Description

资源配置参数的指示和更新方法、终端及基站技术领域本发明涉及通信领域，具体而言，涉及一种资源配置参数的指示和更新方法、终端及基站。背景技术多播广播业务 ( Multicast Broadcast Service, 简称为 MBS ) 是从一个数据发送源（例如，基站）向多个目标终端传送数据，能够实现网络（包括：核心网络和接入网络）资源的共享，提高网络资源、尤其是空中接口资源的利用率。随着互联网的普及和多媒体技术的发展，多媒体共享业务的应用越来越广，同时，业务的数据量也越来越大，这样，如何高效地进行 MBS 传输对于下一代移动通信***来说也变得尤为重要。下一代移动通信***可以是能够提供更大的带宽的多载波***，承载 MBS的一种方式是独立载波或专用载波方式，即 MBS独占某个载波上的所有时频资源；另一种方式是混合载波或共享载波方式，即 MBS 与单播业务以时分复用或频分复用的方式共享载波上的时频资源。在相关技术中， *** 的帧结构由超帧、帧、子帧构成，其中，一个超帧包含若千个无线帧，一个无线帧中包含若千个子帧。当多播广播业务与单播业务进行频分复用时，多播广播业务可以占用一个载波中全部或部分子帧上的部分频率资源。网络侧的多播广播业务调度器可以根据当前多播广播业务量的需求为一个或多个多播广播区域的多播广播业务在某个载波上预留相应的资源，具体方式为：在一个多播广播业务调度周期内，为每个多播广播业务区域在承载多播广播业务的载波上划分一定的带宽，在时域上则根据业务量的需求预留一个调度周期内的所有子帧或部分子帧。对于小区内的单播业务用户而言，该载波上的剩余资源则由控制站调度给单播业务使用，从而实现单播与多播广播业务的频分复用。控制站内的多播广播业务用户需要获得多播广播业务的调度信息以便进一步故逻辑资源的映射，以及获取具体的业务突发的发送位置。而单播业务用户也需要获取此调度信息，以便获得多播广播业务资源区域的位置，从而准确获知单播业务的资源区域，进一步上报该资源区域的信道状况，更好地应用多天线技术等。因此，多播广播业务的调度信息需要通过***广播消息进行发送，以保证包括接收单播业务的终端在内的所有终端都可以接收。现有技术中，控制站周期性地广播***配置描述消息（ AAI_SCD )给所有移动终端，在此消息中包含有多播广播业务的调度信息，例如，帧分配指示信息，子帧内各个多播广播业务区域及单播业务区域的频域划分指示信息，多播广播业务的调度周期信息等。在基站发送的 AAI_SCD 消息中包含有一个参数更新的计数值（ change count ) 以表示此消息中的参数发生了更新。由于 AAI SCD消息中还包括有非多播广播业务相关的***配置参数，此更新计数值无法明确表示多播广播业务资源配置参数当前是否发生了更新，导致多播广播业务终端进行不必要的接收及更新操作。另外，由于控制站周期性地广播***配置描述消息，处于连接状态The present invention relates to the field of communications, and in particular to a method and an update method for a resource configuration parameter, a terminal, and a base station. A multicast broadcast service (MBS) transmits data from a data transmission source (for example, a base station) to multiple target terminals, and can share resources of a network (including a core network and an access network). Improve the utilization of network resources, especially air interface resources. With the popularity of the Internet and the development of multimedia technologies, the application of multimedia sharing services is becoming wider and wider, and at the same time, the amount of data in services is increasing. How to efficiently perform MBS transmission for next-generation mobile communication systems It becomes especially important. The next-generation mobile communication system may be a multi-carrier system capable of providing a larger bandwidth. One way of carrying the MBS is the independent carrier or the dedicated carrier mode, that is, the MBS monopolizes all time-frequency resources on a certain carrier; The hybrid carrier or the shared carrier mode, that is, the MBS and the unicast service share the time-frequency resources on the carrier in a time division multiplexing or a frequency division multiplexing manner. In the related art, the frame structure of the system is composed of a superframe, a frame, and a subframe, wherein one superframe includes thousands of radio frames, and one radio frame includes if there are thousands of subframes. When the multicast broadcast service performs frequency division multiplexing with the unicast service, the multicast broadcast service may occupy part of the frequency resources on all or part of the subframes of one carrier. The multicast broadcast service scheduler on the network side can reserve corresponding resources on a certain carrier for the multicast broadcast service of one or more multicast broadcast areas according to the requirements of the current multicast broadcast traffic. The specific manner is as follows: During the multicast broadcast service scheduling period, each multicast broadcast service area is allocated a certain bandwidth on the carrier carrying the multicast broadcast service, and in the time domain, all the subframes in one scheduling period are reserved according to the demand of the traffic. Or part of a sub-frame. For the unicast service users in the cell, the remaining resources on the carrier are scheduled by the control station to be used by the unicast service, thereby implementing frequency division multiplexing of the unicast and multicast broadcast services. The multicast broadcast service user in the control station needs to obtain the scheduling information of the multicast broadcast service to further map the logical resources and obtain the transmission location of the specific service burst. The unicast service user also needs to obtain the scheduling information, so as to obtain the location of the multicast broadcast service resource area, thereby The resource area of the unicast service is accurately learned, the channel condition of the resource area is further reported, and the multi-antenna technology is better applied. Therefore, the scheduling information of the multicast broadcast service needs to be sent through the system broadcast message to ensure that all terminals including the terminal receiving the unicast service can receive. In the prior art, the control station periodically broadcasts a system configuration description message (AAI_SCD) to all mobile terminals, where the message includes scheduling information of the multicast broadcast service, for example, frame allocation indication information, and each multicast in the subframe. Frequency domain division indication information of the broadcast service area and the unicast service area, scheduling period information of the multicast broadcast service, and the like. The AAI_SCD message sent by the base station contains a parameter update count value (change count) to indicate that the parameters in this message have been updated. Since the AAI SCD message also includes system configuration parameters related to the non-multicast broadcast service, the update count value cannot clearly indicate whether the multicast broadcast service resource configuration parameter is currently updated, and the multicast broadcast service terminal performs unnecessary reception. And update operations. In addition, since the control station periodically broadcasts the system configuration description message, it is in the connected state.

