The present disclosure is a National Stage of International Patent Application No. PCT/CN2017/087617, filed on Jun. 8, 2017, and claims benefit of Chinese Patent Application No. 201610405263.X, filed on Jun. 8, 2016, the contents of which are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

The present disclosure relates to the technical field of communications, and in particular to a method and apparatus for transmitting data and a storage medium.

BACKGROUND

Currently, when User Equipment (UE) does not need to transmit any service data, it is in an idle state. The Idle state facilitates the power saving of the UE, and also avoids frequent initiation of a handover process to a network side when the UE moves, thereby increasing the signaling processing load at the network side.

When a third-party server needs to send a downlink data packet to the UE, a data connection is established based on the following process.

As illustrated inFIG. 1, the third-party server sends a downlink data packet sent to the UE in the Idle state to a Public Data Network (PDN) Gate Way (PGW), the PGW sends the downlink data packet to a Serving Gate Way (SGW), and the SGW caches the downlink data packet. The SGW sends a downlink data notification message to a Mobility Management Entity (MME). At this time, if the SGW receives another downlink data packet of the UE, the SGW caches these data packets, but does not send a new downlink data notification message. The MME sends a paging message to a base station (eNodeB) of a tracking area registered by each UE. The eNodeB pages the UE. The UE triggers a service request process, and establishes a connection with the network side. So far, an S1-U downlink data channel between the SGW and the base station is established.

In the above process, the SGW, the MME and the base station are required to negotiate to establish a data channel. If downlink data arrives frequently at intervals, the data channel needs to be negotiated frequently. In addition, the SGW needs to have the capability of caching downlink data until the data channel between the SGW and the base station is established. It is apparent that this mode increases the signaling load and data processing burden at the network side.

In order to alleviate the signaling load and data processing burden at the network side, for terminals based on weak mobile requirements, especially for some terminals without mobility requirements (such as electronic report users), a 3rd Generation Partnership Project (3GPP) proposed a Narrow Band Internet of Things (NB-IOT) solution. This solution proposes two transmission schemes. As illustrated inFIG. 2, one transmission scheme is a control plane scheme (also called a control plane optimization scheme): under this scheme, there is no need to establish an S1-U bearer, and a downlink small data packet is transmitted to an MME through a Non-Access Stratum (NAS) signaling in a channel associated manner and then sent to a UE, that is, a transmission path of the downlink data packet is third-party server→PGW→SGW→MME→base station→UE. Correspondingly, the transmission path of an uplink data packet under the control plane scheme is UE→base station→MME→SGW→PGW→third-party server. The other transmission scheme is a user plane scheme. This transmission scheme needs to establish an S1-U bearer. A transmission path of a downlink data packet is third-party server→PGW→SGW→base station→UE, and a transmission path of an uplink data packet is UE→base station→SGW→PGW→third-party server. The SGW/PGW belongs to a user plane network element, the MME belongs to a control plane network element, and the base station belongs to an access network element. In the above solution, the control plane scheme is suitable for the case where a small data packet is transmitted, and the user plane scheme is suitable for the scenario where the data packet is large and the transmission time interval is long.

Currently, for a specific private network, the NB-IOT solution will select one of the above two transmission schemes. Because different UEs may have different service transmission requirements under the private network, even if the service transmission requirements of the same UE at different times are also different, the mode of selecting a specific transmission scheme for a specific private network in the related art cannot satisfy constantly diversified service scenario requirements.

The UE type is a digital electric meter, a digital water meter, or the like. The third-party device type is a video content server, a data acquisition system, or the like. Based on the location information of a UE and/or a third-party server, a user plane network element closest to the location of the UE and/or the third-party server may be selected for the UE.

At S302, the first device determines data transmission path information corresponding to the service related information of the UE.

Here, the data transmission path information may include at least one of service transmission scheme information or information related to a first user plane network element.

The determined service transmission scheme is a user plane scheme or a control plane scheme, the user plane scheme is a scheme for transmitting service data through a user plane and an access network, and the control plane scheme is a scheme for transmitting service data through a user plane, a control plane and an access network.

In a specific implementation, the first device may first acquire subscription information or policy information of a UE from the database, determine, based on the subscription information or the policy information of the UE, whether to establish a data connection for the UE (for example, if the UE does not enable a data connection function, a data connection does not need to be established for the UE), or determine whether to establish a data connection for the UE according to an instruction in an initial attach request initiated by the UE.

After it is determined to establish the data connection for the UE, the foregoing operations of acquiring service related information of the UE and determining data transmission path information corresponding to the service related information are performed, otherwise, a data connection is not established for the UE.

In the embodiment of the present disclosure, the establishment of a data transmission path of a UE may be initiated by an instruction network element (preferably, a third-party server), or may be initiated by the UE. There may be the following modes specifically.

Mode 1: An instruction network element initiates the establishment of a data transmission path for a UE.

