Description

Resource processing method and device and communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource processing method and apparatus, and a communication device.

Background

In order to avoid a conflict between control plane network elements (such as SMF/PGW-C) or User plane network elements (such as UPF/PGW-U) when allocating an IP address/prefix of a UE (User Equipment), it is generally required that address pool resources of each control plane network element or User plane network element are independent from each other, that is, when a network is deployed, address pool resources of network elements related to network access need to be planned in advance.

However, in actual use, for a running network to which address pool resources have been allocated, there is a scenario of a new network entry network element or a network exit network element, and at this time, the address pool resources of the whole network (or one network element set) need to be re-planned, otherwise, the address pool of the new network entry network element cannot be configured, or the original address pool resources of the network exit network element are wasted.

When the network state of a network device changes in a network (whole network or a network element set), such as adding or removing a network element, how to make the IP address resources in the network be reasonably utilized is a problem to be solved.

Detailed Description

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a resource processing method, a resource transmission method, a device and equipment, which are used in a network in the prior art. The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

Fig. 1 is a schematic flow chart of a resource processing method according to an embodiment of the present invention. The method of the embodiment of the invention can comprise the following steps:

step 101, when detecting that the network status of a first network device in a target network changes, a first management device adjusts an IP address resource of the target network.

Here, the first management device may be an OAM (Operation Administration and Maintenance), an external server, or a control platform. If the IP address pool resource is controlled by SMF (Session Management Function)/PGW-C or UPF (User Plane Function)/PGW-U, the first Management device may be SMF/PGW-C or UPF/PGW-U that controls the IP address pool resource.

Here, the target network refers to a whole network, a network element set, or a regional region.

The first network device may be an SMF/PGW-C or UPF/PGW-U.

The IP address resource in the embodiment of the present invention may be an IP address or an IP address prefix.

According to the resource processing method provided by the embodiment of the invention, under the condition that the change of the network state of the first network equipment in the target network is detected, the IP address resource of the target network is adjusted through the first management equipment, so that the IP address resource in the network can be uniformly planned, and the purpose that the IP address resource in the network is reasonably utilized by each network equipment in the network is realized.

As an optional implementation manner, in step 101, when detecting that the network status of the first network device in the target network changes, the first management device adjusts an IP address resource of the target network, including:

the target IP address resource comprises at least one of:

IP address resources reserved by the first management device;

Here, the first management device, such as OAM, reserves available IP address resources, and the OAM may directly configure IP address resources for the first network device.

Here, the first management device, such as OAM, is used as an external server to generally maintain the UE IP address resource in the current network, when necessary, the SMF/PGW-C or UPF/PGW-U instantly acquires a specific address from OAM and allocates a corresponding session service, and when a session is established, updated, and released, the SMF/PGW-C or UPF/PGW-U also correspondingly notifies OAM. That is, the first management device itself can know the usage and remaining conditions of the UE IP address resources in the current network.

Here, the reason why the target IP address resource includes an IP address resource allocated to the second network device and unused by the second network device is that the IP address resource in the first management device has already been allocated or there is a remaining IP address resource in the first management device but is not in accordance with the demand of the first network device. For example, the associated DNN, S-NSSAI is not compliant with the first network device requirements.

Optionally, when the target IP address resource is a remaining IP address resource that is not allocated to the second network device by the current network; sending the first address resource to the first network device may include:

here, the network-related parameters include DNN, S-NSSAI, and the like.

here, the other IP address resources may be remaining unused IP address resources in a used IP address pool in the remaining IP addresses, and are not limited specifically here.

here, the allocation policy is that IP address resources are available for some special purpose, e.g. reserved for a particular user. The allocation policy based on the scenario is not prioritized by the first management device. Alternatively, the target user is a specific user that achieves a particular use.

It should be noted that, in other words, if there is a UE IP address resource that is just recovered to be available in the remaining IP address resources, in order to avoid a scenario that the target service is released for some reason but needs to be recovered later, the allocation policy is not prioritized by the first management device.

Optionally, when the target IP address resource is an IP address resource allocated to the second network device and not used by the second network device; before sending the first address resource to the first network device, the method of the embodiment of the present invention may further include:

here, if the IP address/prefix of the UE corresponding to the IP address resource of the second network device is allocated in the IP address pool identifier IP address pool ID manner, the policy may be adopted to directly report the complete unused IP address pool identifier to the first management device, and report the remaining available IP address resources in the used IP address pool.

here, the IP address resources available for some special purpose, for example, the IP address resources reserved for a specific user. And the third reporting strategy based on the scene is not prioritized by the second network equipment.

