Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
For the convenience of the description of the following embodiments, a satellite communication system is described: the satellite communication system comprises satellite equipment, a ground station and terminal equipment, when one terminal equipment is communicated with the other terminal equipment through the satellite communication system, the terminal equipment is connected with the satellite equipment and sends data, and the satellite equipment sends the data sent by the terminal equipment to the other terminal equipment through the ground station. A schematic structural diagram of a system in which a terminal device is connected to a satellite device is shown in fig. 1, where the satellite device includes a communication processing module, and the communication processing module includes: a Core Network (GCN), a short message broadcasting center (CBC), a control center, a Gateway Controller (GSC), and a Gateway Transceiver Station (GTS).
Carriers are carriers for carrying signaling and communication services (such as voice, short message, and fax, etc.), and are classified into two categories according to their purposes: the system comprises a common carrier and a special carrier, wherein the common carrier is mainly used for carrying common information of the system, and the special carrier is mainly used for carrying special information related to a user. The dedicated carriers include the following three carriers: the system comprises a special control carrier, a voice service carrier and a data service carrier, wherein the special control carrier is specially used for accessing a radio resource control signaling, the voice service carrier is specially used for accessing a voice service, and the data service carrier is specially used for accessing a data service.
In the prior art, a terminal device sends an RRC (Radio Resource Control) connection request to a satellite device to request a signaling allocation Resource between the terminal device and the satellite device; specifically, the terminal device sends the RRC connection request to the GTS by using a common carrier, and the GTS transparently transmits the RRC connection request to the GSC after receiving the RRC connection request; if available dedicated control carrier exists, GSC selects one available dedicated control carrier, allocates resource for the signaling on the dedicated control carrier, then generates RRC connection establishment message according to the resource allocation information of the resource allocated for the signaling, and sends the RRC connection establishment message to the terminal equipment through the common carrier. If the available dedicated control carrier does not exist, the corresponding resource cannot be allocated to the signaling, so that the access of the terminal equipment fails. When a plurality of terminal devices requesting access exist, access failure often occurs, so the invention provides a resource allocation method to solve the problem of low success rate of accessing the terminal device to the network in the prior art.
One of the core ideas of the embodiment of the invention is that after receiving an RRC connection establishment request message sent by a terminal device, a satellite device allocates resources for a signaling between the terminal device and the satellite device on a voice service carrier when determining that no available special control carrier exists, so that the success rate of accessing the terminal device to a network is improved by increasing the carriers capable of bearing the signaling.
Referring to fig. 2, a flowchart illustrating steps of an embodiment of resource allocation according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, when the terminal equipment is connected with the satellite equipment, the RRC connection establishment request message can be sent to the satellite equipment to request the satellite equipment to allocate resources for the signaling between the terminal equipment and the satellite equipment, so that the RRC connection establishment request message comprises the resource occupation requirement of the signaling between the terminal equipment and the satellite equipment. After receiving the RRC connection establishment request message, the satellite device allocates network resources to the signaling according to a network resource usage condition in the satellite device, which is specifically as follows:
One of the important ideas of the embodiments of the present invention is to preferentially select a carrier carrying the signaling from dedicated control carriers, and if there is no dedicated control carrier available for carrying the signaling, select a carrier carrying the signaling from voice service carriers. Therefore, after receiving the RRC connection establishment request message, the satellite device determines for the first time whether a dedicated control carrier meeting the requirement of allocating the signaling occupied resource exists, and if the dedicated control carrier meeting the requirement of allocating the signaling occupied resource exists, step 203 is executed; if there is no dedicated control carrier satisfying the resource requirement for allocating the signaling occupancy, step 204 is executed.
When it is determined that there exists a dedicated control carrier that meets the requirement for allocating the signaling occupied resource, a dedicated control carrier may be selected according to a first preset rule, and then the selected dedicated control carrier is determined as a target carrier, where the preset rule may be set according to a requirement, for example, a dedicated control carrier that has a dedicated control channel to meet the requirement for allocating the signaling occupied resource is selected.
