Description

Method and device for adjusting PoC heartbeat packet sending interval

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for adjusting a PoC heartbeat packet transmission interval.

Background

PoC (Push to Talk over Cellular) refers to a half-duplex Voice service similar to trunking communication implemented by using a VoIP (Voice over IP) technology based on a mobile Cellular network packet domain bearer, and can support functions such as one-to-one session, one-to-many group session, state real-time presentation, group list management, and the like. It is characterized in that: the user applies for the Talk right in the conversation through a special PTT (Push To Talk) button, and after obtaining the Talk right and obtaining a corresponding prompt, the user can start talking. In a half-duplex conversation, when one party speaks, other members can only listen and cannot speak.

In order to maintain a long connection between the PoC terminal and the PoC cloud service platform, the PoC terminal is required to periodically send a heartbeat packet to the PoC cloud service platform when there is no PoC data traffic. The turn-on delay of the PPT service is the most important technical indicator of PoC, and generally has strict requirements. In a mobile packet network, due to the Discontinuous Reception (DRX) mechanism, the turn-on delay is greatly associated with the transmission interval of heartbeat packets. At present, a PoC terminal sends a heartbeat packet to a cloud service platform by adopting a fixed period, if the sending interval of the heartbeat packet is too long, the PoC terminal may be considered as having no service route by a mobile network or a firewall so as to release a link and cause that long connection cannot be maintained, or PPT service connection delay exceeds standard when the PoC terminal is in an Idle state DRX at the mobile network side; if the transmission interval of the heartbeat packet is too short, the PoC terminal needs to frequently transmit the heartbeat packet, thereby increasing network load and terminal power consumption and further shortening standby time. Therefore, how to dynamically adjust the sending interval of the heartbeat packet of the PoC terminal to achieve the balance between the PoC PPT call success rate, the connection delay, the network load and the terminal power consumption needs to be solved urgently.

Detailed Description

First, partial terms related to the embodiments of the present application are explained so as to be easily understood by those skilled in the art.

1. PoC service: the PoC service is a trunking communication system based on a mobile communication network by utilizing VoIP technology, can realize flexible talkback in a wider range covered by the mobile communication network, and is extension and substitution of the functions of the traditional trunking communication products. The PoC service is based on IP technology, which is carried over a data network of the GPRS/WCDMA/LTE/5G NR Packet switched Domain (PS). With the help of IP technology, the PoC service can be implemented to be continuously on-line, and network resources are occupied only when a user speaks, rather than being occupied all the time during the entire session connection, thereby enabling more efficient use of mobile communication network resources than circuit-switched voice services.

The PoC service appears in the form of an application layer wireless Access Point (AP) at a mobile terminal, for example, after a client logs in a mobile phone talkback function, a function of one-to-one or one-to-many conversation can be realized by pressing a key on the mobile phone in a manner of adding a contact or creating a group after the client logs in the mobile phone talkback function. However, PoC has high requirements for the turn-on delay of the PPT service and the delay of voice data, and the time delay from the initiation of a calling party to the turn-on of a called party needs to be controlled within a preset time. That is, the calling PoC terminal PPT key is pressed, the PoC AP initiates an intercom service to the PoC server through the PS domain of the public wireless network to transmit voice data, the PoC server calls the called terminal through the PS domain of the public wireless network, and a delay of turning on and forwarding the voice data needs to be controlled within a preset time.

2. Heartbeat package: in order to realize continuous online of the PoC service, as with most mobile network applications, the application of the PoC service also uses a heartbeat packet to realize long connection with the PoC cloud server after being powered on and online, and the functions of the heartbeat packet mainly include the following two aspects: on one hand, when the server and the client do not have effective business data to come and go within a certain time, the heartbeat packet is sent to the opposite terminal, so that the normal connection between the client and the server can be kept. On the other hand, a connection does not have normal data and heartbeat packets for a long time, the connection is considered to be absent, and in order to save server connection resources, the connection resources can be recycled by closing the socket, so that whether a link is normal or not can be detected by sending a heartbeat packet to an opposite end through any end.

