Description

Method and device for transmitting heartbeat packet of instant messaging service in LTE system

technical field

The present invention relates to a Long Term Evolution (LTE, Long Term Evolution) system, in particular to a method and device for transmitting heartbeat packets of an instant messaging service in the LTE system.

Background technique

With the continuous improvement of the capabilities of intelligent terminals and the development of mobile Internet services, instant messaging (IM) services have become a very important type of service. Different from traditional Internet applications, IM service is a kind of service with particularity to the access network strategy. Since the interaction between IM services requires the direct participation of users, the frequency of interaction is not high and has certain randomness. At the same time, the IM service application has the characteristics of being idle for a long time. In order to ensure the real-time nature of user messages, the IM service application will periodically send heartbeat messages to the IM service server in the Internet to keep the IM application online. state. Generally, the sending of the heartbeat message will trigger the RRC connection establishment and RRC connection release processes of the Radio Resource Control (RRC) layer for many times, thereby generating a large amount of air interface signaling overhead. Correspondingly, when there are a large number of IM service users in the network, the air interface signaling resources of the access network will be greatly affected, thereby affecting the overall performance of the LTE-A radio access network, including the reduction of radio resource utilization, The PDCCH load increases, the paging channel load increases and the multi-user multi-service QoS guarantee is affected.

In order to overcome the above problems, the prior art mainly reduces the signaling overhead of the IM service by increasing the heartbeat message sending period of the IM service application and increasing the timeout period of the RRC connection release timer of the eNB. After the heartbeat message period is increased, the number of heartbeat messages sent per unit time is reduced, and the corresponding RRC signaling overhead is also reduced, which can achieve signaling optimization to a certain extent. The method of increasing the eNB RRC connection release timer is to try to reduce the frequency of RRC connection establishment and release by maintaining the RRC connection for a longer time. Some other technical solutions include a method of reducing downlink heartbeat packet PDCCH overhead and PRB resource overhead by grouping downlink multi-user heartbeat IP packets together for multicast transmission through a Multimedia Broadcast Multicast Service (e-MBMS) mechanism.

Then, according to the existing technical solution, if the heartbeat sending period of the IM service is increased, it is difficult to ensure the real-time performance of the IM service, which affects the user experience. At the same time, since the IM service belongs to the application layer service, it is difficult to guarantee the feasibility and the performance during the execution process. consistency. The method of using a large RRC connection release timer cannot solve the extra signaling overhead caused by the heartbeat message unless the RRC is always online. At the same time, the increase of RRC connection time will make more users in the RRC connection state, increase the complexity of eNB processing, reduce air interface radio resource utilization (PUCCH resources, etc.), and increase user power consumption. The method of using the e-MBMS mechanism for multicast transmission can only be applied to the sending of downlink heartbeat messages, and cannot be applied to end users that do not support e-MBMS services. , but also need to modify the core network architecture and equipment.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

In the embodiment of the present invention, the uplink heartbeat packet refers to the heartbeat packet sent by the UE side to the target server, and the downlink heartbeat packet refers to the heartbeat packet sent by the target server to the UE side.

Referring to FIG. 1, an embodiment of the present invention provides a method for transmitting heartbeat packets of an instant messaging service in an LTE system, which is applied to the network side and specifically includes the following steps:

Step 11, the network side receives the heartbeat packet notification information for the first instant messaging service sent by the first UE, the heartbeat packet notification information carries the heartbeat packet proxy function for indicating that the first instant messaging service is enabled, wherein the heartbeat packet proxy function is enabled. The first instant messaging service no longer periodically sends uplink heartbeat packets after the heartbeat packet proxy function is enabled.

Here, the heartbeat packet notification information can be sent by being carried in an RRC message, and the network side receives and saves the information. The heartbeat packet notification information may carry the source IP address, destination IP address, source port number and destination port number corresponding to the first instant messaging service. Specifically, the source IP address corresponding to the first instant messaging service may be the IP address of the first UE, and the destination IP address corresponding to the first instant messaging service may be the IP address of the target server corresponding to the first instant messaging service. Of course, the heartbeat packet notification information may also carry some other information, such as application type, heartbeat packet sending cycle and other information.

Step 12, the network side periodically sends a first uplink heartbeat packet on behalf of the first instant messaging service according to the heartbeat packet notification information.

