Abstract

Provided are a data processing system, method and apparatus. A base station can generate a session end message; after receiving the session end message, a user equipment needs to further determine whether a session of its own with the base station needs to be ended; at this time, if the parsing of SC-MCCH control information obtained from a starting repetition period of a current modification period fails, then SC-MCCH control information is successively obtained from repetition periods subsequent to the starting repetition period, and same is parsed until the parsing succeeds. Compared to only obtaining SC-MCCH control information from a starting repetition period of a modification period in the art, since the frequency of acquiring and parsing SC-MCCH control information is increased, the success rate of parsing the SC-MCCH control information is improved; thus the SC-MCCH control information can be rapidly parsed, and thus it can be determined whether a user equipment itself needs to end a session with a base station, so that the session can be ended in time.

Background technique

MBMS (Multimedia Broadcast/Multicast Service) is a service introduced in 3GPP Release 6. 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 adopting the SC-PTM scheme, for each cell, there is an SC-MCCH (Single Cell Multicast Control Channel), and a plurality of SC-MTCH service related information (Single Cell Multicast Transport Channel, Single cell multicast traffic channel). The SC-MCCH carries the control information of each SC-MTCH service-related information, and each UE in the cell can obtain the SC-MTCH service-related information corresponding to the corresponding SC-MCCH control information, so that the UE can respond according to the corresponding The SC-MTCH service related information correctly demodulates and decodes data, such as video resources.

The base station periodically sends the SC-MCCH control information, and the SC-MCCH control information may be located in a preset subframe of a Modify Period (MP) and a Repetition Period (RP), such as a start subframe, and a modification. The cycle may include a plurality of repetition periods. As shown in FIG. 1, one modification period MP includes two repetition periods RP, and the SC is successfully parsed when the user does not repeat the start period of the modification period (ie, the first repetition period). - MCCH control information, then the user will acquire the SC-MCCH control information again in the next modification period.

The base station can establish a session with multiple UEs. When the session starts, the base station broadcasts the session start information to each UE. When the UE receives the session start information, and obtains the SC-MCCH control information, it can obtain the corresponding information. When the SC-MTCH service-related information is determined, the session is started. When the SC-MCCH control information that is parsed by the UE does not include the SC-MTCH service-related information corresponding to the UE, the session ends. If the user does not successfully resolve the SC-MCCH control, The information will continue to parse the SC-MCCH control information in the next modification period, so that the session duration is long and the session cannot be ended in time.

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.

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 modification of the SC-MCCH control information. The period, the repetition period of the SC-MCCH control information, and the SC-MCCH control information are located in the position information of the subframe corresponding to the repetition period, and the user can obtain the location information of the SC-MCCH control information through the SIB20 message, and then, from the modification period The SC-MCCH control information is obtained from the location information of the subframe corresponding to the initial repetition period, and the SC-MCCH control information is parsed. When the parsing is successful, the SC-MTCH service corresponding to the user equipment UE is obtained from the SC-MCCH control information. Corresponding information; the SC-MCCH control information may include a correspondence between the MBMS service ID and the SC-MTCH service related information, and 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.

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 SC-MCCH control information generated by the base station does not include the corresponding user equipment UE. The information about the SC-MTCH service is related. When the user equipment UE does not detect the SC-MTCH service related information corresponding to the MBMS service ID in the successfully parsed SC-MCCH control information, the user equipment UE ends the session. When 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. 2, the embodiment of the present application uses a modification period. (Modification Period, MP) includes 2 repetition periods (RP) For example, the solid rectangle is the location 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 SC-including the MBMS service ID corresponding to the user equipment UE. The MTCH service-related information, the SC-MCCH control information in the modification period 3 and the modification period 4 is 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. 2, 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.

Therefore, the embodiment of the present application provides a data processing system. Referring to FIG. 3, it is a schematic structural diagram of a data processing system according to an embodiment of the present disclosure. The data processing system includes: a base station 301 and a user equipment 302, where:

The base station 301 is configured to: when receiving the session end command sent by the core network, generate a session end message, and broadcast the session end message; and periodically send the SC-MCCH control information.