Referring to fig. 1, fig. 1 is a schematic view of a scene according to an embodiment of the present disclosure. As shown in fig. 1, the scenario includes a PoC terminal 110, a cloud server 120, and a gateway 130. The network 130 may be a Serving Gateway (S-GW) or a packet data network Gateway (PDN-GW). Wherein the PoC terminals 110 include a calling PoC terminal 111 and a called PoC terminal 112. Calling PoC terminal 111 sends the PoC service to gateway 130 over the wireless network for forwarding. The gateway 130 then sends it to the cloud server 120 over the IP bearer network. The cloud server 120 receives the PoC service and then sends the PoC service to the called PoC terminal 112 through the gateway 130, either directly or in a similar manner.

The main quality index of the PoC service is the time delay from the PPT key of the calling PoC to the call PoC speech connection process after being pressed. In an actual wireless network, the PoC speech connection delay mainly comes from the processing delay of the application layer of the PoC calling party, the air interface delay of the public wireless network initiated by the calling party, the processing delay of the base station and the switch of the public wireless network, the processing delay of the PoC server, the paging PoC called delay of the base station of the public wireless network, the receiving delay of the air interface data of the PoC called party, and the processing delay of the application layer of the PoC called party. The calling initiated wireless public network air interface time delay and PoC called air interface data receiving time delay are respectively determined by the signal quality of the current calling and called wireless networks, the paging time delay of the PoC called is mainly related to the current network state of the called terminal, and other time delays are caused by non-wireless environment and are relatively fixed in a certain time. When the network works normally and the server load is moderate, the influence of the paging delay of the PoC called party on the whole PoC connection delay is the largest.

In 3GPP series (2G/3G/4G/5G) wireless networks, the PoC called paging delay is related to the current state of the PoC terminal in the wireless network (Radio Resource Control (RRC) Connected state or RRC Idle (Idle) state). In the RRC Connected state, a Physical Downlink Shared Channel (PDSCH) specified by a Physical Downlink Control Channel (PDCCH) of a Cell-Radio Network Temporary Identifier (C-RNTI) dedicated to the PoC terminal directly receives called information and a Scheduling Request (SR) transmitted by a Physical Uplink Control Channel (PUCCH), although a Connected DRX (Connected DRX, CDRX) period (set within 320ms, for example) does not cause a large connection delay due to the Connected DRX, and the terminal is continuously synchronized with the Radio Network in the frequency domain, and the influence of reception and transmission delays caused by the Network quality is relatively small. However, the PDCCH needs to be continuously detected in the RRC connected state, and CDRX sleep time is short, so that power consumption is large and standby time is short. If there is no uplink transmission or downlink reception service in the RRC connected state for a period of time (generally, the network side is set to 10s to 15s), then the RRC connection is released and the Idle state is entered. In the Idle state, the PoC terminal monitors a PDSCH channel indicated by a PDCCH channel of Paging RNTI (Paging RNTI, P-RNTI) in a DRX Paging cycle, finds that it is paged and then initiates a random access procedure to enter an RRC connection state, and then receives called data. Compared with the RRC connected state, the increased delay in the Idle state mainly comes from the DRX paging cycle and the random access + RRC connection establishment procedure, for example, if the DRX paging cycle of the network is configured to 320ms to 1.28S, if the DRX cycle of the wireless network where the PoC terminal is located is configured to 1.28S, the PoC terminal receives paging data every 1.28S, if the PoC connection delay is set to 500ms, it is obviously impossible to ensure that the PoC connection delay is within 500ms, and meanwhile, since the time-frequency domain synchronization to the network in the Idle state is not continuous and the data reception needs to be performed through random access to enter the RRC connected state, the connection failure is easier in the Idle state than in the RRC connected state, that is, the requirement on the quality of the wireless signal is higher. In the Idle state, the paging message is received by taking DRX as a cycle, and the terminal is always in a dormant state, so that the power consumption is low and the standby time is long.

In order to solve the above problems, the present application provides a method for adjusting a sending interval of a PoC heartbeat packet, where a PoC cloud server dynamically adjusts a sending time interval of a current PoC terminal heartbeat packet according to a current electric quantity state and/or a wireless network state condition reported by a PoC terminal in the heartbeat packet, and indicates a latest heartbeat packet sending interval in a response message of the heartbeat packet, so as to achieve a balance among a PoC PPT call success rate, a connection delay, a network load, and a terminal power consumption.

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting a PoC heartbeat packet sending interval according to an embodiment of the present application, and the method is applied to the scenario shown in fig. 1. As shown in fig. 2, the method includes the following steps.

