[0052] see figure 1 , the first embodiment of the handover method in the embodiment of the present invention specifically includes:

[0053] 101. The private network user equipment receives the measurement control message sent by the access network equipment;

[0054]The private network user equipment receives the measurement control message sent by the access network equipment. The measurement control message carries the relevant information of the private network user equipment's measurement period to the access network equipment. The relevant information of the measurement period is used to instruct the private network user equipment to determine The measurement period of the neighboring cell measurement;

[0055] The relevant information of the measurement cycle may be a specific value or index value of the measurement cycle, and the specific value or index value of the measurement cycle is determined by the access network device;

[0056] Alternatively, the relevant inf...

[0078] see figure 2 , the following is the second embodiment of the switching method in the present invention, specifically:

[0079] 201. The access network device sends a measurement control message to the private network user equipment;

[0080] After obtaining the measurement cycle of the private network user equipment's adjacent cell measurement, the access network device generates a measurement control message, which carries the relevant information of the measurement cycle, and the relevant information of the measurement cycle is used to instruct the private network user equipment to determine the adjacent cell measurement measurement cycle;

[0081] The relevant information of the measurement cycle may be a specific value or index value of the measurement cycle, and the specific value or index value of the measurement cycle is determined by the access network device;

[0082] If the relevant information of the measurement period is a specific value, for example: the...

Abstract

The embodiment of the invention discloses a switching method and also provides corresponding private network user equipment, access network equipment and a system. The method comprises the following steps that: private network user equipment receives a measuring control message, which is sent by access network equipment, determines the measuring period according to relevant information of a measuring period, performs an adjacent measurement within the measuring period to acquire a measuring report about quality of an adjacent signal, sends the measuring report to access network equipment and switches according to the switching command after reception of a switching command which is sent by access network equipment. By the technical scheme, the measuring period is adjustable and controllable, so the switching time delay meets communication requirement of a private network scene.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a switching method, private network user equipment, access network equipment and a system. Background technique [0002] With the development of wireless communication technology, users have higher and higher requirements for wireless services. In order to meet the needs of faster service transmission rate, shorter delay and wider frequency band, the next generation network NGN (Next Generation Network), such as LTE (Long Term Evolution, long-term evolution) technology came into being. [0003] The content defined by the LTE standard protocol is mainly aimed at ordinary user equipment and general telecommunication networks, and the requirements for performance indicators are all aimed at ordinary users. But in some special application scenarios, some dedicated networks will be involved. These special application scenarios include but are not limited to: the transportatio...