( connected state )的所有终端周期性地获取并更新该广播消息，对于在混合载波上接收单播业务的终端可以及时获得多播广播业务相关的资源配置信息，从而确定该载波上单播业务的资源区域，以便上报单播业务资源的信道条件，保证多天线技术的应用。对于接收多播广播业务的终端，则需要分两种情况来考虑。一种情况是：该终端以载波聚合 ( carrier aggregation ) 的方式工作，则可以及时获得多播广播业务相关的资源配置信息更新，从而进一步执行资源映射操作，解码多播广播业务控制信息后正确接收多播广播业务。另一种情况是：该终端以载波切换 ( carrier switching ) 的方式工作，当该终端在主载波上接收单播业务，在辅载波上接收多播广播业务（即多播广播业务所在的载波与该终端的主载波不同，多播广播业务所在的载波为其辅载波）时，现有技术中由于终端在主载波和辅载波之间进行切换，这样当终端工作在主载波时，则无法保证该终端能及时获得辅载波上的多播广播业务相关的资源配置信息更新。此外，对于处于睡眠（Sleep )模式或空闲（Idle ) 状态的以载波切换方式工作的接收多播广播业务的终端，也无法及时获取在^载多播广播业务的载波上的多播广播业务的相关资源配置信息以进行更新，导致无法继续正常接收多播广播业务。另外，当多播广播业务的资源配置信息发生变化时，由于携带此信息的 ***配置描述消息 AAI_SCD可能是在一个多播广播业务的调度周期内的某个时刻发送，通常基站启用 AAI_SCD 消息中的参数的时间与多播广播业务的调度周期没有直接的关系，如果 AAI_SCD 消息中与多播广播业务相关的参数发生更新时，若此参数的更新生效时间与多播广播业务的调度周期无关，则将会影响基站对于多播广播业务的发送及终端的接收。另外，若终端接收到 AAI_SCD消息后，按照该 AAI_SCD消息更新多播广播业务的资源配置信息的时间可能是在某个调度周期内的某个时刻，而此时网络侧的多播广播业务的发送仍然是按照更新前的资源配置信息进行发送，因此，终端根据该更新后的多播广播业务的资源配置信息无法正常接收解码相应资源上的业务数据。发明内容本发明的主要目的在于提供一种资源配置参数的指示方法、 MBS资源配置参数的更新方法、终端及基站，以至少解决上述问题。居本发明的一个方面，提供了一种资源配置参数的指示方法，包括：基站发送多播广播业务 MBS 资源配置参数的更新指示信息，其中，该更新指示信息用于指示基站的 MBS资源配置参数是否发生更新。优选地，该方法还包括：终端解析出接收到的更新指示信息的指示为更新 MBS资源配置参数；终端以来自基站的 MBS资源配置参数更新本地保存的

4是才艮据本发明另一种实施例的 MBS资源配置参数的更新方法的流程图；以及图 5是根据本发明实施例的终端和基站的结构框图。具体实施方式下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。在无线通信***中，由于 MBS 可以与单播业务以时分复用或频分复用的方式共享载波上的时频资源，因此，基站需要将 MBS 资源配置参数通知给终端（包括接收 MBS 业务和单播业务的终端），以使终端能够正常接收 MBS数据或者单播业务数据，并且当基站侧所使用的 MBS资源配置参数发生变化时也同样需要将更新后的 MBS 资源配置参数通知给终端。本实施例可以在此无线通信***中实现。图 1是居本发明一种实施例的资源配置参数的指示方法的流程图，如图 1所示，该流程包括以下步骤：步骤 S 102 , 基站发送 MBS资源配置参数的更新指示信息，其中，该更新指示信息用于指示基站的 MBS资源配置参数是否发生更新。例如，基站通过在多播广播业务配置消息（ AAI_E-MBS_CFG ) 中携带多播广播业务资源配置信息的更新指示信息，或者在多播广播业务资源映射消息（ AAI_E-MBS_MAP ) 中携带多播广播业务资源配置信息的更新指示信息发送给终端。相关技术中在基站发送的 AAI_SCD 消息中的参数更新计数值用于指示 AAI SCD消息中的所有参数 (包括有多播广播业务和非 MBS相关的***配置参数）是否发生改变，然而终端根据该更新计数值无法明确获知 MBS 资源配置参数当前是否发生了更新，导致多播广播业务终端进行不必要的接收及更新操作。而本实施例中，基站通过发送用于指示 MBS 资源配置参数是否发生改变的更新指示信息，从而使得终端能够及时获取更新的 MBS 资源配置参数，以及避免了终端对于 MBS的不必要接收及更新操作。优选地，在上述的方法中，还包括：步骤 S 104, 该终端解析出接收到的该更新指示信息的指示为更新 MBS资源配置参数；例如，处于任意状态的接收多播广播业务的终端接收解码 AAI E-MBS CFG消息或者 AAI E-MBS MAP 消息，并判断 jt匕消息中的更新指示信息是否指示为更新，在指示为更新时终端才会在相应的载波上接收解码更新的 AAI_SCD 消息，从而更新多播广播业务的资源配置信息，若指示为不更新时终端可以不接收下一个 AAI_SCD消息。步骤 S 106, 该终端以来自基站的 MBS 资源配置参数更新本地保存的 MBS资源配置参数。例如，当确定 AAI_E-MBS_CFG消息或者 AAI_E-MBS_MAP消息中携带的更新指示信息的指示为更新 MBS 资源配置参数时，认为来自基站的 AAI SCD中携带的 MBS资源配置参数为更新的 MBS资源配置参数，因此，解码更新的 AAI_SCD消息，并更新本地的 MBS资源配置参数，以居该更新后的 MBS资源配置参数进行 MBS数据的接收。其中，上述的 MBS资源配置参数还可以携带在除携带上述更新指示信息的消息以外的其他广播消息中，其中，终端可以在接收 MBS的载波上接收来自基站的 MBS资源配置参数。相关技术中处于载波切换工作方式的连接状态终端或者处于睡眠模式或空闲状态下的终端无法及时获取相应载波上的多播广播业务资源配置信息，导致多播广播业务无法正常接收。本实施例通过向接收多播广播业务的终端发送更新指示信息以指示***配置描述消息中的 MBS 资源配置参数是否更新，使处于任意工作方式的任意状态的终端都能够及时地获得更新的 MBS 资源配置参数，从而使得终端能够正常接收 MBS数据。优选地，步骤 S 102中的 MBS资源配置参数的更新指示信息携带在 MBS 配置消息中，用于指示基站的 MBS资源配置参数是否在所述 MBS配置消息当前的发送或生命周期内发生更新。即当***配置描述消息（ AAI_SCD ) 中的 MBS资源配置参数将在 AAI_E-MBS_CFG消息的当前发送或生命（修改）周期内发生更新（即基站将要使用另一种 MBS 资源配置参数时）时，基站通过在 AAI_E-MBS_CFG中携带 MBS资源配置参数的更新指示信息。具体地，参见表 1 , 该更新指示信息可以是一个更新指示比特（update indicator ), 表示针对上一个 AAI_E-MBS_CFG发送或生命爹改）周期内， AAI_SCD 消息中的 MBS资源配置参数是否发生变化的指示；参见表 3 , 该更新指示信息还可以包括一个更新计数器（ change count ),指示 AAI_SCD消息中的 MBS 资源配置参数的更新计数。参见表 2 , 基站还可以在 AAI_E-MBS_CFG消息中携带更新的 AAI_SCD消息的发送时间信息（包括发送位置或偏置等），如：超帧周期、和 /或超帧偏移、和 /或帧号或帧偏移、和 /或子帧号或子帧偏移。这样，当在 AAI_E-MBS_CFG消息的发送或生命周期内发送多个 AAI_SCD 消息时，终端可以在该发送时间信息所指示的时间去接收 AAI_SCD 消息，即可以获知更新的 AAI_SCD 消息是哪一个，可以正确接收更新后的 AAI SCD消息。表 1 All the terminals (connected state) periodically acquire and update the broadcast message, and the terminal that receives the unicast service on the hybrid carrier can obtain the resource configuration information related to the multicast broadcast service in time, thereby determining the unicast service on the carrier. The resource area is used to report the channel conditions of the unicast service resources to ensure the application of the multi-antenna technology. For a terminal that receives a multicast broadcast service, it needs to be considered in two cases. In one case, if the terminal works in a carrier aggregation manner, the resource configuration information related to the multicast broadcast service can be updated in time to further perform the resource mapping operation, and the multicast broadcast service control information is decoded and correctly received. Multicast broadcast service. In another case, the terminal operates in a carrier switching manner. When the terminal receives the unicast service on the primary carrier, the terminal receives the multicast broadcast service on the secondary carrier (that is, the carrier where the multicast broadcast service is located) When the primary carrier of the terminal is different, and the carrier where the multicast broadcast service is located is its secondary carrier, the terminal switches between the primary carrier and the secondary carrier in the prior art, so that when the terminal works on the primary carrier, it cannot be guaranteed. The terminal can obtain the resource configuration information update related to the multicast broadcast service on the secondary carrier in time. In addition, the terminal receiving the multicast broadcast service operating in the carrier switching mode in the sleep mode or the idle state cannot acquire the multicast broadcast service on the carrier of the multicast broadcast service in time. The related resource configuration information is updated to cause the multicast broadcast service to continue to be received normally. In addition, when the resource configuration information of the multicast broadcast service changes, the system configuration description message AAI_SCD carrying the information may be sent at a certain time in a scheduling period of a multicast broadcast service, and the base station usually activates the AAI_SCD message. The time of the parameter is not directly related to the scheduling period of the multicast broadcast service. If the parameters related to the multicast broadcast service in the AAI_SCD message are updated, if the update effective time of this parameter is independent of the scheduling period of the multicast broadcast service, This will affect the base station's transmission of the multicast broadcast service and the reception of the terminal. In addition, if the terminal receives the AAI_SCD message, the time for updating the resource configuration information of the multicast broadcast service according to the AAI_SCD message may be some time in a certain scheduling period, and at this time, the multicast service of the network side is sent. The data is still sent according to the resource configuration information before the update. Therefore, the terminal cannot receive and decode the service data on the corresponding resource according to the resource configuration information of the updated multicast broadcast service.