S210, the PoC terminal sends a heartbeat packet to a cloud server, wherein the heartbeat packet comprises first information, and the first information is used for indicating the current electric quantity state and/or the wireless network state of the PoC terminal.

In the embodiment of the application, when the PoC terminal is powered on or the PoC terminal starts the PPT function, the PoC terminal may establish a long connection with the PoC cloud server, and the cloud server configures an initial heartbeat packet transmission interval of the PoC terminal. When the PoC terminal and the cloud server do not have valid service data to and from within a certain time, in order to avoid the cloud server from disconnecting the long connection with the PoC terminal, the PoC terminal may periodically send heartbeat packets to the cloud server according to an initial heartbeat packet sending interval (i.e., a current heartbeat packet sending interval).

The receiving and sending time delay of the air interface data is mainly determined by the signal quality of the current calling and called wireless networks, and the paging time delay of the PoC called is mainly related to the current network state of the called terminal. In order to achieve the balance among the call success rate, the connection delay, the network load and the terminal power consumption of the PoC PPT, when the PoC terminal sends a heartbeat packet, the current wireless network state and the current electric quantity state of the PoC terminal can be reported in the heartbeat packet, so that the cloud server can dynamically adjust the current heartbeat packet sending interval according to the current wireless network state and the current electric quantity state.

Optionally, the first information includes at least one of: discontinuous Reception (DRX) cycle, RRC connection hold time without service, radio signal quality and battery power.

The PoC terminal may obtain a Discontinuous Reception (DRX) cycle T _ DRX (paging cycle) by receiving a system message of a current serving cell (e.g., a base station), where the system message of the current serving cell may include the DRX cycle, and obtain an RRC connection retention time T _ RRC in the absence of service by counting a time from an RRC connection state to a disconnection state to an idle state when the current serving cell has no service to the PoC terminal, obtain the wireless signal quality SignalQuan by detecting the signal quality of the current serving cell, and obtain the Battery power Level by detecting a power indication of the PoC terminal. The wireless Signal Quality signalquery can be measured by Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), or Received Signal Strength Indicator (RSSI).

In this embodiment, the PoC terminal may selectively report the first information to the PoC cloud server in the form of a message in a heartbeat packet. The message format of the first information Info reported by the heartbeat packet can be seen in table 1.

TABLE 1

Info	T_DRX	T_RRC	SignalQuan	Battery＿Level
					4bit	2bit	2bit	2bit	2bit

Whether the four fields of T _ DRX, T _ RRC, SignalQuan, and Battery _ Level are valid or not is respectively indicated by the 4Bit of the first information Info, for example, a value of 1 indicates valid, and a value of 0 indicates invalid. The value or value range of the four fields of T _ DRX, T _ RRC, SignalQuan and Battery _ Level is expressed by 2 bits respectively.

Illustratively, the PoC terminal may classify DRX cycles, each class corresponding to a different DRX cycle period, and the DRX cycle class of the PoC terminal may be indicated by 2 bits of a T _ DRX field in a heartbeat packet. Similarly, the PoC terminal can classify the RRC connection retention time, the radio signal quality, and the battery power in the absence of service, respectively, each class corresponds to a different value range, and the class can be indicated by the value of the bit occupied by the corresponding field in the heartbeat packet.

