Description

Method and device for processing MBMS (multimedia broadcast multicast service) statistical message

Technical Field

The present invention relates to the field of Multimedia Broadcast Multicast Service (MBMS), and in particular, to a method and an apparatus for processing MBMS statistics information.

Background

With the rapid development of the internet and the popularization of large-screen multifunctional mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services have appeared, such as: video conference, television broadcasting, video on demand, video advertisement, online education, interactive games and the like, which not only meet the ever-rising service demands of mobile users, but also bring new service growth points for mobile operators. These mobile data multimedia services require that multiple users can receive the same data at the same time, and compared with general data services, have the characteristics of large data volume, long duration, time delay sensitivity, and the like. In order to effectively utilize mobile network resources, the third Generation Partnership Project (3 GPP) proposes a Multimedia Broadcast Multicast Service (MBMS), which is a technology for transmitting data from a data source to a plurality of destinations, enables sharing of network (including core network and access network) resources, and improves utilization of network resources (especially air interface resources). The MBMS service defined by 3GPP can not only implement pure text low-rate message multicast and broadcast, but also implement broadcast and multicast of high-speed multimedia service, and can provide various rich video, audio and multimedia services, which undoubtedly follows the development trend of future mobile data, and provides better service prospects for the development of third Generation digital communication (3G, 3rd Generation).

The MBMS service is transmitted in a multimedia broadcast multicast service Single Frequency Network (MBSFN) mode, where the MBSFN mode is a multi-cell joint transmission mode, that is, cells in a certain geographical location all transmit the same MBMS service data on the same time and Frequency resources, and the certain geographical location is referred to as an MBSFN area. Therefore, in the whole MBSFN area, the radio wave signals corresponding to the data transmitted from each cell are naturally superposed, so that the signal intensity is greatly improved.

In practical applications, a network side needs to know a receiving condition of a certain MBMS service in an MBSFN area, that is, knows how many User Equipments (UEs) of the MBMS service are receiving, or how many UEs are interested in the MBMS service to be transmitted. Because the network side can close the transmission of the MBMS when the network side knows that the UE does not receive a certain MBMS due to no user interest, the network side can save time-frequency resources and electric energy.

However, for the above requirements, how the network side should send the statistical message for requesting the relevant UE to perform feedback for the MBMS service, and how the feedback of the UE should be detected and processed, corresponding solutions have not been determined yet in the prior art, so that inconvenience is brought to practical application, and it is also not beneficial for the network side to save time-frequency resources and electric energy.

Detailed Description

The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.

The method for processing the MBMS statistics message provided by the present invention, as shown in fig. 1, mainly includes the following steps:

step 101, a network side configures a statistical message for performing feedback statistics on an MBMS service, and carries and transmits the statistical message to a UE corresponding to the MBMS service through an MCCH or BCCH.

The purpose and function of the statistical message in the invention is that the network side is used to inform the UE, and the network side needs to know the receiving condition of one or more MBMS services at the UE side. And the network side sends a statistical message, and after receiving the statistical message, the UE uplinks the statistical message to the network side to feed back information whether the MBMS is being received or not according to the requirement of the statistical message. The invention mainly emphasizes the transmission of the parameters with the purposes and functions, the statistical message is only a name, and all the parameters with the purposes and functions can use the transmission mode of the invention.

In the invention, a network side can respectively configure respective statistical messages for each MBSFN area and send the statistical messages in MBSFN subframes corresponding to the respective MBSFN areas, the respective statistical messages of each MBSFN area only comprise MBMS in the MBSFN area, and the statistical messages of each MBSFN area can be respectively configured in cells overlapped and covered by the MBSFN area; certainly, a common statistics message may also be configured for all MBSFN areas, and at this time, there is only one statistics message in the cell, and the statistics message may include all MBMS services that need to be fed back and counted in one or more MBSFN areas in the cell, and further needs to send the period and location information (radio frame or subframe information) of the common statistics message in the BCCH.

