Description
Technical Field
The present invention relates to the field of communications, and in particular, to a resource maintenance method and apparatus.
Background
In a satellite communication system, a control center manages, plans and controls system resources such as beams, frequencies, time slots, power and the like uniformly, and the use of the resources by Gateway Stations (GS) must be subject to the management of the control center.
The operation and control center allocates resources for the gateway station by two modes of pre-allocation and real-time allocation (also called on-demand allocation). After the user service is accessed to the gateway station, when the pre-allocated resources can not meet the requirements of the user service, the gateway station applies for real-time allocation of the resources to the operation and control center. In the process of allocating resources in advance and/or in real time, if the gateway station does not establish the resources allocated by the operation and control center, such as carriers or channels, the gateway station establishes the resources. After the user service is over, the gateway station releases the service user, if the user service is the last user service on the resource, the gateway station also releases the resource. And subsequently, if the resource allocated to the gateway station by the operation control center is the resource which is subjected to the establishing and releasing processes before the gateway station, the gateway station can initiate the establishing and releasing processes of the resource again.
In summary, in the scenario of resource allocation for user services, the same allocated resource is repeatedly established and released, which results in large signaling overhead and prolonged user service access.

Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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 technical scheme provided by the embodiment of the invention is used for solving the problems of large signaling overhead and prolonged user service access caused by repeated establishment and release of the same allocated resource under the scene of allocating the resource for the user service. Taking a scenario that an operation control center in a satellite communication system allocates resources for user services accessed in a gateway station as an example, the satellite communication system is a microwave communication system which uses a satellite as a relay station to forward microwave signals, and the satellite communication system comprises a satellite network, a ground network and users. In order to fully utilize resources in the satellite system and guarantee efficient operation of the satellite communication system, an operation control center manages and controls the resources in the satellite system, and allocates the resources to the gateway station in two modes of pre-allocation and real-time allocation, wherein the resources comprise resources such as beams, frequencies, time slots, power and the like. In order to solve the problems of large signaling overhead and prolonged user service access caused by repeated establishment and release of the same allocated resource in a scene of allocating resources to a user service, embodiments of the present invention provide a resource maintenance method and apparatus.
The technical scheme provided by the embodiment of the invention relates to a gateway station. A gateway station may be referred to by different names in different communication systems, referred to as a gateway station in a satellite communication system, and referred to as a radio network controller in a wireless communication system. The gateway station in the satellite communication system is a device deployed in a ground network, is a bridge connecting the satellite network and the ground network, and has the functions of routing, packet forwarding, protocol conversion, mobility management, connection control, resource allocation and the like. As shown in fig. 1, the Gateway Station includes a Gateway Station Controller (GSC) and a Gateway Transceiver Station (GTS), and the operation and control center is connected to the Gateway Station through an O2 interface.
The technical scheme provided by the embodiment of the invention relates to an operation control center. In a satellite communication system, an operation control center is a server for managing and controlling resources, and the operation control center has functions of mobility management, call processing, link management and handover mechanisms.
The following detailed description of various embodiments of the invention refers to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present invention only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
The first embodiment is as follows:
as shown in fig. 2, an embodiment of the present invention provides a resource maintenance method, where the method includes:
step 201: after a first preset time length taking the ending time of the user service as the starting time, the gateway station judges whether other user services except the user service are accessed to the resources accessed by the user service.
When a user service request is accessed to a gateway station, the gateway station allocates resources for the user service according to the requirement of the user service, wherein the resources are allocated by an operation control center, and can be allocated in advance by the operation control center or can be allocated by the operation control center in real time. In general, if the resource pre-allocated to the gateway station cannot meet the requirement of the user service, the gateway station applies for real-time allocation of the resource to the operation and control center, where the resource may be a carrier resource including a channel.
When the user service is finished, the gateway station releases the user service, if the user service is the last user service on the resource accessed by the user service, the gateway station in this embodiment does not immediately release the resource, and after the gateway station reserves the resource for a period of time, the gateway station determines whether the resource needs to be released by judging whether other user services except the user service are accessed on the resource, so as to avoid the problem of repeated establishment and release of the same resource caused by the operation and control center distributing the resource for the gateway station again after the gateway station releases the resource. In this embodiment, a period of time for retaining the user service after the user service is ended is represented as a first preset time, and a starting time of the first preset time is an ending time of the user service.
In this embodiment, the gateway station may determine that the first preset time duration passes through by using a cycle timer, where the method is as follows:
the method comprises the following steps: when the user service is finished, the gateway station starts a cycle timer for the resource accessed by the user service, and sets the timing time and the overtime times of the cycle timer, wherein the starting time of the cycle timer is the finishing time of the user service.
