Description

一种近距离业务通信方法、相关设备及***Short-distance service communication method, related equipment and system 技术领域Technical field
本发明涉及通信技术领域，尤其涉及一种近距离业务通信方法、相关设备及***。The present invention relates to the field of communications technologies, and in particular, to a short-range service communication method, related device and system.
背景技术Background technique
目前，第三代合作伙伴项目(英文全称：3rd Generation Partnership Project，缩写：3GPP)为实现近距离通信功能，在近距离用户设备(User Equipment，简称UE)之间提供近距离业务(英文全称：Proximity Service，缩写：ProSe)，即在网络侧引入ProSe功能(ProSe Function)网元，用来专门处理ProSe所需的相关动作与流程，通过建立分组数据网络(英文全称：Packet Data Network，缩写：PDN)连接来传递UE与ProSe功能网元之间的控制信令，该PDN连接的建立，需要选择该PDN的接入点名称(英文全称：Access Point Name，简称APN)，从而该APN的选择决定了使用哪个PDN来连接ProSe功能网元。At present, the third-generation partner project (English name: 3rd Generation Partnership Project, abbreviation: 3GPP) provides close-range services between close-range user equipment (User Equipment, UE for short) to achieve short-range communication functions (English full name: Proximity Service, abbreviated as ProSe), which introduces a ProSe Function network element on the network side to specifically handle the related actions and processes required by ProSe, and establishes a packet data network (English name: Packet Data Network, abbreviation: PDN) is connected to transmit control signaling between the UE and the ProSe function network element. For the establishment of the PDN connection, the access point name of the PDN (English name: Access Point Name, APN for short) is selected, so that the selection of the APN is performed. It is decided which PDN to use to connect to the ProSe function network element.
不同的运营商针对不同的场景可以配置不同的APN来建立PDN连接，考虑到非漫游场景与漫游场景下对ProSe特性的支持，UE需要直接与两种类型的ProSe功能网元进行通信，即：在非漫游场景下与归属ProSe功能网元进行通信，在漫游场景下与拜访ProSe功能网元进行通信。为了减少跨网络通信，3GPP限定了在上述两种场景下，UE均只能与其归属ProSe功能网元进行直接通信，UE与拜访ProSe功能网元之间的通信，需要通过归属ProSe功能网元完成。Different operators can configure different APNs to establish PDN connections for different scenarios. Considering the support of ProSe features in non-roaming scenarios and roaming scenarios, the UE needs to directly communicate with two types of ProSe functional network elements, namely: The non-roaming scenario communicates with the home ProSe function network element, and communicates with the visited ProSe function network element in the roaming scenario. In order to reduce cross-network communication, the 3GPP defines that in the above two scenarios, the UE can only communicate directly with the home ProSe function network element. The communication between the UE and the visited ProSe function network element needs to be completed by the home ProSe function network element. .
为了使用具备访问归属ProSe功能网元的能力的APN来建立PDN连接以实现UE与归属ProSe功能网元之间的直接通信，现有技术中，归属运营商在UE侧预先配置了APN，从而可以在非漫游场景下使用该APN来建立PDN连接，保证通过该PDN连接能够路由到归属ProSe功能网元。但是对于漫游场景，如果仍然使用归属运营商在UE侧配置的APN来建立PDN连接，则不能保证能够通过该PDN连接路由到归属ProSe功能网元，更坏情况下，拜访ProSe功能网元可能因为不支持归属运营商配置的APN而拒绝PDN连接建立请求。 In order to establish a PDN connection to implement direct communication between the UE and the home ProSe function network element, the home operator pre-configures the APN on the UE side, so that the home network can be configured in advance. The APN is used in a non-roaming scenario to establish a PDN connection, and the PDN connection can be routed to the home ProSe functional network element. However, for a roaming scenario, if the APN configured by the home operator on the UE side is still used to establish a PDN connection, the PDN connection cannot be guaranteed to be routed to the home ProSe function network element. In the worse case, the access to the ProSe function network element may be because The APN configured by the home operator is not supported and the PDN connection establishment request is rejected.

The M2M user equipment can be called a Machine Type Communication Device (MTC Device).