For example, the PoC terminal currently resides in an LTE cell, and it can be known through receiving an SIB system message of the current cell that a DRX cycle configuration is in four levels of T _ DRX ═ 0,1,2, and 4, and DRX cycle periods respectively corresponding to the four levels are 0 to 320ms, 320 to 640ms, 640ms to 1.28s, and >1.28s, where a T _ DRX value of 00 denotes that the DRX cycle is at a level of 0, a T _ DRX value of 01 denotes that the DRX cycle is at a level of 1, a T _ DRX value of 10 denotes that the DRX cycle is at a level of 2, and a T _ DRX value of 11 denotes that the DRX cycle is at a level of 4. The method comprises the steps of obtaining the RRC connection holding time T _ RRC of the current service cell in the absence of service through actual test estimation, and dividing the RRC connection holding time T _ RRC into four levels of 0,1,2 and 4, wherein the corresponding time lengths are 0-5 s,5 s-15 s,15 s-25 s and >25s (the general network is set to be about 20 s), wherein the T _ RRC value of 00 represents that the RRC connection holding time is in the 0 level in the absence of service, the T _ RRC value of 01 represents that the RRC connection holding time is in the 1 level in the absence of service, the T _ RRC value of 10 represents that the RRC connection holding time is in the 2 level in the absence of service, and the T _ RRC value of 11 represents that the RRC connection holding time is in the 4 level in the absence of service. The current wireless signal quality SignalQuan can be obtained through measurement and is divided into four levels of 1,2, 3 and 4, the larger the level is, the larger the value is, the better the wireless signal quality is, wherein the SignalQuan value of 00 means that the wireless signal quality is in 1 level, the SignalQuan value of 01 means that the wireless signal quality is in 2 level, the SignalQuan value of 10 means that the wireless signal quality is in 3 level, and the SignalQuan value of 11 means that the wireless signal quality is in 4 level. The Battery capacity of the current PoC terminal, Battery _ Level, is divided into four levels, i.e., 0,1,2, and 3, which correspond to the Battery capacities of 0-15%, 15-30%, 30-60%, and 60-100%, respectively, where a value of Battery _ Level 00 indicates that the Battery capacity is at the 0 Level, a value of Battery _ Level 01 indicates that the Battery capacity is at the 1 Level, a value of Battery _ Level 10 indicates that the Battery capacity is at the 2 Level, and a value of Battery _ Level 11 indicates that the Battery capacity is at the 3 Level.

It should be noted that the bits occupied by the four fields of T _ DRX, T _ RRC, SignalQuan, and Battery _ Level may be determined according to the number or value of each divided Level, for example, if T _ DRX is divided into 6 levels, 3 bits may be used to represent the Level of T _ DRX. Therefore, the values or value ranges of the four fields of T _ DRX, T _ RRC, SignalQuan, and Battery _ Level can also be represented by 3Bit, 4Bit, 5Bit, etc. The examples of the present application are not intended to be limiting.

S220, the cloud server receives the heartbeat packet from the PoC terminal and determines a target sending interval according to the first information.

In the embodiment of the application, the cloud server analyzes first information reported by the PoC terminal in the heartbeat packet, and then comprehensively selects the heartbeat packet sending interval according to the first information, the PoC call configuration information and the self condition. As shown in fig. 3, when the PoC terminal and the cloud server do not have valid traffic data to and from within a certain time, the PoC terminal collects the non-traffic RRC connection holding time, DRX cycle, and radio signal quality from the wireless public network through the wireless communication module. And then the PoC terminal carries the collected information and/or the electric quantity information thereof in a heartbeat packet and sends the heartbeat packet to a cloud server through a wireless communication module, a network communication module of the cloud server analyzes the heartbeat packet after receiving the heartbeat packet, and transmits the analyzed information to a heartbeat packet dynamic setting module. And the heartbeat packet dynamic setting module determines a target sending interval according to the information, and then sends the target sending interval bearer and a heartbeat packet response message to the PoC terminal through the network communication module.

Optionally, the determining a target sending interval according to the first information includes: obtaining second information, the second information comprising at least one of: the method comprises the following steps of PoC connection delay requirement, PoC average calling delay, heartbeat packet average response delay and cloud server load; and determining the target sending interval according to the first information and the second information.

The PoC connection time delay requirement is a time delay requirement from the PPT key of the calling PoC terminal to the voice connection of the called PoC terminal, the PoC average calling time delay is the average time delay of paging the called PoC terminal in a preset time period counted by the cloud server, the heartbeat packet average response time delay is the average time delay of receiving the heartbeat packet response by the calling PoC terminal in the preset time period counted by the cloud server, and the cloud server load is the average thread number of the cloud server in an operation queue in a specific time interval and is used for measuring the current CPU workload of the cloud server.

