Description

Information acquisition method and device, terminal equipment and network side equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to an information acquisition method, an information acquisition device, terminal equipment and network side equipment.

Background

The PIN (Personal IoT Network, personal internet of things) is a network based on and composed of a vast array of consumer internet of things devices. The internet of things devices can be wearable devices, such as cameras, headphones, watches, headphones, health monitors and the like, and can also be internet of things devices in the home, such as intelligent lamps, cameras, thermostats, door sensors, voice assistants, speakers, refrigerators, washing machines and the like. The user creates a personal networking network using all of these personal networking elements primarily at home or around the body. Generally, PINs are generally used in home, office, etc., and internet of things devices deployed in these scenes can be interconnected, communicate with each other, and acquire services, so that they are called personal networking. Meanwhile, it is also to be noted that the internet of things device in the PIN can access the 5G network, access other servers of the network or complete the service through the device with gateway function in the PIN by a certain mechanism and implementation.

Application functions (Application Function, AF) related to the PIN are not deployed in the 5G network at present, and therefore how to achieve information acquisition of the PIN without AF participation remains to be studied. For example, if the internet of things device in the PIN uses the 5G service through the personal internet of things element (PIN Element with Gateway Capability, PEGC) with network capability, the PEGC needs to establish a data channel for the PIN element to be used for the PIN service, and the PEGC needs to acquire PIN configuration information such as an IP address for the PIN element first, but how to acquire the PIN configuration information is not clear yet.

The information acquisition method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

In a first aspect, referring to fig. 2, a flowchart of an information obtaining method provided in an embodiment of the present application is shown. The method is applied to the personal networking element, as shown in fig. 2, and specifically can include:

step 201, a personal internet of things element sends a first indication to a first network side device/a second network side device, wherein the first indication is used for requesting personal internet of things configuration information;

step 202, the personal internet of things element receives first information, wherein the first information comprises personal internet of things configuration information of the first indication request;

wherein the first indication comprises at least one of:

a1, a personal Internet of things configuration information request;

a2, requesting an element address of the personal Internet of things;

a3, the capability indication of the personal Internet of things element is used for indicating that the personal Internet of things element has gateway capability.

It should be noted that, the personal internet of things Element (PIN) has gateway capability, and can provide connection with a 5G network for other PIN elements or provide a relay for communication between PIN elements. The personal internet of things element is used for routing traffic of other personal internet of things elements to a destination address, for example, one PIN is required to communicate with other PINs in the personal internet of things (Personal IoT Network, PIN), and routing can be performed through the personal internet of things element. The personal internet of things element may be a gateway device (PIN Element with Gateway Capability, PEGC) in a PIN. The personal internet of things element may also be the terminal device 11 with gateway capability in fig. 1, wherein the description of the terminal device 11 may be referred to the related description above, and will not be repeated here.

The first network side equipment has a session management function, and the second network side equipment has an access and mobility management function. Illustratively, the first network side device may be a session management function (Session Management Function, SMF) in the core network device shown in fig. 1, and the second network side device may be an access and mobility management function (Access and Mobility Management Function, AMF) in the core network device shown in fig. 1.

When the PIN element accesses the 5G network through the PEGC, the PEGC needs to obtain relevant configuration information of the PIN element from the network first, but in the related art, a solution for obtaining the PIN configuration information from the 5G network is not known for the PEGC.

In order to achieve that the PEGC obtains PIN configuration information from the 5G network without participation of AF or PINMF, the embodiment of the present application provides an information obtaining method. Specifically, the personal internet of things element directly sends a first indication to the first network side device (Session Management Function, SMF) or the second network side device (Access and Mobility Management Function, AMF), the first indication being used to request personal internet of things configuration information. Wherein the first indication may comprise at least one of A1 to A3.

Optionally, the sending, by the personal internet of things element, a first indication to the first network side device/the second network side device includes:

the personal Internet of things element sends a PDU (protocol data Unit) session establishment request message or a PDU session modification request message to first network side equipment, wherein the PDU session establishment request message or an extension protocol configuration option information element of the PDU session modification request message comprises a first indication; or,

the personal Internet of things element sends an uplink non-access layer transparent transmission message or a registration message to the second network side device, wherein the uplink non-access layer transparent transmission message or the registration message carries a newly added first information element, and the first information element comprises a first indication.

The information acquisition method provided by the embodiment of the application provides two acquisition modes of PIN configuration information. Mode one: the personal networking element sends a first indication to the SMF and receives PIN configuration information returned by the SMF; mode two: the personal networking element sends a first indication to the AMF and receives PIN configuration information returned by the AMF. The coding scheme of the first indication is also different for different receivers. In particular, the first indication may be included in an extended protocol configuration option information element of a PDU session establishment request message or a PDU session modification request message; or the first information element is included in the newly added first information element in the uplink non-access layer transparent transmission message or the registration message.