Step 204, searching a target carrier from the voice service carriers.
When determining that no special control carrier meeting the requirement of allocating the signaling occupied resource exists, the embodiment of the invention can find out the voice service carrier meeting the requirement of allocating the signaling occupied resource from the voice service carriers, then select one voice service carrier from the voice service carriers meeting the requirement of allocating the signaling occupied resource according to a second preset rule, and then determine the selected voice service carrier as a target carrier; the second preset rule is set according to requirements, such as selecting the voice service carrier with the least number of users to be carried, and the like. Wherein the target carrier is used for allocating resources for the signaling.
After the target carrier is determined, resources are distributed for the signaling in the target carrier, and if the target carrier is a voice service carrier, resources with the same number of occupied resource requirements are distributed for the signaling on the voice service carrier; and if the target carrier is a special control carrier, distributing a special control channel matched with the corresponding occupied resource requirement number for the signaling on the special control carrier. After allocating resources for the signaling, resource allocation information may be generated, where the resource allocation information is carrier information used for carrying signaling between the terminal device and the satellite device, such as xx Hz voice service carriers, and x-x slots of an xth subframe; and then generating an RRC connection establishment message according to the resource allocation information, and sending the RRC connection establishment message to terminal equipment through a common carrier. Therefore, the terminal equipment can determine that the RRC connection establishment message is a response message of the RRC connection establishment request message sent by the terminal according to the terminal identification in the RRC connection establishment message, and then establish communication with the satellite equipment by adopting a resource transmission signaling on a corresponding carrier according to the resource allocation information in the RRC connection establishment message, so as to access the network.
To sum up, the satellite device of the embodiment of the present invention receives a radio resource control RRC connection establishment request message sent by a terminal device, and then allocates resources to a signaling according to the request message including a resource occupation requirement of the signaling between the terminal device and the satellite device; in the process of allocating resources for the signaling, whether a special control carrier meeting the requirement of allocating the signaling occupied resources exists can be judged, if yes, the available special control carrier is determined to exist, and a target carrier can be searched from the special control carrier meeting the requirement of allocating the signaling occupied resources; if the carrier does not exist, namely the dedicated control carrier which is not available is determined, searching a target carrier from the voice service carrier; and then distributing resources for the signaling in the target carrier wave and generating corresponding resource distribution information, then generating RRC connection establishment information according to the resource distribution information, and sending the RRC connection establishment information to the terminal equipment, so that the terminal equipment can realize communication with the satellite equipment through the carrier wave bearing signaling corresponding to the RRC connection establishment information. When the available special control carrier is determined to exist, the target carrier capable of allocating resources for the signaling is selected from the available special control carrier, and when the available special control carrier is determined not to exist, the target carrier capable of allocating resources for the signaling is selected from the voice service carrier, so that the signaling can be borne by the special control carrier, the signaling can also be borne by the voice service carrier, the carrier capable of bearing the signaling is increased, and the success rate of access of the terminal equipment is improved.
In another embodiment of the present invention, when it is determined that there is no dedicated control carrier that satisfies the resource requirement for allocating the signaling occupancy, a target carrier may be searched for from a voice service carrier of an unaccessed user; if the target carrier is not found from the voice service carriers of the non-accessed users, the target carrier can be also found from each voice service carrier of the accessed users; correspondingly, the ways of searching for the target carrier from the voice service carriers of different non-accessed users and the voice service carriers of accessed users are different, and the specific ways are as follows:
referring to fig. 3, a flowchart illustrating steps of another embodiment of resource allocation of the present invention is shown.
Step 301, the satellite device receives a radio resource control RRC connection establishment request message sent by a terminal device, where the request message includes a resource requirement occupied by a signaling between the terminal device and the satellite device.