The time timed by the cycle timer is the set time, at this time, the first preset time length is equal to the product of the time length and the overtime frequency, of course, according to the actual requirement, the time timed by the cycle timer at each time may also be different, and at this time, the first preset time length is equal to the sum of the time timed at each time. The timing time and the number of times of timeout of the cycle timer may be set in advance, or may be set when the cycle timer is started. The number of times of timeout refers to the number of times the cycle timer is allowed to exceed the timing time.
Step two: and when the actual overtime times of the cycle timer reach the set overtime times, the gateway station determines that the first preset time length passes.
The actual number of times of timeout is the actual number of times the loop timer exceeds the timing time, and the initial value of the actual number of times of timeout is 0. When the circulation timer is started and a timing time is passed, the circulation timer resets the timing time and re-times, at the moment, the actual overtime times are added by one by the circulation timer, and the like, until the actual overtime times of the circulation timer reach the set overtime times, the circulation timer stops timing, and at the moment, the gateway station determines that a first preset time period is passed.
It should be noted that, in the method for determining that the first preset time period passes by the gateway station in the embodiment of the present invention, in addition to determining that the first preset time period passes by the cycle timer, other methods may also be used to determine that the first preset time period passes by. For example, when the user service is ended, the gateway station starts a timer for the resource accessed by the user service, and sets the timing time equal to a first preset time length. After the timer finishes timing, the gateway station determines that the first preset time length passes because the timing time of the timer is equal to the first preset time length.
In this embodiment, before step 201, the following steps may be further included:
when the user service is finished, the gateway station releases the user service, and the gateway station judges whether other user services except the user service are accessed to the resources accessed by the user service within a second preset time length taking the finishing time of the user service as the starting time, wherein the second preset time length is less than or equal to the first preset time length. If it is determined that other user services except the user service are accessed on the resource accessed by the user service, the gateway station determines that the resource does not need to be released, and does not execute step 201 and step 202. If it is determined that no other user service except the user service is accessed on the resource accessed by the user service, the steps 201 and 202 are continuously executed. Because the second preset time is less than or equal to the first preset time, the method optimizes the step 201 and the step 202, avoids the problems of large signaling overhead and prolonged user service access caused by repeated establishment and release of the same allocated resource in the scene of user service resource allocation, reduces the signaling overhead and shortens the time delay of user service access.
The following describes the process of implementing the above method by a cycle timer:
when the user service is finished, the gateway station starts a cycle timer for the resource accessed by the user service, and sets the timing time and the overtime times of the cycle timer, wherein the starting time of the cycle timer is the finishing time of the user service.
The gateway station can be determined to pass through a first preset time and a second preset time by the same cycle timer, and the starting time of the first preset time and the starting time of the second preset time are both the ending time of the user service. The second preset time length is equal to the time timed by the cycle timer for the first time. The time timed by the cycle timer every time can be set to be the set timed time, and at the moment, the first preset duration is equal to the product of the timed time and the overtime times. According to actual requirements, the time of each time of the cycle timer can also be different, and at this time, the first preset time length is equal to the sum of the time of each time.
When the cycle timer is started and the first time is passed, the gateway station judges whether the user service is accessed on the resource accessed by the user service or not. If it is determined that other user services except the user service are accessed on the resource accessed by the user service, the gateway station determines that the resource does not need to be released, deletes the cycle timer, and does not execute step 201 and step 202; if it is determined that no other user service except the user service is accessed on the resource accessed by the user service, the cycle timer resets the timing time and re-times, the cycle timer adds one to the actual timeout number, and the gateway station continues to execute step 201 and step 202.
It should be noted that, in the method for determining that the second preset time period passes by the gateway station in the embodiment of the present invention, in addition to determining that the second preset time period passes by the cycle timer, other methods may also be used to determine that the second preset time period passes by. For example, when a user service is ended, the gateway station starts two timers for resources accessed by the user service respectively, and sets the timing times of the two timers respectively, wherein the starting times of the first preset time and the second preset time are the ending times of the user service. The timing time of one timer is set to be equal to a second preset time length, the timing time of the other timer is set to be equal to a first preset time length, and the second preset time length is smaller than the first preset time length. And after the timer with the timing time equal to the second preset time length is timed, the gateway station determines that the second preset time length passes because the timing time of the timer is equal to the second preset time length. In addition, according to actual requirements, the same timer can be used for determining the second preset time and the first preset time, and the second preset time is shorter than the first preset time. For example, when the user service is ended, the gateway station starts a timer for the resource accessed by the user service, and sets the timing time as a second preset duration, where the starting time of the timer is the ending time of the user service. When the timer is over, the gateway station determines that a second preset time period is passed. At the moment, the timer is reset and re-timed, the timing time is set to be the difference value between the first preset time length and the second preset time length, and when the timing of the timer is finished, the gateway station determines that the first preset time length passes.
Step 202: and the gateway station determines whether to release the resources according to the judgment result.
And after the gateway station determines that the first preset time duration passes, the gateway station judges whether other user services except the user service are accessed on the resources accessed by the user service. And the gateway station determines whether to release the resource according to the judgment result.
