Description

Paging monitoring method, device, system and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a paging monitoring method, apparatus, system, and storage medium.

Background

When Core network equipment in an Evolved Packet Core (EPC) needs to send data or signaling to a terminal, or needs to be reattached to the terminal, the Core network equipment may initiate paging, and the Core network equipment initiates a paging process by sending a paging message to access network equipment. When the terminal is in a radio resource control-IDLE (RRC _ IDLE) or radio resource control-deactivated (RRC _ INACTIVE) state, the terminal needs to monitor paging because the core network device may page the terminal.

As a special terminal, a Wearable Device (WD) has a lower performance than a terminal such as a mobile phone, and in order to reduce power consumption of the Wearable Device. When the wearable device is in the RRC _ IDLE or RRC _ INACTIVE state, the terminal paired with the wearable device may listen for pages instead of the wearable device, such as a cell phone. After monitoring the paging, the terminal paired with the wearable device forwards the paging to the wearable device through a Long Term Evolution (LTE) technology, a New Radio (NR) technology, bluetooth, a Wireless Fidelity (WiFi) technology, or other communication methods, or notifies the wearable device of the paging. However, in some scenarios, a terminal paired with a wearable device may not necessarily listen for a page instead of the wearable device, or the wearable device may not necessarily need the terminal to listen for a page instead of the wearable device.

When the wearable device is in the RRC _ IDLE or RRC _ INACTIVE state, the wearable device may be listened to for paging through a terminal paired with the wearable device, such as a cell phone, which may be referred to as the cell phone taking over or proxying paging of the wearable device.

From the perspective of the core network, when the first terminal is in the RRC _ INACTIVE state, it is the same as the second terminal in the connected state.

The initiating conditions of the RRC connection release are: when the first terminal has no data transmission, the network device initiates the RRC connection release of the first terminal.

In one possible design, the first terminal may periodically determine the current state, for example: the first terminal judges the current state every 5 minutes or 10 minutes, and the state comprises the following steps: RRC _ IDLE state, RRC _ INACTIVE state, or RRC connection release state.

In case two and case five, the current serving cell of the first terminal refers to a cell in which the first terminal currently camps. The current serving cell of the second terminal refers to a cell in which the second terminal currently resides.

The user command in case four, case five and case six may be a voice command of the user or a text command input by the user, or a user operation on software or hardware on the first terminal, such as: the user instruction may be a pressing operation of a button of the first terminal by the user, or the like. Alternatively, the user instruction may be a click, touch or slide operation of a virtual key on the first terminal interface by the user, or the like.

It should be noted that, for the fourth case, when the first terminal is in the RRC _ IDLE state, the RRC _ INACTIVE state, or the RRC connection release state, the first terminal may push a prompt message, where the prompt message is used to prompt the user that the first terminal is in the RRC _ IDLE state, the radio resource control-deactivation RRC _ INACTIVE state, or the RRC connection release state. For example: fig. 3A is an interface diagram of a first terminal according to an embodiment of the present application, where as shown in fig. 3A, a prompt message currently pushed by the first terminal is used to prompt a user that the first terminal is currently in an RRC _ IDLE state, and fig. 3B is an interface diagram of a first terminal according to another embodiment of the present application, where as shown in fig. 3B, a prompt message currently pushed by the first terminal is used to prompt the user that the first terminal is currently in an RRC _ INACTIVE state. Based on this, the user can input the user instruction to indicate that the second terminal is required to perform paging listening instead of the first terminal.

For the fifth case, when the first terminal is in the RRC _ IDLE state, the RRC _ INACTIVE state, or the RRC connection release state, and the current serving cells of the first terminal and the second terminal are the same, the first terminal may push a prompt message, where the prompt message is used to prompt the user that the first terminal is in the RRC _ IDLE state, the radio resource control-deactivation RRC _ INACTIVE state, or the RRC connection release state. For example: as shown in fig. 3A, the first terminal is currently pushed a prompt message to prompt the user that the first terminal is currently in the RRC _ IDLE state, and as shown in fig. 3B, the first terminal is currently pushed a prompt message to prompt the user that the first terminal is currently in the RRC _ INACTIVE state. Based on this, the user can input the user instruction to indicate that the second terminal is required to perform paging listening instead of the first terminal.

For the sixth case, when the first terminal is in the RRC _ IDLE state, the RRC _ INACTIVE state, or the RRC connection release state, and the distance between the first terminal and the second terminal is smaller than the distance threshold, the first terminal may push a prompt message, where the prompt message is used to prompt the user that the first terminal is in the RRC _ IDLE state, the radio resource control-deactivation RRC _ INACTIVE state, or the RRC connection release state. For example: as shown in fig. 3A, the first terminal is currently pushed a prompt message to prompt the user that the first terminal is currently in the RRC _ IDLE state, and as shown in fig. 3B, the first terminal is currently pushed a prompt message to prompt the user that the first terminal is currently in the RRC _ INACTIVE state. Based on this, the user can input the user instruction to indicate that the second terminal is required to perform paging listening instead of the first terminal.