本发明实施例提及的归属网络与拜访网络，非漫游状态与漫游状态，是相对于UE来说的。UE的归属网络是UE的国际移动用户标识(英文全称：International Mobile Subscriber Identity，缩写：IMSI)中包含的公共陆地移动网络(英文全称：Public Land Mobile Network，缩写：PLMN)身份标识(英文全称：Identity，缩写：ID)所标识的网络，若UE处于其归属网络中，则该UE处于非漫游状态，若UE不处于其归属网络中，则该UE处于漫游状态。UE的拜访网络是当UE处于漫游状态时访问的网络。The home network and the visited network, the non-roaming state and the roaming state mentioned in the embodiments of the present invention are relative to the UE. The home network of the UE is the public land mobile network (English name: Public Land Mobile Network, abbreviation: PLMN) identity contained in the International Mobile Subscriber Identity (English name: IMSI) of the UE (English full name: English full name: Identity, abbreviation: ID) identifies the network. If the UE is in its home network, the UE is in a non-roaming state. If the UE is not in its home network, the UE is in a roaming state. The visited network of the UE is a network that is accessed when the UE is in a roaming state.
本发明实施例中提及两种场景：非漫游场景与漫游场景。请参阅图1a，在非漫游场景下，进行ProSe通信的UE驻留在同一个归属网络中，处于归属网络中的ProSe功能网元称为归属ProSe功能网元，所有UE(例如:图1a中的UE A和UE B)可以通过PC3接口与其归属ProSe功能网元之间进行直接通信。需要说明的是，PC3接口是UE与归属ProSe功能网元之间的对等接口，PC3接口上的通信是通过演进分组***(英文全称：Evolved Packet System，缩写：EPS)用户面实现的，在图1a中省略了EPS中的演进型节点B(英文全称：Evolved Node B，缩写：eNodeB),服务网关(英文全称：Serving Gateway，缩写：Serving GW)，分组数据网络网关(英文全称：Packet Data Network Gateway，缩写：PDN GW)以及网关与底层的所有接口协议。Two scenarios are mentioned in the embodiment of the present invention: a non-roaming scenario and a roaming scenario. Referring to FIG. 1a, in a non-roaming scenario, a UE performing ProSe communication resides in the same home network, and a ProSe function network element in the home network is called a home ProSe function network element, and all UEs (for example, FIG. 1a) UE A and UE B) can directly communicate with their home ProSe functional network elements through the PC3 interface. It should be noted that the PC3 interface is a peer interface between the UE and the home ProSe function network element, and the communication on the PC3 interface is implemented by the user plane of the Evolved Packet System (abbreviation: EPS). The evolved Node B in the EPS (English full name: Evolved Node B, abbreviation: eNodeB), the service gateway (English full name: Serving Gateway, abbreviation: Serving GW), and the packet data network gateway (English full name: Packet Data) is omitted in Figure 1a. Network Gateway, abbreviation: PDN GW) and all interface protocols between the gateway and the underlying.
请参阅图1b，在漫游场景下，进行ProSe通信的UE驻留在漫游地的拜访网 络中，处于拜访网络中的ProSe功能网元称为拜访ProSe功能网元，比如图1b中，UE A的归属网络是PLMN A，UE A漫游到PLMN C中，UE A需要与PLMN C中拜访ProSe功能网元进行通信以获得进行ProSe通信的授权，但该通信是通过UE的归属ProSe功能网元实现的，比如图1b中，UE A先与PLMN A中的ProSe功能网元(即UE A的归属ProSe功能网元)进行直接通信，再通过PLMN A中ProSe功能网元实现UE A与PLMN C中ProSe功能网元的通信。归属ProSe功能网元与拜访ProSe功能网元之间的通信接口为PC7。Referring to FIG. 1b, in a roaming scenario, a UE performing ProSe communication resides in a visited network of a roaming place. In the network, the ProSe function network element in the visited network is called a visited ProSe function network element. For example, in FIG. 1b, the home network of UE A is PLMN A, UE A roams into PLMN C, and UE A needs to visit with PLMN C. The ProSe function network element communicates to obtain the authorization for the ProSe communication, but the communication is implemented by the UE's home ProSe function network element. For example, in FIG. 1b, the UE A first and the ProSe function network element in the PLMN A (ie, UE A) The locating ProSe function network element performs direct communication, and then the communication between the UE A and the ProSe functional network element in the PLMN C is implemented by the ProSe functional network element in the PLMN A. The communication interface between the home ProSe function network element and the visited ProSe function network element is PC7.
