Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
fig. 1 is a flow diagram illustrating some embodiments of a method of selecting an access network according to the present disclosure.
as shown in fig. 1, the method of this embodiment includes: 110 to 130.
In step 110, the core network device senses the user's traffic.
The core network device may use a service detection mechanism to sense what service the user is using. The services of the user are, for example, voice services, wechat services, browser services, etc.
In step 120, the core network device determines the access network category of the user according to the service of the user and the reference information for selecting the access network.
wherein, the reference information includes but is not limited to: at least one of quality of service, priority of service, location of user, mobility state of user, and network load. The reference information is usually multiple items, and the core network device may select several items of reference information according to the service requirement and a preset policy to determine the access network category of the user.
Wherein the access network category may be, for example, a 4G (fourth generation) network, a 5G (5 th generation) network, etc., but is not limited to the illustrated example.
The present disclosure defines a first access network class and a second access network class to refer to two different access network classes, where the first and second are not used to denote size or timing, etc. The first access network class is set to have a larger bandwidth and faster transmission rate than the second access network class, which has better network coverage than the first access network class. The first access network class may be, for example, 5G and the second access network class may be, for example, 4G.
The method for determining the access network category of the user by the core network device includes:
and if the moving speed of the user is less than a preset value and the service quality of the service of the user for time delay and bandwidth is guaranteed, determining that the user belongs to the first access network category. For example, if a user is located in a hospital area and is substantially stationary and perceives that the user is using video surveillance, the core network setup may decide to place the user on a 5G network access. Thereby providing a larger bandwidth and a faster transmission rate for the video monitoring service of the user.
And if the moving speed of the user is greater than the preset value and the service quality of the service of the user for the time delay and the bandwidth is guaranteed, determining that the user belongs to the second access network category. For example, if a user is using video surveillance and is in a high-speed mobile state (e.g., the user leaves the hospital while driving), the core network setup may decide to place the user in 4G network access, thereby ensuring sufficient network coverage and avoiding video interruption due to frequent switching of wireless signals.
and if the user is located in the dense network user area and the user service belongs to the large-flow downloading service type, determining that the user belongs to the second access network category. For example, if a user is located in a campus area and the user uses a large volume download service such as P2P, the core network device may decide to place the user on a 4G network access. Thereby relieving the bearing pressure of the 5G network.
And if the service of the user has the requirement of ensuring the network coverage, determining that the user belongs to the second access network category. For example, if a user is using a voice service with a high requirement for network coverage, the core network device may decide to place the user in the 4G network for access, so as to fully utilize the good coverage performance of the 4G network and ensure the continuity of the user call.
if the user has a plurality of services at present, determining the access network category of the user according to the guarantee requirement of the service with the highest priority in the services on the service quality. For example, when a user is using voice and browser services and the priority of the voice service is the highest, the core network device may decide to place the user in the 4G network for access according to the guarantee requirement of the voice service on the service quality, so as to fully utilize the good coverage performance of the 4G network and guarantee the continuity of the user call.
And if the bandwidth required by the service of the user is less than the preset value and the guarantee requirement of the service quality without time delay exists, determining that the user belongs to the access network category of the current network of the user. Therefore, on the premise of meeting the service requirements of the users, network switching of the users is reduced. For example, if the bandwidth required by the service of the user is less than the preset value and has no guarantee requirement of delayed service quality, and the user is currently located in the network of the first access network category, the core network device may decide to leave the user in the network of the first access network category, and if the user is currently located in the network of the second access network category, the core network device may decide to leave the user in the network of the second access network category.
In step 130, the core network device sends the indication information of the access network category of the user to the wireless network device, so that the wireless network device resides the user in the access network of the corresponding category according to the indication information.
the wireless network device may be, for example, a serving base station of a user. The indication information of the access network category of the user comprises: identification information of the access network category of the user or indication information of the access network category of the network where the user is currently located is maintained. The wireless network equipment switches the user to the access network with the corresponding type of the identification information according to the identification information of the type of the access network of the user, or continuously resides in the network with the current type of the user according to the indication information of the type of the access network of the network where the user currently resides. If the access network category of the user is not changed, the core network device may not send the indication information to the wireless network device, so that the user continues to reside in the network of the current category.