In the embodiment of the invention, the terminal equipment can realize various services such as voice call, fax, internet access and the like through the satellite communication network, and when any service is required to be carried out by the terminal equipment, the terminal equipment can be connected with the satellite equipment and then accessed into the satellite wireless network. Specifically, the terminal device may send a radio resource control RRC connection establishment request message to the satellite device to request the satellite device to allocate resources for signaling with the satellite device; the request message includes a signaling resource occupation requirement, where the signaling resource occupation requirement includes a number of signaling resource occupation requirements, and of course, the request message may also include other requirements such as a power requirement for carrying signaling, and the like.
After receiving the RRC connection establishment request message, the satellite device of the embodiment of the present invention may determine for the first time whether there is a dedicated control carrier that satisfies the requirement for allocating resources occupied by the signaling, and if there is a dedicated control carrier that satisfies the requirement for allocating resources occupied by the signaling, execute step 315. Since the voice service carrier has a higher requirement on the network performance than the data service carrier, in order to ensure the real-time performance of signaling transmission between the terminal device and the satellite device and reduce the waiting time for terminal device access, if there is no dedicated control carrier satisfying the resource requirement for allocating the signaling, a target carrier capable of carrying the signaling is selected from the voice service carriers, i.e., step 303 is executed.
The method for judging whether the dedicated control carrier meeting the resource requirement for allocating the signaling occupation exists specifically comprises the following steps: for each dedicated control carrier, judging whether an unoccupied channel type matched with the number of the resource requirements occupied by the signaling exists on the dedicated control carrier, and if the channel type matched with the number of the resource requirements occupied by the signaling exists on the dedicated control carrier, determining that the dedicated control carrier meets the requirement of allocating the signaling occupied resource; and if the special control carrier does not have a channel with the channel type matched with the number of the resources required to be occupied by the signaling, determining that the special control carrier does not meet the requirement for allocating the resources required to be occupied by the signaling.
In voice service carriers of the satellite equipment, users may be accessed to partial voice service carriers, users are not all accessed to the partial voice service carriers, the voice service carriers of all accessed users can be determined as the voice service carriers of the accessed users, and the voice service carriers of all not accessed users are determined as the voice service carriers of the not accessed users; generally, if a voice service carrier of a non-accessed user exists, searching a target carrier from the voice service carrier of the non-accessed user; and if the voice service carrier of the unaccessed user does not exist, or the target carrier is not found from the voice service carrier of the unaccessed user, searching the target carrier from the voice service carrier of the accessed user. The step of searching the target carrier from the voice service carrier of the non-access user is as follows:
the carrier meeting the requirement of allocating the signaling occupied resource can be searched from the voice service carriers of the unaccessed users, specifically, whether the voice service carrier of each unaccessed user meets the requirement of allocating the signaling occupied resource can be sequentially judged, that is, the number of continuous unoccupied resources (i.e. the number of slots) in the voice service carrier of the unaccessed user is judged for the voice service carrier of each unaccessed user, whether the number of the continuous unoccupied resources is not less than the number of the signaling occupied resource requirements is judged, and if so, the voice service carrier of the unaccessed user can be determined as the carrier meeting the requirement of allocating the signaling occupied resource; if not, the voice service carrier of the unaccessed user can be determined as the carrier which does not meet the resource requirement for distributing the signaling occupation, and then the voice service carrier of the next unaccessed user is judged.
Step 304, if the carrier meeting the resource requirement of the signaling occupation is found from the voice service carriers of the non-access users, selecting the carrier with the highest priority from the found carriers to determine as the target carrier.
If the carrier meeting the requirement of allocating the signaling occupied resource is found from the voice service carriers of the non-access user, the priority of each carrier meeting the requirement of allocating the signaling occupied resource can be determined according to a third preset rule, wherein the third preset rule can be set according to the requirement. For example, if the priority of a voice service carrier is set in advance according to the frequency points of the voice service carrier, the frequency points of the carriers meeting the requirement of allocating the signaling occupied resource may be determined first, and then the priority of the carriers meeting the requirement of allocating the signaling occupied resource may be determined according to the frequency points of the carriers meeting the requirement of allocating the signaling occupied resource. For another example, if the priority is determined in advance according to the number of users accessing to the voice service carrier, the number of users accessing to the carriers meeting the requirement of allocating the signaling occupied resource is determined first, and then the priority of the carriers meeting the requirement of allocating the signaling occupied resource is determined according to the number of users. After determining the priority of each carrier meeting the requirement of allocating the signaling occupied resource, the carriers meeting the requirement of allocating the signaling occupied resource can be sorted in an ascending order and a descending order, and then the carrier with the highest priority meeting the requirement of allocating the signaling occupied resource is determined as a target carrier.
