Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
The concept of network sharing is proposed because the operator faces high spectrum license fees, network deployment costs, pressure to provide higher network coverage requirements within short term limits, and site deployment challenges. The network sharing means that different operators can share the same LTE wireless network, and meanwhile, the operators can be distinguished to configure air interface resources in proportion, and when a certain operator is idle, the air interface resources of the certain operator can be shared by other operators for use. And if the operators are not idle, the air interface resources are guaranteed to be used according to the proportion.
Based on the concept of network resource sharing, the embodiment of the invention provides a method for seizing cluster voice users across operators, which is applied to a cluster voice LTE wireless network system. The base station of the LTE wireless network system can flexibly allocate the proportion of uplink and downlink resources according to the service requirements of user equipment, and allocate the cluster voice user resources of idle operators to the cluster voice users of other operators needing the resources in time, so that the effective utilization of the resources is realized.
Fig. 1 is an application scenario diagram of the method for preempting trunking voice users across operators provided by the present invention, as shown in fig. 1, trunking voice users of different operators exist in a base station cell of an LTE network system, for example, operators in the base station cell include: operator A, operator B, operator C; user equipments a1, a2, a3 belong to carrier a's group voice users, user equipments B1, B2, B3 belong to carrier B's group voice users, and user equipments C1, C2, C3 belong to carrier C's group voice users. When the user equipment a1 of the operator A has service requirement and needs to use network resources, the user equipment a1 initiates request information of preemption to the base station.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart of an embodiment of a method for preempting a cluster voice user across operators according to the present invention, and as shown in fig. 2, the method includes the following specific steps:
s101, the main preempting user equipment sends request information of the cross-operator preempting to the base station, and the request information comprises an identification of a first operator serving the main preempting user equipment.
Before executing the step, if the main preemption user equipment receives the admission failure information sent by the base station, the main preemption user equipment tries to access the base station in a preemption mode, and sends the request information of the cross-operator preemption to the base station.
S102, the base station counts the RB utilization rate of the sum of the first resource block RB utilization rate and the second average RB utilization rate according to the identification of the first operator; the first RB utilization is an RB utilization of a trunked voice user of the first operator, and the second average RB utilization is an average RB utilization of the trunked voice user of the first operator.
The RB utilization rate of the trunking voice users of the first operator is the ratio of the total RB number distributed to the trunking voice users of the first operator by the base station to the total RB number which can be distributed by the base station, and the average RB utilization rate of the trunking voice users of the first operator is the ratio of the RB utilization rate of the trunking voice users of the first operator to the trunking voice user number of the first operator.
The resource block RB is the minimum unit of resource allocation in the LTE network system, the utilization rate of the resource block reflects the uplink and downlink communication conditions of the current cluster voice user, and it can be understood that the higher the utilization rate of the RB is, the busy service of the current cluster voice user is indicated.
Specifically, the base station obtains the total number of resource blocks RB allocated to all the trunking voice users of the first operator and the total number of resource blocks RB allocable by the base station, and calculates the RB utilization rate of the trunking voice users of the first operator, where the RB utilization rate reflects the resource usage of all the trunking voice users of the first operator at present.
One possible scenario in this embodiment: if the number of the trunked voice users of the first operator is 0, the average RB utilization rate of the trunked voice users of the base station is used to replace the second average RB utilization rate, that is, the average RB utilization rate of the trunked voice users of the first operator is replaced, so that the RB utilization rate of the sum of the RB utilization rate of the trunked voice users of the first operator and the average RB utilization rate of the trunked voice users of the base station is used as the determination subject of S103 to perform the determination.
Specifically, the average RB utilization rate of the cluster voice users of the base station is a ratio of the RB utilization rate of the cluster voice users of the base station to the number of the cluster voice users of the base station. Wherein the content of the first and second substances,
the RB utilization rate of the cluster voice users of the base station is the ratio of the total RB number distributed to all cluster voice users by the base station to the total RB number which can be distributed by the base station. Specifically, the base station obtains the total number of resource blocks RB allocated to all the clustered voice users of the current cell and the total number of resource blocks RB allocable by the base station, and calculates the RB utilization rate of the clustered voice users of the base station, where the RB utilization rate reflects the resource usage of all the clustered voice users of the current base station.
In this embodiment, for example, the base station receives request information for inter-operator preemption sent by the primary preempting user equipment a1 in S101, where the request information includes an identifier of the first operator a serving the primary preempting user equipment a 1. The base station acquires operator information serving the main robbing user equipment a1, namely an identifier of a first operator A of the main robbing user equipment a1, according to the received request information of the cross-operator preemption.
The base station counts the first RB utilization rate, namely the RB utilization rate of the trunking voice users of the first operator A according to the identification of the first operator A, and acquires the resource use conditions of all trunking voice users under the identification of the first operator A. Meanwhile, the base station needs to count the second average RB utilization rate, that is, the average RB utilization rate of the trunking voice users of the first operator, and obtain the average resource usage of the trunking voice users of the first operator in the current cell.
