MBMS is a technology for transmitting data from a data source to multiple UEs (User Equipments) by sharing network resources. It can effectively utilize network resources while providing multimedia services, and realize broadcast of higher-speed multimedia services. And multicast. The technology types in which MBMS transmits data from one data source to multiple UEs include SC-PTM (Single Cell Point To Multiploint) scheme of air interface broadcast transmission.

For a base station that adopts the SC-PTM scheme, one SC-MCCH (Single Cell Multicast Control Channel) is allocated to each cell, and multiple SC-MTCHs (Single Cell Multicast Transport Channel) Broadcast traffic channel). The SC-MCCH control information carries the service data of each SC-MTCH, and the UE in the cell can obtain the service data of the SC-MTCH corresponding thereto in the successfully parsed SC-MCCH control information, so that the user can The SC-MTCH service data correctly demodulates and decodes service data, such as video resources. The base station periodically sends the SC-MCCH control information, and the SC-MCCH control information may be located at the start time of the modification period (MP) and the repetition period (RP). One MP may include multiple RPs, as shown in the figure. As shown in Figure 1, an MP includes 2 RPs. When the user does not successfully parse the SC-MCCH control information in the initial repetition period of the MP, the user acquires the SC-MCCH control information again in the initial repetition period of the next MP. .

detailed description

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 obvious that the described embodiments are only a part of the embodiments of the present invention, but not all 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.

With the emphasis on public safety, MC-PTT (Mission Critical Push To Talk), MC-Vedio (Mission Critical Video Service), MC-Data (Mission Critical Data Service, A strong demand for real-time group communication services, such as mission-critical data services, the 3GPP organization introduced an air interface broadcast transmission alternative SC-PTM in its R13 protocol to flexibly and dynamically transmit various MBMS services. For example, for the MC-PTT service, that is, the group call service, the MBMS bearer may be used. Before the group call data transmission, the session start notification is sent, and after the group call data transmission is completed, the MBMS session ends.

For a cell that uses the SC-PTM scheme, one SC-MCCH (Single Cell Multicast Control Channel) and a plurality of SC-MTCH (Single Cell Multicast Transport Channel) are allocated for each cell. Multicast traffic channel). The SC-MCCH control information carries control information of each SC-MTCH service related information.

Both the SC-MCCH and the SC-MTCH are mapped to the downlink shared transport channel DL-SCH, that is, the SC-MCCH control information and the SC-MTCH service related information can be obtained through the downlink shared transport channel DL-SCH, as shown in FIG. 2, A schematic diagram of mapping an SC-MCCH and an SC-MTCH to a downlink shared transport channel DL-SCH.

The process of the user equipment UE receiving the SC-PTM data (ie, the SC-MCCH control information) is as follows: the base station sends the SIB20 message to the user equipment UE, where the SIB20 message includes the location information of the SC-MCCH control information, and the SC-MCCH The modification period of the control information, the repetition period of the SC-MCCH control information, and the SC-MCCH control information are located in the repetition period. The location information of the subframe, the user can obtain the location information of the SC-MCCH control information through the SIB20 message, and then obtain the SC-MCCH control information from the location information of the subframe corresponding to the start of the repetition period of the modification period, and parse the information. The SC-MCCH control information, when the parsing is successful, acquires SC-MTCH service related information corresponding to the user equipment UE from the SC-MCCH control information; the SC-MCCH control information may include the MBMS service ID and the SC-MTCH service related information. Corresponding relationship, the user equipment may obtain corresponding SC-MTCH service related information from the SC-MCCH control information according to the MBMS service ID. If the parsing fails, the SC-MCCH control information is obtained from the initial repetition period of the next modification period, and parsed until the SC-MCCH control information is successfully parsed.

The method for parsing SC-MCCH control information in the prior art has the following disadvantages:

First, the SC-MCCH control information carried in the subframe corresponding to each repetition period in the same modification period may be the same, and the SC-MCCH control information carried in the subframe corresponding to each repetition period may be the same and may be different. The method for parsing the SC-MCCH control information in the prior art is that only one repetitive period of SC-MCCH control information can be obtained for each modification period. When the SC-MCCH control information fails to be parsed, the modification period is no longer used. Acquiring the SC-MCCH control information in other repetition periods, and directly acquiring the SC-MCCH control information from the initial repetition period of the next modification period, and parsing if the SC-MCCH control information included in the two modification periods is the same There will be no problem. If the SC-MCCH control information contained in the two modification cycles is different, the SC-MCCH control information that has not been successfully resolved will be missed.