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In the wireless communication system, since the MBS can share the time-frequency resources on the carrier in a time division multiplexing or frequency division multiplexing manner with the unicast service, the base station needs to notify the terminal of the MBS resource configuration parameters (including receiving the MBS service and The terminal of the unicast service is configured to enable the terminal to receive the MBS data or the unicast service data normally, and also notify the terminal of the updated MBS resource configuration parameter when the MBS resource configuration parameter used by the base station side changes. This embodiment can be implemented in this wireless communication system. 1 is a flowchart of a method for indicating a resource configuration parameter according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps: Step S102: A base station sends an update indication information of an MBS resource configuration parameter, where The update indication information is used to indicate whether the MBS resource configuration parameter of the base station is updated. For example, the base station carries the update indication information of the multicast broadcast service resource configuration information in the multicast broadcast service configuration message (AAI_E-MBS_CFG), or maps the multicast service resource in the multicast broadcast service. The update indication information carrying the multicast broadcast service resource configuration information in the message (AAI_E-MBS_MAP) is sent to the terminal. The parameter update count value in the AAI_SCD message sent by the base station in the related art is used to indicate whether all parameters in the AAI SCD message (including the multicast broadcast service and the non-MBS related system configuration parameter) are changed, but the terminal according to the update The count value cannot clearly know whether the MBS resource configuration parameter is currently updated, which causes the multicast broadcast service terminal to perform unnecessary receiving and updating operations. In this embodiment, the base station sends the update indication information indicating whether the MBS resource configuration parameter is changed, so that the terminal can obtain the updated MBS resource configuration parameter in time, and avoid unnecessary reception and update operations of the terminal for the MBS. . Preferably, in the foregoing method, the method further includes: Step S104, the terminal parses the received indication of the update indication information to update the MBS resource configuration parameter; for example, receiving the terminal receiving the multicast broadcast service in an arbitrary state Decoding an AAI E-MBS CFG message or an AAI E-MBS MAP message, and determining whether the update indication information in the jt匕 message indicates an update, and the terminal receives the decoded updated AAI_SCD message on the corresponding carrier when the indication is an update, Thereby, the resource configuration information of the multicast broadcast service is updated, and if the indication is not updated, the terminal may not receive the next AAI_SCD message. Step S106: The terminal updates the locally saved MBS resource configuration parameter with the MBS resource configuration parameter from the base station. For example, when it is determined that the indication of the update indication information carried in the AAI_E-MBS_CFG message or the AAI_E-MBS_MAP message is the update MBS resource configuration parameter, the MBS resource configuration parameter carried in the AAI SCD from the base station is considered to be the updated MBS resource configuration parameter, Therefore, the updated AAI_SCD message is decoded, and the local MBS resource configuration parameter is updated to receive the MBS data in the updated MBS resource configuration parameter. The foregoing MBS resource configuration parameter may also be carried in a broadcast message other than the message carrying the update indication information, where the terminal may receive the MBS resource configuration parameter from the base station on the carrier that receives the MBS. In the related art, the connection state terminal in the carrier switching mode or the terminal in the sleep mode or the idle state cannot obtain the multicast broadcast service resource configuration information on the corresponding carrier in time, and the multicast broadcast service cannot be normally received. In this embodiment, the update indication information is sent to the terminal that receives the multicast broadcast service to indicate whether the MBS resource configuration parameter in the system configuration description message is more Newly, the terminal in any state in any working mode can obtain the updated MBS resource configuration parameter in time, so that the terminal can receive the MBS data normally. Preferably, the update indication information of the MBS resource configuration parameter in the step S102 is carried in the MBS configuration message, and is used to indicate whether the MBS resource configuration parameter of the base station is updated