Problems solved by technology

[0007] In the research and practice process to the prior art, the inventor of the present invention finds, when many users gather in some sub-districts, some users are forced to switch to neighboring cells by adjusting handover parameters, although the call drop rate / Blocking rate, but at the same time, it will also lead to a decline in spectral efficiency, especially when the user is far away from the neighboring cell, the spectral efficiency decline is more obvious, resulting in a decline in user experience

Embodiment 1

[0045] This embodiment will be described from the perspective of a user terminal. Specifically, the user terminal may be a mobile phone, a notebook computer, a personal computer (PC, Personal Computer) and the like.

[0046] A method for accessing a mobile communication network, comprising: obtaining the session matching degree of each cell, and selecting a cell for access according to the session matching degree of each cell. Wherein, the session matching degree is obtained according to the session type of the session to be initiated by the user terminal, the session data rate available to the user terminal in each cell, and the load balancing parameters of each cell.

[0047] Such as figure 1 As shown, the specific process can be as follows:

[0048] 101. Obtain the session matching degree of each cell, wherein the session matching degree is based on the session type of the session that the user terminal needs to initiate, the session data rate (equivalent to signal streng...

Embodiment 2

[0070] Embodiments of the present invention will be described from the perspective of a network side device, and the network side device may specifically be a base station of a cell (hereinafter referred to as a cell for short) or the like.

[0071] A method for accessing a mobile communication network, comprising: obtaining the session type of a session that needs to be initiated by a user terminal, the session data rate available to the user terminal in this cell, and the load balancing parameters of the cell; according to the obtained session type, the user The session data rate available to the terminal in this cell and the load balancing parameters of this cell calculate the session matching degree of this cell; the calculated session matching degree is sent to the user terminal, so that the user terminal selects a cell for access according to the session matching degree; Or select a cell for the user terminal according to the session matching degree, and notify the user t...

Embodiment 3

[0088] On the basis of the second embodiment, further, in order to control the adverse effects brought by the handover and improve the efficiency of the spectrum, the load balancing parameter, that is, the frequency migration factor a c，ss and switching factor a c，ho Adjust, and then according to the obtained session type, the session data rate available to the user terminal, and the adjusted frequency migration factor a c，ss and the adjusted switching factor a c，ho Calculate the session matching degree of this cell, so that the system can automatically optimize the user's cell selection. For example, when the spectrum owned by a cell or the load of the cell changes, the frequency migration factor a needs to be adjusted c，ss ; and when there are many session handovers in a cell, it is necessary to adjust the handover factor a c，ho .

[0089] (1) Frequency migration factor a c，ss

[0090] The frequency migration factor a can be adjusted according to the available spectrum...

Abstract

A method for accessing to a mobile communication network, comprising: acquiring a session matching level for each cell, which is calculated based on a session type of a session initiated by a user terminal as needed, a session data rate available to the user terminal of each cell and load balance parameters of each cell; accessing to a cell selected according to the session matching level for each cell. Further, it also provides another method for accessing to a mobile communication network, and corresponding user terminal, network-side device and communication system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for accessing a mobile communication network. Background technique [0002] With the continuous expansion of the scale of mobile communication networks and the development of miniaturization of base stations, the number of network elements that operators need to maintain is increasing rapidly, and the required maintenance costs are also increasing. For this reason, people have proposed a self-organization network (SON, self-organization network) mechanism, hoping to achieve the purpose of saving operating costs by realizing as much automation as possible in the planning, deployment, and operation and maintenance stages of mobile communication networks. [0003] In order to facilitate problem research and standardization work, the prior art has begun to define a series of use cases (use cases) for SON standardization, and discuss correspo...
