Group charging ID (GCID) allocating and issuing method and GCID processing entity

Abstract

The invention discloses a group charging ID (GCID) allocating and issuing method and a GCID processing entity. The GCID allocating and issuing method includes the steps that after the GCID processing entity receives a request message, whether an allocated GCID corresponding to a current MTC group communication service exists or not is inquired according to information, related to the current MTC group communication service, in the request message; when the GCID corresponding to the current MTC group communication service is not found, a new GCID is allocated to the current MTC group communication service, and the new GCID is forwarded to other network elements involved in the current MTC group communication service. By the GCID allocating and issuing method and the GCID processing entity, GCIDs can be allocated and issued effectively, and it can be ensured that the allocated unique GCID can be associated with group CDRs generated by different network elements involved in the same charging event.

Description

technical field [0001] The present invention relates to the technical field of Machine Type Communication (MTC, Machine Type Communication), in particular to a method for allocating and issuing group charging IDs and a group charging ID processing entity. Background technique [0002] Machine-to-machine (M2M, Machine to Machine) communication, also called MTC communication, is a communication between a machine terminal and a machine terminal, or between a machine terminal and a machine-type application server. MTC communication can be widely used in transportation (such as logistics scheduling, positioning and navigation), electric power (such as remote meter reading, load monitoring), city management (such as elevator monitoring, street light control) and home (such as elderly care, home security), etc. It can communicate with the operator's network. [0003] figure 1 It is a schematic diagram of the mobile network architecture of MTC communication in the prior art, which...

[0009] 2. When multiple terminals in the group are connected to different signaling plane network elements (for example, MTC terminals reside in different MMEs) and send MTC service requests to different signaling plane network elements, it may be the same MTC group services are assigned multiple group charging IDs, so that the billing system cannot identify the same billable MTC group communication service performed by the same group of terminals according to multiple group charging IDs; therefore, how to maintain the group The charging identity is uniquely allocated and shared in different signaling plane network elements, which is very important for the charging system;

However, the prior art cannot provide a solution capable of achieving the above-mentioned purpose
