Compared with prior art, the technical scheme that the embodiment of the present invention proposes has the following advantages:
By applying the technical scheme of the embodiment of the present invention, MCE is by M2 interface, the information of MBMS priority is sent to base station, to make base station can according to the information of this MBMS priority, determine the unicast service of respective cell and the priority relationship of MBMS, thus, base station can be made to know the information of the MBMS priority that network upper level node configures, when the reception of MBMS and unicast service clashes, more reasonably judge retain which kind of business, avoid network side congested further, and ensure that Consumer's Experience.
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention proposes is described.
The present invention proposes a kind of processing method of MBMS priority, basic major technique thought is: the precedence information that MBMS is relevant is supplied to eNB by network controls node, when the community at MBMS place occurs congested, eNB utilizes this precedence information to carry out two priority classes and management to the clean culture of UE and MBMS.
In concrete process scene, following two kinds of concrete processing modes can be comprised.
Mode one:
MCE passes through the signaling procedure of the MBMS relevant (MBMS-Service-associated) of M2 interface by priority (the Allocation and Retention Priority of each MBMS, ARP, distribute and keep priority) message notice give corresponding eNB.
In practical application, the signaling of carrying this priority can be: MBMS Session Start Request, MBMS Session Update Request etc.
Mode two:
The overall precedence information of MBMS can be informed to corresponding eNB by the signaling procedure of the MBMS of M2 interface irrelevant (non MBMS-Service-associated) by MCE.
In practical application, the signaling of carrying this priority can be: MBMS Scheduling Information, MBMS Service Counting Request, M2 Setup Response, MCE Configuration Update, an eNB Configuration Update Acknowledge or independent one new signaling.
It should be noted that, the combination in any of following form can be comprised herein about the information of MBMS priority:
QCI(QoS Class Identifier, service quality rating identifies, QoS, Quality of Service, service quality) information;
GBR (Guaranteed Bit Rate keeps bit rate) information;
ARP information;
The precedence information of new definition.
The judgement MBMS that following examples relate to and the method for clean culture priority, go for the judgement when the connected state user receiving MBMS expects when switching to a congested MBMS community, also may be used in the scene that other similar MBMS and clean culture can not maintain simultaneously.
Embodiment one
The aforesaid mode one of corresponding employing, the application scenarios of the precedence information of each MBMS of notice eNB.
(1) processing procedure of MCE side.
In existing MBMS related framework, the priority of each MBMS session and quality of service relevant information are notified MCE node by the MBMS controlled entity of core net.
Next, suitable precedence information and/or operation quality requirement information, when sending MBMS Session Start Request message to eNB by M2 interface, carry, send to eNB by MCE node.
Or, when the priority that MBMS is correlated with and/or service quality information change, by MBMS Session Update Request message, the service priority after renewal and/or operation quality requirement information are carried, send to eNB.
(2) processing procedure of eNB side.
ENB receives MBMS Session Start Request or MBMS Session Update Request message from MCE, therefrom obtains the relevant priority of this MBMS and/or service quality information, stores this information.
When occurring congested due to community, MBMS place, when the unicast service of certain UE and MBMS cannot maintain simultaneously, the priority of the unicast service that eNB receives according to this UE and operation quality requirement information, to receive with this UE or the priority of interested MBMS and/or operation quality requirement information compare, if the priority of clean culture is high, then eNB is by the community of the unicast handover of UE to other non-MBMS, to ensure the normal reception of UE unicast service, now the MBMS of UE possibly cannot continue to receive; If the priority of MBMS is high, then the unicast service of UE discharges by eNB, or only leaves the business not needing speed to ensure, makes UE still can receive MBMS from this MBMS community.
As eNB because the problem of MBMS small area jam, judge UE to be switched to the service that clean culture is continued in other community according to priority, and give up in the situation of MBMS reception, if follow-up eNB finds that MBMS small area jam has been alleviated or alleviated, then can according to the list information interested etc. of algorithm and UE, if this UE is still interested in the business of this MBMS frequency, then the user being switched to other community before initiatively can be switched to this MBMS frequency by eNB again, provides clean culture and MBMS to continue as user simultaneously.
It is further noted that, when MBMS priority and unicast service priority are compared, likely because these priority are sequences of independent definition separately, such as clean culture priority 1 level and MBMS priority 1 level are likely not reciprocity, the algorithm of eNB is now needed to carry out certain conversion process or by OAM/ core net node, the corresponding relation of priority informed to eNB, then eNB carries out priority judgement again, or core net upper level node notes the mapping of sequence when arranging clean culture and MBMS priority, and by mapping relations by signalling format or OAM collocation form notice eNB, be beneficial to eNB and carry out priority ratio between clean culture and MBMS comparatively.This situation also may occur in the examples below that, and processing method is consistent.
