Description
Technical field
The present invention relates to the communications field, relate in particular to the cell broadcast service optimization method in a kind of WCDMA system.
Background technology
In the WCDMA system, multicast and broadcasting are the modes that transmits data from a data source to a plurality of targets, in traditional mobile network, cell broadcaste service (CBS, cell broadcast service) allow low bit rate data to share broadcast channel by the sub-district and send to all users, this is a message based business.
People no longer are satisfied with phone and messaging service to the demand of mobile communication now, fast development along with the Internet, a large amount of multimedia services emerge, in some applied business, a plurality of users can receive identical data simultaneously, and are numerous as video request program, television broadcasting, video conference, online education, interactive game or the like.These mobile multi-media services are compared with general data, and characteristics such as data volume is big, longer duration, delay sensitive are arranged.Present procotol (IP) multicasting technology is not suitable for the mobile network, because the mobile network has particular network structure, functional entity and unique wave point carrying, these are all different with wired IP network, so existing IP multicasting technology can not make a plurality of mobile subscribers share mobile network resource.
For realizing utilizing most effectively mobile network resource, Wideband Code Division Multiple Access (WCDMA)/Global Systems for Mobile communications (WCDMA/GSM) global standardsization organize third generation partner program (3GPP) to propose multimedia broadcast/multicast service (MBMS, Multimedia Broadcast/Multicast Service).MBMS refers to that a data source sends the point-to-multipoint service of data to a plurality of users, realizes that Internet resources share, and comprises that mobile core network and access network resource share, especially interface-free resources.The MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can realize the multimedia service multicast and the broadcasting of two-forty, and this has complied with the trend of following mobile data development undoubtedly.
In the UMTS system configuration, can realize cell broadcast service (CBS) business, can finish Word message periodically by common signal channel broadcast transmission in cell range.For realizing above-mentioned functions, according to the 3GPP agreement, broadcasting and multicast center (BMC) are realized in each sub-district, finish the storage to broadcast, according to the different repetition period timer-triggered schedulers of each broadcast setting and finish the transmission of message.From the angle of operation, wish that every sub-district can provide possibility many broadcasts; On the other hand, the bandwidth constraints of respective channels, too much broadcast can cause the congested of channel, can not in time issue.Therefore, finish the real-time detection function to cell broadcaste service, can understand the actual broadcast business model, the service guidance operation is the important indicator of network performance.
Agreement 3GPP TS 32.403 has described method and the principle that network side carries out Performance Detection.For RNC,, divide into RRC process, RAB process, signaling and connect between foundation, soft switching process, direct-cut operation, transition process, system handoff procedure etc. basically from the angle of flow process.Each equipment vendors is according to this agreement, for operator provides unified Performance Detection function service.Detection method is divided into accumulative total and detects (CC), dynamic variable detection (GAUGE), discontinuous event registration (DER), status checkout (SI).Detected object is divided into based on RNC with based on the detection of sub-district.
Cell broadcast service (CBS) relates to the realization of RAN side, by present detection, operator can't obtain the data that current network provides cell broadcast service from Performance Detection, also just can't intuitively understand the situation of current area broadcast service all sidedly, therefore the present invention proposes more perfect cell broadcast service (CBS) Performance Detection index, according to the result who detects, can relatively get information about the ruuning situation of the relevant cell broadcast service of network (CBS) up till now, as: the traffic load situation, channel width takies situation etc.
For the operator that cell broadcast service is provided, realize service application effectively, will inevitably need the applicable cases and the detection data of business are done comprehensively to analyze.Therefore provide the cell broadcaste service Performance Detection, will carry out this service and decision-making to operator provides very big facility, and also the practical application for cell broadcast service provides abundant data.Result according to detecting can relatively get information about the ruuning situation of the relevant cell broadcast service of network (CBS) up till now.
Summary of the invention
