Description

Method, system and terminal for implementing multimedia broadcast multicast service

Technical field

The present invention relates to a multimedia broadcast multicast service (MBMS) implementation technology, and in particular to a method, system and terminal for implementing a multimedia broadcast multicast service.

Background technique

With the rapid development of the Internet and the popularity of large-screen multi-function mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, television broadcasting, video on demand, advertising, online education, interactive games, and the like. This aspect meets the rising business needs of mobile users and brings new business growth points to mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time, and have the characteristics of large data volume, long duration, and delay sensitivity compared with general data services.

In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3GPP, 3rd)

The Generation Partnership Project proposes the MBMS service, which is a technology that transmits data from one data source to multiple targets, realizes the sharing of resources of the network (including the core network and the access network), and improves network resources (especially Utilization of air interface resources). The 3GPP-defined MBMS not only enables plain text low-rate message-like multicast and broadcast, but also enables high-speed multimedia services to 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 3G.

The MBMS system designed in 3GPP Release 9 transmits the MBMS service using the Multimedia Broadcast multicast service Single Frequency Network (MBSFN). The MBSFN transmission mode is to synchronously transmit the same signal (MBMS control signaling and service data) on the same physical resource of multiple intra-frequency cells, so that the UE receiving the MBMS service receives the enhanced signal after multiple cells are superimposed, Improve the signal reception quality of the UE.

The characteristics of MBSFN transmission are as follows: 1) synchronous transmission in the MBSFN area; 2) support for multi-cell MBMS service transmission combining; 3) multicast traffic channel (MTCH, Multicast Traffic Channel) and multicast control channel (MCCH, Multicast Control Channel) at point-to-multipoint ( In pTm) mode, it maps to the multicast channel (MCH); 4) MBSFN synchronization area, MBSFN area, MBSFN transmission, advertisement, reserved cell, all are semi-statically configured by operation and maintenance.

The user equipment (UE, User equipment) of the multiple cells can receive multiple MBMS data with the same content and perform single frequency network (SFN) merging, thereby improving the gain of the received signal. Multiple cells that use the same physical resource and transmit the same MBMS service in MBSFN transmission mode form an MBSFN area.

In the actual long-term evolution (LTE) network, there are several MBSFN services on one MBSFN area. All MBSFN services belonging to the same MBSFN area are called an MBSFN service group, that is, one MBSFN service group. It belongs to only one MBSFN area. An MBSFN area includes multiple cells, and each cell is configured with an identical MBSFN service group. The data channel MTCH of multiple MBSFN services having the same MBSFN area, and the control channel MCCH of the MBSFN service can be multiplexed into one MCH. MCCH and multiple MTCHs of the same MBSFN area, that is, multiple logical channels can be mapped to the same transport channel MCH;

In order to further reduce the power consumption caused by the UE periodically reading the MCCH signaling content, the LTE system simultaneously proposes an MBMS Notification (MBMS Notification) mechanism, and uses physical layer signaling to indicate whether the MCCH information will occur. change. The terminal only needs to monitor the MBMS notification indication. According to the content indicated by the MBMS notification, the terminal decides whether to receive the MCCH information to save power. Each bit corresponds to one MCCH, and the MCCH belongs to a specific MBSFN area. If there is a MBMS service start (session start) process in the MBSFN area, the corresponding bit position will be triggered (=1). The 8 bits are reserved for MBMS notification. Even if the MBSFN area configured in the cell is less than 8, the remaining bits are not used for other purposes (may be assigned an invalid value or 0). In the system broadcast message, the UE is informed which MBSFN area corresponds to which bit, Because an MBSFN area informs the UE of one MCCH corresponding to each of the 8 bits in the PDCCH format 1C for one MCCH, that is, in the system broadcast message.

Notification. Such as:

{bit0, bitl, bit2, ... bit7}=>{MCCH0, MCCH1, MCCH2, ....MCCH7}.

When the UE is interested in the MBMS service of a certain MBSFN area, the UE monitors (monitor)

The MBMS notification indication information, further, the UE may only judge the notification bit corresponding to the MBSFN area of interest. Once the UE detects that the notification bit of interest is set, the UE will read the updated MCCH content when the notification bit corresponds to the MCCH modification period. The UE may only care about the MCCH content change corresponding to the part of the MBSFN area, and determine whether the content of the MCCH corresponding to the MBSFN area is to be changed by the configured notification bit corresponding to the MBSFN area, and according to the modification period and the repetition period of the MCCH. Read the contents of the MCCH.

The PDCCH format 1C carrying the MBMS notification indication information is identified by a special MBMS Temporary Network Identity (M-RNTI), which is located in the common search space of the subframe control domain.

The MBMS notification indication information is carried in the MBSFN subframe. If the MBMS notification indication information has content update, the MBMS notification indication will be sent periodically. Each MCCH has its own modification period, which is related to the modification period of the MCCH with the shortest modification period in the MCCH allocated in the system, and can be repeatedly sent multiple times (specifically 2 or 4 times) in the shortest MCCH modification period. ). If no session of the MBSFN area is about to occur in the next shortest MCCH modification period, that is, if no bit is set in the notification indication information, the notification indication information will be within the shortest MCCH modification period. If not sent, the PDCCH format 1C identified by the M-RNTI is not carried in the common search space of the subframe control domain.

FIG. 1 illustrates a notification transmission situation in the case where there is only one MCCH. In the MBSFN area, there is a service to be initiated in the MCCH modification period n+1. In the MCCH modification period n, the MBMS notification is sent, where the corresponding bit is transmitted. The position starts.

The UE periodically monitors the MBMS notification indication information according to the configured MCCH modification period and the information such as the MBMS notification indication information transmission times and the subframe position. According to MBMS Notification Whether the specific bit is set to trigger the reading of the corresponding MCCH, and obtain the service configuration information (including the service identifier, the service service range, and the corresponding MTCH configuration information) configured in the MCCH, and determine whether the service is a service that is of interest to the user, and determine Whether to receive the service.

In the currently operating system, the operator will inform the user in advance of the service identification, service content, and approximate playback time of the service to be sent by the system, and can be obtained by SMS or by the user to the WAP website of the operator. The program menu.

The user selects the service that he/she wants to receive according to his or her preference, and performs setting on the mobile phone, and the UE records the service identifier of interest configured by the user.

The MBMS service ID is the MBMS Service ID, which is 3 bytes in length. Some services further distinguish the session. You need to add a Session ID with a length of 1 byte.

That is to say, in the program menu, a specific service will be uniquely identified by MBMS Service ID or MBMS service ID + MBMS Session ID.

In the prior art, the terminal first receives the program menu, and then configures the identifier of the specific service according to the program menu. In the receiving process, according to the service identifier in the MCCH signaling, it is determined whether the service that is interested in it determines whether to receive.

Users need to update the program menu in time to get the business situation in the area, and need to be configured, and the configuration process is cumbersome; if for some urgent services, such as traffic accident information, such emergency services are unlikely to be sent a few days ago. The following is described in the program menu. If the operator does not have time to update the program menu (configure the service identifier and service content description) and send it to each UE, the user has no knowledge of the service identifier of these emergency services, and cannot be configured, and the UE is receiving. These important urgent messages are eliminated during the process.

In addition, if the user does not know the identity of the business that he or she is interested in, it is interested in certain types of business, such as sports news, timely traffic information, and so on. For such users, the system cannot explicitly tell the UE which type of service it is before receiving the service data completely. Summary of the invention
