Description
本发明涉及通信技术领域,特别涉及一种接入网络的方法及接入设备。The present invention relates to the field of communications technologies, and in particular, to a method for accessing a network and an access device.
下一代移动通信技术的时代即将到来。为了最大程度地利用现有的通信系统,例如长期演进(Long Term Evolution,LTE)通信系统,支持下一代移动通信技术的终端设备可以通过LTE系统的空口接入网络。LTE系统的基站与终端之间采用空口进行通信,因此该空口可以简称为LTE空口,或者,LTE系统的空口。The era of next-generation mobile communication technology is coming. In order to make maximum use of an existing communication system, such as a Long Term Evolution (LTE) communication system, a terminal device supporting the next generation mobile communication technology can access the network through an air interface of the LTE system. The air interface of the LTE system is used for communication between the base station and the terminal. Therefore, the air interface can be simply referred to as an LTE air interface or an air interface of the LTE system.
然而,支持下一代移动通信技术的终端设备与支持LTE技术的终端设备都通过LTE系统的空口接入网络,将会导致LTE系统的空口负载较高,进而导致多个终端设备通过LTE系统的空口接入网络时,LTE系统的随机接入信道(RandomAccess Channel,RACH)会出现较多的冲突。However, the terminal equipment supporting the next-generation mobile communication technology and the terminal equipment supporting the LTE technology are all connected to the network through the air interface of the LTE system, which will result in a high air interface load of the LTE system, which in turn causes multiple terminal devices to pass through the air interface of the LTE system. When accessing the network, there are more conflicts in the random access channel (RACH) of the LTE system.
为了减轻LTE系统的空口负载,减少随机接入信道的冲突,可以设置独立的下一代移动通信系统的空口,终端设备通过该空口接入下一代移动通信系统的基站,从而接入网络。但考虑到下一代移动通信系统的基站可能无法独立工作,即需要借助LTE基站的高层才能工作。而LTE系统中,随机接入冲突是通过读取无线资源控制(Radio Resource Control,RRC)层的内容解决的。在这种特定的机制下,终端设备如何通过下一代移动通信系统的空口接入网络的问题亟待解决。In order to reduce the air interface load of the LTE system and reduce the collision of the random access channel, an air interface of the independent next-generation mobile communication system can be set, and the terminal device accesses the base station of the next-generation mobile communication system through the air interface, thereby accessing the network. However, considering that the base station of the next-generation mobile communication system may not work independently, it needs to work with the upper layer of the LTE base station. In the LTE system, the random access conflict is solved by reading the content of the Radio Resource Control (RRC) layer. Under this particular mechanism, the problem of how terminal devices access the network through the air interface of the next generation mobile communication system needs to be solved.

The upper layer of the seven-layer protocol of the LTE system, such as the layer, only
Layer 1 or Layer 2, for example: Physical Layer (PHY) Link Control (Radio Link Control, RLC) layer.
本发明实施例中所述的下一代移动通信系统的接口是指采用下一代移动通信技术建立,位于终端设备和下一代移动通信系统的基站设备之间的空口。例如,本发明实施例中,将终端设备与5G基站设备之间的空口称为5G空口,或5G系统的空口。The interface of the next-generation mobile communication system described in the embodiment of the present invention refers to an air interface established between the terminal device and the base station device of the next-generation mobile communication system by using the next-generation mobile communication technology. For example, in the embodiment of the present invention, the air interface between the terminal device and the 5G base station device is referred to as a 5G air interface, or an air interface of the 5G system.
在本发明实施例中,相对于LTE中的七层协议,将5G空口所使用的协议称为低层协议,5G空口使用的协议称为高层协议,如前举例的NAS、RRC、IP以及PDCP等协议。In the embodiment of the present invention, the protocol used by the 5G air interface is referred to as a lower layer protocol, and the protocol used by the 5G air interface is referred to as a higher layer protocol, such as NAS, RRC, IP, and PDCP, as in the previous example. protocol.

In the embodiment of the present invention, the air interface of the 5G mobile communication system is referred to as a 5G air interface.
可以通过如下方式利用5G空口:终端设备通过LTE空口接入,之后通过双连接(Dual Connectivity,DC)或者载波聚合(Carrier Aggregation,CA)的方式利用5G空口。基于以上终端设备通过LTE空口接入网络,UE的控制面(Control Plane,CP)和用户面(User Plane,UP)通过双连接(Dual Connectivity,DC)的方式同时利用LTE和5G空口。图1a至图1c是三个协议层示意图,其中左侧为LTE网络的协议示意,右侧为5G网络的协议示意,左侧LTE中从NAS到UE的粗体实线为控制面示意,跨LTE和5G的粗虚线为用户面示意。在LTE侧还包含有RRC和IP层。5G和LTE锚点采用X5接口建立连接。The 5G air interface can be utilized in the following manner: the terminal device accesses through the LTE air interface, and then utilizes the 5G air interface by means of dual connectivity (DC) or carrier aggregation (CA). Based on the above terminal equipment accessing the network through the LTE air interface, the Control Plane (CP) and the User Plane (UP) of the UE simultaneously utilize LTE and 5G air interfaces by means of dual connectivity (DC). 1a to 1c are schematic diagrams of three protocol layers, where the left side is a protocol diagram of an LTE network, and the right side is a protocol of a 5G network. The bold solid line from the NAS to the UE in the left LTE is a control plane. The thick dotted lines of LTE and 5G are indicated by the user plane. The RRC and IP layers are also included on the LTE side. The 5G and LTE anchors use the X5 interface to establish a connection.
