Description

一种短时隙寻呼消息的调度方法 A method of scheduling paging messages in a short slot

技术领域 FIELD

本发明涉及寻呼消息的调度方法,特别涉及短时隙寻呼消息的调度方法。 The present invention relates to a method of scheduling paging messages, scheduling method particularly relates to the short slot paging message.

背景技术 Background technique

在移动通信系统中,无线网络为了能够找到移动终端(MS)需要发起寻呼过程。 In the mobile communication system, a wireless network in order to find the mobile terminal (MS) needs to initiate a paging process. 在寻呼过程中,基站通过发送包含移动终端标识的寻呼消息在整个网络中呼叫被叫移动终端。 Paging message in the paging process, the base station comprises a mobile terminal identifier across the network by sending calls the called mobile terminal. 无线通信中的寻呼消息采用专门的信道发送, 这种信道统称为发送寻呼消息的信道。 Paging messages in wireless communications using a dedicated channel transmission, which transmits a paging channel message referred to as a channel. 目前,无线通信中发送寻呼消息的信道有寻呼信道(PCH)和前向公用控制信道(FCCCH)等。 Currently, wireless communications channel transmits a paging message with a paging channel (PCH) and a forward common control channel (FCCCH) and the like. 在移动终端侧,终端手机出于省电等因素的考虑,周期性的打开接收装置接收寻呼消息。 The mobile terminal side, the mobile phone terminal of power considerations and other factors, periodically opening receiving means for receiving a paging message. 为配合移动终端的接收周期,基站向终端手机发送具有一定时隙周期的寻呼消息,这种具有一定时隙周期的寻呼消息称为时隙寻呼消息。 With the reception cycle of the mobile terminal, the base station sends a paging message to a certain slot cycle the mobile phone terminal, which has a certain slot cycle paging message is a paging message called a slot. 现有标准中定义的时隙寻呼消息是指时隙周期为1.28*2"的寻呼消息,i为时隙周期索引(SLOT—CYCLE—INDEX),其中SLOT—CYCLE—INDEX的定义范围为0〜7。 SLOT—CYCLE—INDEX的参数中常用的有0和1 ,即常用的时隙寻呼消息的时隙周期为:1.28s和2.56s。按照现有标准规定,当前使用的时隙寻呼消息的最小寻呼周期是1.28s,即移动终端在时隙状态下最少需要等待1.28s才能接收到基站发来的时隙寻呼消息。在移动通信系统中,对于要求实现快速寻呼的移动终端而言,1.28s的等待时间过长。另外,对于要求呼叫建立时间小于2s的群组呼叫或者点对点呼叫来说,最小寻呼周期1.28s也不能完全满足这种快速寻呼的需求。现有通信的发展趋势需要系统在更短的时间内寻呼到移动终端,让移动终端能够在尽可能短的时间内做出出响应,这样的应用需求对具有更短时隙周期的时隙寻呼消息 Slots defined in the existing standard paging message refers to a slot cycle of 1.28 * 2 "paging message, i is the slot cycle index (SLOT-CYCLE-INDEX), which define the scope SLOT-CYCLE-INDEX is . 0 to 7 parameter sLOT-cYCLE-INDEX of 0 and 1 are commonly used, i.e. common slot cycle paging slot message is:. 1.28s and 2.56s prescribed by existing standards currently used slot the minimum paging cycle is 1.28s paging message, i.e., the mobile terminal minimum slot state in the wait 1.28s to the base station to receive the paging message sent by a slot in a mobile communication system, the requirements for fast paging for mobile terminals, 1.28s wait too long. Furthermore, the requirements for the group call setup time of less than 2s-point call or a call, the minimum paging cycle 1.28s can not fully meet the demand for such quick paging the development trend of the existing communication system needs to page the mobile terminal within a shorter time, so that the mobile terminal can make a response within the shortest possible time, to having a shorter slot cycle applications such gap paging message 的开发和调度提出新的要求。 Development and scheduling new demands.

