It should also be noted that reference to the terms "first \ second \ third" in the embodiments of the present application is only used for distinguishing similar objects and does not represent a specific ordering for the objects, and it should be understood that "first \ second \ third" may be interchanged with a specific order or sequence where possible so that the embodiments of the present application described herein can be implemented in an order other than that shown or described herein.
An embodiment of the present application provides a resource allocation method, as shown in fig. 1, where the method is applied to a terminal and may include:
s101, entering a first network, triggering an initiating process of a registration request message, and determining preselected slice information; the pre-selected slice information is slice information selected in advance from the signed slice information of the terminal.
The resource allocation method provided by the embodiment of the application is suitable for a scene of allocating network slice information to the terminal in the process of initial registration of the terminal when the terminal enters a first network.
In this embodiment of the present application, the first network may be a network that the terminal first enters, or may also be a network that the terminal does not first enter, and specifically, the first network may be selected according to an actual situation, and this embodiment of the present application is not specifically limited. For example, the scenario that the terminal enters the first network for the first time and performs initial registration may be: the terminal executes the operation of turning off the power or turning on the flight mode in the area 1, and after the terminal moves to the area 2, the terminal correspondingly executes the operation of turning on the power or turning off the flight mode, at this time, the terminal enters the network of the area 2 for the first time, and the terminal initiates initial registration in the network of the area 2.
In some embodiments, a terminal may be referred to as a User Equipment (UE). The Terminal may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) Station, a Personal Digital Assistant (PDA), or the like, and may also be a smart phone, a tablet computer, a palm computer, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), or the like, and may communicate with one or more Network devices through a Radio Access Network (RAN). For example, the terminal may be a mobile telephone (or so-called "cellular" telephone) or a computer having a terminal, etc., which may also be, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network. The terminal may also be a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a network evolved in the future, and the like, and the implementation of the present application is not limited.
The network device is a device for providing a wireless communication function for the terminal device, and includes but is not limited to: an evolved Node B (eNB or e-NodeB) in a Long-Term Evolution (Long-Term Evolution, LTE) system, a New air interface (NR) system, or an authorized-Assisted Access Long-Term Evolution (LAA-LTE) system, a micro Base Station (also referred to as a "small Base Station"), a pico Base Station, a Base Transceiver Station (BTS), a Base Band Unit (BBU), an Access Point (Access Point, AP), a Transmission Point (TP), or a New generation Node B (gNodeB).
In the embodiment of the application, after the terminal enters the first Network, the terminal needs to initiate a registration request message to the Network device, and the registration request message needs to carry Network Slice Information that the terminal desires to request, that is, Network Slice Selection Assistance Information (NSSAI), so that the terminal needs to determine the Network Slice Information that the terminal desires to request in a process of initiating the registration request message. Specifically, the terminal determines preselected slice information selected by an application layer of the terminal from slice information subscribed under a home network of the terminal, wherein the preselected slice information is Preferred NSSAI.
It should be noted that the slice information is a newly added function of the 3GPP in the 5G network, and the implementation process of the slice information is to divide a network entity into a plurality of logically independent networks and then allocate different network resources, such as bandwidth, rate, service quality, and the like, to each network, and in the process of allocating the network resources, different slice information may be allocated according to different service requirements, so that different network resources may be provided for different service scenarios more reasonably.
S102, adding at least part of the preselected slice information into the request mapping slice information cell, and adding the request mapping slice information cell into the registration request message.
In this embodiment of the present application, after determining the pre-selected slice information, at least part of the pre-selected slice information is added to the cell of the request mapping slice information, and specifically, the process of determining at least part of the pre-selected slice information includes: determining configuration slice information of a terminal; matching the configuration slice information with the pre-selection slice information, and adding the pre-selection slice information into the slice information cell requesting mapping under the condition that the configuration slice information is not matched with the pre-selection slice information; in case of detecting at least a partial match between the configuration slice information and the pre-selected slice information, adding slice information of the pre-selected slice information that matches the configuration slice information to the request map slice information element.