如图1a所示,UE通过LTE接入,控制面(Control Plane,CP)保留在LTE。之后用户面(User Plane,UP)通过DC的方式同时利用LTE和5G空口,即用户面锚点在LTE分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层。之后一部分数据经过LTE PDCP层之后,继续通过LTE RLC(Radio Link Control,无线链路控制)/MAC/PHY(Physical,物理)层,即通过LTE空口发给UE。另一部分数据经过LTE PDCP层之后,通过5G空口的
RLC/MAC/PHY层,即通过5G空口发给UE。As shown in FIG. 1a, the UE accesses through LTE, and the Control Plane (CP) remains in LTE. Then, the User Plane (UP) utilizes both LTE and 5G air interfaces through DC, that is, the user plane anchor is in the LTE Packet Data Convergence Protocol (PDCP) layer. After a part of the data passes through the LTE PDCP layer, the LTE RLC (Radio Link Control)/MAC/PHY (Physical) layer is transmitted to the UE through the LTE air interface. Another part of the data passes through the LTE PDCP layer and passes through the 5G air interface.
The RLC/MAC/PHY layer is sent to the UE through the 5G air interface.

Then, the user plane utilizes LTE and 5G air interfaces simultaneously through the CA, that is, the user plane anchor is in the LTE Medium Access Control (MAC) layer. After a part of the data passes through the LTE PDCP layer, it continues to pass through the LTE RLC/MAC/PHY layer, that is, it is sent to the UE through the LTE air interface. After the other part of the data passes through the LTE PDCP layer, it is sent to the UE through the MAC/PHY layer of the 5G air interface, that is, through the 5G air interface.
如图1c所示,UE通过LTE接入,控制面保留在LTE。之后用户面通过CA的方式同时利用LTE和5G空口,即用户面锚点在LTE媒体接入控制(Medium Access Control,MAC)层。之后一部分数据经过LTE PDCP层之后,继续通过LTE RLC/MAC/PHY层,即通过LTE空口发给UE。另一部分数据经过LTE PDCP层之后,通过5G空口的PHY层,即通过5G空口发给UE。As shown in FIG. 1c, the UE accesses through LTE, and the control plane remains in LTE. Then, the user plane utilizes the LTE and the 5G air interface through the CA mode, that is, the user plane anchor point is in the LTE Medium Access Control (MAC) layer. After a part of the data passes through the LTE PDCP layer, it continues to pass through the LTE RLC/MAC/PHY layer, that is, it is sent to the UE through the LTE air interface. After another part of the data passes through the LTE PDCP layer, it is sent to the UE through the PHY layer of the 5G air interface, that is, through the 5G air interface.
如图2a所示为本发明实施例系统架构示意图,在该系统架构的示意中5G空口只有底层协议不使用高层协议,例如:在DC方式下只有RLC、MAC以及PHY,CA方式下只有MAC和PHY,或者,只有PHY。5G空口和LTE空口可以共享单非接入层(singleNAS)和单无线资源控制(singleRRC)。其中SingleNAS用于传输UE和核心网之间的非接入层(Non-Access Stratum,NAS)信令。而singleRRC用于传输用户设备(User Equipment,UE)和演进型基站(E-UTRAN Node B,eNB)之间的RRC消息。图2a中所示的UE即终端设备。2A is a schematic diagram of a system architecture according to an embodiment of the present invention. In the schematic diagram of the system architecture, only the underlying protocol does not use a high-level protocol, for example, only the RLC, the MAC, and the PHY in the DC mode, and only the MAC in the CA mode. PHY, or, only PHY. The 5G air interface and the LTE air interface can share a single non-access stratum (singleNAS) and a single radio resource control (single RRC). The SingleNAS is used to transmit Non-Access Stratum (NAS) signaling between the UE and the core network. The single RRC is used to transmit an RRC message between a User Equipment (UE) and an E-UTRAN Node B (eNB). The UE shown in Fig. 2a is a terminal device.

图2b至图2d是三个协议层示意图,其中左侧为LTE网络的协议示意,右侧为5G网络的协议示意,LTE中从NAS到UE的粗体实线为控制面示意,跨LTE和5G的粗虚线为用户面示意。在LTE侧还包含有RRC和IP层。5G和LTE锚点的层采用X5接口建立连接。Figure 2b to Figure 2d are schematic diagrams of three protocol layers, where the left side is the protocol of the LTE network, and the right side is the protocol of the 5G network. The bold solid line from the NAS to the UE in LTE is the control plane, cross-LTE and The thick dashed line of 5G is indicated by the user plane. The RRC and IP layers are also included on the LTE side. The layers of the 5G and LTE anchors are connected using the X5 interface.
