Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a data service switching method, apparatus, base station, and system.
Background
With the development of mobile internet technology and intelligent terminal technology, mobile terminals such as mobile phones and the like have developed from simple conversation tools to intelligent communication tools, and become a mobile personal information collection and processing platform, and more internet services, such as QQ, WeChat, microblog, OTT (over the top) services and the like, can be accessed through the mobile terminals.
In the existing process of performing service access through a mobile terminal, uplink Data of all mobile terminals are transmitted to a service Gateway (S-GW) in a core Network through a base station (eNB), and then are handed over to a Public Data Network (PDN) Gateway by the S-GW, and finally are sent to a service server, and downlink Data sent to the terminal by the service server also needs to be transmitted to a base station to which the mobile terminal belongs through the S-GW in the core Network, and then are sent to the mobile terminal by the base station, so that the existing Data processing method needs to shuttle between the core Network and a wireless access Network.
With the development of internet services, local resource sharing based on a "social circle" becomes an emerging mobile communication mode, and local data traffic accounts for more and more of the total traffic. Even so, according to the above data transmission method, even if two mobile terminals under the same base station communicate with each other, the data sent by the source terminal to the destination terminal is transmitted to the S-GW through the base station, then sent to the PDN gateway by the S-GW, and then accessed to the service server, and then sent to the base station through the service server, and then sent to the destination terminal by the base station. Therefore, in the data transmission mode, on one hand, routing roundabout exists, and data transmission delay is increased; on the other hand, the signaling load of the network elements of the core network is increased.
To solve the above problems, the prior art proposes Local IP Access (LIPA) and selective IP Traffic Offload (SIPTO) technologies. LIPA technology causes data to be shunted from a base station side by deploying a local gateway (L-GW) at the base station side, whereas SIPO technology allows gateway devices to be deployed in a distributed manner at a location close to a User to transfer certain types of traffic to a network node closer to a UE attachment access point, and selects a GW closer to a UE attachment point geographical/logical location when selecting a GW (including an S-GW and a P-GW (packet data gateway)) serving the UE (User Equipment), so as to alleviate a signaling load of a core network element. The local access technologies such as the LIPA and SIPTO technologies are adopted to relieve the signaling load of the network element of the core network to a certain extent, but if a user moves in the process of using the local service access technology to access the service, service access interruption may be caused, and the service experience of the user is influenced.

Detailed Description
In order to ensure service interruption caused when a cell is switched in a process of using a local access technology to perform service access by a UE, ensure continuity of service access and improve user service access experience, embodiments of the present invention provide a data service switching method, apparatus, base station and system.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
As shown in fig. 1, which is a schematic diagram of an implementation flow of a data service switching method provided in an embodiment of the present invention, the method includes the following steps:
and S11, receiving the measurement report reported by the UE.
The measurement report is measured in the process of carrying out service access by the UE by using a local access technology and reported to the base station.
S12, according to the received measurement report, judging whether the UE meets the cell switching condition, if yes, executing step S13, otherwise, returning to execute step S11.
S13, sending a service bearer establishment request to the core network device, so as to establish a service bearer for the currently ongoing service.
In specific implementation, the base station may send a service bearer request to an MME (mobility management entity) in the core network, so as to establish a service bearer for the currently ongoing service.
And S14, after the service bearer is established, switching the current service of the UE to the established service bearer for execution.
After the service currently performed by the UE is switched to the established service bearer and executed, the base station currently accessed by the UE (for convenience of distinguishing from the base station accessed by the UE after cell switching, in the embodiment of the present invention, the base station currently accessed by the UE is referred to as a source base station, and the base station accessed by the UE after cell switching is referred to as a target base station) sends a cell switching request to the target base station satisfying the cell switching condition according to the measurement report to perform cell switching, and the target base station performs a cell switching process with the source base station according to the cell switching request sent by the source base station to complete cell switching. After the cell switching is completed, the source base station notifies the target base station of the IP (internet protocol) address of the service server currently performing the service for the UE, and certainly, the source base station may also carry the IP address of the service server currently performing the service for the UE in the cell switching request.
After the UR is handed over to the target base station, the target base station may determine whether to establish the local routing connection according to the flow shown in fig. 2:
and S21, receiving a cell switching request sent by the source base station.