It should be noted that, if there is a UE IP address resource that is just recovered from the remaining IP address resources, in order to avoid a scenario that the target service is released for some reasons but needs to be recovered later, the worship reporting policy is not prioritized by the second network device.

It should be noted that, after reporting unused IP address resources by the second network device through the first statistical report response message, the second network device removes the reported IP address resources from its respective address pool.

Here, the first reporting policy has two sub-policies.

Reporting a part of address resources in the unused IP address resources in the second network device, wherein a ratio of the number of the part of address resources to the number of the unused IP address resources in the second network device is greater than a first preset threshold.

It should be noted that the first preset threshold may be 0.9. And the second network equipment reports most of unused IP address resources to the first management equipment in order to avoid the use requirement of a new IP address in the statistical process. Here, with this policy, the IP address resources available to the second network device itself are limited, and it is expected that IP address resources reallocated by the first management device will be received later.

And reporting a part of address resources in the unused IP address resources in the second network equipment, wherein the ratio of the number of the part of address resources to the number of the unused IP address resources in the second network equipment is less than a second preset threshold value.

It should be noted that the second preset threshold may be 0.1. The policy reports a small portion of unused IP address resources to the first management device. Here, with this device, the IP address resources available to the second network device itself are sufficient, and it is expected that the first management device is not required to reallocate the IP address resources subsequently.

It should be noted that the preset resource reporting policies may be used in combination.

Here, when the preset resource reporting policy is a preconfigured policy, that is, the second network device, such as the SMF/PGW-C and/or the UPF/PGW-U, is determined according to its own configuration. Further, to facilitate the unified processing of the first management device, it is preferable that each second network device adopts the same resource reporting policy.

As an optional implementation manner, sending the first address resource to the first network device may specifically include:

and sending a first IP address allocation request message to the first network device, wherein the first IP address allocation request message carries the first address resource.

Further, the method of the embodiment of the present invention may further include:

and receiving a first IP address allocation response message sent by the first network equipment.

It should be noted that, the first management device receives the first IP address allocation response message, which indicates that the first address resource allocated to the first network device is successfully allocated.

In a case that IP address resources need to be reallocated to second network equipment in a target network, how to allocate, as an optional implementation manner, after sending a first address resource to the first network equipment, the method of the embodiment of the present invention may further include:

The step may specifically include:

and sending a second IP address allocation request message to the second network equipment, wherein the second IP address allocation request message carries the second address resource.

Here, the second network device adds the received second address resource to the IP address resource pool of the second network device after receiving the second IP address allocation request message.

and receiving a second IP address allocation response message sent by the second network equipment.

It should be noted that, the first communication device receives the second IP address assignment response message, which indicates that the second address resource assigned to the second network device is successfully assigned.

As another optional implementation manner, in step 101, in a case that an on-network state change of a first network device in a target network is detected, the adjusting, by a first management device, an IP address resource of the target network includes:

Optionally, the recycling of the IP address resource used by the first network device when the first network device is on the network may include:

receiving a network quitting notification message sent by the first network device, wherein the network quitting notification message carries an IP address resource used by the first network device when the first network device is on the network;

here, when the first network device is needed in the network, the first management device may receive a network logout notification message sent by the first network device, for notifying the first network device that network logout is needed.

It should be noted that this step may be omitted if the logout operation itself is initiated by the first management device.

Or receiving a second statistical reporting request message sent by the first network device, where the second statistical reporting request message carries an IP address resource used by the first network device when the first network device is on the network;

or reading the IP address resource used by the first network equipment in the network in the pre-stored resource information record.

The first management device corresponding to the scenario reserves the IP address resource record allocated to the first network device for use in the network, so the first management device can directly read the record and recover the IP address resource used by the first network device in the network.

Here, after receiving the second statistical report request message sent by the first network device, the method of the embodiment of the present invention may further include:

and sending a second statistical reporting response message to the first network equipment.

Based on the implementation manner, optionally, the method of the embodiment of the present invention may further include:

How to send the third address resource may refer to the description of sending the first address resource and sending the second address resource, that is, sending the third address resource through the IP address allocation request message, where the message carries the third address resource, and details are not described here.

According to the resource processing method provided by the embodiment of the invention, under the condition that the network state of the first network equipment in the target network changes, the first network equipment receives the IP address resource adjustment of the first management equipment, so that the first management equipment is beneficial to uniformly planning the IP address resource in the network, and the purpose that the IP address resource in the network is reasonably utilized by each network equipment in the network is realized.

