Abstract
The application discloses a resource allocation method in a cluster docking scene, which comprises the following steps: groups needing to be butted in the two cluster systems are divided into two types: a VIP guarantee docking group and a common docking group; configuring a vehicle platform for each VIP guarantee docking group; and configuring the rest vehicle platforms to the common docking group for shared use.

Description
Technical Field
The present application relates to the field of cluster communication technologies, and in particular, to a resource allocation method in a cluster docking scenario.
Background
Because the cluster systems are various, the voice interconnection and intercommunication among different cluster systems are always restricted by the butting with different systems. Even in some scenarios, even in the same standard, products of different manufacturers may not be able to interface system-level signaling due to technology or interface reasons. Therefore, it is currently common practice to interface through the trunking gateway + the vehicle station, as shown in fig. 1.
Cluster system a and cluster system B are two different cluster systems. If the group connection between the two systems is needed, each vehicle platform of the cluster system B is used as 1 user to open an account in the cluster system A, and the two cluster systems are communicated through the gateway channels and the vehicle platforms in a one-to-one correspondence mode. This approach can only achieve N: N static docking set configuration, i.e., N a system groups are in communication with N B system groups through N carriages. If a new group docking requirement appears, the configuration of the docking group needs to be manually modified, or a new vehicle platform needs to be added to complete docking.
Therefore, in the current implementation mode, the number of the vehicle platforms corresponds to the gateway channels one to one, the docking groups are limited by the number of the vehicle platforms, and the utilization efficiency of the docking group vehicle platforms is not high. In this docking manner, the number of carriages limits the number of groups to be docked, which becomes a bottleneck for docking two systems. How to guarantee that the call loss rate meets the requirement under the condition of limited number of the vehicle platforms and how to maximally complete the intercommunication of more groups of two systems becomes the difficult point of the cross-system butt joint at present.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
In order to solve the problems in the prior art, the invention provides a resource allocation method in a cluster docking scene.
It is assumed that there are a plurality of groups in the cluster system a and the cluster system B, and that there are M groups in the cluster system a and the cluster system B that need to be connected and communicated, and there are N carriages in the cluster system B. In general, N is much smaller than M. In order to realize reasonable distribution of limited N vehicle platform resources and maximally complete the butt-joint intercommunication of more groups of two cluster systems, the invention provides a scheme as shown in figure 2:
groups to be docked are divided into two types: the VIP ensures a docking group and a common docking group. Any group needing to be docked belongs to the class of a VIP guarantee docking group or a common docking group, the number of the VIP guarantee docking groups is less than that of the common docking groups, and the priority of the VIP guarantee docking group is higher than that of the common docking groups. Specifically, the method comprises the following steps:
the VIP guarantee docking group requires high performance and high call-through rate, so that a static configuration mode is adopted for the VIP guarantee docking group to configure a vehicle platform for each VIP guarantee docking group; if V groups belong to the VIP guarantee docking group, respectively configuring a vehicle platform for the V groups;
the common docking group allows a certain call loss rate, and the (M-V) common docking groups are provided with docking services by the (N-V) stations, namely, the rest (N-V) stations are configured to be shared by the (M-V) common docking groups.
For a group belonging to a common docking group, in order to guarantee service awareness and low time delay of a docking group with high activity as much as possible, how to reasonably distribute the (N-V) carriages needs to be considered, and for this reason, the invention provides the following solution.
Firstly, counting and sequencing the activity of a common docking group, and the specific method comprises the following steps:
firstly, a server in the cluster system a periodically (with a period of t) counts the service condition of each common docking group, including: the number of calls, the duration of calls, etc.;
then, representing the activity of each common docking group by calling times and/or calling duration, wherein the more the calling times, the higher the activity, and the longer the calling duration, the higher the activity;
and finally, sequencing the common docking groups according to the activity degree to obtain the sequencing of the common docking groups, wherein the more active groups indicate that the probability of future call is higher.
The following describes how to count the liveness of the common docking group by an example:
assuming that Pact represents the activity, the number of calls in t time is Nact, the call duration is Tact, the weight coefficient of the number of calls is a, the weight coefficient of the call duration is b, the weight of the impact of different service conditions on the group activity (i.e., the weight of the impact of the number of calls and the call duration on the activity) is represented by a and b, and a + b is 1, the activity of the group can be represented as:
Pact(t)＝a*Nact(t)+b*Tact(t)。
secondly, configuring a default group and a current group for each vehicle platform
As mentioned before, since (M-V) general docking groups require docking services to be provided by (N-V) carriages, one carriage will be configured with several groups. The vehicle platform can only reside under one group at a time, the group in which the vehicle platform currently resides is called the current group or the resident group of the vehicle platform, and the rest groups configured by the vehicle platform are called the scanning group of the vehicle platform.
Firstly, dividing a part of resources V from vehicle platform resources, using the resources V as a VIP resource pool, wherein the vehicle platforms in the VIP resource pool correspond to groups in a VIP guarantee docking group one by one, preferentially ensuring the docking requirements of the VIP guarantee docking group, not participating in sharing of the resources, and the current group of each vehicle platform in the VIP resource pool is the VIP guarantee docking group corresponding to the vehicle platform; and then, configuring the rest vehicle platforms to be shared and used by the common docking groups.