The so-called carrying and sending of the statistical message to the UE through the MCCH specifically includes two ways, which are respectively described as follows:

1. and the network side determines the MBSFN area to which the counted MBMS belongs and the MCCH corresponding to the MBSFN area, and loads the counting message in the MCCH corresponding to the MBSFN area and sends the counting message to the UE. And when the UE receives the counting message in the MCCH, determining which MBMS needs to be subjected to feedback counting by using the MBMS identification in the counting message in the MBSFN area corresponding to the MCCH. If some cells are overlapped and covered by a plurality of MBSFN areas, the cells have a plurality of MCCHs to transmit, and the UE only needs to receive and process all the statistical messages contained in the MCCHs which are interested by the UE.

The network side loads the statistical message in the MCCH corresponding to the MBSFN Area where the MBMS service to be counted is located, the MCCH information forms a message to be sent, the message corresponding to the MCCH information is an MBSFN Area Configuration message (MBSFN Area Configuration message), and the position of the statistical message in the MBSFNArea Configuration message is as follows:

--ASN1START

--ASN1STOP

2. And the network side determines the MBSFN area to which the counted MBMS belongs and the MCCH corresponding to the MBSFN area, and loads the counting message in the MCCH corresponding to the MBSFN area and sends the counting message to the UE. And the statistical message is designed by adopting the following mode and is sent to the UE by the following mode: using the MBMS-SessionInfo-r9 parameter in the pmch-InfoList-r9 in MCCH, the MBMS-SessionInfo-r9 may contain multiple sets, each set containing 3 parameters, tmgi-r9, sessionId-r9, logcalchanneldtity-r 9; these three parameters represent the related information of an MBMS service, which is used to identify an MBMS service, and according to the present invention, a statistical message needs to be added in the MBMS-SessionInfo-r 9. For example, the following illustration is intended to encompass both sets. The parameter MBMS-Session Info-r9 designed according to this invention is as follows:

MBMS-SessionInfo-r9::＝ SEQUENCE{

tmgi-r9 TMGI-r9，

sessionId-r9 OCTET STRING(SIZE(1))

logicalChannelIdentity-r9 INTEGER(0...maxSessionPerPMCH-1)，

statistical messages

sessionId-r9 OCTETSTRING(SIZE(1))

logicalChannelIdentity-r9 INTEGER(0...maxSessionPerPMCH-1)，

}

In this way, the design of the counting message is simple, and only one bit of indication information is needed to indicate whether the MBMS service needs counting. In a specific implementation, the indication information may be only one bit, and when the bit is 1, it indicates that feedback statistics are required for the MBMS service described by 3 parameters (i.e., tmgi-r9, sessionId-r9, and logcalchannnelidentity-r 9) in the set of MBMS-SessionInfo-r9, otherwise, no feedback statistics are required. In addition, the statistic message may further include indication statistic type information for informing the UE that the MBMS service requires simple feedback of whether the UE receives the MBMS service, or feedback of which specific UE is receiving the MBMS service. This implementation requires 2 bits, while indicating whether feedback statistics and feedback statistics type are needed. The statistical message is sent in this way, and the MBMS service identification information does not need to be included in the statistical message, because according to the LTE protocol, one MBMS service has been determined according to the three parameters (i.e., tmgi-r9, sessionId-r9, and logical channelidentity-r9) in the parameter MBMS-SessionInfo-r9, and meanwhile, a statistical message is added to this parameter, and the statistical message is by default to describe whether the MBMS service described by the original three parameters in this parameter needs to be feedback-counted.

The so-called loading and sending the statistical message to the UE corresponding to the MBMS service through the BCCH specifically includes:

1. when the network side configures respective statistical messages for each MBSFN area (namely, the network side configures and transmits the statistical messages by taking the MBSFN area as a unit), the statistical messages are carried in a system information block 13(SIB13) and are transmitted to UE corresponding to the MBMS service as a parameter of MBSFN-AreaInfo-r 9; if there are multiple MBSFN-AreaInfo-r9 in SIB13, the statistical message is configured only in the MBSFN-AreaInfo-r9 corresponding to the MBSFN area to which the counted MBMS service belongs. The position of the statistical message in MBSFN-AreaInfo-r9 is as follows:

--ASN1START

MBSFN-AreaInfoList-r9::＝ SEQUENCE(SIZE(1...maxMBSFN-Area))OF

MBSFN-AreaInfo-r9

MBSFN-AreaInfo-r9::＝ SEQUENCE {

}，

}

--ASN1STOP

2. When a network side configures common statistical messages for all MBSFN areas in a cell, the statistical messages are sent by taking the cell or a base station as a unit, the statistical messages are carried in SIB13 to be used as an independent information element (information element) and sent to UE corresponding to the MBMS, and the statistical messages are at the same positions as the positions of MBSFN-AreaInfoList-r9 and notificationConfig-r9 in SIB 13. The position of this statistical message in SIB13 is as follows:

--ASN1START

SystemInformationBlockType13-r9::＝SEQUENCE{

mbsfn-AreaInfoList-r9 MBSFN-AreaInfoList-r9，

notificationConfig-r9 MBMS-NotificationConfug-r9，

statistical messages

}

--ASN1STOP

In this mode, after receiving SIB13, UE acquires the statistical message therein, acquires the MBMS service identifier that needs to be counted from the statistical message, further confirms to which MBSFN area the service belongs to, and then determines whether the service is a service being received by UE itself or a service that is interested by UE itself, and if so, UE sends uplink feedback information to the network side.

Step 102, the network side detects the feedback of the UE and analyzes the UE receiving condition of the MBMS service.

The operation of step 102 may be selected from the following two detection analysis methods:

the first detection mode is that the network side detects the data transmission energy of the UE on the uplink feedback resource distributed for the MBMS service, if the data transmission energy of the UE exceeds the set energy threshold value, the UE is determined to receive the MBMS service; otherwise, no UE is considered to receive the MBMS service. Wherein, the energy threshold value can be set according to simulation. The operation of detecting the energy of the data sent by the UE specifically includes: and performing correlation operation on the sequence requiring the UE uplink feedback and the received sequence requiring the UE uplink feedback, and taking the result of the correlation operation as the energy of the UE sending data.

The second detection mode is that the network side receives the sequence of UE uplink feedback on the uplink feedback resource distributed for the MBMS service, and distributes uplink physical resource for MBMS service feedback to each UE of the uplink synchronization after determining that the UE completes the uplink synchronization according to the sequence of the UE feedback; and the network side analyzes and processes the uplink feedback information sent by the UE through the uplink physical resource to obtain the data fed back by the UE. Of course, if the uplink feedback information sent by the UE carries the identification information of the UE itself, the network side may also know which UE is receiving the MBMS service.

For the two detection and analysis methods, the network side can determine which detection method is used according to the statistical requirements. If the network side only needs to know whether the UE receives the MBMS service or not, the network side uses a first detection mode; if the network side wants to know which UE is receiving the MBMS service, the network side uses the second detection mode or preferentially uses the first detection mode, when the conclusion obtained by the first detection mode is that the UE is receiving, the network side continues to use the second detection mode, otherwise, the network side stops detecting. Here, the detection principle of the second detection method is similar to that of the first detection method.

In addition, the network side of the invention comprises the following devices: a Multi-cell Coordination Entity (MCE), an evolved base station (eNB), a Relay station (Relay), a Broadcast Multicast Service Center (BMSC), a BMSC gateway (BMSC GW), and so on. The method for processing the MBMS statistics message is further described in detail with reference to specific embodiments.

In the first embodiment of the present invention, it is assumed that in a certain scenario where MBSFN area overlapping coverage does not occur, that is, only one MBSFN area in a certain geographic area individually covers all cells in the geographic area. When the BMSC of the network side determines to perform feedback statistics on a certain MBMS, the MCE of the network side configures the statistics information of the MBMS, the configured statistics information is sent to the eNB as the information in the MCCH, and the eNB sends the information to the UE. The statistical messages should be carried in the MCCH as parameters equivalent to the parameters common sf-Alloc-r9, common sf-AllocPeriod-r9 and pmch-InfoList-r9 in the existing MCCH. Since the present embodiment belongs to the case of single MBSFN area coverage, the procedure of selecting MCCH is not required.