As an optional implementation manner, in step 201, in a case that an on-network state of a first network device in a target network changes, the first network device accepts an IP address resource adjustment of a first management device, including:

the target IP address resource comprises at least one of:

IP address resources reserved by the first management device;

and receiving a first IP address allocation request message sent by the first management device, wherein the first IP address allocation request message carries the first address resource.

Here, how to specifically receive the third address resource sent by the first management device may refer to the receiving of the first address resource part sent by the first management device, and also receive the third address resource through the IP address allocation request message, which is not described herein again.

Here, the first network device sends to the first management device the IP address resources it uses while on the net, with the purpose of providing candidate available IP address resources for subsequent adjustment of IP address resources in the target network by the first management device.

As an optional implementation manner, sending, to the first management device, an IP address resource used by the first network device when the first network device is on the network includes:

Here, when the first network device needs to be removed from the network, the first network device sends a network quit notification message to the first management device, so as to notify the first network device that the network quit is needed.

Here, after sending the second statistical report request message to the first management device, the method of the embodiment of the present invention may further include:

and receiving a second statistical reporting response message sent by the first management device.

The steps in the above implementation correspond to the steps of the embodiment section corresponding to the first management device.

Referring to FIG. 4, a network needs to add an SMF/PGW-C or UPF/PGW-U

s 1: the newly added SMF/PGW-C or UPF/PGW-U sends a network access notification message to the OAM;

it should be noted that this step is an optional step. This step may be omitted if the network entry operation itself is performed by OAM.

s 2: the OAM judges whether available UE IP address/prefix resources exist, if so, the UE IP address/prefix resources are directly distributed according to a preset strategy; if not, counting and recycling the available UE IP address/prefix resources in the network equipment;

1) if an available IP address pool resource is reserved in the OAM, the OAM may directly configure an address pool for the newly added SMF/PGW-C or UPF/PGW-U, and if so, the flow of the first embodiment is ended.

2) If OAM is used as an external server to maintain the UE IP/prefix resource in the current network as a whole, SMF/PGW-C or UPF/PGW-U instantly acquires a specific address from OAM and allocates corresponding session service when needed, and when the session is established, updated and released, the SMF/PGW-C or UPF/PGW-U correspondingly informs OAM, the OAM can acquire the use and residual situation of the UE IP address/prefix resource in the current network.

Here, the remaining IP address resources in the current network include: a complete unused IP address segment, IP address resources associated with network related parameters, IP address resources reserved for the target user, IP address resources obtained after the target service is released, and other IP address resources.

If so, the OAM may also directly configure the address pool for the newly added SMF/PGW-C or UPF/PGW-U, and its allocation policy is optional:

a. and preferentially allocating the IP address resources with the complete unused IP address field in the available UE IP address/prefix resources.

That is, if there is a complete unused IP address segment for some available UE IP address/prefix resources in the current network, such available UE IP address/prefix resources may be preferentially allocated to the newly added SMF/PGW-C and/or UPF/PGW-U.

b. Preferentially allocating IP address resources associated with network-related parameters from the available UE IP address/prefix resources, wherein the network-related parameters are associated with the newly added SMF/PGW-C and/or UPF/PGW-U;

that is, if some available UE IP addresses/prefixes in the current network are associated with some parameters, such as DNN, S-NSSAI, etc., and the newly-visited SMF/PGW-C and/or UPF/PGW-U are also associated with the above parameters in configuration, such available UE IP addresses/prefixes may be preferentially allocated to the newly-added SMF/PGW-C and/or UPF/PGW-U.

c. If the resources corresponding to the allocation strategy a and the allocation strategy b cannot meet the resource requirements of the newly added network access SMF/PGW-C and/or UPF/PGW-U, allocating other IP address resources except the d allocation strategy and the e allocation strategy;

d. and if the resources corresponding to the allocation strategy a, the allocation strategy b and the allocation strategy C cannot meet the resource requirements of the newly added network access SMF/PGW-C and/or UPF/PGW-U, allocating the UE IP address/prefix resource which is just recovered to be available.

The allocation policy is not an OAM prioritized allocation policy, i.e., is a non-prioritized allocation policy.

The purpose of this policy non-preferential allocation is to avoid scenarios where some traffic is released for some reason but needs to be restored later.

e. And if the resources corresponding to the allocation strategy a, the allocation strategy b and the allocation strategy C cannot meet the resource requirements of the newly added network access SMF/PGW-C and/or UPF/PGW-U, allocating some usable UE IP address/prefix resources with special purposes.

E.g., UE IP address/prefix resources reserved for a particular user.

