Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling service multicast resources.
Background
In order to effectively utilize mobile network resources, 3GPP organizations have proposed Multimedia Broadcast Multicast Service (MBMS), which can implement point-to-point or point-to-multipoint services for transmitting data from one data source to a single user or multiple users according to the number of Service users, and implement network resource sharing, including resource sharing of a mobile core network and an access network, especially air interface resources.
For a Multicast Control Channel (MCCH) in an MBMS, when the configuration of the MCCH needs to be changed, since the minimum update period of the configuration change is 512 radio frames, if an air interface Multicast resource is established in real time, a terminal cannot acquire the MCCH configuration quickly in time. Therefore, in the prior art, a mode of pre-establishing a multicast resource at an air interface is adopted to solve the above problem, that is, before an MBMS group service is established, according to a requirement of the group service on a Guaranteed Bit Rate (GBR), a required Single Frequency Network Multicast (MBSFN) subframe resource is allocated to each MBMS group service, and the MBSFN subframe resource remains unchanged after allocation until the current MBMS group service is stopped. Since the MBSFN subframe resources are transmitted through the MCCH and remain unchanged after the MBSFN subframe resources are allocated, the configuration of the MCCH is not changed.
However, in order to ensure that the MBMS group service is allocated with MBSFN subframe resources as much as possible, the allocation is performed according to the maximum number of MBMS groups. However, in actual use, not all MBMS groups are in multicast service, that is, not all MBSFN subframe resources are used for multicast transmission, thereby causing resource waste.

Fig. 2 is a flowchart of a first embodiment of a method for controlling service multicast resources according to the present invention. As shown in fig. 2, the execution subject of the method provided by the present invention may be a network device. The method for controlling service multicast resources provided by the embodiment comprises the following steps:
s101, acquiring the number of service multicast resources which are pre-established in the service area SA and are idle currently, and recording the number as a first number.
In this embodiment, the service multicast resource is used to be allocated to a group subscribed in the SA, so as to perform multicast communication. If the service multicast resource is currently allocated to the group signed in the SA, the service multicast resource is not idle at present, namely occupied. And if the service multicast resource is not currently allocated to the group signed in the SA, the service multicast resource is currently idle.
The first number in this embodiment may be the number of service multicast resources pre-established for the first time in the SA, or the number of idle service multicast resources controlled by the service multicast resource control method in this embodiment.
Before step S101, the service multicast resource needs to be pre-established for the first time. At this time, since the pre-established service multicast resources are not allocated to the group subscribed in the SA, all the pre-established service multicast resources are set to be idle. Optionally, the number (denoted as N) of the first pre-established service multicast resources in the SA may be obtained according to the number (denoted as M) of the groups subscribed in the SA and the preset ratio 1 (denoted as P1). For example: multiplying the M by the P1, and then rounding up to obtain a value as the N. The preset proportion 1 is set according to the average activation rate of the service, so that the requirement of the group in the SA on the service multicast resource can be met as much as possible by the pre-established service multicast resource.
S102, obtaining the maximum number of the multicast resources of the current services needing to be pre-established, and recording the maximum number as a second number.
The second number in this embodiment is the maximum number of idle service multicast resources that can meet the requirement of a group in the current SA for a service multicast resource, and one service multicast resource corresponds to each group.
S103, adjusting the pre-established idle service multicast resources according to the first number, the second number and the third number.
Wherein, the third number is the minimum threshold value of the number of idle service multicast resources. The minimum threshold value of the number of the idle service multicast resources is to ensure that the number of the service multicast resources can meet the requirement of the group on the service multicast resources when the group in the SA requires the service multicast resources concurrently. Alternatively, the third number may be a predetermined value, and may be stored in the network device, for example.
In this embodiment, after the first number and the second number are obtained, the pre-established idle service multicast resource is adjusted according to the first number, the second number, and the third number, so that the adjusted pre-established idle service multicast resource just meets the multicast requirement of the group in the SA.
In the method for controlling service multicast resources provided in this embodiment, by obtaining the number of service multicast resources pre-established and currently idle in the SA, obtaining the maximum number of idle service multicast resources that need to be pre-established currently, and the minimum threshold value of the number of idle service multicast resources, and then adjusting the number of idle service multicast resources in the SA accordingly, the requirement of a group subscribed in the SA on the service multicast resources can be met, and waste of service multicast resources due to excessive idle service multicast resources in the SA can be avoided.
In some embodiments, one possible implementation manner of S102 may be: and acquiring the second number according to the number of the groups signed in the SA, the number of the groups which do not meet the use condition of the multicast resources and the number of the groups distributed with the multicast resources.
In this embodiment, the number of groups subscribed in the SA may be the number of groups that need to use air interface resources in the SA.
And acquiring the number of the groups which do not meet the use condition of the multicast resources, wherein before acquiring the number of the groups which do not meet the use condition of the multicast resources, whether the groups can meet the use condition of the multicast mode resources or not needs to be judged. Optionally, first, the number of actually online users in each group, that is, the sixth number, is obtained; then judging whether the sixth number is greater than a preset threshold, and if the sixth number is greater than the preset threshold, determining that the group meets the use condition of multicast resources; and if the sixth number is less than or equal to the preset threshold, determining that the group does not meet the use condition of the multicast resources. For example, when the preset threshold is 100, if the sixth number in a group is 120, the group meets the multicast resource usage condition; if the sixth number in a group is 80 or 100, the group does not satisfy the multicast resource usage condition. And finally, counting the number of the groups which do not meet the use condition of the multicast resources.