图2b中,DC方式下UE利用5G空口接入。在CP和UP面锚点在LTE PDCP层。5G空口使用RLC、MAC和PHY层协议。即CP面(SingleNAS,SingleRRC层)通过LTE PDCP之后,经过5G空口的RLC、MAC和PHY层发送给UE。而UP面(IP层)通过LTE PDCP之后,经过5G空口RLC、MAC和PHY层发送给UE。In Figure 2b, the UE accesses the 5G air interface in the DC mode. The CP and UP plane anchors are in the LTE PDCP layer. The 5G air interface uses the RLC, MAC, and PHY layer protocols. That is, the CP surface (SingleNAS, SingleRRC layer) is transmitted to the UE through the RLC, MAC, and PHY layers of the 5G air interface after passing the LTE PDCP. After the UP plane (IP layer) passes the LTE PDCP, it is sent to the UE through the 5G air interface RLC, MAC, and PHY layers.
图2c中,CA方式下UE利用5G空口接入。CP和UP面锚点在LTE的MAC层。5G空口使用MAC和PHY层协议。即CP面(SingleNAS,SingleRRC层)通过LTE的PDCP、RLC以及MAC之后,经过5G空口MAC和PHY层发送给UE。而UP面(IP层)通过LTE的PDCP、RLC和MAC之后,经过5G空口MAC和PHY层发送给UE。In Figure 2c, the UE accesses the 5G air interface in the CA mode. The CP and UP plane anchors are at the MAC layer of LTE. The 5G air interface uses the MAC and PHY layer protocols. That is, the CP surface (SingleNAS, SingleRRC layer) is transmitted to the UE through the 5G air interface MAC and PHY layer after passing through the PDCP, RLC, and MAC of the LTE. The UP plane (IP layer) is sent to the UE through the 5G air interface MAC and PHY layer after passing through the PDCP, RLC, and MAC of the LTE.
图2d中,CA方式下UE利用5G空口接入。CP和UP面锚点在LTE的MAC层。5G空口使用MAC和PHY层协议。即CP面(SingleNAS,SingleRRC层)通过LTE的PDCP、RLC和MAC之后,经过5G空口的PHY层发送给UE。而UP面(IP层)通过LTE的PDCP、RLC和MAC之后,经过5G空口PHY层发送给UE。In Figure 2d, the UE accesses the 5G air interface in the CA mode. The CP and UP plane anchors are at the MAC layer of LTE. The 5G air interface uses the MAC and PHY layer protocols. That is, the CP surface (SingleNAS, SingleRRC layer) is transmitted to the UE through the PHY layer of the 5G air interface after passing through the PDCP, RLC, and MAC of the LTE. The UP plane (IP layer) is sent to the UE through the 5G air interface PHY layer after passing through the PDCP, RLC, and MAC of the LTE.
在所述图2a所示的新架构下,由于5G空口只有底层,而高层(例如DC方式下的PDCP和RRC层)在LTE。所以随机接入涉及UE、5G eNB以及LTE eNB的信令交互。Msg1,3分别是发给5G eNB还是LTE eNB,以及UE通过什么方式获知随机接入成功,都需要解决。
In the new architecture shown in FIG. 2a, since the 5G air interface has only the bottom layer, the upper layer (for example, the PDCP and RRC layers in the DC mode) is in the LTE. Therefore, random access involves signaling interaction between the UE, the 5G eNB, and the LTE eNB. Whether Msg1, 3 is sent to the 5G eNB or the LTE eNB, respectively, and how the UE learns that the random access is successful needs to be solved.
UE选择5G空口接入,有如下几种可能:The UE selects 5G air interface access, which has the following possibilities:
1、只支持5G的单模UE,只能通过5G空口接入。此种情况下,UE虽然是单模UE,但还是具备支持LTE高层协议的能力。1. Only 5G single-mode UEs can be accessed through 5G air interfaces. In this case, although the UE is a single-mode UE, it still has the ability to support LTE high-level protocols.
2、LTE eNB广播指示UE去其他制式驻留,可能是1bit指示UE通过5G空口接入,也可能是指示5G空口小区标识,例如物理小区标识(Physical layer Cell Identity,PCI),或者频点+PCI等,导致UE被指示通过5G空口接入。2. The LTE eNB broadcasts the indication that the UE is camped on other systems. The 1bit indicates that the UE accesses the 5G air interface, and may also indicate the 5G air interface cell identifier, such as the physical layer cell identity (PCI), or the frequency point + PCI or the like causes the UE to be instructed to access through the 5G air interface.
3、5G eNB和LTE eNB分别广播其负载信息(可能还有时延、backhaul等信息),UE根据广播信息选择通过5G空口接入。3. The 5G eNB and the LTE eNB respectively broadcast their load information (and possibly delay, backhaul, etc.), and the UE selects to access through the 5G air interface according to the broadcast information.
基于以上介绍,本发明实施例提供了一种接入网络的方法,在本实施例中,第一接入设备可以是支持5G空口协议的接入设备,即5G移动通信系统中的接入设备例如图2a中所示的5G eNB,第二接入设备可以是4G系统中的接入设备,例如LTE系统中的eNB。本发明实施例对第一接入设备的类型不做特别限定,也可以是其他未来演进通信中的接入设备。Based on the above description, the embodiment of the present invention provides a method for accessing a network. In this embodiment, the first access device may be an access device supporting a 5G air interface protocol, that is, an access device in a 5G mobile communication system. For example, the 5G eNB shown in FIG. 2a, the second access device may be an access device in a 4G system, such as an eNB in an LTE system. The type of the first access device is not specifically limited in the embodiment of the present invention, and may also be an access device in other future evolved communications.
