Description

Method, system and device for transmitting MBMS control signaling scheduling information

With the rapid development of the Internet and the popularity of large-screen multi-function mobile phones, there have been a large number of mobile data multimedia services and various high-bandwidth multimedia services, such as: video conferencing, television broadcasting, video on demand, advertising, online education, interactive games, etc. These multimedia services meet the rising business needs of mobile users on the one hand, and bring new business growth points to mobile operators on the other hand. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity.

In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) proposes Multimedia Broadcast Multicast Service (MBMS), which is a data source to multiple The technology of transmitting data by the target realizes sharing of network resources including the core network and the access network, and improves the utilization of network resources, especially the utilization of air interface resources. The 3GPP-defined MBMS not only enables plain text low-rate message class broadcast and multicast, but also enables high-speed multimedia service broadcast and multicast, providing a variety of rich video, audio and multimedia services, which undoubtedly conforms to future mobile The trend of data development provides a better business prospect for the development of third-generation (3G) mobile communications.

In the Long Term Evolution (LTE) system, the transmission of the MBMS service on the air interface is divided into a dedicated carrier and a hybrid carrier. The main difference between the two transmission modes is: a dedicated carrier mode, where the carrier only carries the MBMS service; Mixed carrier mode, carrier not only The MBMS service also carries non-MBMS services, such as unicast services. In this way, in the process of carrying the MBMS service in the hybrid carrier mode, there are two types of services multiplexing the same carrier. In the process of using the mixed carrier-mounted MBMS service and the non-MBMS service, the two types of services adopt time division multiplexing (TDM). , Time-Division Multiplexing ). In this case, it is very important to let the two types of services do not interfere with each other and play the most important role in the transmission business process.

Control channel signaling.

The broadcast control channel (BCCH, Broadcast Control Channel) carries one or two P-MCCH scheduling configuration information, that is, a P-MCCH may be indicated on the BCCH, and the indicated P-MCCH may be in a single cell mode. It may also be in multi-cell mode; two P-MCCHs may also be indicated on the BCCH, where the indicated P-MCCH is a single cell mode, a multi-cell mode, and the single cell mode is transmitted on the downlink shared channel (DL) -SCH), the multi-cell mode is transmitted on the multicast channel (MCH).

The basic idea of the present invention is to indicate the location of the scheduling configuration information of the MBMS-related control signaling on the BCCH, and to transmit the scheduling configuration information of the MBMS-related control signaling at the indicated location; correspondingly, the terminal determines the MBMS according to the indication on the BCCH. The relevant control signaling schedules the location of the configuration information, and receives scheduling configuration information of the MBMS-related control signaling, and then receives and parses the MBMS-related control signaling itself. The invention has less overhead on the BCCH, and can greatly reduce the range of blind detection of the terminal without losing the flexibility of the indication.

Further, the present invention may first set a radio network temporary identifier of the MBMS service control signaling, and correspondingly, further indicate a location of the radio network temporary identifier of the MBMS service control signaling on the BCCH, and send the MBMS service control signal at the indicated location. The wireless network temporary identification.

Here, the MBMS-related control signaling is multicast control channel signaling or primary multicast control channel signaling; the multicast control channel signaling refers to signaling carried on the MCCH, which is hereinafter referred to as MCCH; The primary multicast control channel signaling refers to the signaling carried on the P-MCCH, which is described below. Shown as P-MCCH.

Specifically, the system may first set a specific Radio Network Temporary Identifier (RNTI) for the MBMS-related control signaling, and record it as MCCH-RNTI. Generally, the temporary identifier of the wireless network is pre-agreed, for example, directly by the protocol, so that the terminal does not need to be notified; of course, it can also be set at the time of use. In this case, the network side needs to notify the terminal of the temporary identifier of the wireless network set by the terminal. . The set MCCH-RNTI is used to identify all MBMS-related control signaling, such as MCCH, P-MCCH, which is recognized by the terminal. The system refers to the network side of the mobile communication system.

The method for transmitting MBMS control signaling scheduling information proposed by the present invention comprises two parts: a method for indicating MBMS control signaling scheduling information, and a method for acquiring MBMS control signaling scheduling information. The following is an example in which the MBMS-related control signaling is a P-MCCH, and the P-MCCH may be a P-MCCH in a multi-cell mode or a P-MCCH in a single-cell mode.

1 is a schematic flowchart of a method for indicating MBMS control signaling scheduling information according to the present invention. As shown in FIG. 1, the method for indicating MBMS control signaling scheduling information includes:

Step 11: indicating the location of the scheduling configuration information carrying the MCCH-RNTI and its corresponding P-MCCH on the BCCH;

Here, the MCCH-RNTI is set by the system in advance for the P-MCCH; the location of the indicated scheduling configuration information of the bearer MCCH-RNTI and its corresponding P-MCCH may be the bearer MCCH-RNTI and its corresponding P-MCCH. The location of the frame in which the scheduling configuration information is located may also be the transmission time in which the scheduling configuration information of the MCCH-RNTI and its corresponding P-MCCH is located. In this step, the system places the indication information on the BCCH for transmission, and the indication information is used to indicate The location of the frame where the scheduling configuration information of the MCCH-RNTI and its corresponding P-MCCH is carried. The system refers to the network side of the mobile communication system; the frame refers to the multicast frame allocated by the system in the MBMS service in the multi-cell mode, and the MBMS service in the single-cell mode in the single-cell mode. The frame of the service.