3) If the address pool resources in the OAM have been allocated before, or even if there are remaining address pool resources that do not meet the requirements of the newly added network elements, i.e. the newly added SMF/PGW-C and/or UPF/PGW-U, if the associated DNN, S-NSSAI does not meet the requirements of the newly added network elements, the OAM needs to perform statistical recovery on the address resources available in the current network and allocate them to the newly added SMF/PGW-C or UPF/PGW-U. I.e. step s3 is performed.

s 3: OAM sends a statistical report request message to SMF/PGW-C and/or UPF/PGW-U of the network;

here, the SMF/PGW-C and/or UPF/PGW-U at the net, i.e., the network devices in the network that have not changed in the state of the net, i.e., the original SMF/PGW-C and/or UPF/PGW-U in the network.

Here, the statistics report request message is used to instruct the SMF/PGW-C and/or UPF/PGW-U on the network to report the currently available UE IP address/prefix resource.

Optionally, the statistical reporting request message carries a preset resource reporting policy.

s 4: and the SMF/PGW-C and/or UPF/PGW-U of the network reports at least part of available UE IP address/prefix resources based on a preset resource reporting strategy, reports the reported response message to OAM through statistics, and removes the reported UE IP address/prefix resources from respective address pools.

It should be noted that the preset resource reporting policy is configured in advance, or the preset resource reporting policy is carried in the statistical reporting request message.

The preset resource reporting strategy is configured in advance, namely determined according to the configuration of the preset resource reporting strategy.

The preset resource reporting strategy is carried in the statistical reporting request message, namely, the preset resource reporting strategy is issued through OAM.

Optionally, the preset resource reporting policy includes at least one of the following policies:

(1) reporting a majority of the available address resources in the SMF/PGW-C and/or UPF/PGW-U of the network to the OAM;

here, the policy is to avoid a new IP address usage requirement during the statistical process, and the SMF/PGW-C and/or UPF/PGW-U in the network reports most (e.g. 90%) of available address resources to be included in the statistical report response message according to the configuration or requirement, and sets a flag, in anticipation of receiving the IP address resources reallocated by OAM in steps 6a,7a, and 8 a.

(2) Reporting a small part of available address resources in the SMF/PGW-C and/or UPF/PGW-U of the network to OAM;

here, the SMF/PGW-C and/or UPF/PGW-U on the network reports a small portion (e.g., 10%) of its currently available UE IP address/prefix resources to the OAM in the statistics report response message according to its configuration or requirements, and sets a flag bit in anticipation of not requiring the IP address resources reallocated by the OAM.

(3) If the UE IP address/prefix resources of the SMF/PGW-C and/or UPF/PGW-U on the network are allocated in the form of IP address pool IDs, according to the configuration or requirement, the complete available IP address pool IDs are preferentially reported to the OAM, and the remaining available UE IP addresses/prefixes of the address pool that have already used part of the IP addresses can be reported at the same time.

(4) And the SMF/PGW-C and/or UPF/PGW-U of the network reports the newly recovered available UE IP address/prefix resource in a non-preferential manner according to the configuration or the requirement.

The purpose of the non-priority reporting of the strategy is to avoid a scenario that some services are released for some reasons but need to be restored later.

(5) And the SMF/PGW-C and/or UPF/PGW-U of the network reports the available UE IP address/prefix resources with certain special purposes in a non-preferential way according to the configuration or the requirement of the SMF/PGW-C and/or UPF/PGW-U.

Such as UE IP address/prefix resources reserved for a particular user.

It should be noted that the strategies (1) to (5) above may be used in combination.

For a certain SMF/PGW-C and/or UPF/PGW-U, at most one of the strategies (1) and (2) can be used.

For the SMF/PGW-C and/or UPF/PGW-U using the strategy (2), the reported IP address resources are all recovered by OAM, and when the step is executed after the step s5b, the whole process is ended;

if strategy (2) is not used, steps s5a, s5c, s6, s7, s8 need to be performed.

s5 a: and the OAM sends an IP address allocation request message to the newly added SMF/PGW-C and/or UPF/PGW-U, wherein the IP address allocation request message carries part of the available IP address/prefix resources obtained by the OAM.