如图3所示,该方法包括:As shown in FIG. 3, the method includes:
301:终端设备向第一接入设备发送第一消息;301: The terminal device sends a first message to the first access device.
所述第一消息用于请求接入网络的消息,所述第一消息中携带第一标识信息,所述第一标识信息用于确定是否允许所述终端设备接入网络,其中,所述第一接入设备不支持高层协议;The first message is used to request a message for accessing the network, where the first message carries the first identifier information, where the first identifier information is used to determine whether the terminal device is allowed to access the network, where the An access device does not support high layer protocols;
在本实施例中高层协议可以参考前述实施例中关于高层协议的定义。In the present embodiment, the higher layer protocol may refer to the definition of the higher layer protocol in the foregoing embodiment.
在本实施例中,基于第一标识信息的用途,可以参考随机接入技术中标识信息的使用,该第一标识信息临时移动用户标识(Serving-Temporary Mobile Subscriber Identity,S-TMSI)、随机值(Randomvalue)等。In this embodiment, based on the use of the first identifier information, reference may be made to the use of the identifier information in the random access technology, the first identifier information, the Serving-Temporary Mobile Subscriber Identity (S-TMSI), and the random value. (Randomvalue) and so on.
在本实施例中“第一”和“第二”只是为了区分两个相同技术术语,不应理解为具有其他技术含义。其中“第一标识信息”是终端设备向上行发送的标识信息,“第二标识信息”是终端设备下行接收的标识信息。In the present embodiment, "first" and "second" are merely used to distinguish two identical technical terms, and should not be construed as having other technical meanings. The “first identification information” is the identification information that is sent by the terminal device to the uplink, and the “second identification information” is the identification information that is received by the terminal device.
接入设备是指位于接入网的设备,通常来说可以是基站或者接入点(Access Point,AP)等。An access device is a device located on an access network, and may be a base station or an access point (AP).
302:第一接入设备接收来自终端设备发送的第一消息,若所述终端设备被允许接入网络,所述第一接入设备向所述终端设备发送第二消息,所述第二
消息为所述第一消息的响应消息且所述第二消息携带第二标识信息,其中,所述第二标识信息与所述第一标识信息相同。302: The first access device receives the first message sent by the terminal device, and if the terminal device is allowed to access the network, the first access device sends a second message to the terminal device, where the second
The message is a response message of the first message, and the second message carries second identity information, where the second identity information is the same as the first identity information.
终端设备是否被允许接入网络,通常是通过第一标识信息确定的,具体可以是:如果多个不同的终端在相同时频资源上发送第一消息,网络侧通过所述第一标识信息进行区分。一种可能的情况是网络侧只能解析特定用户的第一消息并获得第一标识信息,从而将第二标识信息设置成第一标识信息发给终端。另一种可能的情况是,网络侧可能可以解析多个用户的第一消息并获取相应的第一标识信息,网络侧选择特定的第一标识信息,并将第二标识信息设置成第一标识信息发给终端。Whether the terminal device is allowed to access the network, which is determined by the first identifier information, and specifically, if the multiple different terminals send the first message on the same time-frequency resource, the network side performs the first identifier information. distinguish. One possible case is that the network side can only parse the first message of the specific user and obtain the first identification information, so that the second identification information is set to the first identification information and sent to the terminal. Another possible situation is that the network side may parse the first message of multiple users and obtain corresponding first identification information, and the network side selects specific first identification information, and sets the second identification information to the first identifier. Information is sent to the terminal.
303:终端设备接收所述第一接入设备发送的第二消息,解析所述第二消息获得所述第二标识信息,若所述第一标识信息与所述第二标识信息相同,确定接入网络成功。如果在接收第二消息的时间段内没有接收到第二消息,或者接收到了第二消息但是第二标识信息与第一标识信息不同,均可以确定接入网络失败,此时可以重新发送第一消息携带第一标识信息。303: The terminal device receives the second message sent by the first access device, and parses the second message to obtain the second identifier information. If the first identifier information is the same as the second identifier information, determining Successfully entered the network. If the second message is not received within the time period of receiving the second message, or the second message is received but the second identification information is different from the first identification information, the access network may be determined to be failed, and the first time may be resent. The message carries the first identification information.
本发明实施例的终端设备通过第一接入设备接入网络,在接入网络的过程中终端设备的控制面使用与第一接入设备之间的空口,其中,第一接入设备不支持高层协议,例如:第一接入设备是采用5G通信技术的接入设备;因此本发明实施例的终端设备在接入网络的过程中可以不使用LTE空口,避免了所有终端设备均使用LTE空口接入网络造成LTE空口负载过高的问题;因此,可以降低LTE空口的负载,从而减少LTE网络的随机接入信道冲突。The terminal device of the embodiment of the present invention accesses the network through the first access device, and the control plane of the terminal device uses an air interface with the first access device in the process of accessing the network, where the first access device does not support The high-level protocol, for example, the first access device is an access device that uses the 5G communication technology; therefore, the terminal device in the embodiment of the present invention can not use the LTE air interface in the process of accessing the network, and avoids that all terminal devices use the LTE air interface. The access network causes the LTE air interface to be overloaded. Therefore, the load on the LTE air interface can be reduced, thereby reducing the random access channel conflict of the LTE network.
