多媒体广播组播业务通知信息的配置方法及装置 Method and device for configuring multimedia broadcast multicast service notification information

技术领域本发明涉及通信领域，具体而言，涉及一种多播广播组播业务TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a multicast broadcast multicast service

( Multimedia Broadcast Multicast Service, 简称为 MBMS ) 通知信息的配置方法及装置。背景技术随着网络（ Internet ) 的迅猛发展和大屏幕多功能手机的普及，出现了大量移动数据多媒体业务和各种高带宽多媒体业务，例如，视频会议、电视广播、视频点播、广告、网上教育、互动游戏等，这一方面满足了移动用户不断上升的业务需求，同时也为移动运营商带来新的业务增长点。这些移动数据多媒体业务要求多个用户能够同时接收相同数据，与一般的数据业务相比，具有数据量大、持续时间长、时延敏感等特点。为了有效地利用移动网络资源，第三代合作伙伴计划（3rd Generation Partnership Project, 简称为 3GPP )提出了 MBMS业务，该业务是一种从一个数据源向多个目标传送数据的技术，实现了网络（包括核心网和接入网）资源的共享，提高了网络资源（尤其是空中接口资源）的利用率。 3GPP 定义的 MBMS 不仅能够实现纯文本低速率的消息类组播和广播，而且还能够实现高速多媒体业务的广播和组播，提供多种丰富的视频、音频和多媒体业务，这无疑顺应了未来移动数据发展的趋势，为 3G的发展提供了更好的业务前景。 (Multimedia Broadcast Multicast Service, abbreviated as MBMS) Configuration method and device for notification information. BACKGROUND 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, for example, video conferencing, television broadcasting, video on demand, advertising, online education. , interactive games, etc., this aspect meets the rising business needs of mobile users, but also brings new business growth points for 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) proposed the MBMS service, which is a technology that transmits data from one data source to multiple targets, and implements the network. The sharing of resources (including the core network and the access network) improves the utilization of network resources (especially 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.

MBMS业务的特点是业务的数据量大，终端接收时持续时间长，平均数据率恒定。上述特点决定了 MBMS 业务的调度，控制信令配置都是半静态配置的，即 MBMS业务的调度信息，多播控制信道（ Multicast Control Channel, 简称为 MCCH )信息都是 "长期" 保持不变的，这样在 MCCH信息的发送周期到来时，网络侧发送一个不变的信息（连续发送是因为随时都可能有新用户接入；)。目前为了帮助终端在接收 MCCH信息时省电，提出了 MCCH信息周期性发送。具体为 MCCH信息有重复周期、修改周期。修改周期一般为重复周期的整数倍，一个修改周期内包含多个重复周期，修改周期内的每个重复周期到来时，网络侧都发送一次 MCCH信息，每次发送的 MCCH信息都是相同的，只有在修改周期到来时才允许修改 MCCH信息。这样可以减少终端减少接收 MCCH信息的次数，从而实现一定程度的省电。另一方面，通过引入 MBMS 通知机制帮助终端避免接收没有发生的更新的 MCCH信息。 MBMS通知机制同样可以实现 MCCH信息的 4爹改周期的功能，甚至可以比修改周期做的更好。相关技术中， MCCH信息可以通过下述处理进行配置： The MBMS service is characterized by a large amount of data in the service, a long duration of reception by the terminal, and a constant average data rate. The above features determine the scheduling of the MBMS service. The control signaling configuration is semi-statically configured, that is, the scheduling information of the MBMS service. The multicast control channel (MCCH) information is "long-term" unchanged. Thus, when the transmission period of the MCCH information arrives, the network side sends a constant message (continuous transmission is because new users may be accessed at any time;). Currently, in order to help the terminal save power when receiving MCCH information, it is proposed that the MCCH information is periodically transmitted. Specifically, the MCCH information has a repetition period and a modification period. The modification period is generally an integer multiple of the repetition period. A modification period includes multiple repetition periods. When each repetition period in the modification period comes, the network side sends MCCH information once, and each time the MCCH information is sent. They are all the same, and the MCCH information is allowed to be modified only when the modification period comes. This can reduce the number of times the terminal reduces the number of MCCH information received, thereby achieving a certain degree of power saving. On the other hand, the introduction of the MBMS notification mechanism helps the terminal avoid receiving MCCH information of updates that have not occurred. The MBMS notification mechanism can also implement the function of the 4 tampering period of the MCCH information, and can even do better than the modification period. In the related art, the MCCH information can be configured by the following processing:

( 1 ) 设置一个 MCCH 4爹改周期（Will have an MCCH modification period )。 (1) Set a MCCH 4 tampering period (Will have an MCCH modification period).