In addition, since a new MCCH transmission mechanism is introduced in a Long Term Evolution (LTE) system, that is, the MCCH is transmitted in an MBSFN manner, it is required that statistical messages must be uniformly transmitted in the MCCH of each cell in the entire MBSFN area, and the content in the MCCH of each cell is completely the same. For the situation, the invention preferably configures the statistical message in the MCCH through the MCE corresponding to the MBSFN to which the MBMS service belongs, and the MCE configures the statistical message and then sends the configured statistical message to the relevant eNB; and the eNB generates final MCCH information according to the relevant configuration information sent by the MCE, wherein the final MCCH information comprises the statistical message and then sends the statistical message to the UE. Of course, the MCE may also send only an MBMS service identifier (service ID) that needs to perform feedback statistics to the relevant eNB (or other identifiers that can be identified by the eNB), and then the eNB generates a statistics message for the MBMS service and sends the statistics message to the UE as a part of the MCCH information. The two sections of descriptions give the flow of configuring and sending the statistical message, that is, after receiving the notification of the upper network element, the MCE generates the statistical message for the MBMS service that needs to be fed back for statistics, and sends the generated statistical message to all relevant enbs in the MBSFN area to which the MBMS service belongs; the eNB then sends a corresponding statistics message to the UE.

In the second embodiment of the present invention, it is assumed that in a certain scenario where MBSFN area overlapping coverage occurs, that is, a plurality of MBSFN areas overlap and cover all (or part) cells in a certain geographic area, then the all (or part) cells are referred to as occurring MBSFN area overlapping coverage. When a network side determines to perform feedback statistics for a certain MBMS service, it needs to determine an MBSFN area to which the MBMS service belongs and an MCCH corresponding to the MBSFN area, and sends a configured statistical message to a UE through an eNB as information in the MCCH corresponding to the MBSFN area to which the MBMS service belongs. The statistical messages should be carried in the MCCH as parameters equivalent to the parameters common sf-Alloc-r9, common sf-AllocPeriod-r9 and pmch-InfoList-r9 in the existing MCCH. Since this embodiment is a case of overlapping coverage of multiple MBSFN areas, the network side needs to configure and send a statistical message of the MBMS service in the MCCH corresponding to the MBSFN area to which the counted MBMS service belongs; in this way, the statistical message is transmitted on an MCCH basis in MBSFN areas, and only the statistical message of the MBMS service in the area can be transmitted in each MBSFN area. The description in this section gives the flow of configuration and transmission of the statistical message in the MBSFN area overlapping coverage, that is, after receiving the notification of the upper network element, the MCE generates the statistical message for the MBMS service that needs to be fed back for statistics, and determines the MBSFN area information transmitted by the statistical message or the MCCH information transmitted by the statistical message; then, the generated statistical message is sent to all related eNBs in the MBSFN area to which the MBMS belongs; and the eNB sends the corresponding statistical message to the UE.

In addition, because a new MCCH transmission mechanism is introduced in the LTE system, i.e. the MCCH is transmitted in the MBSFN manner, it is required that the statistical message must be uniformly transmitted in the MCCH of each cell in the entire MBSFN area, and the contents in the MCCH of each cell are completely the same. For the situation, the invention preferably configures the statistical message in the MCCH through the MCE corresponding to the MBSFN to which the MBMS service belongs, and the MCE configures the statistical message and then sends the configured statistical message to the relevant eNB; and the eNB generates final MCCH information according to the relevant configuration information sent by the MCE, wherein the final MCCH information comprises the statistical message and then sends the statistical message to the UE. Of course, the MCE may also send only the MBMS service identifier that needs to perform feedback statistics to the relevant eNB (or other identifiers that can be identified by the eNB), and then the eNB generates a statistics message for the MBSM service and sends the statistics message to the UE as a part of the MCCH information.

In the third embodiment of the present invention, the transmission of the statistics message is described to be carried by a System Information Block (SIB) in the BCCH, specifically, carried by SIB 13.