The sending period of the SC-MCCH control information is a modification period, and each of the modification periods includes multiple repetition periods, and the SC-MCCH control information is carried in a subframe corresponding to each repetition period. For the relationship between the modification period and the repetition period, refer to the description of FIG. 2, and details are not described herein again.

The core network includes: MME (Mobility Management Entity)/SGSN (Serving GPRS Support Node) 401, MBMS GW (Multimedia Broadcast Multicast Service Gateway) 402, BM- SC (Broadcast Multicast Service Center, Broadcast/Multicast Service Center) 403.

FIG. 4 is a signaling diagram of a base station broadcasting a session end message to a user equipment UE according to an embodiment of the present application. The detailed steps are as follows:

Step S41: The BM-SC 403 transmits a session end request to each MBMS GW 402 in the cell.

Step S42: Each MBMS GW 402 feeds back a session end response to the BM-SC 403, and transmits a session end request to the MME/SGSN 401.

The MBMS GW 402 passes the session end request to all MME/SGSNs 401 associated with this bearer, and releases the user plane resources with the eNB 404 and the MBMS Bearer Context.

Step S43: The MME/SGSN 401 feeds back the session end response to the MBMS GW 402.

Step S44: The MME/SGSN 401 transmits a session end request to the eNB (evolved NodeB) 404, and the eNB 404 feeds back the session end response to the MME/SGSN 401.

The MME/SGSN 401 sends a session end request to all eNBs 404 associated with the bearer, the eNB 404 feeds back the session end response, and the MME/SGSN 401 releases the MBMS Bearer Context.

Step S45: The eNB 404 sends an IGMPv3 Membership Report to the MME/SGSN 401.

The eNB 404 exits the associated IP multicast group.

Step S46: The eNB 404 generates a session end message and broadcasts it to the user equipment UE 405.

The session end message may be carried by an independent frame, that is, a single signal, or may be carried in a frame in which the SC-MCCH control information is located, that is, in a subframe corresponding to each repetition period of each modification period, that is, the eNB 404. The session end message may be set to the DCI 1C (Downlink Control Information Format 1C) scrambled by the SC-N-RNTI (Single Cell Notification RNTI). Indicates the session end message.

The following describes the structure of the frame where the session end message is located in the embodiment of the present application. The session end message can occupy 1 bit, as shown in FIG. 5(a), the session end message is located in the first bit, and is represented by 1, and can of course be located in other bits, as shown in FIG. 5(b). of course The session end message can be represented by 0, as shown in Figure 5(c).

The LSB (Least Significant Bit) indicates the least significant bit, and the MSB (Most Significant Bit) indicates the most significant bit.

The user equipment 302 is configured to acquire SC-MCCH control information from a subframe corresponding to a start period of a current modification period, and parse the SC-MCCH control information; and when receiving the session sent by the base station Ending the message, and when the SC-MCCH control information obtained from the initial repetition period fails to be parsed, sequentially acquiring the SC-MCCH control information from a subsequent repetition period of the initial repetition period, And parsing until the SC-MCCH control information is successfully parsed.

Assuming that the modification period includes three repetition periods, and is sequentially referred to as a start repetition period, a second repetition period, and a third repetition period, "the SC is sequentially acquired from subsequent repetition periods of the initial repetition period, respectively. - MCCH control information, and parsing until the SC-MCCH control information is successfully parsed" means that the SC-MCCH control information is first acquired 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 parsing fails, acquiring SC- from the subframe corresponding to the third repetition period The MCCH control information may be stopped if the analysis is successful, or the SC-MCCH control information may be acquired and parsed from the initial repetition period 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 is successfully parsed, 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.