The cell switching request may carry an IP address of a service server where the UE is currently performing a service.
S22, after executing the cell switch according to the cell switch request, judging whether the IP address of the service server of the UE currently performing the service exists in the pre-stored local service server IP address list, if so, executing the step S23, otherwise, executing the step S25.
S23, according to the IP address of the service server of the UE currently performing the service, establishing a local routing connection with the corresponding service server.
And S24, switching the current service of the UE to the established local routing connection for execution, and ending the process.
And S25, keeping the current service data transmission route unchanged.
That is, in step S25, the service access is still performed using the service bearer established before the cell handover.
In specific implementation, the terminal may perform service access through an existing local access technology (LIPA technology or SIPTO technology). However, as the LIPA and SIPTO technologies perform service access, a new gateway device needs to be deployed in the network, and the newly added gateway device still belongs to a core network element in nature, so that after the LIPA technology and the SIPTO technology are adopted, the signaling load of the core network is still large, and in addition, a local gateway needs to be additionally deployed on the base station side in the two schemes, and hardware cost is also increased. Therefore, the embodiment of the present invention further provides a data routing method, and reference is first made to fig. 3, which is a schematic view of an application scenario of the data routing method according to the embodiment of the present invention. When a base station (eNB) receives a data routing request, if the current ongoing service is determined to be a local service according to the data routing request, the base station establishes local routing connection with a local service server in a local network and routes a received data Packet to the local routing server for processing, otherwise, the base station routes the received data Packet to an EPC (Evolved Packet core) for processing through a core network dedicated bearer established for the current service, and the EPC routes the data Packet to a corresponding service server in the Internet for processing according to the data Packet to be routed. For example, the local network in fig. 3 may be a campus network, and the user accesses the campus library in the campus by using the user terminal, and the local service server in the local network may be a campus library server.
In the following, in connection with the application scenario of fig. 3, a data routing method according to an exemplary embodiment of the present invention is described with reference to fig. 4. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.
As shown in fig. 4, which is a schematic diagram of an implementation flow of a data routing method provided in an embodiment of the present invention, the data routing method may include the following steps:
and S41, receiving the data routing request.
Wherein, the received data route request carries the data packet to be routed. When the user terminal accesses the service, the data packet sent to the service server needs to be forwarded through the base station.
S42, judging whether the current ongoing service is a local service according to the received data routing request, if so, executing a step S43, otherwise, executing a step S45;
and S43, establishing local routing connection with the local service server.
And S44, routing the received data packet to a local service server through the established local routing connection, and ending the process.
S45, establishing a core network special bearer with the EPC;
and S46, routing the received data packet to the corresponding service server through the established special bearer of the core network.
In specific implementation, the following two situations may occur when the base station receives the data routing request: one case is a data routing request sent for a data packet sent by the user terminal to the service server, and the other case is a data routing request sent for a data packet sent by the service server to the user terminal. If the data routing request is sent for a data packet sent by the user terminal to the service server, the data routing request usually reaches the base station first, so that under the condition, the base station can analyze the received data routing request and judge whether the current service of the user terminal is a local service, if so, the base station directly establishes local routing connection with the local service server without requesting to establish a special bearer to a core network to forward the received data packet; accordingly, if the UE moves to complete the cell handover under this condition, since the service bearer has not been previously established for the UE for performing the service data transmission, in step S13, a corresponding service bearer needs to be established for the UE for the currently ongoing service for performing the service data transmission.
In this case, even if the service server is a local service server, since the service server cannot determine whether the current service is a local service, the service server needs to send the data packet to the base station through the core network and send the data packet to the user terminal through the base station, that is, in this case, the base station already establishes a dedicated bearer for the core network when receiving the data packet. Subsequently, after receiving a data routing request sent for a data packet sent by the user terminal to the service server, if the base station determines that the current service is a local service, the base station establishes a local routing connection with the corresponding local service server, and then directly routes the data packet to the local service server through the established local routing connection. In order to save transmission resources, the base station may send a resource release request to an MME (Mobility Management Entity) to release an established dedicated bearer for the core network; or only releasing the user data bearer in the core network dedicated bearer and reserving the control data bearer. Accordingly, in this case, since the service bearer is already established for the service currently performed by the UE, in the specific implementation, the service bearer established for the UE may be activated in step S13, or if only the control data bearer exists, only the user data bearer is established, the control data bearer is activated, and the like.