In the embodiment, the core network equipment determines the access network type of the user according to the perceived service of the user and the reference information for selecting the access network, and indicates the type to the wireless network equipment, so that the wireless network equipment enables the user to reside in the access network of the corresponding type according to the indication, and the consideration factor for controlling the user to switch the network is enriched, thereby being capable of adapting to the complex network structure and various user requirements in the future network.
Fig. 2 is a flow chart illustrating methods of selecting an access network according to further embodiments of the present disclosure.
As shown in fig. 2, the method of this embodiment includes: step 210-230.
In step 210, the core network device determines the access network category of the user according to the perceived service of the user and the reference information for selecting the access network.
In step 220, the core network device sends an indication of the access network class of the user to the serving base station of the user.
In step 230, the serving base station camps the user on the access network of the corresponding category according to the indication information of the core network device. And if the user needs to switch the access network, the service base station switches the user to the target base station by referring to the traditional network switching process.
In the embodiment, the core network equipment determines the access network type of the user according to the perceived service of the user and the reference information for selecting the access network and indicates the type to the service base station, so that the service base station can reside the user in the access network of the corresponding type according to the indication, and the consideration factor for controlling the user to switch the network is enriched, thereby being capable of adapting to the complex network structure and various user requirements in the future network.
fig. 3 is a flow chart illustrating further embodiments of a method of selecting an access network according to the present disclosure.
it is assumed that the correspondence between the indication information of the access network class and the access network class between the core network device and the radio network device follows: the indication information ID of the access network type is 1, and the user uses the 4G network for access; the indication information ID of the access network type is 2, and the user uses a 5G network for access; and the indication information ID of the access network category is 3, and the user maintains the network access of the current category.
As shown in fig. 3, the method of this embodiment includes: 310-340.
Step 310 is the first business phase of the user, and includes steps 311-313.
in step 311, the user stands by in the 5G network and then initiates a wechat service.
In step 312, the core network device senses the WeChat service of the user, determines that the user uses a 5G network access to provide a network service with a larger bandwidth and a faster rate for the user in the case that the network load and the user state are normal, and sends the user identification and the indication information ID of the access network category of 2 to the wireless network device.
in step 313, the wireless network device learns that the user should use the 5G network for access according to the indication information ID of the access network category being 2, and ignores the indication information because the user is already in the 5G network and does not act.
step 320 is a second service phase of the user, comprising steps 321-323.
the user initiates voice traffic again at step 321.
in step 322, the core network device senses the voice service of the user, determines that the priority of the voice service is higher than that of other services, determines that the user uses the 4G network access according to the guarantee requirement of the voice service on the service quality, so as to provide network service with better coverage for the user, and sends the user identifier and the indication information ID of the access network category to the wireless network device as 1.
In step 323, the wireless network device learns that the user should use the 4G network for access according to the indication information ID of the access network type being 1, initiates a handover procedure, and switches the user to the 4G network.
Step 330 is the third service phase of the user, including steps 331-332.
at step 331, the user switches to WeChat during the voice call, which in turn opens browser services.
In step 332, the core network device senses the voice service of the user and other services such as WeChat and browser, judges that the priority of the voice service is higher than that of other services, and determines that the user uses 4G network access according to the guarantee requirement of the voice service on the service quality so as to provide network service with better coverage for the user.
Step 340 is a fourth service phase of the user, comprising steps 341 to 343.
at step 341, the user hangs up voice traffic.
In step 342, the core network device senses that the voice service of the user is finished, but services such as WeChat and browser still exist, determines that the user should keep network access of the current category to reduce network switching, and sends the user identification and indication information ID of the access network category to the wireless network device, which is 3.
in step 343, the wireless network device knows that the user should keep the network access of the current category according to the indication information ID of the access network category being 3, and therefore does not act.
The embodiment enriches the consideration factors for controlling the user to switch the network, thereby being capable of adapting to the complex network structure and various user requirements in the future network. The core network equipment can sense the change condition of the user service in real time and determine the currently suitable access network type of the user in time according to the current service of the user and the reference information for selecting the access network.
