Description
Technical Field
The invention relates to a Long Term Evolution (LTE) system, in particular to a method and a device for transmitting an instant messaging service heartbeat packet in the LTE system.
Background
With the continuous improvement of the capability of the intelligent terminal and the development of the mobile internet service, the Instant Messaging (IM) service has become a very important service. The IM service is different from the traditional Internet application and is a service with specificity to the access network strategy. Since the interaction between the IM services requires the direct participation of the user, the interaction frequency is not high and has a certain randomness. Meanwhile, the IM service application program has the characteristic of long-term idle online, and in order to ensure the real-time performance of user messages, the IM service application program and an IM service server in the Internet periodically send heartbeat messages to keep the online state of the IM application program. Generally, the sending of the heartbeat message triggers the RRC connection establishment and RRC connection release process of a Radio Resource Control (RRC) layer for multiple times, thereby generating a large amount of overhead of air interface signaling. Correspondingly, when a large number of IM service users exist in the network, the air interface signaling resources of the access network are greatly affected, and further the overall performance of the LTE-a radio access network is affected, including reduction of the utilization rate of radio resources, increase of PDCCH load, increase of paging channel load, and influence of multi-user multi-service QoS guarantee.
In order to overcome the above problems, the prior art mainly reduces the signaling overhead of the IM service by increasing the heartbeat message transmission period of the IM service application and increasing the timeout time of the RRC connection release timer of the eNB. After the heartbeat message period is increased, the number of the heartbeat messages sent in unit time is reduced, the corresponding RRC signaling overhead is reduced, and signaling optimization can be realized to a certain extent. The method of increasing the eNB RRC connection release timer attempts to reduce the frequency of RRC connection establishment and release by maintaining a longer RRC connection. Other technical solutions include a method for reducing PDCCH overhead and PRB resource overhead of downlink heartbeat packets by multicasting downlink multi-user heartbeat IP packets together through a multimedia broadcast multicast service (e-MBMS) mechanism.
Then, according to the existing technical scheme, if the heartbeat sending period of the IM service is increased, the real-time performance of the IM service is difficult to be ensured, which affects the user experience, and meanwhile, because the IM service belongs to the application layer service, the feasibility and consistency are difficult to be ensured in the execution process. 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 on-line. Meanwhile, the RRC connection time is increased, so that more users can be in an RRC connection state, the processing complexity of the eNB is increased, the utilization rate of air interface radio resources (PUCCH resources and the like) is reduced, the power consumption of the users is increased, and the like. The method for multicast transmission by using the E-MBMS mechanism can only be applied to the sending of downlink heartbeat messages and cannot be applied to terminal users which do not support the E-MBMS service, and meanwhile, in order to realize the transmission of downlink heartbeat IP packets through E-MBMS multicast, the core network architecture and equipment also need to be modified.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
In the embodiment of the invention, the uplink heartbeat packet refers to a heartbeat packet sent to the target server by the UE side, and the downlink heartbeat packet refers to a heartbeat packet sent to the UE side by the target server.
Referring to fig. 1, a method for transmitting an instant messaging service heartbeat packet in an LTE system, provided by the embodiment of the present invention, is applied to a network side, and specifically includes the following steps:
step 11, a network side receives heartbeat packet notification information, which is sent by a first UE and is directed to a first instant messaging service, where the heartbeat packet notification information carries information used for indicating that the first instant messaging service starts a heartbeat packet proxy function, and the first instant messaging service does not send an uplink heartbeat packet periodically after the heartbeat packet proxy function is started.
Here, the heartbeat packet notification information may be sent by being carried in an RRC message, and the network side receives and stores the information. The heartbeat packet notification information may carry a source IP address, a destination IP address, a source port number, and a destination port number corresponding to the first instant messaging service. Specifically, the source IP address corresponding to the first instant messaging service may be an IP address of the first UE, and the destination IP address corresponding to the first instant messaging service may be an 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 an application type, a heartbeat packet sending period, and other information.
