一种实现睡眠模式的方法及移动终端A method and mobile terminal for realizing sleep mode

本申请是申请号为CN200680012383.8，申请日为2006年6月13日、发明主题为“一种睡眠模式下业务指示消息发送方法及装置”的中国在先申请的分案申请。This application is a divisional application of a Chinese prior application with the application number CN200680012383.8, the application date is June 13, 2006, and the subject of the invention is "A Method and Device for Sending Service Instruction Messages in Sleep Mode".

技术领域technical field

本发明涉及移动通信领域，尤其涉及一种实现睡眠模式的方法及移动终端。The invention relates to the field of mobile communication, in particular to a method for realizing a sleep mode and a mobile terminal.

背景技术Background technique

在移动通信系统中，待机时间的长短对于终端的移动自由度有着非常大的影响，延长待机时间可以通过两种方式来实现，一种方式是采用高效的电池；另一种方式是尽可能的减少移动终端的无谓功率消耗。IEEE(Institute ofElectrical and Electronic Engineers，电子电气工程师协会)802.16e是一个正在制定过程中的移动宽带无线接入系统标准，IEEE802.16e的D8草案中定义的移动终端睡眠模式就属于后一种方式。所谓睡眠模式是移动终端在与基站预先协商的时间区间内，空口暂时中断与基站联系的过程。实现睡眠模式过程可以减少移动终端在上行链路和下行链路上的传输请求，从而减少MSS的功率消耗。In a mobile communication system, the length of standby time has a great impact on the freedom of movement of the terminal. There are two ways to extend the standby time. One way is to use high-efficiency batteries; Reduce unnecessary power consumption of the mobile terminal. IEEE (Institute of Electrical and Electronic Engineers, Institute of Electrical and Electronics Engineers) 802.16e is a mobile broadband wireless access system standard in the process of being formulated, and the mobile terminal sleep mode defined in the D8 draft of IEEE802.16e belongs to the latter mode. The so-called sleep mode is a process in which the mobile terminal temporarily interrupts the connection with the base station through the air interface within the time interval negotiated with the base station in advance. Implementing sleep mode procedures can reduce the mobile terminal's transmission requests on the uplink and downlink, thereby reducing the power consumption of the MSS.

MSS可以主动向Serving BS(Serving Base Station，服务基站)发送睡眠请求消息MOB_SLP_REQ请求进入睡眠模式，然后Serving BS发送睡眠响应消息MOBS_LP_RSP来同意或拒绝MSS进入睡眠模式。也可以由BS主动发送睡眠响应消息MOB_SLP_RSP来要求MSS进入睡眠模式，MSS收到后，一般情况下根据睡眠响应消息MOB_SLP_RSP中携带的参数进入睡眠模式。MSS can actively send a sleep request message MOB_SLP_REQ to Serving BS (Serving Base Station, serving base station) to request to enter sleep mode, and then Serving BS sends sleep response message MOBS_LP_RSP to agree or reject MSS to enter sleep mode. The BS can also actively send the sleep response message MOB_SLP_RSP to request the MSS to enter the sleep mode. After receiving the message, the MSS generally enters the sleep mode according to the parameters carried in the sleep response message MOB_SLP_RSP.