在一个可能的实现方式中,在随机接入之后可以进行数据传输,所述方法还包括:所述第一接入设备建立与第二接入设备之间的通信接口,所述第二接入设备支持高层协议。In a possible implementation, the data transmission may be performed after the random access, the method further includes: the first access device establishes a communication interface with the second access device, and the second access The device supports high level protocols.
在上述通信接口建立以后,第一接入设备可以将来自终端的上行数据通过上述通信接口发送给第二接入设备,还可以通过上述通信接口接收第二接入设备发送的发往上述终端设备的下行数据。通信接口建立过程可以由第一接入设备发起也可以由第二接入设备发起,对此本发明实施例不作限制。After the communication interface is established, the first access device may send the uplink data from the terminal to the second access device by using the foregoing communication interface, and may also receive, by using the communication interface, the second access device and send the foregoing to the terminal device. Downstream data. The communication interface establishment process may be initiated by the first access device or by the second access device, which is not limited in this embodiment of the present invention.
在以上步骤302中“所述终端设备被允许接入网络”,可以由第一接入设备做出决策,也可以是由第二接入设备作出决策,以下分别就这两种方式进行
具体说明:In the above step 302, “the terminal device is allowed to access the network”, the first access device may make a decision, or the second access device may make a decision, and the following two manners are respectively performed.
Specific instructions:
一、由第一接入设备决策是否允许终端设备接入网络:1. The first access device determines whether the terminal device is allowed to access the network:
在此种情况下,由于第一接入设备并不支持高层协议,因此第一标识信息位于第一接入设备所支持的协议层,第一接入设备则可以从第一消息获得第一标识信息。In this case, since the first access device does not support the upper layer protocol, the first identifier information is located at a protocol layer supported by the first access device, and the first access device may obtain the first identifier from the first message. information.
作为一个举例,所述第一消息为无线资源控制RRC连接请求消息;所述第二消息为RRC连接建立消息。采用已有的消息可以兼容LTE系统。As an example, the first message is a radio resource control RRC connection request message; and the second message is an RRC connection setup message. The existing message can be used to be compatible with the LTE system.
那么此种情况下,所述第一标识信息包括在所述RRC连接请求消息的外层空口协议层中。所述RRC连接请求消息本身仍然可以是4G协议中规定的RRC连接请求消息,在其外层增加了新的协议层,因此“外层空口协议层”是第一接入设备所能支持的协议层;Then in this case, the first identifier information is included in an outer air interface protocol layer of the RRC connection request message. The RRC connection request message itself may still be an RRC connection request message specified in the 4G protocol, and a new protocol layer is added to the outer layer, so the "outer air interface protocol layer" is a protocol that the first access device can support. Floor;
基于第一接入设备已经能获得第一标识信息,那么步骤302中的所述若所述终端设备被允许接入网络,所述第一接入设备向所述终端设备发送第二消息包括:If the first access device can obtain the first identification information, if the terminal device is allowed to access the network in the step 302, the sending, by the first access device, the second message to the terminal device includes:
所述第一接入设备解析所述外层空口协议层,获取所述第一标识信息;The first access device parses the outer air interface protocol layer to obtain the first identifier information;
所述第一接入设备确定允许所述终端设备接入网络后,向所述终端设备发送第二消息。After the first access device determines that the terminal device is allowed to access the network, the second access message is sent to the terminal device.
更具体地,在本实施例中所述第二标识信息包括在所述RRC连接建立消息的外层空口协议层中。More specifically, in the embodiment, the second identifier information is included in an outer air interface protocol layer of the RRC connection setup message.
二、由第二接入设备决策是否允许终端设备接入网络:2. The second access device determines whether the terminal device is allowed to access the network:
在此种情况下,第一标识信息位于第一接入设备所不支持的协议层,第一接入设备无法获得第一标识信息。In this case, the first identifier information is located in a protocol layer that is not supported by the first access device, and the first access device cannot obtain the first identifier information.
作为一个举例,所述第一消息为无线资源控制RRC连接请求消息;所述第二消息为RRC连接建立消息。采用已有的消息可以兼容LTE系统。As an example, the first message is a radio resource control RRC connection request message; and the second message is an RRC connection setup message. The existing message can be used to be compatible with the LTE system.
那么此种情况下,所述第一标识信息包括在所述RRC连接请求消息中。那么此种情况下,第一接入设备可以将第一消息发送给第二接入设备由第二接入设备进行决策,所述方法还包括:Then in this case, the first identification information is included in the RRC connection request message. In this case, the first access device may send the first message to the second access device to perform the decision by the second access device, where the method further includes:
所述第一接入设备向所述第二接入设备发送所述第一消息;Sending, by the first access device, the first message to the second access device;
所述第一接入设备接收所述第二接入设备允许所述终端设备接入网络后
发送的所述第二标识信息。After the first access device receives the second access device, the terminal device is allowed to access the network.
