In the embodiment of the invention, the initial live broadcast service strategy is determined according to the information of three dimensions of the region, the channel and the user. The following describes the process of the present invention with reference to specific examples.
In the embodiment of the invention, the live broadcast business strategy comprises a primary service strategy, a secondary service strategy and a tertiary service strategy. The primary service strategy, the secondary service strategy and the tertiary service strategy are formed by initial calculation decisions of the system and are initial live broadcast service strategies in a default state of the system, and then dynamic adjustment can be implemented according to a service state, a link state, channel information and the like in the live broadcast service process.
In specific implementation, the primary service policy is used to determine the availability of a live broadcast service system and the availability of a live broadcast service transmission mode in a certain area. The primary service policy is a basic regional availability policy, generally, the scheduling system is not directly served, and only when the secondary service policy is unavailable, the primary service policy can be used for random service system selection and random transmission link selection.
Specifically, the available service type and the access network type of the corresponding area may be determined according to the area identifier, and the primary service policy may be determined according to the determined service type and the determined access network type, where the available service type includes whether DVB (digital video broadcasting) live broadcast service and/or IP (internet protocol) live broadcast service is supported, and the access network type includes whether DVB transmission and/or IP transmission is supported. As shown in table 1, it is a storage format schematic of the primary service policy:
TABLE 1
Region identification Available service types Available transmission links
Wherein:
area identification: for uniquely identifying operating areas with the same service system or the same access network, for example: if the access networks of some adjacent cells are all modified to FTTH (fiber to the home), the access networks can be assigned as an area. The area identifier can be uniquely identified by the operating agency according to the operating range.
Available service types: the method is used for identifying the type of the available live broadcast service system in a certain area, which can be represented by 2 bits; for example, code 01 means that only DVB live systems are supported; code 10 indicates that only an IP live system is supported; the code 11 represents that the DVB live broadcast service and the IP live broadcast system are simultaneously supported; code 00 is a reservation.
Available transmission links: which is used to indicate the type of access network available in the corresponding area, and which can be expressed in 2-bit bytes. For example, code 01 means that only DVB transmission mode is supported; 10 represents that only IP transmission modes are supported, including an IP multicast transmission mode and an IP unicast transmission mode; the code 11 indicates that the DVB transmission mode and the IP transmission mode are simultaneously supported; and (5) reserving the code 00.
The determination process of the primary service policy can be divided into the following two cases: an initial state and an operational state. In an initial state, all area representations in a live broadcast service operation range are traversed, for each area, an available service type and an access network type of the area are obtained, and an available service system and an available transmission link of the area are confirmed accordingly. In the running state, through the interface with the service system and the network management system, once the change of the available service type and the access network type is detected, the primary service strategy is updated.
In specific implementation, as shown in table 2, it is a schematic description of a primary service policy:
TABLE 2
Figure GDA0002467195410000091
Figure GDA0002467195410000101
And during specific implementation, the determined primary service strategy is stored in a strategy library.
The secondary service policy is used for determining a service mode, a transmission mode and a protection mode of a certain channel in a certain area. The live broadcast service scheduling system can schedule and protect the live broadcast service system and the transmission link in the designated area based on the secondary service strategy.
In specific implementation, the heat information of the corresponding channel may be determined according to the channel identifier, and a secondary service policy may be determined according to the determined primary service policy and the heat information, where the secondary service policy includes whether to start the primary/standby service protection and/or whether to start the primary/standby transmission mode protection, the live service system includes a primary service system and a standby service system, and the transmission mode includes a primary transmission mode and a standby transmission mode.
As shown in table 3, it is a storage structure schematic of the secondary service policy:
TABLE 3
Figure GDA0002467195410000102
Wherein:
area identification: for uniquely identifying operating areas with the same service system or the same access network, for example: and if the access networks of some adjacent cells are all reformed into FTTH, the access networks can be assigned as a region. The region identifier is uniquely identified by the operation mechanism according to the operation range.
And (3) channel identification: the system is used for uniquely identifying the live broadcast service channel of the operation mechanism, and the channel number is made into a unique identifier by the operation mechanism according to the service requirement.
Service protection identification: for identifying the service mode, it can be identified with 2 bit. For example, code 01 indicates that only the primary service system is turned on; code 10 indicates that only the standby service system is turned on; the code 11 indicates that the main service system and the standby service system are started simultaneously; and (5) reserving the code 00. And under the default condition, the service protection identifier is assigned to be 01.
And (3) transmission protection identification: for identifying the transmission mode, it can be identified with 2 bits. For example, code 01 indicates that only the primary transmission scheme is used; code 10 indicates that only alternate transmission is used; the code 11 indicates that the primary transmission mode and the standby transmission mode are used simultaneously; and (5) reserving the code 00. By default, the transmission protection representation is assigned a value of 01.
A main service system: the main service system is used for identifying a certain channel in a certain area and can be identified by 2 bits; for example, code 01 represents a DVB live system; code 10 represents an IP live system; code 11 and code 00 reservations.
The main transmission mode: the primary transmission mode used for identifying a certain channel in a certain area can be identified by 2 bits. For example, code 01 represents a DVB transmission; code 10 represents IP multicast transmission; code 11 represents IP unicast transmission; and (5) reserving the code 00.
The standby service system: the standby service system is used for identifying a certain channel in a certain area and can be identified by 2 bits; for example, code 01 represents a DVB live system; code 10 represents an IP live system; code 11 and code 00 reservations.
Standby transmission mode: the spare transmission mode for identifying a certain channel in a certain area can be identified by 2 bits. For example, code 01 represents a DVB transmission; code 10 represents IP multicast transmission; code 11 represents IP unicast transmission; and (5) reserving the code 00.