For the second average RB utilization described above, there is one possible case: the number of all clustered voice users under the current first operator identity is 0, for example, the main robbing user equipment a1 belongs to the operator a, and the base station counts that there are no clustered voice users belonging to the operator a except the main robbing user equipment a1, and then replaces the average RB utilization of the clustered voice users of the first operator a with the average RB utilization of the clustered voice users of the base station. Specifically, the base station needs to know the average resource usage of all clustered voice users in the current cell, that is, the average resource usage of all clustered voice users of the operator A, B, C in the current cell.
S103, the base station determines that the RB utilization rate is smaller than or equal to the resource proportion pre-allocated to the first operator by the base station, determines a preempted second operator, and determines the preempted user equipment in the user equipment served by the second operator.
The base station judges whether the RB utilization rate meets the requirement of inter-operator preemption according to the RB utilization rate obtained by the statistics of the S102, namely whether the RB utilization rate of the sum of the RB utilization rate of the cluster voice users of the first operator A and the average RB utilization rate of the cluster voice users of the first operator A is smaller than or equal to the resource proportion pre-allocated for the first operator by the base station. If the resource ratio is smaller than or equal to the resource ratio, it means that the first operator may further add a new user equipment for communication. And the base station allocates the resource information to be preempted for the main user equipment according to the judgment result.
Specifically, the base station needs to determine a second operator to be preempted, where the second operator is an operator other than the first operator, and the base station needs to determine whether the other operator meets the requirement of being preempted, that is, the base station needs to determine whether the second operator has excessive resource information; after determining the preempted second operator, the base station further determines the preempted user equipment according to the current use condition of the user equipment served by the second operator.
For example, on the basis of S102, the base station determines whether an RB utilization ratio, which is a sum of an RB utilization ratio of a trunking voice user of the first operator a and an average RB utilization ratio of the trunking voice user of the first operator a, meets a requirement of inter-operator preemption, where if the resource proportion pre-allocated by the base station to the first operator a is 20%, and if the RB utilization ratio of the first operator a is less than or equal to 20%, the main preempting user equipment a1 may preempt resource information of other operators except the first operator a. Further, the base station needs to determine whether the preempted second operator is operator B or operator C: if the second operator is determined to be operator B, it is further determined that the preempted user equipment under operator B is one of B1, B2 and B3; if the second operator is determined to be operator C, it is further determined that the user equipment preempted by operator C is one of C1, C2 and C3.
Optionally, the determining, by the base station, the second operator to be preempted includes:
a, a base station counts RB utilization rates of cluster voice users of other operators except a first operator; wherein, the first and the second end of the pipe are connected with each other,
the RB utilization rates of the trunking voice users of the other operators are respectively the ratio of the total RB number distributed by the base station to all trunking voice users of the other operators to the total RB number distributed by the base station to all trunking voice users of all operators. For example, in addition to the first operator a, the method further includes an operator B and an operator C, where the RB utilization of the trunked voice users of the operator B is a ratio of a total number of RBs allocated by the base station to all trunked voice users of the operator B to a total number of RBs allocated by the base station to all trunked voice users of all operators, and similarly, the RB utilization of the trunked voice users of the operator C is obtained.
B, the base station respectively judges whether the RB utilization rate of the cluster voice users of other operators exceeds the resource proportion pre-allocated by the base station for the other operators according to the RB utilization rate of the cluster voice users of the other operators; wherein the content of the first and second substances,
the proportion of the resources pre-allocated by the base station to other operators is fixed, and due to the special service requirements of the trunking voice users of the operators, the base station can re-allocate the resources according to the actual use condition, so that the resource use condition of individual operators exceeds the proportion pre-allocated by the base station at a certain moment. Under the new service requirement, the base station can perform resource preemption on the cluster voice users of the operators exceeding the resource allocation proportion through the judgment standard, so that relatively idle resources are effectively utilized.
And step C, the base station determines the operators with the RB utilization rate exceeding the resource proportion, and selects the operator with the most RB utilization rate exceeding the resource proportion as the second operator to be preempted.
And selecting the operator with the most excess resource proportion as the second preempted operator from the alternative operators with excess resource proportion. For example, if the RB utilization rates of the current operators B and C are 25% and 40%, respectively, and the preset resource proportions of the operators B and C are 20% and 30%, respectively, since the excess proportions of the operator B and the operator C are 5% and 10%, respectively, according to the selection criteria, the base station selects the operator C as the second operator to be preempted.
Optionally, the determining, by the base station, a robbed user equipment in the user equipments served by the second operator includes:
the base station determines to distribute and reserve the user equipment with the lowest ARP priority in the user equipment served by the second operator; and the base station takes the user equipment with the lowest ARP priority as the robbed user equipment.