It should be noted that, after receiving the statistics report response message, the OAM summarizes the available UE IP address/prefix reported by the original SMF/PGW-C and/or UPF/PGW-U in the network, and allocates a part of the available UE IP address/prefix to the newly added SMF/PGW-C or UPF/PGW-U through the IP address allocation request message according to the configuration or the requirement of the available UE IP address/prefix. Optionally:

(1) if the available UE IP addresses/prefixes reported by the SMF/PGW-C and/or UPF/PGW-U on the network are associated with some parameters, such as DNN, S-NSSAI, etc., and the newly added SMF/PGW-C and/or UPF/PGW-U are also associated with the above parameters in configuration, such available UE IP addresses/prefixes may be preferentially allocated to the newly added SMF/PGW-C and/or UPF/PGW-U.

s5 b: and the OAM sends an IP address allocation request message to the newly added SMF/PGW-C and/or UPF/PGW-U, wherein the IP address allocation request message carries all the resources of the available IP address/prefix resources obtained by the OAM.

s5 c: and the newly added SMF/PGW-C and/or UPF/PGW-U sends an IP address allocation response message to the OAM.

This step may be a step after step s5a or after step s5 b.

s 6: OAM sends IP address allocation request message to SMF/PGW-C and/or UPF/PGW-U of the network, the IP address allocation request message carries the remaining available IP address resources in OAM;

here, the remaining available IP address resources are the remaining available IP address resources except for the newly added SMF/PGW-C and/or UPF/PGW-U, among the available IP address/prefix resources obtained by OAM.

s 7: and after the SMF/PGW-C and/or UPF/PGW-U of the network receives the IP address allocation request message, adding the IP address/prefix resource reallocated from the OAM into the respective IP address pool.

s 8: and the SMF/PGW-C and/or UPF/PGW-U of the network sends an IP address allocation response message to the OAM.

Example two

Referring to FIG. 5, a network scenario requiring removal of one SMF/PGW-C or UPF/PGW-U

s 11: the SMF/PGW-C or UPF/PGW-U of the network quitting sends a network quitting notification message to the OAM;

it should be noted that this step is an optional step. This step may be omitted if the logout operation itself is performed by OAM.

Here, the network exit notification message may carry the UE IP address/prefix resource used by the network exit SMF/PGW-C or UPF/PGW-U when the network exits.

s12 a: and the SMF/PGW-C or UPF/PGW-U exiting the network sends a statistical report request message to the OAM, wherein the statistical report request message carries the UE IP address/prefix resource used by the SMF/PGW-C or UPF/PGW-U exiting the network when the network is on.

s12 b: and the OAM directly reads the record and acquires the UE IP address/prefix resource used by the network-quitting SMF/PGW-C or UPF/PGW-U when the network is in the quit state.

Here, the OAM keeps a record of the UE IP address/prefix resource used by the SMF/PGW-C or UPF/PGW-U previously allocated to the logout network when it is on the network, so the OAM can directly read the record and reclaim the relevant UE IP address/prefix resource.

It should be noted that s12a and s12b are optional steps.

s 13: and the OAM sends a statistical report response message to the SMF/PGW-C or UPF/PGW-U of the quit network.

This step corresponds to step s12 a.

s 14: and the OAM stores the UE IP address/prefix resource used by the SMF/PGW-C or UPF/PGW-U which exits the network when the network exists.

This step is an optional step, and if this step is executed, the flow of the second embodiment is ended.

s 15: and the OAM sends an IP address allocation request message to the SMF/PGW-C and/or the UPF/PGW-U of the network, wherein the IP address allocation request message carries the UE IP address/prefix resource used by the SMF/PGW-C or the UPF/PGW-U of the network quitting when the network is in the network.

This step is an optional step. That is, the OAM reallocates the UE IP address/prefix resource used by the withdrawn SMF/PGW-C or UPF/PGW-U on the network to other SMF/PGW-C and/or UPF/PGW-U on the network through the IP address allocation request message according to the configuration. Optionally:

(1) if some UE IP addresses/prefixes used by the descreened SMF/PGW-C or UPF/PGW-U are associated with parameters such as DNN, S-NSSAI, etc. and the services or addresses of some SMF/PGW-C or UPF/PGW-U existing in the network are also associated with these parameters, the OAM may preferentially assign these UE IP addresses/prefixes to these SMF/PGW-C or UPF/PGW-U.

(2) If some UE IP addresses/prefixes used by the descreened SMF/PGW-C or UPF/PGW-U are of special use, e.g., reserved for a specific user, and the services or addresses of some SMF/PGW-C or UPF/PGW-U existing in the network also serve the specific use, the OAM may preferentially allocate these UE IP addresses/prefixes to these SMF/PGW-C or UPF/PGW-U.

Note that the strategies (1) to (2) described above may be used in combination.

s 16: and after the SMF/PGW-C and/or UPF/PGW-U of the network receives the IP address allocation request message, adding the IP address/prefix resource reallocated from the OAM into the respective IP address pool.

s 17: and the SMF/PGW-C and/or UPF/PGW-U of the network sends an IP address allocation response message to the OAM.
