Description

Group calling configuration, receiving method and device, and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a group call configuration method, a group call receiving method, a group call configuration device, a group call receiving device, and a computer-readable storage medium.

Background

Paging (Paging) is a commonly used notification method in wireless communication, and is used for notifying a called User Equipment (UE), or notifying system message update, or notifying an alarm such as earthquake or tsunami. The notified UE may be in an idle state, an inactive state, or a connected state.

Paging typically includes core network triggered Paging (CN Paging) and access network side triggered Paging (RAN Paging). The UE in idle state needs to monitor the CN Paging, and the UE in inactive state needs to monitor the CN Paging and the RAN Paging. When monitoring Paging, the UE needs to determine its Paging Occasion (PO) according to its own identifier (5G-S-TMSI) and some other parameters, such as Paging Discontinuous Reception (DRX) cycle, and the specific way of determining PO may refer to standard protocol TS38.304. Recently, new Radio (NR) technology is considering the introduction of Multicast service (Multicast), and a network may transmit data to a plurality of UEs through a common transmission resource. For the multicast service with high requirement on service quality, the UE receiving the service is required to be in a connected state, however, the multicast service does not necessarily have data transmission continuously, and when there is no data transmission, the network can switch the UE receiving the multicast service to an idle state or an Inactive state (Inactive); when data transmission exists, the network wakes up the UE through Group calling (Group Paging), so that the UE in an idle state or an inactive state can enter a connected state to receive multicast data.

However, in the prior art, the UE always needs to wake up periodically to monitor Paging, and according to statistics, the proportion of the number of times that the UE is paged to the number of times of the whole Paging occasion is very low, that is, the UE does not have its own Paging message in most of the time, but the UE needs to wake up to monitor Paging, which causes the power consumption of the UE to increase.

Detailed Description

As described in the background art, in the prior art, the UE always needs to wake up periodically to monitor Paging, and according to statistics, the ratio of the number of times that the UE is paged to the number of times of the whole Paging occasion is very low, that is, the UE does not have its own Paging message in most of the time, but the UE needs to wake up to monitor Paging, which causes the power consumption of the UE to increase.

The inventor of the present application has studied and found that, in order to reduce the power consumption of the UE for listening to the Paging, considering introducing a Paging Early Indication (PEI), the UE may be configured to listen to the PEI before each PO that the UE needs to listen to. If the PEI indicates that the UE does not need to monitor the Paging message, the UE can maintain a Sleep (Sleep) state in the next PO without monitoring Paging; if PEI indicates that the UE needs to wake up to listen to Paging, the UE wakes up at the next PO to listen to Paging. Since the PEI further groups the UE to indicate whether the UE needs to wake up to monitor Paging, compared with Paging, PEI is simple in design and convenient for UE analysis, and therefore introduction of PEI can effectively reduce power consumption of the UE.

After the group call and the PEI are introduced simultaneously, when the UE receives the PEI and learns that the Paging does not need to be monitored, whether the UE needs to monitor the group call or whether the UE can continuously monitor the group call or the like needs to be clear, otherwise, the UE may not realize the function of saving electricity.

In the technical scheme of the invention, the network side equipment configures and sends the PEI configuration information to the user equipment, so that the user equipment can know whether the PEI is suitable for group calling. Under the condition that the PEI is suitable for the group call, the user equipment can know whether the group call is monitored or not by monitoring the PEI, and the power consumption of monitoring the PEI is smaller than that of monitoring the group call, so that the power consumption of the user equipment can be reduced on the whole.

It should be noted that, in the embodiment of the present invention, the PEI may be a paging advance indication, or may be any other practicable name, and the embodiment of the present invention is not limited to this.

The technical scheme of the invention can be applied to a 5G (5 Generation) communication system and can also be applied to various future new communication systems, such as 6G, 7G and the like.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a flowchart of a group call configuration method according to an embodiment of the present invention.

The group call configuration method of the embodiment of the invention can be used for network side equipment, namely, the network side equipment can execute each step of the method. The network side device may be a core network and a base station.

Specifically, the group call configuration method may include the following steps:

step S101: configuring paging advance indication configuration information, wherein the paging advance indication configuration information at least indicates whether a paging advance indication is suitable for group calling;

step S102: and sending the paging advance indication configuration information to at least one user equipment.