本发明实施例中提及的具备访问UE的归属ProSe功能网元能力的APN，是指移动管理网元根据该APN可以选择对应的一个PDN网关建立PDN连接，通过该PDN连接实现UE与归属ProSe功能网元之间的通信，若根据APN可以选择一个PDN网关建立PDN连接实现与该UE的归属Prose功能网元之间的通信，则该APN具备访问该UE的归属Prose功能网元的能力，也可以理解为该APN为访问UE的归属Prose功能网元所需的APN，为描述方便，本发明实施例中，将具备访问UE的归属Prose功能网元能力的APN，也即访问UE的归属Prose功能网元所需的APN，称为ProSe APN。The APN with the capability of accessing the home ProSe function network element of the UE mentioned in the embodiment of the present invention means that the mobility management network element can establish a PDN connection according to the PDN gateway that can be selected by the APN, and implement the UE and the home ProSe through the PDN connection. The APN has the capability of accessing the home Prose function network element of the UE, if the APN can select a PDN gateway to establish a PDN connection to implement communication with the home Prose function network element of the UE. It can also be understood that the APN is an APN required to access the home Prose function network element of the UE. For the convenience of description, in the embodiment of the present invention, the APN that accesses the home Prose function network element capability of the UE, that is, the access to the UE The APN required by the Prose function network element is called ProSe APN.
在现有技术中，为了使用具备访问归属ProSe功能网元能力的APN来建立PDN连接以实现UE与归属ProSe功能网元之间的直接通信，归属运营商在UE侧预先配置了APN，通过该APN建立PDN连接，但是，在实际应用中，只有在非漫游场景下，能够保证通过该PDN连接路由到归属ProSe功能网元，而在漫游场景下，如果仍然使用归属运营商在UE侧配置的APN来建立PDN连接，则不能保证能够通过该PDN连接路由到归属ProSe功能网元(比如归属运营商根据本地策略或者漫游协议可能限制该PDN连接路由到归属ProSe功能网元)，更坏情况下，拜访ProSe功能网元可能因为不支持归属运营商配置的APN而拒绝PDN连接建立请求，因此，展开以下论述：In the prior art, in order to establish a PDN connection by using an APN having the capability of accessing the home ProSe function network element to implement direct communication between the UE and the home ProSe function network element, the home operator pre-configures the APN on the UE side. The APN establishes a PDN connection. However, in a non-roaming scenario, the APN can ensure that the PDN is routed to the home ProSe function network element. In the roaming scenario, if the home carrier is still configured on the UE side. If the APN is used to establish a PDN connection, the PDN connection cannot be guaranteed to be routed to the home ProSe function network element. For example, the home operator may restrict the PDN connection route to the home ProSe function network element according to the local policy or the roaming agreement. The visit to the ProSe function network element may refuse the PDN connection establishment request because the APN configured by the home carrier is not supported. Therefore, the following discussion is initiated:
下面从移动管理网元的角度，对本发明方案进行介绍。The present invention will be described below from the perspective of a mobile management network element.
本发明近距离业务通信方法的一个实施例，可包括：移动管理网元确定用户设备UE访问UE的归属近距离业务ProSe功能网元所需的接入点名称APN；移动管理网元将确定的APN发送给UE，以使UE使用该APN建立分组数据网络PDN连接。 An embodiment of the short-range service communication method of the present invention may include: the mobility management network element determines an access point name APN required for the user equipment UE to access the ProSe function network element of the UE's home proximity service; the mobility management network element shall determine The APN is sent to the UE to enable the UE to establish a packet data network PDN connection using the APN.
