Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for calling a terminal, and a network device.
Background
With the introduction of a new air interface (NR) system, a new state is defined for a terminal, which is different from an idle state (idle) in the LTE system and a connected active state (connected active) in the LTE system, and is an inactive (inactive) state.
In a Long Term Evolution (LTE) system, for a connected terminal (UE), a Cell Radio Network Temporary Identifier (C-RNTI) of the UE is scrambled on a Physical Downlink Control Channel (PDCCH) to implement scheduling of the UE.
For an idle-state UE, when downlink data needs to be sent to the idle-state UE, a Mobility Management Entity (MME) sends a paging message to all base stations in all Tracking areas (Tracking areas) registered by the UE, and the base stations send a paging message through an air interface to page the UE. The UE in idle state may monitor whether there is a PDCCH scrambled with a Radio network temporary identity P-RNTI (the identity is a common identity), and if a paging message transmitted on a corresponding data channel (PDSCH) includes a terminal identity (UE ID), the UE may initiate a Radio Resource Control (RRC) connection establishment procedure after receiving the paging message, so as to receive downlink data.
However, the paging message can only be used for paging the idle-state UE, and the paging message can only realize the calling to the idle-state UE by scrambling the PDCCH channel with the common P-RNTI, and cannot call the newly added inactive-state UE.

Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment
As shown in fig. 1, a first embodiment of the present invention provides a method for calling a terminal, which is applied to a terminal (e.g., a smart phone, a tablet computer, etc.), wherein the method includes:
The first identifier of the terminal is an identifier when the terminal is in an inactive state in a current cell, for example, an inactive-state radio network temporary identifier (inactive-RNTI), and the first identifier is a terminal-specific identifier. In addition, the control channel may be a PDCCH, or may also be a control channel that is newly added for the terminal to monitor whether there is a call for the terminal.
It should be noted that the paging inactive ue (paging for inactive ue) message is a message that is assembled and issued by the network device itself and is used for calling the terminal, and may have different names in different communication technology standards. The network device may be a base station, and it is understood that, in the embodiment of the present invention, the specific form of the network device is not limited, for example, the network device may also be a core network control node, and meanwhile, the terminal in the embodiment of the present invention should be a terminal in an inactive state.
The content of the paging non-activated state terminal message comprises a second identifier for uniquely identifying the terminal in the whole network, so that the terminal can accurately determine the terminal as a called terminal, and the call of the network equipment to the terminal is completed. The second identifier may be an International Mobile Subscriber Identity (IMSI) or a temporary terminal identity (S-TMSI).
It should be noted that after the step 102 is executed, the method further includes a step of performing relevant operations according to the content of the paging inactive state terminal message, that is, it corresponds to a step of responding to the paging inactive state terminal message, so as to complete the purpose of the call. The related operation is related to the purpose of the network device calling the terminal, and may specifically be to perform state transition (for example, switching from an inactive state to a connected state), receive downlink data sent by the network device, initiate connection establishment, and the like.
In the first embodiment of the present invention, the content of the paging inactive state terminal message may further include: a cell identity on which the terminal camps when entering an RRC connected state prior to the inactive state and/or a message indicating a reason for the network device to call the terminal.
The cell identifier has the following main functions: and if the terminal determines that the cell corresponding to the cell identifier is the cell in which the terminal resides in the RRC connected state before the terminal enters the inactive state, the network device may obtain more information related to the terminal from the cell corresponding to the cell identifier, which is helpful for the network device to perform subsequent related operations on the terminal, such as data transmission and the like.
The main roles of the message indicating the reason for the network device to call the terminal are: the terminal can conveniently perform related operations according to the content of the paging non-activated state terminal message, such as state conversion, receiving downlink data issued by the network equipment and the like.
Therefore, in the first embodiment of the present invention, a terminal in an inactive state monitors whether a control channel scrambled by using a first identifier of the terminal (the first identifier of the terminal is an identifier when the terminal is in an inactive state in a current cell) exists and receives a paging inactive state terminal message issued by a network device, and when the control channel scrambled by using the first identifier of the terminal is monitored and the paging inactive state terminal message is received, a second identifier for uniquely identifying the terminal in the entire network in the content of the paging inactive state terminal message is obtained by parsing, so that the network device completes a call to the terminal in the inactive state, and implements subsequent data transmission, i.e., the network device and the terminal can complete subsequent scheduling through a consistent process.
Second embodiment
As shown in fig. 2, a second embodiment of the present invention provides a method for calling a terminal, which is applied to a terminal (e.g., a smart phone, a tablet computer, etc.), wherein the method includes:
The first identifier of the terminal is an identifier when the terminal is in an inactive state in the current cell, for example, an inactive state radio network temporary identifier, and the first identifier is a terminal-specific identifier. In addition, the control channel may be a PDCCH, or may also be a control channel that is newly added for the terminal to monitor whether there is a call for the terminal.
