When the eMTC service coexists with the trunking service, the network device needs to support the eMTC protocol and the B-Trunc protocol at the same time, and the performance requirements of the eMTC service and the trunking service need to be met at the same time on the shared air interface bandwidth. At present, how to uniformly allocate air interface resources of a cluster service and an eMTC service is not clear, and if the resource allocation is not reasonable, reliability of the cluster service and/or the eMTC service cannot be guaranteed.

In view of this, embodiments of the present invention provide a resource allocation method and apparatus, so as to implement a purpose of reasonably allocating resources for an eMTC service and a cluster service when the eMTC service and the cluster service coexist, so as to consider performance of the cluster service and the eMTC service.

Referring to fig. 1, a network device and a plurality of terminal devices form a communication system, where the network device is, for example, an evolved Node B (eNB or eNodeB) in Long Term Evolution (LTE), or a relay station or an access point, or a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved Public Land Mobile Network (PLMN) network, or a nodeb in an NR system, and the like. May be a device that provides voice and/or data connectivity to a user, a handheld device with wireless connection capability, or other processing device connected to a wireless modem. The terminal devices may be eMTC terminal devices or trunking communication terminal devices, or one and the same terminal device may simultaneously support eMTC service and trunking service, these terminal devices may communicate with one or more network side devices through a Radio Access Network (RAN), WIFI, wired network, and other network access devices, and the terminal devices may be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile devices, which exchange languages and/or data with the radio access network. For example, the terminal device 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), 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 in a future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited by the embodiments of the present invention. A terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a user device (user device), or a user equipment (user equipment), etc.

In the communication system, the terminal device is, for example, an eMTC terminal device or a trunking terminal device, or the same terminal device simultaneously supports an eMTC service and a trunking service, and the network device sends a service signaling to the terminal device or receives service data sent by the terminal device, for example, the network device sends an eMTC signaling, such as an eMTC public signaling and an eMTC private signaling, to the eMTC terminal device; for another example, the network device sends LTE public signaling, LTE private signaling, trunking voice service, trunking video service, trunking short message service, or the like to the trunking communication terminal device. Before the network equipment sends or receives various services or signaling, a resource pool of an empty port resource is divided, eMTC resources and LTE communication resources are divided from the resource pool, the eMTC resources are divided into high-priority resources and low-priority resources, the network equipment also divides the various services or signaling into different categories, the services or the signaling of the same category are stored in the same category set, and the category sets are sorted to obtain a first sequence. Then, according to the first sequence, resources are sequentially allocated to the classification sets. In the process of allocating resources, for a specific classification set, a second sequence corresponding to the classification set is determined, where the second sequence is used to indicate the sequence of high-priority resources, low-priority resources, or LTE communication resources, and then resources are allocated to the classification set according to the second sequence.

Next, a resource allocation method according to an embodiment of the present invention will be described in detail based on the architecture shown in fig. 1. For example, see fig. 2.

Fig. 2 is a flowchart of a resource allocation method provided in an embodiment of the present invention, where the embodiment describes the resource allocation method in detail from the perspective of a network device, and the embodiment includes:

101. classifying a plurality of services or signaling to obtain at least one classification set, wherein each classification set comprises at least one signaling, and the services or the signaling comprise: eMTC public signaling, eMTC private signaling, LTE public signaling, eMTC service, trunked voice service, trunked video service, or non-trunked service;

for example, the network device classifies services or signaling to be transmitted and/or services or signaling to be received, to obtain different classification sets, where each classification set includes at least one signaling or a service. Wherein the plurality of services or signaling comprise: eMTC common signaling, eMTC private signaling, LTE common signaling, eMTC traffic, trunked voice traffic, trunked video traffic, or non-trunked traffic.

102. Performing priority ordering on the at least one classification set to obtain a first order;

after the signaling set is obtained in step 101, in this step, the plurality of classification sets are sorted according to priority and the like, so as to obtain a first order, where the first order indicates a sequence of allocating resources for each classification set in the plurality of classification sets.

