It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.

It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
In one embodiment, as shown in fig. 1, a routing policy updating method is provided, which may include:
step 202, outputting change information under the condition of meeting the updating condition of the routing strategy; the change information is used for indicating a network side to inquire a matched routing strategy; the updating condition of the routing strategy comprises any one or any combination of request for network access and occurrence of application program change;
wherein, the route selection refers to selecting a channel for transmitting information from a source node to a destination node through an interconnection network, and the information at least passes through one intermediate node; the routing strategy is URSP (UE route selection policy), each URSP rule of the URSP consists of a priority, a flow descriptor and a routing descriptor RSD list of the rule, the priority of each rule is different, each rule is sorted from high to low according to the priority, the priority determines the sequence of the UE using the URSP, and a terminal can route data to be sent by application according to one or more rules in the URSP, wherein the data to be sent by the application is routed to a Protocol Data Unit (PDU) session which is already established or a PDU session which is newly established so as to realize data transmission; the network side connects the call request or data request from the A port to different networks, and provides user connection, user management and service completion load as the interface of load network to external network; the network slice is a networking mode according to needs, an operator can separate a plurality of virtual end-to-end networks on a unified infrastructure, the network slice is suitable for various network environment requirements, resources are reasonably configured, limited networks are utilized, different network slices are configured according to different requirements of different services on the networks, and the operator can flexibly provide personalized network services for users according to third party requirements and network conditions. The SIM preset or the URSP preset by the terminal in the current routing policy update scheme has no pertinence, the network side may issue the same URSP to all terminals in the current cell, the slice management corresponding to the application program is not fine enough, and the current URSP rule, whether the issued rule or the rule preset by the terminal itself, cannot cover all the application programs of the terminal.
Specifically, under the condition that the updating condition of the routing strategy is met, the change information is output and used for indicating the network side to inquire the matched routing strategy; the routing strategy updating condition can comprise any one or any combination of request for network access and occurrence of application program change; when the terminal meets the routing strategy updating condition, the state of the terminal is changed, so that a required and more appropriate routing strategy needs to be configured for the terminal again. For example, when the terminal is powered on, the user requests to connect to the network, that is, the user requests to access to the network, the terminal may actively output corresponding change information to indicate the network side to query the matching routing policy, or when the user requests to reconnect to the network after going off the network, for example, when the normally used terminal enters a closed elevator and the user goes off the network, the user may re-request to connect to the network, that is, the user requests to access to the network again, the terminal may actively output corresponding change information to indicate the network side to query the matching routing policy, the network is restored when going out of the elevator, the user re-accesses to the network, and the terminal updates the local routing according to the routing policy queried by the network side, and when the terminal has an application program change, the terminal may also actively output corresponding change information to indicate the network side to query the matching routing policy.
In one embodiment, the step of outputting the variation information may further include:
the variation information is output through control plane signaling or user plane data transmission.
Specifically, in the case that the terminal satisfies the routing policy update condition, change information for indicating a network side to query for a matching routing policy may be output through Control Plane (CP) signaling (e.g., through Registration message) or user plane data transmission (UP transmission); if the change information contains less information quantity, the change information can be directly transmitted through a CP NAS (Network Attached Storage) signaling preferentially, the user data is put into the control plane data to be transmitted through the path, the information transmission speed is high, the time delay can be reduced, and a third route does not need to be established; if the amount of information contained in the change information is large, UP transmission can be selected, and the path only walks user data, so that the advantage that the transmission is fast when the amount of data is large and the user flow is not occupied is provided.
And step 204, if the routing strategy fed back by the network side is received, updating the local routing according to the routing strategy.
Specifically, under the condition that a routing strategy updating condition is met, the change information is output, and if a routing strategy fed back by the network side is received, it indicates that the network side has inquired a matched routing strategy and fed back, so that the terminal can update the local routing strategy according to the routing strategy fed back by the network side, thereby updating the local routing, further establishing a communication connection more suitable for the terminal state and the network, adapting to the changes of network flow and a topological structure, and improving the performance of network transmission.