The second identification information sent.
基于本发明实施例的应用场景,第二接入设备可以仅发送第二标识信息,也可以结合LTE网络随机接入的流程中已有的消息携带该第二标识信息,其中后一种方式兼容性较好,具体如下:Based on the application scenario of the embodiment of the present invention, the second access device may only send the second identifier information, and may also carry the second identifier information in combination with the existing information in the process of the random access procedure of the LTE network, where the latter method is compatible. Good sex, as follows:
所述第一接入设备接收所述第二接入设备允许所述终端设备接入网络后发送的所述第二标识信息,包括:The receiving, by the first access device, the second identifier information that is sent by the second access device after the terminal device is allowed to access the network, includes:
所述第一接入设备接收所述第二接入设备允许所述终端设备接入网络后发送的RRC连接建立消息,所述第二标识信息包括在所述RRC连接建立消息中;Receiving, by the first access device, an RRC connection setup message that is sent by the second access device after the terminal device is allowed to access the network, where the second identifier information is included in the RRC connection setup message;
所述第一接入设备向所述终端设备发送第二消息,所述第二消息携带第二标识信息,包括:The first access device sends a second message to the terminal device, where the second message carries the second identifier information, including:
所述第一接入设备将携带所述第二标识信息的RRC连接建立消息发送给所述终端设备。The first access device sends an RRC connection setup message carrying the second identifier information to the terminal device.
在本发明实施例中,基于以上存在两种携带第一标识信息的方式,终端设备如何决策采用何种方式实现,具体可以有如下三种可能性:In the embodiment of the present invention, based on the above two manners of carrying the first identification information, how the terminal device decides to implement the method may have the following three possibilities:
1、由第一接入设备指定,具体如下:所述第一接入设备向所述终端设备广播指示消息,所述指示消息用于指示所述终端设备在RRC连接请求消息的外层空口协议层携带标识信息或者在RRC连接请求消息中携带标识信息。1. The first access device specifies, as follows: the first access device broadcasts an indication message to the terminal device, where the indication message is used to indicate that the terminal device is in an outer air interface protocol of an RRC connection request message. The layer carries the identifier information or carries the identifier information in the RRC connection request message.
2、由第二接入设备指定,具体如下:所述第二接入设备向所述终端设备广播指示消息,所述指示消息用于指示所述终端设备在RRC连接请求消息的外层空口协议层携带标识信息或者在RRC连接请求消息中携带标识信息。2. The second access device specifies, as follows: the second access device broadcasts an indication message to the terminal device, where the indication message is used to indicate that the terminal device is in an outer air interface protocol of an RRC connection request message. The layer carries the identifier information or carries the identifier information in the RRC connection request message.
在以上1和2由接入设备指定的实现方式中,接入设备在指示消息中并不需要指定终端设备发送何种特定的标识信息,因此以上标识信息应当理解为泛指的标识信息,而不是指定必须携带前面实施例记载的第一标识信息。In the foregoing implementation manners of the access device specified by the access device, the access device does not need to specify the specific identifier information sent by the terminal device in the indication message, so the above identifier information should be understood as the general identifier information, and It is not specified that the first identification information described in the previous embodiment must be carried.
3、终端设备自行决策,具体如下:终端设备根据预定规则确定在第一消息的外层空口协议层携带所述第一标识信息或者在第一消息中携带所述第一标识信息,更具体地:终端设备根据预定规则确定在RRC连接请求消息的外层空口协议层携带所述第一标识信息或者在RRC连接请求消息中携带所述第一标识信息。上述预定规则可以是5G协议中规定的,也可以是终端设备依据
第一接入设备是否具备决策是否允许终端设备接入网络的能力确定的,具体采用这种规则可以按需要确定,本实施例对此不予限定。3. The terminal device makes its own decision, as follows: the terminal device determines, according to a predetermined rule, that the first air interface protocol layer of the first message carries the first identifier information or carries the first identifier information in the first message, more specifically The terminal device determines that the first identifier information is carried in the outer air interface protocol layer of the RRC connection request message or the first identifier information is carried in the RRC connection request message according to a predetermined rule. The foregoing predetermined rule may be specified in the 5G protocol, or may be based on the terminal device.
Whether the first access device has the ability to determine whether the terminal device is allowed to access the network is determined, and the specific rule may be determined as needed, which is not limited in this embodiment.
以下提供了三个可选实施例,作为基于以上图2a所示的系统架构下,UE的随机接入流程。Three alternative embodiments are provided below as a random access procedure for the UE based on the system architecture shown in Figure 2a above.
一、如图4所示,包括:First, as shown in Figure 4, including:
5G eNB与LTE eNB之间建立通信连接,若5G eNB与LTE eNB之间使用X5接口,那么本步骤可以是X5接口建立的流程。该通信连接可以是预先就建立好的通信连接;应用到图4所示的随机接入流程中,应当在步骤402之前完成建立。The communication connection is established between the 5G eNB and the LTE eNB. If the X5 interface is used between the 5G eNB and the LTE eNB, this step may be the process of establishing the X5 interface. The communication connection may be a communication connection established in advance; applied to the random access procedure shown in FIG. 4, the establishment should be completed before step 402.
