Description
Technical field
The present invention relates to simultaneous techniques, espespecially a kind of method and system realizing Common Control Channel message synchronization.
Background technology
Multimedia broadcast-multicast service (MBMS, Multimedia Broadcast Multicast Service) technology is a data source sends point-to-multipoint service from data to multiple user, (comprise mobile core network and access network resource to share to realize network resources locating, especially interface-free resources), make use of mobile network resource most effectively.
As a kind of technology improving the MBMS availability of frequency spectrum, MBMS single frequency network (MBSFN, MBMS Single Frequency Network) wireless signal that technical requirement adjacent base station synchronized transmission is identical, subscriber equipment (UE, User Equipment) signal coming from different base station can be considered as multipath signal, make the receiving gain that MBMS signal acquisition is larger, thus improve service quality (QoS, the Quality of Service) performance of MBMS.
To multicast control channel (MCCH) message of MBMS, also exist with the demand of MBSFN mode synchronized transmission.According to the regulation of 3GPP existing protocol, MCCH is logic channel, and MCCH message comprises a series of MBMS control message.Specifically, MCCH message comprises the configuration information of MBMS, such as the configuration information etc. of physical channel, transmission channel, logic channel; Also may comprise the configuration information that non-traffic is relevant, the such as configuration information of MBMS notification channel, the general information etc. of MBMS.If need to send multiple MBMS a community to be engaged in, so, the configuration information of above-mentioned each business in MCCH message, should be comprised.
In existing Long Term Evolution (LTE) technology, MCCH message bearing is in MCCH channel, MCCH channel is logic channel, be carried on multicast transmission channel (MCH), and MCH channel is finally mapped on multicast physical channel (PMCH).PMCH channel adopts MBSFN mode to send, and this just means that MCCH message also should send to UE in MBSFN mode, and therefore, MCCH message content needs in MBSFN region, keep synchronous.
MCCH message is when wave point transmits, adopt wireless heterogeneous networks (RRC, Radio ResourceControl) protocol code, RRC is encoded to ASN.1 coded format, and described RRC coding is alternatively the ASN.1 coding of RRC protocol message or cell.Along with the development of technology, same RRC information is also constantly developing and is introducing new content, and constitute different RRC versions, the RRC information between different RRC versions has different message formats and content.In the protocol infrastructure of existing 3GPP, RRC coding adopts forward compatibility technology, that is, the RRC of later release encodes the RRC coding of compatible lowest version, like this, when the UE of different editions receives the RRC coded message of highest version, the RRC coded portion that its version is corresponding can be solved, and can not solve the new function that follow-up highest version is introduced.Adopt RRC version to encode to RRC information, refer to and adopt the RRC information form that described RRC version is corresponding to build RRC information, and carry out ASN.1 coding.
In the method realizing MCCH channel synchronization at present, wherein one is:
Multiple cell multicast coordination entity (MCE, Multi-cell/multicast Coordination Entity) network element is by the more fresh content of chain of command message instruction base station (eNB) network element relevant MCCH message, after eNB receives chain of command message, the MCCH message upgrading home cell independently, carry out MCCH message Radio interface protocols RRC coding.And by agreement predefine rule, ensure that the coding result of different e NB is consistent, such as to the content of the list in MCCH message, predefine rule arranges according to the ascending order of list content or descending, avoid different e NB differently to arrange the content of described list, cause the inconsistent of coding result between each eNB.
In the method for this more fresh content by the relevant MCCH message of MCE network element instruction eNB network element, the RRC version can supported due to different eNB may be different, exist MCCH that different eNB indicates according to identical MCE more fresh content to carry out the result of RRC coding different, thus the successful realization of MCCH channel synchronization can not be guaranteed.
Realize in the method for MCCH message synchronization at another kind, MCE network element completes the RRC coding of MCCH message, again the MCCH message after coding is sent to eNB network element, eNB sends the MCCH message of MCE coding at wave point, simultaneously, eNB carries out RRC decoding to described MCCH message, to read the more fresh content of MCCH message, and carries out wireless interface resource configuration according to this.For this method, if the RRC version that different e NB can support is different, and MCE is when MCCH message carries out RRC coding, have employed the RRC version that some eNB can not support, will inevitably occur that these eNB by MCCH message of correctly intactly decoding, thus correctly can not can not carry out the resource distribution renewal of wave point according to the instruction of MCCH message.
Mention the method realizing MCCH channel synchronization above not only to may be used for, in LTE framework, UTRAN framework can being applied to equally, in UTRAN HSAP+ framework.In UTRAN framework, master network controller (MRNC) and net control controller (CRNC), the functional role of MCE and eNB respectively in corresponding LTE.In UTRAN HSAP+ framework, dominant base node (Master NodeB+) and from base-station node (Slave NodeB+), the functional role of MCE and eNB respectively in corresponding LTE.Wherein, MCE, MRNC and Master NodeB+ network element can be collectively referred to as center network element; ENB, CRNC and Slave NodeB+ can be collectively referred to as distribution network element.Fig. 1 is the network architecture diagram comprising center network element and distribution network element, as shown in Figure 1, center network element and one or more distribution network element are set up connection, for coordinating the synchronous distribution MBSFN resource of multiple distribution network element and realizing MCCH message or system message, or the Common Control Channel message that needs MBSFN mode to send such as other Common Control Channel message is synchronous.