It should be noted that the network device may be a base station, and it is to be understood that, in the embodiment of the present invention, the specific form of the network device is not limited, and for example, the network device may also be a core network control node. Meanwhile, the terminal in the second embodiment of the present invention should be a terminal in an inactive state.
The content of the paging non-activated state terminal message comprises a second identifier for uniquely identifying the terminal in the whole network, so that the terminal can accurately determine the terminal as a called terminal, and the call of the network equipment to the terminal is completed. The second identifier may be an IMSI or an S-TMSI.
In the second embodiment of the present invention, after the step 202 is executed, the method further includes a step of performing relevant operations according to the content of the paging inactive state terminal message, that is, the method further includes a step of responding to the paging inactive state terminal message, so as to complete the purpose of the call. The related operation is related to the purpose of the network device calling the terminal, and may specifically be to perform state transition (for example, switching from an inactive state to a connected state), receive downlink data sent by the network device, initiate connection establishment, and the like.
The high-level signaling may be RRC signaling or signaling carried by a protocol data Unit (MAC PDU). And the network equipment assembles the content of the paging non-activated state terminal message into a high-level signaling to send when sending the paging non-activated state terminal message. Therefore, for the terminal, the content of the paging non-activated state terminal message can be obtained by analyzing the high-layer signaling.
In the second embodiment of the present invention, the content of the paging inactive state terminal message may further include, in addition to the second identifier: a cell identity on which the terminal camps when entering an RRC connected state prior to the inactive state and/or a message indicating a reason for the network device to call the terminal. The function of the cell identifier and the message for indicating the reason for the network device to call the terminal is described in detail in the first embodiment, and is not described herein again to avoid repetition.
In the second embodiment of the present invention, when the network device issues the paging non-activated state terminal message through the higher layer signaling, the network device may also carry downlink resources for downlink data packet transmission or uplink resources for the terminal to initiate a random access process in the higher layer signaling. Therefore, there are two specific implementation manners for acquiring the content of the paging non-activated state terminal message by analyzing the high-level signaling in step 202. The first specific implementation manner is as follows: acquiring the content of the paging non-activated state terminal message and downlink resources for downlink data packet transmission by analyzing the high-level signaling; the second specific implementation manner is as follows: by analyzing the high-level signaling, the content of the paging non-activated state terminal message and the uplink resource used for the terminal to initiate the random access process are obtained, so that the terminal can correspondingly send or receive the possible subsequent resources according to the content of the paging non-activated state terminal message. It should be noted that, if a downlink resource used for downlink data packet transmission or an uplink resource used for a terminal to initiate a random access process needs to be carried in a higher layer signaling, the higher layer signaling may be a signaling carried in a MAC PDU.
The interaction process between the terminal in the inactive state and the network device is briefly described here, and specifically, when the network device calls the terminal by issuing a paging inactive state terminal message, the interaction process between the terminal and the network device is as shown in fig. 3.
It can be seen that, in the second embodiment of the present invention, a terminal in an inactive state monitors whether a control channel scrambled by using a first identifier of the terminal (the first identifier of the terminal is an identifier when the terminal is in an inactive state in a current cell) exists and receives a paging inactive state terminal message issued by a network device, and when the control channel scrambled by using the first identifier of the terminal is monitored and the paging inactive state terminal message is received, obtains a second identifier for uniquely identifying the terminal in the content of the paging inactive state terminal message in the whole network by analyzing a high-level signaling, so that the network device completes a call to the terminal in the inactive state, and implements subsequent data transmission, i.e., the network device and the terminal can complete subsequent scheduling through a consistent process.

Fifth embodiment
The first to fourth embodiments respectively describe the method for calling a terminal and the terminal of the present invention with respect to a terminal side, and the following embodiments further describe the method for calling a terminal on a network device side with reference to the accompanying drawings and specific application scenarios.
As shown in fig. 7, a fifth embodiment of the present invention provides a method for calling a terminal, which is applied to a network device, and includes:
The first identifier of the terminal is an identifier when the terminal is in an inactive state in the current cell, such as an inactive-RNTI, and the first identifier is a terminal-specific identifier. In addition, the control channel may be a PDCCH, or may also be a control channel that is newly added for the terminal to monitor whether there is a call for the terminal. In addition, the content of the paging non-activated state terminal message includes a second identifier for uniquely identifying the terminal in the whole network, and the second identifier may be an IMSI or an S-TMSI.
It should be noted that the network device may be a base station, and it is to be understood that, in the embodiment of the present invention, the specific form of the network device is not limited, for example, it may also be a core network control node, and meanwhile, the terminal in the embodiment of the present invention should be a terminal in an inactive state. It should be further noted that, in step 701, scrambling the control channel by using the first identifier of the terminal does not have a strict sequence with obtaining the paging non-activated state terminal message, and the scrambling and obtaining may be performed synchronously.