It should be noted that the configuration slice information may include at least one of allocated slice information corresponding to the first network, i.e., Allowed NSSAI, configuration slice information corresponding to the first network, i.e., Configured NSSAI, and pre-Configured slice information Configured in advance by the user, i.e., Requested NSSAI; the pre-selection slice information is slice information selected by an application module of the terminal from slice information signed under a home network of the terminal.
It should be noted that, if the terminal enters the first network for the first time, the configuration slice information record in the first network does not exist in the terminal, and at this time, it is detected that the configuration slice information does not match the pre-selected slice information.
It should be noted that, the above is only one application scenario in which the mismatch between the configuration slice information and the preselected slice information is detected, and other scenarios in which the mismatch between the configuration slice information and the preselected slice information can be realized are also within the protection scope of the present application, and are not described herein again.
It should be noted that, since the configuration slice information includes at least one of the allocated slice information corresponding to the first network, the configuration slice information corresponding to the first network, and the pre-configuration slice information pre-configured by the user, the process of matching the configuration slice information with the pre-selection slice information may be: whether an intersection part exists between the pre-selected slice information and the allocated slice information corresponding to the first network is determined, if the intersection part does not exist, whether the intersection part exists between the pre-selected slice information and the allocated slice information corresponding to the first network is further determined, if the intersection part does not exist, whether the intersection part exists between the pre-configured slice information and the pre-selected slice information pre-configured by a user is further determined, and if the intersection part does not exist, the configuration slice information and the pre-selected slice information are detected to be not matched.
Note that the information element requesting mapping slice information is in TS24.501 of 3GPP release above R16. In the current Protocol version, the request mapping slice information cell is applied in a scenario of a mobility update registration request, and is used for reporting subscription slice information related to a Protocol Data Unit (PDU) session activated by a Home Network, that is, a Home Public Land Mobile Network (HPLMN). In the embodiment of the application, an application scenario of the request mapping slice information cell is adjusted to be an initial registration scenario in a network roaming process, and the function of the request mapping slice information cell is adjusted to be that preselected slice information selected by an application layer from slice information subscribed under a home network of a terminal is reported, the request mapping slice information cell is multiplexed by the terminal in a process of entering a first network and performing initial registration, and the preselected slice information is added to the request mapping slice information cell.
Further, if there is an intersection between the pre-selected slice information and the allocated slice information corresponding to the first network, and/or there is an intersection between the pre-selected slice information and the configured slice information corresponding to the first network, and/or there is an intersection between the pre-selected slice information and the pre-configured slice information pre-configured by the user, at least a partial match between the configured slice information and the pre-selected slice information is detected, and the intersection between the configured slice information and the pre-selected slice information is the slice information in the pre-selected slice information that matches the configured slice information.
Further, matching slice information may also be added to the request slice information element. At this time, the request slice information cell is added to the registration request message and is sent to the network equipment.
As an example, an embodiment of the present application provides a process for mapping a slice information cell according to a pre-selected slice information filling request, as shown in fig. 2, where the process includes:
1. the terminal checks whether the current PLMN has the distributed slice information;
2. if the distributed slice information exists in the current PLMN, judging whether an intersection part exists between the pre-selected slice information and the distributed slice information;
3. if an intersection part exists between the preselected slice information and the distributed slice information, filling matched slice information between the preselected slice information and the distributed slice information into a cell requesting mapping of the slice information;
4. if the current PLMN does not have the allocated slice information, executing step 6;
5. if no intersection part exists between the pre-selected slice information and the allocated slice information, executing step 6;
6. checking whether configuration slice information exists in the current PLMN or not;
7. if the configuration slice information exists in the current PLMN, judging whether an intersection part exists between the pre-selection slice information and the configuration slice information;
8. if an intersection part exists between the preselected slice information and the configured slice information, filling matched slice information between the preselected slice information and the configured slice information into a cell requesting mapping of the slice information;
9. if the current PLMN does not have the matching slice information, executing 11;
10. if no intersection part exists between the pre-selected slice information and the matched slice information, executing 11;
11. checking whether pre-configured slice information configured by a user in advance exists;
12. if the pre-configuration slice information exists, judging whether an intersection part exists between the pre-configuration slice information and the pre-configuration slice information;
13. if an intersection part exists between the preselected slice information and the preconfigured slice information, filling matched slice information between the preselected slice information and the preconfigured slice information into a mapping request slice information cell;
14. if there is no preconfigured slice information, execute 16;
15. if there is no intersection between the pre-selected slice information and the pre-configured slice information, execute 16;
16. and filling the pre-selected slice information into the cell for requesting to map the slice information.