For example, on the basis of step C, the base station selects operator C as the preempted second operator, where the user equipments served by the second operator include C1, C2, and C3, and the ARP priorities are C3> C1> C2, then the base station selects the user equipment C2 with the lowest ARP priority as the preempted user equipment.
And S104, the base station sends feedback information of the cross-operator preemption to the main preemption user equipment, wherein the feedback information comprises the resource information used by the preempted user equipment.
After the base station determines the second operator to be preempted and confirms the preempted user equipment in the user equipment served by the second operator, the base station sends feedback information of the cross-operator preemption to the main preempted user equipment, wherein the feedback information comprises the resource information which is used by the preempted user equipment and is used for indicating the main preempted user equipment to communicate with the base station according to the resource information. Specifically, the resource information includes channel information of the preempted user equipment and the base station.
For example, after determining the preempted user equipment at S103, the base station sends feedback information of the cross-operator preemption to the main preempting user equipment a1, the feedback information including resource information of the preempted user equipment (e.g., b1), the resource information including channel information of the user equipment b1 communicating with the base station.
The method for seizing the cluster voice users across operators provided by the embodiment of the invention comprises the steps that a base station acquires an identifier of a first operator of main robbing user equipment according to received request information for seizing the main robbing user equipment by expanding the operators, the identifier counts the RB utilization rate of the sum of the RB utilization rate of the cluster voice users of the first operator and the average RB utilization rate of the cluster voice users of the first operator, judges whether the RB utilization rate is smaller than or equal to the resource proportion pre-allocated to the first operator by the base station, if so, the base station allows the main robbing user equipment to seize across operators, and feeds the finally determined resource information of the robbed user equipment back to the main robbing user equipment for the communication between the main robbing user equipment and the base station. Through the setting, the base station can effectively distribute and manage the cluster voice user resources of different operators.
It should be noted that before the base station receives the request information of inter-operator preemption sent by the main preemption user equipment, the base station further includes a request admission message sent by the main preemption user equipment to the base station, and this action is used to confirm whether the main preemption user equipment can directly perform communication through base station admission before the above-mentioned embodiment. The alignment process is described in detail below using a detailed embodiment.
Fig. 3 is a flowchart of another embodiment of the method for preempting a group voice user across operators according to the present invention, as shown in fig. 3, before S101, the method of this embodiment may further include the following steps:
s201, the main robbing user equipment sends admission request information to the base station, and the admission request information comprises an identifier of a first operator serving the main robbing user equipment. Wherein the content of the first and second substances,
the request admission message is information that the main preemption user equipment initiates a request for directly accessing the base station before initiating the cross-operator preemption, and the message comprises the identification information of the first operator serving the main preemption user equipment.
S202, the base station counts the RB utilization rate of the cluster voice users of the base station.
The base station receives the admission request message sent by the main user equipment, and after acquiring the identification information of the first operator of the main user equipment requesting admission, counts the RB utilization rate of the cluster voice users of the base station, which is the same as the above embodiment and is not described herein again.
S203, the base station determines that the RB utilization rate of the cluster voice users of the base station is smaller than the preset admission parameter of the base station.
S204, the base station sends admission failure information to the main user equipment.
The base station judges whether the RB utilization rate is smaller than an admission parameter preset by the base station or not according to the RB utilization rate of the cluster voice users of the base station counted by the S202, and if the RB utilization rate of the cluster voice users of the base station is smaller than the admission parameter preset by the base station, the base station sends admission failure information to the main robbing user equipment; and if the RB utilization rate of the cluster voice users of the base station is greater than or equal to the preset admission parameters of the base station, the base station sends admission success information to the main user equipment. Wherein the content of the first and second substances,
the admission parameter preset by the base station is a configurable parameter RB _ Thd, the range is 0% -100%, the default value is 60%, and the default value is not specifically limited. When the RB utilization ratio of the cluster voice user of the base station is RB _ Thd, the base station sends admission success information to the main robbing user equipment; and when the RB utilization rate of the cluster voice users of the base station is less than RB _ Thd, the base station sends admission failure information to the main robbing user equipment. If the admission is successful, the main preemption user equipment can be directly accessed to the base station for communication, and if the admission is failed, the main preemption user equipment can also be accessed to the base station for communication in a cross-operator preemption mode.
The method of this embodiment is used for determining whether to allow the main preempting user equipment to directly access the base station for communication by judging the size relationship between the RB utilization rate of the cluster voice users of the base station and the admission parameters preset by the base station before the base station receives the cross-operator preemption message sent by the main preempting user equipment, and if the admission fails, the base station sends the feedback information of the admission failure to the main preempting user equipment to execute the subsequent step of cross-operator preemption.