It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.

In the embodiment of the present invention, a network side configures a plurality of user equipments to receive a multicast service in a connected state, and when the user equipment receiving the multicast service is switched to an inactive state or an idle state, the network side equipment may configure the user equipments to receive a Group call (Group Paging), and the user equipments need to monitor a CN/RAN Paging at the same time, and at the same time, the network side configures a Paging Early Indication (PEI) for Paging of the plurality of user equipments.

In a specific application scenario, in the serving cell, UE1, UE2, …, UE10 receive Multicast service 1 (Multicast Session 1, MBS 1), UE11, …, UE22 receive Multicast service 2 (MBS 2). After a period of time, the network finds that there is no multicast data for a while, and turns each of the UEs into an idle state or an inactive state through Radio Resource Control (RRC) signaling, so that the UEs can save power. Before the state is switched into an idle state or an inactive state, the serving cell configures PEI for the UE and configures group calling. When configuring group calling, the network side needs to transmit to the UE the search space (search space) configuration for receiving the group calling, the period for monitoring the group calling, and the time for monitoring the group calling in the period.

It should be noted that the configuration parameters of the listening group call may be the same as or different from the configuration parameters of the existing Paging (CN Paging/RAN Paging). When monitoring the existing Paging, the UE detects a Downlink Control Information (DCI) scrambled by a Paging Radio Network Temporary Identity (P-RNTI). When the UE listens to the group call, the UE may detect DCI scrambled by other RNTI (i.e. RNTI for the group call is newly introduced), or the network may configure the group call DCI with a search space different from the existing paging (P-RNTI may be used), or the network may configure group call information for detecting a cell indication newly introduced in the existing paging (i.e. introducing a new cell into the existing paging message indicates a multicast service corresponding to the group call, such as MBS 1), and detect the group call.

In the embodiment of the invention, a network side can configure Paging Early Indication (PEI) configuration information for UE to at least indicate whether PEI is suitable for group calling, so that after the UE needing to monitor different Paging receives PEI, whether the group calling needs to be monitored is determined.

In one non-limiting embodiment, the network configures the UE with PEI configuration information indicating that PEI is suitable for a Group call (Group Paging). For example, for UE1, UE2, …, and UE10, the network may configure PEI to be applicable to a group call that the UE needs to monitor, so when detecting that the PEI indicates that Paging does not need to be monitored, UE1 to UE10 do not need to detect neither CN/RAN Paging nor group call.

In another non-limiting embodiment, the network may configure the UE with PEI configuration information indicating that PEI is not applicable to the group call.

In another non-limiting embodiment, the network side does not configure the UE with PEI configuration information, which also indicates that PEI is not applicable to the group call. For example, for UE11, …, UE22, the network may not configure PEI for the group call, and when these UEs receive the PEI indication that they do not need to monitor Paging, they do not need to detect CN/RAN Paging, but need to detect the group call.

In a non-limiting embodiment, the network side may configure the unified paging advance indication configuration information for the ue receiving the group call.

In one non-limiting embodiment, step S101 shown in fig. 1 may include the following steps: the network side can group a plurality of user equipment according to the types of the multicast services, and configure the paging advance indication configuration information for each group of user equipment respectively. That is, the network side may configure the paging early indication configuration information for the ue receiving the multicast service.

In this embodiment, different groups of user devices may configure the same or different PEI configuration information. The network side can configure the PEI configuration information for the user equipment according to the type of the multicast service. For example, for the UE receiving MBS1, that is, UE1, UE2, …, UE10, the PEI is configured for group calling; the UE receiving MBS2, i.e. UE11, …, UE22, configures PEI to be not suitable for group call.

Correspondingly, the PEI configuration information configured for each group of user equipment is respectively sent to each user equipment in the group. If the serving cell configures the same PEI configuration information for all the UEs needing to receive the group call in the cell, namely PEI is suitable for the group call or PEI is not suitable for the group call, the serving cell can configure PEI configuration information through system information.

It can be understood that the network side may also group UEs in any other implementable manner, and the embodiment of the present invention is not limited thereto.