In addition, in the embodiment of the present invention, a first sequence of the plurality of classification sets may also be preset, and a subsequent network device is to send a service or a signaling, and/or put the service or the signaling into a corresponding classification set when the service or the signaling is to be received.

103. And according to the first sequence, sequentially allocating resources to each classified set from a resource pool.

In this step, the network device sequentially allocates resources, such as air interface resources, e.g., frequency domain resources, to each classification set in the classification set according to the first order. After distributing resources for each classification set, randomly extracting a service from the classification set and processing the service, such as sending the service or receiving the service; or after the resources are allocated to each classification set, processing each service or signaling according to the sequence of arrival of each service or signaling in the classification set.

In the resource allocation method provided in the embodiment of the present invention, when the eMTC service signaling coexists with the trunking service, the network device divides the services or the signaling into different categories to obtain a plurality of classification sets, sorts the classification sets according to the priority to obtain a first order, and allocates resources to each classification set in sequence from the resource pool according to the first order, so that the service with a high priority is allocated with resources first, and when the eMTC service coexists with the trunking service, the resources are allocated to the eMTC service and the trunking service reasonably, so as to achieve the purpose of considering the performance of the trunking service and the eMTC service.

In one possible implementation, the at least one classification set includes: an enhanced machine type communication (eMTC) public signaling set, an eMTC private signaling set, a Long Term Evolution (LTE) public signaling set, an LTE private signaling set, an eMTC service set, a trunking voice service set, a trunking video service set or a non-trunking service set; the first sequence is from front to back in sequence: the eMTC public signaling set, the LTE public signaling set, the eMTC private signaling set, the LTE private signaling set, the eMTC service set, the trunked voice service set, the trunked video service set, and the non-trunked service set.

In a feasible implementation manner, the resources in the resource pool include eMTC resources and LTE communication resources, the eMTC resources include high-priority resources and low-priority resources, the network device further determines a second order corresponding to each of the at least one classification set before allocating resources to each of the classification sets in the resource pool in sequence according to the first order, and the second order is used for indicating a sequence of the high-priority resources, the low-priority resources, or the LTE communication resources.

For example, for the eMTC common signaling set, the second order is from high priority resources to low priority resources, that is, the network device preferentially allocates resources for the eMTC common signaling set from the high priority resources, and if the resources in the eMTC common signaling set are not enough, the network device continues to allocate resources for the eMTC common signaling set from the low priority resources.

For another example, for the LTE common signaling set, the second order is to allocate resources from the LTE communication resources, the low priority resources to the high priority resources, that is, the network device preferentially allocates resources from the LTE communication resources to the LTE common signaling set, if the LTE communication resources are not enough, the network device continues to allocate resources from the low priority resources to the LTE common signaling set, and if the low priority resources are still not enough, the network device continues to allocate resources from the high priority resources to the LTE common signaling set.

For another example, for the eMTC-specific signaling set, the second order is from the high priority resource to the low priority resource, that is, the network device preferentially allocates resources for the eMTC-specific signaling set from the high priority resource, and if the high priority resource is not enough, continues to allocate resources for the eMTC-specific signaling set from the low priority resource.

As another example, for the LTE-specific signaling set, the second order is from LTE communication resources to low priority resources to high priority resources.

For another example, for the eMTC service sets, the second order is the high priority resources, that is, when the network device allocates resources to each classification set according to the first order, and when allocating resources to the eMTC service sets for the first time, only the eMTC service sets are allocated with resources from the high priority resources.

As another example, for the trunked voice traffic set, the second order is from LTE communication resources to low priority resources to high priority resources.

As another example, for the trunked video service set, the second order is from LTE communication resources to low priority resources to high priority resources.

As another example, for non-clustered service sets, the second order is from LTE communication resources to low priority resources to high priority resources.

Next, an embodiment is used to describe the foregoing resource allocation method in detail, for example, refer to fig. 3, fig. 3 is a flowchart of another resource allocation method provided in the embodiment of the present invention, where the embodiment includes:

201. the eMTC resources and the LTE communication resources are divided from the resource pool, and the eMTC resources are divided into high-priority resources and low-priority resources.