And 305, allocating unoccupied resources in the target carrier to the signaling.
Unoccupied resources in the target carrier may be allocated to the signaling.
Step 306, if no carrier meeting the requirement of allocating the signaling occupied resource is found from the voice service carriers of the un-accessed user, finding the carrier meeting the requirement of allocating the signaling occupied resource from each voice service carrier of the accessed user allowed to be preempted.
In the embodiment of the invention, the users accessed to the voice service carrier of the accessed user comprise the users allowed to be preempted and the users not allowed to be preempted, if the users accessed to the voice service carrier of the user comprise the users allowed to be preempted, the voice service carrier is determined as the voice service carrier of the users allowed to be preempted; if the user accessing the voice service carrier of the user does not include the user allowed to be seized, determining the voice service carrier as the voice service carrier which is accessed to the user not allowed to be seized; the user allowed to be preempted is a user allowed to be preempted by occupying resources, and whether the user is allowed to be preempted can be judged according to the Mobile Directory Number (MDN) corresponding to the user, for example, the Number at the beginning of 181 is allowed to be preempted, and the Number at the beginning of 131 is not allowed to be preempted; and the priority of the user allowed to be preempted can be determined according to the MDN corresponding to the user allowed to be preempted. Therefore, if the carrier meeting the requirement of allocating the signaling occupied resource is not found from the voice service carriers of the un-accessed user, the carrier meeting the requirement of allocating the signaling occupied resource is found from each voice service carrier of the accessed user allowed to be preempted.
Judging whether each voice service carrier accessed to the user allowed to be preempted meets the requirement of allocating the signaling occupied resource, specifically comprising the following steps: for each voice service carrier accessed to the user allowed to be preempted, judging whether the number of resources occupied by the user allowed to be preempted on the carrier is not less than the number of resources occupied by the signaling, if so, determining that the carrier meets the requirement of allocating the signaling to occupy the resources, and if not, determining that the carrier does not meet the requirement of allocating the signaling to occupy the resources; and searching the carrier meeting the resource requirement occupied by the signaling from each voice service carrier accessed to the user allowed to be preempted.
If the carrier meeting the requirement of allocating the resources occupied by the signaling is found from the voice service carriers of the users allowed to be preempted, determining a target carrier according to the priority of the resources occupied by the users allowed to be preempted by each carrier, which is specifically as follows:
and 307, judging whether the priorities of the resources which are allowed to be occupied by the preempted users by all the carriers are the same.
In the embodiment of the invention, whether the priorities of the resources occupied by the user allowed to be preempted are the same on the voice service carriers of the user allowed to be preempted and accessed, which all meet the requirement of allocating the signaling occupied resources, can be judged, wherein the priority of the resources occupied by the user allowed to be preempted is the same as the priority of the user allowed to be preempted. If the priorities of all the resources allowed to be occupied by the preempted users on all the carriers are not the same, sequencing the users allowed to be occupied according to the priorities of the resources allowed to be occupied by the preempted users, and then executing step 308; if all the priorities of the resources allowed to be occupied by the preempted user on all the carriers are the same, step 309 is executed.
Step 308, determining the user with the lowest resource priority allowed to be occupied by the preempted user as a target user; and determining the carrier corresponding to the target user as the target carrier.
If the priorities of all the resources allowed to be occupied by the preempted users on all the carriers are not the same, determining the user with the lowest priority of the resources allowed to be occupied by the preempted users as a target user, and determining the carrier corresponding to the target user as a target carrier.
