The technical solution in the embodiment of the present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention. The invention is described in a clear and complete manner, and it is obvious that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

 As shown in FIG. 1 , an embodiment of the present invention provides a method for managing hardware resources of a communication board, including:

 101. Receive multiple resource scheduling requests initiated by a signaling processing process of multiple communication systems. The signaling processing process of the multiple communication systems may be, for example, a GSM signaling processing process, a UMTS signaling processing process, and an LTE signaling processing process.

 The resource scheduling request is used to request the use of the communication board hardware resources, and the communication board hardware resources may be hardware resources such as a CPU and a memory.

 102. The operation of the signaling processing process of the multiple communication systems is coordinated according to the multiple resource scheduling requests, so that the signaling processing processes of the multiple communication systems share the hardware resources of the communication board.

 In the embodiment of the present invention, the signaling processing process of the multiple communication systems may be shared by the signaling processing process of the multiple communication systems by scheduling the operation of the signaling processing process of the multiple communication systems according to the multiple resource scheduling requests. Hardware resources, thereby improving the utilization of base station hardware resources.

 Further, as described in FIG. la, in the foregoing step 102, according to the multiple resource scheduling requests, the operation of the signaling processing process for coordinating the multiple communication systems may be specifically implemented as follows:

 1021. Monitor the usage of hardware resources of the communication board.

 For example, you can monitor which resources in the hardware resources of the communication board are in the occupied state, which resources are in the idle state, and what is the usage rate of the hardware resources of the communication board.

 The usage of the hardware resources of the communication board may be the usage of the hardware resources of one communication board, or the usage of the hardware resources of multiple communication boards.

 1022. Unifiedly measure the hardware resources of the communication board and the resources required for the operation of the signaling processing process of various communication systems in a cross-standard and cross-hardware resource measurement unit.

The resource measurement unit includes millions of instructions MIPS, signaling elements, or messages per second. The signaling element may be a piece of message signaling in the air interface interaction process. For example, when the resource measurement unit is represented by MIPS, the maximum number of resources supported by the communication board hardware resources may be represented as 2000 MIPS, and the LTE signaling processing process needs to occupy 41 MIPS for 1CAPS (call access times per second).

 For example, if the resource measurement unit uses the signaling element, if the communication board hardware resource can process up to 500 signaling elements, the LTE signaling processing process needs to use 40 signaling elements corresponding to the communication board resource for processing one 1CAPS. .

 If the resource measurement unit uses the number of messages, if the communication board hardware resource can process up to 300 messages, the LTE signaling processing process 1CAPS needs to use the communication board resources corresponding to 10 messages.

 1023. When it is detected that the idle communication board hardware resource meets the resources required for the signaling processing process of the communication standard corresponding to the current resource scheduling request, the idle communication board hardware resource is scheduled, and the communication corresponding to the current resource scheduling request is started. The standard signaling processing process.

 For example, if the signaling processing process of LTE is to process 10CAPS, it is required to use 10*41 MIPS hardware resources. If the idle communication board hardware resources can reach 10*41 MIPS, the idle communication board hardware is scheduled. The resource, and the signaling processing process of the LTE is started, so that the signaling processing process of the LTE can use the 10*41 MIPS idle communication board hardware resources.

 Further, as shown in FIG. 1b, the foregoing method further includes:

 103. When the hardware resource usage rate of the communication board reaches or exceeds the first preset threshold, the signaling of one or more communication systems in the multiple communication systems is flow-controlled.

 The first preset threshold may be 80%.

 For example, when the CPU usage of the communication board reaches or exceeds 80%, the signaling of one or more communication systems in the plurality of communication systems is flow-controlled.

 The flow control of the signaling of one or more communication systems in the multiple communication systems is implemented as follows: when the signaling processing process of one or more communication systems in the multiple communication systems is occupied by When the hardware resource meets or exceeds the resource configuration threshold of the communication system, the signaling of the communication standard is flow-controlled until the hardware resource occupancy rate converges within the first preset threshold.

