Description

This application claims priority to Chinese Patent Application No. 202310830085.5, filed with the China National Intellectual Property Administration on July 6, 2023 and entitled "IDENTIFIER ASSIGNMENT METHOD AND APPARATUS FOR PERSONAL IOT NETWORK, AND NETWORK SIDE DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application belongs to the technical field of communication, and specifically relates to an identifier assignment method and apparatus for a personal IoT network, and a network side device. BACKGROUND A personal IoT network (Personal IoT network, PIN) is a network that is based on a large quantity of added consumer IoT devices and that is formed by and derived from these IoT devices. A user mainly creates a personal IoT network by using all these personal IoT devices at home or around a body, for example, a wearable device or an IoT device at home. Usually, the PIN is generally used in scenarios such as a home and an office. IoT devices deployed in these scenarios may implement interconnection, mutual communication, and service acquisition. In addition, the IoT device in the PIN may be implemented by using a mechanism, and access a 5G network, access another server of the network, or complete a service by using a PIN element with gateway capability (PIN element with gateway capability, PEGC) in the PIN. When the PEGC uses a user equipment (User Equipment, UE) route selection policy (UE Route Selection Policy, URSP) protocol to route PIN traffic to a protocol data unit (Protocol Data Unit, PDU) session, routing needs to be performed based on a PIN identifier. Then, a method for assigning the PIN identifier is not provided in related technologies, and thus the PIN traffic cannot be routed. SUMMARY Embodiments of this application provide an identifier assignment method and apparatus for a personal IoT network, and a network side device, to implement identifier assignment of a PIN. According to a first aspect, an identifier assignment method for a personal IoT network is provided. The method includes: assigning, by a first network element, a PIN identifier to a target PIN, where the PIN identifier is unique in the first network element; and sending or configuring, by the first network element, the PIN identifier of the target PIN to a second network element. According to a second aspect, an identifier assignment apparatus for a personal IoT network is provided, applied to a first network element. The apparatus includes: an assignment module, configured to assign a PIN identifier to a target PIN, where the PIN identifier is unique in the first network element; and a processing module, configured to send or configure the PIN identifier of the target PIN to a second network element. According to a third aspect, a network side device is provided. The network side device includes a processor and a memory, the memory stores a program or instructions runnable on the processor, and when executed by the processor, the program or the instructions implement steps of the method according to the first aspect. According to a fourth aspect, a readable storage medium is provided. The readable storage medium stores a program or instructions, and when executed by the processor, the program or instructions implement steps of the method according to the first aspect. According to a fifth aspect, a chip is provided. The chip includes a processor and a communication interface. The communication interface is coupled to the processor. The processor is configured to run a program or instructions to implement steps of the method according to the first aspect. In this embodiment of this application, the first network element assigns the PIN identifier to the target PIN, where the PIN identifier is unique in the first network element; and then, the first network element sends or configures the PIN identifier of the target PIN to the second network element. Because the PIN identifier is unique in the first network element, the first network element sends or configures the PIN identifier of the target PIN to the second network element, so that the second network element can identify the target PIN.