目前前述协议规定，MSS和BS进行商议，将当前的服务流根据其QoS(Quality of Service，服务质量)要求和特性分为3类睡眠组，对不同类别的睡眠组分别采取不同的睡眠策略，每一类可以包含多个睡眠组，同一类别的睡眠组与睡眠组之间采用相同的睡眠策略和不同的睡眠参数，睡眠参数根据每一组中具体包括的业务特点选择。每一睡眠组可以包含多个服务流，每个服务流代表MSS和BS之间的业务连接，可以是上行或下行，通过一个16比特的连接标识符(CID，Connection Identifier)来标识。每一个睡眠组的睡眠状态分为激活状态和非激活状态。在激活状态下，本睡眠组的睡眠状态机正常进行；在非激活状态下，本睡眠组的睡眠状态机复位，停止进行。MSS可以存在多个睡眠组，与所有睡眠组的侦听窗口不重叠的时间区域为不可用区间(Unavailability interval)，与Unavailability interval不重叠的其它时间段为可用区间(Availability interval)。MSS只有在不可用区间才是真正处于睡眠状态，此时该MSS的所有睡眠组都在睡眠窗口状态。在可用区间内，可以有某些睡眠组处于睡眠窗口状态，其它睡眠组处于侦听状态，MSS实际上在清醒状态，只不过各个睡眠组的睡眠状态机处于不同的状态下。At present, the aforementioned agreement stipulates that MSS and BS negotiate to divide the current service flow into three types of sleep groups according to their QoS (Quality of Service) requirements and characteristics, and adopt different sleep strategies for different types of sleep groups. Each category can contain multiple sleep groups, and sleep groups of the same category adopt the same sleep strategy and different sleep parameters, and the sleep parameters are selected according to the specific service characteristics included in each group. Each sleep group can contain multiple service flows, and each service flow represents a service connection between the MSS and the BS, which can be uplink or downlink, and is identified by a 16-bit connection identifier (CID, Connection Identifier). The sleep state of each sleep group is divided into active state and inactive state. In the activated state, the sleep state machine of the sleep group is normally in progress; in the inactive state, the sleep state machine of the sleep group is reset and stopped. MSS can have multiple sleep groups, and the time zone that does not overlap with the listening windows of all sleep groups is an unavailable interval (Unavailability interval), and other time periods that do not overlap with the Unavailability interval are available intervals (Availability interval). The MSS is really in the sleep state only in the unavailable interval, and at this time all the sleep groups of the MSS are in the sleep window state. In the available interval, some sleep groups may be in the sleep window state, other sleep groups are in the listening state, and the MSS is actually in the awake state, but the sleep state machines of each sleep group are in different states.

第一类睡眠组定义为Power_Saving_Class_Type＝1，一般应用于实时性要求不高的业务。它的睡眠策略是采用固定的侦听窗口长度和可变的睡眠窗口长度，侦听窗口和睡眠窗口交替，当前睡眠窗口长度依次为上一次睡眠窗口长度的2倍，直到达到规定的最大值，然后保持不变和侦听窗口交替进行。直到MSS或BS发起睡眠状态改变请求，设置睡眠状态为非激活状态，此睡眠组的睡眠状态机才停止。The first type of sleep group is defined as Power_Saving_Class_Type=1, which is generally applied to services with low real-time requirements. Its sleep strategy is to use a fixed listening window length and a variable sleep window length. The listening window and the sleeping window alternate. The current sleeping window length is twice the length of the previous sleeping window until it reaches the specified maximum value. Then hold constant and listen windows alternate. The sleep state machine of this sleep group does not stop until the MSS or BS initiates a sleep state change request and sets the sleep state to an inactive state.

第二类睡眠组定义为Power_Saving_Class_Type＝2，一般应用于周期性发送数据的业务。它的睡眠策略是采用固定的侦听窗口长度和固定的睡眠窗口长度，然后睡眠窗口和侦听窗口交替出现，直到MSS或BS发起睡眠状态改变请求，设置睡眠状态为非激活状态，此睡眠组的睡眠状态机才停止。The second type of sleep group is defined as Power_Saving_Class_Type=2, which is generally applied to services that periodically send data. Its sleep strategy is to use a fixed length of the listening window and a fixed length of the sleep window, and then the sleep window and the listening window appear alternately until the MSS or BS initiates a sleep state change request, sets the sleep state to an inactive state, and the sleep group The sleep state machine is stopped.

第三类睡眠组定义为Power_Saving_Class_Type＝3，一般应用于多播业务。它采用的睡眠策略是只设置一次睡眠窗口，在睡眠窗口超时后此睡眠组的睡眠状态为非激活状态，睡眠状态机停止，直到MSS或BS通过消息交互重新激活此组的睡眠状态机。The third type of sleep group is defined as Power_Saving_Class_Type=3, which is generally applied to multicast services. The sleep strategy it adopts is to set the sleep window only once. After the sleep window times out, the sleep state of this sleep group is inactive, and the sleep state machine stops until the MSS or BS reactivates the sleep state machine of this group through message interaction.