during the current transmission or lifetime of the MBS configuration message. That is, when the MBS resource configuration parameter in the system configuration description message (AAI_SCD) will be updated during the current transmission or lifetime (modification) period of the AAI_E-MBS_CFG message (ie, the base station is going to use another MBS resource configuration parameter), the base station The update indication information of the MBS resource configuration parameter is carried in the AAI_E-MBS_CFG. Specifically, referring to Table 1, the update indication information may be an update indicator indicating whether the MBS resource configuration parameter in the AAI_SCD message changes during the previous AAI_E-MBS_CFG transmission or life tampering period. Instructed; see Table 3, the update indication information may also include an update counter indicating the update count of the MBS resource configuration parameters in the AAI_SCD message. Referring to Table 2, the base station may also carry the transmission time information (including the transmission position or offset, etc.) of the updated AAI_SCD message in the AAI_E-MBS_CFG message, such as: superframe period, and/or superframe offset, and/or frame. Number or frame offset, and/or subframe number or subframe offset. In this way, when multiple AAI_SCD messages are sent during the transmission or lifetime of the AAI_E-MBS_CFG message, the terminal can receive the AAI_SCD message at the time indicated by the transmission time information, that is, it can know which one of the updated AAI_SCD messages is correct. Receive updated AAI SCD messages. Table 1

As shown in FIG. 2, step S104 includes: receiving, by a terminal in any state, a multicast broadcast service, receiving a decoded AAI E-MBS_CFG message in a periodic manner, when the multicast broadcast service resource configuration information update indication bit in the message indicates " When the update time or update count value changes, step S106 is performed; step S106 includes: the terminal in the connection state of the carrier aggregation working mode receives the decoding update on the carrier where the MBS is located at the time of sending the AAI SCD message. AAI_SCD message to update the MBS resource configuration parameters. Alternatively, the terminal in the connected state of the carrier switching mode (the carrier where the MBS is located is the secondary carrier of the terminal), before the updated AAI_SCD message is sent, if it works on the primary carrier, perform carrier switching, and switch to the corresponding The carrier of the multicast broadcast service (ie, the secondary carrier of the terminal) receives the decoded AAI_SCD message, and updates the local MBS resource configuration parameter; if it does not work on the primary carrier, directly works at the current The AAI_SCD message that decodes the update is received on the carrier where the multicast broadcast service is located. Alternatively, the terminal in the sleep or idle state receives the decoded updated AAI_SCD message on the carrier currently receiving the multicast broadcast service, and updates the local MBS resource configuration parameter. The above preferred embodiment provides a specific implementation manner for the terminal to update the locally saved MBS resource configuration parameter according to the update indication information sent by the base station in the wireless communication system. With the above preferred embodiment, the terminal in the connected state of the carrier switching mode is configured to receive the secondary carrier when the carrier where the MBS is located is the secondary carrier of the terminal (ie, the primary carrier is different from the carrier where the MBS is located). The update indication information in the AAI_E-MBS_CFG message is used to learn that the MBS resource configuration parameter of the base station side is to be updated, and before receiving the AAI_SCD message carrying the updated MBS resource configuration parameter, switch to the carrier where the MBS is located and receive the AAI_SCD message. To update the MBS resource configuration parameters. Similarly, the terminal in the sleep or idle state can also know that the MBS resource configuration parameter of the base station side is to be updated, and the AAI_SCD message carrying the updated MBS resource configuration parameter is received in time to update the MBS resource configuration parameter. Preferably, the update indication information of the MBS resource configuration parameter in the step S102 is carried in the MBS resource mapping message, and is used to indicate whether the MBS resource configuration parameter of the base station is updated in the current MBS scheduling period. That is, when the MBS resource configuration parameter in the AAI_SCD is updated in the current multicast broadcast service scheduling period, the base station carries the update indication information of the MBS resource configuration parameter in the AAI_E-MBS_MAP. Specifically, referring to Table 1, the update indication information may be an update indicator, indicating an indication of whether the multicast broadcast service resource configuration information changes in the AAI_SCD message during the scheduling period of the previous multicast broadcast service. . Referring to Table 2, the update indication information may further include an update counter indicating an update count of multicast broadcast service resource configuration information in the AAI_SCD message. Referring to Table 3, the base station may also carry the transmission time information (including the transmission position or offset) of the updated AAI_SCD message in the AAI_E-MBS_MAP message. In this way, the terminal can correctly receive the updated AAI_SCD message. Preferably, as shown in FIG. 3, step S104 includes: receiving, by the terminal receiving the multicast broadcast service, a decoded AAI E-MBS