Description

User equipment, network equipment, system and method for MBMS measurement filtering

[Technical Field]

The present invention relates to the field of communications, and in particular, to a user equipment, a network device, a system, and a method for MBMS measurement filtering.

【Background technique】

The eMBMS (Ehanced Multimedia Broadcast/Multicast Service) technology is a technology that simultaneously transmits the same service to multiple UEs (User Equipments) using a broadcast channel. A group of UEs receiving the same service use the same downlink configuration for service reception, and it is not necessary to establish their own link for each UE. The transmission of the eMBMS is in a time division manner. A PMCH (Physical Multicast Channel) occupies several subframes, and the cycle is cyclic. Each cycle is called an MSI (Multicast Channel Scheduling Information) cycle, and the first subframe of each cycle transmits MSI. MSI is used to indicate which services are transmitted on which subframes. MTCH (Multicast Traffic Channel) is used to transmit specific services. Each service occupies 1 to more subframes. As shown in Figure 1, an MBSFN (Multicast Broadcast Single Frequency Network) area can have one or more PMCHs. Each PMCH has its own MSI period. These periods can be the same or different. The UE reads the correspondence between the PMCH and the service from the MCCH (Multicast Control Channel), and then determines the PMCH to be read according to the read service. For example, if the UE determines that the service 1 and the service 3 need to be read, the UE 1 and the service 3 are respectively mapped to the PMCH 1 and the PMCH 2 according to the configuration, and the UE reads the PMCH 1 and the PMCH 2 in the first subframe of each PMCH cycle. The MSI, according to the MSI, knows in which subframes the service 1 and the service 3 are transmitted. Then read the services corresponding to these subframes. If the MSI indicates that the service data is not available in the current period, the UE may not need to read the remaining subframes on the PMCH in the current period.

When the UE moves within the MBSFN area, the MBMS service is not required to establish a connection with the network. However, when the UE moves out from the MBSFN area, it is necessary to establish a connection with the network to continue data reception without the MBSFN coverage. In the prior art, the network side may configure a measurement type, such as a period or an event type, for the UE, and the UE performs measurement and filtering according to the type, and according to the result, determines whether a connection needs to be established to continue receiving data.

When the MBMS service that the UE wants to read has no data to be transmitted, the UE will follow the MSI cycle. Read the sub-frame where the MSI is located. If there is data transmission, the UE also reads the subframe of the data transmission. When the measurement of the MBMS service is performed, the UE receives different subframes according to the MSI of the MBMS service to be read, and the received subframes are also different, so that the period of the physical layer reporting to the layer 3 is not fixed. The filter coefficient configured on the network side may not be suitable for the period reported by the physical layer of the current UE to the layer 3, so that the filtering is inaccurate.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The purpose of Layer 3 filtering in MBMS measurement filtering is to filter out the fluctuations, the sliding window filtering formula used, the weighting coefficient is configured by the measurement control, and the layer three filtering formula:

F _n = (\ - a) - F _n _ _x + α · Μ _η

Where F _n current measurement result, last measurement result, a measurement quantity reported by the M _n physical layer, a = l/2 ^(k/2) , k is the filter coefficient configured in the measurement control, if k = 0 means No layer three filter Wave.

Please refer to FIG. 2. FIG. 2 is a schematic diagram showing the structure of a user equipment for MBMS measurement filtering according to the present invention. As shown in FIG. 2, the user equipment 10 includes: a receiving module 101, a processing module 102, a measurement module 103, and a filtering module 104. The processing module 102 and the measurement module 103 are respectively connected to the receiving module 101, and the filtering module 104 is connected to the processing module 102 and the measuring module 103. The receiving module 101 is configured to receive measurement events and filter coefficient information of the network device configuration. The processing module 102 is configured to acquire period information related to the MBMS service, and determine the filter coefficient according to the period information and the filter coefficient information. Measurement module 103 is used to perform physical layer measurements based on measurement events. The filtering module 104 is configured to filter the measurement result reported by the physical layer according to the filter coefficient.

In a more specific embodiment, the measurement event of the network device configuration received by the receiving module 101 can be a periodic type measurement, or an event type measurement. If it is an event type measurement, it is necessary to carry the corresponding measurement threshold. The processing module 102 can determine the filter coefficients in three ways:

1) The filter coefficient information received by the receiving module 101 has a plurality of filter coefficients, and each filter coefficient includes corresponding first cycle information. For example, when the first period information is 80 ms, the corresponding filter coefficient K0; when the first period information is 160 ms, the corresponding filter coefficient K1; when the first period information is 320 ms, the corresponding filter coefficient K2; the first period information is greater than 320 ms When corresponding to the filter coefficient K3. In the embodiment of the present invention, the larger the first period information is, the smaller the corresponding filter coefficient is, but the value of the first period information is not necessarily fixed, and may be changed according to the application scenario.