The resources accessed by the user service may be different types of resources, and the types of the resources include, but are not limited to, carrier resources including a Packet Data Channel (PDCH) and carrier resources including a Dedicated Channel (DCH). The carrier resources including the PDCH are used to establish a data service, and the carrier resources including the DCH are used to establish a voice service.
In the following, taking the resources accessed by the user service as carrier resources including PDCH or carrier resources including DCH as an example, respectively, the process of determining whether to release the resources accessed by the user service according to the determination result by the gateway station is as follows:
the first condition is as follows:
when the resources accessed by the user services are carrier resources containing PDCH, the gateway station judges whether other user services except the user services are accessed on the PDCH accessed by the user services after a first preset time length.
And if the user services except the user service are accessed on the PDCH accessed by the user service, the gateway station determines that the PDCH does not need to be released.
If the user service is judged not to be accessed on the PDCH accessed by the user service, the gateway station determines to release the PDCH, and at the moment, the gateway station initiates a cell reconfiguration process released by the PDCH to the base station.
When the gateway station determines to release the PDCH, since the PDCH is included in the PDCH carrier resources, it needs to further determine whether there is access to user services other than the user service on the carrier resources including the PDCH.
And if the gateway station judges that other user services except the user service are accessed on the carrier resources containing the PDCH, the gateway station determines that the carrier resources do not need to be released. If the carrier wave resource containing the PDCH is judged that other user services except the user service are not accessed, the gateway station determines to release the carrier wave resource, and at the moment, the gateway station initiates a cell reconfiguration process of releasing the carrier wave resource to the base station.
Case two:
when the resource accessed by the user service is the carrier resource containing the DCH, the gateway station judges whether other user services except the user service are accessed on the carrier resource containing the DCH accessed by the user service after the first preset time length.
If it is determined that other user services except the user service are accessed on the carrier resources including the DCH accessed by the user service, the gateway station determines that the carrier resources including the DCH do not need to be released. If the gateway station does not access other user services except the user service on the carrier resources which are accessed by the user service and contain the DCH, the gateway station determines to release the carrier resources which contain the DCH, and at the moment, the gateway station initiates a cell reconfiguration process of releasing the carrier resources which contain the DCH to the base station.
To illustrate
Taking the resource accessed by the user service as the carrier resource containing the PDCH as an example, as shown in fig. 3, the method includes the process of establishing and releasing the carrier resource containing the PDCH by the gateway station. After the gateway station obtains the carrier resource containing the PDCH from the operation and control center, the gateway station judges whether the carrier resource is established. If the carrier resource is not established, the gateway station initiates a cell reconfiguration process for establishing the carrier resource; if the carrier resource is determined to be established, the gateway station needs to determine whether a PDCH contained in the carrier resource is established, and if the PDCH is not determined to be not established, the gateway station establishes a cell reconfiguration process for initiating the PDCH. The resource release process shown in fig. 3 can refer to the contents of the above embodiments, and is not described here again.
By way of example, 2
Taking the resource accessed by the user service as the carrier resource containing the DCH as an example, as shown in fig. 4, the method includes the process of establishing and releasing the carrier resource containing the DCH by the gateway station. After acquiring the carrier resource containing DCH from the operation control center, the gateway station judges whether the carrier resource is established in the gateway station. If the carrier resource is not established, the gateway station initiates a cell reconfiguration process for establishing the carrier resource; if the carrier resource is determined to be established, the gateway station needs to determine whether the time slot state in the resource information of the carrier resource is activated, and if the time slot state in the resource information of the carrier resource is not activated, the gateway station updates the information of the carrier resource. The resource information of the carrier resource carries a resource allocation response message sent by the operation and control center to the gateway station. The resource release process shown in fig. 4 can refer to the contents of the above embodiments, and is not described here again.
In the first and second examples of this embodiment, in the process that the gateway station acquires the resource from the operation control center, the resource allocation response message sent by the operation control center to the gateway station carries information of the resource allocated by the operation control center to the gateway station, where the information of the resource may include information of an access frequency point, a channel type, a channel state, an initial time slot, a time slot state, a bandwidth, a direction, and the like of the resource.
In the resource maintenance method provided in the embodiment of the present invention, after a first preset time duration that takes an ending time of a user service as an initial time, a gateway station determines whether other user services except the user service are accessed to a resource accessed to the user service, and determines whether to release the resource according to a determination result. When the user service is finished, even if other user services except the user service are not accessed on the resources accessed by the user service, the gateway station does not immediately release the resources, and after the gateway station reserves the resources for a period of time, whether the resources need to be released is determined by judging whether other user services except the user service are accessed on the resources accessed by the user service, so that the problems that the signaling cost is large and the user service is prolonged when the same allocated resources are repeatedly established and released in a scene of user service resource allocation are avoided, the signaling cost is reduced, and the user service delay is shortened.