As an implementation, the first device is a control plane network element or a second control plane functional entity. At this time, the operation that the first device acquires service related information of a UE includes: the first device receives data connection establishment instruction information sent by an instruction network element, and acquires service related information of the UE according to the data connection establishment instruction information, the data connection establishment instruction information being used to instruct the first device to determine, for the UE, data transmission path information corresponding to the service related information of the UE.

Correspondingly, the instruction network element determines data connection establishment instruction information, the data connection establishment instruction information being used to instruct a first device to determine, for a User Equipment (UE), data transmission path information corresponding to service related information of the UE; and the data connection establishment instruction information is sent to the first device.

In the above implementation, the data connection establishment instruction information may include the service related information of the UE; or, the data connection establishment instruction information may not include the service related information of the UE. At this time, the operation that the first device acquires service related information of the UE according to the data connection establishment instruction information from the instruction network element includes the following operation.

The first device queries the service related information of the UE locally or from a database, a policy server, a DNS server, a third-party server, a capability open platform or an independent network element at a network side, according to the UE identification information in the data connection establishment instruction information.

In the above implementation, the instruction network element is any one of the following:

a third-party server; a capability open platform; a DNS; a database; an independent network element having a path selection function at a network side.

Description of a triggering mode for data connection establishment:

Trigger mode 1: For example, the instruction network element is a third-party server, and the third-party server may trigger the establishment of a data connection for the UE through a control plane:

Case 1: The first device is the control plane network element.

Specifically, the operation of receiving, by the control plane network element, data connection establishment instruction information initiated by a third-party server may include: the control plane network element receives the data connection establishment instruction information sent by the third-party server through the capability open platform. That is, the third-party server sends the data connection establishment instruction information to the control plane network element through the capability open platform. At this time, a transmission path of data connection establishment instruction information is a third-party server→capability open platform→control plane network element.

Case 2: The first device is a second control plane functional entity.

Specifically, the operation that the second control plane functional entity receives the data connection establishment instruction information initiated by an instruction network element may include that:

the second control plane functional entity receives, from the first control plane functional entity, the data connection establishment instruction information sent by the instruction network element, the data connection establishment instruction information from the instruction network element carrying or not carrying the service related information of the UE; or,

the second control plane functional entity receives data connection establishment instruction information sent by the first control plane functional entity and service related information of the UE queried by the first control plane functional entity, the data connection establishment instruction information being sent by the instruction network element and not carrying the service related information of the UE.

In a specific implementation, the first control plane functional entity may send the data connection establishment instruction information to a second control plane functional entity after receiving the data connection establishment instruction information initiated by the instruction network element, so that the second control plane functional entity determines, for the UE, data transmission path information corresponding to service related information of the UE. Or, the first control plane functional entity may query service related information of the UE based on UE identification information in the data connection establishment instruction information after receiving the data connection establishment instruction information initiated by the instruction network element, and send the data connection establishment instruction information and the service related information of the UE to a second control plane functional entity.

In the above process, when the instruction network element is a third-party server, the operation that the first control plane functional entity receives data connection establishment instruction information initiated by an instruction network element includes: the first control plane functional entity receives the data connection establishment instruction information sent by the third-party server through the capability open platform.

That is, when the first device is the second control plane functional entity, when the third-party server triggers the establishment of the data connection for the UE through a control plane, the transmission path of the data connection establishment instruction information is a third-party server→capability open platform→first control plane functional entity→second control plane functional entity.

Trigger mode 2: For example, the instruction network element is a third-party server, and the third-party server may trigger the establishment of a data connection for the UE through a user plane:

Case 1: The first device is the control plane network element.

Specifically, the operation that a first device receives data connection establishment instruction information initiated by an instruction network element includes:

the control plane network element receives, form the second user plane network element, data connection establishment instruction information sent by the instruction network element; here, the instruction network element sends the data connection establishment instruction information to the second user plane network element through a user plane link or a control plane link, and the data connection establishment instruction information from the instruction network element carries or does not carry the service related information of the UE; or,

the control plane network element receives data connection establishment instruction information sent by the second user plane network element and the service related information of the UE queried by the second user plane network element. Here, the data connection establishment instruction information is sent by the instruction network element to the second user plane network element. Here, the instruction network element sends the data connection establishment instruction information to the second user plane network element through a user plane link or a control plane link, and the data connection establishment instruction information from the instruction network element does not carry the service related information of the UE.

That is, if the first device is the control plane network element, when the third-party server triggers the establishment of the data connection for the UE through a user plane, the transmission path of the data connection establishment instruction information is a third-party server→capability open platform→second user plane network element→control plane network element. The second user plane network element here may be the same as or different from the first user plane network element in the final determined data transmission path.

Case 2: The first device is a second control plane functional entity.

Specifically, the first control plane functional entity receives, from a second user plane network element, data connection establishment instruction information sent by the instruction network element. Then, the first control plane functional entity may send the data connection establishment instruction information to the second control plane functional entity, so that the second control plane functional entity determines, for a UE, data transmission path information corresponding to service related information of the UE. Or, when the data connection establishment instruction information of the instruction network element does not carry the service related information of the UE, the first control plane functional entity may query service related information of the UE based on UE identification information in the data connection establishment instruction information, and send the data connection establishment instruction information and the service related information of the UE to a second control plane functional entity.