As an example, an embodiment of the present application provides a process for mapping a slice information cell to a matching slice information filling request between pre-selected slice information and allocated slice information of a current PLMN, as shown in fig. 3, and the specific implementation process includes:
1. the terminal checks whether the current PLMN has the distributed slice information;
2. if the distributed slice information exists in the current PLMN, judging whether an intersection part exists between the pre-selected slice information and the distributed slice information;
3. and if an intersection part exists between the preselected slice information and the allocated slice information, filling matched slice information between the preselected slice information and the allocated slice information into the cell of the slice information requested to be mapped.
For example, an embodiment of the present application provides a process of mapping a slice information cell with a matching slice information filling request between pre-selection slice information and configuration slice information of a current PLMN, as shown in fig. 4, and the specific implementation process includes:
1. the terminal checks whether the current PLMN has configuration slice information;
2. if the configuration slice information exists in the current PLMN, judging whether an intersection part exists between the pre-selection slice information and the configuration slice information;
3. and if an intersection part exists between the preselected slice information and the configured slice information, filling matched slice information between the preselected slice information and the configured slice information into the cell requesting mapping of the slice information.
For example, an embodiment of the present application provides a process of mapping a slice information cell to a matching slice information filling request between pre-selected slice information and pre-configured slice information pre-configured by a user, as shown in fig. 5, the specific implementation process includes:
1. checking whether pre-configured slice information configured by a user in advance exists;
2. if the pre-configuration slice information exists, judging whether an intersection part exists between the pre-configuration slice information and the pre-configuration slice information;
3. and if an intersection part exists between the preselected slice information and the preconfigured slice information, filling matched slice information between the preselected slice information and the preconfigured slice information into the mapping-requested slice information cell.
It should be noted that, the process of matching the pre-selection slice information with the configuration slice information of the current PLMN corresponding to fig. 4 may be performed after the pre-selection slice information corresponding to fig. 3 is not matched with the allocated slice information of the current PLMN, may be performed after the pre-selection slice information corresponding to fig. 5 is not matched with the pre-configuration slice information pre-configured by the user, may be performed first after the matching process between the pre-selection slice information and the configuration slice information of the current PLMN is performed, and/or may be performed after the pre-selection slice information is not matched with the configuration slice information of the current PLMN, the matching process between the pre-selection slice information corresponding to fig. 3 and the allocated slice information of the current PLMN is performed, and/or the matching process between the pre-selection slice information corresponding to fig. 5 and the pre-configuration slice information pre-configured by the user is performed, similarly, the execution sequence for matching the pre-selection slice information with the configuration slice information of the current PLMN corresponding to fig. 4 is also applicable to the matching process between the pre-selection slice information corresponding to fig. 3 and the allocated slice information of the current PLMN, and the matching process between the pre-selection slice information and the pre-configuration slice information pre-configured by the user corresponding to fig. 5. Specifically, the execution sequence between the preselection slice information corresponding to fig. 3 and the allocated slice information of the current PLMN, the matching between the preselection slice information corresponding to fig. 4 and the configuration slice information of the current PLMN, and the matching between the preselection slice information corresponding to fig. 5 and the preconfigured slice information configured in advance by the user may be selected according to the actual situation, and the embodiment of the present application is not particularly limited.
