Technical Field

Background

Currently, in the existing cellular mobile communication technology standard, a mobile network issues a slice configuration rule to a terminal, so as to instruct the terminal to bind with a slice connection identifier based on certain service characteristics (such as an application program identifier (Application Identity document, APPID), a fully defined domain name (Fully Qualified Domain Name, PQDN), a network interconnection protocol (Internet Protocol, IP) triplet, a data network name (Data Network Name, DNN) or a connection capability Connection Capability, and the like), establish a corresponding slice connection association relationship, and receive and transmit data through the slice connection.

The network can update rule parameters of the slice configuration rules (initial slice configuration rules) used by the terminal according to reasons such as service policies, network configuration and the like, and the terminal should operate on the original slice session connection according to the new updated slice configuration rules.

When the terminal operates the original slice session connection according to the new updated slice configuration rule, the terminal directly initiates a release flow to the slice session connection, and newly establishes the slice session connection according to the updated slice configuration rule, but in the process, the upper layer data communication service carried by the slice session connection is interrupted.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Before proceeding with the description of the specific embodiments, the following description is first made:

after the terminal has established a slice session connection according to the slice configuration rule, the following problems exist if an updated slice configuration rule is received:

initial state: the terminal first establishes slice session connection according to an initial slice configuration rule (labeled upsc=58) and configuration parameter information, and a schematic diagram of the slice configuration rule is shown in fig. 1.

Update state 1: the terminal receives the updated slice configuration rule (labeled upsc=58, the content is empty, and the deletion of the 58 # slice configuration rule and the corresponding slice session connection) from the network side device, and a schematic diagram of the updated slice configuration rule is shown in fig. 2.

Update state 2: the terminal receives the updated slice configuration rule (labeled upsc=59 and containing new configuration parameter content) sent by the network side device, and the terminal needs to reestablish slice session connection according to the updated slice configuration rule, where a schematic diagram of the updated slice configuration rule is shown in fig. 3.

After receiving the updated slice configuration rule, the terminal initiates a release-new process for the slice session connection, and during the switching, the upper layer data communication service carried on the slice session connection is interrupted.

Specifically, referring to fig. 4, fig. 4 is a timing chart of processing a slice session connection, and the specific flow is as follows:

t0: the terminal (User Equipment, UE) registers successfully in the 5G core network (5G Core Network,5GC);

t1: the UE initiates and completes the slice session connection #1 setup procedure using the slice identity S1 based on the existing slice configuration rules (e.g., 58# slice configuration rules, upsc=58, described above);

t2: the network side device issues to the UE an updated slice configuration rule (e.g., 58#,59 #) containing for slice session connection #1, specifying slice identity S2;

t2< T3: the UE releases the current slice session connection #1 during which the upper layer data transmission carried is interrupted.

T3: the UE uses the updated slice configuration rules (e.g., 59#, upsc=59 as described above), completes the new establishment of the slice session connection #2 using the new slice identifier S2, and resumes data transmission.

That is, when the terminal receives the updated slice configuration rule, the current slice session connection is released first, then the slice session connection is newly established according to the updated slice configuration rule, and during the period of the release of the original slice session connection and the establishment of the new slice session connection (T2 < T3), the carried data information is interrupted (the session of the underlying protocol is carried and interrupted, the interruption time delay is between 1s and 10s, the data transmission of the application layer is interrupted, and the interruption time delay is increased by more than 5 s). The current slice session connection release-reconstruction process adopted by the terminal leads to interruption of the carried upper layer data communication service and obvious user service experience deterioration.

In order to solve the problem that when a terminal operates an original slice session connection according to an updated slice configuration rule, the terminal directly initiates a release flow to the current slice session connection, and establishes a new slice session connection according to the updated slice configuration rule to cause interruption of an upper layer data communication service carried by the slice session connection.

As shown in fig. 5, a communication processing method is applied to a terminal, and the method includes:

step 501: and under the condition that the terminal establishes the first slicing session connection according to the first slicing configuration rule, if a second slicing configuration rule aiming at the first slicing session connection is received, comparing a first configuration parameter corresponding to the first slicing configuration rule with a second configuration parameter corresponding to the second slicing configuration rule to obtain a parameter comparison result.