And step 12, the network side periodically acts for the first instant messaging service to send a first uplink heartbeat packet 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 a source address, a destination IP address, a source port number and a destination port number of the first uplink heartbeat packet are respectively a source IP address, a destination IP address, a source port number and a destination port number corresponding to the first instant messaging service carried in the heartbeat packet notification information, so that the first instant messaging service is proxied by the network side, and the uplink heartbeat packet is sent to a corresponding target server, so as to ensure an instant messaging service online state and communication real-time performance. Specifically, the sending period of the first uplink heartbeat packet in step 12 may be determined by the sending period of the heartbeat packet carried by the heartbeat packet notification information, or a predetermined sending period may be directly configured by the network side.
In the embodiment of the present invention, the entity for executing the above steps may be determined according to a specific network structure. For example, there may be a Mobility Management Entity (MME) performing step 11, and submitting the received heartbeat packet notification information to a Serving Gateway (Serving Gateway) of LTE, where the Serving Gateway extracts the heartbeat information and records information carrying a source IP address, a source port number, a target IP address and a target port number, or information required by other heartbeat packets. Then, the service gateway sends a heartbeat packet to a target server corresponding to the first instant messaging service periodically according to the stored heartbeat packet information, wherein the heartbeat packet at least comprises a source IP address, a source port number, a target IP address and a target port number, and can also optionally comprise other information.
Through the steps, the UE (instant messaging service) in the embodiment of the invention does not need to periodically send the heartbeat packet to the network side any more, so that the times of establishing/releasing the RRC connection can be reduced, and the related signaling overhead is reduced.
After step 12, in the transmission method according to the embodiment of the present invention, the target server may further send a downlink heartbeat packet to the UE, and 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 a first downlink heartbeat packet of the first instant messaging service sent by the first target server.
Step 14, when the heartbeat packet agent function has been started by the first instant messaging service corresponding to the first downlink heartbeat packet, determining the current connection state of the first UE corresponding to the first downlink heartbeat packet.
Here, upon receiving the first downlink heartbeat packet, the network side may determine whether the first instant messaging service has started the heartbeat packet brokering function according to the heartbeat packet notification information of all instant messaging services having started the heartbeat packet brokering function received in step 11. For example, it may be determined whether a certain heartbeat packet notification message carries the same source IP address and source port number according to the destination address and destination port number of the first downlink heartbeat packet, and if so, it indicates that the first instant messaging service has started the heartbeat packet proxy function.
Step 15, if the first UE is in the connected state, directly sending the first downlink heartbeat packet to the first UE.
Here, when the first UE is in the connected state, it is described that an RRC connection is currently established between the network side and the first UE, so that the first downlink heartbeat packet may be directly sent to the first UE through the RRC connection.
Step 16, if the first UE is in an idle state, carrying the first downlink heartbeat packet in a paging message or a preset system information block, and broadcasting and sending the first downlink heartbeat packet to the first UE.
Here, when the first UE is in an idle state, it is described that no RRC connection is currently established between the network side and the first UE, and in order to avoid reestablishing the RRC connection, in this embodiment of the present invention, the downlink heartbeat packet is sent in a broadcast/multicast manner. Specifically, the broadcast transmission may be performed through a paging message or a preset System Information Block (SIB).
In order to improve the transmission message, the embodiment of the present invention may carry a plurality of downlink heartbeat packets in one paging message/system information block for transmission. In step 16, the paging message or the preset system information block may further carry other downlink heartbeat packets except the first downlink heartbeat packet, where the other downlink heartbeat packets are downlink heartbeat packets of other instant messaging services that have started a heartbeat packet proxying function and are received by the network side. Therefore, a plurality of downlink heartbeat packets can be carried by one paging message or a preset system information block and sent to a plurality of UE by one broadcast. And each UE branch extracts and processes the downlink heartbeat packet from the paging message or the preset system information block.