MAP message at the beginning of each multicast broadcast service scheduling period, when the MBS in the message When the update indication bit of the resource configuration parameter indicates "update" or the update count value changes, step S106 is performed; step S106 includes: the terminal in the connection state of the carrier aggregation working mode is at the time of sending the AAI SCD message, Receive AAI_SCD for decoding update on the carrier where MBS is located The message, thereby updating the MBS resource configuration parameters saved locally by the terminal. Alternatively, the terminal in the connection state of the carrier switching mode (the carrier where the MBS is located is the secondary carrier of the terminal), before the updated AAI_SCD message is sent, if it works on the primary carrier, perform carrier switching, and switch to the corresponding Receiving the decoded AAI_SCD message on the carrier where the multicast broadcast service is located, updating the MBS resource configuration parameter saved locally by the terminal; if it does not work on the primary carrier, directly receiving the decoding update on the carrier where the currently working multicast broadcast service is located AAI_SCD message. The terminal in the sleep or idle state receives the decoded updated AAI SCD message on the carrier currently receiving the multicast broadcast service, and updates the locally saved MBS resource configuration parameter. The above preferred embodiment provides another specific implementation in which the terminal updates the locally saved MBS resource configuration parameters according to the update indication information sent by the base station in the wireless communication system. With the above preferred embodiment, the terminal in the connected state of the carrier switching mode is configured to receive the secondary carrier when the carrier where the MBS is located is the secondary carrier of the terminal (ie, the primary carrier is different from the carrier where the MBS is located). The update indication information in the AAI_E-MBS_MAP message is used to learn that the MBS resource configuration parameter of the base station side is to be updated, and before receiving the AAI_SCD message carrying the updated MBS resource configuration parameter, switch to the carrier where the MBS is located and receive the AAI_SCD message. To update the MBS resource configuration parameters. Similarly, the terminal in the sleep or idle state can also know that the MBS resource configuration parameter of the base station side is to be updated, and the AAI_SCD message carrying the updated MBS resource configuration parameter is received in time to update the MBS resource configuration parameter. Preferred Embodiment 1 In a multi-carrier system, the multi-carrier capability of the terminal can be operated in two modes, namely, carrier aggregation and carrier switching. After the network is connected, the base station allocates a primary carrier to the terminal to receive and send control and data information. When the carrier where the multicast broadcast service is located is different from the primary carrier of the terminal, the terminal operates in the carrier aggregation mode. The carrier where the broadcast service is located is its secondary carrier, and the terminal can work on the primary and secondary carriers at the same time. For the terminal that can only work in the carrier conversion mode, the primary carrier serves as the control of the unicast service and the transmission carrier of the data, and multicast The carrier where the broadcast service is located is the secondary carrier of the terminal, and the terminal performs conversion between the primary carrier and the secondary carrier, thereby receiving control and data information of the multicast broadcast service on the secondary carrier. The system configuration description message AAI_SCD sent on the carrier carrying the multicast broadcast service carries the MBS resource configuration parameter, and when the information changes and changes, an update indication is needed. In order to notify the terminal to receive the decoded updated multicast broadcast service resource configuration information at the time of sending the corresponding AAI_SCD message. As shown in FIG. 2, the system configuration description message AAI SCD sent on the carrier carrying the multicast broadcast service carries the MBS resource configuration parameter on the carrier, and is used to describe one or more multicast broadcast service areas on the carrier. Resource allocation information with the unicast service area and multicast broadcast service scheduling period information, and the like. The terminal receives the decoded AAI SCD message on the carrier at a corresponding moment by reading the AAI E-MBS_CFG on the corresponding carrier to obtain indication information of whether the MBS resource configuration parameter in the AAI SCD message is about to be updated. As shown in Table 1, the SAI update indicator bit (SCD update indicator) is carried in the AAI_E-MBS_CFG message, indicating that the AAI_SCD message on the corresponding multicast broadcast service carrier is in the life (modification) period of the AAI_E-MBS_CFG message. Whether the MBS resource configuration parameters have changed. If there is a change, if the terminal with the carrier switching capability is in the active state before the sending moment of the next AAI_SCD message on the carrier, the terminal determines whether it needs to switch to the carrier according to the current carrier position (at the current If the carrier is the primary carrier, it needs to be switched to the secondary carrier, otherwise it does not need to be switched) and receives the updated MBS resource configuration parameter in the AAI_SCD message. If the terminal with the carrier switching capability is in the idle state, the terminal is in the The updated MBS resource