Detailed Description
Embodiments of the present application will be described below with reference to the accompanying drawings.
First, some terms in the embodiments of the present application are explained so as to be easily understood by those skilled in the art.
(1) A terminal, also referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user, including wired terminals and wireless terminals. The wireless terminal may be a handheld device having wireless connection capabilities, or other processing device connected to a wireless modem, a mobile terminal communicating with one or more core networks via a radio access network. For example, the wireless terminal may be a mobile phone, a computer, a tablet computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a wearable device, an electronic book reader (e-book reader), and the like. As another example, a wireless terminal may be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device. As another example, the wireless terminal may be a mobile station (mobile station), an access point (access point).
(2) The interaction in the present application refers to a process of transmitting information to each other by two interactive parties, where the transmitted information may be the same or different. For example, the base station 1 and the base station 2 may be both interacting parties, and the base station 1 may request information from the base station 2, and the base station 2 may provide the information requested by the base station 1 to the base station 1. Of course, the base station 1 and the base station 2 may request each other for information, and the requested information may be the same or different.
(3) "plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The "trunking paging message" in the embodiment of the present application is only an exemplary message naming method, and for example, other message names such as "trunking paging request" may also be used instead.
It should be noted that the communication mentioned in this application can be applied to Long Term Evolution (LTE) system, or other wireless communication systems using various radio access technologies, such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), single carrier-frequency division multiple access (SC-FDMA), etc., and can also be applied to subsequent evolution systems, such as fifth generation radio (5th generation, 5G, also called New Radio (NR)) system, or other evolution systems.
The DRX mechanism divides a Radio Resource Control (RRC _ CONNECTED) state of the UE into two different states, active and silent. When the UE is in an active state, the UE needs to continuously monitor and blindly detect a Physical Downlink Control Channel (PDCCH), and meanwhile, the UE may report information such as a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), and the like. When the UE is in the silent state, the UE does not need to monitor a PDCCH control channel and report information such as CQI/PMI/RI, and the like, thereby achieving the purpose of saving power of the user equipment. The basic mechanism of CONNECTED DRX is therefore to configure one DRX cycle (DRX cycle) for a UE in RRC _ CONNECTED state. The DRX cycle is composed of "On Duration" and "Opportunity for DRX (sleep period)": in the period of 'On Duration', the UE monitors and receives the PDCCH; during the "Opportunity for DRX", the UE does not receive the PDCCH to reduce power consumption (sleep period). As can be seen from fig. 1, in the time domain, time is divided into successive DRX cycles.
In the DRX activated state, the UE in the RRC _ CONNECTED state does not monitor a PDCCH scrambled by a Cell Radio Network Temporary Identifier (C-RNTI), PUCCH uplink power control information, PUSCH uplink power control information, and a semi-persistent scheduling Radio Network Temporary Identifier (SPS C-RNTI), and does not report information such as CQI/PMI/RI, or the like, otherwise, the PDCCH is not monitored.
The DRX mechanism in the LTE system involves the following timers: an activation Timer (onDurationTimer), a DRX inactivity Timer (DRX inactivity Timer), a Hybrid Automatic Repeat reQuest (HARQ), a round trip time Timer (HARQ RTT Timer), a DRX retransmission Timer (DRX-retransmission Timer), and a DRX short cycle Timer (DRX short cycle Timer). The timer configuration is realized by DRX-Config Information Element (IE) carried in RRC signaling MAC-MainConfig Information Element (IE).
The eNB configures DRX related parameters of the UE through the DRX-Config IE of the RRC connection establishment procedure, as shown in table 1:
Figure BDA0001744660480000091
Figure BDA0001744660480000101
TABLE 1
The choice of DRX cycle involves a balance between battery savings and latency. The DRX long period is beneficial to prolong the battery life of the UE, for example, web browsing, and when the user is reading a downloaded web page, resources are wasted if the UE continues to receive downlink data. A shorter DRX cycle will facilitate faster response when there is a new data transmission; thus, to meet the above requirements, each UE may configure two DRX cycles: short DRX-Cycle and long DRX-Cycle.