( 2 )设置一个通知机制 ( We will have a notification mechanism )„ ( 3 ) 通知机制用于会话开始，正在接收月艮务的用户在每个 4爹改周期读取 MCCH( Notification mechanism will be used for session starts. UE receiving a service will have to read the MCCH every modification period )。 (2) Set a notification mechanism (We will have a notification mechanism) „ (3) The notification mechanism is used for the session start, and the user who is receiving the monthly service reads the MCCH in each of the 4 tampering cycles (Notification mechanism will be used for Session starts. UE receiving a service will have to read the MCCH every modification period ).

( 4 ) 空闲用户只需要在每个寻呼时机或另外的唤醒时机来检查通知消息 ( UE in IDLE only needs to check the notification during its paging occasion or does the UE wakeup additionally ( FFS ) )。 (4) The idle user only needs to check the notification message (UE in IDLE only needs to check the notification during its paging occasion or does the UE wakeup Additionally (FSS)).

( 5 )如果用户接收到通知消息，在下一个 MCCH修改周期时读取 MCCH 信息 ( If the UE sees the notification, it will acquire the MCCH after the next MCCH modification period boundary )。 (5) If the user receives the notification message, the MCCH after the next MCCH modification period boundary is read at the next MCCH modification period.

( 6 ) 物理下行控制信道（Physical Downlink Control CHannel, 简称为 PDCCH ) 使用 MBMS 专用无线网络临时标 i只 ( MBMS Radio Network Temporary Identifier, 简称为 M-RNTI )为通知消息（ PDCCH with new MBMS Specific M-RNTI is used for notification )。从以上描述可以看出： MBMS通知机制被引入的同时引入了 MCCH信息修改周期。但是，对于 MBMS 通知信息进行了一些限制，例如， MBMS 通知机制仅用于业务会话开始（ session start )之前，当接收端正在接收 MBMS 业务时，应该保持每个 MCCH 信息爹改周期读取 MCCH 信息。并且引入 M-RNTI为了帮助接收端在 PDCCH中接收通知信息。如果定义的 MBMS通知信息是用来指示即将到来的 MCCH信息修改周期中 MCCH信息与上一个修改周期的 MCCH信息相比，是否发生了更新，使用 1比特信息表示即可实现（该比特取值为 1 , 表示更新，取值为 0, 表示未更新），但是，这样做可能由于 MBMS通知信息指示不清，而给造成更多的接收端接收解析 MCCH 信息。下面举例说明。例^口， £设某一多播广播单频网络（ Multimedia Broadcast multicast service Single Frequency Network, 简称为 MBSFN ) 区 i或内有 100个 MBMS业务，每个业务在不同的时刻会话开始（ session start ), 在不同的时刻会话结束 ( session stop ), 或者在不同时刻有 MBMS业务数据更新（即， MBSFN子帧配置发生更新）。这些都是可以引起 MCCH信息发生更新的因素。当然可能还有其他的原因，由于目前 MCCH信息中明确包含上述信息，其他信息有待 MCCH信息本身的进一步完善。如果 MBMS通知信息内容仅为 1比特时，会带来下面的问题，例如，当某一 MBMS业务由于会话结束，而引起 MCCH 信息发生更新，这样其实只对正在接收 MBMS 业务的终端有效，但是对于没有接收，正在准备接收自己感兴趣的业务的接收端是无效的，这类终端只对于会话开始引起的 MCCH信息更新感兴趣，但是如果仅使用 1比特，会造成所有终端都要重新读取 MCCH信息。 MBMS通知信息和 MCCH信息相比较，数据量很大，终端读取 MCCH信息是比较费电的。发明内容针对相关技术可能由于 MBMS 通知信息指示不清而造成更多的接收端接收解析 MCCH信息的问题而提出本发明，为此，本发明的主要目的在于提供一种

