specific Embodiment approach 1

[0090] Specific embodiment one, the cross-identity registration method of the same group user of public network cluster based on TD-LTE,

[0091] The identity registration of user registration to the cluster network is realized by the following steps:

[0092] Step 1. The user actively initiates a registration request for trunking communication, and sends attachment request information to the base station;

[0093] The attachment request information includes the user's IMSI (International Mobile Subscriber Identity) or GUTI (User's Temporary Identification), and also includes user network capacity (UE network capacity) information, packet data network type (PDN Type) information, attachment type ( Attach Type) information, non-access stratum sequence number (NAS sequence number) information, non-access stratum (NAS-MAC) information and selected network indication RRC parameters;

[0094] Step 2, the base station receives the attachment request information in step 1, and obtai...

Abstract

The invention discloses a cross identity registration method for co-group users of a time division-long term evolution-based (TD-LTE-based) public network and cluster and relates to the field of wireless communication, in particular to a cross identity registration method for the co-group users of the public network and the cluster. The invention aims to solve the problem that cross identity registration cannot be realized under a TD-LTE public network and a TD-LTE private network. A method for switching users registered in the public network to users registered in the cluster is characterized in that switching is realized under the conditions that the users complete bidirectional authentication with a cluster application (APP) by a bearing surface and user group information and the priority are synchronous. A method for switching the users registered in the cluster to the users registered in the public network is characterized in that the switching is realized under the conditions that a cluster network is detached but registration statuses of the users in the public network are kept. The cross identity registration method for the co-group users of the TD-LTE-based public network and cluster is suitable for the cross identity registration of the co-group users of the TD-LTE-based public network and cluster.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for cross-identity registration of users in the same group of public network clusters. Background technique [0002] The TD-LTE public network trunking service system, relying on the TD-LTE system, is an important branch of the new generation broadband wireless communication system and has broad application prospects. The user terminal can work in the public network system and the private network system at the same time in the system, and can switch between various working modes according to business needs. [0003] At present, users cannot realize cross identity registration under TD-LTE public network and private network. Contents of the invention [0004] The present invention aims to solve the problem that the cross-identity registration under the TD-LTE public network and the private network cannot be realized at present, thereby providing a TD-LTE-based pub...