In the third and sixth cases, the distance threshold may be determined by the first terminal or the second terminal, and if the distance threshold is determined by the second terminal, the second terminal needs to send the distance threshold to the first terminal, so that the first terminal determines whether it meets the first condition. The distance threshold may be 5 meters, 10 meters, or 20 meters, which is not limited in this application.

To sum up, an embodiment of the present application provides a paging monitoring method, where when a first terminal meets a first condition, the first terminal sends first indication information to a second terminal, where the first indication information is used to indicate that the second terminal needs to replace the first terminal for paging monitoring; and the first terminal receives second indication information sent by the second terminal. Optionally, the first condition comprises: the first terminal is in an RRC IDLE state or an RRC INACTIVE state or an RRC connection release state. That is, the first terminal does not need the second terminal to perform paging monitoring instead of the first terminal under any condition, and on the contrary, if the first condition is not satisfied, the first terminal can perform paging monitoring by itself, thereby improving the flexibility of paging monitoring.

Optionally, the first condition comprises: the time length of the first terminal in the RRC _ IDLE state, the RRC _ INACTIVE state or the RRC connection release state reaches a preset time length. That is, the first terminal does not need the second terminal to perform paging monitoring instead of the first terminal under any condition, and on the contrary, if the first condition is not satisfied, the first terminal can perform paging monitoring by itself, thereby improving the flexibility of paging monitoring.

In any of the above embodiments it was described that when the first terminal satisfies the first condition, the first terminal needs the terminal instead to listen for pages. It will be provided below that the first terminal may perform paging listening by itself when the first terminal satisfies the second condition. It should be noted that the embodiment of the present application may be further executed on the basis of any one of the above embodiments, or may be executed alone, or the embodiment of the present application is executed first and then any one of the above embodiments is executed, which is not limited herein.

The application scenarios of the embodiments of the present application can be as follows, but are not limited to the following.

The application scene one: the first terminal and the second terminal have information interaction, and the information is used for the second terminal to judge whether to replace the first terminal to carry out paging monitoring.

Application scenario two: the second terminal is performing paging listening instead of the first terminal.

In conjunction with the above application scenarios, a paging listening method is introduced below. Specifically, fig. 4 is an interaction flowchart of a paging listening method according to another embodiment of the present application, and as shown in fig. 4, a network element involved in the method includes: a first terminal and a second terminal, on the basis of the previous embodiment, the method includes the following steps:

step S41: and when the first terminal meets the second condition, the first terminal sends third indication information to the second terminal, wherein the third indication information is used for indicating that the second terminal is not required to replace the first terminal for paging monitoring.

Step S42: the first terminal listens for pages.

In one possible design: the second condition includes that the first terminal cannot camp on the current serving cell of the second terminal.

In one possible design: the second condition includes a Tracking Area Update (TAU) failure by the first terminal in a current serving cell of the second terminal.

In one possible design: the second condition includes that the first terminal fails to track area update TAU for a preset number of times in a current serving cell of the second terminal.

In one possible design: the second condition includes the first terminal being in an RRC connected state.

In one possible design: the second condition includes that the time length of the first terminal in the RRC connection state reaches a preset time length.

In one possible design: the second condition includes the first terminal being switched from the RRC-IDLE state or the RRC-INACTIVE state to the RRC-connected state.

In LTE, a first terminal first performs PLMN (Public Land Mobile Network) selection after being powered on. Once the first terminal selects a PLMN, the first terminal will perform cell selection to select a suitable cell belonging to the PLMN to camp on. Wherein the first terminal selects a suitable cell based on the cell selection criterion. The current standard has defined cell selection criteria S as follows:

srxlev >0 and Squal >0

Wherein Srxlev ═ Q_rxlevmeas-(Q_rxlevmin+Q_{rxlevminoffset})-Pcompensation-Qoffset_temp