(6) The physical downlink control channel (Physical Downlink Control CHannel, hereinafter referred to as PDCCH) uses the MBMS Radio Network Temporary Identifier (MB-RNTI) as the notification message (PDCCH with new MBMS Specific M- RNTI is used for notification ). It can be seen from the above description that the MCMS information modification period is introduced while the MBMS notification mechanism is introduced. However, there are some restrictions on the MBMS notification information. For example, the MBMS notification mechanism is only used before the session start. When the receiver is receiving the MBMS service, it should keep reading the MCCH information for each MCCH information tampering period. . And the M-RNTI is introduced to help the receiving end receive the notification information in the PDCCH. If the defined MBMS notification information is used to indicate whether the MCCH information in the upcoming MCCH information modification period is compared with the MCCH information of the previous modification period, whether the update occurs, the 1-bit information representation is used. Now (the value of this bit is 1, indicating update, the value is 0, indicating that it is not updated). However, this may cause more receivers to receive the parsed MCCH information because the MBMS notification information indicates unclear. The following is an example. For example, a Multimedia Broadcast multicast service Single Frequency Network (MBSFN) area i or 100 MBMS services are set up, and each service starts at a different time (session start). End of session at different times (session stop), or MBMS service data update at different times (ie, MBSFN subframe configuration is updated). These are all factors that can cause MCCH information to be updated. Of course, there may be other reasons. Since the MCCH information currently contains the above information, the other information needs to be further improved by the MCCH information itself. If the MBMS notification information content is only 1 bit, the following problems may occur, for example, when an MBMS service is terminated due to the end of the session, the MCCH information is updated, so that it is only valid for the terminal that is receiving the MBMS service, but If there is no reception, the receiving end that is preparing to receive the service of interest is invalid. Such terminal is only interested in the MCCH information update caused by the start of the session, but if only 1 bit is used, all terminals will re-read the MCCH. information. Compared with the MCCH information, the MBMS notification information has a large amount of data, and the terminal reads the MCCH information to be relatively expensive.

Process at the receiving end: The receiving end (the receiving end interested in the MBMS service) listens to the notification message 1 before receiving the MBMS service, and monitors the result if the MCCH is indicated. The information is updated, and the parsed MCCH information is received at the next upcoming MCCH modification period. Otherwise, the MCCH information is no longer received at the next upcoming MCCH modification period. For the receiving end that is already receiving the MBMS service, only the notification message 2 needs to be monitored. If the notification message 2 informs the receiving end that the upcoming MCCH information is updated (the update includes: the session start, the update, the end, etc.) ), the MCCH information is re-received, otherwise, the MCCH information is not re-received. Embodiment 4 The notification information 1 transmitted by the transmitting end includes only the session start indication information, and the notification information 2 includes indication information indicating whether each of the plurality of different MCCH information has been updated.

The terminal can know that if the MCCH information is updated, it can be seen exactly what causes the MCCH update. Then, the receiving end determines whether it needs to update the MCCH information according to its own needs. If it needs to be updated, it receives the parsing MCCH information at the next upcoming MCCH modification period. Otherwise, the MCCH information is no longer received at the next upcoming MCCH 4 tampering period. Secondly, for the receiving end that is receiving the MBMS, the following procedure can also be used, and the MBMS notification message 2 is no longer received, and the MCCH information is read when each MCCH 4 tampering period comes. Embodiment 7 The embodiments in the present application and the features in the embodiments may be combined with each other without conflict. An example will be given below. For example, the combination of Embodiment 5 or Embodiment 6 and Embodiment 4, the MBMS notification information in Embodiments 5 and 6 is independent of the MCCH, and the MBMS notification message in Embodiment 4 is related to the MCCH, so that it can be combined.