The DRX Start Offset specifies the starting subframe of the DRX Cycle, and the Long DRX Cycle specifies how many subframes a Long DRX Cycle occupies, both of which are determined by the Long DRX Cycle Start Offset field. The onDurationTimer specifies the number of consecutive subframes (i.e., the number of subframes for which the active period lasts) that need to monitor the PDCCH from the start subframe of the DRX cycle.
How to control the UE in RRC _ CONNECTED to enter DRX mode is described as follows:
the UE side: the UE enters a DRX state based on the timeout of the timer;
the eNB side: the eNB informs the UE to enter the DRX state through a DRX Command MAC control element.
In the standard design, a Trunking Control Channel is monitored by Trunking Paging triggering, after a UE detects a scrambled Physical Downlink Control Channel (PDCCH), receives a Trunking Paging message (trunk Paging) or a subsequent Group Call configuration message (Group Call configuration) on a PDSCH indicated by the PDCCH, if the UE receives a Group Call service, the UE starts monitoring the PDCCH and receives Group signaling and service data according to the Group resource configuration information in the Paging message. That is, after receiving the paging configuration of the cluster, the LTE system starts to monitor the PDCCH channel, and since the LTE system does not perform DRX in an idle state, monitoring of the control channel and the traffic channel shared by the cluster will exist all the time. This results in the inability to save UE energy and increase battery life in idle trunking terminal services. In addition, since multiple terminals of the trunking group service participate together, the broadband trunking standard employs a Hybrid Automatic Repeat Request (HARQ) feedback mechanism and a retransmission mechanism for the trunking service downlink, so that the current DRX service of the LTE connected terminal cannot be applied to the trunking service.
In the prior art, a trunking service is initiated when a terminal is in an idle state, and since the terminal in an LTE idle state does not have a DRX mechanism, power saving operation cannot be performed. When a terminal is in a connected state, the current DRX mechanism of LTE cannot be adopted in a trunking system because of the existence of a downlink HARQ feedback and retransmission mechanism. As a cluster system, a group service may be a typical service form in a cluster service, and also a main service form, including a voice group call, a visual group call, a homologous video group call, a video push, a video forward, a video pull-up, a return and the like, all belong to a group service. Therefore, the service of the terminal can also be the main service form, if an effective power-saving mode cannot be adopted well, the battery consumption of the terminal is very large, and the standby time of the terminal is influenced. Based on this, the present application provides a DRX implementation and configuration method and apparatus.
When initiating the trunking group service, because the called party in the group is in an idle state, the called party needs to be called by the paging message to access the trunking group service, and the called party in a connected state also monitors the Trunking Paging Channel (TPCH) to perform group configuration reception, a mode of uniformly carrying the DRX parameters of the trunking terminal in the trunking paging message is adopted. The terminal starts to activate DRX upon receiving the group paging message. And configuring different service durations according to different service types. And activating DRX to achieve the purpose of saving power.
Fig. 2 shows a schematic flowchart of a DRX implementation method provided in an embodiment of the present application, and as shown in fig. 2, the flow of the DRX implementation method provided in the embodiment of the present application may include:
s201: the trunking terminal receives a trunking paging message, which includes DRX configuration information of trunking services. The DRX configuration information of the cluster service includes: activating timer configuration information and DRX cycle configuration information; wherein the activation timer configuration information is used to indicate a duration of an activation period within one DRX cycle.
Optionally, the DRX cycle configuration information includes one or a combination of the following information:
DRX cycle start offset; the cycle length of the DRX long cycle; the cycle length of the DRX short cycle; DRX short cycle on indication information; the number of DRX short cycles.
Wherein, the DRX period starting offset is used for indicating the offset duration of starting the DRX long period and/or the DRX short period; the DRX short cycle on indication information is used to indicate whether to turn on the DRX short cycle.
S202: and the trunking terminal discontinuously receives the downlink transmission of the trunking service according to the DRX configuration information of the trunking service.
In a possible implementation manner, the terminal corrects the DRX configuration information of the trunking service according to the DRX configuration information of the LTE service, and the corrected DRX configuration information of the trunking service is applicable to the trunking service and the LTE service; and the trunking terminal performs discontinuous reception on the downlink transmission of the trunking service according to the corrected DRX configuration information of the trunking service.