In this step, the sending time window refers to: sending scheduling configuration information of the MCCH-RNTI and its corresponding P-MCCH in a period of time. For example, on the subframe within 6 ms of the start of the indicated frame (including the indicated frame), the system sends the scheduling configuration information of the MCCH-RNTI and its corresponding P-MCCH once.

For the multi-cell mode, the transmission time window is composed of subframes of a multicast frame, that is, only the time elapsed for the multicast subframe is calculated at the time of counting. For example: Assume that the transmission time window in multi-cell mode is 6 ms. Since each sub-frame length is 1 ms, the transmission time window includes six multicast sub-frames, which are specific to the resource allocation structure shown in FIG. 3, assuming BCCH. The indicated radio frame is #0, that is: the transmission time window starts from the multicast frame #0, and the constituent subframe of the transmission time window is the three multicast sub-frames and the multicast frame in the multicast frame #0# Three multicast sub-frames in 4. Further, in the specific implementation, the length of the transmission time window may be pre-defined, so that it is not necessary to notify the terminal to send the length of the time window, as long as the start frame of the transmission time window is notified.

For the single cell mode, the transmission time window is composed of subframes carrying the single cell mode MBMS service.

Step 12: The system sends scheduling configuration information including the MCCH-RNTI and its corresponding P-MCCH on the agreed resource in the subframe in the indicated location, and sends the P-MCCH in the subframe. information.

In the present invention, for the MBMS service in the multi-cell mode, the system preferentially places the scheduling configuration information of the MCCH-RNTI of the P-MCCH and its P-MCCH on the first multicast subframe in the multicast frame indicated by the BCCH. To reduce the number of blind checks when the terminal receives the MCCH-RNTI.

For the MBMS service in the single-cell mode, the system preferentially places the scheduling configuration information of the MCCH-RNTI of the P-MCCH and its P-MCCH on the first subframe of the MBMS service in the frame of the MBMS service indicated by the BCCH. To reduce the number of blind checks when the terminal receives the MCCH-RNTI. In the present invention, the BCCH can directly indicate the location of the subframe in which the MCCH-RNTI and its corresponding P-MCCH scheduling configuration information is located, that is, the BCCH indicates the MCCH-RNTI and its corresponding P-MCCH scheduling configuration information. The position of the frame is further indicated by the location of the subframe in the frame; or the location information of the subframe in which the MCCH-RNTI and its corresponding P-MCCH scheduling configuration information are directly indicated on the BCCH. Correspondingly, the terminal only needs to detect the MCCH-RNTI in the subframe indicated by the BCCH to obtain the scheduling configuration information of the corresponding P-MCCH, and then instruct to receive the P-MCCH information according to the scheduling configuration information of the P-MCCH.

In the present invention, the intra-subframe agreed resource may be the first three Orthogonal Frequency Division Multiplexing (OFDM) symbols in a unicast subframe, or referred to as a physical downlink control channel (PDCCH, Physical Downlink Control CHannel); may also be the first two OFDM symbols in the multicast subframe, or the third OFDM symbol of the multicast subframe.

2 is a schematic flowchart of a method for obtaining MBMS control signaling scheduling information according to the present invention. As shown in FIG. 2, the method for obtaining MBMS control signaling scheduling information includes:

Step 21: The terminal reads the indication information of the frame location information of the MCCH-RNTI and its corresponding P-MCCH scheduling configuration information on the BCCH and parses the information;

Step 22: After the parsing, the terminal detects the resource in the subframe in the frame in the step 21 to obtain the MCCH-RNTI; and acquires the scheduling configuration information of the P-MCCH corresponding to the MCCH-RNTI;

If the frame indicated by the step 21 is the start position of the transmission time window, the terminal detects on the agreed resource of the subframe constituting the transmission time window according to the pre-agreed transmission time window length until the MCCH-RNTI is obtained, and acquires the MCCH- The scheduling configuration information of the P-MCCH corresponding to the RNTI; Step 23: Receive the P-MCCH information itself and parse the corresponding resource according to the indication of the P-MCCH scheduling configuration information. The implementation of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

3 is a schematic diagram of resource allocation of an MBMS service in a multi-cell mode. In FIG. 3, the horizontal direction is a time axis, the vertical direction is a frequency axis, and 32 radio frames constitute a modification period, and each radio frame includes 10 subframes, each subframe length. For lms. The slash fill portion is a multicast resource allocated by the system to the MBSF area for transmitting MBMS service data. It can be seen that a modification period is divided into eight MBMS radio frames, and there are three multicast subframes in each MBMS radio frame.