As an example, referring to fig. 3, an interaction schematic diagram of an information obtaining method provided in an embodiment of the present application is given. As shown in fig. 3, the personal internet of things element sends a PDU session establishment request or PDU session modification request (PDU session establishment/modification request) message to the SMF, the PDU session establishment request message or the extended protocol configuration option information element (extended Protocol Configuration Options Information Element, ePCO IE) of the PDU session modification request message containing the first indication. The SMF returns a PDU session establishment accept or PDU session modification command (PDU session establishment/modification accept) message to the personal internet of things element, the PDU session establishment accept message or PDU session modification command message carrying first information comprising PIN configuration information matching the first indication.

Optionally, the extended protocol configuration option information element includes a first container identifier added, where the first container identifier is used to indicate the first indication.

In the embodiment of the present application, a container identifier, that is, a first container identifier, may be newly added in the extended protocol configuration option information element of the PDU session establishment request message or the PDU session modification request message to indicate the first indication.

For example, there are a plurality of specific container identifiers in the Mobile Station (MS) to network direction, in this embodiment, one container identifier, that is, the first container identifier in this application, is added in the MS to network direction for carrying the first indication. The network side may determine that an individual persona networking element (e.g., PEGC) requests PIN configuration information based on the first container identifier. Illustratively, "004BH" is a newly added container identifier, i.e., a first container identifier in the present application, which identifies that the container carries a first indication, which may specifically include at least one of: PIN configuration information request, namely A1; a PIN element IP address request, namely A2; PEGC supports an indicator, i.e., A3.

As another example, referring to fig. 4, an interaction diagram of another information obtaining method provided in an embodiment of the present application is shown. As shown in fig. 4, the personal internet of things element sends an uplink non-access layer transparent transmission message or a registration message to the AMF, where the uplink non-access layer transparent transmission message or the registration message carries a first information element that is added, and the first information element includes a first indication. After the AMF receives the uplink non-access layer transparent transmission message or the registration message, the AMF sends a first instruction to the SMF through the second information, and the SMF returns first information matched with the first instruction to the AMF according to the first instruction. After the AMF receives the first information, the AMF sends a downlink non-access layer transparent transmission message or a registration message to the personal Internet of things element, wherein the downlink non-access layer transparent transmission message or the registration message carries the first information, and similarly, the first information comprises PIN configuration information matched with the first indication.

It can be understood that, in the interaction schematic diagram shown in fig. 4, the uplink non-access layer transparent transmission message or the registration message between the personal internet of things element and the AMF does not originally include an information element for requesting PIN configuration information, in order to obtain PIN configuration information, in this embodiment of the present application, the R18 standard may be modified, and a PIN configuration information element, that is, a first information element in this application, is newly added in the uplink non-access layer transparent transmission message or the registration message, where the first information element includes a first indication.

Referring to fig. 5, a schematic diagram of encoding a first information element according to an embodiment of the present application is provided. As shown in fig. 5, the first information element, i.e., the PIN configuration information element (PIN configuration IE) added in the uplink non-access stratum transparent transfer message or the registration message, includes a PIN configuration content length (Length of PIN configuration contents), a PIN configuration type (PIN configuration type), and PIN configuration content (PIN configuration contents). The PIN configuration content length is used for indicating the content length of the PIN configuration information, the PIN configuration content is used for indicating the PIN configuration information, and the PIN configuration type is used for indicating the configuration type of the personal networking element request. The PIN configuration type may include at least one of PIN configuration information (PIN configuration information), PIN element IP address (PIN devices IP address), and PEGC support index (PEGC support indicator). It is understood that the PIN configuration information corresponds to A1, the PIN element IP address corresponds to A2, and the PEGC support index corresponds to A3.

As an example, the PIN configuration type may be represented with a 3 byte octet code. For example: "000" represents PIN configuration information, "001" represents PIN element IP address, "011" represents PEGC support index. Other values may be spare.

When the PIN configuration information element is transmitted from the personal Internet of things element to the network, the length of the PIN configuration content length indication is 0, and the PIN configuration content field is null. If the PIN configuration content field is not empty, the PIN configuration information element should be ignored.

When the PIN configuration information element is transmitted from the network to the personal Internet of things element and the PIN configuration type is a PIN element IP address, the PIN configuration content field contains an IPv4/IPv6 address, and the IPv4/IPv6 address is encoded into a 128-bit address. When it is desired to contain multiple IPv4/IPv6 addresses, then more logical units with PIN configuration identifiers indicating IPv4/IPv6 addresses are used. When the PIN configuration type is PIN configuration information/PEGC support index, the PIN configuration content is beyond the 3GPP range.