IS2000 Release O协议中定义的PCH信道能支持时隙周期小于1.28s的时隙寻呼消息。 IS2000 Release O PCH channel defined in the protocol supports message slot cycle paging slot is less than 1.28s. IS2000 Release 0协议之后的相关协议新增加了FCCCH信道, 该信道也能支持时隙周期小于1.28s的时隙寻呼消息。 After IS2000 Release 0 protocol related protocols FCCCH channel is newly added, the channel time slot can support slot cycle paging message is less than 1.28s. 为了与现有技术中使用的时隙寻呼消息加以区别,将时隙周期小于1.28s的时隙寻呼消息称为短时隙寻呼消息,现有技术中使用的时隙寻呼消息称为正常时隙寻呼消息。 In order to distinguish the paging slot message used in the prior art, the slot cycle paging slot less than 1.28s message called a short message paging slot, a paging slot message used in the prior art referred to normal paging message slot. 现有技术尚未提供相应的调度方法在PCH和FCCCH等信道上发送时隙周期小于1.28s的寻呼消息。 The prior art has not provided a corresponding method of transmitting a paging message scheduling slot cycle in less than 1.28s PCH and the like FCCCH channel.

具体实施方式 Detailed ways

本发明方法的核'"、思想是:基站侧按照短时隙寻呼消息类型预先设置具有不同短时隙寻呼消息队列标识的短时隙寻呼消息队列,系统将接收到的短时隙寻呼消息根据短时隙寻呼消息标识保存到相应的消息队列中,最后系统根据系统时隙号和短时隙寻呼消息队列标识确定当前时隙需要处理的消息队列,并按先后顺序从消息队列中取消息发送。 Nuclear ' "method of the present invention, the idea is: a base station side in accordance with the short slot paging slot message type of the short short slots preset paging message queue, the system having a different short slots of the paging message queue identifier received save paging message according to the short message identifier to a corresponding paging slot message queue, the system determines the last message queue to be processed according to the current time slot number and slot system paging message queue identifier short slots, according to the order from message queue fetch message.

其中,短时隙寻呼消息队列标识包括:优先级标识、时隙周期,以及时隙队列号。 Wherein the short slot paging message queue identifier comprising: a priority identification, slot cycle, and the time slot queue number. 短时隙寻呼消息标识包括:优先级标识、时隙周期、发送时隙标识(PGSLOT),以及QPCH信息标识。 Short slot paging message identifier comprising: a priority identification, slot cycle, identifying a transmission slot (PGSLOT), and information identifying the QPCH.

为使本发明的目的、技术方案及优点更加清楚明白,以下参照附图并举实施例,对本发明进一步详细i兌明。 For purposes of this invention, the technical solution and merits thereof more apparent, the following embodiments with reference to the drawings simultaneously, i against the next in further detail the present invention. 如图l所示,本发明关于短时隙寻呼消息的调度流程包括以下步骤: , The short slot scheduling process on the paging message of the present invention comprises the steps of FIG. L:

步骤101:基站侧按照短时隙寻呼消息类型设置具有不同短时隙寻呼消息队列标识的短时隙寻呼消息队列。 Step 101: the base station side in accordance with the short slot is provided with different type of paging message paging message queue identifier the short slot of the short slot paging message queue.

本发明中将时隙周期小于1.28s的时隙寻呼消息称为短时隙寻呼消息。 In the present invention is less than 1.28s slot cycle paging slot message short slots called paging message. 由于短时隙寻呼消息只在其时隙周期的某个时隙发送,故系统对具有相同时隙周期的短时隙寻呼消息分队列保存。 Due to the short message paging slot transmitted only at a certain time slot of its slot cycle, so the system saves the short message paging slots having the same slot cycle queue points.