Squal＝Q_qualmeas-(Q_qualmin+Q_{qualminoffset})-Qoffset_temp

Srxlev and Squal are values based on Reference Signal Received Power (RSRP) of the cell and Reference Signal Received Quality (RSRQ) of the cell measured by the first terminal, respectively. Q_rxlevmeasIs the current serving cell received power, Q, measured by the first terminal_qualmeasRSRQ of a cell measured for the first terminal; q_rxlevminFor indicating the minimum reception level required in the cell measured by the first terminal. Q_rxlevminThe size of the value can be set by the networkAnd preparing the configuration. Q_qualminFor indicating the minimum required quality level in the cell as measured by the first terminal. Q_rxlevminThe size of the value may be configurable by the network device. Q_{rxlevminoffset}For indicating to Q when a first terminal is camped on a Visited Public Land Mobile Network (VPLMN) searching for a high priority PLMN_rxlevminThe offset is performed. Q_{qualminoffset}For indicating to Q when a first terminal is camped on a Visited Public Land Mobile Network (VPLMN) searching for a high priority PLMN_qualminThe offset is performed. Pcompensation is according to P_EMAX1，P_EMAX2And P_PowerClassAnd (4) determining. P_EMAX1And P_EMAX2Is configured by a network device, P_PowerClassIs defined in the standard protocol and is the maximum uplink transmission power determined by the first terminal power priority. Qoffset_tempIs an offset configured by the network device. Alternatively, in the definition of Srxlev and Squal, in some cases, in addition to Q_rxlevmeasAnd Q_qualmeasParameters other than these may not be present. The RSRP of a cell and the RSRQ of a cell are determined from a cell-specific reference signal (CRS). In LTE, the RSRP of a cell is the average power over Resource Elements (REs) carrying CRS within the measurement bandwidth. RSRP is used to represent the received power of the measured signal. The RSRQ is used to represent the Received quality of the measured Signal and may be determined according to the RSRP and a Received Signal Strength Indicator (RSSI).

Based on the above, when the current serving cell of the first terminal at the second terminal does not satisfy the above-mentioned cell selection criterion S, it cannot camp on the current serving cell of the second terminal.

In one possible design: the second condition includes: the first terminal fails a Tracking Area Update (TAU) in the current serving cell of the second terminal.

As described above, in one possible design: the second condition includes that the time length of the first terminal in the RRC connection state reaches a preset time length. The preset time period may be 20 seconds, 30 seconds, etc., which is not limited.

As described above, in yet another possible design: the first terminal is switching from an RRC-IDLE state or an RRC-INACTIVE state to an RRC-connected state.

When the first terminal is initially accessed, establishing wireless connection: the first terminal switches from the RRC _ IDLE state to the RRC connected state.

The first terminal switches from the RRC-INACTIVE state to the RRC-connected state, which is divided into two cases:

the first condition is as follows: the method for switching the RRC-ACTIVE state to the RRC connected state includes the following steps:

step 1: the first terminal recovers from RRC _ INACTIVE and provides an NG-RAN level ID, i.e., a Radio Network Temporary Identity (I-RNTI), assigned by the access Network device that was last served by the first terminal.

Step 2: and if the access network equipment to which the first terminal is to be connected can resolve the identity of the access network equipment which is served for the first terminal at the last time and is contained in the I-RNTI, the access network equipment to which the first terminal is to be connected requests the access network equipment which is served for the first terminal at the last time to obtain the context data of the first terminal.

And step 3: and finally providing the context data of the first terminal for the access network equipment served by the first terminal.

And 4, step 4: and the access network equipment to be connected of the first terminal completes the recovery of the RRC connection.

After the above step 1, when the access network device to which the first terminal is to be connected decides to reject the recovery of the RRC connection, the first terminal is continuously maintained in RRC _ INACTIVE.

Case two: the network side initiates switching from an RRC-INACTIVE state to an RRC connected state, and the method specifically comprises the following conditions:

1. for the first terminal, a RAN paging trigger event occurs on the network side.

2. The network side triggers the RAN paging, the paging range is the whole RAN.

3. And the network side uses the I-RNTI to page the first terminal.

To sum up, the embodiment of the present application provides a paging monitoring method, where when a first terminal meets a second condition, the first terminal sends third indication information to a second terminal, where the third indication information is used to indicate that the second terminal is not needed to replace the first terminal for paging monitoring; the first terminal listens for pages. Optionally, the second condition comprises that the first terminal cannot camp on the current serving cell of the second terminal. Alternatively, the second condition comprises the first terminal failing in the second terminal's current serving cell. Or, the second condition includes that the first terminal fails to take the TAU in the current serving cell of the second terminal for a preset number of times. Alternatively, the second condition includes the first terminal being in an RRC connected state. Or, the second condition includes that the time length of the first terminal in the RRC connected state reaches a preset time length. Alternatively, the second condition includes the first terminal being switched from the RRC-IDLE state or the RRC-INACTIVE state to the RRC-connected state. That is, the first terminal does not need the second terminal to perform paging monitoring instead of the first terminal under any condition, and on the contrary, if the second condition is satisfied, the first terminal can perform paging monitoring by itself, thereby improving the flexibility of paging monitoring.