After the personal internet of things element sends a first instruction to the first network side device or the second network side device, first information is received, and the first information contains personal internet of things configuration information requested by the first instruction. Specifically, in the interaction process shown in fig. 3, the personal internet of things element receives a PDU session establishment acceptance message or a PDU session modification command message returned by the SMF, where the PDU session establishment acceptance message or the PDU session modification command message carries first information. Or in the interaction process shown in fig. 4, the personal internet of things element receives a downlink non-access layer transparent transmission message or a registration message returned by the AMF, where the downlink non-access layer transparent transmission message or the registration message carries first information.

Through the interaction process shown in fig. 3 and fig. 4, the personal internet of things element can acquire PIN configuration information, so as to further assist the PINE to access the 5G network or communicate with other PIN elements.

Optionally, the first indication or the first information comprises at least one of the following bitfields:

b1, a first bit field, wherein the first bit field is used for indicating the content length of personal Internet of things configuration information;

b2, a second location field, wherein the second location field is used for indicating the configuration type of the personal Internet of things element request;

b3, a third bit field, wherein the third bit field is used for indicating personal Internet of things configuration information.

Wherein the configuration type may be at least one of A1 to A3.

In an embodiment of the present application, the first indication or the first information each comprises at least one bit field of B1 to B3. For example, if the first indication is included in the ePCO IE of the PDU session establishment request message or the PDU session modification request message, a container identifier, that is, the first container identifier in the present application, may be newly added in the ePCO IE, to indicate the first indication in the present application. The first container identifier may comprise at least one bit field of B1 to B3 according to the content of the first indication. Illustratively, the encoding of the container identifier may include three parts: the container ID (Container ID), the length of the container ID content (Length of container ID contents), and the container ID content (Container ID contents), in which in the embodiment of the present application, the container ID of the first container identifier corresponds to the second bit field, and the configuration type corresponding to the container identifier, that is, at least one of the first indications A1 to A3 indicated by the container identifier, may generally be directly used as the container ID; the length of the container ID content of the first container identifier corresponds to the first bit field and the container ID content corresponds to the third bit field.

Similarly, if the first indication is included in the first information element newly added in the uplink non-access stratum transparent transmission message or the registration message, the first information element may include at least one bit field in B1 to B3, and the content of each bit field in the first information element matches with the first indication. As shown in fig. 5, in the encoding of the first information element, the PIN configuration content length corresponds to the first bit field, the PIN configuration type corresponds to the second bit field, and the PIN configuration content corresponds to the third bit field.

In the uplink signaling, the first bit field indicates that the content length of the personal networking configuration information is 0, and the third bit field is null.

In uplink signaling, that is, when the first indication is transmitted from the personal internet of things element to the SMF or the AMF, since the PIN configuration information is not acquired at this time, the first bit field of the first indication, that is, the first container identifier or the first bit field of the first information element indicates a length of 0, and the third bit field is null. If the third bit field is not empty, the first container identifier or the first information element should be ignored.

In an optional embodiment of the present application, before the personal internet of things element sends the first indication to the first network side device/the second network side device, the method further includes: the personal internet of things element sends a second instruction to the first network side device, wherein the second instruction is used for requesting to establish a PDU session dedicated for transmitting personal internet of things signaling or personal internet of things protocol messages.

In this embodiment of the present application, a PDU session establishment request message or a PDU session modification request message transmitted between an element of the personal internet of things and the SAM for acquiring PIN configuration information is used to acquire PIN configuration information, which belongs to PIN signaling or PIN protocol messages. The personal networking element needs to establish a PDU session for transmitting PIN signaling or PIN protocol messages before sending the first indication. Specifically, the personal internet of things element sends a second indication to the SMF requesting establishment of a PDU session dedicated to transmitting PIN signaling or PIN protocol messages.

Optionally, the sending, by the personal internet of things element, a second indication to the first network side device includes:

step S11, the personal Internet of things element generates a PDU session establishment request message based on a data network name or single network slice selection auxiliary information associated with the personal Internet of things element, wherein an extension protocol configuration option information element of the PDU session establishment request message contains a second indication;

step S12, the personal Internet of things element sends the PDU session establishment request message to the first network side device.

The data network name associated with the PIN element may be a default data network name (default Data Network Name, default DNN) associated with the PIN element.