When a network side determines to perform feedback statistics on a certain MBMS service, configure a statistics message of the MBMS service, and carry the statistics message in an SIB13, the specific carrying manner includes the following two manners:

one is that each MBSFN area is configured with its own unique statistical message, which is only the statistical message of the MBMS service in the MBSFN area. When the network side sends the statistical message by taking the MBSFN area as a unit, the statistical message is carried in SIB13 and is sent to the UE as a parameter of MBSFN-AreaInfo-r 9. If there are multiple MBSFN-AreaInfo-r9 in SIB13, the statistical message is configured only in MBSFN-AreaInfo-r9 corresponding to the MBSFN area to which the MBMS service belongs, and the statistical message is used as an information element (information element) in SIB 13.

And the other is that all MBSFN areas configure a common statistical message, and the statistical message includes the MBMS services to be counted in all MBSFN areas to which the cell belongs. When the network side configures and sends the statistical message by taking a cell (or a base station) as a unit, the statistical message is configured by the base station to which the cell belongs, and is carried in the SIB13 as an independent information unit, and the statistical message is the parameter of the same position as the mbsfn-AreaInfoList-r9 and the notifiationConfig-r 9.

The advantage of using cell (or base station) unit to transmit the statistic message is that the network side only transmits the statistic message for the specific cell (or base station) that may not have the UE receiving the MBMS service, so that other cells (or base stations) in the entire MBSFN area are not affected. Such applications have a high flexibility, for example: for a cell with a small number of users (e.g., a cell in a suburban area), independent feedback statistics may be performed.

In the fourth embodiment of the present invention, the network side sends the statistical message, and after the UE feeds back, the network side detects and analyzes the feedback information of the UE.

Fig. 2 and fig. 3 respectively show basic flowcharts of this embodiment, where a network side sends a statistical message configured for a certain MBMS service according to the foregoing embodiment, and after receiving the statistical message from the network side, according to a requirement of the statistical message, the UE sends uplink feedback information (generally, a specified sequence may also be a sequence set) required by the network side on uplink feedback resources allocated by the statistical message or uplink feedback resources agreed in advance for the counted MBMS service, and the network side receives uplink feedback information of the relevant UE on the allocated resources. The specific processing of the network side is divided into the following two modes, and the network side selects different detection modes according to different statistical requirements.

The first detection mode: as shown in fig. 2, first, the network side sends a statistic message to the UE (step 201); secondly, the UE sends a feedback sequence on a pre-agreed or statistic message allocated uplink feedback resource (step 202), where the resource is a resource provided by the network side for uplink feedback of the MBMS service, and specifies a feedback sequence for the MBMS service, and all UEs (including an RRC _ IDLE mode and an RRC _ CONNECTED mode, and the UEs in the IDLE mode do not need to perform uplink synchronization) that are receiving the MBMS service send the feedback sequence on the resource; finally, the network side detects the energy (or power, which is described by taking energy as an example later) of the received sequence on the resource where the UE sends the uplink feedback information. The method for detecting energy is specifically that a network side uses a sequence requiring uplink feedback of the UE and a sequence received by the network side for uplink feedback of the UE to perform correlation operation, and a result of the correlation operation can be used as an energy value received on the resource, so that the obtained energy value is compared with a threshold of a set energy value, if the result is higher than the set energy threshold, the network side judges that the energy of the data fed back by the UE for the uplink of the MBMS service is detected on the resource, and therefore the UE is considered to receive the MBMS service. Otherwise, no UE is considered to receive the MBMS service. Optionally, after the statistical analysis operation is completed, the network side may notify the UE that the feedback statistics stops (step 203).