The above illustrates how embodiments of the present invention implement heartbeat packet proxy transmission. In the embodiment of the present invention, the termination of the proxy sending of the uplink heartbeat packet may be triggered by the following conditions:
1) when the instant communication service with the heartbeat packet proxy function started is terminated, the UE side or the server side (application layer) sends a heartbeat termination message, and the network side detects the message and then terminates the proxy sending of the uplink heartbeat packet.
2) And the network side stops the proxy sending of the uplink heartbeat packet if 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.
3) When the UE is detached (detach), the network side terminates the proxy sending of the heartbeat packet.
When the network side terminates the proxy sending of the uplink heartbeat packet, the stored heartbeat packet notification information can be deleted.
In the above, how to process the uplink/downlink heartbeat packets at the network side in the embodiments of the present invention is introduced, and the processing manner at the UE side will be further described below.
Referring to fig. 3, when the transmission method for the instant messaging service heartbeat packet in the LTE system provided by the embodiment of the present invention is applied to the UE side, the method specifically includes the following steps:
step 31, a first UE sends heartbeat packet notification information for a first instant messaging service, where the heartbeat packet notification information is carried to notify a network side that the first instant messaging service starts a heartbeat packet proxy function, and instructs the network side to proxy the first UE to send an uplink heartbeat packet.
Here, the heartbeat packet notification information may be transmitted according to different policies:
for example, an instant messaging service list that the heartbeat packet agent function needs to be started may be configured on the UE in advance, and the first instant messaging service is added to the list; when detecting that the first instant messaging service in the list is started, sending the heartbeat packet notification information;
or, after the first instant messaging service is started, monitoring a communication frequency between the first instant messaging service and the network side, and if the communication frequency is smaller than a preset threshold (for example, a default sending period of a heartbeat packet), starting a heartbeat packet proxy function and sending the heartbeat packet notification information.
Or, the user may decide when to start the proxy function, for example, the user may start the heartbeat packet proxy function at any time after the instant messaging service is started, so as to trigger the sending of the heartbeat packet notification information.
The heartbeat packet notification information carries a source IP address, a destination IP address, a source port number and a destination port number corresponding to the first instant messaging service, so that a network side periodically generates and sends a first uplink heartbeat packet according to the heartbeat packet notification information, wherein the source address, the destination IP address, the source port number and the destination port number of the first uplink heartbeat packet are respectively the source IP address, the destination IP address, the source port number and the destination port number corresponding to the first instant messaging service carried in the heartbeat packet notification information.
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 a downlink data packet from the network side.
Specifically, when the first UE is in the connected state, it indicates that an RRC connection is established between the current network side and the first UE, so that the downlink heartbeat packet sent by the network side can be directly received through the RRC connection.
When the first UE is in an idle state, the first UE may receive a paging message or a preset system information block broadcast and sent by a network side, extract a downlink heartbeat Packet of a first instant messaging service from the paging message or the preset system information block, submit the downlink heartbeat Packet to a Packet Data Convergence Protocol (PDCP) sublayer through an interface between the RRC sublayer and the PDCP sublayer, and submit the downlink heartbeat Packet to a TCP/IP Protocol stack for processing.
Through the steps, the uplink heartbeat packet is sent by the network side agent UE, and the UE does not need to periodically send the uplink heartbeat packet to the network side, so that the times of establishing and releasing the RRC connection can be reduced, the signaling overhead in the process of establishing and releasing the RRC connection is greatly reduced, the air interface resources are saved, and other Internet services can obtain more Physical Resource Blocks (PRBs) and control channel resources. In addition, the embodiment of the invention can also greatly reduce the CCE resource overhead of PDCCH and PRB overhead of PDSCH of the downlink heartbeat IP packet of the instant messaging service, and effectively improve the utilization rate of wireless resources. In addition, the embodiment of the invention can avoid the dependence of the multicast transmission of the downlink heartbeat packet on the e-MBMS core network by bundling and transmitting the heartbeat packets of a plurality of instant communication services through the paging message or the newly defined SIB, and does not need to modify the core network architecture.
Based on the transmission method provided by the above embodiment, the embodiment of the invention also provides a device for realizing the method.