Here, the network side periodically generates and sends a first uplink heartbeat packet according to the heartbeat packet notification information, wherein the source address, destination IP address, source port number and destination port number of the first uplink heartbeat packet are respectively The source IP address, destination IP address, source port number and destination port number corresponding to the first instant messaging service carried in the heartbeat packet notification information, thereby realizing that the first instant messaging service is represented by the network side and sent to the network side. The corresponding target server sends an uplink heartbeat packet to ensure the online status of the instant messaging service and the real-time communication. Specifically, the sending period of the first uplink heartbeat packet in step 12 may be determined by the heartbeat packet sending period carried in the heartbeat packet notification information, or a predetermined sending period may be directly configured on the network side.

In this embodiment of the present invention, an entity that performs the above steps may be determined according to a specific network structure. For example, a mobility management entity (MME) may execute the above step 11, and submit the received heartbeat packet notification information to a Serving Gateway of LTE, and the serving gateway extracts the heartbeat information, and records the heartbeat information contained in it. Source IP address, source port number, destination IP address and destination port number, or other information required for heartbeat packets. Then, the service gateway periodically sends a heartbeat packet to the target server corresponding to the first instant messaging service according to the stored heartbeat packet information, and the heartbeat packet contains at least the source IP address, the source port number, the destination IP address and the destination port number, and optionally Sex contains other information.

Through the above steps, the UE (instant messaging service) in the embodiment of the present invention no longer needs to periodically send heartbeat packets to the network side, which can reduce the number of RRC connection establishment/release times and reduce related signaling overhead.

After the above step 12, in the above transmission method of the embodiment of the present invention, the target server may also send a downlink heartbeat packet to the UE. At this time, the embodiment of the present invention may further include the following steps (please refer to FIG. 2 ):

Step 13, the network side receives the first downlink heartbeat packet of the first instant messaging service sent by the first target server.

Step 14, when the first instant messaging service corresponding to the first downlink heartbeat packet has the heartbeat packet proxy function enabled, determine the current connection state of the first UE corresponding to the first downlink heartbeat packet.

Here, after receiving the first downlink heartbeat packet, the network side can judge whether the first instant messaging service is enabled according to the heartbeat packet notification information of all instant messaging services that have the heartbeat packet proxy function enabled in the above step 11. Heartbeat packet proxy function. For example, according to the destination address and destination port number of the first downlink heartbeat packet, it can be determined whether there is a certain heartbeat packet notification information that carries the same source IP address and source port number, and if so, it indicates that the first instant messaging service The heartbeat packet proxy function has been enabled.

Step 15, if the first UE is in a connected state, directly send the first downlink heartbeat packet to the first UE.

Here, when the first UE is in the connected state, it means that an RRC connection is currently established between the network side and the first UE, so the first downlink heartbeat packet can be directly sent to the first UE through the RRC connection.

Step 16: If the first UE is in an idle state, broadcast and send the first downlink heartbeat packet carried in a paging message or a preset system information block to the first UE.

Here, when the first UE is in an idle state, it means that no RRC connection is currently established between the network side and the first UE. To avoid re-establishing the RRC connection, the above-mentioned downlink heartbeat packet is sent by broadcast/multicast in this embodiment of the present invention. Specifically, broadcast transmission may be performed through a paging message or a preset system information block (SIB).

In order to improve the transmission of messages, in this embodiment of the present invention, multiple downlink heartbeat packets may be carried in one paging message/system information block and sent. In this way, in the above step 16, the paging message or the preset system information block may also carry other downlink heartbeat packets except the first downlink heartbeat packet, and the other downlink heartbeat packets are received by the network side. Downlink heartbeat packets of other instant messaging services that have the heartbeat packet proxy function turned on. In this way, a paging message or a preset system information block can be used to carry multiple downlink heartbeat packets, which can be broadcast and sent to multiple UEs at one time. Each UE branch extracts and processes its respective downlink heartbeat packets from the paging message or the preset system information block.

The above describes how the embodiment of the present invention implements the proxy sending of the heartbeat packet. In this embodiment of the present invention, the termination of the proxy sending of the upstream heartbeat packet may be triggered by the following conditions:

1) When the instant messaging service with the heartbeat packet proxy function enabled is terminated, the UE side or the server side (application layer) sends a heartbeat termination message, and the network side will terminate the proxy sending of uplink heartbeat packets after detecting this information.