Illustratively, the network device allocates an air interface resource from the current subframe, and divides the eMTC resource and the LTE communication resource from the entire resource pool, or divides the entire resource pool into two parts, where one part is the eMTC resource and the other part is the LTE communication resource. Thereafter, eMTC resources are divided into high priority resources and low priority resources.

When the air interface resource is specifically a frequency domain resource, the frequency domain resource is Resource Blocks (RBs) one by one, and in general, 6 RBs form a Narrow Band (NB). Therefore, when dividing resources, the eMTC resources and the LTE communication resources may be divided from the resource pool in units of RBs, and further the eMTC resources may be divided into high priority resources and low priority resources in units of RBs, where the RBs included in the eMTC resources and the LTE communication resources may be continuous or discontinuous, and the resources included in the high priority resources and the low priority resources may be continuous or discontinuous. Alternatively, the eMTC resources and the LTE communication resources may be divided in units of NBs, and further divided into high-priority resources and low-priority resources, where the eMTC resources and the LTE communication resources include NBs that may be continuous or discontinuous, and the high-priority resources and the low-priority resources include resources that may be continuous or discontinuous.

202. The method comprises the steps of classifying a plurality of service signaling to obtain at least one classification set, and sequencing each classification set to obtain a first sequence.

Wherein, first order is from the front to back in proper order: the system comprises an eMTC public signaling set, an LTE public signaling set, an eMTC private signaling set, an LTE private signaling set, an eMTC service set, a trunking voice service set, a trunking video service set and a non-trunking service set.

203. Resources are allocated for the eMTC common signaling set.

Exemplarily, the network device determines a second sequence corresponding to the eMTC common signaling set, where the second sequence is from a high-priority resource to a low-priority resource, the network device preferentially allocates resources to the eMTC common signaling set on the high-priority resource, if the high-priority resource cannot meet the requirement, the network device continues to allocate resources to the eMTC common signaling set on the low-priority resource, and if the low-priority resource cannot meet the requirement, the network device fails to allocate resources to the current subframe eMTC common signaling set, and step 204 is executed; or, as long as the resources are successfully allocated to the LTE common signaling set, step 204 is executed, for example, if the resources are successfully allocated to the eMTC common signaling set from the high priority resource, step 204 is directly executed; for another example, if the high priority resource does not meet the demand, but the low priority resource meets the demand, step 204 is executed.

204. Resources are allocated for the LTE common signaling set.

Exemplarily, the network device determines a second sequence corresponding to the LTE common signaling set, where the second sequence is from LTE communication resources, low priority resources to high priority resources, the network device preferentially allocates resources to the LTE common signaling set on the LTE communication resources, if the LTE communication resources cannot meet the requirements, the network device continues to allocate resources to the LTE common signaling set on the low priority resources, if the low priority resources cannot meet the requirements, the network device continues to allocate resources to the cellular communication common signaling set on the high priority resources, and if the high priority resources still cannot meet the requirements, the network device fails to allocate resources to the LTE common signaling set, and step 205 is executed; alternatively, step 205 is performed as soon as the resources are successfully allocated for the LTE common signaling set.

205. Resources are allocated for the eMTC-specific signaling set.

Exemplarily, the network device determines a second sequence corresponding to the eMTC dedicated signaling set, where the second sequence is from a high-priority resource to a low-priority resource, the network device allocates resources for the eMTC dedicated signaling set on the high-priority resource, if the high-priority resource cannot meet the requirement, the network device continues to allocate resources for the eMTC dedicated signaling set on the low-priority resource, and if the low-priority resource cannot meet the requirement, step 206 is executed; alternatively, step 206 is performed whenever resources are successfully allocated for the eMTC-specific signaling set.

206. Resources are allocated for the LTE-specific signaling set.

Exemplarily, the network device determines a second sequence corresponding to the LTE dedicated signaling set, where the second sequence is from the LTE communication resource to the low priority resource and then to the high priority resource, and if none of the resources can satisfy the LTE dedicated signaling set, step 207 is executed; alternatively, step 207 is performed as soon as the resources are successfully allocated for the LTE-specific signaling set.