在本发明的实施例中,假设短时隙寻呼消息的时隙周期分别为80ms、 160ms、 320ms和640ms,系统单位时隙长为80ms,则时隙周期为80ms的短时隙寻呼消息每个时隙周期只有一个发送时隙,系统为该类型消息设置一个时隙队列号为0的消息队列;时隙周期为160ms的短时隙寻呼消息每个时隙周期有两个发送时隙,系统为该类型消息设置时隙队列号为0和1的两个消息队列;时隙周期为320ms的短时隙寻呼消息每个时隙周期有四个发送时隙,系统为该类型消息设置时隙队列号为0~3的四个消息队列;时隙周期为640ms的短时隙寻呼消息每个时隙周期有八个发送时隙,系统为该类型消息设置时隙队列号为0~7的八个消息队列。 In an embodiment of the present invention, it is assumed that the short slot cycle paging message slots are 80ms, 160ms, 320ms and 640ms, the system unit slot length is 80ms, the time slot period is short message paging slot of 80ms when the time slot period is short message paging slot in each slot cycle of 160ms has two transmission; each slot cycle is only one transmission slot, the system is provided for a type of message queue slot number to the message queue 0 gap, the system is provided for the type of message queue slot number 0 and 1 of two message queues; short slot cycle paging slot in each slot cycle of 320ms message has four transmission slots, that type system message number is provided four slot queue message queues 0 to 3; short slot cycle paging message slots in each slot cycle of 640ms eight transmission slot system is provided for the type of message slot queue No. 0 to 7 to eight message queue.

对于时隙周期相同,且都在同一个时隙发送的短时隙寻呼消息,基站侧按照该消息的业务类型设置不同的短时隙寻呼消息队列,并用优先级标识区分不同业务类型的消息队列。 For the same slot period, and the short slot in the same time slot paging message transmitted from the base station side in accordance with the type of service the message different short time slot paging message queue, and to distinguish between different types of service using the priority identification message queue. 比如:基站可以设置具有高优先级标识的消息队列保存呼叫相关的寻呼消息,设置具有低优先级标识的消息队列保存呼叫非相关的寻呼消息。 For example: The base station can be set to save the message queue having a high priority call identifier associated with the paging message, setting message having low priority queue identifier stored non-call related paging message.

对于具有相同优先级标识的短时隙寻呼消息队列,系统设置的消息队列类型如表一所示。 Short slot for paging messages having the same priority queue identifier, the message queue system of the type set as shown in Table.

表一 Table I

故基站侧预先设置的每个短时隙寻呼消息队列具有以下标识:优先级标识、时隙周期,以及时隙队列号。 Each paging slot message short side of the base station set in advance so that the queue has the following identification: priority identification, slot cycle, and the time slot queue number.

步骤102:系统将接收到的短时隙寻呼消息根据短时隙寻呼消息标识保存到相应的消息队列中。 Step 102: The system stores the received short message paging slot to save the message queue in accordance with the short slot paging message identifier.

基站侧接收到的每条短时隙寻呼消息具有以下标识:优先级标识、时隙周期、发送时隙标识(PGSLOT),以及QPCH信息标识。 Each short slot paging message to the base station side has received the following identification: priority identification, slot cycle, identifying a transmission slot (PGSLOT), and information identifying the QPCH. 其中,该消息的发送时隙标识(PGSLOT)由系统根据接收该寻呼消息的MS的电子序列号/ 国际移动台标识(ESN/IMSI)计算得出。 Wherein, the message transmission slot identify (PGSLOT) is calculated by the system in accordance with an electronic serial number received in the paging message of the MS / international mobile station identity (ESN / IMSI).

基站接收到基站控制器(BSC)发来的带短时隙标识的短时隙寻呼消息后,根据短时隙寻呼消息的优先级标识确定该消息属于高优先级消息还是属于低优先级消息。 After the base station receives a base station controller (BSC) is sent with a short slot paging message short slot identifier, identifying the short slot according to the priority of the message determines that the paging message is a high priority or a low priority message messages.

对于具有相同优先级标识的短时隙寻呼消息,系统查找对应消息队列保存该消息的过程如图2所示:步骤201:系统判断该短时隙寻呼消息的时隙周期。 Short slot for paging messages with the same priority identification, the system searches the stored message corresponding to the message queue of the process shown in Figure 2: Step 201: The system determines the short slot cycle paging message slot. 本实施例中,短时隙寻呼消息的时隙周期为80ms、 160ms、 320ms和640ms。 In this embodiment, the paging slot message short slot period is 80ms, 160ms, 320ms and 640ms. 若该消息的时隙周期为80ms,执行步骤202;若该消息的时隙周期为160ms,执行步骤203; 若该消息的时隙周期为320ms,执行步骤204;若该消息的时隙周期为640ms , 执行步骤205。 If the message is a slot cycle 80ms, step 202 is performed; if the message slot cycle is 160ms, step 203 is performed; if the message slot cycle is 320ms, perform step 204; slot cycle if the message is 640ms, step 205 is executed.