configuration parameter in the AAI_SCD message is received and decoded on the carrier. If the terminal has carrier aggregation capability, the terminal receives the updated MBS resource configuration parameter in the AAI_SCD message on the multicast broadcast service carrier. As shown in Table 2, the base station may also carry the transmission period or location information (ie, the transmission time information described above) of the SCD message in the AAI_E-MBS_CFG message, such as: a superframe period, and/or a superframe offset, and/or Frame number or frame offset, and/or subframe number or subframe offset. The preferred embodiment 2, as shown in Table 3, carries an SCD update count (SCD change count) in the AAI_E-MBS_CFG message, indicating that the live broadcast (modified) period of the AAI_E-MBS_CFG message is on the corresponding multicast broadcast service carrier. The update count of the MBS resource configuration parameter in the AAI_SCD message, for example, when the "change count" changes, indicates that the MBS resource configuration parameter in the AAI_SCD message sent during the life (modification) period of this AAI_E-MBS_CFG message will change. Before the sending moment of the next AAI_SCD message on the carrier, if the terminal with the carrier switching capability is in the active state, the terminal is located at the current carrier position, and it is determined whether it is necessary to switch to the carrier (the current carrier is the primary carrier, Then you need to switch to the secondary carrier, if the current load If the wave is not the primary carrier, the switch does not need to be switched) and receives the updated MBS resource configuration parameter in the AAI_SCD message; if the terminal with the carrier switching capability is in the idle state, the terminal receives the decoded AAI_SCD message on the carrier. Updated MBS resource configuration parameters in . As shown in FIG. 2, the AAI_SCD sent on the carrier carrying the multicast broadcast service carries the MBS resource configuration parameter on the carrier, and is used to describe one or more multicast broadcast service areas and unicasts on the carrier. Resource allocation information of the service area and scheduling information of the multicast broadcast service. The terminal obtains the indication information that the MBS resource configuration parameter in the AAI_SCD message is about to be updated by reading the AAI_E-MBS_MAP on the carrier, so as to receive the decoded AAI SCD message on the carrier at the corresponding moment, and in the AAI_SCD message. The MBS resource configuration parameter updates the locally saved MBS resource configuration parameters. The third embodiment of the present invention, as shown in FIG. 3, carries an SCD update indication bit (shown in Table 4) in the AAI_E-MBS_MAP message, indicating that the multicast broadcast service carrier is on the multicast broadcast service scheduling period. Whether the MBS resource configuration parameter in the AAI_SCD message has changed. If the change occurs, before the sending moment of the next AAI_SCD message on the carrier, if the terminal with the carrier switching capability is in the active state, the terminal determines whether it needs to switch to the carrier according to the current carrier position (in the case of If the current carrier is the primary carrier, the switch needs to be switched to the secondary carrier. If the current carrier is not the primary carrier, no handover is required, and the updated MBS resource configuration parameter in the AAI_SCD message is received. After the terminal is in an idle state, the terminal receives the updated MBS resource configuration parameter in the AAI_SCD message on the carrier. If the terminal has the carrier aggregation capability, the terminal receives the updated MBS resource configuration parameter in the AAI SCD message on the multicast broadcast service carrier, and updates the locally saved MBS resource by using the MBS resource configuration parameter in the AAI_SCD message. Configuration parameters. Table 4

如表 5所示，基站还可以在 AAI_E-MBS_CFG消息中携带 SCD消息的发送时间信息（发送周期或位置信息），如：超帧周期、和 /或超帧偏移、和 / 或帧号或帧偏移、和 /或子帧号或子帧偏移。表 5

As shown in Table 5, the base station may also carry the transmission time information (transmission period or location information) of the SCD message in the AAI_E-MBS_CFG message, such as: superframe period, and/or superframe offset, and/or frame number or Frame offset, and/or subframe number or subframe offset. table 5

优选实施例四如图 3所示，在 AAI_E-MBS_MAP消息中携带一个 SCD更新计数器（如表 6 所示），指示在此多播广播业务调度周期内，相应多播广播业务载波上的 AAI_SCD消息中的 MBS资源配置参数的更新计数，例如当 "change count" 发生变化时，表示此调度内发送的 AAI_SCD消息中的 MBS资源配置参数将发生变化。在所述载波上的下一个 AAI_SCD 消息的发送时刻前，若具有载波切换能力的终端处于激活状态，终端根据当前所在载波位置，判断是否需要切换到所述载波上（在当前所在载波为主载波，则需要切换到辅载波上，若当前所在载波不是主载波，则无需切换）并接收解码所述 AAI_SCD 消息中的更新后的 MBS 资源配置参数；若具有载波切换能力的终端处于空闲状态，终端则在所述载波上接收解码所述 AAI_SCD消息中的更新后的 MBS资源配置参数。表 6 The preferred embodiment 4, as shown in FIG. 3, carries an SCD update counter (shown in Table 6) in the AAI_E-MBS_MAP message, indicating that the AAI_SCD message on the corresponding multicast broadcast service carrier is within the multicast broadcast service scheduling period. The update count of the MBS resource configuration parameter in the middle, for example, when the "change count" changes, it indicates that the MBS resource configuration parameter in the AAI_SCD message sent in this schedule will change. Before the sending moment of the next AAI_SCD message on the carrier, if the terminal with the carrier switching capability is in the active state, the terminal determines whether it needs to switch to the carrier according to the current carrier position (the current carrier is the primary carrier) The switch needs to be switched to the secondary carrier. If the current carrier is not the primary carrier, the switch does not need to be switched) and receives the updated MBS resource configuration parameter in the AAI_SCD message.