For example, the resource allocation threshold of LTE can be set to 80 (CAPS) *41 (MIPS), also That is, the signaling processing process of the LTE can process up to 80 CAPS. When the CAPS processed by the LTE signaling processing process reaches or exceeds 80, the LTE signaling is flow-controlled, for example, the signaling under LTE is no longer received. Until the hardware resource occupancy rate converges to 80%.

 It should be noted that if the hardware resources occupied by the signaling processing process of one or more communication systems in the multiple communication systems do not meet or exceed the resource configuration threshold of the communication standard, the communication is not required. The standard signaling is used for flow control.

 Further, as shown in FIG. 1b, the foregoing method further includes:

 104. When the hardware resource usage rate of the communication board reaches or exceeds the second preset threshold, the signaling of all communication systems is flow-controlled until the hardware resource occupancy rate converges within the second preset threshold.

 The first preset threshold may be 90%.

 For example, when the CPU usage of the communication board reaches or exceeds 90%, the signaling of all communication systems is flow-controlled until the hardware resource occupancy rate converges to 90%. In an implementation manner of the embodiment of the present invention, the resources occupied by the signaling processing process of each communication system include a control plane resource and a user plane resource, and the control plane resource and the user plane resource are allocated according to a preset ratio. Resources, the method further includes:

 Monitoring the use of the control plane resources, releasing idle control plane resources to the user plane; and/or

 The usage of the user plane resource is monitored, and the idle user plane resource is released to the control plane for use.

 For example, the hardware resources of a communication board are taken as an example. As shown in Figure 2, all the blank boxes indicate the resources of the communication board. The resources indicated by each blank box may be dynamically occupied by the control plane or the user plane. .

When monitoring the usage of the control plane resource (that is, the resource occupied by the control plane), if the idle control plane resource is detected, the idle control plane resource may be released to the user plane for use; likewise, the user plane is monitored. When the usage of the resource (that is, the resource occupied by the user plane) is detected, if the idle user plane resource is detected, the idle user plane resource may be released to the control plane for use.

The module shares the hardware resources of the communication board. As shown in Figure 3a, the communication board further includes:

 a monitoring module 33, configured to monitor usage of hardware resources of the communication board;

 For example, you can monitor which resources in the hardware resources of the communication board are in the occupied state, which resources are in the idle state, and what is the usage rate of the hardware resources of the communication board.

 The usage of the hardware resources of the communication board may be the usage of the hardware resources of one communication board, or the usage of the hardware resources of multiple communication boards.

 The control module 32 is specifically configured to uniformly measure the resources of the communication board and the resources required for the operation of the signaling processing process of various communication standards in a cross-standard and cross-hardware resource measurement unit;

The L3 signaling processing module of the LTE needs to occupy the communication board resources of the Z1 MIPS for processing one unit of the CAPS, then the GSM, UMTS and The proportion of the communication board resources occupied by the respective L3 signaling processing modules of LTE is XI: Yl: Zl.

 It can be understood that, if the L3 signaling processing module of the GSM, UMTS, and LTE needs to be processed in a shared granularity of M units, the basic shared unit number of the communication board resources is GSM, UMTS. The L3 signaling processing module of the LTE and the LTE need to occupy M times of the basic shared unit number of the communication board resources when processing in a shared granularity of 1 unit.

 For example, when the GSM L3 signaling processing module needs to transmit 6 carriers, the GSM L3 signaling processing module occupies 6 X MIPS of the communication board resources.

 As shown in FIG. 7, in another embodiment of the present invention, the at least two communication system processing modules include: an L2 user plane processing module of a first communication system, and an L2 user plane processing module of a second communication system. ...the L2 user plane processing module of the i-th communication system.

 For example, the GSM, UMTS, and LTE communication systems are used as examples. When configuring a communication board, the L2 user plane processing module of GSM, the L2 user plane processing module of UMTS, and the L2 user plane processing module of LTE can be used. Deployed on a communication board.