By way of example, the process of filling in the mapping slice information cell according to the pre-selected slice information may be: and directly filling the pre-selected slice information into the cell of the request mapping slice information. Or, after the pre-selection slice information corresponding to fig. 3 is not matched with the allocated slice information of the current PLMN, and/or after the pre-selection slice information corresponding to fig. 4 is not matched with the configuration slice information of the current PLMN, and/or after the pre-selection slice information corresponding to fig. 5 is not matched with the pre-configuration slice information pre-configured by the user, the pre-selection slice information is filled in the request mapping slice information cell. The specific execution sequence of mapping the pre-selected slice information filling request to the slice information cell may be selected according to the actual situation, and the embodiment of the present application is not particularly limited.
S103, sending the registration request message to the network equipment so that the network equipment can allocate network resources to the terminal according to at least part of the preselected slice information in the registration request message.
In the embodiment of the application, the terminal adds the request mapping slice information cell to the registration request message and sends the registration request message to the network device, and at this time, the terminal uploads at least part of the preselected slice information in the preselected slice information to the network device through the request mapping slice information cell.
In the embodiment of the application, when a network device receives a registration request message sent by a terminal, the network device searches at least part of preselected slice information from a request mapping slice information cell carried by the registration request message, configures allowed slice information according to a first association relationship between the at least part of preselected slice information and slice information allowed in a first network, and then returns the allowed slice information to the terminal through a registration response message, and the terminal selects the slice information in the first network according to the allowed slice information and in combination with own service requirements to establish a service path and perform data transmission, so as to realize a process that the network device allocates network resources to the terminal.
It can be understood that, since the cell requesting mapping slice information supports reporting of mapping slice information associated with a PDU session in a mobility update registration process, and the application context and the type of the carried information of the cell are extended, the terminal can send preselected slice information to the network device in time by requesting at least part of the preselected slice information uploaded by the cell requesting mapping slice information in a context where the terminal enters the first network and performs registration, thereby increasing the speed of establishing a service channel by the terminal and reducing the delay of a terminal service.

In the embodiment of the application, the terminal sends the registration request message carrying the request mapping slice information cell to the network device, and the network device searches the first network corresponding to the request mapping slice information cell and the registration request message from the registration request message.
It should be noted that, if the matched slice information is added to the slice information requesting cell, the network device searches the slice information requesting cell from the registration request message.
It should be noted that, in the initial registration process, the network device may receive a registration request message carrying a cell requesting mapping of slice information, or may receive a registration request message carrying a cell requesting slice information, and no matter which cell is received by the network device, a process of finding network slice information that the terminal desires to request from the network device needs to be performed.
S202, acquiring at least part of pre-selected slice information from the cell requesting mapping of slice information; the pre-selected slice information is slice information selected in advance from the signed slice information of the terminal.
In the embodiment of the application, after acquiring at least part of the preselected slice information from the cell requesting mapping of the slice information, the network device searches for the slice information allowed in the first network, and determines a first association relationship between at least part of the preselected slice information and the slice information allowed in the first network.
It should be noted that at least part of the pre-selected slice information includes slice information that matches the configuration slice information in the corresponding pre-selected slice information when the configuration slice information and the pre-selected slice information do not match, and when the corresponding total pre-selected slice information and the configuration slice information and the pre-selected slice information at least partially match.
And S203, configuring the allowable slice information by using at least part of the pre-selected slice information.
In the embodiment of the present application, the network device determines whether the slice permitted in the first network is associated with the preselected slice information, and configures corresponding permitted slice information in the registration response, otherwise further negotiates and re-determines the specific permitted slice information.
Further, if the network device searches the request slice information cell from the registration request message, the network device searches the matched slice information from the request slice information cell, and then the network device obtains a second association relationship between the matched slice information and the slice information permitted under the first network; and configuring the allowable slice information according to the second association relation.
