Embodiment Construction

[0039] Preferred embodiments of the present invention are described in detail below.

[0040] Such as figure 1 As shown, the present invention provides a method for dynamically reserving resources for an emergency call, which is used in a TD-SCDMA system, and the method includes the following steps:

[0041] A1. Initialize the reserved resource information table of a certain cell; wherein, the information table records the number of resources that need to be reserved for emergency calls in the cell, as well as the logo, time slot and code channel information of the reserved resources; for example, the The information table is an array with a length of K. K represents the number of resources that need to be reserved for emergency calls in a certain cell. Each array element is a struct type, which records the flags, time slots and code channel information of the reserved resources. (that is, slot code channel distribution information), its format is shown in Table 1 below.

Abstract

The invention discloses a method for reserving resource for an urgent call dynamically. The method is used for a TD-SCDMA system. The method comprises the steps as follows: a reserved resource information list is initialized, wherein, a symbol, time slot and code channel information of reservation resource are recorded; when an ordinary business is accessed, the time slot and a code channel are selected for reserved resource of ordinary business access and urgent call access respectively, and the symbol of the current reserved resource and code channel information of each time slot are recorded; when the urgent call is accessed, an information list is inquired, whether vacant reserved resource exists is judged according the symbol, if the vacant reserved resource exists, the time slot andthe code channel corresponding to the reserved resource are accessed, and the symbol of occupied and reserved resource is set as being used; otherwise, the urgent call is accessed with business, and the time slot and the code channel are selected within a subdistrict. When the urgent call is accessed, the urgent call can be accessed into a system fast, thereby ensuring the instantaneity for accessing the urgent call, reducing the condition that the urgent call is refused due to the full load of the system and presenting the QoS requirement of different business grades.

Description

technical field [0001] The present invention relates to a method for reserving resources in a TD-SCDMA (Time-Division Synchronization CodeDivision-Multiple-Access, Time-Division Synchronization Code Division Multiple Access) system, and in particular to a method for dynamically reserving resources for emergency calls in a TD-SCDMA system Methods. Background technique [0002] In the TD-SCDMA system, when a new service is accessed, it is necessary to allocate appropriate time slots and channelization code resources (ie, code channels) for each service to be accessed. When selecting a time slot for a service, it is not only necessary to meet the resource requirements of the service, but also to choose a time slot with a lighter load and less interference as much as possible to ensure that the system has better transmission performance. When allocating channelization code resources for services, such as Figure 5 As shown, in the tree structure of the OVSF code, when a codewor...
