  • the switching center and the data base provide mobile service for the subscribers. Moreover, the switching center provides interworking function for the subscribers which is needed for speech and non-speech connections to external networks .
  • the subscribers connecting to the switching center may be classified according to different categories.
  • these categories comprise business, normal and telemetric categories .
  • the switching center When the data base capacity increases so that data of more subscribers are present than subscribers can be handled by the switching center communicating with the data base, the switching center cannot perform all its functions without overloading .
  • the service for the subscribers connecting to the overloaded switching center is decreased.
  • this subscriber may not be handled by the switching center anymore, although a subscriber of the telemetric category which has connected to the switching center just before the business subscriber is handled.
  • the service should be provided even in switching center overload situation.
  • This object is achieved by a switching method comprising the steps of: assigning priorities to subscriber categories; combining subscriber categories of same priority into a subscriber group; reserving resources for each subscriber group; receiving a resource usage request in connection with a subscriber connection request from a subscriber; determining the subscriber group to which the subscriber belongs; and allocating a resource for the subscriber out of the reserved resources for this subscriber group.

  • VLR capacity in GSM When the data base capacity (VLR capacity in GSM) is enlarged, switching center overload situations may become more frequent. According to the present invention, users can be prioritized and acceptable service levels for users with high priority can be ensured also in switching center overload situations.

  • the switching center 2 communicates with a data base 3 which stores data of subscribers connected to the switching center 2.
  • the switching center 2 is able to perform ticketing, i.e. allocates resources for subscribers connecting to the switching center 2 which will be described in connection with Fig. 2.
  • the switching center 2 assigns a priority to each subscriber category used. As it is shown in Fig. 4, there may be a business category, a normal category and a telemetric category. According to the preferred embodiment, the switching center 2 gives the business category a high priority and the normal and telemetric categories a low priority (step SI in Fig. 2) . Then the switching center 2 groups together the categories having the same priority. That is, the business category forms a subscriber group having high priority and the normal and telemetric categories form a subscriber group having low priority (step S2) .
  • the switching center 2 reserves resources for each subscriber group (step S3) .
  • the switching center 2 may for example reserve 60% of its resources for the group with high priority and the remaining 40% for the group with low priority.
  • the switching center 2 receives a resource usage request from a subscriber 1 in connection with a subscriber connection request (step S4), it checks to which category or subscriber group the subscriber 1 belongs (step S5) .
  • the switching center 2 After having determined the group, the switching center 2 allocates a resource out of the resources reserved for the determined subscriber group for the subscriber 1 (step S6) .
  • Fig. 3 The allocation of resources according to the preferred embodiment will be described in more detail with reference to Fig. 3.
  • a connection request there can be several resource usage requests, and the connection setup fails if any of them fails.
  • the operation of Fig. 3 may be applied several times during a connection setup.
  • the switching center 2 When allocating a resource for the connecting subscriber 1, the switching center 2 first checks whether a resource for the determined subscriber group still is available (step S61 in Fig. 3) . If YES in step S61, the switching center 2 allocates the 'resource for the subscriber 1.
  • step S63 the switching center 2 checks in step S63 whether the determined subscriber group is a high priority group. If the switching center 2 detects in step S63 that the subscriber 1 belongs to a high priority group, i.e. the business category group according to the preferred embodiment, it advances to step S64 in Fig. 3.
  • step S64 the switching center checks whether a resource reserved for a subscriber group having low priority is available.
  • the switching center 2 checks in step S64 whether a resource reserved for the normal and telemetric categories is available .
  • step S64 the switching center 2 allocates a resource out of the resources reserved for the low priority group for the subscriber 1 belonging to the high priority group (step S65) .
  • resources for the business category group subscribers are low, resources may be taken from the telemetric and normal subscriber group.
  • subscribers are classified with respect to their category.
  • priorities are assigned to the different subscriber categories and categories with the same priority are grouped together.
  • the present invention is not restricted to two groups and there can be one group for each category.
  • Fig. 4 there may be a further dotted line between the normal and telemetric categories, forming three subscriber groups. Then, in case resources for the normal category group subscribers are running out, resources can be taken from the telemetric subscriber category group. Furthermore, a top priority group for emergency calls and the like can be introduced.
  • the resources of the switching center 2 are divided between the groups.
  • the high priority group has the biggest part of resources reserved.
  • the resource reservation for each subscriber group can also be made dynamically during operation.
  • priorities may be assigned dynamically to the subscriber categories during operation. According to Fig. 4, when the normal subscriber category is given the same priority as the business subscriber category, the dotted line in Fig. 4 moves down, thus forming a business and normal subscriber group and a telemetric subscriber group, and it becomes possible that a normal subscriber gets resources also from the business category if there are extra resources in this category.
  • users can be prioritized and acceptable service levels for users with high priority can be ensured also in switching center overload situations.
  • the present invention is not limited to a specific switching technology and is also applicable in packet switched networks like IP (Internet Protocol) networks.
  • IP Internet Protocol
  • switching is not limited to conventional switching performed in circuit switched networks, but it is to be interpreted broadly, i.e. including also the switching done e.g. in all IP networks, so that, in some cases, it could also be called routing.

Abstract

L'invention concerne un procédé de commutation ainsi qu'un élément de réseau (2) mettant en oeuvre ce procédé. Dans ledit procédé, des priorités sont attribuées à des catégories d'abonnés, les catégories d'abonnés de même priorité sont assemblées en un groupe d'abonnés et des ressources sont réservées pour chaque groupe d'abonnés. Lorsqu'une demande d'utilisation de ressource en relation avec une demande de connexion d'abonné est reçue d'un abonné (1), le groupe d'abonnés auquel l'abonné (1) appartient est déterminé et une ressource pour l'abonné (1) est attribuée parmi les ressources réservées à ce groupe d'abonnés.