In specific implementation, in order to implement the data routing method provided in the embodiment of the present invention, the base station may integrate address resolution and routing conversion functions, and based on this, in step S42, it may be determined whether the current ongoing service is a local service according to any one of the following manners:
in the first embodiment, the user terminal carries corresponding indication information in the sent data routing request.
In this embodiment, the UE (user equipment) may carry indication information indicating that the currently ongoing service is the local service in the sent data routing request, and thus, in step S42, it may be determined whether the currently ongoing service of the UE is the local service according to the indication information carried in the received data routing request. In a specific implementation, the base station may be indicated by one byte of information, for example, "1" indicates that the currently ongoing service is a local service, and "0" indicates that the currently ongoing service is not a local service. After receiving the data routing request, the base station determines that the UE is currently performing the service as the local service if it is determined that the indication information is "1", and may determine that the UE is currently performing the service as the local service if it is determined that the indication information is "0".
In specific implementation, if the base station determines that the current ongoing service of the UE is a local service, the base station establishes a local routing connection with the corresponding local service server. Specifically, the base station may send a connection establishment request to the local service server, and after receiving a response message returned by the local service server, determine that the local routing connection established with the local service server is successful.
Preferably, if the core network bearer is already established for the UE before the local routing connection is established, the currently ongoing service is transferred to the established local routing connection, that is, the data packet sent between the UE and the local service server is no longer carried through the established core network. In order to save the core network resources, the core network dedicated bearer established for the UE may also be released after the local routing connection is established, or part of the core network resources may be released, for example, only the user data bearer of the UE is released, and the control data bearer is reserved.
In specific implementation, if there are multiple local service servers deployed currently, before the base station establishes a connection with the local service servers, it needs to determine the local service server corresponding to the current service first. For example, the base station may identify the data packet to obtain the service identifier included therein, and the base station establishes a local routing connection with the corresponding local service server according to the obtained service identifier. Specifically, the base station may obtain the service identifier included in the data packet by using a deep packet inspection technology. Preferably, in a specific implementation, the base station may further pre-store a corresponding relationship between the service identifier and an IP (internet protocol) address of the corresponding local service server, so that after the service identifier is obtained, the base station may establish a local routing connection with the corresponding local service server according to the IP address of the local service server corresponding to the service identifier.
In the second embodiment, the base station determines whether the current ongoing service is a local service according to a URL (uniform resource locator) carried in the data routing request.
In this embodiment, when the user terminal initiates a service access request to the service server, a data routing request sent for a data packet sent by the user terminal to the service server carries a URL corresponding to the service server, the base station parses the URL to obtain an IP address corresponding to the URL, and determines whether the parsed IP address is in a local service server IP address list stored in advance, if so, it may be determined that a service currently performed by the UE is a local service, and if not, the base station may determine that the service currently performed by the UE is not a local service.
If the base station determines that the current service of the UE is a local service according to the analyzed IP address, in step S43, the base station may establish a local routing connection with the corresponding local service server according to the analyzed IP address, and route the data packet to be routed to the local service server through the established local routing connection.
In the data routing method provided by the embodiment of the invention, the base station judges whether the current service of the terminal is a local service, if the base station judges that the current service of the UE is the local service, the base station establishes local routing connection with the local service server, and directly routes the data packet to be routed to the local service server without routing through a core network, thereby reducing the signaling load of a network element of the core network. In the process of local service access of the UE, if the UE is subjected to cell switching due to movement, before cell switching is executed, corresponding service bearer is established for the currently-performed service of the UE and core network equipment for transmitting service data, and cell switching is started after the currently-performed service of the UE is switched to the established service bearer to be executed, so that a service access terminal caused by cell switching is avoided, the continuity of service access is ensured, and the service experience of a user is improved. Meanwhile, in the process of cell switching or after cell switching is completed, the IP address of the service server currently performing the service by the UE is notified to the target base station, and after cell switching is completed, the target base station establishes local routing connection for the UE according to whether the IP address of the service server currently performing the service by the UE exists in a pre-stored local service server IP address list or not, and switches the service data transmitted on the previously established service bearer to the established local routing connection for transmission so as to reduce the signaling load of the network element of the core network.