Then, in the method for parsing the SC-MCCH control information in the prior art, when the base station broadcasts the session start message to the user equipment UE, the user equipment UE still needs to acquire the SC-MCCH control information after receiving the session start message, and After the successful analysis, it is determined whether the SC-MCCH service-related information corresponding to the MBMS service ID of the user equipment UE is included in the SC-MCCH control information. When included, the user equipment UE determines that the session starts, and when not included, the user equipment UE It is determined that the session has not started. Therefore, if the user equipment UE does not successfully parse the SC-MCCH control information, the user equipment UE session start time is also delayed.

If the base station receives the session end command sent by the core network (which may be a session end command for one or more user equipments), the corresponding user equipment UE is no longer included in the SC-MCCH control information generated by the base station. Corresponding SC-MTCH service related information, when the user sets If the SC-MCCH service-related information corresponding to the MBMS service ID is not detected, the user equipment UE ends the session, and the user does not successfully parse the SC-MCCH control information. The SC-MCCH control information is obtained in the subframe corresponding to the initial repetition period of the next modification period. As shown in FIG. 3, the embodiment of the present application includes two repetitions in a modification period (MP). The period (Repetition Period, RP) is taken as an example. The solid rectangle is the position of the SC-MCCH control information in the repetition period, and the four SC-MCCH control information in the modification period 1 and the modification period 2 are included with the user equipment UE. The SC-MTCH service-related information corresponding to the MBMS service ID, and the SC-MCCH control information in the modification period 3 and the modification period 4 are SC-MTCH service-related information that does not include the MBMS service ID of the user equipment UE. The modification period 1 includes a repetition period 11 and a repetition period 12; the modification period 2 includes a repetition period 21 and a repetition period 22; the modification period 3 includes a repetition period 31 and a repetition period 32; the modification period 4 includes a repetition period 41 and a repetition period 42 if the user When the device fails to parse the SC-MCCH control information obtained from the repetition period 31 (ie, the repetition period of the modification period 3), the user equipment UE acquires the SC-MCCH control information from the subframe corresponding to the repetition period 41, and If the resolution is successful, the end time t1 of the session duration of the user equipment UE is as shown in FIG. 3, and the actual session duration between the user equipment UE and the base station is t0, and the session between the user UE and the base station. The duration (if successfully decoded at repetition period 31) is t2.

As the session duration between the user equipment UE and the base station is extended, the resolution time of the user equipment UE for the SC-MCCH control information is increased, that is, the data processing time of the user equipment UE is increased, and the power consumption of the user equipment UE is consumed.

In summary, the method for parsing SC-MCCH control information in the prior art has the following disadvantages:

The unresolved SC-MCCH control information may be missed.

Delaying the user equipment UE session start time;

The time when the user equipment UE ends the session is delayed, that is, the session time of the user equipment UE is extended.

To this end, the embodiment of the present application provides a data parsing method, which can be applied to user equipment, such as a smart phone, a walkie-talkie, a smart TV, a computer, a portable android device (PAD), a PDA (Personal Digital). Assistant, Pocket PC, etc. Please refer to FIG. 4 , which is a schematic flowchart of a data parsing method according to an embodiment of the present application. The method includes:

Step S401: Acquire SC-MCCH control information from a subframe corresponding to the target repetition period in the current modification period.

The data parsing method provided by the embodiment of the present application can be applied to various application scenarios, and the following application scenarios are listed below.

The first application scenario: after receiving the change notification of the SC-MCCH control message, the user equipment UE that is interested in the SC-PTM service data may obtain the SC-MCCH from the subframe corresponding to the initial repetition period of the current modification period. Control information. The repetition period 11, the repetition period 21, the repetition period 31, and the repetition period 41 in FIG. 3 are the modification period 1, the modification period 2, the modification period 3, and the start repetition period of the modification period 4, respectively. In the first application scenario, the destination repetition period is the initial repetition period.