In the fifth embodiment of the present invention, there are two specific implementation manners for detecting that the preset message sending condition of the paging inactive state terminal is satisfied in step 701. The first specific implementation manner is as follows: if detecting that downlink data aiming at the terminal in the inactive state arrives, determining that the preset message sending condition of the terminal in the paging inactive state is met; the second specific implementation manner is as follows: if the sending period of the paging non-activated state terminal message is detected to arrive, the condition that the preset paging non-activated state terminal message sending condition is met is determined to be detected, so that the network equipment can complete the call to the terminal in time, and the subsequent data sending is facilitated.
In a fifth embodiment of the present invention, the paging inactive state terminal message is generated by the network device itself. Meanwhile, since the content of the paging non-activated state terminal message may include, in addition to the second identifier: a cell identity on which the terminal camps when entering an RRC connected state prior to the inactive state and/or a message indicating a reason for the network device to call the terminal. Therefore, the specific implementation manners of acquiring the paging non-activated state terminal message in step 701 include the following four manners:
the first specific implementation mode is as follows: and assembling the second identifier to generate a paging non-activated state terminal message.
The second specific implementation manner is as follows: and assembling the second identifier and the cell identifier which resides in the RRC connected state before the terminal enters the inactive state to generate a paging inactive state terminal message.
The third specific implementation mode is as follows: and assembling the second identifier and a message for indicating the reason for the network equipment to call the terminal to generate a paging non-activated state terminal message.
The fourth specific implementation manner is as follows: and assembling the second identifier, the cell identifier in which the terminal resides when entering the RRC connected state before the inactive state, and a message for indicating the reason for the network device to call the terminal, and generating a paging inactive state terminal message.
The cell identifier has the following main functions: and if the terminal determines that the cell corresponding to the cell identifier is the cell in which the terminal resides in the RRC connected state before the terminal enters the inactive state, the network device may obtain more information related to the terminal from the cell corresponding to the cell identifier, which is helpful for the network device to perform subsequent related operations on the terminal, such as data transmission and the like.
The main roles of the message indicating the reason for the network device to call the terminal are: the terminal can conveniently perform related operations according to the content of the paging non-activated state terminal message, such as state conversion, receiving downlink data issued by the network equipment and the like. It should be noted that, if the terminal performs the relevant operation according to the content of the paging inactive state terminal message, the network device will also correspondingly perform the corresponding operation, for example, issue the downlink data.
It should be further noted that, no matter which of the above four specific implementation manners is adopted to obtain the paging non-activated state terminal message, when the content of the paging non-activated state terminal message is assembled, the network device needs to assemble the content of the paging non-activated state terminal message according to the format (e.g. coding manner) requirement of the high-level signaling, so as to be convenient for being subsequently issued to the terminal through the high-level signaling. Meanwhile, because there are various forms of the higher layer signaling (for example, signaling carried by RRC signaling MAC PDU), the network device needs to determine which specific higher layer signaling is well assembled and then issued before assembling.
In a fifth embodiment of the present invention, a specific implementation manner of issuing a paging non-activated state terminal message to a terminal in step 702 is as follows: and sending a paging non-activated state terminal message to the terminal through a high-level signaling. The high-level signaling may be RRC signaling or signaling carried by MAC PDU.
Further, when the network device issues the paging inactive state terminal message through the high-level signaling, the network device may also carry downlink resources for downlink packet transmission or uplink resources for the terminal to initiate a random access process in the high-level signaling. Therefore, the specific implementation of sending the paging non-activated state terminal message to the terminal through the high-level signaling may be as follows: through high-level signaling, sending a paging non-activated state terminal message and downlink resources for downlink data packet transmission to a terminal; or, through high-level signaling, sending a paging non-activated state terminal message and uplink resources for the terminal to initiate a random access process to the terminal. It should be noted that, if a downlink resource for downlink data packet transmission or an uplink resource for a terminal to initiate a random access process needs to be carried in a higher layer signaling, the higher layer signaling may be a signaling carried in an MAC PDU.
Therefore, in the fifth embodiment of the present invention, when detecting that a preset condition for sending a paging inactive state terminal message is satisfied, a network device scrambles a control channel by using a first identifier of a terminal (the first identifier of the terminal is an identifier when the terminal is in an inactive state in a current cell), acquires a paging inactive state terminal message, and then, in an area on a radio access network side where location information of the terminal is stored, sends the paging inactive state terminal message to the terminal, so that the terminal in the inactive state acquires a second identifier for uniquely identifying the terminal in the whole network from the paging inactive state terminal message, thereby enabling the network device to complete a call to the terminal in the inactive state, and implement subsequent data sending.