 Correspondingly, the proportion of resources occupied by the respective L2 user plane processing modules of the GSM, UMTS, and LTE when sharing the resources of the communication board is as follows:

When the L2 user plane processing module of GSM adopts the carrier as the shared granularity, the L2 user plane processing module of the UMTS adopts the cell as the shared granularity, and the L2 user plane processing module of the LTE adopts the cell as the shared granularity, and the basic shared unit adopts the MIPS, if the GSM The L2 user plane processing module needs to occupy X2 MIPS communication board resources when transmitting one carrier. The L2 user plane processing module of UMTS needs to occupy Y2 MIPS communication board resources when serving one cell, and L2 user plane processing of LTE When the module provides services for 1 cell, it needs to occupy Z2 MIPS communication board resources, so the L2 users of GSM, UMTS and LTE are everywhere. The ratio of the management module occupying the communication board resources is X2: Y2: Z2.

 As shown in FIG. 8, in another embodiment of the present invention, the at least two communication system processing modules include: a transmission user plane processing module of a first communication system, and a transmission user plane processing module of a second communication system. ...the transmission user plane processing module of the i-th communication system,

 For example, the GSM, UMTS, and LTE communication systems are used as examples. When configuring a communication board, the GSM transmission user plane processing module, the UMTS transmission user plane processing module, and the LTE transmission user plane processing module may be used. Deployed on a communication board.

 Correspondingly, the proportion of resources occupied by the respective user plane processing modules of the GSM, UMTS, and LTE when sharing the resources of the communication board is as follows:

 When GSM uses the base station as the shared granularity, UMTS uses the base station as the shared granularity, LTE uses the base station as the shared granularity, and when the basic shared unit adopts MIPS, if the GSM transmission user plane processing module serves a base station, it needs to occupy X3 MIPS communication orders. The UMTS transmission user plane processing module needs to occupy Y3 MIPS communication board resources when serving one base station. The LTE transmission user plane processing module needs to occupy Z3 MIPS communication boards when serving one base station. Resources, then the ratio of each of the GSM, UMTS, and LTE transmission user plane processing modules occupying communication board resources is X3: Y3: Z3.

 It should be noted that the sharing granularity used by the at least two communication system processing modules when sharing the resources of the communication board may be the same or different. That is, the first sharing granularity and the second sharing granularity may be different from each other, or may be the same, partially different, and partially different. See Figure 2 - Figure 4 above for a description of shared granularity.

 In an implementation manner of the embodiment of the present invention, the resource of the communication board is a processor core.

 In the communication board shown in FIG. 5, when the i-th communication system processing module processes the i-th shared granularity of one unit, the resources of the Ni basic shared units of the communication board are occupied. When the i-th communication system processing module processes the i-th shared granularity of one unit, the performance of Ni basic shared units in the processor core of the communication board is occupied.

For example, if the processor core can handle up to 100 MIPS, then GSM L3 The signaling processing module needs to occupy 20 MIPS of communication board resources when transmitting one carrier. It means that the GSM L3 signaling processing module needs to consume 20 MIPS of processor core when transmitting one carrier.

 It can be understood that if the basic shared unit uses the signaling element, if the processor core can process up to 50,000 signaling elements, the L3 signaling processing module of the GSM needs to use a communication board of 400 signaling elements for transmitting one carrier. The resource refers to the performance of the GSM L3 signaling processing module transmitting a carrier and consuming the processor core to process 400 signaling elements.

 Similarly, if the basic shared unit adopts the number of messages, if the processor core can process up to 7000 messages, then the GSM L3 signaling processing module needs to use 800 signaling elements of communication board resources for transmitting one carrier, which means GSM. The L3 signaling processing module transmitting a carrier consumes the performance of the processor core processing 800 messages.