The preset threshold may be determined by the number of users using the same MBSFN subframe resource as a service unicast resource and the number of groups using the same MBSFN subframe resource as a service multicast resource, for example: the preset threshold is equal to the number of the users divided by the number of the groups. For example: the number of groups using the same MBSFN subframe resource as a service multicast resource is 10, and the number of users using the same MBSFN subframe resource as a service unicast resource is 100, and the preset threshold is 10.
It should be noted that, when a group subscribed in the SA is released, if the service multicast resource usage condition is satisfied before the group is released, the group is released while being unbound from the used pre-established service multicast resource, and the state of the pre-established service multicast resource is set to be idle.
Optionally, if the group meets the multicast resource use condition, allocating a service multicast resource to the group, and setting the service multicast resource to be occupied by an idle resource; and if the group does not meet the use condition of the multicast resources, respectively allocating service unicast resources for each user in the group.
Whether the group meets the service multicast resource using condition is judged by comparing the number of the actual online users in the signed group in the SA, and when the number of the actual online users in the group changes, whether the group uses the service multicast mode or each user in the group uses the service unicast mode can be judged in real time. The method can avoid the problems that when the number of the actual online users of the group is small, the service multicast resources are occupied, and the number of the actual online users of the subsequently signed group is large, the service multicast resources cannot be used, and only the unicast resources can be used, so that the air interface bandwidth is greatly consumed, the utilization rate of the service multicast resources is reduced, and the multicast resources can be used by the group with a large number of the actual online users.
The number of the groups to which the multicast resources are allocated may be that, when the service multicast resources are pre-established for the first time in the SA, the pre-established service multicast resources are not allocated to the group subscribed in the SA, and therefore, the number of the groups to which the multicast resources are allocated is 0 at this time; or, after the control is performed by the service multicast resource control method in the embodiment of the present invention, the subscription group that satisfies the service multicast resource usage condition in the SA has already been allocated with the service multicast resource, so the number of groups to which the multicast resource has been allocated at this time is represented as the number of subscription groups to which the service multicast resource has been allocated before the change of the subscription group state in the SA.
And acquiring the second number after determining the number of groups signed in the SA, the number of groups which do not meet the use condition of the multicast resources and the number of groups which are distributed with the multicast resources. And subtracting the number of the groups which do not meet the use condition of the multicast resources from the number of the groups signed in the SA to obtain a first result, subtracting the number of the groups which are distributed with the multicast resources from the first result to obtain a second result, and multiplying the second result by a preset ratio 2 to obtain a second number. The calculation formula is as follows: the second number (the number of groups subscribed within the SA-the number of groups that do not satisfy the multicast resource use condition-the number of groups to which multicast resources have been allocated) x a preset ratio 2, and the second number is obtained. The value of the preset ratio 2 may be the same as or different from the value of the preset ratio 1, and the value of the preset ratio 2 is the same as the value of the ratio 1, which is not described herein again.
In some embodiments, one possible implementation manner of S103 may be: and determining whether to delete the pre-established and currently idle service multicast resources or to increase the idle service multicast resources according to the first number, the second number and the third number.
In this embodiment, the explanations of the first number, the second number, and the third number are as described above, and are not repeated here.
In this embodiment, the rule for determining whether to delete the idle service multicast resource or add the idle service multicast resource may be:
when the first number is larger than the maximum value of the second number and the third number, determining the number of idle service multicast resources needing to be deleted currently as a fourth number according to the first number, the second number and the third number; and then deleting the idle service multicast resources according to the fourth number.
Optionally, the fourth number is obtained by subtracting the maximum value of the second number and the third number from the first number. The calculation formula for obtaining the fourth number is: the fourth number is the first number-max (second number, third number). For example, if the first number is 50, the second number is 20, and the third number is 30, since 50 is greater than the maximum value 30 of 20 and 30, it indicates that the service multicast resources pre-established in the SA and currently idle need to be deleted, and the deleted number is 20.
And starting a timer when the idle service multicast resources are deleted according to the fourth number, and deleting the idle service multicast resources according to the fourth number if the first number is still greater than the maximum value of the second number and the third number after the timer is overtime.
When the first number is smaller than the minimum value of the second number and the third number, determining the number of the current multicast resources of the services needing to be pre-established as a fifth number according to the first number and the second number; and increasing the pre-established idle service multicast resources according to the fifth number.
Optionally, the fifth number is obtained by subtracting the first number from the second number. The calculation formula for obtaining the fifth number is as follows: the fifth number is the second number-the first number. For example, if the first number is 30, the second number is 80, and the third number is 90, since 30 is smaller than the minimum value 80 of 80 and 90, it is indicated that the pre-established service multicast resource in the SA needs to be increased, and the increased number is 20.
And when the pre-established idle service multicast resources are added according to the fifth number, if the timer in the SA is in an open state, closing the timer.
And when the first number is less than or equal to the maximum value of the second number and the third number, or the first number is greater than or equal to the minimum value of the second number and the third number, the idle service multicast resources are not deleted and increased. And if the timer is in the opening state at the moment, closing the timer.
In this embodiment, the number of service multicast resources that are pre-established and currently idle in the SA, the maximum number of service multicast resources that are currently required to be pre-established, the minimum threshold value of the number of idle service multicast resources, and the preset ratio are used to pre-establish the service multicast resources in the SA and control the number of service multicast resources in the SA. The idle service multicast resources in the SA can be ensured to meet the requirements of the subscribed group in the SA, and the problem that the group establishment delay cannot meet the specification of the protocol requirement due to the update period existing in the MCCH configuration change is solved.
