Description
Technical field
The reception situation letter of user equipment is obtained the present invention relates to mobile multimedia communication field, more particularly to a kind of network element
The method and system of breath.
Background technology
With the fast development of Internet and the rapid popularization of the multi-functional mobile terminal of giant-screen, a large amount of shiftings are occurred in that
It is dynamic data multimedia and various high bandwidth multimedia services, such as video conference, television broadcasting, video request program, advertisement, online
Education, interactive game etc., on the one hand meet mobile subscriber to multiple services demand, while also for mobile operator brings newly
Business growth point.These mobile data multimedia service requirements multiple users can simultaneously receive identical data, and general
Data service is compared, with data volume it is big, the duration is long, delay sensitive the features such as.
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd
GenerationPartnership Project) propose multimedia broadcast multi-broadcasting business (MBMS, Multimedia
BroadcastMulticast Service), MBMS is that one kind transmits data from a data source to multiple destination mobile terminals
Technology, realize the shared of Internet resources (including core net and access network), improve Internet resources (especially air interface
Resource) utilization rate.The MBMS of 3GPP definition can not only realize the broadcast of message class and the multicast of plain text low rate, but also
Broadcast and the multicast of high-speed multimedia service can be realized, there is provided various abundant videos, audio and multimedia service, this is undoubtedly
The trend of following mobile data development is complied with, for the development of 3G provides better services prospect.
At present, MBMS technologies are introduced in the LTE of R9 versions, and it is strengthened in R10 version.In LTE
MBMS chain of command and user plane separate, chain of command transmit MBMS control signaling, user plane transmit MBMS data.Specifically
, abbreviation base station behind evolved base station (eNB, evolved Node B), by BCCH (BCCH, Broadcast
Control Channel) control information of MBMS is sent to user equipment (UE, User Equipment), UE according to from
The control information of the MBMS received on BCCH is in the control channel (MCCH, Multicast ControlChannel) of MBMS
The configuration information of MBMS is received, then according to the configuration information of the MBMS on MCCH, UE can be from the Traffic Channel of MBMS
The MBMS that base station sends is read on (MTCH, Multicast Traffic Channel).MCCH and MTCH are finally multiplexed into multicast
Point-to-multipoint (PTM, Point-to-Multipoint) transmission is carried out on channel (MCH, MulticastChannel).Wherein,
Minimum 80ms dispatching cycle of MCH, and with MBMS SFNs (MBSFN, MBMS Single FrequencyNetwork)
The mode of frame is transmitted.
The UE or terminal for receiving MBMS may be at two states, a kind of state be radio resource control (RRC,
Radio Resource Control) connected state (referred to as connected state), another kind is RRC Idle state (referred to as Idle state).
Whether unicast service is received according to UE or terminal, it can be determined that the UE for receiving MBMS is in connected state
Idle state.When UE is when unicast service is received, UE is in connected state, and the UE in Idle state does not set up RRC companies with network side
Connect, the UE in connected state then establishes RRC and is connected with network side.When UE is in connected state, base station will measure for UE is configured
Interval (measurement gap), the measurement interval length is 6ms, and the cycle is 80ms.
When the UE in connected state receives MBMS, base station may be simultaneously its configuration measurement interval, so, then base
Stand send MBSFN sub-frame will likely with for the measurement interval that UE is configured conflicts, Fig. 1 be in the prior art measurement interval with
The distribution schematic diagram of MBSFN sub-frame, as shown in figure 1, radio frames 2 and radio frames 4 are MBSFN radio frames, wherein, in radio frames #2
In, comprising 0 to 9 totally 10 subframes, subframe 1, subframe 3, subframe 5 and subframe 6 are to send the MBSFN sub-frame of MBMS.Now,
Because base station is not aware that whether the UE receives MBMS, therefore during configuration measurement interval, measurement interval may be configured to
Send in the radio frames of MBMS.For example, base station is by subframe 0 to subframe 5, and totally 6 subframes are configured to the measurement interval of the UE, then should
UE cannot receive in subframe 1, subframe 3 and subframe 5 MBMS (here give tacit consent to measurement interval priority higher than MBMS reception,
Because base station will first ensure that unicast service is not affected).Therefore, base station must understand the reception situation of the MBMS of the UE, really
The reception in view of UE to MBMS when measurement interval is configured is protected, both conflicts are avoided as far as possible.
Additionally, the switching of the UE in connected state is controlled by base station.Current switching principle is：Base station control UE is surveyed
Amount, then the measurement result according to UE considers the signal quality and business load situation of neighbor cell, and UE is switched into conjunction
Suitable cell.But, for the UE for receiving MBMS, base station is not aware that reception situations of the UE to MBMS.Therefore, base station
For the cell of UE selections possibly cannot provide the MBMS that the UE is being received.The small of MBMS can not be provided when UE is switched to by base station
Qu Hou, UE can not continue to the MBMS.So as to the continuity that UE receives MBMS cannot ensure that the Consumer's Experience of UE will also be received
To strong influence.
Therefore, problems with present in the research of prior art and practice process：First, base station does not know that UE is current
The reception situation of MBMS, measurement interval configuration may be sent in the subframe of MBMS, and causing UE to receive should
MBMS is interrupted；When second, UE use the cell switching flow selection target cell of unicast, base station does not know the current MBMS's of UE
Reception situation, it is impossible to ensure that the UE for receiving MBMS is preferentially switched to the cell for sending the business so that UE is received
The continuity of MBMS cannot ensure well.For the two problems, it is necessary to find such a method：Base station can be as early as possible
The MBMS for knowing that UE is current reception condition information, so as to for the UE configuration measurement interval and determination Target cell when, energy
In view of the MBMS that UE is currently being received, continuous receptions of the UE to MBMS is ensured as far as possible, with improve MBMS continuity and
The Consumer's Experience of UE.