The routing strategy updating method can output the change information under the condition that the terminal meets the routing strategy updating condition, the change information indicates the network side to inquire the matched routing strategy, and therefore the terminal updates the local routing according to the routing strategy fed back by the network side. The method and the device can actively report the change information when the terminal local application program APP changes, so that a network side configures a proper routing strategy according to different change information, and can also configure an independent routing strategy according to the change information reported by different terminals, namely, the method and the device can actively trigger the update process of the URSP when the local application program changes, and realize a refined slicing strategy. According to the method and the device, different paths (CP or UP) can be selected for reporting the change information according to the size of the reported information content or based on the consideration of time delay, so that the time delay is reduced or the user flow is not occupied, and the data transmission efficiency and the user experience are improved.
In one embodiment, the change information may include a set of application identifiers and user identification codes corresponding to the installed application programs;
the step of outputting the change information when the routing policy update condition is satisfied may include:
transmitting the change information to a network side under the condition of requesting network access; the change information is used for indicating the network side to inquire the user subscription data based on the user identification code and inquiring the set of the application identifiers corresponding to the application programs which are installed in a matching mode and the routing strategy of the user subscription data.
The application identifier corresponding to the application program can be a globally uniform and Unique application identifier (Unique APP ID), that is, each application program has its Unique identifier, and the application identifier corresponding to the application program can be uniformly allocated to international organization, so that each application program has its globally Unique ID (Identity document) and only a legitimate APP can have its Unique application identifier, which can ensure the security of the APP of the application program on the one hand and the uniformity of the application identifier corresponding to the APP of the application program under different networks on the other hand; the user identification code can be used for identifying the identity information of the user by the network; the subscriber subscription data may include an account opening and subscription information for the subscriber.
Specifically, under the condition of requesting for network access, updating through Registration messages or user plane up (user plane) data, and transmitting change information including a set of application identifiers corresponding to each installed application program and a user identification code to a network side through a wireless transmission network, so that the change information is used for indicating the network side to inquire user subscription data according to the user identification code and then inquiring a routing strategy matched with the user subscription data and the set of application identifiers corresponding to each installed application program; if the set of application identifiers corresponding to each installed application program is not changed, but if the users corresponding to the terminals are different, the routing strategies correspondingly matched at the network side are also different.
The application transmits the change information comprising the set of application identifiers corresponding to the installed application programs and the user identification codes to the network side under the condition of requesting network access, wherein the change information is used for indicating the network side to inquire the user subscription data according to the user identification codes, and queries the routing policy that matches the user subscription data and the set of application identifiers corresponding to each installed application, therefore, the application can inquire the user signing data by changing the user identification code in the information under the condition of requesting network access, and the network side is indicated to inquire the matched routing strategy through the user subscription data and the application identifier corresponding to each globally unique application program installed, and then the terminal updates local routing according to the routing strategy fed back by the network side, thereby realizing refined slice management and matching a more suitable routing management strategy for the terminal.

In the above, the application may actively output, to the network side, the change information including the set of application identifiers corresponding to each installed application program and the user identification code, so that the change information indicates that the network side queries the user subscription data according to the user identification code, and then queries the routing policy matching the user subscription data and the set of application identifiers corresponding to each installed application program; in the application, when the terminal changes the application program, for example, when the installed application program is increased or decreased, the terminal may actively transmit change information including the set of application identifiers corresponding to the installed application programs to the network side, so that the change information instructs the network side to directly query the routing policy matching the set of application identifiers corresponding to the installed application programs and the user subscription data. The method and the device can flexibly cope with the change of the application program installed on the terminal while ensuring the safety of the application program, the terminal outputs corresponding change information under the condition of meeting the updating condition of the routing strategy, the routing strategy required by the terminal is configured by indicating the network side, and the terminal with the changed application program is matched with the proper routing strategy in real time, namely, when the local application program is updated, the updating process of the URSP is actively triggered, refined slice management is realized, the accuracy of routing is improved, the communication connection between the terminal state and the network is established, the method and the device are suitable for the change of network flow and a topological structure, and the performance of network transmission is improved.