请参阅图2，具体可包括：Please refer to FIG. 2, which may specifically include:
201、移动管理网元确定用户设备UE访问UE的归属近距离业务ProSe功能网元所需的接入点名称APN；201. The mobility management network element determines an access point name APN required by the user equipment UE to access the ProSe function network element of the UE's home proximity service;
与现有技术不同的是，在本发明实施例中，为支持ProSe的UE，运营商协商确定访问UE的归属Prose功能网元所需的APN，并将该确定的APN配置在网络侧，例如，配置在签约用户服务器(英文全称：Home Subscriber Server，缩写：HSS)或者移动管理网元中。移动管理网元可以直接将网络侧配置的APN确定为访问UE的归属Prose功能网元所需的APN，该APN具备访问该UE的归属Prose功能网元的能力，即ProSe APN，需要说明的是，移动管理网元可以为UE确定一个ProSe APN，也可以确定至少两个ProSe APN。或者移动管理网元接收UE发送的UE中配置的APN，当确定UE中配置的APN具备访问归属Prose功能网元的能力时，进一步将UE中配置的APN确定为访问UE的归属Prose功能网元所需的APN，即ProSe APN，从而确保在任何场景下，UE使用具备访问归属Prose功能网元的APN建立PDN连接，通过该PDN连接实现UE与归属ProSe功能网元之间的通信。Different from the prior art, in the embodiment of the present invention, for the UE supporting the ProSe, the operator negotiates the APN required to access the home Prose function network element of the UE, and configures the determined APN on the network side, for example, , configured in the subscription user server (English full name: Home Subscriber Server, abbreviation: HSS) or mobile management network element. The mobility management network element can directly determine the APN configured on the network side as the APN required to access the home Prose function network element of the UE, and the APN has the capability of accessing the home Prose function network element of the UE, that is, the ProSe APN. The mobility management network element may determine a ProSe APN for the UE, and may also determine at least two ProSe APNs. Or the mobile management network element receives the APN configured in the UE that is sent by the UE, and determines that the APN configured in the UE has the capability to access the home Prose function network element, and further determines the APN configured in the UE as the home Prose function network element that accesses the UE. The required APN, that is, the ProSe APN, ensures that in any scenario, the UE establishes a PDN connection using the APN having access to the home Prose function network element, and the communication between the UE and the home ProSe functional network element is implemented through the PDN connection.
不同的运营商针对不同的场景与处于不同状态的UE，可以配置不同的APN：当UE处于非漫游状态时，归属运营商可以根据本地策略(locally configured operator's policies)在HSS或移动管理网元上配置ProSe APN，比如将缺省APN配置为ProSe APN；当UE处于漫游状态时，归属运营商可以根据本地策略或者漫游协议在HSS中配置其归属UE在各漫游场景下使用的ProSe APN，拜访运营商可以根据本地策略或者漫游协议(roaming agreement)在移动管理网元上配置处于漫游状态的UE所使用的ProSe APN，比如配置使用一个专用的ProSe APN。Different operators can configure different APNs for different scenarios and UEs in different states: When the UE is in a non-roaming state, the home carrier can be on the HSS or the mobility management network element according to the locally configured operator's policies. The ProSe APN is configured, for example, the default APN is configured as a ProSe APN. When the UE is in the roaming state, the home operator can configure the ProSe APN used by the home UE in each roaming scenario according to the local policy or the roaming protocol, and visit the operation. The Provider can configure the ProSe APN used by the roaming UE on the mobility management network element according to a local policy or a roaming agreement, such as configuring a dedicated ProSe APN.
可以理解的是，当UE位于其归属网络时，可认为UE处于非漫游状态，当UE不在其归属网络时，可认为UE处于漫游状态。It can be understood that when the UE is located in its home network, the UE can be considered to be in a non-roaming state, and when the UE is not in its home network, the UE can be considered to be in a roaming state.
202、移动管理网元将确定的APN发送给UE，以使UE使用该APN建立分组数据网络PDN连接。202. The mobility management network element sends the determined APN to the UE, so that the UE establishes a packet data network PDN connection by using the APN.
由于在步骤201中，移动管理网元预先确定ProSe APN，则将确定ProSe APN发送给UE，后续UE使用该确定的ProSe APN发起PDN连接建立请求，即 在该PDN连接建立请求中携带所确定的ProSe APN，在PDN连接建立请求触发的PDN连接建立流程中，移动管理网元通过该ProSe APN可以选择一个PDN网关，并向UE发送缺省(default)承载激活请求，UE接受该缺省承载激活请求并向移动管理网元发送缺省承载激活接受消息，从而成功建立PDN连接，通过该PDN连接实现所述UE与归属ProSe功能网元之间的通信。Since in step 201, the mobility management network element predetermines the ProSe APN, it will determine that the ProSe APN is sent to the UE, and the subsequent UE initiates the PDN connection establishment request using the determined ProSe APN, ie The PDN connection establishment request carries the determined ProSe APN. In the PDN connection establishment procedure triggered by the PDN connection establishment request, the mobility management network element can select a PDN gateway through the ProSe APN, and send a default (default) to the UE. Carrying the activation request, the UE accepts the default bearer activation request and sends a default bearer activation accept message to the mobility management network element, so as to successfully establish a PDN connection, and implement communication between the UE and the home ProSe functional network element through the PDN connection. .