Alternatively, the terminal may be a wireless communication device, a mobile device, a user terminal, a handheld device with wireless communication function, a computing device, or may be another processing device connected to a wireless modem, an in-vehicle device, or a wearable device.

The first configuration rule and the second configuration rule are sent to the terminal by the network side device, and optionally, the network side device may be a core network element.

For example, the first slice configuration rule is a slice configuration rule corresponding to upsc=58 as shown in fig. 1, and the second slice configuration rule is a slice configuration rule corresponding to upsc=59 as shown in fig. 3.

In this step, after the terminal has established the first slice session connection according to the current slice configuration rule (first slice configuration rule), if an updated slice configuration rule (second slice configuration rule) applicable to the first slice session connection is received, the terminal compares the configuration parameters of the first slice configuration rule and the second slice configuration rule, that is, compares the first configuration parameters corresponding to the first slice configuration rule with the second configuration parameters corresponding to the second slice configuration rule, so as to obtain a parameter comparison result.

Step 502: and processing the slicing session according to the parameter comparison result.

In this step, the terminal performs the processing of slicing session connection according to the result of comparing the parameters of the first configuration parameter and the second configuration parameter.

Optionally, the processing for making slice session connection includes at least one of:

slice connection parameter configuration information.

That is, when comparing the first configuration parameter and the second configuration parameter to obtain a parameter comparison result, at least one of the following parameters is mainly compared between the first configuration parameter and the second configuration parameter:

priority of slice configuration rules;

traffic flow characterization information (Traffic Descriptor);

slice connection parameter configuration information.

name information for identifying a service or an application;

type information for identifying a service or application;

fully qualified domain name FQDN;

An access point name;

connection capability type.

a data network name DNN;

Wherein the network slice identity is e.g. single network slice selection assistance information (single network slice selection assistance information, S-NSSA); the IP address types of slice connections include IPv4, IPv6, IPv4v6, ethernet.

Optionally, the parameter comparison result is used to indicate one of:

That is, the parameter comparison result includes 5 types, wherein the parameter comparison result type 1: the service flow characteristic description information (second service flow characteristic description information) in the second configuration parameter is unchanged relative to the service flow characteristic description information (first service flow characteristic description information) in the first configuration parameter, but the slice session connection parameter configuration information (second slice session connection parameter configuration information) in the second configuration parameter is changed relative to the slice session connection parameter configuration information (first slice session connection parameter configuration information) in the first configuration parameter, namely that updating of the slice configuration rule belongs to updating and adjusting the connection parameter configuration of the first slice configuration rule, namely that in the comparison of the configuration parameters of the first slice configuration rule and the second slice configuration rule, the service flow characteristic description information number and the slice connection parameter configuration information are partially changed;

parameter comparison results type 2: the service flow characteristic description information (second service flow characteristic description information) in the second configuration parameter is unchanged relative to the service flow characteristic description information (first service flow characteristic description information) in the first configuration parameter, the slice connection parameter configuration information (second slice connection parameter configuration information) in the second configuration parameter is unchanged relative to the slice connection parameter configuration information (first slice connection parameter configuration information) in the first configuration parameter, but the serial number (second serial number) of the slice configuration rule in the second configuration parameter is changed relative to the serial number (first serial number) of the slice configuration rule in the first configuration parameter or the priority (second priority) of the slice configuration rule in the second configuration parameter is changed relative to the priority (first priority) of the slice configuration rule in the first configuration parameter, namely that the update of the slice configuration rule belongs to update adjustment of the serial number or priority of the current slice configuration rule, namely that in the comparison of the configuration rule of the first slice configuration rule and the configuration rule with the configuration rule of the second slice configuration rule, the service flow characteristic description information and the slice configuration rule are kept the same or the priority of the configuration rule is changed;