对于第一类睡眠组而言，BS可以在这类睡眠组的侦听窗口期间发送业务指示消息MOB_TRF_IND，用来指示是否有针对这个睡眠组的服务流的业务数据。MSS中第一类睡眠组中各个睡眠组在Availability interval区间如果接收到的业务指示消息中指示有针对本睡眠组的业务数据，则该睡眠组的睡眠状态变为非激活状态，睡眠状态机复位；如果没有，则这个睡眠组的睡眠状态仍为激活状态，睡眠状态机照常进行，在侦听窗口结束以后进入睡眠状态；如果有针对这个睡眠组中业务流的业务数据，则这个睡眠组的睡眠状态转为非激活状态，睡眠状态机复位。For the first type of sleep group, the BS may send a traffic indication message MOB_TRF_IND during the listening window of this type of sleep group to indicate whether there is traffic data for the service flow of this sleep group. If each sleep group in the first type of sleep group in the MSS indicates that there is service data for this sleep group in the service indication message received in the Availability interval interval, the sleep state of the sleep group becomes inactive, and the sleep state machine is reset. ; If not, the sleep state of this sleep group is still active, and the sleep state machine proceeds as usual, and enters the sleep state after the listening window ends; if there is business data for the traffic flow in this sleep group, the sleep state machine The sleep state becomes inactive and the sleep state machine resets.

图1是一个MSS中存在两个睡眠组的睡眠状态示意图，第一个睡眠组110属于第一类睡眠组，BS分配固定长度的侦听窗口111和依次为上一次睡眠窗口2倍的睡眠窗口112；第二个睡眠组120属于第二类睡眠组，BS分配固定长度的侦听窗口121和睡眠窗口122。斜线区域130显示了两类睡眠组的综合效果，其中：有阴影的斜线区间131为Availability intervals，无阴影的斜线区间132为Unavailability intervals。Figure 1 is a schematic diagram of the sleep state of two sleep groups in an MSS. Thefirst sleep group 110 belongs to the first type of sleep group, and the BS allocates a fixed-length listening window 111 and a sleep window twice as long as the previous sleep window. 112 ; thesecond sleep group 120 belongs to the second type of sleep group, and the BS allocates alistening window 121 and asleep window 122 with fixed lengths. The hatchedarea 130 shows the combined effect of the two sleep groups, wherein: the shaded hatchedinterval 131 is Availability intervals, and the unshadedhatched interval 132 is Unavailability intervals.

目前802.16e/D8草案中关于业务指示消息的设计，进行如下的规定：In the current 802.16e/D8 draft, the design of the service indication message is stipulated as follows:

1、业务指示消息只针对第一类睡眠组设置。1. The service indication message is only set for the first type of sleep group.

2、BS通过发送业务指示消息来停止第一类睡眠组的激活状态。2. The BS stops the activation state of the first type of sleep group by sending a service indication message.

3、如果MSS在睡眠请求消息MOB_SLP_REQ中设置了TRF_IND_Required标志位，则MSS如果在Availability interval期间如果没有接收到业务指示消息MOB_TRF_IND，则这个睡眠组将在Availablity interval结束后自动变为非激活状态。3. If the MSS sets the TRF_IND_Required flag in the sleep request message MOB_SLP_REQ, if the MSS does not receive the service indication message MOB_TRF_IND during the availability interval, the sleep group will automatically become inactive after the availability interval ends.

4、对于第一类睡眠组，BS可以为每个睡眠组分配一个SLPID(睡眠组标识)，用来标识各个MSS上不同的睡眠组(每个睡眠组对应一个唯一的SLPID)。BS可以在业务指示消息MOB_TRF_IND中通过SLPID来指示各个睡眠组是否有业务下发。4. For the first type of sleep group, the BS can assign a SLPID (sleep group identifier) to each sleep group to identify different sleep groups on each MSS (each sleep group corresponds to a unique SLPID). The BS may use the SLPID in the service indication message MOB_TRF_IND to indicate whether each sleep group has a service to deliver.

本模式下，基于SLPID进行业务指示，通过两个映射表，SLPID GroupIndication bit_map(睡眠组指示比特映射)和Traffic Indication bit_map(睡眠组业务指示比特映射)，来进行相关睡眠组的业务指示。In this mode, the service indication is based on SLPID, and the service indication of the relevant sleep group is performed through two mapping tables, SLPID GroupIndication bit_map (sleep group indication bit map) and Traffic Indication bit_map (sleep group service indication bit map).

SLPID Group Indication bit_map如图2所示。其中1024个SLPID分为32个业务指示单元，每个业务指示单元包括32个SLPID，每个业务指示单元对应于SLPID Group Indication bit_map中的1个比特。The SLPID Group Indication bit_map is shown in Figure 2. The 1024 SLPIDs are divided into 32 service indication units, each service indication unit includes 32 SLPIDs, and each service indication unit corresponds to 1 bit in the SLPID Group Indication bit_map.