If the priorities of all resources occupied by the allowed preempted users on all carriers are the same, determining a target carrier according to the number of the resources correspondingly occupied by each allowed preempted user; the method comprises the following specific steps:
And step 310, determining the allowed preempted user corresponding to the minimum difference value as a target user.
In the embodiment of the invention, the difference value between the number of resources occupied by each user allowed to be preempted and the number of resources required to be occupied by the signaling can be calculated, and then the target user is determined according to the difference value; in order to save resources, the user allowed to be preempted corresponding to the minimum difference value may be determined as a target user, and then the carrier corresponding to the target user may be determined as a target carrier. For example, if the number of resources occupied by the signaling is 4, and the calculated difference includes 0, 2, and 4, the user allowed to be preempted, which has a difference of 0 from the number of resources occupied by the signaling, is determined as the target user, that is, the user with the number of resources occupied by 4 is determined as the target user.
And step 312, releasing the resources correspondingly occupied by the target user.
After a target user is determined, resources occupied by the target user correspondingly can be released, wherein the modes for releasing the resources of the target user are various, such as reducing the speed, namely reducing the data transmission rate corresponding to the voice service, for example, reducing the speed from 4k to 2.4 k; such as the cell accessed by the switching terminal equipment, the release of the radio access bearer, the radio connection of the direct terminal target user, and the like.
In the process of releasing the resources by the target user, the resources on the dedicated control carrier may also be released, so that it can be determined again whether there is a dedicated control carrier that meets the requirement of allocating the resources occupied by the signaling, and if there is a dedicated control carrier that meets the requirement of allocating the resources occupied by the signaling, step 315 is executed; if there is no dedicated control carrier satisfying the resource requirement for allocating the signaling occupancy, step 314 is executed.
In addition, in another embodiment of the present invention, the satellite device starts to search for a target carrier from a voice service carrier until before allocating resources for the signaling in the target carrier; when detecting that the resource is released, judging whether a special control carrier meeting the requirement of distributing the signaling occupied resource exists, if so, stopping the current operation, and searching a target carrier from the special control carrier meeting the requirement of distributing the signaling occupied resource; if not, continuing to execute the current operation.
Step 314, allocating the released resources in the target carrier to the signaling.
And after determining that the dedicated control carrier which meets the resource requirement information of the signaling does not exist, allocating the released resources in the target carrier to the signaling.
If the special control carrier meeting the requirement of distributing the signaling occupied resource exists, selecting a target carrier from the special control carriers meeting the requirement of distributing the signaling occupied resource according to a first preset rule; and then determining a channel matched with the number of the resource requirements occupied by the signaling in the target carrier, and allocating the channel to the signaling.
Step 317, generating resource allocation information, and generating and sending an RRC connection establishment message to the terminal device according to the resource allocation information.
After the signaling is allocated with resources in the target carrier, corresponding resource allocation information can be generated, then an RRC connection establishment message is generated according to the resource allocation information, and the RRC connection establishment message is sent to the terminal equipment through the common carrier. So that the terminal device can access the network according to the resource allocation information in the RRC connection setup message.
In another embodiment of the present invention, if all the dedicated control carriers satisfying the requirement for allocating resources occupied by the signaling fail to allocate resources to the signaling, step 303 can be executed. If the target carrier is the voice service carrier of the unaccessed user, when the voice service carrier with the highest priority fails to allocate resources to the signaling, the voice service carrier with the secondary priority is determined as the target carrier to realize the allocation of resources to the signaling, and so on.
It should be noted that, in the embodiment of the present invention, when searching for a resource that meets the requirement number matching of the resource occupied by the signaling from a voice service carrier of an unaccessed user, the searched resource is a continuous resource; correspondingly, the resources allocated for the signaling are also continuous resources.
In the embodiment of the invention, when a special control carrier meeting the requirement of distributing the signaling occupied resource does not exist, the target carrier is selected from the voice service carriers, and the requirement of the voice service carriers on the network performance is higher, so that the real-time performance of signaling transmission is ensured.