Parameter comparison result type 3: the service flow characteristic description information (second service flow characteristic description information) in the second configuration parameter presents new service flow characteristic description information relative to the service flow characteristic description information (first service flow characteristic description information) in the first configuration parameter, namely, the update of the slice configuration rule belongs to the new addition of the service flow characteristic description information, namely, the new service flow characteristic description information appears in the comparison of the configuration parameters of the first slice configuration rule and the second slice configuration rule;

parameter comparison result type 4: the sequence number of the slice configuration rule in the second configuration parameter (second sequence number) is unchanged relative to the sequence number of the slice configuration rule in the first configuration parameter (first sequence number), and other information in the second configuration parameter is null, or the priority of the slice configuration rule in the second configuration parameter (second priority) is unchanged relative to the priority of the slice configuration rule in the first configuration parameter (first priority), and other information in the second configuration parameter is null, and the first configuration parameter includes, for example, the sequence number of the first slice configuration rule (labeled upsc=58) as shown in fig. 1, and the second configuration parameter includes the sequence number of the second slice configuration rule (labeled upsc=58, and content is null) as shown in fig. 2.

Parameter comparison result type 5: the second configuration parameter being different relative to the first configuration parameter includes the second configuration parameter being all or partially different relative to the first configuration parameter.

Under the condition that the parameter comparison result is the parameter comparison result type 1, the terminal applies a second slice configuration rule to carry out slice session connection processing, and the process comprises the following steps: the terminal initiates the establishment of a new slicing session connection (second slicing session connection) according to the second slicing configuration rule, after the second slicing session connection is successfully established, the data path received and sent on the first slicing session connection is migrated to the second slicing session connection, namely, the data transmitted on the first slicing session connection is migrated to the second slicing session connection for transmission, and after the upper layer of the terminal completes the transfer of the data path, the first slicing session connection is released.

Further, the transferring the data transferred on the first slicing session connection to the second slicing session connection for transfer includes:

In the case that the parameter comparison result is the parameter comparison result type 1, please refer to fig. 6 for a specific flow of the processing of slicing session connection by the terminal, the terminal bottom layer receives a first slicing configuration rule sent by the network side device, establishes a first slicing session connection (slicing session connection # 1) according to the first slicing configuration rule, the data of the terminal upper side and the terminal bottom layer are received and transmitted on the slicing session connection #1, the terminal receives a new slicing configuration rule (second slicing configuration rule) issued by the network side device, compares configuration parameters of the first slicing configuration rule and the second slicing configuration rule, if the parameter comparison result is the parameter comparison result type 1, the terminal determines to apply the second slicing configuration rule, initiates a session connection request, the second slicing session connection (slicing session connection # 2) is established successfully, the terminal bottom layer immediately reports success of slicing session connection #2 to the terminal, that is sent to the upper layer of the terminal, the first indication information is used for indicating success of establishment of the second slicing session connection (slicing session connection # 2), the terminal bottom layer sends a message indicating success of receiving the data of the new slicing session connection #2 to the terminal through the terminal connection on the upper layer after the terminal bottom layer sends the success of the data of the connection #2 to the terminal connection through the slicing connection.

Wherein the first indication information has the communication processing of the highest priority.

In the information communication between the terminal bottom layer and the terminal upper layer, the terminal bottom layer should immediately report to the terminal upper layer that a new slice session connection (second slice session connection) is established by adopting a communication mechanism with the highest priority (such as an interrupt request, an event trigger and the like), and the first indication information can improve the timeliness of reporting to the terminal upper layer by adopting the communication mechanism with the highest priority, thereby reducing unnecessary time delay caused by the delay of the internal message report.

Further, the releasing the first slicing session connection includes:

With continued reference to fig. 6, after the upper layer of the terminal completes the migration of the data path, the upper layer of the terminal transmits a second indication message to the lower layer of the terminal, where the second indication message indicates to release the first slice session connection (slice session connection # 1), and the lower layer of the terminal initiates a connection release request of the slice session connection #1 to the network side device, i.e. releases the slice session connection #1 according to the second indication message.

In the embodiment, the terminal bottom layer immediately reports that a new slice session connection is established to the terminal upper layer, so that the inter-layer waiting interruption time delay can be reduced; and the upper layer of the terminal starts to use a new slice session connection service, so that the session migration switching time delay is reduced.

Aiming at the current situation that the slice configuration rule is reconfigured, the embodiment of the invention improves the implementation method that the terminal releases the original slice session connection and then newly establishes the new slice session connection, adopts the implementation method that the new slice session connection is established firstly and releases the original slice session connection, improves the instantaneity of communication between the bottom layer and the upper layer in the terminal, and has the advantage of obviously reducing the interruption of the transmission of upper layer data information caused by updating the slice configuration rule.