图 4是才艮据本发明另一种实施例的 MBS资源配置参数的更新方法的流程图，如图 4所示，该流程包括以下步骤：步骤 S402, 基站发送***配置描述消息（AAI_SCD ), 其中，该***配置描述消息中携带更新的 MBS资源配置参数；步骤 S404, 基站在第一 MBS调度周期的起始处启用该更新的 MBS资源配置参数。其中，第一 MBS调度周期为基站发送上述携带更新的 MBS资源配置参数的***配置描述消息后的下一个 MBS调度周期，或者为下一个 MBS配置消息的发送或生命周期内的第一个 MBS调度周期。相关技术中，基站启用 AAI_SCD 消息中的参数的时间与多播广播业务的调度周期没有直接的关系，如果 AAI_SCD 消息中与多播广播业务相关的参数发生更新时，若此参数的更新生效时间与多播广播业务的调度周期无关，则将会影响基站对于多播广播业务的发送及终端的接收。而本实施例由于限定基站在 MBS调度周期的起始处启用该更新的 MBS资源配置参数，即进行基站侧的 MBS 资源配置参数的更新，解决了相关技术中存在的上述问题，从而能够确保基站在 MBS 调度周期的起始处进行 MBS 资源配置参数的更新，实现了基站对于多播广播业务的正常发送及终端对于 MBS的正常接收。优选地，在上述的方法中，还包括：步骤 S406, 终端在第二 MBS调度周期的起始处，以接收到的***配置描述消息中携带的更新的 MBS 资源配置参数更新本地保存的 MBS资源配置参数。相关技术中，终端按照该 AAI_SCD消息更新 MBS资源配置参数的时间可能是在某个调度周期内的某个时刻（即***配置描述消息的发送时间与多播广播业务的调度周期无法对齐），导致终端根据该更新后的多播广播业务的资源配置信息无法正常接收解码相应资源上的业务数据。本实施例中，终端接收到 AAI_SCD 消息后，在多播广播业务调度周期的起始处（即上述的第二 MBS调度周期的起始处）才进行 MBS资源配置参数的更新，从而确定多播广播业务资源配置信息更新的生效时间，保证在某个多播广播业务调度周期的开始位置进行更新，以便终端能在下一个或某个多播广播业务的调度周期开始时按照更新的配置信息接收解码相应资源上的业务数据，以确保多播广播业务数据的正确接收。优选地，步骤 S406包括：更新生效时间（即第二 MBS调度周期）缺省为终端接收到上述携带更新的 MBS 资源配置参数的***配置描述消息后的下一个多播广播业务调度周期的起始处，或者为下一个多播广播业务配置消息 AAI E-MBS_CFG消息的生命 (修改）周期内的第一个多播广播业务调度周期的起始处，终端在该缺省更新生效时间更新本地保存的 MBS 资源配置参数。上述更新方法可以称为隐式方式。优选地，步骤 S402中的 AAI_SCD消息中还携带有 MBS资源配置参数的更新生效时间指示信息（即用于指示终端以接收到的更新的 MBS 资源配置参数更新本地保存的配置参数的时间），其中，该更新生效时间指示信息包括更新生效时间的方式（即隐式方式或显式方式）和 /或更新生效的时间偏移信息。则，步骤 S404 包括：基站在该更新生效时间指示信息所指示的第一 MBS调度周期的起始处，启用该更新的 MBS资源配置参数；步骤 S406包括：终端在该更新生效时间指示信息所指示的第二 MBS调度周期的起始处，以该更新的 MBS 资源配置参数更新本地保存的 MBS 资源配置参数。步骤 S404 中该更新生效时间指示信息所指示的第一调度周期可以为基站发送携带更新的 MBS资源配置参数的 AAI_SCD消息后的下一个多播广播业务调度周期的起始处，或者为下一个 AAI_E-MBS_CFG消息的生命 (修改）周期内的第一个多播广播业务调度周期的起始处，或者为超帧号或超帧偏置。从而，终端在该更新生效时间指示信息所指示的时间进行本地 MBS 资源配置参数的更新。上述更新方法可以称为显式方式。其中，若更新生效时间的方式为隐式方式，则终端接收到携带更新的 MBS资源配置参数的 AAI_SCD后，在第二 MBS调度周期的起始处进行更新；若为显式方式，则终端接收到携带更新的 MBS资源配置参数的 AAI_SCD 后，在更新生效的时间偏移信息所指示的时间进行更新。其中，上述的更新生效时间指示信息还可以通过 AAI_E-MBS_CFG消息或 AAI_E-MBS_MAP信息发送。因此，在步骤 S406之前，还包括：基站发送携带用于指示终端更新 MBS 资源配置参数的时间的更新生效时间指示信息的 MBS配置消息或 MBS资源映射消息，其中，该更新生效时间指示信息包括更新生效时间的方式和 /或更新生效的时间偏移信息；步骤 S404包括：基站在上述更新生效时间指示信息所指示的第一 MBS 调度周期的起始处，启用该更新的 MBS资源配置参数；步骤 S406包括：终端在上述更新生效时间指示信息所指示的第二 MBS 调度周期的起始处，以该更新的 MBS资源配置参数更新本地保存的 MBS资源配置参数。上述优选实施例提供了终端釆用隐式方式或显式方式以接收到的 AAI SCD 中所携带的 MBS 资源配置参数进行本地更新的两种具体实施方案，在显式方式中更新生效时间可以通过特定的指示信息（即上述的更新生效时间指示信息）指示给终端。优选实施例五如图 2和图 3所示， AAI_SCD中所携带的 MBS资源配置参数发生更新时，其生效时间可以通过隐式的方式进行指示。具体地，多播广播业务资源配置信息更新生效时间缺省为 AAI_SCD消息后的下一个多播广播业务调度周期，或者为下一个多播广播业务配置消息 AAI_E-MBS_CFG生命（修改）周期内的第一个多播广播业务调度周期。终端通过任意一种方式获得 AAI_SCD消息中的更新后的 MBS资源配置参数后，按照缺省更新生效时间更新本地保存的 MBS 资源配置参数，并继续接收相应的多播广播业务。优选实施例六如图 2和图 3所示， AAI_SCD中所携带的 MBS资源配置参数发生更新时，其生效时间可以通过显式的方式进行指示。具体地， AAI_SCD消息中携带 MBS资源配置参数的更新生效指示字段（即更新生效时间指示信息）。更新生效指示字段可以指示多种生效偏置，例如生效时间为下一个多播广播业务调度周期（MSI )或者 AAI_E-MBS_CFG发送周期的起始处，或者为下一个 AAI_E-MBS_CFG消息的生命（修改）周期内的第一个多播广播业务调度周期的起始处，或者为超帧号或超帧偏置。如表 7所示。表 7

( SCD更新生效偏置）下一个 MSI生效； 4 is a flowchart of a method for updating an MBS resource configuration parameter according to another embodiment of the present invention. As shown in FIG. 4, the process includes the following steps: Step S402: A base station sends a system configuration description message (AAI_SCD), The system configuration description message carries the updated MBS resource configuration parameter. Step S404: The base station enables the updated MBS resource configuration parameter at the beginning of the first MBS scheduling period. The first MBS scheduling period is the next MBS scheduling period after the base station sends the system configuration description message carrying the updated MBS resource configuration parameter, or is the next MBS configuration message transmission or the first MBS scheduling in the life cycle. cycle. In the related art, the time when the base station enables the parameter in the AAI_SCD message is not directly related to the scheduling period of the multicast broadcast service. If the parameter related to the multicast broadcast service in the AAI_SCD message is updated, if the update time of the parameter is valid, Regardless of the scheduling period of the multicast broadcast service, the base station will affect the transmission of the multicast broadcast service and the reception of the terminal. In this embodiment, the base station is configured to enable the updated MBS resource configuration parameter at the beginning of the MBS scheduling period, that is, to update the MBS resource configuration parameter on the base station side, thereby solving the above problems in the related art, thereby ensuring the base station. The MBS resource configuration parameter is updated at the beginning of the MBS scheduling period, and the normal transmission of the multicast broadcast service by the base station and the normal reception of the terminal by the terminal are implemented. Preferably, in the foregoing method, the method further includes: Step S406: The terminal updates the locally saved MBS resource by using the updated MBS resource configuration parameter carried in the received system configuration description message at the beginning of the second MBS scheduling period. Configuration parameters. In the related art, the time for the terminal to update the MBS resource configuration parameter according to the AAI_SCD message may be some time in a certain scheduling period (that is, the sending time of the system configuration description message cannot be aligned with the scheduling period of the multicast broadcast service), resulting in The terminal cannot receive and decode the service data on the corresponding resource according to the resource configuration information of the updated multicast broadcast service. In this embodiment, after receiving the AAI_SCD message, the terminal performs the update of the MBS resource configuration parameter at the beginning of the multicast broadcast service scheduling period (ie, at the beginning of the second MBS scheduling period), thereby determining the multicast. The effective time of the broadcast service resource configuration information update is guaranteed to be updated at the beginning of a multicast broadcast service scheduling period, so that the terminal can schedule the next or a certain multicast broadcast service. At the beginning of the period, the service data on the corresponding resource is received and decoded