In a possible implementation manner, the trunking terminal receives DRX configuration information of an LTE service, and corrects the DRX configuration information of the LTE service of the terminal according to the DRX configuration information of the trunking service of the terminal, where the corrected DRX configuration information of the LTE service is applicable to the LTE service and the trunking service; and the cluster terminal performs discontinuous reception on the downlink transmission of the LTE service according to the corrected DRX configuration information of the LTE service.
In the above two implementation manners of the embodiments of the present application, the present application is applicable to the situation where both the trunking service and the common public network service exist, for example, one service of the terminal is an LTE data service, and the subsequent terminal has a trunking voice group call service, at this time, it is necessary to consider DRX configuration information given to the terminal before and DRX configuration information given to the trunking service, which need to be kept consistent, so that the addition of the subsequent service does not affect the previous service processing. There are several processing scenarios:
(1) when the LTE service has a high priority, the DRX configuration information of the trunking service may be modified, so that the trunking terminal performs discontinuous reception on downlink transmission of the trunking service according to the modified DRX configuration information of the trunking service.
(2) When the priority of the trunking service is high, the DRX configuration information of the LTE service of the terminal may be modified, so that the trunking terminal performs discontinuous reception on downlink transmission of the LTE service according to the modified DRX configuration information of the LTE service.
(3) When the priority of the LTE service is the same as that of the cluster service, the DRX configuration information of the LTE service and the cluster service can be kept unchanged.
(4) And when the priority of the LTE service is the same as that of the cluster service, taking a middle value between each DRX configuration information of the cluster service and each DRX configuration information of the LTE service of the terminal.
In the above (3) - (4), the DRX configuration information of the trunking service and the DRX configuration information of the LTE service are inconsistent, which is wasteful of resources and does not achieve the purpose of saving power well.
Optionally, if the trunking terminal is configured with DRX configuration information of an LTE service, when the trunking terminal is handed over from a source cell to a target cell, the DRX implementation method according to the embodiment of the present application further includes:
when the cluster terminal is switched from a source cell to a target cell, the DRX configuration of the LTE service of the source cell is closed, the DRX configuration information of the LTE service of the target cell is received, and discontinuous reception is carried out on downlink transmission of the LTE service of the target cell according to the DRX configuration information of the LTE service of the target cell.
In a practical scenario applied to the foregoing embodiment, the trunking service does not have a feedback acknowledgement and retransmission mechanism for data transmission, and in view of this, only the activation timer and the service DRX cycle are set for DRX setting of a trunking terminal, and a specific duration configuration may be determined according to a service type of a trunking, or for simplification, a uniform DRX cycle is set for all services, and it is ensured that parameters are set by a base station and a terminal are consistent. The application is not limited thereto. The DRX specific configuration is shown in table 2:
Figure BDA0001744660480000141
TABLE 2
Wherein, the trigger condition of the activation timer (onDurationTimer) is that the UE currently uses short DRX cycle, or when the UE currently uses long DRX cycle.
The trigger condition of the DRX Short Cycle Timer is that when the DRX Short Cycle is configured, if the DRX-Inactivity Timer is overtime or receives DRX Command MAC control element, the DRX Short Cycle Timer is started or restarted and starts to use the DRX Short Cycle. When the DRX Short Cycle Timer times out, the DRX long Cycle is started to be used. When the DRX short Cycle timer is started, only the short DRX Cycle is used currently, but the DRX short Cycle is not necessarily started. The DRX short Cycle is started at the same time as the onDurationTimer, and similarly, the DRX long Cycle is started at the same time as the onDurationTimer. The number of the DRX Short cycles in the DRX Cycle configuration information in the DRX implementation method provided by the embodiment of the application can be known by a DRX Short Cycle Timer.
The minimum time the UE is active is specified by the onDurationTimer, while the maximum time is indefinite.
Fig. 3 is a flowchart illustrating a DRX configuration method according to another embodiment of the present application.
As shown in fig. 3, a flow of a DRX configuration method provided in an embodiment of the present application may include:
s301: the base station determines the trunking terminal receiving the trunking service.