Specifically, the first information and the second information both affect the selection of the target sending interval by the cloud server. For example, if the DRX cycle of the PoC terminal in the Idle state is greater than the PoC turn-on delay requirement, the PoC terminal must be in the RRC connected state for a long time in order to satisfy the turn-on delay requirement for the PPT service. If the overall quality of the current network of the PoC terminal is not good, in order to guarantee the quality of PoC communication, the PoC terminal needs to be in an RRC connection state for a long time, and the cloud server can reduce the interval duration of heartbeat packets, so that the PoC terminal sends heartbeat packets before RRC connection release every time, and the PoC terminal is ensured to be in the RRC connection state for a long time. If the power of the PoC terminal is insufficient or the cloud server is overloaded, the PoC terminal needs to be in an Idle state for a long time in order to reduce the power consumption and workload of the cloud server, and the cloud server can make the PoC terminal be in the Idle state for a long time by increasing the heartbeat packet interval duration, which is beneficial to prolonging the standby time of the PoC terminal and reducing the load of the cloud server although the PoC connection voice delay can be increased. Therefore, after the cloud server analyzes the first information reported by the PoC terminal in the heartbeat packet, the cloud server can comprehensively select a heartbeat packet sending period according to the PoC average calling time delay, the heartbeat packet average response time delay and the PoC connection time delay requirements of the PoC terminal in the latest time period and the load condition of the cloud server, and dynamically adjust the current PoC terminal heartbeat packet sending interval so as to achieve the balance among the PoC PPT calling success rate, the connection time delay, the network load and the terminal power consumption.

Optionally, the determining the target sending interval according to the first information and the second information includes: judging whether the battery electric quantity is less than or equal to a PoC low-power consumption battery threshold; if the battery power is less than or equal to the PoC low-power battery threshold, judging whether the PoC connection time delay requirement is greater than or equal to the DRX period; if the PoC connection time delay requirement is larger than or equal to the DRX period, judging whether the sending interval of the current heartbeat packet is smaller than or equal to the RRC connection holding time without service; and if the current heartbeat packet sending interval is less than or equal to the non-service RRC connection holding time or the PoC connection delay requirement is less than the DRX period, determining the target sending interval according to the cloud server load and the battery power.

After the cloud server receives the heartbeat packet and analyzes the first information, if the first information comprises battery power, the cloud server firstly judges whether the battery power of the PoC terminal is less than or equal to a PoC low-power battery threshold in order to avoid the power shortage of the PoC terminal, and when the battery power of the PoC terminal is less than or equal to the PoC low-power battery threshold, the PoC terminal may be in an Idle state in order to reduce the power consumption of the PoC terminal. Therefore, when the first information includes the DRX cycle, the cloud server determines whether the DRX cycle in the Idle state causes the PoC connection delay to be exceeded, that is, whether the PoC connection delay requirement is greater than or equal to the DRX cycle in the Idle state, and if the PoC connection delay requirement is greater than or equal to the DRX cycle in the Idle state, the PoC terminal needs to maintain a connection state in the wireless public network in order to meet the connection delay requirement for the PPT service; the PoC connection delay requirement is less than the DRX period in the Idle state, and the PoC terminal can be in a connected state or an Idle state in the wireless public network. Further, when the PoC terminal is in a connected state, the PoC terminal needs to send a heartbeat packet before RRC connection release, so that when the first information includes RRC connection holding time without service, the cloud server determines whether a current heartbeat packet sending interval is less than or equal to RRC connection holding time without service, and if the current heartbeat packet sending interval is less than or equal to the RRC connection holding time without service, the cloud server may comprehensively select a target sending interval according to a current network state, a cloud server load, and a battery power of the PoC terminal.

Optionally, the method further includes: and if the current heartbeat packet sending interval is larger than the RRC connection holding time without the service, determining that the target sending interval is the maximum value of the heartbeat packet sending interval which is smaller than the RRC connection holding time without the service.

Specifically, if the current heartbeat packet transmission interval is greater than the non-service RRC connection holding time, it indicates that the PoC terminal may not be able to transmit the heartbeat packet before RRC connection release, so the cloud server needs to shorten the heartbeat packet transmission interval, specifically, the cloud server selects a maximum value of the heartbeat packet transmission interval that is less than the non-service RRC connection holding time as a target transmission interval, so that the PoC terminal can transmit the heartbeat packet before RRC connection release. For example, suppose four levels, i.e., a PoC on-Delay requirement Delay _ threshold is 500ms, and a PoC service heartbeat packet transmission interval T _ keep is 0,1,2, and 3, which correspond to 10s, 15s, 25s, and 50s, respectively. If the current heartbeat sending interval is of a grade 2 and the RRD release time is 15s, at this time, the current heartbeat packet sending interval is greater than the RRC connection holding time when no service exists, and the cloud server needs to shorten the heartbeat packet sending interval, so the cloud server can set the target sending interval to be of a grade 1.