The second application scenario is: a user equipment that has the capability of receiving SC-PTM service data, such as a mobile user equipment such as a smart phone or a walkie-talkie, after selecting or reselecting or switching to a cell, at the current TTI (transmission time interval, transmission time) The first repetition period of the current modification period after the interval) corresponds to decoding the SC-MCCH control information at the subframe. Still taking FIG. 3 as an example, assuming that the user equipment is switched to the target cell (ie, the cell where the user equipment is located) by the source cell (ie, the cell where the original user equipment is located), the time of the current modification period received is the modification period. The time of the end of the repetition period 31 of 3, for the user equipment, the first repetition period of the current modification period is the repetition period 32. In the second application scenario, the destination repetition period is the first repetition period of the current modification period after the current TTI (transmission time interval).

The third application scenario is that the user equipment that is receiving the SC-PTM service data can obtain the SC-MCCH control information from the subframe corresponding to the initial repetition period of the current modification period. In the third application scenario, the destination repetition period is the initial repetition period.

Step S402: When parsing the corresponding SC-MCCH control information in the destination repetition period, the corresponding SC-MCCH control information is sequentially obtained from the subframe corresponding to the repetition period of the destination repetition period and parsed until Successfully parsed an SC-MCCH control information.

It is assumed that the modification period includes 5 repetition periods, and is sequentially referred to as a start repetition period, a second repetition period, a third repetition period, a fourth repetition period, and a fifth repetition period, assuming a purpose repetition week The period is the second repetition period, and the “acquiring the SC-MCCH control information from the subframe corresponding to the repetition period of the destination repetition period, respectively, and parsing” means that the child corresponding to the second repetition period first The SC-MCCH control information is obtained in the frame. And parsing, if the parsing is successful, stopping, or acquiring SC-MCCH control information from the initial repetition period of the next modification period and parsing; if the SC-MCCH control information corresponding to the second repetition period fails to parse, Acquiring the SC-MCCH control information in the subframe corresponding to the three repetition period, if the parsing is successful, stopping, or acquiring the SC-MCCH control information from the initial repetition period of the next modification period and parsing; if the third repetition period If the corresponding SC-MCCH control information fails to be parsed, the SC-MCCH control information may be obtained from the subframe corresponding to the fourth repetition period, and parsed. If the parsing is successful, the SC-MCCH control information may be stopped, or may be stopped from the beginning of the next modification period. Acquiring and parsing the SC-MCCH control information in the repetition period; if the SC-MCCH control information corresponding to the fourth repetition period fails to be resolved, the SC-MCCH control information may be obtained from the subframe corresponding to the fifth repetition period, and parsed, if If the parsing is successful, it may be stopped, or the SC-MCCH control information may be acquired and parsed from the beginning of the next modification period.

Because the parsed SC-MCCH control information includes the SC-MTCH service-related information corresponding to the MBMS service ID of the user equipment UE, it indicates that the base station still sends the service data for the user equipment UE, that is, the session between the base station and the user equipment UE. The SC-MCCH control information needs to be continuously obtained. If the SC-MCCH control information corresponding to the MBMS service ID of the user equipment UE is not included in the parsed SC-MCCH control information, the base station and the user are indicated. After the session of the device UE has ended, the SC-MCCH control information can be stopped. Therefore, after the user equipment UE successfully parses the SC-MCCH control information, there are two possibilities, that is, stopping or acquiring the SC-MCCH control information from the initial repetition period of the next modification period and parsing.

Step S403: When the obtained SC-MCCH control information fails to be parsed from the subframe corresponding to the repetition period in the current modification period, the SC is sequentially obtained from each repetition period of the next modification period. - MCCH control information until the SC-MCCH control information is successfully parsed.

In the data parsing method provided by the embodiment of the present application, if the SC-MCCH control information obtained from the destination repetition period in the current modification period is not successfully parsed, the week is repeated from the destination. The SC-MCCH control information is sequentially obtained in the subsequent repetition period, and is parsed until the analysis is successful. If the subframe corresponding to the repetition period in a modification period is not successfully parsed, the next step is from the next. Obtaining the SC-MCCH control information in each repetition period of the modification period until the SC-MCCH control information is successfully parsed, thereby improving the frequency of acquiring and parsing the SC-MCCH control information, and improving the analysis of the SC-MCCH control information. Success rate.