Further, the method further comprises:

and saving the second slice configuration rule as a current configuration rule.

Further, the method further comprises:

and deleting the first slice configuration rule.

And after the terminal establishes the second slice session connection according to the steps and releases the first slice session connection, the second slice configuration rule is stored as the current configuration rule, and the original first slice configuration rule is deleted.

Optionally, the method further comprises:

And under the condition that the parameter comparison result is the parameter comparison result type 1, in the process of carrying out the processing of slicing session connection by the terminal through applying the second slicing configuration rule, the terminal initiates to establish a new slicing session connection (second slicing session connection) according to the second slicing configuration rule, and if the second slicing session connection is failed to establish, the terminal keeps the first slicing session connection to carry out data transmission.

That is, if the parameter comparison result is the parameter comparison result type 2, if the priority level of the serial number of the slice configuration rule in the second configuration parameter is higher than the priority level of the serial number of the slice configuration rule in the first configuration parameter (the value of the second serial number is smaller than the value of the first serial number), or if the priority level of the slice configuration rule in the second configuration parameter is higher than the priority level of the slice configuration rule in the first configuration parameter, the terminal maintains the current first slice session connection, and keeps transmitting the upper layer data through the first slice session connection.

The parameter comparison result is the parameter comparison result type 2, that is, the slice connection parameter configuration of the first slice configuration rule and the second slice configuration rule is the same, the terminal can use the original slice session connection (first slice session connection), the first slice session connection is not required to be dismantled, the operation process of new slice session connection is newly established, and unnecessary service interruption is reduced.

Further, the method further comprises:

and saving the second slice configuration rule as a current configuration rule.

And under the condition that the parameter comparison result is the parameter comparison result type 2, the terminal keeps the current first slice session connection, and after the transmission of the upper layer data is carried out through the first slice session connection, the terminal can store the second slice configuration rule as the current configuration rule.

And under the condition that the parameter comparison result is the parameter comparison result type 3, the terminal initiates a process of establishing a new slice session connection (second slice session connection) according to a second configuration rule, and receives and transmits data matched with the new service flow characteristic description information on the newly established second slice session connection according to the second slice configuration rule.

Further, the method further comprises:

and saving the second slice configuration rule as a current configuration rule.

And under the condition that the parameter comparison result is the parameter comparison result type 3, the terminal initiates a process of establishing second slice session connection according to a second configuration rule, and according to the second slice configuration rule, the terminal receives and transmits data matched with the new service flow characteristic description information on the newly established second slice session connection, and then the second slice configuration rule is used as a current configuration rule to be stored.

In the case that the parameter comparison result is the parameter comparison result type 4, that is, the serial number or the priority of the slice configuration rule is unchanged, but the rest of configuration information is null, the transmitted data on the slice session connection (the first slice session connection) configured by the original slice configuration rule needs to be migrated to the slice session connection corresponding to the other slice configuration rule for transmission, and then the first slice session connection is released and deleted.

The specific flow of the terminal for slicing session connection is as follows: the terminal bottom layer receives third indication information sent by the terminal upper layer, wherein the third indication information is used for indicating that the first slice session connection is to be released and deleted; after receiving the third indication information, the upper layer of the terminal transfers the data transmitted on the first slice session connection to a third slice session connection for processing, wherein the third slice session connection is configured according to configuration rules except the first slice configuration rule and the second slice configuration rule; after the upper layer of the terminal completes data migration, fourth indication information is sent to the bottom layer of the terminal, the fourth indication information is used for indicating the bottom layer of the terminal to release and delete the first slicing session connection, and after the bottom layer of the terminal receives the fourth indication information, the first slicing session connection is released and deleted.

In the case that the terminal adopts the connection reconfiguration process based on the current slice session connection, if the parameter comparison result is the parameter comparison result type 5, that is, the configuration rule (first slice configuration rule) applied to the current slice session connection (first slice session connection) is partially different or completely different from the configuration parameter of the updated slice configuration rule (second slice configuration rule), the terminal applies the updated slice configuration rule to reconfigure (update) the slice session for the first slice session connection.