2) The network side does not receive the downlink heartbeat packet fed back by the target server within a preset time period after the proxy sends the uplink heartbeat packet, and terminates the proxy sending of the uplink heartbeat packet.

3) When the UE is detached, the network side terminates the proxy sending of the heartbeat packet.

When terminating the proxy sending of the uplink heartbeat packets, the network side can also delete the saved notification information of the heartbeat packets.

The above describes how the network side processes the uplink/downlink heartbeat packets in the embodiment of the present invention, and the processing method on the UE side will be further described below.

Referring to FIG. 3 , the method for transmitting heartbeat packets of an instant messaging service in an LTE system provided by an embodiment of the present invention, when applied to the UE side, specifically includes the following steps:

Step 31, the first UE sends heartbeat packet notification information for the first instant messaging service, the heartbeat packet notification information carries the heartbeat packet notification information for notifying the network side that the first instant messaging service has turned on the heartbeat packet proxy function, and instructs the network side proxy The first UE sends an uplink heartbeat packet.

Here, the above heartbeat packet notification information can be sent according to different strategies:

For example, a list of instant messaging services that need to enable the heartbeat packet proxy function can be pre-configured on the UE, and the first instant messaging service is added to the list; when it is detected that the first instant messaging service in the list is activated, the above-mentioned instant messaging service is sent. Heartbeat packet notification information;

Alternatively, after the first instant messaging service is started, the communication frequency between the first instant messaging service and the network side can be monitored, and if the communication frequency is less than a preset threshold (such as the default sending period of the heartbeat packet), the heartbeat is turned on. Packet proxy function, and send the above heartbeat packet notification information.

Alternatively, the user can decide when to activate the proxy function, for example, the user can activate the heartbeat packet proxy function at any time after the instant messaging service is activated, thereby triggering the sending of the above-mentioned heartbeat packet notification information.

The above-mentioned heartbeat packet notification information carries the source IP address, destination IP address, source port number and destination port number corresponding to the first instant messaging service, so that the network side periodically generates and sends the first heartbeat packet notification information according to the heartbeat packet notification information. An uplink heartbeat packet, wherein the source address, destination IP address, source port number and destination port number of the first uplink heartbeat packet are respectively corresponding to the first instant messaging service carried in the heartbeat packet notification information Source IP address, destination IP address, source port number, and destination port number.

Step 32, the first UE stops sending the uplink heartbeat packet of the first instant messaging service.

After the above step 32, the first UE may also receive downlink data packets from the network side.

Specifically, when the first UE is in the connected state, it means that an RRC connection is currently established between the network side and the first UE, so the downlink heartbeat packet delivered by the network side can be directly received through the RRC connection.

When the first UE is in an idle state, it may receive a paging message or a preset system information block broadcast and sent by the network side, and extract the downlink heartbeat of the first instant messaging service from the paging message or the preset system information block The packet is then submitted to the PDCP sublayer through the interface between the RRC sublayer and the Packet Data Convergence Protocol (PDCP) sublayer, and then submitted to the TCP/IP protocol stack by the PDCP sublayer for processing.

Through the above steps, it is realized that the network side acts as a proxy for the UE to send the uplink heartbeat packet, and the UE does not need to periodically send the uplink heartbeat packet to the network side, thereby reducing the number of RRC connection establishment and release times, and greatly reducing the above-mentioned RRC connection establishment and release process. Signaling overhead, saving air interface resources, enabling other Internet services to obtain more physical resource blocks (PRBs) and control channel resources. Moreover, the embodiment of the present invention can also greatly reduce the CCE resource overhead of the PDCCH and the PRB overhead of the PDSCH of the downlink heartbeat IP packet of the instant messaging service, thereby effectively improving the utilization rate of radio resources. In addition, in the embodiment of the present invention, the heartbeat packets of multiple instant messaging services are bundled and transmitted through paging messages or newly defined SIBs, which can avoid the dependence of the downlink heartbeat packet multicast transmission on the e-MBMS core network, and at the same time does not need to perform the core network architecture.
