Definitions

  • the present invention relates to the field of communications, and in particular, to a method and system for implementing high priority services. Background technique
  • a high-priority service is defined, which is characterized in that when a user initiates a high-priority service request, the network preferentially processes the service for the user. Requests, even when there is congestion or insufficient resources in the network, will give priority to the user. However, not all users can initiate high-priority services. The user must be contracted with the network and the authenticated user can initiate high-priority services. Therefore, when the user initiates a high-priority service request, the network needs the service. Request for authentication and provide the user with a service of high priority service when the requirements are met.
  • FIG. 1 is an architectural diagram of an existing IMS network, including a User Equipment (UE), a Home Subscriber Server (HSS), and an IMS Core Network Session Control Function (CSCF), such as a proxy session control function entity ( P-CSCF), Service Session Control Function Entity (S-CSCF).

  • the HSS generally saves the user's data information, including User's signing information, etc.

  • 2 is a flow chart of the network providing partial subscription information to the P-CSCF in the IMS system, and the process includes the following steps:
  • Step 201 The UE initiates a registration request to its IMS access point P-CSCF.
  • Step 202 Through the S-CSCF query function, the network allocates an S-CSCF for the user to serve, so that the registration request is routed to the S-CSCF.
  • Step 203 The S-CSCF queries the user data in the HSS.
  • Step 204 The HSS returns the queried user data to the S-CSCF, where the data includes related data such as whether the user subscribes to the high priority service or the like;
  • Step 205 After the network authentication user succeeds, the S-CSCF returns a 200 OK response to the user; Step 206, the P-CSCF returns the 200 OK to the user, and the user registration is successful; Step 207, when the registration is successful, the P-CSCF The user's S-CSCF initiates a subscription request, subscribes to the user's registration related information, and some service subscription information;
  • Step 208 The S-CSCF determines that the subscribed user of the P-CSCF has successfully registered, and then receives

  • Step 302 After receiving the high-priority service request, the P-CSCF determines whether the user can initiate the high-priority service, and the judgment basis is the user subscription data obtained in the previous subscription process.
  • Step 303 When the P-CSCF determines that the user meets the requirements When a high-priority service request is sent, a high-priority bearer is set up for the user, and the service request is preferentially forwarded, and the high-priority service identifier is retained in the forwarded service request.
  • Step S304 The S-CSCF determines the high-priority service. Since the P-CSCF has judged that the user meets the high-priority service, and the user data on the P-CSCF is notified by the S-CSCF, the S-CSCF is at this time. Similarly, the user is judged to be in a high priority service, and the S-CSCF preferentially forwards the service request to the UE-2 as the called party.

  • Priority service and the P-CSCF determines whether to provide high priority services to users according to the judgment result of the S-CSCF.
  • a timer is set; and the P-CSCF determines whether to provide the user with a high priority service according to the information obtained before the timer expires. Therefore, it is possible to avoid the occurrence of a legitimate high-priority service request that is unexpectedly failed due to the temporary lack of high-priority subscription data of the user, and to ensure the smooth implementation of legitimate high-priority service requests and improve user satisfaction.

Abstract

La présente invention concerne un procédé et un système destinés à un service à haute priorité. Dans le procédé comme dans le système, quand une unité de fonction de contrôle de session d'appel proxy (P-CSCF) est incapable de déterminer s'il faut ou non fournir à un utilisateur le service à haute priorité, un jugement pour savoir s'il faut ou non fournir à l'utilisateur le service à haute priorité est effectué par une unité de fonction de contrôle de session d'appel (CSCF) ; puis, sur la base du jugement effectué par l'unité CSCF, l'unité P-CSCF détermine s'il faut ou non fournir à l'utilisateur le service à haute priorité. De manière alternative, quand l'unité P-CSCF est incapable de déterminer s'il faut ou non fournir à l'utilisateur le service à haute priorité, un temporisateur est réglé ; puis, sur la base des informations acquises avant l'expiration du temporisateur, l'unité P-CSCF détermine s'il faut ou non fournir à l'utilisateur le service à haute priorité. Dans les présents procédé et système, des échecs inattendus de demandes légales pour un service à haute priorité refusées en raison d'un manque momentané de données de souscription à haute priorité de l'utilisateur peuvent être réduits, des efforts sont déployés pour un traitement régulier des demandes légales afin de maximiser le service à haute priorité, améliorant ainsi la satisfaction de l'utilisateur.