其中每个比特的意义：The meaning of each bit:

0：该比特对应的业务指示单元内的所有SLPID对应的睡眠组都没有业务指示。0: The sleep group corresponding to all SLPIDs in the service indication unit corresponding to this bit has no service indication.

1：该比特对应的业务指示单元中至少有一个SLPID对应的睡眠组有业务指示。1: In the service indication unit corresponding to this bit, at least one sleep group corresponding to the SLPID has a service indication.

Traffic Indication bit_map如图3所示。其中Traffic Indaication bit_map包含若干个业务指示单元，这些业务指示单元依次对应SLPID Group Indicationbit_map中比特位为1的比特所对应的业务指示单元。每个业务指示单元为32bit，每一bit对应于该业务指示单元中的一个SLPID，如果bit＝0表示该SLPID对应的睡眠组没有业务，bit＝1表示该SLPID对应的睡眠组有业务存在。Traffic Indication bit_map is shown in Figure 3. The Traffic Indication bit_map includes several service indication units, and these service indication units in turn correspond to the service indication units corresponding to the bits whose bit is 1 in the SLPID Group Indication bit_map. Each service indication unit is 32 bits, each bit corresponds to a SLPID in the service indication unit, if bit=0 indicates that the sleep group corresponding to the SLPID has no service, bit=1 indicates that the sleep group corresponding to the SLPID has service.

5、如果MSS内的所有睡眠组都有业务指示或都没有业务指示，则可以采用Short Basic CID(缩短的基本连接标识)方式来对MSS的各个睡眠组进行统一指示，有业务指示，则列出该MSS的Short Basic CID，反之则不列出。5. If all the sleep groups in the MSS have service instructions or have no service instructions, you can use the Short Basic CID (shortened basic connection identifier) method to uniformly indicate each sleep group in the MSS. If there are service instructions, then list List the Short Basic CID of the MSS, otherwise it will not be listed.

现有的上述方案，本领域技术人员通常称为映射指示法和缩短的基本连接标识指示法。Those skilled in the art usually refer to the above existing schemes as the mapping indication method and the shortened basic connection identification indication method.

目前协议规定业务指示消息MOB_TRF_IND的格式如表1所示：The current agreement stipulates that the format of the service instruction message MOB_TRF_IND is shown in Table 1:

目前802.16e/D8草案中关于BS向MSS发送业务指示消息MOB_TRF_IND的方案存在以下不足：In the current 802.16e/D8 draft, there are the following deficiencies in the solution for the BS to send the service indication message MOB_TRF_IND to the MSS:

1、在利用SLPID进行睡眠业务指示时采用的是映射方法，在有些情况下，例如只有很少个数的睡眠组有业务数据，如果采用映射的方式要浪费很多带宽资源。1. When SLPID is used for sleep service indication, the mapping method is adopted. In some cases, for example, only a small number of sleep groups have service data. If the mapping method is used, a lot of bandwidth resources will be wasted.

2、该方案设计不够灵活，只能采用SLPID映射的方式进行业务指示，或者只能采用Short Basic CID的方式进行指示。上述两种方案只能是择一的关系，这无形中增加了网络负担。2. The design of this solution is not flexible enough, and only the way of SLPID mapping can be used for business indication, or the way of Short Basic CID can only be used for indication. The above two solutions can only be an optional relationship, which virtually increases the network burden.

具体实施方式Detailed ways

下面结合说明书附图来说明本发明的具体实施方式。The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

本发明技术方案在保证MSS可以通过该业务指示消息获知相应的业务指示方法的前提下，节省业务指示消息的字节开销。为此，本发明的实施例修改原业务指示消息MOB_TRF_IND，增加直接采用SLPID指示的方法。同时修改原来的指示格式，将FMT(标志位)由1bit增加为3bit，将原有两种互斥的指示方案改为三种可同时选择的指示方案。每个指示比特对应一种业务指示方法，比特置1时表示采用本比特对应的业务指示方法，比特置零时表示不采用本比特对应的业务指示方法。修改后的MOB_TRF_IND消息格式如下所示。The technical solution of the present invention saves the byte overhead of the service indication message on the premise of ensuring that the MSS can know the corresponding service indication method through the service indication message. For this reason, the embodiment of the present invention modifies the original service indication message MOB_TRF_IND, and adds a method of directly using the SLPID indication. At the same time, the original indication format is modified, the FMT (flag bit) is increased from 1 bit to 3 bits, and the original two mutually exclusive indication schemes are changed into three simultaneously selectable indication schemes. Each indication bit corresponds to a service indication method. When the bit is set to 1, it indicates that the service indication method corresponding to this bit is adopted, and when the bit is set to zero, it indicates that the service indication method corresponding to this bit is not adopted. The modified MOB_TRF_IND message format is as follows.

