PDCP, Packet DataConvergence Protocol) and Radio Link control (RLC, Radio Link Control) waits the processing of each layer protocol, pass through the Iur synchronous bearer set up then, send Iur Frame Protocol (FP, Frame Protocol) frame to each DRNC.Carry in each Iur FP frame: a Transmission Time Interval (TTI, Transmission Time Interval) the rlc protocol data cell (PDU that sends in, Protocol DataUnit) number, RLC PDU data and the information such as timestamp of eating dishes without rice or wine to send the Connection Frame Number zero hour (CFN, Connect Frame Number) of indicating these RLC PDU data.
Step 104: the MBMS business datum after the processing that each DRNC will receive sends to the MAC layer at multi-media broadcasting service (MAC_m) entity in local each sub-district.
MAC_m entity in each sub-district determines that according to the timestamp information that carries in the Iur FP frame the initial CFN of TTI that sends the RLC PDU data of carrying in the IurFP frame also sends constantly.
The above-mentioned process that is existing MBMS Iur data sync.By said process, belong between the RNC in the service area and shared same Iu data flow, and shared entities such as same PDCP and RLC, thereby from having avoided each RNC to handle inconsistent that the MBMS business datum is caused respectively in essence.In logic, SRNC has regarded the sub-district of each DRNC as local sub-district, has realized that by the Iur interface RLC entity continues to the data flow of MAC_m entity.
Need to prove that in MBMS business datum transport process or after transmit finishing, among SRNC and the DRNC either party all can initiate MBMS Iur synchronous bearer dispose procedure, as shown in Figure 4, Fig. 4 is existing MBMS Iur synchronous bearer dispose procedure schematic diagram.RNC1/RNC2 among Fig. 4 can be respectively SRNC/DRNC or DRNC/SRNC.That is to say, after core net sends conversation end (Session Stop) message by Iu interface all RNC in service area, SRNC or DRNC all can send the MBMS synchronous bearer to the other side and discharge (Sync Bear Release) message, discharge the Iur synchronous bearer of being set up.But the MBMS Sync Bear Release message that SRNC sends is to set up the DRNC of carrying with it at all, and the MBMS Sync Bear Release message that DRNC sends is then just at the carrying of setting up between self and the SRNC.Receive that the RNC of MBMS Sync Bear Release message will discharge the local synchronous bearer resource of self.Need to prove that DRNC also can be because other reason is initiated Iur synchronous bearer dispose procedure, such as, itself breaks down DRNC, can not carry out normal data processing etc., and specific implementation repeats no more.
2) MBMS Iur time synchronization process:
In this programme, SRNC need calculate the timestamp of eating dishes without rice or wine to send the CFN zero hour of each RLC PDU, and stab computing time, needs then to consider that data send to the propagation delay time of DRNC from SRNC.In this programme, can obtain propagation delay time by following dual mode:
A, configuration be the maximum transmitted time delay fixedly: such as, linkage length between SRNC and each DRNC is in advance as can be known, so, can estimate propagation delay time between SRNC and each DRNC according to linkage length, and with the maximum transmitted time delay that estimates as fixing maximum transmitted time delay.Afterwards, SRNC calculates the timestamp of each RLC PDU according to being somebody's turn to do fixedly maximum transmitted time delay.
B, obtain synchronously by RNC Iur node: it is synchronous that SRNC and each DRNC carry out node respectively, and obtaining the propagation delay time of each DRNC, and the maximum of getting wherein stab computing time.Such as, SRNC sends test post to each DRNC, calculates this test post and comes and goes required time, thereby obtain one way transmission required time, and this time is propagation delay time.
Comprehensive above-mentioned introduction as can be seen, though existing MBMS Iur synchronization scenario can realize between the different RNCs synchronously, but, in existing MBMS Iur synchronization scenario, belong to each RNC in the same service area and can not know RNC aggregate information in this service area, promptly remove self which RNC in addition in the service area.So, when SRNC initiation Iur synchronous bearer is set up process, do not know specifically need send MBMS Sync Bear Setup Request message, can only all send this message by all RNC in network, to wait for the response of each RNC to which DRNC.
And it is as well known to those skilled in the art, SRNC is before sending MBMS Sync Bear SetupRequest message to RNC, at first need and RNC between set up communication link, utilize the communication link set up could send this MBMS Sync Bear Setup Request message then; And belong to the less part that RNC quantity in a certain service area only accounts for all RNC quantity in the whole network usually, that is to say that in the communication link that SRNC set up, major part all is useless, thereby caused the serious waste of link circuit resource.