Further, after the user equipment receives the session start message sent by the base station, the user equipment can quickly determine whether the session between the base station and the base station is started, so that the user equipment quickly enters the session with the base station. The state, after the base station ends the session with the user equipment, the user equipment can determine whether the session between the base station and the base station ends by quickly analyzing the SC-MCCH control information, thereby ending the session with the base station as soon as possible. In an application scenario in which the SC-MCCH control information is normally received, the SC-MCCH control information acquired in the subframe corresponding to the destination repetition period in the modification period may be re-corresponding from other repetition periods in the modification period. The SC-MCCH control information is obtained and parsed in the subframe, thereby increasing the number of times the same SC-MCCH control information is acquired and parsed, thereby increasing the probability that the same SC-MCCH control information is successfully parsed, so that the user equipment fails. The probability of parsing and missing the SC-MCCH control information is reduced.

For a person skilled in the art to understand the beneficial effects of the data parsing method provided by the embodiment of the present application, an application scenario in which the base station ends the session with the user equipment is taken as an example for description.

As shown in FIG. 3, if the SC-MCCH control information obtained by the user equipment in the repetition period 31 is not successfully resolved, the SC-MCCH control information may be obtained from the repetition period 32 and parsed, if obtained from the repetition period 32. If the SC-MCCH control information is successfully parsed, the session duration of the user equipment UE is t3, and the session duration is reduced by t1-t3 compared with the prior art.

In this case, the maximum early end session time is: maxTime=MP*10–RP*10 (unit: ms), that is, the session can be terminated by 0~maxTime radio frames in advance. In the formula, MP refers to a modification period. The number of radio frames and RP refers to the number of radio frames included in one repetition period, and the duration of each radio frame is 10 ms.

In order to improve the success rate of the user equipment UE to parse the SC-MCCH control information, the above sequence is divided. Obtaining the SC-MCCH control information from the subframe corresponding to the repetition period of the destination repetition period, and parsing includes:

Determining the currently received current repetition period from the subsequent repetition period of the destination repetition period; acquiring SC-MCCH control information from the subframe corresponding to the current repetition period; and selecting the SC-MCCH corresponding to the current repetition period The control information is soft combined with the at least one failed SC-MCCH control information to obtain target SC-MCCH control information; the target SC-MCCH control information is parsed; when the target SC-MCCH control information is parsed, the Acquiring the SC-MCCH control information in the subframe corresponding to the next repetition period of the current repetition period, and using the next repetition period of the current repetition period as the current repetition period, returning the subframe corresponding to the current repetition period The step of acquiring SC-MCCH control information; determining that the SC-MCCH control information is successfully parsed when parsing the target SC-MCCH control information is successful.

In order to improve the success rate of receiving SC-MCCH control information, the base station generates multiple redundancy versions (RVs) using Turbo channel coding when transmitting SC-MCCH control information, and adopts increments in different repetition periods of the same SC-MCCH change period. The SC-MCCH control information transmission is performed in a redundant manner, that is, different repetition periods are used in different redundancy versions. Redundancy version (RV), that is, the redundant bits generated by the encoder generate 4 redundancy versions according to different starting points, numbered 0, 1, 2, 3. The transmission order of the SC-MCCH control information in different repetition periods is 0, 2, 3, and 1, according to the number of repetition periods. If there are 5 repetition periods, the redundancy version is 0, 2. 3, 1, 0, if there are only 2 repetition periods, the redundancy version order is 0, 2.

When receiving the SC-MCCH control information, the terminal device may perform soft combining on the SC-MCCH control information of different repetition periods in the same modification period. Specifically, if the decoding of the SC-MCCH control information fails in the first repetition period, the corresponding bit of the received unsuccessfully decoded SC-MCCH control information is saved in the buffer, and the second repetition period of the same modification period is received. When the corresponding bit of the SC-MCCH control information is soft-combined with the bit corresponding to the first repetition period SC-MCCH control information in the buffer, and then decoded, if the decoding fails again, the third of the same modification week is received. When the corresponding bit of the SC-MCCH control information in the repetition period is repeated, the corresponding bit and the buffer of the SC-MCCH control information in the third repetition period are The first repetition period of the first two repetitions of the SC-MCCH control information and the corresponding bits of the SC-MCCH control information in the second repetition period are soft combined and then decoded. And so on, until the SC-MCCH control information is decoded successfully.