The second detection mode is as follows: firstly, the network side sends a statistical message to the UE (step 301); secondly, the UE sends a feedback sequence on the uplink feedback resource allocated by the statistical message or agreed in advance (step 302), the network side detects the sequence fed back by the UE on the resource where the UE sends the uplink feedback information, the used detection mode has the same principle as the first detection mode, that is, after the received information and the known sequence are subjected to correlation operation, the energy threshold is judged, and only the sequences used for performing the correlation detection are different, and this step mainly helps the UE in IDLE mode to complete uplink synchronization; thirdly, the network side allocates uplink physical resources for MBMS service feedback to each UE that has been synchronized in uplink (step 303), and then the UE sends uplink feedback information to the network side on the allocated resources (step 304); and the network side receives and decodes the uplink feedback information, so that the data sent by the UE is acquired. The network side receives uplink feedback data of the UE on the allocated resources, and then performs related analysis processing on the data, including channel estimation, decoding processing and the like, so as to obtain the data fed back by the UE. According to the data fed back by the UE, the network side can at least know that the UE is receiving the MBMS service. Of course, if the data fed back by the UE further includes UE identification information, the network side may also know that the UE is receiving the MBMS service. Optionally, after the statistical analysis operation is completed, the network side may notify the UE that the feedback statistics stops (step 305).

The network side determines which receiving detection mode is preferentially used according to different statistical requirements and by combining with a corresponding MBMS service feedback mechanism adopted by the network side. When the network side only needs to know whether a certain MBMS is received or not by the UE, the network side preferentially uses the first detection mode, namely the network side uses the sequence allocated to the MBMS to perform the correlation operation with the received data fed back by the UE, and detects the data energy in the sequence. The first detection mode has a high detection speed relative to the second detection mode, and the detection process is simple and easy to realize. Optionally, after the network side has obtained the information that the UE is receiving the MBMS service, the network side may notify the UE, and the counting process is finished, so that the UE that has not yet come to feedback may no longer need to send uplink feedback information. When the network side needs to know which UEs are receiving the MBMS service, as shown in fig. 4, the network side preferentially uses the first detection method, if the result obtained by the first detection method is that there is a UE on the resource that has sent uplink feedback data for the MBMS service (i.e., the detection energy exceeds the set threshold), the network side continues to perform detection of the second detection method, otherwise, the network side does not continue to perform detection on the resource.

It should be noted that, when the feedback mode specified by the network side is: allocating different resources for the MBMS services needing statistical feedback, and allocating different feedback sequences for different MBMS services; and when the feedback mode specified by the network side is as follows: different resources are allocated to the MBMS services which need to be subjected to statistical feedback, and the same feedback sequence is allocated to the different MBMS services. In these two cases, only one MBMS service can be known whether there is a UE receiving the MBMS service or not, so the network side uses the first detection method, that is, the network side performs correlation operation using the sequence allocated to the MBMS service and the received data fed back by the UE to detect the data energy therein. The first detection mode has a high detection speed relative to the second detection mode, and the detection process is simple and easy to realize. Optionally, after the network side has obtained the information that the UE is receiving the MBMS service, the network side may notify the UE, and the counting process is finished, so that the UE that has not yet come to feedback may no longer need to send uplink feedback information.

Corresponding to the processing method of the MBMS statistical message, the present invention further provides a processing apparatus of the MBMS statistical message, including: the device comprises a message configuration module, a message sending module and a detection analysis module. The message configuration module is used for configuring a statistical message for carrying out feedback statistics on the MBMS service. A message sending module, configured to determine an MBSFN area to which the counted MBMS service belongs and an MCCH corresponding to the MBSFN area, and send the counting message to the UE by bearing the counting message in the MCCH corresponding to the MBSFN area; or the statistical message is carried by BCCH and sent to UE. And the detection analysis module is used for detecting the feedback of the UE and analyzing the UE receiving condition of the MBMS service.

Preferably, the message sending module is further configured to, when the MBSFN area is taken as a unit and the statistical message is sent through BCCH bearer, bear the statistical message in SIB13 as a parameter of MBSFN-area info-r9 and send the parameter to the UE corresponding to the MBMS service; when a cell or a base station is taken as a unit and the statistic message is sent through BCCH bearer, the statistic message is carried in the SIB13 and is sent to the UE corresponding to the MBMS as an independent information unit.

The detection analysis module is further used for detecting the feedback of the UE by adopting a first detection mode and judging whether the UE receives the MBMS according to the detection result of the first detection mode; and when the UE is judged to receive the MBMS service, analyzing the uplink feedback information sent by the UE by adopting a second detection mode to obtain the data fed back by the UE.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