步骤202:根据公式(1),系统判断该短时隙寻呼消息的PGSLOT, 将满足公式(1)所述关系的短时隙寻呼消息保存到具有相应时隙队列号的短时隙寻呼消息队列中。 Step 202: According to the formula (1), the system determines the short slot PGSLOT paging message, the paging message satisfies a short slot (1) of the relationship saved to the short slot having a formula corresponding time slot queue number to find call message queue. 公式(1)如下: Equation (1) as follows:

时隙队列号-PGSLOTmod (消息时隙周期/系统单位时隙长)(1) Slot queue No. -PGSLOTmod (message slot cycle / system unit slot length) (1)

时隙周期为80ms的短时隙寻呼消息队列只有一个,其时隙队列号为0, 故具有相同优先级标识的80ms短时隙寻呼消息都保存在该队列中。 Short slot cycle is 80ms paging slot is only a message queue, which queue slot number is 0, it has the same priority identification short slot 80ms paging messages stored in the queue.

步骤203、 204和205执行和步骤202相类似的操作:步骤203中,时隙周期为160ms的短时隙寻呼消息队列有两个,时隙队列号分别为0和1。 Step 203, 202 and 204 operate similar to 205 and performs steps: Step 203, the slot cycle of 160ms of the short slot has two paging message queue, the queue slot numbers 0 and 1, respectively. 步骤204中,时隙周期为320ms的短时隙寻呼消息队列有四个,时隙队列号为0~3。 In step 204, a short slot cycle of 320ms paging message queue has four slots, slot queue number from 0 to 3. 步骤205中,时隙周期为640ms的短时隙寻呼消息队列有八个, 时隙队列号为0~7。 In step 205, a short slot cycle of 640ms paging message queue has eight time slots, time slot queue number from 0 to 7.

经过上述消息队列的查找,该短时隙寻呼消息保存到相应的消息队列中等待发送。 After the above-described lookup message queue, the stored short message to the corresponding paging slot message queue waiting to be sent.

上述过程是依次按照短时隙寻呼消息的优先级标识、时隙周期,以及发送时隙标识确定该消息的保存队列的过程。 The above process is sequentially identified according to the priority of the short message paging slot, slot cycle, and a transmission time slot identifier determination process to save the message queue. 确定该消息的保存队列的过程还可以依次按照时隙周期、时隙队列号,以及优先级标识的顺序进行。 Determining the message queue may also save process sequentially in the order of time slot period, a slot number queue, and a priority identifier.

步骤103:系统根据系统时隙号和短时隙寻呼消息队列标识确定当前时隙需要处理的消息队列,并按先后顺序从消息队列中取消息发送。 Step 103: The system message queue to determine the current time slot in need of treatment system according to a slot number and a short message queue identifier paging slot, according to the order taken from the message transmit queue.

系统在系统时隙N收到时隙触发请求后,先确定需要在系统时隙N处理的消息队列。 N slot system after the system receives the trigger request slot, the first processing system determines that N time slot message queue. 在本发明的实施例中,系统确定需要在系统时隙N处理的消息队列的过程,即消息队列的调度过程如下: In an embodiment of the present invention, the system needs to determine the N processing procedure in the system message queue time slot, i.e., the message queue scheduling process is as follows:

ii假设系统单位时隙长为80ms,基站根据消息队列的时隙队列号确定某系统时隙N被调度的短时隙消息队列,满足公式(2)的消息队列在某系统时隙N被调度。 ii assumed that the system unit slot length of 80ms, the base station system determines a scheduled time slot N are short slot message queue according to the message queue of the time slot queue number, satisfying the formula (2) in the message queue to be scheduled in a system slot N . 公式(2)如下: Equation (2) as follows:

(N-消息队列的时隙队列号)mod(消息的时隙周期/系统单位时隙长)==0 (2) 系统在当前时隙确定需要被处理的消息队列时,可以通过遍历所有的短时隙寻呼消息队列的方式,查找满足公式(2)的短时隙寻呼消息队列。 (N- message queue slot queue number) mod (slot cycle message / system unit slot length) == 0 (2) while the current slot identifying the message queue to be processed, by traversing all short slot mode paging message queue, find satisfying the formula (2) is short slot paging message queue. 系统也可以用表格的方式存储在某时隙需要被处理的消息队列的时隙队列号, 在某时隙到来时,通过查表的方式确定当前时隙需要被处理的消息队列。 The system can also use the message storage table to be processed in the queue number of a queue timeslots in a time slot arrives, determines the current time slot the message queue to be processed by table lookup. 由于系统对短时隙消息队列的调度具有周期性,故表格中只需记录系统一个时隙周期内每个时隙需要被处理的消息队列的时隙队列号。 Since the system has a periodic short message scheduling queue slots, so that the table only message recording system within a time slot period of each time slot to be processed in the queue slot queue number.

对于系统时隙N而言,系统根据公式(3)确定该系统时隙N在系统一个时隙周期内的对应时隙。 For N slot system, the system (3) for determining the system time slot corresponding to N time slots within one time slot period of the system according to the formula. 公式(3)如下: Equation (3) as follows:

对应时隙=(系统时隙N ) mod (短时隙消息的最长时隙周期/系统单位时隙长)(3 ) 对于80ms短时隙寻呼消息队列而言,只有一个时隙队列号为0的消息队列,故该队列在系统一个时隙周期的每个对应时隙都需要被调度。 = Corresponding time slot (slot system N) mod (the longest slot cycle of short slot message / system unit slot length) (3) for the 80ms paging slot message short queue, queue number only one time slot 0 message queue, the queue so that a slot cycle corresponding to each time slot need to be scheduled in the system. 时隙周期为160ms的短时隙寻呼消息队列有时隙队列号为0和1的两个消息队列, 故这两个消息队列在系统一个时隙周期内被轮流调度。 Slot cycle paging slot is 160ms short message queue has two slot queue No. 1 and 0 the message queue, the message queue so that two turns are scheduled in a slot cycle system. 时隙周期为320ms 的短时隙寻呼消息有时隙队列号为0~3的四个消息队列,故这四个消息队列在系统一个时隙周期内被循环调度。 Slot cycle for the paging slot message short 320ms slot queue number has four message queues 0 to 3, so that four message queues in round-robin scheduling is a slot cycle system. 时隙周期为640ms的短时隙寻呼消息有时隙队列号为0〜7的八个消息队列,故这八个消息队列在系统一个时隙周期内被循环调度。 Slot cycle for the paging slot message short 640ms slot queue No. 0 to 7 have eight message queue, the message queue so that eight slot period in a circulating system is scheduled.

表二是具有相同优先级标识的时隙寻呼消息队列调度表。 Table II is the slot schedule paging message queue with the same priority identifier. 表二中的系统时隙指的是系统一个时隙周期内的每个对应时隙。 Table II refers to the system time slot corresponding to each time slot within a slot cycle system.

在取消息发送时,对于可以在当前时隙调度的消息队列,消息队列处理 When taking messaging, message to be scheduled in the current time slot queue, the message queue processing

的先后顺序如下:对于时隙周期相同的消息队列,系统判断其优先级标识, 优先级标识为高的消息队列中的消息先被发送,优先级标识为低的消息队列中的消息后被发送。 The sequence is as follows: for the same slot period the message queue, the system determines the priority identifier, identified as a high priority message queue to be sent first message, identified as low priority message is transmitted after the message queue .

对于具有相同优先级标识的消息队列,系统判断其时隙周期。 For the message queue with the same priority identifier, the system determines its slot cycle. 时隙周期短的消息队列中的消息先被发送,时隙周期长的消息队列中的消息后被发送。 Short slot cycle after sending the message queue to be sent first message, the message slot cycle length in a message queue. 时隙周期短的寻呼消息对应的移动终端接收周期也短,故先发送时隙周期短的寻呼消息,可以缩短与该消息对应移动终端的等待时间。 Short slot cycle paging message corresponding to the mobile terminal reception cycle is short, so the first transmission of short slot cycle paging message, the waiting time can be shortened corresponding to the mobile terminal with the message.