An incremental redundant transmission method for adding redundant information when a base station transmits SC-MCCH control information in different repetition periods of the same change period, and the terminal device performs soft combining for decoding at the time of reception, and can correct a part of SC-MCCH control information correspondingly The error bit can improve the probability of receiving SC-MCCH control information correctly.

It can be understood that the SC-MCCH control information in each repetition period in the same modification period is the same, and the same but unresolved SC-MCCH control information is compared with the currently obtained unresolved SC-MCCH. After the soft combining of the control information, the analysis of the combined SC-MCCH control information greatly improves the success rate of analyzing the SC-MCCH control information.

Of course, the user equipment can also parse the currently obtained unresolved SC-MCCH control information at a time.

The embodiment of the present application further provides a data parsing apparatus. Referring to FIG. 5, it is a schematic structural diagram of a data parsing apparatus according to an embodiment of the present application. The data parsing apparatus may be applied to a user equipment, where the data parsing apparatus includes: The first obtaining module 51, the second obtaining module 52, and the processing module 53 are:

The first obtaining module 51 is configured to obtain the SC-MCCH control information from the subframe corresponding to the destination repetition period in the current modification period.

The first application scenario: after receiving the change notification of the SC-MCCH control message, the user equipment UE that is interested in the SC-PTM service data may obtain the SC-MCCH from the subframe corresponding to the initial repetition period of the current modification period. Control information. The repetition period 11, the repetition period 21, the repetition period 31, and the repetition period 41 in FIG. 3 are the modification period 1, the modification period 2, the modification period 3, and the start repetition period of the modification period 4, respectively. In the first application scenario, the destination repetition period is the starting weight. Cycle.

The second application scenario is: a user equipment that has the capability of receiving SC-PTM service data, such as a mobile user equipment such as a smart phone or a walkie-talkie, after selecting or reselecting or switching to a cell, at the current TTI (transmission time interval, transmission time) The first repetition period of the current modification period after the interval) corresponds to decoding the SC-MCCH control information at the subframe. Still taking FIG. 3 as an example, assuming that the user equipment is switched to the target cell (ie, the cell where the user equipment is located) by the source cell (ie, the cell where the original user equipment is located), the time of the current modification period received is the modification period. The time of the end of the repetition period 31 of 3, for the user equipment, the first repetition period of the current modification period is the repetition period 32. In the second application scenario, the destination repetition period is the first repetition period of the current modification period after the current transmission time interval TTI.

The second obtaining module 52 is configured to, when parsing the corresponding SC-MCCH control information in the repetition period of the destination, sequentially obtain corresponding SC-MCCH control from the subframe corresponding to the repetition period subsequent to the destination repetition period The information is parsed until a SC-MCCH control message is successfully parsed.

It is assumed that the modification period includes five repetition periods, and is sequentially referred to as a start repetition period, a second repetition period, a third repetition period, a fourth repetition period, and a fifth repetition period, and assuming that the destination repetition period is the second repetition period, then “ Obtaining the SC-MCCH control information from the subframe corresponding to the repetition period of the destination repetition period in turn, and parsing "is to first obtain the SC-MCCH control information from the subframe corresponding to the second repetition period. And parsing, if the parsing is successful, stopping, or acquiring SC-MCCH control information from the initial repetition period of the next modification period and parsing; if the SC-MCCH control information corresponding to the second repetition period fails to parse, Acquiring the SC-MCCH control information in the subframe corresponding to the three repetition period, if the parsing is successful, stopping, or acquiring the SC-MCCH control information from the initial repetition period of the next modification period and parsing; if the third repetition period If the corresponding SC-MCCH control information fails to be parsed, the SC-MCCH control information may be obtained from the subframe corresponding to the fourth repetition period, and parsed. If the parsing is successful, the SC-MCCH control information may be stopped, or may be stopped from the beginning of the next modification period. Obtain SC-MCCH control in the repeat cycle If the analysis of the SC-MCCH control information corresponding to the fourth repetition period fails, the SC-MCCH control information may be obtained from the subframe corresponding to the fifth repetition period, and parsed, and if the analysis is successful, the information may be stopped.