In one non-limiting embodiment, step S101 shown in fig. 1 may include the following steps: configuring an applicable time window or applicable group calling times, and adding the PEI configuration information to indicate that the PEI is applicable to the group calling, wherein the applicable time window indicates a time range applicable to the PEI, and the applicable group calling times indicate monitoring times of the group calling applicable to the PEI.

The delay requirement of the multicast service is higher, the period of the group call may be shorter than the CN/RAN Paging period, that is, the group call is more frequent than the Paging. Specifically, referring to fig. 2, in the time range from time T1 to time T7, the number of paging is two, the monitoring occasions are T2 and T6, respectively, the number of group calling is three, and the monitoring occasions are T3, T4, and T7, respectively.

In this embodiment, when configuring the PEI configuration information, it may be considered that the PEI is only applied to the group call whose monitoring time is close to the PEI monitoring time, that is, only applied to the group call whose monitoring time is adjacent to the PEI monitoring time, and the group call whose monitoring time is far from the PEI monitoring time is not applicable to the PEI.

In specific implementation, the network side may configure a time window (i.e., an applicable time window). If the UE detects that the PEI indicates that monitoring paging is not needed, the paging of which the monitoring opportunity is located in the window comprises that the group calling UE does not need monitoring. For the group call whose monitoring opportunity is not in the applicable time window, the UE always needs to monitor.

For example, with reference to fig. 2, the PEI monitoring time T1 is taken as a starting point, and a group call with a monitoring opportunity T3 is included in a window with a duration of 5ms, so that when the PEI at the time T1 indicates that monitoring is not needed, the UE does not monitor the group call at the time T3, and similarly, the UE does not monitor paging at the time T2; for the group call with the monitoring opportunity of T4, since it is not in the window, even if the PEI at time T1 indicates that monitoring is not needed, the UE still needs to monitor the group call at time T4. By analogy, the PEI at monitoring time T5 is suitable for paging at monitoring opportunity T6 and group call at monitoring opportunity T7.

It should be noted that the length of the window may be predetermined, for example, may be predetermined by using a communication standard protocol; the starting time of the window may be a time corresponding to a page that needs to be monitored after the PEI, which is not limited in this embodiment of the present invention.

In another embodiment, the PEI is adapted to the group call that is the closest or a limited number of times to the PEI's monitoring time (thereafter), and for other subsequent group calls, the UE needs to monitor.

In one non-limiting embodiment, step S102 shown in fig. 1 may include the following steps: and sending the PEI configuration information to the at least one user equipment through RRC signaling or system information.

In one non-limiting embodiment, step S101 shown in fig. 1 may include the following steps: and configuring a reserved bit or a newly added bit of the PEI as the PEI configuration information to indicate that the PEI is suitable for the group call and whether the group call needs to be monitored.

In this embodiment, the PEI is a newly introduced DCI, where there is indication information of multiple bits in the PEI, and the network may configure some bits therein, for example, the last 1 bit is used to indicate whether the group call needs to be monitored. For the condition that an independent bit in the PEI is configured to indicate whether the group call needs to be monitored or not, when the UE detects the PEI, if the corresponding bit in the PEI indicates that the group call does not need to be monitored, the UE does not need to monitor the group call in the next opportunity.

Certainly, when the reserved bit or the newly added bit is configured on the network side, it means that the PEI is configured to be suitable for the group call. Otherwise, it means that the network side configures PEI not applicable to the group call.

In specific implementation, if the UE monitoring the group call does not configure the reserved bit or the newly added bit (PEI configuration information), that is, does not configure the independent bit in the PEI to indicate whether the group call needs to be monitored, the UE determines whether the CN/RAN Paging needs to be monitored only according to the PEI after receiving the PEI, and the UE always needs to monitor the group call.

Referring to fig. 3, fig. 3 shows a group call receiving method. The group call receiving method may be used at the user equipment side, that is, the user equipment may perform the steps of the method. The user equipment includes but is not limited to a mobile phone, a computer, a tablet computer and other terminal equipment.

Specifically, the group call receiving method may include the following steps:

step S301: receiving PEI configuration information, wherein the PEI configuration information at least indicates whether PEI is suitable for group calling;

step S302: and determining whether to monitor the group call according to the PEI configuration information.

In this embodiment, the UE is configured by the network side in a connected state to receive the multicast service, and is configured to receive the group call when the UE is shifted to an idle state or an inactive state, and meanwhile, the network side is configured with the PEI.