The processing module 102 reads the minimum MSI period corresponding to the MBMS service, selects the first period information according to the minimum MSI period, and selects the corresponding filter coefficient according to the first period information. Specifically, the processing module 102 selects first period information equal to the minimum MSI period, or selects first period information that is a multiple of the minimum MSI period, and then selects a corresponding filtering coefficient according to the first period information. The MBMS service includes an MBMS service that satisfies at least one of the following conditions: an MBMS service being received; an MBMS service belonging to a predetermined MBSFN area; an MBMS service carrying a predetermined type of service, and a predetermined type of service including a group communication service or a public security class business. For example, if the minimum MSI period of the user equipment 10 is 80 ms, the filter coefficient K0 corresponding to the first period information is 80 ms. The minimum MSI period of the user equipment 10 is 640 ms, and the filter coefficient K3 corresponding to the first period information greater than 320 ms is found. Of course, the minimum MSI period *5 can also be used to find the corresponding filter coefficient corresponding to the first period, which is not limited herein, and the specific multiple is not limited.

2) The processing module 102 reads the minimum MSI period corresponding to the MBMS service, and determines the filter coefficient according to the minimum MSI period, the filter coefficient information, and the reference period information. Specifically, the filter coefficient information Including a reference filter coefficient, the processing module 102 scales the reference filter coefficients according to the minimum MSI period and the reference period information, or exponentially scales to determine the filter coefficients. The reference period information is a predefined period, or a minimum MSI period in the PMCH list, or reference period information of the network device configuration received by the receiving module 101. For example, k = first measurement period/reference period information *kl, where k is the finally determined filter coefficient and kl is the reference filter coefficient included in the filter coefficient information. Optionally, the processing module 102 further receives a PMCH list sent by the network device by using a multicast control channel to determine reference period information, where each PMCH corresponds to one MSI period.

The processing module 102 obtains a first measurement period, where the first measurement period is a period in which the physical layer reports the measurement result to the layer 3 when the measurement accuracy is satisfied. For example, the MBMS service being read by the user equipment 10 is carried on the PMCH with an MSI period of 80 ms. When the service has no data, the user device 10 only reads the MSI. Assuming that the user equipment 10 can provide a measurement accuracy measurement value to Layer 3 every 5 subframes read, the first measurement period of the user equipment 10 is 5*MSI. When there is service data arrival, assuming that there are two subframes carrying the service in each MSI period, each MSI period of the user equipment 10 can measure 3 subframes, and the time required to read 5 subframes is 5/3. *MSI, the first measurement period is 5/3*MSI. The processing module 102 then determines the filter coefficients based on the first measurement period, the filter coefficient information, and the reference period information. Specifically, the filter coefficient information includes a reference filter coefficient, and the processing module 102 scales the reference filter coefficients according to the first measurement period and the reference period information, or exponentially scales to determine the filter coefficients. The reference period information is a predefined period, or reference period information of the network device configuration received by the receiving module 101. For example, 1^=first measurement period/reference period information *kl, where k is the finally determined filter coefficient, and kl is the reference filter coefficient included in the filter coefficient information.

In the embodiment of the present invention, the receiving module 101 receives the measurement event and the filter coefficient information configured by the network device, the processing module 102 obtains the cycle information related to the MBMS service, and determines the filter coefficient according to the cycle information and the filter coefficient information, and the measurement module 103 is configured according to the The measurement event is subjected to physical layer measurement, and the filtering module 104 filters the measurement result reported by the physical layer according to the filter coefficient, so that the configured filter coefficient is suitable for the period reported by the physical layer to the layer 3, thereby solving the problem that the MBSM service filtering is inaccurate.

2) The processor 112 reads the minimum MSI period corresponding to the MBMS service, and determines the filter coefficient according to the minimum MSI period, the filter coefficient information, and the reference period information. Specifically, the filter coefficient information includes a reference filter coefficient K1, and the processor 112 scales the reference filter coefficients according to the minimum MSI period and the reference period information, or exponentially scales to determine the filter coefficients. The reference period information is a predefined period, or a minimum MSI period in the PMCH list, or reference period information of the network device configuration received by the transceiver 111. Optionally, the processor 112 further receives a PMCH list sent by the network device through the multicast control channel to determine reference period information, where each PMCH corresponds to one MSI period.

The processor 112 obtains a first measurement period, where the first measurement period is a period in which the physical layer reports the measurement result to the layer 3 when the measurement accuracy is satisfied, and then determines the filter coefficient according to the first measurement period, the filter coefficient information, and the reference period information. . Specifically, the filter coefficient information includes a reference filter coefficient K1, and the processor 112 scales the reference filter coefficients according to the first measurement period and the reference period information, or exponentially scales to determine the filter coefficients. The reference period information is a predefined period, or reference period information of the network device configuration received by the transceiver 111.