如表二所示,假设系统一个时隙周期内的某对应时隙为5时隙,则系统首先查找并发送80ms第0时隙寻呼消息队列中的寻呼消息,其次是发送160ms第1时隙寻呼消息队列中的寻呼消息,再次是发送320ms第1时隙寻呼消息队列中的寻呼消息,最后发送640ms第5时隙寻呼消息队列中的寻呼消息。 As shown in Table II, a corresponding time slot in a slot period is assumed that the system 5 slots, then the system first sends a paging message to find and 80ms paging slot 0 message queue, followed by a first transmission 160ms paging message paging message queue slot, a paging message is again sent 320ms first time slot of the paging message queue, and finally transmits a paging message 640ms fifth slot paging message queue.

在现有标准中,基站侧定义有快速寻呼信道(QPCH) , QPCH信道和发送寻呼消息的信道配合使用,能提高移动终端接收寻呼消息的效率。 In the existing standard, the base station side is defined with a Quick Paging Channel (QPCH), QPCH channel and transmitting a paging message channel with the use, improve the efficiency of the mobile terminal receives a paging message. QPCH 信道上发送的消息用于提前通知移动终端:在系统某个时隙,基站侧有寻呼消息发送给该移动终端,从而确保移动终端在指定时隙打开接收装置,接收寻呼消息。 QPCH messages transmitted on the channel for notifying the mobile terminal in advance: paging message sent to the mobile terminal in the system a certain time slot, the base station side, the receiving opening to ensure that the mobile terminal apparatus in time slot designated to receive the paging message. 对于其它本该在该时隙打开接收装置监听的移动终端而言,由于能够从QPCH发送的消息中确知该时隙寻呼消息不是发送给自己的,故其它移动终端在该时隙可以停止监听,节省了其它移动终端的监听耗电。 For the opening of this other receiving device in the time slot listening mobile terminal, it is possible to ascertain that the paging slot message from a message transmitted QPCH not addressed to itself, so that other mobile terminals may stop in the slot listening, listening saving power of other mobile terminals.

因为不是所有的短时隙寻呼消息都需要同QPCH信道消息配合发送,所以,系统只对需要QPCH信道配合发送监听指示给移动终端的短时隙寻呼消息,在该寻呼消息加上QPCH信息标识。 Because not all short timeslots requires a paging message sent with the message with the QPCH channel, so that the transmission system only with the indication of the need to listen to the short slot QPCH paging channel message for the mobile terminal, the paging message plus the QPCH information logo.

对于带有QPCH信息标识的消息,基站在该条消息发送前120ms为该消息发送寻呼指示符(PI)给QPCH信道。 For the QPCH message with information identifying the base station transmits 120ms paging indicator (PI) for the message before the message is sent to the article QPCH channel. 该消息被发送前,基站需要确认该条消息是否已经发送寻呼指示符(PI)给QPCH信道。 Before the message is sent, the base station need to confirm whether the message has been transmitted paging indicator strip (PI) to the QPCH channel. 如果PI已发送, 则这条消息可以在信道中发送;如果PI没有发送,则这条消息在当前时隙不能发送。 If the PI is sent, then this message may be sent in the channel; If the PI is not transmitted, this message can not be sent in the current slot. 对于这种不能发送的情况,该消息应在原队列中等待,直到该消息已经发送PI给QPCH信道,才能在以后符合该消息发送时隙条件的时隙发送。 This is not the case of transmission, the original message should wait in queue until the message has been sent to the PI QPCH channel in order to meet the time slot after the transmission slot of the message transmission conditions.

由上述实施例可见,本发明的这种短时隙寻呼消息的调度方法充分考虑到寻呼消息快速收发的需求,在调度时优先发送时隙周期短的短时隙寻呼消息,使移动终端能及时地响应寻呼,提高了通信的实时性。 Seen from the above embodiment, such a short slot scheduling method of the present invention, the paging message is a paging message fully into account the needs of rapid transmission and reception, transmission priority short slot cycle paging slot message short scheduling, mobile paging terminal responsive to a timely manner, improving the communication in real time.