In a specific embodiment, step S302 shown in fig. 3 may include the following steps: if the PEI configuration information indicates that the PEI is suitable for the group call, determining whether to monitor the group call according to the content of the PEI; or monitoring the group call if the PEI configuration information indicates that the PEI is not suitable for the group call.

In specific implementation, the network side informs the UE of the PEI configuration information through RRC signaling, for example, a bit value of 1 indicates that the PEI is suitable for a group call, and a bit value of 0 indicates that the PEI is not suitable for the group call. One situation is that the UE learns that the PEI is suitable for group calling through the PEI configuration information, after the PEI is monitored, if the content indication of the PEI does not need to monitor, the UE continues sleeping at the group calling occasion without monitoring the group calling; if the content of the PEI indicates that monitoring is needed, the UE enters an awakening state at the group calling occasion to monitor the group calling, and the CN/RAN Paging also needs to be monitored at the moment. In another case, the UE learns that the PEI is not suitable for the group call through the PEI configuration information, and then the UE monitors the group call at the group call occasion; but the UE determines whether to listen to the CN/Paging page according to the content of the PEI.

In one particular embodiment. Step S302 shown in fig. 3 may include the following steps: acquiring an applicable time window; and determining whether to monitor the group call according to the content of the PEI for the group call of which the monitoring opportunity is positioned in the applicable time window. The time window may start at a listening time of the PEI or may start at a Paging (CN/RAN Paging) listening time.

Specifically, the UE first determines a time range covered by an applicable time window with the monitoring time of the PEI as a starting point or with the paging monitoring time as a starting point, and determines a group call whose monitoring opportunity is located in the time range. For the group calling, the UE can determine whether to monitor according to the content of the PEI. For the group call whose listening occasion is outside the time range, the UE always needs to listen.

It should be noted that the applicable time window may be configured for the UE by the network side, or may be agreed by a communication standard protocol.

In one embodiment, the PEI configuration information includes the number of applicable group calls. Step S302 shown in fig. 3 may include the following steps: and determining whether to monitor a plurality of group calls behind the PEI or not according to the content of the PEI.

Specifically, the UE first determines that a plurality of group calls at the monitoring opportunity after the PEI are group calls suitable for the PEI, and for the group calls, the UE may determine whether to monitor according to the content of the PEI. And for the group call which does not belong to the applicable group call times, the UE always needs to monitor.

In a specific embodiment, the PEI configuration information includes a reserved bit or a new bit of the PEI. Step S302 shown in fig. 3 may include the following steps: and determining whether to monitor the group call according to the bit value of the reserved bit or the newly added bit of the PEI.

Specifically, after monitoring the PEI, the UE determines the bit value of the reserved bit or the newly added bit of the PEI, and if the bit value indicates that the group calling does not need to be monitored, the UE does not need to monitor the group calling in the next group calling occasion. If the bit value indicates that the group call needs to be monitored, the UE needs to monitor the group call in the next group call occasion.

If the reserved bit or the newly added bit of the PEI does not configure the bit value, the PEI is not suitable for the group call. The UE determines whether to monitor CN/RAN paging based only on the content of the PEI.

The network can simultaneously configure a time window suitable for the PEI and a reserved bit or a newly added bit of the PEI for group calling.

Referring to fig. 4, an embodiment of the present invention further discloses a group call configuration device. The group call configuration means 40 may comprise:

a configuration module 401, configured to configure paging advance indication configuration information, where the paging advance indication configuration information at least indicates whether a paging advance indication is applicable to a group call;

In a specific implementation, the group call configuration device may correspond to a Chip having group call configuration in a network device, such as a System-On-a-Chip (SOC), a baseband Chip, or the like; or the network equipment comprises a chip module with a group calling configuration function; or to a chip module having a chip with a data processing function, or to a network device.

In the embodiment of the invention, the network side equipment configures and sends the PEI configuration information to the user equipment, so that the user equipment can know whether the PEI is suitable for group calling. Under the condition that the PEI is suitable for the group call, the user equipment can know whether the group call is monitored or not by monitoring the PEI, and the power consumption of monitoring the PEI is smaller than that of monitoring the group call, so that the power consumption of the user equipment can be reduced on the whole.