S11: Receive measurement event and filter coefficient information of the network device configuration. Wherein, the measurement event can be a periodic measurement or an event measurement. If it is an event type measurement, it is necessary to carry the corresponding measurement threshold. When the measurement event meets the trigger condition, the measurement result is reported to the network device, so that the network side learns the MBMS reception quality of the user equipment according to the measurement result or triggers the user equipment to perform a predetermined action, for example, reporting that the MBMS signal is unavailable to the upper layer of the user equipment, or MBMS signal recovery is available so that the user's upper layer determines whether to perform an MBMS reception interrupt or recovery operation.

S12: Obtain period information related to the MBMS service, and determine a filter coefficient according to the period information and the filter coefficient information.

In S12, the filter coefficients are determined in three ways:

1) The received filter coefficient information of the network device configuration has a plurality of filter coefficients, and each filter coefficient includes a corresponding first cycle information. The larger the first period information, the smaller the corresponding filter coefficient. S12 includes: reading a minimum MSI period corresponding to the MBMS service, selecting first period information according to a minimum MSI period, and selecting a corresponding filter coefficient according to the first period information. Specifically, the first period information equal to the minimum MSI period is selected, or the first period information that is a multiple of the minimum MSI period is selected, and the corresponding filter coefficient is selected according to the first period information. The MBMS service includes an MBMS service that satisfies at least one of the following conditions: an MBMS service being received; an MBMS service belonging to a predetermined MBSFN area; an MBMS service carrying a predetermined type of service, and a predetermined type of service including a group communication service or a public security class Business and other business.

2) Read the minimum MSI period corresponding to the MBMS service, and determine the filter coefficient according to the minimum MSI period, the filter coefficient information, and the reference period information. Specifically, the filter coefficient information includes a reference filter coefficient, and the processing module 102 scales the reference filter coefficients according to the minimum MSI period and the reference period information, or exponentially scales to determine the filter coefficients. The reference period information is a predefined period, or the smallest MSI period in the PMCH list, or the reference period information of the received network device configuration. Optionally, the S12 further includes: receiving, by the network device, the PMCH list sent by using the multicast control channel, to determine reference period information, where each PMCH corresponds to one MSI period.

3) Obtaining a first measurement period, where the first measurement period is a period in which the physical layer reports the measurement result to the layer 3 when the measurement accuracy is satisfied. The filter coefficients are determined according to the first measurement period, the filter coefficient information, and the reference period information. Specifically, the filter coefficient information includes a reference filter coefficient, and the reference filter coefficient is scaled according to the first measurement period and the reference period information, or is exponentially scaled to determine a filter coefficient. The reference period information is a predefined period, or reference period information of the received network device configuration. S13: Perform physical layer measurement according to the measurement event.

S14: Filter the measurement result reported by the physical layer according to the filter coefficient.

In the embodiment of the present invention, the measurement event and the filter coefficient information configured by the network device are received, and the cycle information related to the MBMS service is acquired, and the filter coefficient is determined according to the cycle information and the filter coefficient information, and the physical layer measurement is performed according to the measurement event. Then, the measurement result reported by the physical layer is filtered according to the filter coefficient, so that the configured filter coefficient is suitable for the period reported by the physical layer to the layer 3, thereby solving the problem that the MBSM service filtering is inaccurate.

Please refer to FIG. 7. FIG. 7 is a schematic diagram of a method for MBMS measurement filtering according to a second embodiment of the present invention. As shown in Figure 7. The MBMS measurement filtering method includes:

S21: Configure measurement events and filter coefficient information to the user equipment.

The measurement result reported by the physical layer is filtered.

In S22, the PMCH list is also sent to the user equipment by using the multicast control channel, where each PMCH corresponds to one MSI period, so that the user equipment determines the reference period information.

In the embodiment of the present invention, the filter coefficient information may have a plurality of filter coefficients, each filter coefficient includes a corresponding first cycle information, and the larger the first cycle information is, the smaller the corresponding filter coefficient is, so that the user equipment is based on The period information related to the MBMS service selects the first period information, and selects a corresponding filter coefficient according to the first period information. The filter coefficient information may also include only a reference filter coefficient to cause the user equipment to scale the reference filter coefficients according to the period information and reference period information associated with the MBMS service, or to scale exponentially to determine the filter coefficients. The reference period information is a pre-defined period, or reference period information configured to the user equipment. If the PMCH list is transmitted to the user equipment through the multicast control channel, the reference period information may also be the smallest MSI period in the PMCH list. In this way, the configured filter coefficients can be adapted to the period in which the physical layer reports to the layer three, thereby solving the problem that the MBSM service filtering is inaccurate.

In the embodiment of the present invention, the network device may be any one of a Node B, an eNode B, a BSC, and an RNC. In summary, the present invention receives the measurement event and the filter coefficient information of the network device configuration by the receiving module, the processing module acquires the cycle information related to the MBMS service, and determines the filter coefficient according to the cycle information and the filter coefficient information, and the measurement module according to the measurement event The physical layer measurement is performed, and the filtering module filters the measurement result reported by the physical layer according to the filter coefficient, so that the configured filter coefficient is suitable for the period reported by the physical layer to the layer 3, thereby solving the problem that the MBSM service filtering is inaccurate.