 In an implementation manner of the embodiment of the present invention, the number of shared granularities actually supported by the at least two communication system processing modules when sharing the resources of the communication board meets the following sharing formula:

 Pl/Ql+ p2/Q2+ ... +pi/ Q3≤ 100%;

 Wherein, pi is the number of units of the first type of shared granularity actually supported by the first communication system processing module, and Q1 is the first type of the communication system processing module when the communication board is only provided. The maximum number of units of the first type of shared granularity supported by the communication system processing module, p2 is the number of units of the second type of shared granularity actually supported by the second type of communication processing module, and Q2 is only the set of the communication board. In the second communication system processing module, the maximum number of units of the second type of shared granularity supported by the second communication system processing module, pi is the i-th shared granularity actually supported by the i-th communication system processing module. The number of units, Qi is the maximum number of units of the i-th shared granularity supported by the i-th communication system processing module when only the i-th communication system processing module is set for the communication board.

 Where pl ^ Ql , p2 ≤ Q2 , p3 ^ Q3.

In actual applications, if the number of shared granularities actually supported by a communication system processing module is configured to be larger, more communication board resources will be occupied. In order to avoid the configuration of the number of shared granularities actually supported by one or more communication system processing modules is too large, resulting in the certain or The sum of the resources required by the multiple communication system processing modules exceeds the number of resources that the communication board can provide. In actual implementation, the number of shared granularities actually supported by the various communication system processing modules set on each communication board can be adjusted. (For example, the manual adjustment may be performed by a technician, or other adjustment manners may be adopted, and the specific adjustment is not limited herein), so that the sharing granularity actually supported by each communication processing module when sharing the resources of the communication board can be satisfied. The sharing formula.

 For example, when the communication board is provided with the GSM L3 signaling processing module, the UMTS L3 signaling processing module, and the LTE L3 signaling processing module, if the GSM L3 signaling processing module uses the carrier as the shared granularity, the UMTS L3 The signaling processing module adopts CNBAP as the shared granularity, and the L3 signaling processing module of LTE adopts CAPS as the shared granularity, and the L3 signaling processing module of GSM, the L3 signaling processing module of UMTS, and the L3 signaling processing module of LTE actually support each. The number of shared granularities needs to satisfy al/Al + bl/B l + ... +cl/ CI ≤ 100%

 Where al is the number of carriers actually supported by the LTE L3 signaling processing module, and A1 is a carrier supported by the GSM L3 signaling processing module when the communication board only sets the GSM L3 signaling processing module. The maximum number, bl is the number of CNBAPs actually supported by the L3 signaling processing module of the UMTS, and B1 is the L3 signaling processing module of the UMTS when the communication board only sets the L3 signaling processing module of the UMTS. The maximum number of supported CNBAPs, cl is the number of CAPSs actually supported by the L3 signaling processing module of the LTE, and C1 is the L3 signaling of the UMTS when the communication board only sets the L3 signaling processing module of the LTE. The maximum number of CAPS supported by the processing module.

 Where al ^ Al , b l≤B l , c l≤C

For another example, the communication board is provided with a GSM L2 user plane processing module, a UMTS L2 user plane processing module, and an LTE L2 user plane processing module. If the GSM L2 user plane processing module uses the carrier as the shared granularity, the UMTS L2 user plane processing module uses the cell as the shared granularity, and the LTE L2 user plane processing module uses the cell as the shared granularity, then the GSM L2 user plane processing module, The number of shared granularities actually supported by the L2 user plane processing module of UMTS and the L2 user plane processing module of LTE needs to satisfy a2/A2+ b2/B2+ ... +c2l C2≤100%, Wherein, a2 is the number of carriers actually supported by the L2 user plane processing module of the GSM, and A2 is a carrier supported by the L2 user plane processing module of the GSM when the communication board only sets the L2 user plane processing module of the GSM. The maximum number, b2 is the number of cells actually supported by the L2 user plane processing module of the UMTS, and B2 is the L2 user plane processing module of the UMTS when the communication board only sets the L2 user plane processing module of the UMTS. The maximum number of cells, c2 is the number of cells actually supported by the L2 user plane processing module of the LTE, and C2 is the L2 user plane processing of the UMTS when the communication board only sets the L2 user plane processing module of the LTE The maximum number of cells supported by the module.

 Where a2 ^ A2 , b2 ≤ B2 , c2 ^ C2.
