Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides an information processing method. FIG. 1 is a flow chart of an information processing method according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: a terminal receives a positioning signaling sent by first network equipment;
step 102: and when the received positioning signaling meets a preset condition, the terminal sends a notification message to second network equipment so as to switch the terminal to an idle state based on the notification message.
The technical solution of the present embodiment can be applied to various communication systems, such as a global System for Mobile communications (GSM) System, a Universal Mobile Telecommunications System (UMTS), a Long Term Evolution (LTE), or a 5G System. Illustratively, a communication system may include a network device and a terminal, and the network device may be a device communicating with the terminal.
In this embodiment, the first network device is a network entity device capable of implementing a positioning function. As an example, in an Evolved Packet System (EPS) network, the first network device may be an Evolved Serving Mobile Location Center (E-SMLC), but the first network device in this embodiment is not limited to the E-SMLC, and other network entity devices capable of implementing a Location function may also be the first network device in this embodiment.
In this embodiment, the second network device may be an access network device, and may also be a core network device related to a positioning function. As an example, the second network device may be a base station connected to the terminal, such as an evolved node b (eNB); as another example, the second network device may also be an MME, but the second network device is not limited to be an MME in this embodiment, and other core network devices related to the positioning function may also be the second network device described in this embodiment.
In this embodiment, the terminal is an internet of things terminal, for example, an NB-IoT terminal. The terminal of this embodiment is a low power consumption terminal, and can perform positioning related measurement only in an IDLE state (IDLE state).
In an optional embodiment of the present invention, the determining that the received positioning signaling satisfies the preset condition includes: judging that the received positioning signaling meets a preset condition when the first positioning signaling and the second positioning signaling are received; wherein the first positioning signaling is used for providing auxiliary positioning data; the second positioning signaling is used for requesting positioning information.
In this embodiment, the terminal obtains measurement configuration information configured by the first network device and related to positioning in a CONNECTED state (CONNECTED state), that is, the terminal receives a positioning signaling sent by the first network device; as an example, if the first network device is an E-SMLC, the positioning signaling reaches the terminal via transparent transmission of the MME and the base station.
As an implementation manner, the measurement configuration information sent by the first network device to the terminal may include multiple measurement configuration information, that is, the terminal may receive multiple positioning signaling sent by the first network device, and when the received positioning signaling meets a preset condition, the terminal determines that the terminal may switch to an idle state for positioning measurement.
In practical application, the multiple positioning signaling sent by the first network device to the terminal at least includes the first positioning signaling and the second positioning signaling, and when the terminal receives the first positioning signaling and the second positioning signaling (that is, both the first positioning signaling and the second positioning signaling are received), it is determined that the received positioning signaling meets the preset condition, and the terminal determines that the terminal can switch to an idle state for positioning measurement. The receiving order of the first positioning signaling and the second positioning signaling is not limited, and the terminal may receive the first positioning signaling first and then receive the second positioning signaling, or may receive the second positioning signaling first and then receive the first positioning signaling.
It should be noted that, if the terminal only receives the first positioning signaling or the second positioning signaling, it is determined that the received positioning signaling does not satisfy the preset condition, and the terminal does not send a notification message to the second network device; the terminal continues to wait until the second positioning signaling or the first positioning signaling is received.
As an example, the first positioning signaling is used to provide assistance-positioning data; the first Positioning signaling may be LTE Positioning Protocol (LPP) assistance Data provision (LPP providedassistance Data) signaling; the second positioning signaling is used for requesting positioning Information, and the second positioning signaling may be LPP positioning Information Request (LPP Request Location Information) signaling.
In an optional embodiment of the present invention, the sending, by the terminal, a notification message to a second network device to switch the terminal to an idle state based on the notification message includes: the terminal sends a first notification message to a base station so that the base station releases RRC connection with the terminal based on the first notification message.
The embodiment is applicable to a scenario in which the second network device is an access network device (e.g., a base station), and then the terminal determines that it can switch to an idle state, and sends the first notification message to the base station (i.e., the second network device), so that the base station (i.e., the second network device) releases an RRC connection with the terminal, i.e., releases an air interface connection with the terminal, and does not wait for the inactivity timer to time out and then release. As an example, the first notification message carries a Buffer Status Report (BSR) 0 field, which indicates that there is no data transmission within a preset time duration; and after the base station (namely the second network equipment) receives the first notification message and completes the data transmission, releasing the RRC connection with the terminal.
In another optional embodiment of the present invention, the terminal sends a second notification message to an MME, and the second notification message is transmitted to the MME via a base station, so that the MME instructs the base station to release an RRC connection with the terminal based on the second notification message; wherein the second notification message is a NAS message.
The embodiment is applicable to a scenario in which the second network device is a core network device (e.g., MME), and the terminal determines that the terminal can switch to the idle state, and then sends the second notification message to the MME (i.e., the second network device); and if the second notification message is an NAS message, the second notification message is transmitted to an MME through a base station. In this embodiment, the second notification message is used to indicate whether the current data is the last data to be transmitted; if the second notification message is used for indicating that the current data is the last transmitted data, the MME triggers the base station to release the RRC connection with the terminal after the current data transmission is completed based on the second notification message, that is, the MME triggers the base station to release the air interface connection with the terminal, and does not wait for the inactivity timer to be released after being overtime. As an example, the second notification message carries an indication identifier for indicating whether the current data is the last transmitted data, and the MME may determine whether the current data is the last transmitted data based on the indication identifier.
By adopting the technical scheme of the embodiment of the invention, the terminal can be switched to the idle state according to the self-judgment of the received positioning signaling, so that the terminal can perform positioning measurement in the idle state, and can enter the idle state without waiting for the timeout of the inactive timer of the base station, thereby greatly shortening the positioning time, and greatly reducing the positioning time delay of the terminal of the Internet of things and the power consumption of the terminal.