For how to configure the rest vehicle platforms to be shared and used by a common docking group, the following solutions are provided in the application:
dividing the rest vehicle platforms into n resource pools: r1 and R2 … … Rn, the number of the stations in each resource pool is R1、r2……rnWherein n is more than or equal to 1;
each period tnCounting and sorting the liveness of all the common docking groups, and taking the front (r) in the order from high to low according to the sorting1+r2+……+rn) Updating the default group list, and sequentially updating the current group for idle trolleys in the resource pools Rn-R1 according to the updated default group list;
each period tn-1To exclude the top r in the default group listnCounting and sorting the activity of the common docking groups except the common docking group, and taking the front (r) in the order from high to low according to the sorting1+r2+……+rn-1) After updating the default group list (r)1+r2+……+rn-1) A default group and according to the last (r) in the updated default group list1+r2+……+rn-1) The default groups are idle vehicle platforms in the resource pools Rn-1-R1 in sequence to update the current group;
by analogy, each period t1, pair is divided by the top (r) in the default group listn+rn-1+……r2) Counting and sorting the activeness of the common docking groups except the common docking group, and taking the front r from high to low according to the sorting1Last r of the update default group list1A default group according to the last r in the updated default group list1The default groups are idle vehicle platforms in a resource pool R1 to update the current group;
wherein t 2-tn is integral multiple of t 1.
The method and the device set different periods for different resource pools to update the current group and the default group, and aim to update the default group of each vehicle platform in the resource pool with higher stability at longer time intervals, so that the stability of the high-stability resource pool is maintained.
The above solution is illustrated below by two examples:
1. the remaining ride resources other than resource pool V are divided into two docking resource pools A, B, and satisfy N ═ V + a + B.
The resource pool a is a high-stability resource pool, the resource pool B is a low-stability resource pool, a reasonable proportion may be set, and (N-V) vehicle resources except for VIP resources are reasonably allocated to the resource pool a and the resource pool B, for example, a is (N-V) × 50%. In the following embodiment, it is assumed that the number of carriages in the high stable resource pool a is N1, and the number of carriages in the low stable resource pool B is N2.
And initially, according to the sequence of the activity degrees of the common docking groups from high to low, taking the first (N1+ N2) common docking groups to form a default group list, and sequentially configuring corresponding common docking groups for the carriages in the resource pool A and the resource pool B as a current group according to the default group list, wherein the activity degree of the current group of the carriages in the resource pool A is higher than that of the resource pool B. Higher liveness also means higher priority.
And setting a statistical large period T-N T, wherein N is an integer greater than 1.
In each small period t, counting and sequencing the activity degrees of the common docking groups except the first N1 common docking groups in the default group list, sequencing the activity degrees according to the counted activity degrees of the common docking groups, taking the first N2 rear N2 default groups of the updated default group list from high to low, and updating the current group for each idle vehicle platform in the B resource pool according to the rear N2 default groups in the updated default group list;
and in each large period T, counting and sequencing the activity degrees of all the common butt-joint groups, taking the first (N1+ N2) updated default group lists from high to low according to the sequencing, and sequentially updating the current groups for the idle trolleys in the resource pool A and the resource pool B according to the updated default group lists.
The purpose of setting the large period T is to update the complete default group list and the default group of each vehicle in the resource pool a at longer time intervals, so as to maintain the stability of the high-stability resource pool a.
2. The remaining vehicle platform resources except the resource pool V are not divided, and are only used as one resource pool, which is marked as a resource pool C, and N is equal to V + C.
For the vehicle platforms in the C resource pool, initially, the first C common docking groups can be taken according to the sequence of the liveness of the common docking groups from high to low to form a default group list, and the current group is configured for the vehicle platforms in the C resource pool in sequence according to the default group list. And in each period t, sequencing and updating the default group list according to the counted activity of the common docking groups, and updating the current group for each idle vehicle platform in the C resource pool according to the updated default group list.
Third, the processing of service call
As described above, the carriages in the resource pool a and the resource pool B respectively reside in a current group, the default group list is updated at a period T or T, and the server or the gateway maintains the default group list. If some non-current group in the common docking group has a call service, the common docking group needs to be set as the current group of a certain vehicle platform to provide a docking service for the common docking group. To this end, the solution of the invention is:
when a group in the common docking group has a call service, determining whether the group is a current group of a certain vehicle platform:
if the current group is the current group, directly calling, and when the calling is finished, judging whether the current group is a default group in a default group list, if the current group is the default group, the current group is not modified, and if the current group is not the default group and the non-default group does not restart the calling service after waiting for a set time T0, modifying the current group into the default group which is not set as the highest activity of the current group in the default group list;
if not the current group, then:
according to the activity sorting of the common docking groups, modifying the current group which is idle in the low-stability resource pool and has the lowest activity into the non-current group;
and if the low stable resource pool does not have the vehicle platform meeting the condition, modifying the current group which is idle in the high stable resource pool and has the lowest activity degree into the non-current group.
If there is a new non-current group with call service, then the modification is made according to the same method.
For the case of dividing n resource pools, the solution of the invention is:
when a group in the common docking group has a call service, determining whether the group is a current group:
if the current group is the current group, directly calling, and when the calling is finished, judging whether the current group is a default group in a default group list, if the current group is the default group, the current group is not modified, and if the current group is not the default group and the non-default group does not restart the calling service after waiting for a set time T0, modifying the current group into the default group which is not set as the highest activity of the current group in the default group list;
if not the current group, then:
according to the activity sorting of the common docking groups, modifying the current group which is idle and has the lowest activity in the resource pool R1 into the non-current group;
if the resource pool R1 does not have the vehicle platforms meeting the conditions, modifying the current group which is idle and has the lowest activity in the resource pool R2 into the non-current group;
and the rest can be analogized until the vehicle platform meeting the conditions is found.
And after the call of the non-current group is finished, waiting for a set time T0, and if the non-current group does not start the call service any more, restoring the current group of the vehicle platform to the default group.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