207. Resources are allocated for the eMTC service set.

For example, the network device determines that the second order corresponding to the eMTC service sets is the high priority resource, that is, the network device only allocates the resource to the eMTC service sets from the high priority resource, and if the resource allocation to the eMTC service sets fails, step 208 is executed; alternatively, if the eMTC service set is successfully allocated with resources, step 208 is performed.

208. And allocating resources for the cluster voice service set.

Exemplarily, the network device determines a second sequence corresponding to the trunking voice service set, where the second sequence is from LTE communication resources, low priority resources to high priority resources, and the network device preferentially allocates resources to the trunking voice service set at the LTE communication resources, if the LTE communication resources cannot meet the requirements, the network device continues to allocate resources to the trunking voice service set at the low priority resources, if the low priority resources cannot meet the requirements, the network device continues to allocate resources to the trunking voice service set at the high priority resources, and if the high priority resources still cannot meet the requirements, the network device fails to allocate resources to the current subframe trunking voice service set, and then step 209 is executed; alternatively, step 209 is performed whenever resources are successfully allocated for the set of clustered voice services.

209. And allocating resources for the eMTC service set which does not successfully allocate the resources.

For example, whether the resource is successfully allocated to the eMTC service set is determined, and if the resource is not successfully allocated to the eMTC service set, the resource is allocated to the eMTC service set according to the sequence from the high priority resource to the low priority resource. Thereafter, step 210 is performed.

210. And allocating resources for the cluster video service set.

Illustratively, the network device determines a second order corresponding to the cluster video service set, where the second order is all unused resources in the resource pool, including the high priority resource, the low priority resource, and unused resources in the LTE communication resource. If the network equipment judges that no residual resource exists in the resource pool, the resource allocation of the sub-frame cluster video service set fails, and the sub-frame scheduling process exits; if all the unused resources in the resource pool can meet the requirements of the cluster video service set and the resource pool has residual resources after the resources are allocated to the cluster video service set, executing step 210; alternatively, step 210 is performed as soon as the resource allocation for the cluster video service set is successful.

211. And allocating resources for the non-cluster service set.

In this step, the network device allocates resources to the non-trunking service set on the remaining resources in the resource pool, and if the remaining resources in the resource pool satisfy the non-trunking service set, the subframe scheduling process exits after the resources are allocated, and if the remaining resources in the resource pool cannot satisfy the non-trunking service set, the subframe scheduling process exits directly.

In a feasible design, the network device further determines whether the utilization rate of the target resource exceeds a preset threshold after allocating resources to each of the classified sets in sequence from the resource pool according to the first sequence; and if the utilization rate of the target resource exceeds the preset threshold value, increasing the target resource, wherein the target resource is any one of the LTE communication resource, the high-priority resource and the low-priority resource.

Illustratively, the network device may periodically adaptively adjust the LTE communication resources, the high priority resources, and the low priority resources. Taking the target resource as the high-priority resource as an example, the network device periodically counts the RB utilization rate of the high-priority resource, where the RB utilization rate of the high-priority resource is the number of RBs already used in the high-priority resource in the counting period/the total number of RBs in the high-priority resource in the counting period. If the utilization rate of the high-priority resource exceeds a preset threshold, judging whether the total number of the NB of the high-priority resource is greater than the number of the NB corresponding to the eMTC resource after the narrow band NB is added to the high-priority resource; and if the total number of the NBs of the high-priority resources is less than the number of the NBs corresponding to the eMTC resources, adding one NB in the high-priority resources.

Setting a preset threshold as Rate _ Th, if the utilization Rate of the RB of the high-priority resource is greater than Rate _ Th, adding 1 to the number of NBs in the high-priority resource by the network device, but the number of NBs corresponding to the high-priority resource cannot exceed the number of NBs corresponding to the eMTC resource; if the RB utilization Rate of the high-priority resource is less than or equal to Rate _ Th-offset, the network equipment subtracts 1 from the number of the NB in the high-priority resource, but the number of the NB corresponding to the high-priority resource cannot be less than or equal to 1. Wherein the offset is an offset value.