In the above cases, when the third-party server triggers the establishment of the data connection for the UE through a user plane, the transmission path of the data connection establishment instruction information is a third-party server→capability open platform→second user plane network element→first control plane functional entity→second control plane functional entity.

In summary, in the embodiment of the present disclosure, the control plane network element or the first control plane functional entity may directly receive the data connection establishment instruction information (control plane trigger) sent by the third-party server through the capability open platform, or may receive, form the second user plane network element, the data connection establishment instruction information (user plane trigger) sent by the third-party server.

Mode 2: A UE initiates establishment of a data transmission path.

Specifically, the operation that a first device acquires service related information of a UE includes: a first device receives an access request initiated by a UE, and acquires service related information of the UE based on the access request. The access request is an initial attach request or a service request.

Here, the access request may carry the service related information of the UE; or, the access request does not carry the service related information of the UE.

When the access request does not carry the service related information of the UE, the operation that the service related information of the UE is acquired based on the access request includes: the first device queries the service related information of the UE locally or from a database, a policy server, a DNS server, a third-party server, a capability open platform or an independent network element of a network side according to UE identification information in the access request.

In the above implementation, if the first device is the second control plane functional entity, the operation that the second control plane functional entity receives the access request includes: the second control plane functional entity receives the access request sent by the first control plane functional entity, the access request carrying or not carrying the service related information of the UE. Here, a first control plane functional entity receives an access request initiated by a UE, and sends it to a second control plane functional entity.

Or, the second control plane functional entity receives the access request sent by the first control plane functional entity and service related information of the UE queried by the first control plane functional entity, the access request not carrying the service related information of the UE. Here, a first control plane functional entity queries service related information of a UE based on UE identification information in a received access request, and sends the access request and the service related information of the UE to a second control plane functional entity.

The following contents are applicable to the above modes 1 and 2.

In a specific implementation, if the first device is the control plane network element or the second control plane functional entity, the operation that the first device determines data transmission path information corresponding to the service related information of the UE includes: data transmission path information corresponding to the service related information of the UE is queried locally or from a database, a policy server, a DNS server, a third-party server, a capability open platform or an independent network element having a path selection function at a network side.

As an implementation A, the determined service transmission scheme is a user plane scheme:

Correspondingly, when data disconnection instruction information sent by an instruction network element is received, the first user plane network element and the access network element the UE has accessed are instructed to release the service data transmission resources allocated for the UE according to the data disconnection instruction information.

As another implementation B, the determined service transmission scheme is a control plane scheme:

Correspondingly, after data disconnection instruction information sent by an instruction network element is received, the first user plane network element the UE has accessed is instructed to release the service data transmission resources allocated for the UE according to the data disconnection instruction information.

In the above implementations A and B, the resource allocation instruction information further includes service flow description information, used to instruct to store a mapping relationship between the service flow description information and the allocated service data transmission resources, to determine, upon reception of service data to be sent, a service data transmission resource corresponding to the service data to be sent according to service flow description information carried in the service data to be sent.

In the above implementations A and B, the resource allocation instruction information further includes a Quality of Service (QoS) policy, the QoS policy is used to instruct to allocate a service data transmission resource satisfying the QoS policy.

Specifically, the first device acquires the QoS policy according to the following operations:

the first device queries a QoS policy corresponding to the service related information locally or form a database, a policy server, a DNS server, a third-party server, a capability open platform or an independent network element having a path selection function at a network side based on the acquired service related information.

In the first embodiment, if the first device is a third-party server, a capability open platform, a DNS, a database, or an independent network element at a network side instead of a control plane network element or a second control plane functional entity, after the first device determines data transmission path information corresponding to the service related information of the UE, the method further includes: the determined data transmission path information is sent to the control plane network element or the second control plane functional entity the UE has accessed. In this case, the data transmission path information may include only service transmission scheme information, and does not include first user plane network element information, and the control plane network element or the second control plane functional entity selects the first user plane network element information based on the service transmission scheme.

Further, if the first device is a third-party server, the operation that the third-party server sends the determined data transmission path information to a control plane network element the UE has accessed or a second control plane functional entity includes: the third-party server sends the determined data transmission path information to a control plane network element the UE has accessed or a second control plane functional entity through a capability open platform.

At S403, the second control plane functional entity determines to adopt a user plane scheme based on the service related information of the UE, and determines information related to a first user plane network element accessed by the UE and a QoS policy corresponding to the service related information.

Here, the second control plane functional entity queries a user plane scheme and first user plane network element information corresponding to the service related information of the UE locally or from a database, a policy server, a DNS server, a third-party server, a capability open platform or an independent network element having a path selection function at a network side based on the acquired service related information.
