Background

In the resource allocation process of the soft switch power communication network in the existing method, once a network resource is occupied by a certain service application, the network resource is monopolized until the service is finished, and the waste of the network resource is greatly caused. The existing methods do not realize network channel resource sharing in the soft switch power communication network.

Further, in step S1, Δ t is a constant and represents a period of time, and the value is selected according to the current service condition and is set empirically. For services with high real-time requirements such as voice services, a small value of Δ t is selected so as to ensure the real-time performance of voice services. For data traffic, Δ t is chosen to be large.

The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

A method for distributing power communication network resources based on soft switch is carried out based on the existing power communication network architecture of soft switch, as shown in figure 2, the service request is executed by the service network plane of the lower layer, and the service network plane includes a scheduling data network and a scheduling switching network in the power communication network. The networks of the service network plane may be interoperable or isolated from each other. The actual situation depends on the scale of network construction. Generally, for the construction of a power communication network in a small-scale area, the intercommunication between the networks is realized. For the network construction of a large-scale area, it is common to adopt a state in which each network is independently constructed and isolated from each other. The service network plane performs service logic scheduling and forwarding on the service, and the actual processing and execution are completed by the underlying bearer plane. The architecture provided by the patent can be used for preprocessing service logic on a service network plane, a service logic preprocessing module can distinguish the current service logic and pre-combine the resource demand conditions among services, and the resource cost can be effectively reduced through the steps.

As shown in fig. 1, a method for allocating resources of a power communication network based on soft switching includes the following steps:

s1: setting a time period value delta t according to the service state;

s2: collecting the timeService in segment and according to arrival time t of service_iSequencing in an ascending order;

s3: starting from the first service, the bandwidth required by the nth service and the bandwidth required by the last nth service in the list are sequentially compared

S4: if the total bandwidth of the addition result is larger than the current bandwidth upper limit B₁Then return to step S4; if the total bandwidth of the addition result is less than or equal to the current bandwidth upper limit, the next step is carried out;

s5: the two services are combined for processing and removed from the list.

The method preprocesses all current service requirements, and performs service fragmentation and combination according to time, thereby realizing the improvement of resource utilization rate, and combines the services arriving for a period of time delta t in a service preprocessing module, combines the service requirements occupying full bandwidth, and processes the service requirements in a centralized way.

In this embodiment, at step S1, Δ t is a constant and represents a period of time, and the value is selected according to the current service situation and is set empirically. For services with high real-time requirements such as voice services, a small value of Δ t is selected so as to ensure the real-time performance of voice services. For data traffic, Δ t is chosen to be large.

In this embodiment, in step S2, the current service requirement is time slice divided according to the arrival order, and first, a time label is added to the service, where i ∈ [1]Natural number of (1), t_iRepresenting the arrival time of the current traffic.

In the present embodiment, in step S4, the current bandwidth upper limit B₁The calculation formula of (a) is as follows:

B₁＝U_num*U_ratio*U_bandwith*2

the number of users of a service is denoted as U_numThe call traffic rate is denoted as U_ratioThe unit bandwidth occupied by the service is expressed as U_bandwith；

Wherein, since the traffic is bidirectional, the bandwidth occupation needs to be multiplied by 2.