As shown in FIG. 5, if the user equipment receives the session end message in the modification period 3, but the SC-MCCH control information obtained in the repetition period 31 is not successfully resolved, the SC-MCCH control can be obtained from the repetition period 32. Information and parsing, if obtained from repeat cycle 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 the data processing system provided by the embodiment of the present application, the base station may generate a session end message. After receiving the session end message, the user equipment needs to further determine whether it is necessary to end the session with the base station. If the SC-MCCH control information obtained in the initial repetition period of the cycle fails to be parsed, the SC-MCCH control information is sequentially obtained from the subsequent repetition period and parsed until the analysis is successful. Compared with the prior art, only when the C-MCCH control information is obtained from the start repetition period of the modification period, since the frequency of acquiring and parsing the SC-MCCH control information is improved, the success rate of analyzing the SC-MCCH is improved, thereby enabling The SC-MCCH control information is quickly parsed, so that it is possible to further determine whether it is necessary to end the session with the base station, so that the session can be ended in time.

In order to improve the success rate of the SC-MCCH control information, the user equipment obtains the SC-MCCH control information from the subframe corresponding to the subsequent repetition period of the initial repetition period, and parses the specific Used for:

The obtained at least one SC-MCCH control information that has failed to be parsed is soft-combined with the currently obtained unresolved SC-MCCH control information to obtain the combined SC-MCCH control information. The combined SC-MCCH control information is parsed.

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, redundancy version The 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 of the SC-MCCH control information in the third repetition period is corresponding to the first repeated cycle SC-MCCH control information received in the previous two times of the buffer. The bits 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.

It can be understood that the user equipment is further configured to: when the SC-MCCH control information obtained in each repetition period in the same modification period fails to be parsed, sequentially obtain the SC-MCCH control information from each repetition period of the next modification period. And parse until the successful SC-MCCH control information is parsed.

After receiving the session end message, the user equipment UE does not represent that the user equipment UE and the base station's session ends, because the base station sends the session end message, which is broadcasted, when the session of a certain user equipment UE ends. The base station broadcasts a session end message, that is, after the user equipment UE receives the session end message, it may indeed be that the user ends the session, or the other user equipment UE needs to end the session. The user equipment may be further configured to: when the SC-MCCH is successfully parsed, determine whether the SC-MCCH service-related information corresponding to the user equipment is included in the SC-MCCH; When the SC-MTCH service related information, it is determined that the session ends.

Optionally, the user equipment is further configured to: when the SC-MCCH control information corresponding to the user equipment is included, still obtain the SC-MCCH control information only from the subframe corresponding to the start of the repetition period of the modification period, And parsing. Therefore, the number of times that the user equipment frequently acquires and parses the SC-MCCH control information is reduced, the power of the user equipment is saved, and the processing speed of the user equipment is provided.

The user equipment is further configured to: when the session end message is not received, when the SC-MCCH control information obtained from the initial repetition period fails to be parsed, the repetition period from the start of the next modification period corresponds to The SC-MCCH control information is obtained in the subframe and parsed.

The embodiment of the present application further provides a data processing method applied to the user equipment in the data processing system, and a data processing method applied to the base station in the data processing system. Please refer to FIG. A signaling diagram between a base station and a user equipment.

Step S61: When receiving the session end instruction sent by the core network, the eNB 404 generates a session end message and broadcasts the session end message.

Step S62: The eNB 404 periodically broadcasts the SC-MCCH control information.

The sending period of the SC-MCCH control information is a modification period, each of the modification periods includes multiple repetition periods, and the SC-MCCH control information is carried in a subframe corresponding to each of the repetition periods.

Step S63: The user equipment UE 405 acquires SC-MCCH control information from the subframe corresponding to the start of the repetition period of the modification period, and parses the SC-MCCH control information.

Step S64: When the user equipment UE 405 receives the session end message sent by the eNB 404, And when the SC-MCCH control information obtained from the initial repetition period fails to be parsed, the SC-MCCH control information is sequentially obtained from the subframe corresponding to the subsequent repetition period of the initial repetition period, and parsed, Until the successful SC-MCCH control information is resolved.