Optionally, the method further includes: if the battery capacity of the PoC terminal is larger than the PoC low-power battery threshold, judging whether the PoC terminal supports a low-power mode; if the PoC terminal supports a low power consumption mode, determining that the target sending interval is the maximum heartbeat packet sending interval; otherwise, judging whether the PoC connection time delay requirement is larger than or equal to the DRX period.

In a specific implementation, if the battery power of the PoC terminal is greater than the PoC low-power battery threshold, it indicates that the battery power of the PoC terminal is sufficient. If the PoC terminal supports the low power consumption mode, that is, the PoC terminal allows the low power consumption mode to be used, the PoC terminal may be in an idle state, and in order to reduce power consumption of the PoC terminal and extend standby time, the cloud server may select a maximum heartbeat packet transmission interval as a target transmission interval. If the PoC terminal does not support the low power consumption mode, in order to ensure that the PoC connection delay can be satisfied, the cloud server needs to determine whether the current DRX cycle causes the PoC connection delay to exceed a standard. If the PoC connection time delay requirement is larger than or equal to the DRX period, the PoC terminal needs to keep a connection state in the wireless public network; if the PoC connection delay requirement is less than the DRX period, the PoC terminal can be in a connection state or an idle state in the wireless public network. For example, assume that the PoC on-Delay requirement Delay _ threshold is 500ms, the PoC low-power Battery threshold Battery _ threshold is 0-15%, the Battery level of the PoC terminal is not 70%, and the PoC service heartbeat packet transmission interval T _ keep is 0,1,2, and 3, which correspond to 10s, 15s, 25s, and 50s, respectively, the current heartbeat transmission interval is 2, and if the PoC terminal supports the low-power mode, the cloud server sets the target transmission interval to 3 levels.

Optionally, the method further includes: judging whether third information meets a first condition, wherein the third information comprises at least one of the following items: the PoC average calling time delay, the heartbeat packet average response time delay and the wireless signal quality; if the third information meets the first condition, determining that the target sending interval is larger than the current heartbeat packet sending interval, otherwise, determining that the target sending interval is smaller than or equal to the current heartbeat packet sending interval.

Wherein the first condition is: the PoC average calling time delay is less than or equal to an average calling time delay threshold, the heartbeat packet average response time delay is less than or equal to the current heartbeat packet sending interval, the wireless signal quality is greater than a wireless signal quality threshold, and the heartbeat packet average response time delay is less than or equal to a heartbeat packet average response time delay threshold.

Specifically, the network performance of the PoC terminal is also an important factor that affects the PoC call delay, so the cloud server may count the overall average performance of the network over a period of time, and adjust the heartbeat packet transmission interval according to the overall average performance of the network. Specifically, when the third information satisfies the first condition, it indicates that the overall network quality of the PoC terminal meets the requirement, and the cloud server may extend the heartbeat packet transmission interval to reduce PoC terminal power consumption and cloud server load. When the third information does not satisfy the first condition, it indicates that the overall network quality of the PoC terminal is poor, and in order to ensure the quality of PoC communication, the cloud server needs to shorten a heartbeat packet transmission interval, so that the cloud server can receive the heartbeat packet.

Optionally, the method further includes: judging whether the target sending interval is larger than or equal to the RRC connection holding time without the service; if the target sending interval is greater than or equal to the RRC connection holding time without the service, the target sending interval is held; and if the target sending interval is smaller than the RRC connection holding time without the service, determining that the target sending interval is smaller than the current heartbeat packet sending interval.

Further, after the cloud server extends the heartbeat packet transmission interval, in order to avoid that the target transmission interval is too long, so that the PoC terminal cannot transmit the heartbeat packet before the RRC connection is released, the cloud server may determine whether the target transmission interval is greater than or equal to the RRC connection holding time when there is no service; and if the target sending interval is greater than or equal to the RRC connection holding time without service, indicating that the target sending interval meets the requirement. If the target sending interval is smaller than the RRC connection holding time without the service, it indicates that the target sending interval makes the PoC terminal unable to send the heartbeat packet before the RRC connection is released, so the cloud server needs to reduce the target sending interval, so that the target sending interval is smaller than the RRC connection holding time without the service.

