  • the B' SGSN sends a Cancel LocationAck acknowledgment message to the HLR; if the network detach procedure is initiated by the SGSN, then there is no such step.
  • each user terminal that is paged must perform a network detachment process separately, and only one detachment process of the user terminal is shown in the figure.
  • the existing technology can also be used for paging, that is, the user ID is directly paged in the paging message without using the user list cell.
  • the ninth and the second embodiments are similar to the first and second embodiments, that is, the information of the subsequent action indication is carried in the paging request message sent by the user in the single idle state, and the difference from the first embodiment and the second embodiment is that The subsequent action indication information carried here is the detachment indication information.
  • the embodiment of the present invention carries the indication information indicating that the user terminal performs subsequent actions in the paging request message sent by the core network, and indicates that the user terminal subsequently initiates the corresponding process; or, the core network sends the corresponding information.
  • the paging request message carries the user list, and can page multiple users at a time, thereby saving signaling overhead, streamlining the process, and reducing the delay in the re-attachment process in the evolved network.
  • the method for carrying multiple users by paging the user list in the paging request message is applied to the detachment process in the existing network, which can also save signaling overhead and simplify the process. , to reduce the purpose of delay.

Abstract

Procédé et appareil d'appel radio dans un réseau de communications, le procédé d'appel radio comprenant les stades suivants : le réseau central envoie un message de demande d'appel radio au réseau d'accès, qui utilise les informations pour indiquer les prochaines actions pour le terminal utilisateur; sur la base de ce message de demande d'appel radio reçu, ce réseau d'accès envoie le message d'appel radio au terminal de l'utilisateur cible, qui utilise les informations pour indiquer les prochaines actions; après réception de ce message d'appel radio, la borne utilisateur lance un processus approprié sur la base de ces informations pour indiquer les prochaines actions. Selon un autre procédé d'appel radio, dans un réseau de communications, le message de demande d'appel radio que le réseau centrale envoie à réseau d'accès utilise la liste d'utilisateur pour réaliser l'appel radio de plusieurs utilisateurs à la fois. Cette invention permet de réaliser des économies en termes de consommation de messages, de prétraitement des flux et de réduction des retards dans le réseau.