如图4所示，是本发明睡眠模式下业务消息发送方法的流程示意图，从图4中可见，本发明主要包括以下步骤：As shown in Figure 4, it is a schematic flow diagram of the method for sending business messages in the sleep mode of the present invention. As can be seen from Figure 4, the present invention mainly includes the following steps:

S1、BS向MSS发送业务指示消息。S1. The BS sends a service indication message to the MSS.

BS向MSS发送业务指示消息，所述的业务指示消息中设置标志位，用以标识睡眠组的业务下发指示方法，该标志位的设置为3个比特，每个比特标识的内容分别是是否采用映射指示法、SLPID指示法和Short Basic CID指示法。该比特位置“0”为未采用对应的指示方法，该比特置“1”为采用对应的指示万法。The BS sends a service instruction message to the MSS, and a flag bit is set in the service instruction message to identify the service delivery instruction method of the sleep group. The flag bit is set to 3 bits, and the content of each bit flag is whether Use mapping indication, SLPID indication and Short Basic CID indication. The bit position "0" means that the corresponding indication method is not adopted, and the bit is set to "1" means that the corresponding indication method is adopted.

S2、MSS接收所述的业务指示消息，提取标志位信息。S2. The MSS receives the service indication message, and extracts flag bit information.

MSS在所述的业务指示消息中，提取该标志位信息，该标志位信息使用前述的3个比特承载。The MSS extracts the flag bit information from the service indication message, and the flag bit information is carried by the aforementioned 3 bits.

S3、采用所述的标志位信息对应的业务指示方法判断是否有针对各个睡眠组业务下发指令，如果有进入步骤S4，如果没有进入步骤S5。S3. Using the service instruction method corresponding to the flag bit information to determine whether there is an instruction for each sleep group service, if yes, enter step S4, if not, enter step S5.

MSS根据该3个比特的置“0”或者置“1”，即可得知本次业务指示消息采用的业务指示方法。According to setting "0" or "1" of the 3 bits, the MSS can know the service indication method adopted in this service indication message.

在这里，所述的3个比特的设定，既可以同时置“0”或者置“1”，也可以部分置“0”或者置“1”，这也是本发明较现有技术灵活的一种体现。Here, the setting of the 3 bits can be set to "0" or "1" at the same time, or partially set to "0" or "1". This is also a flexible aspect of the present invention compared with the prior art. kind of embodiment.

S4、指示有业务下发的MSS的睡眠组状态转为非激活状态，并接收所述的业务。S4. Instruct the sleep group state of the MSS that has a service to be delivered to be turned into an inactive state, and receive the service.

根据判断结果，如果有针对该睡眠组的业务指示，则说明有业务下发指令，MSS将该睡眠组状态转为非激活状态，接收所述的业务。According to the judgment result, if there is a service instruction for the sleep group, it means that there is a service instruction, and the MSS turns the sleep group state into an inactive state to receive the service.

S5、MSS的睡眠组状态保持激活状态。S5. The sleep group state of the MSS remains activated.

根据判断结果，如果没有针对该睡眠组的业务指示，则说明没有业务下发指令，MSS的睡眠组状态保持激活状态。According to the judgment result, if there is no service instruction for the sleep group, it means that no service instruction is issued, and the sleep group state of the MSS remains active.

如图5所示，是本发明根据设置的标志位判断业务下发指示方法类型的示意图。其中，该实施例中包括：步骤S51，提取标志位；步骤S52，解析该标志位的信息；步骤S531，如果标志位中Bit0＝1，则说明采用映射指示法；如果标志位中Bit1＝1，则说明采用SLPID指示法；如果标志位中Bit2＝1，则说明采用Short Basic CID指示法。As shown in FIG. 5 , it is a schematic diagram of the present invention judging the type of service delivery instruction method according to the set flag bit. Wherein, this embodiment includes: step S51, extracting the flag; step S52, analyzing the information of the flag; step S531, if Bit0=1 in the flag, then it is illustrated that the mapping indication method is adopted; if Bit1=1 in the flag , it indicates that the SLPID indication method is adopted; if Bit2=1 in the flag bit, it indicates that the Short Basic CID indication method is adopted.