The personal networking element may generate a PDU session establishment request message based on the data network name or the single network slice selection assistance information (Single Network Slice Selection Assistance information, S-nsai) associated with the personal networking element, the extended protocol configuration option information element of the PDU session establishment request message including a second indication for indicating that the PDU session is dedicated to transmitting PIN signaling or PIN protocol messages. After receiving the PDU session establishment request message, the SMF establishes the PDU session according to the second instruction carried in the PDU session establishment request message. Specifically, the SMF may configure quality of service rules for personal internet of things elements, specifying a certain quality of service flow for transmitting PIN signaling or PIN protocol messages. The personal networking element transmits PIN signaling or PIN protocol messages using a specified quality of service stream after the PDU session establishment is successful.

Optionally, the extension protocol configuration option information element of the PDU session establishment request message includes a personal internet of things signaling flag, where the personal internet of things signaling flag is used to indicate that the PDU session establishment request message is used to request establishment of a PDU session dedicated to transmission of personal internet of things signaling or personal internet of things protocol messages.

In the embodiment of the application, when the personal internet of things element establishes a PDU session in the 5G network using the service quality flow for transmitting PIN signaling or PIN protocol messages, the personal internet of things element may set a PIN signaling flag in an extended protocol configuration option information element of a PDU session establishment request message, where the PIN signaling flag is used to instruct the network that the PDU session establishment request message is used to request establishment of a PDU session dedicated to transmitting PIN signaling or PIN protocol messages.

According to the information acquisition method provided by the embodiment of the application, the personal internet of things element can send a first indication to the first network side device/the second network side device, and the first indication specifically can comprise at least one of the following: a personal Internet of things configuration information request; a personal Internet of things element address request; the capability indication of the personal Internet of things element is used for indicating that the personal Internet of things element has gateway capability. The personal networking element may obtain PIN configuration information from the 5G network through the first indication, which is beneficial to the personal networking element to assist the PIN in accessing the 5G network or communicating with other PIN elements.

In a second aspect, referring to fig. 6, a flowchart of another information obtaining method provided in an embodiment of the present application is shown. The method is applied to the first network side device, as shown in fig. 6, and the method specifically may include:

Step 601, a first network side device receives a first instruction, wherein the first instruction is used for requesting personal networking configuration information;

step 602, the first network side device sends first information to a personal internet of things element or a second network side device, where the first information includes at least one of the following:

c1, personal Internet of things configuration information;

c2, an element address of the personal Internet of things;

c3, the capability indication of the personal Internet of things element is used for indicating that the personal Internet of things element has gateway capability.

The personal internet of things element has gateway capability, and can provide connection with a 5G network for other PIN elements or relay for communication among the PIN elements. The first network side equipment has a session management function, and the second network side equipment has an access and mobility management function. Illustratively, the first network side device may be a session management function (Session Management Function, SMF) in the core network device shown in fig. 1, and the second network side device may be an access and mobility management function (Access and Mobility Management Function, AMF) in the core network device shown in fig. 1.

The first indication comprises at least one of the foregoing A1 to A3, and the first information contains PIN configuration information requested by the first indication.

Optionally, the first network side device sends the first information to the personal internet of things element or the second network side device, including:

the first network side equipment sends a PDU session establishment acceptance message or a PDU session modification command message to the personal Internet of things element, and the PDU session establishment acceptance message or the extension protocol configuration option information element of the PDU session modification command message contains first information.

The information acquisition method provided by the embodiment of the application provides two acquisition modes of PIN configuration information. Mode one: the personal networking element sends a first indication to the SMF and receives first information returned by the SMF; mode two: the person networking element sends a first indication to the AMF and receives first information returned by the AMF. The sender is different, and the encoding mode of the first information is also different.

As an example, as shown in fig. 3, the personal internet of things element sends a PDU session establishment request message or a PDU session modification request message to the SMF, where the PDU session establishment request message or the extension protocol configuration option information element of the PDU session modification request message includes a first indication. The SMF returns a PDU session establishment acceptance message or a PDU session modification command message to the personal Internet of things element, wherein the PDU session establishment acceptance message or the extension protocol configuration option information element of the PDU session modification command message contains first information, and the first information is matched with the first indication.

Optionally, the extended protocol configuration option information element of the PDU session establishment acceptance message or the PDU session modification command message includes a second container identifier, where the second container identifier is used to indicate the first information.

In the embodiment of the present application, a container identifier, that is, a second container identifier in the present application, may be newly added to the PDU session establishment acceptance message or the PDU session modification command message to indicate the first information.