401:UE向5G eNB发送LTE格式的RRC连接请求(Connection Request)消息,在RRC Connection Request消息中携带S-TMSI信息。401: The UE sends an RRC connection request (Connection Request) message in the LTE format to the 5G eNB, and carries the S-TMSI information in the RRC Connection Request message.
由于假设5G系统没有核心网,也没有RRC层,所以UE通过5G空口接入,也可以发送LTE格式的RRC Connection Request。至于UE怎么知道发送5G空口格式还是LTE格式的RRC Connection Request消息给5G eNB至少有3种可能性:第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)协议规定、5G空口广播指示或者LTE广播指示。Since the 5G system does not have a core network and no RRC layer, the UE can also send an RRC Connection Request in LTE format through the 5G air interface. As for how the UE knows whether to send the 5G air interface format or the LTE connection RRC Connection Request message to the 5G eNB, there are at least three possibilities: the 3rd Generation Partnership Project (3GPP) protocol, the 5G air interface broadcast indication, or the LTE broadcast. Instructions.
402:5G eNB将接收到的RRC Connection Request消息发送给LTE eNB。402: The 5G eNB sends the received RRC Connection Request message to the LTE eNB.
假设5G eNB事先和邻区LTE eNB建立好新接口,在本实施例中称为X5接口。例如5G eNB通过OAM配置获知邻区LTE eNB的传输层(Transport Network Layer,TNL)寻址地址,然后发起建立X5接口的请求。或者LTE eNB根据OAM配置获知邻区5G eNB的TNL寻址地址,然后发起建立X5接口的请求。在步骤403中,可以是5G eNB在X5接口上发送UE的RRC Connection Request消息。It is assumed that the 5G eNB establishes a new interface with the neighboring LTE eNB in advance, which is referred to as an X5 interface in this embodiment. For example, the 5G eNB learns the Transport Network Layer (TNL) addressing address of the neighboring LTE eNB through the OAM configuration, and then initiates a request to establish an X5 interface. Or the LTE eNB learns the TNL addressing address of the neighboring 5G eNB according to the OAM configuration, and then initiates a request to establish an X5 interface. In step 403, the 5G eNB may send an RRC Connection Request message of the UE on the X5 interface.
403:LTE eNB将RRC设置消息(Connection Request)里面携带的S-TMSI发送给5G eNB。403: The LTE eNB sends the S-TMSI carried in the RRC setup message (Connection Request) to the 5G eNB.
本实施例中,步骤404是在LTE eNB确定允许UE接入网络后执行的步骤;允许UE接入,可以是确定没有发生接入冲突的情况下,也可以是在发生了接入冲突选择其中的一个UE允许接入网络。In this embodiment, step 404 is performed after the LTE eNB determines that the UE is allowed to access the network; allowing the UE to access, may be determined that no access conflict occurs, or may be selected in an access conflict. One UE allows access to the network.
步骤404中发送的S-TMSI是RRC Connection Request里面包含的S-TMSI。
发送方式可以是采用新的消息发送,采用:LTE eNB从RRC Connection Request中拷贝的S-TMSI。还可以在发往上述UE的RRC连接设置(RRC Connection Setup)消息中携带S-TMSI。The S-TMSI transmitted in step 404 is the S-TMSI included in the RRC Connection Request.
The sending mode may be that a new message is sent, and the S-TMSI copied by the LTE eNB from the RRC Connection Request is adopted. The S-TMSI may also be carried in an RRC Connection Setup message sent to the UE.
404:5G eNB向UE回复msg4,在msg4中携带上述S-TMSI。404: The 5G eNB replies to the UE with the msg4 and carries the S-TMSI in the msg4.
S-TMSI可以包括在msg4的MAC协议数据单元(Protocol Data Unit,PDU)中。UE收到msg4后,根据MAC PDU中携带的S-TMSI判断RACH接入是否成功。若4G eNB发送的RRC Connection Setup消息中携带S-TMSI,那么Mg4可以是发送的来自LTE eNB的RRC Connection Setup消息。The S-TMSI may be included in a MAC Protocol Data Unit (PDU) of msg4. After receiving the msg4, the UE determines whether the RACH access is successful according to the S-TMSI carried in the MAC PDU. If the S-TMSI is carried in the RRC Connection Setup message sent by the 4G eNB, the M4 may be an RRC Connection Setup message sent from the LTE eNB.
二、如图5所示,包括:Second, as shown in Figure 5, including:
图5所示的X5接口建立可以参考前一实施例的说明。The X5 interface setup shown in FIG. 5 can be referred to the description of the previous embodiment.
501:UE向5G eNB发送LTE格式的RRC连接请求(Connection Request)消息,在5G空口协议层携带S-TMSI。501: The UE sends an RRC connection request (Connection Request) message in the LTE format to the 5G eNB, and carries the S-TMSI in the 5G air interface protocol layer.