需要说明的是，移动管理网元发送给UE的ProSe APN可以为一个，或者至少两个，当ProSe APN为至少两个时，移动管理网元可以以列表的形式发送给UE，比如ProSe APN列表(ProSe APN list)，此处不做具体限定。可以理解的是，网络侧可以通过新的信元下发所确定的APN，比如信元“ProSe APN”或者“ProSe capable APN”或者“ProSe APN list”。It should be noted that the ProSe APN sent by the mobility management network element to the UE may be one, or at least two. When the ProSe APN is at least two, the mobility management network element may be sent to the UE in the form of a list, such as a ProSe APN list. (ProSe APN list), which is not specifically limited herein. It can be understood that the network side can deliver the determined APN through a new cell, such as the cell “ProSe APN” or “ProSe capable APN” or “ProSe APN list”.
本发明实施例中，由于运营商预先协商确定ProSe APN，并将该确定的ProSe APN配置在网络侧，例如：配置在HSS或者移动管理网元中，而后续移动管理网元可以直接从网络侧获取ProSe APN，该ProSe APN具备访问归属Prose功能网元的能力；移动管理网元通过该ProSe APN可以选择对应的一个PDN网关建立PDN连接，通过该PDN连接实现UE与归属ProSe功能网元之间的通信。或者移动管理网元接收UE发送的UE中配置的APN，确定UE中配置的APN具备访问归属Prose功能网元的能力时，进一步确定UE中配置的APN确定为访问UE的Prose功能网元所需的APN，从而确保UE在任何场景下，使用具备访问UE的归属Prose功能网元的APN建立PDN连接，通过该PDN连接实现所述UE与归属ProSe功能网元之间的通信。In the embodiment of the present invention, the ProSe APN is determined by the operator in advance, and the determined ProSe APN is configured on the network side, for example, in the HSS or the mobility management network element, and the subsequent mobility management network element can be directly from the network side. Obtaining a ProSe APN, the ProSe APN having the capability of accessing the home Prose function network element; the mobility management network element can select a corresponding PDN gateway to establish a PDN connection through the ProSe APN, and the PDN connection is used to implement the UE and the home ProSe function network element. Communication. Or the mobile management network element receives the APN configured in the UE that is sent by the UE, and determines that the APN configured in the UE has the capability of accessing the Prorose function network element, and further determines that the APN configured in the UE is determined to be the Prose function network element for accessing the UE. The APN is used to ensure that the UE establishes a PDN connection using the APN having the home Prose function network element that accesses the UE in any scenario, and the communication between the UE and the home ProSe functional network element is implemented through the PDN connection.

例如：当UE处于非漫游状态时，移动管理网元可以直接使用HSS发送的APN确定为所需APN，若HSS没有向移动管理网元发送APN，则移动管理网元可以使用移动管理网元中配置的APN确定为所需APN。当UE处于漫游状态时，若HSS没有向移动管理网元发送APN，则移动管理网元可以使用移动管理网元中配置的APN确定为所需APN；或者若HSS向移动管理网元发送了APN信息且移动管理网元中没有配置APN，则移动管理网元可以使用HSS发送的APN确定为所需APN；或者若HSS向移动管理网元发送了APN，且移动管理网元中也配 置了APN，则移动管理网元需要根据本地策略与漫游协议来确定使用哪个APN为所需APN，优先使用HSS发送的APN，或者优先使用移动管理网元发送的APN，此处不做具体限定。For example, when the UE is in a non-roaming state, the mobility management network element can directly determine the required APN by using the APN sent by the HSS. If the HSS does not send the APN to the mobility management network element, the mobility management network element can use the mobility management network element. The configured APN is determined to be the required APN. When the UE is in the roaming state, if the HSS does not send the APN to the mobility management network element, the mobility management network element may determine the required APN using the APN configured in the mobility management network element; or if the HSS sends the APN to the mobility management network element. If the APN is not configured in the mobility management network element, the mobility management network element may use the APN sent by the HSS to determine the required APN; or if the HSS sends the APN to the mobility management network element, and the mobile management network element also If the APN is set, the mobility management network element needs to determine which APN to use as the required APN according to the local policy and the roaming protocol, and preferentially use the APN sent by the HSS, or preferentially use the APN sent by the mobility management network element, which is not specifically limited herein. .
可以理解的是，由于HSS与移动管理网元比较，更容易更新配置，进而保存运营商协商确定的相关签约数据，因此可优先使用HSS中发送的APN。It can be understood that, because the HSS is more easily updated with the mobile management network element, and the related subscription data determined by the operator negotiation is saved, the APN sent in the HSS can be preferentially used.