For example, there are a plurality of specific container identifiers in the network-to-MS direction, and in this embodiment, one container identifier, that is, the second container identifier in this application, is added in the network-to-MS direction to indicate the first information. The MS (e.g., PEGC) may determine the PIN configuration information based on the second container identifier. Illustratively, "004BH" is a newly added container identifier, that is, a second container identifier in the present application, where the identifier carries the first information in the container, and specifically may include at least one of the following: PIN configuration information, i.e., C1; the PIN element IP address, namely C2; PEGC supports an indicator, i.e., C3.

As another example, as shown in fig. 4, the personal internet of things element sends an uplink non-access layer transparent transmission message or a registration message to the AMF, where the uplink non-access layer transparent transmission message or the registration message carries a first information element that is added, and the first information element includes a first indication. After the AMF receives the uplink non-access layer transparent transmission message or the registration message, the AMF sends a first instruction to the SMF through the second information, and the SMF returns first information matched with the first instruction to the AMF according to the first instruction. After the AMF receives the first information, the AMF sends a downlink non-access layer transparent transmission message or a registration message to the personal Internet of things element, wherein the downlink non-access layer transparent transmission message or the registration message carries a newly added second information element, and the second information element contains the first information.

It may be understood that, the downlink non-access layer transparent transmission message or the registration message between the personal internet of things element and the AMF does not originally include an information element for requesting PIN configuration information, in this embodiment of the present application, the R18 standard may be modified, and a PIN configuration information element, that is, a second information element in this application, is newly added in the downlink non-access layer transparent transmission message or the registration message, where the second information element includes the first information.

Wherein the configuration type may be at least one of A1 to A3.

In an embodiment of the present application, the first indication or the first information each comprises at least one bit field of B1 to B3. For example, if the first information is included in an extended protocol configuration option information element of a PDU session establishment acceptance message or a PDU session modification command message, the extended protocol configuration option information element has a container identifier newly added, that is, the second container identifier in the present application includes at least one of bit fields B1 to B3, and the contents in the respective bit fields match the first indication. Similarly, if the first information is included in a second information element newly added in the downlink non-access stratum transparent transmission message or the registration message, the second information element includes at least one bit field from B1 to B3, and the content in each bit field matches with the first indication.

In the uplink signaling, the content length of the PIN configuration information is indicated as 0 by the first bit field, and the third bit field is null. In the uplink signaling, that is, when the first indication is transmitted from the personal internet of things element to the SMF or the AMF, since the PIN configuration information is not acquired at this time, the first bit field of the first indication, that is, the first container identifier or the first bit field of the first information element indicates that the content length of the PIN configuration information is 0, and the third bit field is null. If the third bit field is not empty, the second container identifier or the second information element should be ignored.

When the first indication comprises at least one of a PIN configuration information request, a PIN element address request, said personal internet of things element capability indicator, the content field of the second container identifier or the second information element, i.e. the second location field, contains PIN configuration information or a PIN element address. The PIN configuration information or PIN element address is encoded as a 128-bit address according to IETF RFC 4291[99 ]. When multiple PIN configuration information or PIN element addresses need to be included in the second bit field, then more logic units with container identifiers indicating PIN configuration information or PIN element addresses are used.

Optionally, before the first network side device sends the first information to the personal internet of things element or the second network side device, the method further includes:

Step S21, the first network side equipment receives a second instruction, wherein the second instruction is used for requesting to establish a PDU session special for transmitting personal networking signaling or personal Internet of things protocol messages;

step S22, the first network side equipment establishes a PDU session according to the second instruction, wherein the PDU session is used for transmitting personal networking signaling or personal Internet of things protocol messages.

In the embodiment of the application, after the SMF receives the second indication sent by the personal networking element, a PDU session is established according to the second indication. The personal internet of things element may generate a PDU session establishment request message according to a default data network name or single network slice selection auxiliary information associated with the personal internet of things element, where an extended protocol configuration option information element of the PDU session establishment request message includes a second indication for indicating that the PDU session is exclusively used for transmitting PIN signaling or PIN protocol messages. After receiving the PDU session establishment request message, the SMF establishes the PDU session according to the second instruction carried in the PDU session establishment request message.

Specifically, the SMF configures quality of service rules for personal internet of things elements, specifying a certain quality of service flow for transmitting PIN signaling or PIN protocol messages. The personal networking element transmits PIN signaling or PIN protocol messages using a specified quality of service stream after the PDU session establishment is successful.

In the embodiment of the present application, the PIN configuration information may be preconfigured in the SMF, and the SMF obtains the PIN configuration information from the local and generates the first information before sending the first information. Alternatively, the SMF may also obtain PIN configuration information from a unified data management function (Unified Data Management, UDM) or policy control function (Policy Control Function, PCF) based on gateway identification or gateway capabilities of the personal internet of things element.