according to the updated configuration information to ensure correct reception of the multicast broadcast service data. Preferably, step S406 includes: the update effective time (ie, the second MBS scheduling period) defaults to the start of the next multicast broadcast service scheduling period after the terminal receives the system configuration description message carrying the updated MBS resource configuration parameter. Or, at the beginning of the first multicast broadcast service scheduling period in the life (modification) period of the next multicast broadcast service configuration message AAI E-MBS_CFG message, the terminal updates the local save at the default update effective time. MBS resource configuration parameters. The above update method can be called an implicit method. Preferably, the AAI_SCD message in step S402 further carries the update effective time indication information of the MBS resource configuration parameter (that is, the time for instructing the terminal to update the locally saved configuration parameter with the received updated MBS resource configuration parameter), where The update effective time indication information includes a manner of updating the effective time (ie, implicit mode or explicit mode) and/or time offset information of the update effective. Then, the step S404 includes: the base station enables the updated MBS resource configuration parameter at the beginning of the first MBS scheduling period indicated by the update effective time indication information; Step S406 includes: the terminal is indicated by the update effective time indication information At the beginning of the second MBS scheduling period, the locally saved MBS resource configuration parameters are updated with the updated MBS resource configuration parameters. The first scheduling period indicated by the update effective time indication information in step S404 may be the start of the next multicast broadcast service scheduling period after the base station sends the AAI_SCD message carrying the updated MBS resource configuration parameter, or is the next AAI_E - The beginning of the first multicast broadcast service scheduling period within the lifetime (modification) period of the MBS_CFG message, or the superframe number or superframe offset. Thereby, the terminal performs the update of the local MBS resource configuration parameter at the time indicated by the update effective time indication information. The above update method can be referred to as an explicit method. If the mode of the update effective time is the implicit mode, the terminal receives the AAI_SCD carrying the updated MBS resource configuration parameter, and then updates the start of the second MBS scheduling period; if it is the explicit mode, the terminal receives After the AAI_SCD carrying the updated MBS resource configuration parameter, the update is performed at the time indicated by the time offset information in which the update takes effect. The foregoing update effective time indication information may also be sent by using an AAI_E-MBS_CFG message or an AAI_E-MBS_MAP information. Therefore, before the step S406, the method further includes: the base station sending, by the base station, an MBS configuration message or an MBS resource mapping message, where the update effective time indication information is used to indicate that the terminal updates the MBS resource configuration parameter, where the update effective time indication information includes an update. The time of the effective time and/or the time offset information that the update takes effect; Step S404 includes: the base station enables the updated MBS resource configuration parameter at the beginning of the first MBS scheduling period indicated by the update effective time indication information; Step S406 includes: the terminal indicates, by the update effective time indication information At the beginning of the second MBS scheduling period, the locally saved MBS resource configuration parameters are updated with the updated MBS resource configuration parameters. The foregoing preferred embodiment provides two specific implementation manners for the terminal to perform local update by using the MBS resource configuration parameter carried in the received AAI SCD in an implicit manner or an explicit manner. In an explicit manner, the update effective time can be adopted. The specific indication information (ie, the update effective time indication information described above) is indicated to the terminal. In the fifth embodiment, as shown in FIG. 2 and FIG. 3, when the MBS resource configuration parameter carried in the AAI_SCD is updated, the effective time can be indicated in an implicit manner. Specifically, the multicast broadcast service resource configuration information update effective time defaults to the next multicast broadcast service scheduling period after the AAI_SCD message, or the next time in the next multicast broadcast service configuration message AAI_E-MBS_CFG life (modification) period A multicast broadcast service scheduling period. After obtaining the updated MBS resource configuration parameter in the AAI_SCD message, the terminal updates the locally saved MBS resource configuration parameter according to the default update effective time, and continues to receive the corresponding multicast broadcast service. In the sixth embodiment, as shown in FIG. 2 and FIG. 3, when the MBS resource configuration parameter carried in the AAI_SCD is updated, the effective time can be indicated in an explicit manner. Specifically, the AAI_SCD message carries an update validity indication field (ie, an update effective time indication information) of the MBS resource configuration parameter. The update effective indication field may indicate multiple effective offsets, for example, the effective time is the start of the next multicast broadcast service scheduling period (MSI) or the AAI_E-MBS_CFG transmission period, or the life of the next AAI_E-MBS_CFG message (modification) The beginning of the first multicast broadcast service scheduling period in the period, or the superframe number or superframe offset.