In the embodiment of the application, the cloud server dynamically adjusts the sending time interval of the current PoC terminal heartbeat packet according to the wireless network configuration condition (DRX period, RRC connection holding time without service) reported by the PoC terminal in the heartbeat packet, the wireless signal quality and the electric quantity information, meanwhile, according to the statistics of the time delay of the received PoC terminal heartbeat packet, the statistics of the connection time delay of the called PoC terminal PPT service, the current cloud server load and the time delay requirement of the current PoC terminal PPT service, so as to achieve the balance among the PoC PPT call success rate, the connection time delay, the network load and the terminal power consumption.

Specifically, as shown in fig. 4, fig. 4 is a schematic flowchart of determining a target transmission interval according to an embodiment of the present application.

As shown in fig. 4, the method specifically includes the following steps:

s401, the cloud server analyzes the heartbeat packet to obtain battery power, DRX period, RRC connection holding time in the absence of service and wireless signal quality;

s402, the cloud server judges whether the battery power is less than or equal to a PoC low-power battery threshold;

s403, when the battery power of the PoC terminal is larger than the PoC low-power battery threshold, the cloud server judges whether the PoC terminal supports the low-power mode;

s404, when the PoC terminal supports the low power consumption mode, the cloud server determines that the target sending interval is the maximum heartbeat packet sending interval;

s405, when the PoC terminal does not support the low power consumption mode or the battery power is less than or equal to the PoC low power consumption battery threshold, the cloud server judges whether the PoC connection time delay requirement is greater than or equal to the DRX period;

s406, when the PoC connection delay requirement is larger than or equal to a DRX period, the cloud server judges whether the sending interval of the current heartbeat packet is smaller than or equal to RRC connection holding time when no service exists;

s407, when the current heartbeat packet sending interval is larger than the RRC connection holding time without the service, the cloud server determines that the target sending interval is the maximum value of the heartbeat packet sending interval which is smaller than the RRC connection holding time without the service;

s408, when the sending interval of the current heartbeat packet is less than or equal to the RRC connection holding time when no service exists or the PoC connection time delay requirement is less than the DRX period, the cloud server judges whether the third information meets a first condition;

s409, when the third information meets the first condition, the cloud server determines that the target sending interval is larger than the current heartbeat packet sending interval;

and S410, when the third information does not meet the first condition, the cloud server determines that the target sending interval is smaller than or equal to the current heartbeat packet sending interval.

The specific implementation manners of S401 to S410 may refer to the above implementation manners, and are not described herein again.

S230, the cloud server sends a heartbeat packet response to the PoC terminal, wherein the heartbeat packet response comprises the target sending interval.

Specifically, after the cloud server synthetically selects the target sending interval, the cloud server may carry the target sending interval in a heartbeat packet response message to the PoC terminal, and send the updated heartbeat packet sending interval to the PoC terminal.

S240, the PoC terminal receives the heartbeat packet response from the cloud server and adjusts the sending time of the heartbeat packet according to the target sending interval.

After receiving the heartbeat packet response, the PoC terminal updates the heartbeat packet sending interval according to the target sending interval sent by the cloud server. Illustratively, after updating the heartbeat packet transmission interval, the PoC terminal continues to measure the wireless network state and/or the power state so as to enable the cloud server to dynamically adjust the heartbeat packet transmission period in real time when the next heartbeat packet is transmitted. Illustratively, the PoC terminal may also send a bearer and heartbeat packet, which periodically measures a wireless network status and/or a power status, to the cloud server.

The method comprises the steps that the PoC terminal sends a heartbeat packet to a cloud server, wherein the heartbeat packet comprises first information, and the first information is used for indicating the current electric quantity state and/or the wireless network state of the PoC terminal; the PoC terminal receives a heartbeat packet response from the cloud server, wherein the heartbeat packet response comprises a target sending interval, and the target sending interval is determined by the cloud server according to the first information; the PoC terminal adjusts the transmission time of the heartbeat packet according to the target transmission interval. The PoC terminal in the application can adjust the sending interval of the heartbeat packet of the PoC terminal through receiving the target sending interval determined by the cloud server according to the reported first information, thereby realizing the dynamic adjustment of the sending interval of the heartbeat packet of the PoC terminal, and achieving the balance among the PoC PPT calling success rate, the connection delay, the network load and the PoC terminal power consumption.