由于5G eNB不具备RRC层,所以无法解读UE发送的RRC Connection Request消息,也就无法读取该消息中携带的S-TMSI,从而无法解决RACH冲突。因此假设UE在5G空口协议层,即PHY或PHY/MAC(对应CA模式)或PHY/MAC/RLC(对应DC模式)层增加S-TMSI,以便5G eNB解决RACH冲突。考虑到目前循环冗余校验码(Cyclic Redundancy Check)校验是在物理层做的,因此如果5G eNB可以解出MAC头(包含S-TMSI),那就意味着当5G eNB也能将其正确解调RRC connection Request消息获得S-TMSI。后续5G eNB就不需要将RRC Connection Request消息发送给LTE基站,从而减少在X5接口传递的消息数量。Since the 5G eNB does not have the RRC layer, the RRC Connection Request message sent by the UE cannot be interpreted, and the S-TMSI carried in the message cannot be read, so that the RACH collision cannot be resolved. It is therefore assumed that the UE adds S-TMSI at the 5G air interface protocol layer, ie PHY or PHY/MAC (corresponding CA mode) or PHY/MAC/RLC (corresponding DC mode) layer, so that the 5G eNB resolves the RACH collision. Considering that the current Cyclic Redundancy Check (Check) check is done at the physical layer, if the 5G eNB can solve the MAC header (including S-TMSI), it means that when the 5G eNB can also Correctly demodulate the RRC connection Request message to obtain the S-TMSI. The subsequent 5G eNB does not need to send an RRC Connection Request message to the LTE base station, thereby reducing the number of messages transmitted on the X5 interface.
502:5G eNB向UE回复msg4,S-TMSI携带在5G空口协议层。502: The 5G eNB replies to the UE with the msg4, and the S-TMSI is carried in the 5G air interface protocol layer.
具体可以是,在msg4的MAC PDU中携带S-TMSI,用于告知UE允许其接入。Specifically, the S-TMSI is carried in the MAC PDU of the msg4, and is used to notify the UE to allow access.
当UE收到携带S-TMSI的msg4之后,对比自身的S-TMSI,如果2者不同,则表示接入网络失败,该UE可以快速发起下一次接入网络的操作;如果相同,则UE确定接入网络成功。该方案的好处在于,不需要等待LTE基站通过读取RRC消息解决接入冲突,减少解决接入冲突所需的时间。After receiving the msg4 carrying the S-TMSI, the UE compares its own S-TMSI. If the two are different, it indicates that the access network fails, and the UE can quickly initiate the next access to the network; if the same, the UE determines The access network was successful. The advantage of this scheme is that there is no need to wait for the LTE base station to resolve the access conflict by reading the RRC message, and reduce the time required to resolve the access conflict.
进一步地,还可以继续执行后续步骤,需要说明的是后续步骤在本实施例
中不属于网络接入解决接入冲突的步骤。Further, the subsequent steps may be further performed, and it is necessary to explain that the subsequent steps are in this embodiment.
It does not belong to the steps of network access to resolve access conflicts.
503:5G eNB通过X5接口上将RRC连接请求(Connection Request)消息发送给LTE基站。LTEeNB通过5G eNB将RRC连接设置(Connection Setup)消息发给UE。503: The 5G eNB sends an RRC connection request (Connection Request) message to the LTE base station through the X5 interface. The LTE eNB sends an RRC Connection Setup message to the UE through the 5G eNB.
执行本步骤是由于LTE eNB后续可能需要根据RRC connection Request中的S-TMSI为UE选择MME,以便后续UE和核心网建立连接。This step is performed because the LTE eNB may need to select the MME for the UE according to the S-TMSI in the RRC connection Request, so that the subsequent UE establishes a connection with the core network.
504:UE通过5G eNB将RRC连接设置完成(Connection Setup complete)消息发送给LTE基站。后续5G eNB就不需要将多余UE的RRC Connection Request消息发送给LTE基站,可以减少不必要的X5接口消息。504: The UE sends an RRC Connection Setup Complete message to the LTE base station by using the 5G eNB. The subsequent 5G eNB does not need to send the RRC Connection Request message of the redundant UE to the LTE base station, which can reduce unnecessary X5 interface messages.
三、如图6所示,具体如下:Third, as shown in Figure 6, the details are as follows:
图6所示的X5接口建立可以参考图4所示实施例的说明。The X5 interface setup shown in FIG. 6 can be referred to the description of the embodiment shown in FIG.
601:UE向5G eNB发送LTE格式的RRC连接请求(Connection Request消息),在RRC Connection Request消息中携带S-TMSI信息。601: The UE sends an RRC connection request (Connection Request message) in the LTE format to the 5G eNB, and carries the S-TMSI information in the RRC Connection Request message.
602:5G eNB将RRC Connection Request消息发送给LTE eNB。602: The 5G eNB sends an RRC Connection Request message to the LTE eNB.
603:LTE eNB通过5G eNB发送包含S-TMSI的RRC连接设置(Connection Setup)给UE。603: The LTE eNB sends an RRC connection setup (Connection Setup) including the S-TMSI to the UE through the 5G eNB.
UE收到RRC Connection Setup消息后,通过读取该消息中包含的S-TMSI判断接入网络是否成功。之后UE可以通过RRC层通知5G空口MAC层接入网络成功,则5G空口MAC层不需要再继续尝试随机接入。After receiving the RRC Connection Setup message, the UE determines whether the access network is successful by reading the S-TMSI included in the message. After the UE can notify the 5G air interface MAC layer to access the network through the RRC layer, the 5G air interface MAC layer does not need to continue to try random access.
